DISCLAIMER:
Rooting your phone and using custom Recoveries and ROMS have risks and may result in bricking your device, and has nothing to do with Google or the device manufacturers. In case of any mishap I am not responsible if you brick/ruin your phone in any way.
Basic computer skills are required and minimal knowledges about phones and phones utilities too.
Make sure that whatever you do, you are doing it at your own responsibility.
This guide may be obsolete now for the new MTK SOC's powered phones, but it will give you some ideeas about how MTK phones world works (especially if you are new to this).
Why this thread?
- Because of all those PMs I receive with questions about how to do this or how to do that.
These things aren't they covered here on XDA?
- Some of them are, some don't, or they are spread over the forum in different sections, different threads. Also I will present here my vision about how to do things, and in some parts is different than the others existent.
I tried to document all steps with images for a better understanding, and to make it easy for people who don't understand well English (also I don't claim that my English is very good, but I'm trying).
1. If you want to use your phone as you buy it, then this thread is not for you, but if you want to use a custom recovery, to install a custom ROM, or some modds, keep reading.
2. First big step in our journey is to root your phone, which most of you know that means to get root (administrator) access to your phone's OS - just a simple definition. With an unrooted phone, you can't do much, and that means you will use it pretty much as you buy it - see first point.
There are multiple methods to root your phone, through an application from your phone, with an executable software from your PC or by flashing a zip modd from recovery (only for custom recoveries).
A. The best rooting application at the moment (in my opinion), is Framaroot.apk, developed by alephzain - please stop by his thread and drop a thanks, or if you can buy his donnation app from Playstore to support his work. You can download this app from official thread.
B. For rooting with a software from PC, I know three big candidates: oneclickroot, kingoroot and srsroot. I know there are more, but I mentioned only the best known.
C. Rooting zip archives are two, to choose from: chainfire's and koush's. Although, these require to have a custom recovery installed.
Any method you choose, be sure to check the phone models reported to work for, and look for your model.
Next, I will present step by step what I call "the beginner's routine":
root the phone;
make a nvram backup;
make a stock ROM backup;
generate a custom CWM and flash it;
patch to unsecure the boot and flash it;
get a Root File explorer;
create a custom recovery by porting one.
Prerequisites:
you must have an account on XDA; if you don't, then create one - and remember, at beginning you will not be allowed to post but you can hit Thanks for people I will mention here.
use a computer with Windows XP or 7 (I don't know if it will be any problem in vista or windows 8, but I didn't tried them, so I can't tell).
a phone with MTK CPU, obviously!
these tools:
MTKDroidTools of rua1's - download it from his thread and hit Thanks or donate to him, please
SPFlashTools or MTKFlashTools.
MTK USB Drivers and your phone manufacturer's USB Drivers if they provide that.
For MTK USB Drivers, there are many sources, but I couldn't find any official source. Few known sources: here and here.
* ADDED: For windows 7 and xp I repacked all MTK needed drivers, bundled with latest google usb drivers and using windows driver installer. Some of the drivers are not digitally signed, so when the prompt window ask you if you want to install unsigned driver (it will be several times) select yes or ok. The advantage is that this method is easier than manual method and also will create an entry in installed programs, and later if you want you can uninstall them in control panel uninstall program. Before installing this you need to remove old drivers installations - use usbdeview (download it x86 or X64), and look for VendorId 0bb4 and 0e8d, and uninstall every device with these Ids. Packed drivers are attached to this post; take what corresponds to your windows version. Unpack the archive, open the folder and run dpinst.exe. More info inside: read info.txt (especially for XP).
Install all needed drivers.
A good text editor (Notepad++ or Geany) installed.
Adb installed in your computer from Android: here, here and here you can learn how.
Credits and Thanks:
@alephzain - Framaroot developer
@rua1 - developer of MTKDroidTools
@Chainfire - SuperSU developer
@Koush - so many things!!!
@michfood - developer of Boot Recovery pack/unpack tool
and, even if it is not presented here, but because I use a lot his tools in Linux:
@bgcngm - for his Unpack/Repack scripts
1. Root the phone.
For this step I choose to use Framaroot.apk, first because I don't like to install unnecessary software on my computer, and second because it supports a very large number of MTK phones. So, go to alephzain's thread and download the apk, then connect your phone to PC with USB debugging enabled, turn on USB Mass storage and copy Framaroot.apk to your sdcard root, or in internal storage if you don't have a sdcard in your phone. Eject phone's USB storages from PC, and turn off USB Mass storage from phone.

"lightbox_download": "Download",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Go to apps drawer, find File Manager, open it, navigate to location where you placed Framaroot.apk touch on it and install it. After that go back in apps drawer and open the newly appeared Framaroot. In that window you have to specify which exploit to use for getting root access. If you don't know it's not a problem, you can try each one until you see the Success message (for me was Barahir). If none of them works, then you have to find a different method to root. After success patching, reboot the phone and then you will see SuperSU.apk in your apps drawer. Now you have root access!
2. Install a Root Explorer.
I prefer ESFileManager, but you can choose what you like. This can be installed free from Playstore, or if you have it downloaded in your PC, use same steps as in Framaroot case, and install it.
Then open the app and let's activate the Root Explorer in it.
But, here you can choose a different view style instead of default big icons - I like Medium Icon view.
Touch on Globe symbol from upper left corner to open Advanced Tools menu, and select Tools (last one). In the list that opens, scroll down until you see Root Explorer entry and touch "OFF" button to activate it. You will be prompted to Grant Superuser access - Grant it! Then, touch on "Root Explorer" text and in the popup window select Read/Write, and in next window select all radios from RW column.
That's it, ESFileManager is now a powerfull Root Explorer.
3. Make a backup.
This means actually make two backups, one for nvram and one for the whole stock ROM. Why to make a backup for nvram? Because it is very easy in MTK phones to mess up with it, and you may loose IMEI, mac address or to have other connectivity issues. This backup will be your insurance.
For this you need MTKDroidTools. Download it from rua1's thread (link in OP) and unzip it in a folder named "MTKDroidTools" on your primary (system) partition - this is important, and in other locations you may experience errors and malfunction.
Connect your phone in usb debugging mode to PC, then start MTKDroidTools as administrator and wait untill you see that MTKDroidTools recognize it and loads its data. The following pictures will show you how to check if you have usb debugging activated, and how MTKDroidTools looks with loaded phone data. In most of the phones, adb gets root access immediately, but in some "branded" ones that has to be achieved by click on the "ROOT" button next to "Adb Terminal" - Notice that if you don't see that ROOT button, that means you have already "root in shell". Also, if you have chainfire's SuperSU you will be prompted in the phone to grant root access to adbd, but if you have koush's Superuser, adbd gets root access by default.
Now, as I said first thing is to do a nvram backup. Click on "IMEI/NVRAM" button and next select both methods (bin and zip folder) and click on "Backup".
After that, it's time to do a stock ROM backup. This is important if you are going to try different custom ROMs and modds. This will assure you that you always have a way to start from the beginning in a clean state. Also makes easy to unbrick your phone if you have the misfortune to brick it.
Click on "root,backup,recovery" tab, and click on "Backup" button, then wait to finish. Be patient, this will take a while, and you can see progress logs in side window. At the end, a popup will prompt you to pack the backup. Now you know it is finished. I don't pack these backups, but you do what you think.
In this stage first thing I do is to generate a scatter file. You have one in that backup made before, or you can get one from stock firmware archive if the phone's manufacturer provide that, but let's see how to do it as it is, to understand the process, or to learn how to get one if we loose it or we are unsure if the one we have is good for our phone (this is important, because using a wrong scatter file it may damage your phone).
So, return to "Phone Informations" tab and click on "Blocks Map" button. A window opens with your phone partition structure. Click on "Create Scatter File" button and save it somewhere in your computer.
Mission complete for backup; you are assured now.
4. Generate a custom recovery.
This is mandatory if you want to use an easy way to backup, restore, flash or wipe ROMs and modds. Fortunately, rua1 has included in his tool all you need to generate one for your phone. This method is successfull for almost every MTK phone, but not for all. There isn't an universal method for anything.
So, enter again in "root, backup, recovery", select the radio "To choose the boot.img file" - by default is selected "Install already prepared files" - and click on "Recovery and Boot" button.
When prompted, select the boot.img from previous backup folder and click Yes to make CWM recovery automatically. First you will be prompted to flash a patched boot.img in your phone - click Yes to get an unsecured boot, then next message will ask you to install the new created recovery in your phone. Click Yes and Yes to reload the phone in recovery mode.
The phone will shut down and reboot in recovery. Now you can see your custom recovery in place.
GOOD TO KNOW: you can't generate a recovery everytime you want to flash one, to use MTKDroidTools for flashing, and the adb method may not work for many MTK phones.
The most known method to flash a new recovery is by using SPFlashTools or MTKFlashTools, and an alternative method is with MobileUncle application from phone, but I will show detailed the FlashTools method. One thing though: if you want to use MobileUncle application, you have to use it from /system/app folder, not from /data/app. Many users say that the MobileUncle doesn't work to flash recovery: it show success, but rebooting to recovery reveal the old one. The reason? They installed MobileUncle from market, and that place the app in /data/app as a user app. In custom ROMs where the app is placed in system by ROM developer, the problem won't manifest. So, if you want to use MobileUncle, make it a system app not user app.
In order to do that, grab a copy of any of these tools from DR_MOOSAVI's thread (link in OP), unzip it in a folder "MTK_Flash_tool" in your primary(system) partition (C in my case), and notice the name have to not contain any spaces or special characters. In that folder create a new folder "Resources" or ROM or whatever name you want, also without spaces or special characters, and place in it your scatter file and recovery img you want to flash. Open Flash_Tool executable as administrator.
IMPORTANT: Your phone is not connected to the PC now. Swtich it off and wait, you will connect it later.
Continue in next post.
In Flash_Tools program window click on load scatter file, navigate to that folder you created and select your scatter. Now you can see your phone's partition structure. If the recovery you want to flash is named "recovery.img" it will be selected automatically, if not you have to click on recovery row in Location column and select your recovery from that folder.
Then click on "Download" button.
Now connect your phone to PC, just like that in power off. Some models enter automatically in download mode and the flashing process begins, but others don't. For some it is necessary to connect them without battery (battery removed), other need to press briefly Power and Vol Down button at same time and release them immediately. That you have to find for your phone from forums, other users, or by trying. When the phone enter in download mode you will see a red bar down in Flash_Tool window, followed by a yellow or other color one (that means the flashing process is taking place).
At the end a popup with a green circle or green checkmark will let you know that the flash was a success. Deconnect the cable and reboot the phone, or reboot it in recovery to see if the wanted recovery is installed. The most common method to boot in recovery from power off is to press Power and Vol UP at same time, and keep them pressed untill you see the logo, then release Power but keep pressing Vol Up untill the recovery UI appears. If Power and Vol Up doesn't work for you, start the phone normaly and connect the phone to PC, then open a command prompt window, and type " adb reboot recovery", then hit Enter during bootanimation. The phone will stop loading and will boot in recovery.

Thanks, but that is not something for begginers. Maybe meteos method with his app will be, but I'm not sure. Though, if someone want to procede to do that, you can edit your post and give more details, for people to know what is about, and to follow your link if they are interested.
Great guide @carliv.
Just a bit confused, as I usually flash custom recovery first before rooting my MTK phones (same goes for all my android devices). So, maybe, rooting and flashing custom recovery is interchangeable as the first step for MTK phones depending on their availability.

Yeah, well the next step in my guide is "do a stock ROM backup", and if you flash a custom recovery, that will not be a complete stock backup. With my method, any time, after flashing the stock backup, unroot and you will be in stock initial state.
I hope it's more clear now.

Got it. So this is more suited for those who do not have the original firmware for restoring their devices in case something goes wrong which is so like MTK phones. In any case, your guide is spot on. Hope the moderators would give this a sticky, if possible, since MTK phones are scattered all over xda.
How to Port to Device that have recovery-from-boot.p
Hello Everyone, and hello to @carliv,
Thanks to this Tutorial I have Manage to port in on a MT6582 and MT6572 Device with ext4 partition, but I just want to share some tips when porting the latest build of the carliv the tutorial here is complete except for one thing just in case you are ending up on a custom recovery not booting up and when you use the MTK Droid Root and Tools you will see this
-->Connect Device<--
there is a file blah blah - recovery-from-boot.p <----
Now that mess up the things but before we dig into that let me first share on how I got my Carliv Custom Recovery to Bootup
on the Tutorial there is a section that you need to use the MTK Unpacked tool right now once you have done that do all the other things that is written in the tutorial it will guide you on the whole process but on my end even though I followed the tutorial and all are correct I still end up on a Bootloop well I discovered that you need to copy the init file from the RUA1 CWMR that you got from the MTK Droid Root and Tools and overwrite the one on the Carliv Recovery after that once you have finish until on the Overwriting of the Kernel and Kernel header pack your Carliv Recovery using the MTK pack tool and now Flash it on your Device it will now boot :highfive:
BUT WAIT!! yes! it will boot but it will boot on the STOCK RECOVERY and that is because like what I said the recovery-from-boot.p is the culprit of the issue now you need to root your device which is on my end I used framaroot and then download the ES file manager and also follow the instruction of carliv on how to have the full ROOT R/W access and on your device, once your have done that got to this folders and delete this 3 files.
Be sure you have the R/W access or else this files will not be deleted
/system/recovery-from-boot.p
/system/etc/recovery-install.sh
/system/etc/recovery-resources.bin <--- I am not just sure if this is the right filename but it is almost the same will check it once again once I got to stock rom again :fingers-crossed:
and now once you have rebooted your smartphone to recovery mode it will now boot to the Carliv Custom Recovery.
But also take note that if you don't have that 3 files on your device your just good to go and it will boot to Carliv Custom Recovery without any issues.
it's just that 3 files makes the custom recovery always boot to stock recovery even though you do something else
hope this tip helps for some people having issue on a bootloop carliv custom recovery on doing the manual porting
and don't forget to hit the thanks button if this helps :victory:

Removing recovery-from-boot.p is enough, I think. Besides, CTR asks if you want to disable recovery-install.sh. That prevents the ROM from flashing stock recovery.

it depends on the unit, I just deleted the recovery-from-boot.p and still it boots up on the stock recovery that's why I needed to trace other files that still makes it boot on stock recovery, but then again not all units will have the same issues as mine
Thanks for your help, it works with my Huawei Honor 3X (mtk6592) !
Thanks Man!

[How to/MTK65xx] ROOT, Backup & Flash (MTKDroidTools, Spflashtool, CWM) [MTK Only]
Hi
This is a guide to ROOT, backup and flash your MTK65xx or Other device (Supported devices: http://forum.xda-developers.com/apps/framaroot/framaroot-supported-devices-t2722980 all credits to alephzain) written by s7yler.
More guides & reviews on my Youtubechannel http://www.Youtube.com/s7yler and http://s7yler.blogspot.com
(Tools used are Framaroot, MTKDroidtools/CWM and SpflashTool)
I will try to write this guide in step by step, so everyone can understand it. This is for PC and will work with Windows 7.
-> All is done by your own risk! this is just a guide to help people with the tools and process. <-
How to ROOT the phone first
1. Get the latest Framaroot apk here http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276
2. Download it and install it on the phone, open the Framaroot app on the phone.
3. Let it be on Install SuperSU, and try the last method, if that dont work, then try one of the 2 others.
4. Then it should say success root, and now reboot the phone.
5. After reboot the phone should be ROOTED, download root checker from the Play store and verify that your rooted.
How to make a simple backup (not completly 1:1) of your stock ROM / MTK phone
1. You have you brand new MTK phone.
2. What I do first is to install all possible drivers. So you go to your PC and install these apps/drivers:
Snappea - http://www.snappea.com/windows
Pdanet drivers - http://pdanet.co/a/ (When it ask what device you have in the install process, just say "Other")
Mediatek Preloader USB VCOM Drivers - (Install file) http://www.mediafire.com/download/cypm22rgs2k83ji/MT6577+USB+VCOM+drivers.rar and here the raw drivers http://www.magicdriver.com/driver4214-ver_1.1123.0.html
For the Preloader VCOM drivers for Windows 8 please read here, and follow this:
http://thebroodle.com/android/install-mediatek-mt65xx-usb-vcom-drivers-windows-8-8-1/
3. On your MTK phone you must in "Developer Options" enable "USB debugging mode".
4. Now download MTK Droid Tools here http://forum.xda-developers.com/showpost.php?p=49597819&postcount=922
5. Start MTK Droid Tools, and connect your phone with the USB cable to the PC. (if Windows install some drivers, then let it install them automatically).
6. Now on the first page of MTK Droid Tools, it should display all infos about the phone when you connect it.
7. If the sqare is Green, then you have root shell and ready, if its not green, press the ROOT button to the right in MTK Droid tools.
8. Click the "IMEI/NVRAM" button and then Backup to backup your IMEI/NVRAM, the backup files will be inside of the MTK Droid Tools folder.
Also you can manually write down your IMEI number just in case it should be lost.
9. Now go to the tap "root, backup, recovery" (in MTK Droid Tools).
10. Click the Backup button, and it will create a complete backup of your ROM. (in the end it will ask, if you want to pack it, just answer no)
11. When it is finished then also click "To prepare blocks for FlashTool", that will convert the backup to be compatible with Spflashtool. (choose the files.md5 inside the backup folder)
12. After the backup is done it will be inside "backup" in the MTK Droid Tools folder. And inside it there will also be a new folder called "!Files_to_FlashTool" Inside there the files for Spflashtool is. So when loading your backup with Spflashtool you must load the scatter file from inside there.
13. Now to install CWM (clockworkmod recovery) In MTK Droidtools, choose "To use boot from phone" and click the "Recovery and Boot" button. It will ask you a lot, just say yes every time, and it will end of sending CWM recovery to the phone and reboot into it on the phone. After you see CWM on the phone you know it is done. You can switch the menu with the volume keys, and the power is the select button.
14. Inside CWM you can also do a complete backup of your phone (remember to have enough space, you can do the backup to the internal storage OR to the SDcard - try "backup" if that fails then choose instead "backup to external sd" or vice versa). I recommed doing that because CWM makes another backup than the one made with MTK Droid Tools. So if you should get problems or loose something, you can always run your CWM backup into your phone and it will be as before.
15. After your done the backup, copy the backup also to a safe place on your PC. Just in case!
16. So now your Rooted, have installed CWM recovery, have a IMEI/NVRAM backup and a backup for Spflash Tools plus CWM backup.
To make a 100% FULL 1:1 (more advanced) ReadBack ROM backup using SP FlashTool please check these guides here, and learn how to:
http://mmx-unite2.blogspot.de/2014/08/how-to-create-readback-backup.html

or here:
http://pinoyscreencast.net/how-to/g...-smartphones-using-spft-mtk-droid-root-tools/
To flash a backup or ROM with Spflashtool:
Disclaimer: Don't flash another preloader and DSP_BL blocks! It is always dangerous! On some models of phones you will have a brick even if you download these blocks read from phone which you own! Always remove from them marks in SPFT! ALWAYS have a working backup of your original ROM before you flash a new unknown ROM. I take no responsibility for any harm done while attempting this!
1. Go download Spflash tool here http://forum.xda-developers.com/showthread.php?t=1982576
Both version 3 or 5 should be good to use. If your having problems with one of them or they crash, try this newer version here: http://forum.xda-developers.com/showthread.php?t=2650125
2. Disconnect your phone if connected with USB to the PC, and turn OFF the phone completely, also take out the battery if possible (but can also work with the battery inside the phone, for phones with builtin battery).
2. When you now again connect the USB cable to the phone with the PC while the phone is still off, Windows should popup and beginn to install the MTK65XX Preloader Drivers, this only happens if you installed the Mediatek Preloader USB VCOM Drivers correct in Windows. After they successfully installed, disconnect the USB cable again.
2. Start Flash_tool.exe to start the program
3. Now hit the "Scatter-loading" button, and go to the backup or ROM, inside the folder "!Flash files Spflashtool" load the scatter.txt file. (ALWAYS only load a ROM that is 100% made for your phone, flashing a wrong ROM may make your phone non-bootable)
4. When the scatter file is loaded, it will show all the content in the Spflashtool window.
5. If you only need for example to flash the EBR files, you can deselect all the others. But remember that it must be same ROM or backup.
6. Hit the "Download" button in Spflashtool. Then there should be some pink lines with colors showing that it loads the files.
7. When it stopps to flash/load, connect your phone with the USB cable, remember the phone must be OFF (and without the battery inside if possible to remove). If nothing happens then maybe it is necessary to press at the same time with connect of a cable the camera or volume buttons. For example, hold the volume up button down, insert the USB cable, and then insert the battery (still holding the volume up button down) when you hear it connect in Windows and the colored lines begins to move, let go off the volume up button.
8. Now it should connect (maybe Windows install some drivers by now - the MTK65xx Preloader drivers) and it will in the end continue to flash in Spflashtool when the phone is found and connected. (If you get PMT has changed error, you need to change in SP Flash Tool from "Download Only" to "Firmware Upgrade" but you will need a backup that contains ALL files then including the cache and usrdata files, or it will not allow to flash. Also the phone will be formatted first with Firmware Upgrade, and then flashed.)
9. Now wait while it flashes all files, when it is done, a window will popup white a Green circle. Now you can disconnect the cable, close Splflashtool and reboot the phone. The phone should now boot up with the new ROM.
10. A good thing can be to do a full factory reset after your booted or do it in CWM, to clear all caches. But not necessary.
To enter Recovery or Download mode - turn phone completly off then
Download mode = vol up + pwr (hold both down for several seconds)
Recovery = vol down + pwr (hold both down for several seconds)

Mediatek Preloader USB VCOM Drivers - http://www.magicdriver.com/driver4214-ver_1.1123.0.html
3. On your MTK phone you must in "Developer Options" enable "USB debugging mode".
4. Now download MTK Droid Tools here http://forum.xda-developers.com/showpost.php?p=49597819&postcount=922
5. Start MTK Droid Tools, and connect your phone with the USB cable to the PC. (if Windows install some drivers, then let it install them automatically).
6. Now on the first page of MTK Droid Tools, it should display all infos about the phone when you connect it.
7. If the sqare is Green, then you have root shell and ready, if its not green, press the ROOT button to the right in MTK Droid tools.
8. Click the "IMEI/NVRAM" button and then Backup to backup your IMEI/NVRAM, the backup files will be inside of the MTK Droid Tools folder.
Also you can manually write down your IMEI number just in case it should be lost.
9. Now go to the tap "root, backup, recovery" (in MTK Droid Tools).
10. Click the Backup button, and it will create a complete backup of your ROM.
11. When it is finished then also click "To prepare blocks for FlashTool", that will convert the backup to be compatible with Spflashtool.
12. After the backup is done it will be inside "backup" in the MTK Droid Tools folder. And inside it there will also be a new folder called "!Flash files Spflashtool" Inside there the files for Spflashtool is. So when loading your backup with Spflashtool you must load the scatter file from inside there.
13. Now to install CWM (clockworkmod recovery) In MTK Droidtools, choose "To use boot from phone" and click the "Recovery and Boot" button. It will ask you a lot, just say yes every time, and it will end of sending CWM recovery to the phone and reboot into it on the phone. After you see CWM on the phone you know it is done. You can switch the menu with the volume keys, and the power is the select button.
14. Inside CWM you can also do a complete backup of your phone (remember to have enough space, you can do the backup to the internal storage OR to the SDcard). I recommed doing that because CWM makes another backup than the one made with MTK Droid Tools. That is more complete. So if you should get problems or loose something, you can always run your CWM backup into your phone and it will be as before.
15. After your done the backup, copy the backup also to a safe place on your PC. Just in case!
16. So now your Rooted, have installed CWM recovery, have a IMEI/NVRAM backup and a backup for Spflash Tools plus CWM backup.
To flash a backup or ROM with Spflashtool:
1. Go download Spflash tool here http://forum.xda-developers.com/showthread.php?t=1982576
Both version 3 or 5 should be good to use. If your having problems with one of them, try another version.
2. Disconnect your phone if connected with USB to the PC, and turn OFF the phone completely, also take out the battery if possible (but can also work with the battery inside the phone, for phones with builtin battery).
2. Start Flash_tool.exe to start the program
3. Now hit the "Scatter-loading" button, and go to the backup or ROM, inside the folder "!Flash files Spflashtool" load the scatter.txt file. (ALWAYS only load a ROM that is 100% made for your phone, flashing a wrong ROM may make your phone non-bootable)
4. When the scatter file is loaded, it will show all the content in the Spflashtool window.
5. If you only need for example to flash the EBR files, you can deselect all the others. But remember that it must be same ROM or backup.
6. Hit the "Download" button in Spflashtool. Then there should be some lines with colors showing that it loads the files.
7. When it stopps to flash/load, connect your phone with the USB cable, remember the phone must be OFF.
8. Now it should connect (maybe Windows install some drivers by now - the MTK65xx Preloader drivers) and it will in the end continue to flash in Spflashtool when the phone is found and connected.
9. Now wait while it flashes all files, when it is done, a window will popup white a Green circle. Now you can disconnect the cable, close Splflashtool and reboot the phone. The phone should now boot up with the new ROM.
10. A good thing can be to do a full factory reset after your booted or do it in CWM, to clear all caches. But not necessary.

Hey sorry, I changed my text now. The ROOT part is not only for MTK phones, also other devices. Here is alephzains list of supported devices: http://forum.xda-developers.com/apps/framaroot/framaroot-supported-devices-t2722980
You also may try it on others, the worst there can happen is that it just says root failed, and not rooting the device. But then you at least have tried.

In Spflash tool load the scatter file from the backup or ROM directory where you also have all files including the modded EBR files, when loaded it will show all the content to flash, every line has a checkmark in front, uncheck everything but the EBR1 and EBR2. And then flash as I write in the guide. That way it will only flash the EBR1 and 2 to the phone.
Hope i can get this right

So you did install all the drivers I write about in my guide, and rebooted? Normally Spflash tool should recognize the phone after that. (and set the USB debugging mode to on?)
Thank you! Thank you! Thank you!

Hi!
For the last few days I was trying to find the right ROM for me. So I had to learn about MTK Tools and SP Flash tool and I even succeeded with loading different ROMs. What I did not succeed is to restore the original backup made with MTK tools. I followed the tutorial from the first post, the flashing operation ended OK but my smartphone (THL w200s) just wouldn't start. As a matter of fact it starts the beginning but after it passes the animated log it stops. I did not flash the CWM recovery on my device before creating the backup as I wanted to save a snapshot of the original ROM as it was from the factory. More than this, I installed a fresh ROM (I guess it was exactly the same with the default one), everything was OK, I rooted and made my settings (configure emails, etc.) and I made a backup with MTK tools. I had the same issue: I restored the backup with SP Flash Tools, flashing was OK but after that the phone would not start.
What am I doing wrong?

I will try to write this guide in step by step, so everyone can understand it. This is for PC and will work with Windows 7.
-> All is done by your own risk! this is just a guide to help people with the tools and process. <-
How to ROOT the phone first
1. Get the latest Framaroot apk here http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276
2. Download it and install it on the phone, open the Framaroot app on the phone.
3. Let it be on Install SuperSU, and try the last method, if that dont work, then try one of the 2 others.
4. Then it should say success root, and now reboot the phone.
5. After reboot the phone should be ROOTED, download root checker from the Play store and verify that your rooted.
How to make a simple backup of your stock ROM / MTK phone
1. You have you brand new MTK phone.
2. What I do first is to install all possible drivers. So you go to your PC and install these apps/drivers:
Snappea - http://www.snappea.com/windows
Pdanet drivers - http://pdanet.co/a/ (When it ask what device you have in the install process, just say "Other")
Mediatek Preloader USB VCOM Drivers - (Install file) http://www.mediafire.com/download/cypm22rgs2k83ji/MT6577+USB+VCOM+drivers.rar and here the raw drivers http://www.magicdriver.com/driver4214-ver_1.1123.0.html
3. On your MTK phone you must in "Developer Options" enable "USB debugging mode".
4. Now download MTK Droid Tools here http://forum.xda-developers.com/showpost.php?p=49597819&postcount=922
5. Start MTK Droid Tools, and connect your phone with the USB cable to the PC. (if Windows install some drivers, then let it install them automatically).

8. Click the "IMEI/NVRAM" button and then Backup to backup your IMEI/NVRAM, the backup files will be inside of the MTK Droid Tools folder.

9. Now go to the tap "root, backup, recovery" (in MTK Droid Tools).
10. Click the Backup button, and it will create a complete backup of your ROM. (in the end it will ask, if you want to pack it, just answer no)
11. When it is finished then also click "To prepare blocks for FlashTool", that will convert the backup to be compatible with Spflashtool. (choose the files.md5 inside the backup folder)
12. After the backup is done it will be inside "backup" in the MTK Droid Tools folder. And inside it there will also be a new folder called "!Files_to_FlashTool" Inside there the files for Spflashtool is. So when loading your backup with Spflashtool you must load the scatter file from inside there.
13. Now to install CWM (clockworkmod recovery) In MTK Droidtools, choose "To use boot from phone" and click the "Recovery and Boot" button. It will ask you a lot, just say yes every time, and it will end of sending CWM recovery to the phone and reboot into it on the phone. After you see CWM on the phone you know it is done. You can switch the menu with the volume keys, and the power is the select button.
14. Inside CWM you can also do a complete backup of your phone (remember to have enough space, you can do the backup to the internal storage OR to the SDcard - try "backup" if that fails then choose instead "backup to external sd" or vice versa). I recommed doing that because CWM makes another backup than the one made with MTK Droid Tools. So if you should get problems or loose something, you can always run your CWM backup into your phone and it will be as before.
15. After your done the backup, copy the backup also to a safe place on your PC. Just in case!
16. So now your Rooted, have installed CWM recovery, have a IMEI/NVRAM backup and a backup for Spflash Tools plus CWM backup.

To flash a backup or ROM with Spflashtool:
Never needlessly Download preloader and DSP_BL blocks! It is always dangerous! On some models of phones you will have a brick even if you download these blocks read from phone which you own! Always remove from them marks in SPFT! ALWAYS have a working backup of your original ROM before you flash a new unknown ROM.
1. Go download Spflash tool here http://forum.xda-developers.com/showthread.php?t=1982576
Both version 3 or 5 should be good to use. If your having problems with one of them, try another version.
2. Disconnect your phone if connected with USB to the PC, and turn OFF the phone completely, also take out the battery if possible (but can also work with the battery inside the phone, for phones with builtin battery).
2. When you now again connect the USB cable to the phone with the PC while the phone is still off, Windows should popup and beginn to install the MTK65XX Preloader Drivers, this only happens if you installed the Mediatek Preloader USB VCOM Drivers correct in Windows. After they successfully installed, disconnect the USB cable again.
2. Start Flash_tool.exe to start the program
3. Now hit the "Scatter-loading" button, and go to the backup or ROM, inside the folder "!Flash files Spflashtool" load the scatter.txt file. (ALWAYS only load a ROM that is 100% made for your phone, flashing a wrong ROM may make your phone non-bootable)
4. When the scatter file is loaded, it will show all the content in the Spflashtool window.
5. If you only need for example to flash the EBR files, you can deselect all the others. But remember that it must be same ROM or backup.
6. Hit the "Download" button in Spflashtool. Then there should be some pink lines with colors showing that it loads the files.
7. When it stopps to flash/load, connect your phone with the USB cable, remember the phone must be OFF (and without the battery inside if possible to remove). If nothing happens then maybe it is necessary to press at the same time with connect of a cable the camera or volume buttons. For example, hold the volume up button down, insert the USB cable, and then insert the battery (still holding the volume up button down) when you hear it connect in Windows and the colored lines begins to move, let go off the volume up button.
8. Now it should connect (maybe Windows install some drivers by now - the MTK65xx Preloader drivers) and it will in the end continue to flash in Spflashtool when the phone is found and connected.
9. Now wait while it flashes all files, when it is done, a window will popup white a Green circle. Now you can disconnect the cable, close Splflashtool and reboot the phone. The phone should now boot up with the new ROM.
10. A good thing can be to do a full factory reset after your booted or do it in CWM, to clear all caches. But not necessary.
To enter Recovery or Download mode - turn phone completly off then
Download mode = vol up + pwr (hold both down for several seconds)
Recovery = vol down + pwr (hold both down for several seconds)

I'm receiving an error message "SU inaccessible" after hitting the ROOT icon. The phone is a No.1 S7 MTK6589.
I previously tried using the Frameroot app but it failed as well.
Any ideas what the problem might be and how to solve?
Thanks,
Ruby
UPDATE
I have updated the Original Post with a video now, that show the whole process how to flash and use SP Flash Tool.
As always, everything is done at your own risk. It is just a guide. This video is for education only.

Fun accident
Well here's my story.
I was trying to debrand some Huawei Y330-U05 in order to resell them. My first clue was to root the devices and remove all the Entel PCS crap, but I was unable to remove the Boot Splashscreen. So I looked over the net and I could not find a compatible ROM for my model. I downloaded a Y330-U01 ROM from Europe and I tried to flash it figuring that later I'd have to fix the 3G bands. FlashTools did not let me do that and I had the stupid idea to boot the biit.img and recovery.img from the U01 into the U05 with MTKdroidTools. Bricked the phone, and the only way to bring it back was to use the U01 ROM and flash it back. I changed my device from U05 to U01, like I wanted at first but I cant change the 3G bands and I don't have 3G connnection now.
I can't flash back the U05 backup ROMs I did from the phone before I started messing with them because the of the model mismatch (Phone now thinks it is a U01 version). And since there is no stock ROM for the U05 model to download, except for an UPDATE.APP from Movistar Mexico that phone refuses to accept, I'm afraid that if I reverse the whloe process I will end up with a bricked phone and no Stock ROM to bring it back.
Here comes the question. How do I force install a WRONG ROM into my phone? Remember: my Y330-U05 now thinks it is a Y330-U01.
Thanks a lot!

------------------------------------------------------------------------------------------------------------
I'm receiving an error message "SU inaccessible" after hitting the ROOT icon. The phone is a No.1 S7 MTK6589.
I previously tried using the Frameroot app but it failed as well.
Any ideas what the problem might be and how to solve?
Thanks,
Ruby

i saw your screenshot and yellow box at the bottom clearly indicates that your device has not been rooted properly. adb still exists as secure region. it is said that your device should said to be rooted properly only when your device got adb insecure. However, if your device has locked bootloader, doing so, i.e. entering or making adb insecure may lead your device to dead boot, a stage from which there are only two ways to survive from:- JTAG/RIFF box OR by replacing motherboard!!!!
However, if your bootloader is unlocked and only if your device is dev friendly, following link may help you to get green box at the bottom of MTK Droid Root Tools indicating your device has proper root access.
However, i have successfully solved this error in my panasonic p81 by making adb insecure.
Though, Do this on your own risk....Remember again, making adb insecure may make your device FAIL!!!!

Thanks to dev Chainfire again for this wonderful application....
I am not responsible for anything that happens in your life. Including what happens as result of following steps in this thread.
Hello all. After a long journey here, we figured a new thread would be in order for new comers not to have to read through fifty pages of information. Here you will find firmware to fix or update your Viking Pro. You will also find root methods, bootloader unlock and custom recoveries for this tablet. Lets start with ROOT...
Method 1: Kingroot. Kingroot works on this device. you can find it here. It's pretty straight forward, just download and install the apk and root.
Method 1.5: SuperSu. Kingroot works but it's not the best root out there. once you have root, follow the instructions here and Kingroot will be replaced with SuperSu.
Method 2: Su flash-able ZIP. This method requires you to follow steps in posts No. 3 and 4. Once you have custom recovery installed, You can flash This.
This method is a bit redundant. However, it does allow you to make a completely stock unooted backup of your rom before making any changes.
Check out posts 2, 3, 4 & 5 for the good stuff.
I'm gonna go ahead and thank everyone responsible and If I forgot to mention you, please don't hesitate to tell me and I will correct the situation:
@Bogram (Edited the bootloader so it could be unlocked on x.12.x versions)
@Jacube22 (Duplicated the method from Bogram to make the bootloader on x.9.x versions unlockable)
@vampirefo (Compiled a compatible CWM recovery for us)
@ewilley2008 (Found most of the firmware)
@mayzemay (Initial root thread)

FIRMWARE
There are two main branches of development for this tablet. It is very important to know which one you have because they are incompatible with each other. I personally bricked my first one with firmware from a x.9.x while mine is x.12.x. How do you check? Simple. In your build number, you can find it in "About tablet" in Settings or in the text at the top of the recovery screen. It's at the end of the number and it will look like 1.12.30, 10.12.20, 2.12.20, 1.9.1, 1.9.5, 10.9.1...etc The number in the middle is the important one.
Steps(Windows): For step 2 you will have five seconds. Preloader mode is only active for five seconds. So read first!
1- Extract the drivers to the destktop and open the device manager.
2- Plug your tablet in as such: turn off the tablet. Plug a male to male USB wire from the computer to the USB port on the tablet. now plug the power wire into the tablet. now very quickly in the device manager locate the new device and right click on it. select "update driver software" then select "browse my computer for driver software" and "browse". Now navigate to the driver folder, select the "CDC" folder and click on "OK" the "Next". The driver should install at this point. Once that is done, unplug the power cable from the tablet.
3- Extract the firmware and the sp flash tools to your desktop.
4- Start the sp flash tools and where it says scatter file loading click and navigate to the folder where you have the firmware and load the scatter file. You will see the firmware get loaded and a checksum check.
5- Once that is done, uncheck the preloader from the list and click on the download button.
6- Plug the power cable into your tablet. At this point the sp flash tool will load the firmware into the tablet. DO NOT UNPLUG ANYTHING UNTIL THE SP FLASH TOOLS SHOWS YOU A GREEN CHECK MARK TO INDICATE THAT IT IS DONE OR YOUR TABLET COULD BE HARD BRICKED AND UNREPAIRABLE.
7- Press the reset button and turn it on. Done!

Bootloader
So the bootloader on this tablet is locked. To unlock the bootloader, in a perfect world, you would usually boot the tablet in fastboot and type the command "fastboot oem unlock" and then follow the instructions on the screen. However RCA did not code in the volume keys in fastboot mode so it was impossible to unlock the bootloader that way. So our friend Bogram edited the bootloader and now the volume keys are not needed. What swell guy eh?
Unlocking your phone’s bootloader completely wipes (formats) your Android phone’s internal memory including applications, contacts, SMS and MMS messages etc.
So what you need is a scatter file like this one and a patched bootloader like these: x.12.x or x.9.x .
You will also need ADB & Fastboot and the drivers.
1- Just like in the FIRMWARE section, install drivers and SP Flash Tools.
2- Open SP Flash Tools and load the scatter file and in the line where you see "uboot" on the right click in the blank field and a window will pop up. select the patched bootloader. Make sure it checked and click on the "Download" button.
3- Now plug the male to male USB cable and then plug in the power. SP flash tool will flash the bootloader and then show you a nice little green check mark.
4- At this point you need to unpack the adb folder from the RAR file and place it in the root of you hard drive(C: ) then open a command prompt and nvigate to you adb folder (cd c:\adb) and leave it there for just a second.
5- On your tablet unplug the power wire, hit the reset button in the back and boot it into recovery mode by pressing and holding the volume up and power buttons together until the RCA splash screen comes up then release them.
6- In recovery, use the volume keys to navigate to "reboot to bootloader" and use the power button to select.
7- At this point your tablet will be in fastboot and your computer should detect it and install the driver. If not, the driver is in the "Android" folder in the driver files you extracted.
8- In your command prompt you left opened earlier, type "fastboot oem unlock".
9-Your tablet will do some magic, summon a demon, banish it to the depths of hell, reboot a couple of times and then it will have a unlocked bootloader.
10- Done. now you ca move on the next post and flash recovery.
Bogram also created a tool that patches the bootloader automatically should you have a different version we don't know about or what not...

RECOVERY
This section depends on a unlocked bootloader. If you did not unlock your bootloader in the previous post, do so before continuing to this one.
So what you need is a scatter file like this one and a recovery.
CWM + Carliv compiled by vampirefo: (x.9.x)Clockworkmod recovery (x.12.x)Clockworkmod recovery
TWRP V3.00 compiled by Neporood: (x.9.x)TWRP V3.00 recovery (x.12.x)TWRP V3.00 recovery(Coming soon)
- Open SP Flash tool and select the scatter file.
- in the recovery line, on the right side in the blank field, click and select your downloaded recovery.
- Click on the download button.
- Make sure your tablet is off, plug the USB cable first and then the power cable.
- SP Flash tool will flash the recovery and show you a lovely green check mark.
- Once that is done your recovery will be flashed.
** The stock system has a file in the system folder called "recovery-from-boot.p". this file flashes stock recovery randomly at boot so with a rooted system, navigate to the folder with a root capable explorer and delete the file so that your new recovery stays there.
** When rebooting from recovery, cwm will tell you to fix root. Don't. Select no every time.
For thos of you who want a file explorer in recovery, You can download this Aroma installer flashable
It's a nice tool to have...

Not yet but soon.....
I'd swear I've seen all this somewhere before... lol
Good job, brother!
Now , let the roms...begin.....
woot ... just in time as I brought my Viking Pro home from Wallyworld Saturday night.
Any thoughts on ADB? I couldn't make it all the way through the other thread and eventually just gave up.... ended up figuring out Kingroot on my own and then just enabled ADB over wifi. Would much rather have a wired ADB solution as moving an APK (I'm a developer, duh) over wifi can be somewhat s-l-o-w.
Any plans to make a thread like this for the RCA Maven Pro (RCT6213W87DK)? It'd be really swell.
EDIT: Actually, with those sources you posted, I actually might be able to do this on my own.

I've got a Maven, and I've already done the porting. I'll be posting a guide tomorrow morning sometime. For now, I've sent you a PM with links to the firmware. Check your firmware version, mine is V36-1.9.21 (as long as you have the "9", you should be ok) The zip file has everything in it, preloader, scatter, custom recovery, etc...
Maven Guide is up, find it here

I can't get the port(s) to light up under OSX. I've tried a couple build.prop changes, plugging in micro usb, usb type a, power connector, and various combinations but none of them appear to trigger registration of a usb device of any kind on the host machine.
I can't even get simple stuff like MTP to work.

Time is my issue but I'm looking at two things. there is a firmware package i found on the Chinese server for a tablet with the model number rct6603w47dk with the same board as the viking pro but with a 8163 instead of the 8127. i think its doable to port over to our tablet. it is android 6. also the maven pro(rct6213w87dk) which is really close to our tablet with the same board but a larger screen, has adb working on it...
You should be getting a reaction through the micro usb port... on windows it shows up as a malfunctioning device.
i get nothing when sniffing the USB bus on my MBP.

I does the same thing on Ubuntu 14.04, absolutely nothing shows with "lsusb" in the terminal, unless it's in fastboot mode. You can use fastboot to flash the device, if you don't have access to a Windows machine...

What version of Windows are you running..the difference is the drivers are signed or unsigned.. This matters more on newer versions of Windows.
SPECIAL KNO'DIS: This Guide has been changed to refelct proper installation for both types of Maven Pro tablets, be Sure to follow the appropriate guide.
For the purpose of this guide, I'll assume you already have working ADB and Fastboot on your PC, if not, you'll need to set that up first. This guide doesn't cover installation of ether of those. If you're looking for the guide to the Viking Pro (RCT6303W87DK), go here.
KNO'DIS: I, OR ANYONE ELSE AT XDA, WILL NOT BE HELD RESPONSIBLE FOR "BRICKING" YOUR TABLET!! IF YOU MANAGE TO MAKE A BRICK, DUE TO YOUR "FUN-DA-MENTAL" INABILITY TO READ, GO BUILD A BBQ PIT WITH IT!! (Or ask for help, there's a lot of friendly people around here)
So, without further ado, lets get started. First, you'll need to know which version of firmware your device is running, this can be found in 2 different ways. From a running device go to: Settings/About tablet and look at the Build number. Or you can boot into stock recovery and the firmware version will be at the top left of the screen.
You should see something like the following, and note the 2nd number after the 2nd "V":
Code:
RCT6213W87DK-ANDROID5.0-V37-V1.9.30 <-- This is x.9.x version of firmware
or
RCT6213W87DK-ANDROID5.0-V68-V1.12.30-B <-- This is x.12.x version of firmware
Now that you know which firmware you have, follow the approriate guide below. I've broken this post into 2 different sections, as each tablet is just a little bit different.
About the Bootloader
This applies to both versions of firmware and tablet users. Turns out, the booloader doesn't have to be unlocked in order to install a custom recovery or root the device. So there's really no reason to unlock it, and I have removed that portion of this guide.
Installing MTK Preloader Signed Drivers
Drivers located Here
x.9.x Versions
Steps (Windows 8/8.1/10): For step 2 you will have less than five seconds. Preloader mode is only active for a few seconds. So read first!
1- Extract the drivers to the Desktop and open the Device Manager ("right click" on the Start button, select "Device Manager")
2- Plug your tablet in as such: turn off the tablet. Plug in the micro USB on the tablet, the other to the USB port on the PC, now very quickly in the device manager locate the new device and right click on it. For me, it showed up under "Other devices" and read MT65XX.
3- Select "update driver software" then select "browse my computer for driver software" (make sure "Include subfolders" is selected.
4- Click "Browse..." and navigate to where you extracted the driver zip. You "should" be at the following path: Desktop/MTK Preloader Signed Drivers
5- Click on "OK" then "Next". The driver should install at this point. Once that is done, unplug the usb cable from the pc (I find it easier to just keep the micro in the tablet).
x.12.x Versions (Requires Full size Male-to-Male USB Cable)
Steps (Windows 8/8.1/10): For step 2 you will have less than five seconds. Preloader mode is only active for a few seconds. So read first!
1- Extract the drivers to the Desktop and open the Device Manager ("right click" on the Start button, select "Device Manager")
2- Plug your tablet in as such: turn off the tablet. Plug in the full size USB cable to both the tablet and the PC.
3- Plug the micro USB into the tablet, the other to another USB port on the PC, now very quickly in the device manager locate the new device and right click on it. For me, it showed up under "Other devices" and read MT65XX.
4- Select "update driver software" then select "browse my computer for driver software" (make sure "Include subfolders" is selected.
5- Click "Browse..." and navigate to where you extracted the driver zip. You "should" be at the following path: Desktop/MTK Preloader Signed Drivers
6- Click on "OK" then "Next". The driver should install at this point. Once that is done, unplug both USB cables from the PC (I find it easier to just keep them in the tablet).
Installing TWRP
Firmware/TWRP Downloads
Maven x.9.x (Currently Contains: V37-1.9.30 and TWRP)
Maven x.12.x (Currently Contains: V63-V1.12.0-20150802 and V66-1.12.20-B-20150831 Firmware and TWRP)
Special Thanks to: @ShadowCX11 for testing for me.
Be sure you are using the appropriate TWRP for your version of firmware, and do the following:
1- Extract the firmware and the SP Flash Tool to your desktop.
2- Start the SP Flash Tool, and where it says "scatter file loading" click and navigate to the folder where you have the firmware and load the scatter file (depending on device, it could be in the "Images" folder).
3- Once that is done, uncheck everything, and select "recovery" only, from the list, navigate to the TWRP image file and click "Open", then click on the download button.
4- Plug the USB cable(s)* back into your PC. At this point the flash tool will load the recovery to the tablet. DO NOT UNPLUG ANYTHING UNTIL THE FLASH TOOL SHOWS YOU A GREEN CHECK MARK TO INDICATE THAT IT IS DONE, OR YOUR TABLET COULD BE HARD BRICKED AND IRREPARABLE.
5- After you get your check mark, unplug and boot into recovery, hold the Volume + and Power button. When splash screen comes up (the 2 dogs) release the power button.
6- Welcome to TWRP
*Remember, x.12.x requires 2 USB cables to work
ROOT
You can get root by flashing the latest SuperSu zip file located here, be sure to download the flashable zip.
Otherwise, for root, you can use the KingRoot app located here, (get the apk, or "Download for Android") and if you don't want a Chinesse Super User app, you can replace it with the ChainFire SuperSu by going here.
NOTE: This method of replacing KingRoot with SuperSu no longer works properly, and results in a bricked device.

Hello! I've had my Maven Pro for a couple months now and I still haven't rooted it like I have with the rest of my devices. I'd love to do it too, but reviewing your instructions, I found that my version number is way different. V66-V1.12.20-B. will that version patch tool still work for it? is there an update that it's refusing to download? Thanks!
Edit: on top of this, i can't get it to even connect (step 2) with any of my microUSB cables. (they work with my other devices)

Ooh, a v12, sorry friend, lol. Make sure the tablet is off, and be ready with "Device Manager" open, the preloader only shows up for a bit, then it disappears. The patch tool should still work for you, but the TWRP recovery may not. If it doesn't, the CWM recovery will after I modify it, because it's non-touch.
If neither recovery works for you, you can give me a copy of your "boot.img" file, and I can convert TWRP or CWM to work on your tablet. Also, I've changed the guide up top to include other root methods.
If you have any trouble, by all mean, post, and I'll try to help you through it
Regards,
Nepo
EDIT:
A friend found some V12 firmware, and I'll be uploading it soon. I can get a boot.img file from it to make a recovery.

You can reflash firmware while it is in a bootloop, I've done this many times. If you have everything set up, drivers, SP Flash Tool, firmware, etc..
Do the following:
1) Startup the Flash Tool and Load your firmware, as described in the OP (be sure to "uncheck" the Preloader)
2) Plug in your micro USB cable to both the PC and the tablet
3) Press and hold the "Reset" button located on the back
4) Click the Download button, then let go of the reset button, it should start flashing the firmware.
If it doesn't the first time, retry steps 3 and 4. I've had it fail the first time before, but work on the second.
Good Luck and let me know how it goes. Also, if the battery is completely drained by the time you read this, just flash firmware normally (again, uncheck the preloader). The tablet has to be powered off to flash it anyway.
Regards
Nepo
So after reflashing my tablet (a Canadian V12 that had V68, and flashed to V66 trying to unlock the boot loader and install CWM), USB doesn't work. The port doesn't output any voltage, and neither does the keyboard connector. The tablet acts like nothing is there, as does the PS3 controller I tried. Also, before, Firmware Update would say there's no updated firmware. Now, it doesn't seem to do anything. I flashed every partition except preloader, MBR and ebr, and the sec partitions. Do I have to reflash again, or is there something else I can do?
On a completely different note, I tried flashing a patched lk.bin, and it failed with an error I don't remember (I had temporary access to a PC).
One more thing that was quite interesting to me. It seems if you reboot into recovery or bootloader from Android (APM+ or root), you're then able to access the recovery with Power + Vol. Up. Is this known, or was it a fluke?

No USB is a new one on me, I wish I had a x.12 version of this tablet to test on (mine's x.9) I'd try a re-flash, this time, do everything but the preloader, the reason for not flashing a preloader is because it sometimes semi-bricks one of these tablets.
Interesting note, there was a guy on the Viking thread (RCT6303W87DK) that flashed CWM without unlocking his bootloader, and everything is working fine for him...

Nepo
PS, Power + Vol Up is the standard way to enter recovery on this device (I have the Xposed APM+ apk installed too)

So just a quick question: Is the device /dev/recovery for sure recovery? I want to see if I can just use dd to flash recovery.

Yes, to pull a copy from a running tablet you use dd, and the path is: /dev/recovery
So, I'd do it this way, using adb:
Code:
adb push NAME_OF_RECOVERY.img /data/local/tmp
# Wait for it, then type:
adb shell
#Followed by:
dd if=/data/local/tmp/NAME_OF_RECOVERY.img of=/dev/recovery
#After it finishes:
reboot recovery
Okay, I got CWM installed! Now to see if I can find a way to build TWRP...

Great! Is the CWM in portrait or landscape? You can always try to port the one I built for the x.9's, just unpack stock recovery, unpack TWRP, swap out the prebuilt kernel and repack.

It's in landscape, and works quite well! I just like the touch interface a bit more. I'll try the kernel replacement.

I prefer TWRP as well, that's why I built it
The only reason I don't have one posted for x.12 users is I can't test it. If you get it to work properly, let me know and I'll add it to the OP so others can benefit. :good:
If not, I can do some builds for you to test, if you don't mind. I have the x.12 kernel in my repo

Yeah, I can't figure out how to extract the kernel, because I don't usually have access to a PC. However, I'll take some testing builds if you can make them.
Also, back to the USB issue, a reflash of everything except preloader didn't fix it. However, checking the firmware update now tells me that this is the latest version (which is definitely wrong, since I had v68). It must be an incompatibility between the USA and Canadian variants. If you find a Canadian firm dump, can you send me a link?

Hmm, okay.
So I just took a look at the model number on my box, and it's RCT5213W87DKF. That extra letter is what changes this a bit. I'll try seeing what I can dig up in terms of OTA updates, and I'll keep posting about what I find.
---
Okay, so after a few packet captures, I found the tablet makes a GET request to http://tablet12.gyrodock.com:2300/OtaUpdater/android?device=RCT6213W87DK with the User-Agent rk29sdk/4.0, but the server returns a 404 page. When I do this in the browser, however, I get something quite peculiar happen, which interests me. Most of the other places on the site return a Tomcat 404 that has the path in the parenthesis. However, for the OTA URL, it just has empty parenthesis. POST requests to that URL return a 200 OK with no return data, which is also interesting. I'll keep hunting around.
Some people might not have a PC to run flash_tool on, so here's how you can flash recovery/uboot/mbr/ebr2/logo/sec_ro from within Android
I'll use recovery as an example. I'm using a V12 tablet, so steps might be different if you have a V9. I tried to make this guide as revision-agnostic as possible, so correct me if I mess something up.
Root your device. The method I use is KingRoot, because it doesn't require any weird things. You can uninstall KingRoot and flash SuperSU later.
Download a recovery image. Make sure if you have a V12 tablet, you download a recovery image for V12, and a V9 recovery for a V9 tablet, or you'll brick your recovery. I personally prefer TWRP, because it has more features and a nicer UI, but CWM works too.
Get shell access. You can use a terminal emulator.
Type in su, and give the terminal superuser access on your device.
Type in dd if=/sdcard/Download/mavenVY_XXX.img of=/dev/recovery, where Y is 9 or 12, and XXX is CWM or twrp3.0.2. This will flash the recovery image.
Finally, type in reboot recovery. This should reboot into your custom recovery! It might also enable Power + Vol Up access to recovery, however, this hasn't been confirmed.
All the other partitions are similar, just replace the references to recovery images with the respective file names for the raw partition, and /dev/recovery with /dev/[PARTITION]. You can NOT flash the android or usrdata partition while in Android or you'll most likely soft-brick your tablet, however, you can boot into TWRP and go to the terminal and do the flash. You must copy your disk images to /tmp when doing so however, or you'll probably lose the disk image during the flash, effectively causing a brick.
Hope this helps people out!

I've found out that it seems the v12 tablets strictly enforce the checksums of partition images, so flashing a custom recovery or uboot does not work with flashtool.

Nice addition, but all you have to do is disable it in the Checksum.ini file (change the 1 to 0):
Code:
[IsEnableChecksum]
CHECKSUM_SWITCH=0
I did that for the v9 versions, but only uploaded the v12 firmware...

Hello Everyone. This is my first post on XDA-Developers, and I want to share my experience on how I transferred my Huawei G750-U10 to Android 4.4.2. For the people not interested in my experience, and are only here for the explanation, scroll down to the tutorial part.
Story part (my experience)
First off, I did some research on how to root the phone, because you will need a rooted phone to install other firmware and custom ROMS. Rooting is essentially unlocking an account on your phone that has access to all the files and programs so that you can have more control over your phone (it is normally disabled for security reasons). Rooting the phone was easy. I used a program called RootGenius, which is just a 1 click-root program. Very handy and easy. After this, the hard part started.
Fyi, the only reason that I started this project is because I wanted to play Pokémon GO w/o buying a new device
From this step I did a full backup of my current ROM and NVRAM and wrote down my IMEI numbers (the G750 has 2 IMEI numbers because it has 2 SIM-Card slots). These numbers are unique for your phone and are used for calling and sending SMS messages. So make sure you write them down (in my phone they were also written down under the battery). The program I used to backup the NVRAM and the IMEI numbers is MTKDroidTools.
After this step, I tried unlocking my bootloader. But it was very stubborn (I was using the latest firmware from Huawei, B119) and I tried doing this with fastboot. Which failed every single time and gave a 0x7000 error when I tried to unlock the bootloader. But I have to say that my bootloader was acting weird from the start anyway. Whenever I used the command:
Code:
fastboot oem device-info
It always showed that the bootloader was unlocked, eventhough after I locked it using the command:
Code:
fastboot oem lock
Which is weird. So I will just include a tutorial on how to unlock the bootloader just in case yours works normal.
So, after realising that my bootloader was not working correctly, and I could not install any recovery mod like CWM or TWRP (or any custom ROM for that matter), I found out that I needed to flash to the chip directly. This was also a huge challange, since i've never done this before and I actually did not know what I was doing. I've changed ROMS on phones a couple of times before, but that always was with a unlocked bootloader and so via the "normal" recovery system way.
For this part, I used XDA user: jacktackles' post a lot. He had some handy information about flashing to the chipset immediately and on what files to use. Since my B119 firmware was locked, I first wanted firmware with an unlocked bootloader. So I flashed some Chinese G750 firmware, that changed my device from a G750-U10 to a G750-T00. The flashing process was not flawless at all, and was the part that took me the most time (10+ hours). This all because I forgot to untick 1 simple box... Oh well, I guess that is how it works (at least I got it to work ). So, after flashing this Chinese firmware, the hardest part was done. And I had access to TWRP Recovery. With this I installed the custom ROM that I wanted, and that is where my adventure ended.
So, to summarize: It is not easy, and not beginner friendly. That is why I wanted to make this post: To make it easier for you guys to do the same and get to catch YOUR Pokémon! (Or just to upgrade to 4.4.2). So let's now go to the tutorial part!
Tutorial part
I did this with a Windows 10 64-bit computer, although I would recommend using Windows 7. You will also need a usb-cable to connect your phone to your computer. Make sure that everytime you install a new ROM that you re-enable USB-debugging. You do this by going to your phone options > About Phone > Click "build number" 7 times > Go back to options > Developers options and tick the USB-Debugging tickbox.
Sorry for not uploading screenshots, but XDA prevents me from using any outside links because I'm a new user (so i'll try to be as precise as possible). This means that also any downloadable files should be retrieved from jacktackles' post (again big thanks to him!). His forum post can be found here: http://forum.xda-developers.com/android/general/huawei-g750-u10-honor-3x-kitkat-4-4-2-t3038166.
So, go to his post and download the VCOM drivers, MKT Droid Tools, B113 4.2.2 base with unlocked bootloader, Root Genius, and this ROM from another XDA-Developer: http://forum.xda-developers.com/showthread.php?p=62356379#post62356379 (Thanks a lot mate! Awesome upload). The Gaaps link is not needed with my method, and the last link is down. So you will need to get a replacement ROM for that. I used one from NeedRom. Just go to their site, and search for G750-U10 and download a ROM that you want (which is Android 4.4.2 of course). Or download another rom from any other site. The one I used is called: G750-U10 KitKat which was listed on the site on: 07/22/2015 11:35 pm. But you can also choose to download another ROM.
So to sum up, we got 3 ROMS:
1. The Chinese Firmware downgrade to B113
(FILENAME: G750-U10 V100R001C00B113CUSTC432D001_Firmware_Slovakia_Austria_Lithuania_Czech Republic_Latvia_Estonia_Greece_05021NHU)
2. The ROM from pavel22 to change the device to G750-T00
(FILENAME: G750-T00_mod8_265_FlashTool)
3. The ROM that we finally are after
(FILENAME: Huawei G750 U10 Kit Kat 4.9.16)
(In my case of course, not if you downloaded another "final" ROM)
Okay, so after all the files are downloaded and extracted (except for the 3rd ROM), we can start!
1. Rooting
This step is very simple and quick. Plug in your phone to your PC and open Root Genius. Click the big button and your phone should be rooted. If it gives an error, just try again and again until it works. After this restart your phone, and a new app "RootKing" should be installed. If not, the phone is not rooted.
2. MTK Droid Tools (backing up NVRam & IMEI)
Extract MTK Droid Tools from it's ZIP file, and place it in a folder. Now extract the VCOM drivers and install them. These drivers make MTK Droid Tools recognize your device. After installing the drivers, open up the .exe file from MTK and make sure it recognizes your device. If it does not, reboot your PC and try again. After your device is recognized, install the "adbd insecure" app on your device, from the playstore (or download it somewhere else if you do not want to pay). But trust me, it is worth the money. Once adbd is installed, tick both boxes on the app, so that we can connect to your phone with MTK. If done correctly, MTK Droid Tools should now be able to get full access to your device, and a green box will appear in the left bottom of the program.
Now, backup your NVRam and IMEI. You do this by clicking on the "IMEI/NVRAM" button, and clicking backup. To be safe and for ease of access, write down your IMEI's on a paper or notepad file. Now the real fun starts!
2.5 Unlocking the bootloader (you might not have to do this)
Only do this step if you get a BROM error with code 6045 when trying to flash any roms. Here is how you unlock the bootloader:
1. Install ADB drivers. I used a tool made by XDA user Snoop05 (http://forum.xda-developers.com/showthread.php?p=48915118)
2. Connect your device to your pc
3. Open up a command promt from windows
4. type "adb" and check if it returns a big list of available commands (that you know for sure that adb is installed)
5. Type "fastboot" and check if it returns a big list, for the same reason
6. Now type "adb devices" and check if it gives your device, if not make sure you have correct usb drivers installed for the G750-U10, if not just install HiSuite from Huawei (It comes with the correct drivers), then disconnect your device and type "adb devices" again.
7. Now type "adb reboot-bootloader" and your phone will restart in fastboot mode.
8. Type "fastboot oem unlock" and follow the instructions on your phone screen (they are very small and hard to read).
3. Flashing the Chinese Firmware
In the Chinese firmware folder, there will be 4 sub-folders: SD_Upgrade, Update Tool, USB_DRV, USB_Upgrade.
0. Delete the SD_Upgrade folder (Not needed).
1. Go to USB_DRV and install the .exe file in the: "Driver For servers 2012-11-27" rar file.
2. After this open the Update Tool folder and extract files.
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file.
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
4. Flashing the: "G750-U10 to G750-T00" Firmware
This will be almost the same as part 3.
Extract the "G750-T00_mod8_265_FlashTool" rar file, and:
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file (make sure that you select the scatter file from the new rar file, and that you are not using the same one as before).
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
5. Restoring your NVRam and IMEI
You might need to root your device again, check if need be, by searching for an app called SuperSU or RootKing. If they are not present, root the device again with Root Genius.
You will need to re-install the "adbd" app on your new ROM. If there is no Play Store present, search for a Play Store APK on Google. Once, installed check the 2 tickboxes and re-open MTK Droid Tools.
Click on the "IMEI/NVRAM" button restore your backed-up NVRAM and retype you IMEI codes. Once the restores are done, restart the phone and check if you can call someone. If it works, good job! You can now progress to the very last step! If not, check if you entered the IMEI correct. You probably made a Typo.
6. Installing final ROM
Now that you have installed pavel22's ROM, you have access to a recovery system. So copy the whole 3rd zip file to the root folder of you device. Turn off your device, and turn it on again but this time while holding both volume buttons and the power button until TWRP opens. Click on install, search your zip file and swipe right. When it finishes, do a factory reset from TWRP and then reboot the system normally. You should now have a fully working G750-U10 with Android 4.4.2. Congratulations!
This was my tutorial and personal experience with converting my G750-U10 to Android 4.4.2. It has been a wild ride, and i've reached points that I wanted to throw my device against the wall. I'm now very happy with my (feeling like) new device. I can now finally catch 'em all and become the best PokéMaster ever!
~ NeusAap.
Thank you for the tutorial. I know nothing about flashing.
However, I could follow the instruction until 4. Flashing the: "G750-U10 to G750-T00" Firmware.
The problem is that after I had clicked the "Download" button, and connected my device, the error popped up BROM ERROR : S_SECURITY_SECURE_USB_DL_IMAGE_SIGN_HEADER_NOT_FOUND (6045).
Could you please help? Thank you.

That error means that your bootloader must be locked. For me, it was acting weird. They way you want to (try) to unlock the bootloader is as follows:
1. Install ADB drivers. I used a tool made by XDA user Snoop05 (http://forum.xda-developers.com/showthread.php?p=48915118)
2. Connect your device to your pc
3. Open up a command promt from windows
4. type "adb" and check if it returns a big list of available commands (that you know for sure that adb is installed)
5. Type "fastboot" and check if it returns a big list, for the same reason
6. Now type "adb devices" and check if it gives your device, if not make sure you have correct usb drivers installed for the G750-U10, if not just install HiSuite from Huawei (It comes with the correct drivers), then disconnect your device and type "adb devices" again.
7. Now type "adb reboot-bootloader" and your phone will restart in fastboot mode.
8. Type "fastboot oem unlock" and follow the instructions on your phone screen (they are very small and hard to read).
If your bootloader is now unlocked, you should try to flash again. My phone gave an error at the step 9, but I still followed these 9 steps. So the error I got could also have been a visual programming error, or bug.
I hope this helps! Keep me up to date

Same error. I tried several times with "fastboot oem unlock" but it didn't work: err 0x7000. I could't find anything helpful on the internet.
The odd thing is when i typed "fastboot getinfo-bootloader" I got "(bootloader) unlocked".
I just wanted to be a pokemon trainer too

That was the excact same error I was getting. Also the same deal with the oem get-bootinfo thingy. Are you sure that while flashing you have unticked the "preloader" and the "usrdata" sectors? That is what did it for me honestly

Alright, then skip step 3 and go to step 4. I might have screwed up the step orders (It's hard to remember in what order I did all the steps ) if that works, i'll change the OP. I'm dorry if thats the case.

Yes, flash the g750-t00 one, and then the rom that you want if that worked. I think that I might have skipped that whole firmware downgrage rom
Thank you for answering
I tried what you had told me to do, but when I typed "fastboot oem unlock", the phone told me to use Volume Up/Down button. I used "Volume Up" button to unlock bootloader but it failed - err 0x7000 same as Iroh96, I guess. So I typed "fastboot getinfo-bootloader"; however, I got "waiting for device" instead of "(bootloader) unlocked". Then, I tried step 4 but it was still an error 6045. I don't know what to do next.
Why is it so hard to be a pokemon trainer?
hi, i couldn't download the:
"Rooted with twrp recovery inbuild base rom"
because the link is not available.
is this really necessary?
if yes, can you give me another link to download it?
i wanna start follow the steps but first i need all the downloads
Inquiries
I already read and downloaded all files which included in jacktackles thread.. I even read the whole posts
My point of view is, im kinda a noob to root business and afraid to end up by destroying my device especially when I contacted an Egyptian -who had already converted his phone- and he didn't recommend to do this.. so please bare with me.
*first of all is the deal link for "Rooted with twrp recovery inbuild base rom" is this really necessary?
*2nd point is my phones build, its B116. Can I proceed converting my phone or it won't work?
Thanks in advance
FOR THOSE WHO ARE HAVING TROUBLE UNLOCKING THE BOOTLOADER:
I found this post from Pavel22

Good luck! I successfully converted my Huawei G750-U10 to G750-T00. Now, I'm on Kitkat 4.4.2. Thanks for this in-depth tutorial, btw. Was really a great help.

1. Rooting
This step is very simple and quick. Plug in your phone to your PC and open Root Genius. Click the big button and your phone should be rooted. If it gives an error, just try again and again until it works. After this restart your phone, and a new app "RootKing" should be installed. If not, the phone is not rooted.
2. MTK Droid Tools (backing up NVRam & IMEI)
Extract MTK Droid Tools from it's ZIP file, and place it in a folder. Now extract the VCOM drivers and install them. These drivers make MTK Droid Tools recognize your device. After installing the drivers, open up the .exe file from MTK and make sure it recognizes your device. If it does not, reboot your PC and try again. After your device is recognized, install the "adbd insecure" app on your device, from the playstore (or download it somewhere else if you do not want to pay). But trust me, it is worth the money. Once adbd is installed, tick both boxes on the app, so that we can connect to your phone with MTK. If done correctly, MTK Droid Tools should now be able to get full access to your device, and a green box will appear in the left bottom of the program.
Now, backup your NVRam and IMEI. You do this by clicking on the "IMEI/NVRAM" button, and clicking backup. To be safe and for ease of access, write down your IMEI's on a paper or notepad file. Now the real fun starts!
2.5 Unlocking the bootloader (you might not have to do this)
Only do this step if you get a BROM error with code 6045 when trying to flash any roms. Here is how you unlock the bootloader:
1. Install ADB drivers. I used a tool made by XDA user Snoop05 (http://forum.xda-developers.com/showthread.php?p=48915118)
2. Connect your device to your pc
3. Open up a command promt from windows
4. type "adb" and check if it returns a big list of available commands (that you know for sure that adb is installed)
5. Type "fastboot" and check if it returns a big list, for the same reason
6. Now type "adb devices" and check if it gives your device, if not make sure you have correct usb drivers installed for the G750-U10, if not just install HiSuite from Huawei (It comes with the correct drivers), then disconnect your device and type "adb devices" again.
7. Now type "adb reboot-bootloader" and your phone will restart in fastboot mode.
8. Type "fastboot oem unlock" and follow the instructions on your phone screen (they are very small and hard to read).
3. Flashing the Chinese Firmware
In the Chinese firmware folder, there will be 4 sub-folders: SD_Upgrade, Update Tool, USB_DRV, USB_Upgrade.
0. Delete the SD_Upgrade folder (Not needed).
1. Go to USB_DRV and install the .exe file in the: "Driver For servers 2012-11-27" rar file.
2. After this open the Update Tool folder and extract files.
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file.
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
4. Flashing the: "G750-U10 to G750-T00" Firmware
This will be almost the same as part 3.
Extract the "G750-T00_mod8_265_FlashTool" rar file, and:
3. Open the flash_tool.exe file, which is used to flash the device (like the name suggests )
4. Once the program is open, click on the "scatter-loading" button. Search for the USB_Upgrade folder, and select the MT6592_Android_scatter.txt file (make sure that you select the scatter file from the new rar file, and that you are not using the same one as before).
5. Turn off your device, remove the battery, wait a few seconds and reinsert the battery back into the device. Do NOT turn on the device.
6. Make sure SP_Flash_Tool is set to "Download only" (can be set by the dropdown box)
7. Click the "Download" button, and connect your device to your PC.
8. Wait, and the progress bar will fill up. DO NOT DISCONNECT YOUR DEVICE OR YOU COULD BRICK IT!
9. Success? Great! Restart the phone and progress to the next step!
10. Failure? Untick the Preloader partition and repeat from step 5. Still not working? Also untick USRDATA and try again.
5. Restoring your NVRam and IMEI
You might need to root your device again, check if need be, by searching for an app called SuperSU or RootKing. If they are not present, root the device again with Root Genius.
You will need to re-install the "adbd" app on your new ROM. If there is no Play Store present, search for a Play Store APK on Google. Once, installed check the 2 tickboxes and re-open MTK Droid Tools.
Click on the "IMEI/NVRAM" button restore your backed-up NVRAM and retype you IMEI codes. Once the restores are done, restart the phone and check if you can call someone. If it works, good job! You can now progress to the very last step! If not, check if you entered the IMEI correct. You probably made a Typo.
6. Installing final ROM
Now that you have installed pavel22's ROM, you have access to a recovery system. So copy the whole 3rd zip file to the root folder of you device. Turn off your device, and turn it on again but this time while holding both volume buttons and the power button until TWRP opens. Click on install, search your zip file and swipe right. When it finishes, do a factory reset from TWRP and then reboot the system normally. You should now have a fully working G750-U10 with Android 4.4.2. Congratulations!
This was my tutorial and personal experience with converting my G750-U10 to Android 4.4.2. It has been a wild ride, and i've reached points that I wanted to throw my device against the wall. I'm now very happy with my (feeling like) new device. I can now finally catch 'em all and become the best PokéMaster ever!

I can't download the KitKat rom from needrom.is there any other link?????
Hi mates! I'm stuck in the bootloader unlock step; it keeps showing the 0x7000 error and it doesn't let me flash anything with the SP Flash Tool (guess it's because of the 0x7000 error). I tried to follow the Pavel22 guide posted up there... i can flash the rework-secro succesfully, but i get the 4008 error when flashing the whole rom. Can someone help me? Thanks!!
