REQUIREMENTS:
* Android SDK with ADB (guess you have this, if not, main files are included in permaroot.zip attached below)
* RockChip RK3066 USB Driver (see attachments below)
* Root/UnRoot script (thanks to Bin4ry from this thread, see attachments below)
* Micro USB Cable to connect Tablet and Windows Desktop PC (Linux is unsupported for now due to manufacturer limited driver distribution)
WARNINGS
1. Using this tutorial will make firmware/software changes on your device(s) but I am not responsible for any damage it could cause.
2. Following steps below will probably VOID YOUR WARRANTY. Read carefully your reseller warranty terms and conditions, and make your decision. It is all up to you.
3. I am not obligated to respond to future questions and/or support, it is my time and good will. If you must, ask here in this thread, there is no need to send me private messages to me because i wont read them at all.
4. You will spot that i dont recommend making any nand backups in this howto - is because I am not aware of any working method for backup M-12. I onlu can imagine dumping whole partition images to your EXTERNAL_SD and flashing back through bootloader but I did not tested that for now.
#GET ROOT
STEP-BY-STEP HOWTO
1. On your tablet PC go Settings -> Developer Options -> Turn on USB Debugging
2. Now You need to manage your Android Debug Bridge recognize your Tablet PC. You can check if it already works by typing this command in command prompt (in ADB folder, or wherever if you extracted adb into windows/system32)
Code:
adb devices
It should give you list of attached devices (something like this: 0123456789ABCDEF device) you should recognize your device if is connected. From my experiences it wont work the way manufacturer described, therefore you need to install patched RK3066 SoC driver you downloaded (this post below). To do so you must right click on My Computer -> Manage -> Device Manager, find your Unknown Device and install driver manually by selecting search folder manually, where you extracted RK3066_ADB_PATCHED.rar content respectively to your OS version (use correct 32-bit or 64-bit driver). Reboot your PC, go to device manager to check if Android Debug Bridge is there:
And You can repeat "adb devices" once again in adb to verify:
3. Now is time to obtain temporary root. To do so, simply navigate command prompt to wherever You extracted adb.exe and type following command:
Code:
adb remount
It uses common JB exploit, which exists in BlueBerry NetCat M-12, alowing you to get temporary root access via ADB shell until next reboot. You can stop at this point and push any system file You want (ie /system/etc/hosts) and set permissions. But if you want permanently rooted device, you need to push SuperSU.apk, su, busybox,... manually via adb before next reboot. Lucky for you, there is a script (permaroot.zip thanks to Bin4ry) which can do it all automatic with just few clicks. Download it from attachment below, extract somewhere on your hard drive run permaroot.bat and have fun.

++ Illustrated Hardware disassembly guide ++
++ There is one custom ROM ported for another device and tested by me, which works in M-12 like a charm. It is purified JB ROM, rooted and without bloatware. I will post it ASAP ++
++ If i be able to obtain original Blueberry firmware dump, i will make CWM Touch based recovery image. Any interested owner of original BlueBerry NetCat should supply me with F/W dump, so if you are one, PM me please ++
++ If I be able to make Cube CWM Touch recovery work I will share (I managed to extract and install it from supersport900 ROM but it wont mount partitions for some reason) ++

+++ClockWorkMod based recovery image for BlueBerry NetCat M-12+++
CWM Touch 6.0.2.7 (Thanks to Typhoon.X)
CWM Touch is Direct-Touch-Input CWM Recovery image: you can use touch gestures to navigate through menus, but I still prefer old-fashioned way of navigating through menus by using Volume +/- for <UP> and <DOWN>, and Power button as <CONFIRM> which is also available on our devices.
WARNINGS
1. Using this tutorial will make firmware/software changes on your device(s) but I am not responsible for any damage it could cause.
2. Following steps below will probably VOID YOUR WARRANTY. Read carefully your reseller warranty terms and conditions, and make your decision. It is all up to you.
3. I am not obligated to respond to future questions and/or support, it is my time and good will. If you must, ask here in this thread, there is no need to send me private messages to me because i wont read them at all.
4. You are welcome to make backup(s) before make any change to your device; You can export partition(s) dump or make nandroid backup via CWM based recovery image if you have it allrady installed.
Install:
1. Make sure you have installed RK3066 drivers;
2. Download ClockWorkMod.zip, extract, run RKAndroidTool.exe.
3. Reboot your BlueBerry NetCat M-12 in Flash Mode (turn on device by holding Volume- and Power Button or push "Reboot to Flash Mode" button in RKTool)
4. Push "Flash ROM" button like on image below (all settings are stored in config.cfg so You dont need to change anything):
After procedure is finished (cca 15 seconds), device will be automatically rebooted into CWM Recovery, so it's highly recommended making first nandroid backup.
Usage:
If your device is rooted, you can reboot your device into CWM recovery by typing following commands in terminal emulator:
Code:
su
reboot recovery
Or by using any 3rd party rebooting widget/app, which allows rebooting into recovery.
However, if your device is not-rooted, you can reboot into CWM recovery by typing following commands which exploit temporary root access via Android Debug Bridge (adb.exe on your PC, drivers must be installed):
Code:
adb.exe reboot recovery
or
Code:
adb remount
adb shell
su
reboot recovery
Download CWM Touch based recovery image from Google Drive: ClockWorkMod or attachment below.
Be aware that bootsplash will be changed as you need to replace misc.img, so dont panic if you see Cube logo instead of NetCat.

Hey, CyberianIce, thank you for your contribution for this device, since it's really hard to find anything verified out there, and xda is alwas the safest choice.
I wanted to ask you if you could share the info, or link maybe, to that ported ROM you tested on Blueberry, since I don't wont to brick my device by trying an untested ROM.
Thanks in advance!

I can re-upload from my HDD because I forgot original URL, when I got day off my work.
/CyberianIce via TapaTalk HD

That would be amazing, thank you! And if you could write something about the ROM (when you have free time, of course) just so that I know what I'm installing..

Hi, i wonder how to make a hard reset on this devices, i have tried the normal way, volume(-)(+) + power but nothing is working. Can someone help me? Thanks!!

Hi, CyberianIce, I was wondering if you'll have time soon to upload the ROM, if it's not too much trouble. Thank you!

So far I found this Firmware image working best on NetCat M-12: http://www.rockchipfirmware.com/sites/default/files/cube_u30gt-h_V1.11_TNT_R1.zip
For Flashing use this tool: http://www.rockchipfirmware.com/sites/default/files/RKBatchTool1.5en.zip
(Credits: http://www.rockchipfirmware.com/)
It is great because you can flash it vie Rockchip Batch Tool which means its very useful for debricking. It is 4.1.1 from Cube U30GT-H with all this tweaks:
Brief Description:
-Rooted
-Based on stock rom (2012.12.28)
-App partition is Larger
-Build.prop mod based on SGS II SGH-i777 for improved market
-Added Permission Files for improved market
-Removed Chinese Apps
-framework.jar mod for better gameloft compatibility (Asphalt 7 should now work)
-Added SuperSu, gallery with picasa support, ESfile Explorer, english dictionary fix
-Simplified and pretty boot animation
-Changed Annoying Keyboard Key-press sounds... now they are less annoying (based off Cyanogen sounds)
-Default Background should be changed
-Changed "browser" start page to our Google paid search. Use it (free to use for you) to search the web and you will be helping to support us as we release more free firmware. Can easily change this if you want.

Afterwards one can flash CWM based recovery image following tutorial from this post

[ROM][RK3066][U30GT-H]BlueBerry NetCat M12
Based on latest original Cube U30GT-H ROM debranded from BlueBerry NetCat M12
Tested on many CUBE U30GT-H devices
Debloated
Removed China
Custom tuned Kernel for optimum performance and stability (up to 15k points in AnTuTu Benchmark)
Increased /data partition size to 2GB instead of 1GB (reduced internal sdcard partition to 12.5GB instead of 13.5GB)
NetCat BootSplash
Custom android bootanimation.zip
Fully working CWM Recovery 6.0.2.7
HOWTO:
1. Shut down your tablet and start it by holding down Volume + button and insert USB Cable with PC. RK Device will apear, if you have no drivers you can find them in archive.
2. Navigate to RKDevelopTool_v1.35 folder and run RKAndroidTool.exe
3. Click Erase IDB and wait for finish
4. Click Run and wait for finish
5. After procedure is complete, if your tablet don't start automatically in CWM, remove USB and shut down tablet by holding POWER button for 8 seconds (you will hear silent *click* sound from tablet as signal it's off). Now download CWM Base from this XDA post put tablet in download mode (VOL+ and USB CABLE) and flash this recovery (run RKAndroidTool.exe, push Flash ROM button). It is very same recovery from this ROM, but after this flashing is finished, tablet will boot into CWM automatically on it's own.
6. Now install ZIP files from after_install folder via CWM recovery. Format NAND is required if you first time using 2GB Data mod, and int2ext is required for some devices which reported switch between internal and external SD card. You must use an external SD Card for flashing ZIPs and search for files in both internal and external sd card in CWM as you still dont know how CMW see your SD card.
7. Reboot System. All done!
DOWNLOAD
Note: If you are used increase /data to 2GB MOD before, you can just install this firmware via RKAndroidTool. If your /data partition was 1GB before, you may need to install patches from folder after_install via CWM recovery.

This is a good budget device when compared to other devices from lead manufacturers like Samsung, Sony, LG or Huawei.
While searching on the internet I did find some Root & CWM installation methods.
I will be updating the relevant posts as and when needed.
You can look in the list below for what you want to do with your device.
ATTENTION!!! READ THIS BEFORE DOING ANYTHING
---------------------------------------------------------------------------------
Friend, there are two versions of this device in the market:
1. A706 (Chinese model)
2. A706_ROW (International Model)
The ROMs in this thread are only for the A706ROW model of this phone unless otherwise stated.
If you have the chinese model or another model A760 (which is a different model) then the ROMs in this thread are not for you.
Model A706 and A760 are two different models with almost same specifications. This DOES NOT mean that the ROMs of A706ROW are compatible with A760.
Please DO NOT confuse Lenovo A706 with Lenovo A760 as these are two different devices!!! Flash or experiment at your own risk!!!!
If you share a ROM link for any of the above devices, then please mention clearly the device for which the ROM can be used.
What to do with your Device ?

And, If you still feel it is worth the effort, proceed with caution!
FOR NOOBS
--------------------
Read the instructions (click on SHOW to read) before attempting anything from the list below!
First you need to have the Android SDK installed on your computer. Or atleast you need to have the adb & fastboot files available on your computer.
Here's a good post that tells you how to setup ADB and fastboot.
Here's a post that has a list of adb/shell commands for noobs.
Ok, once you are done with the setup of ADB & fastboot on your computer, then you can proceed with the below instructions.

IMPORTANT NOTE BEFORE FLASHING:
-------------------------------------------------------------
Recently, I have noticed that many people after buying the phone are flashing any firmware to their phones and most of the time without checking the phone versions and the OS versions. In the stock firmware post, I had mentioned that people having the Chinese version of the phone should NOT flash the ROW (international) firmware otherwise it would mess up their phone and network etc.
SOLUTION FOR SIM ERROR & DOWNGRADING TO CHINESE ROM
-----------------------------------------------------------------------------------------------------
Now, some of the people have already done such a mistake and for those people (who are having SIM or network problems and want to go back to chinese ROM, I am sticking this post by danyno1 to the OP:

CWM Installation Instructions:
-------------------------------------------
Make sure you have all the drivers for your phone installed on your computer. Download for A706 from here. Some other Qualcomm drivers (not sure if required)
Make sure you have USB Debugging enabled, Install from Unknown Sources is enabled and device is detected in ADB run this command:
Code:
adb devices
Download the CWM Recovery for A706 from here.
Unzip the downloaded file to get a "recovery.img" recovery image file.
Press SHIFT key + Right mouse click in the folder where the file is located and select Open Command from Here.
Now, in the command prompt do the following:
a. Reboot into Bootloader mode. Use command:
Code:
adb reboot bootloader
b. Device will reboot and display Lenovo logo. (check if device is in bootloader mode by running command:
Code:
fastboot devices
. If you see a device connected then you have successfully rebooted into fastboot mode.
c. Now, run this command:
Code:
fastboot flash recovery recovery.img
(This will flash the CWM recovery image to the device).
d. Once successful, reboot the device using this command:
Code:
fastboot reboot
. Or, you can keep the power+vol up+ vol down buttons pressed to restart.​
If everything has gone well, this should get CWM installed on your device. Your device is still *not rooted*. Once you have installed CWM, please proceed to the ROOT instructions post to *root* your device.

On the root of the memory card, create a folder called "sdfuse".
Unzip the downloaded firmware, you will get a QSB file.
Copy the QSB file to the sdfuse folder that we created earlier on the root of SD card.
Note: Please make sure that your phone has atleast 60% power before attempting or beginning upgrade. Or keep charger connected during the process.
SD card upgrade process:
Long press VOL UP + POWER_KEY to enter the droidboot,
A menu will appear. Select the fourth option, SDUPDATE.
At the bottom of the screen, you can see the progress and status of the update
When you see the message "SDCARD UPDATE SUCCESS!!!", this means you successfully completed the upgrade process
Now, reboot your device and hopefully it should be updated.
That's it! If you guys have found any more firmware download links (even for different regions, build etc.) just share them with me along with details and I will add them to the list in this post.

scuderialoki, unfortunate that you got stuck. worked for me without any issues. i upped the same file that i used on mediafire. can you re-download the file and then check if the file is ok by extracting the zip using winrar or winzip? if it is ok then try flashing it again.

guliboy123, i will be putting the link and some instructions on the stock rom post soon. bear with me as i have to check the instructions from the russian/chinese sites and then put it up here. in the meantime, i suggest you take a backup of your current ROM (which is stock) using CWM and then try out the QNeon-Modern ROM. remember u need to flash that ROM using CWM.

gr8techie thanks for the reply. i really appreciate it. just downloaded the flashable cwm however it's still the same bro. lemme tell you something though. i rooted the devices before using framaroot and everything is ok but i had to do a factory reset through the settings app in A706. i still see the superuser app in the system apps and i cant uninstall it. when i open the superuser app in the drawer it's giving me an error that the su binary is not installed and su cant install it.

ok, please tell me if you have CWM installed on your device? I believe it is not installed. if this is the case, then you need to flash CWM and then try installing the zip again.
if it is installed then, i believe the super su from previous rooting maybe causing the problem. check on Playstore for a method to unroot your device. or google it. then you need to root again. hope this solves your problem.

thanks
Hi bro thanks for the reply i attached a screenshot of my root validation. I used an app to identify that. And by the way my recovery is installed. I the super su app is killing it

New page for our devices :good:
I had rooted my Lenovo A706 before You made this page You are faster than me , bro :laugh::laugh:
Hope our A706 will have more ROM, Init , Kernel that make it better

Some picture of mine, they are old ones..I am cooking some new thing on A706...:laugh: hope you like

We need a clearing house of concise information for the A2107A to address FAQ
(Much of this information can be useful to other MTK devices)
-----------------------------------------------------------------------------------------------------------
Please reply to this thread with any FAQ items you wish to see here.
-----------------------------------------------------------------------------------------------------------
Q: Why are you doing this? Creating a FAQ?
A: Because my brain hurts and I'm a slow reader. There are a few A2107A threads, but the main one has well over 1800 posts. We need to learn, not just follow recipes. We need to build our understanding with unhindered flow of information.
Q: What are the main threads for A2107A users?
A:
Lenovo IdeaTab a2107
Lenovo IdeaTab A2107A-F roms
Lenovo IdeaTab A2107A-F
A2107A-H Firmware update, Custom Rom and CWM Recovery (calling feature - unlocked)
[ROM] SE for Lenovo A2107A-F and A2107A-H
Q: Should I buy an A2107A?
A: At this point (Sept 2013), new ones are not a good value, but used/refurbs can be a good value. Lenovo themselves have better values: A1000 and A3000. I would like to know and post if these have 3G GSM SIMs? UPDATE: If you really want a 3G SIM tablet, this may be still king. The A1000 has no SIM. The A3000 has an LTE SIM.
Q: Are there custom ROMs? (NEW)
A: Depends on what "custom" means to you. I've stripped some stock ones down: http://forum.xda-developers.com/showthread.php?p=46201425 and makbro collected some... chinese, foxtrot, pemergency: http://forum.xda-developers.com/showpost.php?p=37409096&postcount=800 which I also mirrored here: https://drive.google.com/?authuser=0#folders/0B8PcIZoLeGNuWS1JUnA2UXdPYUE
Q: What is different about MTK devices from my phone (Motorola, Samsung, etc)?
A: MediaTek SoCs are cheap. They seem to be unique in that they allow for some low level fiddling where others don't. The low level fiddling is done with MediaTek software called SP Flash Tool (Smart Phone Flash Tool).
Q: It seems, this little beast is a lot more complicated to mess with, than other devices?
A: MediaTek devices are a pain in some respects... but once you use and understand MediaTek's SP Flash Tool -- you actually bypass a lot of complexity. You are able to write blocks anywhere in flash. And also, read blocks anywhere from flash. So you are in full control.
Q: Can I get an update.zip and put it on my sdcard?
A: Some folks (myself included) have grabbed OTAs, but they are not full flashes, they are just updates. Lenovo has not released official update.zip files for these devices. You may find something, I'd like to know. (You have other paths with CWM Recovery and also SP Flash Tools)
Q: What is the difference between a -H and a -F model?
A: There are 3 distinct hardware profiles: -H with 1 GSM SIM slot, -H with 2 GSM SIM, and -F with no SIM. Check the A2107A wiki here: http://forum.xda-developers.com/wiki/Lenovo_IdeaTab_A2107A
Q: Are there different Official ROMs?
A: Yes, there are at least different -H ROMs for US, Europe, and China. The Chinese ROMs enable a Phone App on the -H. To my knowledge there is just one -F ROM.
Q: What are the current stock ROMs?
A: If you have a US -H and OTA it as of Sept 2013 -- you will get Android 4.0.4 (ATT build A2107A_A404_000_033_121011_ATT)
A: If you have a US -F and OTA it as of Sept 2013 -- you will get Android 4.0.3 (build A2107A-F_S486_130221).
Q: Can I root after an OTA?
A: Yep, root4.03.zip etc should work fine. [Assuming there will never be 4.1 OTAs]
Q: Can I flash -H to a -F?
A: First, ask why do you want to do this? The phone software on a Tablet without phone (SIM) hardware won't get you anywhere. Yes, you can flash -H onto -F, and you will likely not like the results. It is jerky and sluggish and has some errors. For example audio breaks up horribly and swiping between homescreens is jittery. You'll want to go back to a -F ROM, and it's hard.
Q: Does the -F model have FM Radio hardware?
A: Yes! Tapping into it though is not easy. It's not as simple as grabbing the FM_Radio_1.0.apk from the -H ROM and installing it. Apparently the kernel driver on -F is missing, because the app wants to close and can't find any signals. On the SAME -F device, using the -H ROM, I'm able to hear FM Radio.
Q: Who do we owe thanks to?
A: Lots of folks, but makbro, FoxtrotKZ, and pemergency have to be at the top of the list.
Q: Are there custom ROMs for the -H?
A: Yes, check out makbro's post http://forum.xda-developers.com/showpost.php?p=37409096&postcount=800
Q: Are there recovery ROMs for the -H?
A: Yes, check makbro's post above and ClearSky or ANTIKIRPICH are within makbros posted SP_Flash_Tool_FULL_A2107.rar here:
https://docs.google.com/file/d/0By3a11Z9icECSXVLWUl4djc3WTg/edit?pli=1
(this is a very good rar/zip/tarball to grab, almost all you need... props go to FoxtrotKZ)
Q: Are there custom ROMs for the -F?
A: ShilohDaniel has stripped the stock ROM and I believe added some things -- calling it "A2107A-F Bare Bones ROM." thread: http://forum.xda-developers.com/showthread.php?t=2213225
Q: Are there recovery ROMs for the -F?
A: Not really. Once I broke my -F I pushed ClearSky (-H) on it. It was semi-operational, but then getting the right partitioning back to -F was horrible. In this respect, getting CWM on and going with Bare Bones ROM wouldn't get you fixed. I hope to change that.
Q: Will Lenovo release more OTAs? JB?
A: No, they already have a new line-up. They are "done" with these devices. The only thing that would change that is if a partner like AT&T needs a security fix.
Q: Is there a JellyBean ROM for either the A2107A-F or the A2107A-H?
A: No, are you volunteering?
Q: Does Lenovo respond to questions on their forums?
A: Probably not the questions that you would ask. Their answers are more "Well have you tried turning it off and then on again?" When I asked if there were model variants they had no idea. They didn't know if different features were enabled (with different ROMs) in different countries. Their online support chat was able to find a few product PDFs that show several long model numbers. (those PDFs are on the wiki)
Q: Can I use all these untrusted tools inside a VMware virtual machine instead of my daily rig?
A: Yes. I encourage it. Also, if you are using VMware snapshots or VirtualBox snapshots you can roll back and try different drivers. It seems trying to replace ADB USB drivers that don't work with MTDRT is very hard. Rolling back is much easier than trying to expunge the already installed driver so you can try another.
Q: What is MTK Droid Tools?
A: A Windows app that will convert a "firmware.info" to a scatter.txt file.
A: This tool is also able to root some devices and do a backup. I imagine if it gets that far it can restore too.
Q: What is MTK Rom Studio?
A: A Windows app that will convert a "firmware.info" to a scatter.txt file too I think. (I haven't used it)
Q: Why would I want a *_scatter.txt file?
A: It contains the partition information for your device. This is something you need to feed SP Flash Tool so it can flash the bits in the right places. You can make one from a working device by dumping a "firmware.info" file with a tool like the gscript backup method or presumably MTK Droid Tools will build you one right off, I'm sure doing the same thing to get the data which is dumped to firmware.info.
Q: Can I brick my -F or -H?
A: Probably not. There is a Meta Mode that you can get into even if your PRELOADER is broken/overwritten. I verified this today by writing zeroes to the first 16K of flash, broke my -F, then wrote over a known good firmware. makbro believes it's unbrickable and also yuweng has good info: http://forum.xda-developers.com/showpost.php?p=34914486&postcount=3
Q: How do I get into Meta Mode?
A1: While plugged into PC... Hold down Reset, hold VolUp, release Reset, release VolUp
A2: While off... hold VolUp, plug into PC, release VolUp
A3: While off... hold Reset, plug into PC, hold VolUp, release Reset, release VolUp
Q: Can someone help me unbrick my tablet?
A: I haven't seen a bricked A2107A-* that I could not fix. Please post to the original Lenovo IdeaTab a2107 thread.
Q: How do I use SP Flash Tool?
A: I'd like to write a FAQ on it too since there are many pitfalls, but I fear I don't have enough time to do everything. For now, here is a tutorial: http://forum.xda-developers.com/showthread.php?t=1982587
Q: What should I know about SP Flash Tool?
A: SP Flash Tool allows you to read or write any chunk of nvram/flash. It's normal operation though is to load a *scatter.txt file which describes different image chunks and allows you to "download" (write) them to MTK devices. You can think of the NVRAM as a disk (block device) and this scatter file describing the sizes of PARTITIONS. I think in one error I ran across even says your PMT (partition table?) doesn't match. So the download will write blocks of your NVRAM from image files on your WIndows computer.
Q: When I try to Download (write) a scatter and set of image files to my tablet with SP Flash Tool, I get a PMT does not match. What is causing this?
A: Well, for some reason you have to "Format". Not only do the Format, but you must select "Whole Flash". (assuming this next part) Then it write the PMT to your tablet to match the scatter file you have loaded. At this point you can Download (write) successfully. You will want to have a good backup of your NVRAM block or /data/nvram directory first!
Q: What is a PMT?
A: A partition table that holds the addresses to all the other partitions. I believe the PMT block is created by SP Flash Tool dynamically from scatter file. It's comparing the scatter file with what is sitting at the PMT address on the flash. If these two mismatch, you get the error you mentioned. If you want to force a new PMT that matches your scatter file's layout, you have to do a "Format" in SP Flash Tool. This will get you back to a PMT on flash that matches your scatter file, then SP Flash Tool will be happy and allow you to use Download (write to flash). SPFT is very picky about the scatter file matching the PMT on flash, even the __NODL_ in the scatter has to match the PMT.
Q: How do I get into Factory Mode?
A: Turn Off completely. (no power from USB, you might even hit the reset button)
A: Press and hold Power On and VolUp for 12 sec
A: Observe a menu similar to recovery but with tests etc
Q: How do I get into Recovery Mode?
A: Turn Off completely. (no power from USB, you might even hit the reset button)
A: Press and hold Power On for 4 sec, release, then hold VolUp and VolDown at the same time for up to 10 sec
A: Observe the stock Recovery or CWM if you've replaced the stock
Q: Why is SP Flash Tool giving me errors?
A: SP Flash Tool is not quality software, IMHO. I've had it give me BROM ERROR:S_DL_GET_DRAM_SETTING_FAIL(5054))... over and over, then I exited out and got back into the program and flashing worked fine. Also, make sure you have PRELOADER etc files associated with the blocks even though you don't have them selected to Download/write to flash. For some reason, SPFT checks these things even if they are irrelevant.
Q: I don't have a scatter file, or I have an incorrect scatter file... how do I create one if my device won't boot?
A: Interestingly enough, SPFT reads the PMT during a Download/write. It puts all the values of the PMT in it's log file. You can go look at the log file and fix your scatter file. This is cheating... knowing exactly what your scatter file needs to look like to match your device.
Q: I renamed the scatter file from MT6575_Android_scatter_emmc.txt to my_failed_attempt_scatter.txt is that ok?
A: Obviously you didn't know to ask this question and it's just contrived.... but yes you just screwed up, the file name of the scatter matters. I hate this, I lost like 2 weeks to this. Don't rename it. I've found some names that work, but just don't go there, leave the name and organize things with directories instead of file names.
(Some dumb Questions I had early on... that didn't seem to be answered clearly)
Q: How do a SBF or ODIN a A2107A
A: MediaTek's method is through software called SP Flash Tool. This is similar in function to Motorola SBF or Samsung ODIN.
Q: How do I get into Fastboot?
A: I don't think you do on MTK devices.
Q: How do I boot into the Bootloader?
A: Not sure if they have a bootloader menu. I think this is irrelevant. After an OTA, I was never able to. But with all the methods of gaining root and flashing, I guess I don't see why you need it.
Q: Does this device have a locked bootloader? Can I unlock it?
A: I'm not sure. If it does, you could probably overwrite the bootloader easy enough. Can the stock bootloader boot a homebrewed kernel? So far, I have seen no one produce a homebrew kernel for either the -F or -H. Hacks come from the stock kernels or the Lenovo A750 phone.
Q: Can the A2107A run Cyanogenmod (CM9, CM10)?
A: No. Cyanogenmod may run on MTK (MediaTek) chips soon, but even after that it will be a bunch of work.

Backup / root / recovery
Lenovo IdeaTab A2107A -F -H Tablet FAQ
CONTINUED DETAILS!
(but applicable for MT65xx devices)
Backup -- Post 3
Root -- Post 4
Recovery -- Post 5

Topic #1 - Backup
Before you start rooting, I highly recommend getting a full dump of your ROM. And why not? MediaTek makes it easy! At the very least, get a dump of the NVRAM partition. And if you really want to be risky, you'll just get a copy of /data/nvram.
Why Backup?
* First, so you can get back to a factory state.
* This is really good if you return your device or have it serviced.
* It's also good if you are going to sell it.
* Last, if you break it (semi-brick it) you can go back to this known working state.
Methods:
* SP Flash Tool - covered here
* rua1's MKDRT MediaTek Droid Root Tool - covered elsewhere
* Mobile Uncle backup of MEI - may cover here soon
SP Flash Tool BACKUP
If you are big on making images of hard drives, your going to like this tool. But, SP Flash Tool has some bugs and is designed a bit weird.
There are 4 main features to be concerned about: "Format", "Download" (write partition blocks), "Read back" memory, "Write memory".
To backup, you really want to be using the Read memory tab of the interface. But first, you need to make the tool happy.

Perfect Total Backup of your Firmware
Here is a cookbook for doing a total backup of your MTK device with MediaTek's SP Flash Tool. No rooting, you might even do this before you ever boot! I have basically done this with both of my devices before I fiddled too much. I recommend doing it before you do anything really.
1. Install VCOM Drivers. I'd use this: https://docs.google.com/file/d/0B8PcIZoLeGNuUTFIT1J2eXNFd28
2. Install SP Flash Tool. I'd use this: https://docs.google.com/file/d/0B8PcIZoLeGNuVDluTXk4QXdQaUU
3. Grab a -H scatter file with accompanying block images, just to make SP Flash happy. I'd use this: https://docs.google.com/file/d/0B8PcIZoLeGNuM3lxakdIU2hvWTA
4. Run SP Flash Tool, Open Scatter File
5. Don't play with anything, go into the "Read back" tab (This will read your flash to a file on your PC)
6. Click on any items in the list, then click the "Remove" button
7. Now click the "Add" button
8. Double click on the "N/A" under Read Flag
9. Type a file name to write to, like "WHOLE_ROM"
10. Now it will popup a window "Readback block start address"
11. Leave "Hex" selected, Start Address" 0x0000, Length: 0x323E4000, Click OK
12. Click the "Read back" button
13. SPFT now waits for you to connect your device and put it in Meta Mode
14. Without plugging your tablet in, tap the Reset Button on the back under the camera
15. Hold VolUp, plug in USB, Release VolUp (putting it in Meta Mode) <--- Important
16. You will see the progress bar moving. Total backup takes forever, because in this mode SPFT seems to not do USB HIGHSPEED
That's IT! Go to bed, check on it in the morning.
If you ever restore, just go into Recovery and Wipe Data and Cache. (as these are large and we didn't back them up above)
Note: "Length" in Step 11 is extra long. If you have a 4 or 8GB model it actually backs up part of your cache partition block too. But this is the right length for the 16GB model and it doesn't hurt to backup too much.
(If anyone would like to share there's with me, that would be great. I only want stock dumps though, for comparison purposes.)

Topic #2 - Root
Note: MediaTek is very different as you have low level access to their Flash. Ask
yourself if you really need root. MediaTek's tool SP Flash Tool is very powerful. You can dump your stock rom, replace your recovery image, or blow on another SPFT ROM. So, unless you want your STOCK ROM ROOTED, you can probably skip rooting your stock ROM in the first place.
Why Root?
You have very little ability to do backups or change your device without rooting it. You can use vendor tools to do backup/restore of your user data, whatever they determine is your user data. You can use Android "Factory Reset" which just wipes the data and cache partitions. If you want to do more, you need to root.
More access like:
* Complete backups of ROM (although a bit sketchy to backup a running system)
* Install busybox
* Install apps requiring root, Root Explorer and WiFi sharing
* Install drivers, like OpenVPN, alternative wireless drivers, OTG, FM Radio?
* Install sshd server etc
* Do custom theming?
* Performance tweaks
* Remove APKs from /system/apps (scary)
Different Methods - I think all rely on the same mechanism
1. 4.03root.zip (requires working ADB and Windows)
2. setools/seroot (syserr's port of 4.03root.zip to linux shell, instead of .bat)
3. SRS Root (requires working ADB and Windows)
4. rua1's MKDRT MediaTek Droid Root Tool (requires working ADB and Windows)

Topic #3 - CWM (Clock Work Mod) Recovery
Why?
CWM Recovery is awesome. It allows you to install custom ROMs as long as they are "CWM" compatible. CWM Recovery is a lot like a typical stock Recovery but better. For new people, a Recovery is basically a minimal Android system that allows you to do maintenance on the device and reload etc the main operating system. On MTK devices the Recovery image sits on the RECOVERY partition. You usually press certain buttons early in the boot process to "boot into Recovery."
Different Methods
* SP Flash Tool
* MobileUncle (requires root)
* rua1's MKDRT MediaTek Droid Root Tool (requires root)
* dd / flash_image (requires root)
SP Flash Tool Method
Disconnect Tablet from PC
Run SP Flash Tool (exe)
Select Scatter File
Uncheck all block partition checkboxes except for Recovery.
Click on the Recovery text/tag and then find the CWM Recovery image you desire.
Select Download, SPFT waits for device
Hit reset on Tablet
Press VolUp, connect USB, Release VolUp (to get to Meta Mode)
SPFT ALWAYS finds device this way.
You should see progress bars moving, and it complete

I get paid with "Thanks." So, thanks! :good:
I've often wondered if forums are the right structure to capture this information. When I finally decided to dive in deep, I had to make notes of which posts had good information - it took 3 days of solid reading to make sense of it all. There are plenty of posts that have incorrect information or irrelevant information.
Good luck.

I need some help!

whilst this is not really friendly I'll try answer.
when hex number i advice you to use an hex calculator because this is 16 base not 10base that's why you would be better using a hex calculator.
this all about readback the memory for backup purpose so according to my file:
I do not understand. How Lenght you have used

take my file as example and i would bump the partition cache, i would do:
readback: start adress:0x0000000050980000
: size : 0x0000000007e00000 = 126 Mb
: lenght: 0x0000000050980000+0x0000000007e00000 = 0x0000000058780000 (end adress)
this should result by a file.img of 126Mb with by spft on readback memory starting adress at 0x0000000050980000 and ending at 0x0000000058780000.
you can see that this overlapted the next partition 0x0000000058780000 (userdata) so i bet that spft does this to not overlapted start adress of next partition:
0x0000000050980000+0x0000000007e00000-0x00000000000001=0x000000005877ffff
i hope this explanation is readable and will answer your question.

What Scatter file ?

My bewilderment came from that and MTKDroid do the same, add preloader - in my case CACHE : 0x3c3c00000 (from firmware.info) + 0x00600000(preloader) = 0x3C9C0000(that we used from READ BACK with SPFT).
I understand that the scatter file created with MTKDroid Tool is not good ???

I believe "MTK Droid Root & Tools" does give you a good scatter file, but I've actually never used it.
Background: During the time I used it, I had major problems with ADB drivers on Windows. I ended up soft-bricking my device by playing with the "Test" tab in SP Flash Tools. So when I came back to working on things again, with a new device to donate the ROM, I wanted to be absolutely sure I knew what I was doing. First thing was "Read back" the ENTIRE ROM of the new device. This is an insurance policy. I had made backups with the GScript mtk*backup.sh scripts that run ON the unit, so I never went back to MTK DRT.​Something I think everyone that wants to do HEX math should to is start playing with the python interpreter... it is AWESOME. :good:

Alex1948, if you are wondering why the length of my full/entire/whole dumps seems arbitrary... my answer is in some cases I was guessing at large enough numbers. My device (A2107A-*) has at least 5 different partitioning schemes from the factory. I want extra length, I didn't want to tell someone to read too short.
Why I am reading to the start address of CACHE is because that is the end of ANDROID. This is just looking at the physical real addresses in the scatter file. How those addresses are calculated from firmware.info/dumchar_info is a different story. I think you are aware of adding the 0x600000. This is only added to the lines in the file that are not preloader or dsp_bl:
Code:

So my code here:
Code:

Is only adding the offset to the partitions that don't have that "misc" in their block device name.
I'm explaining a lot. I'm hoping somewhere in this you have the answer you are looking for.

Thank you very much.I understand something.and conversely :ANDROID 0x123e4000+0x20100000(lenght) = CACHE 0x324e4000
I wrote on the other thread

A3000 hardware
Just a note, in Europe and likely in Asian the A3000 SIM version is dual SIM, organised much the same as the A2107A. One SIM is expected to be used for data (HSDP+, this is the European high speed 3G, up to 42mbs, I get 18mbs off my local tower) and one for SMS and Voice. You can run SMS on the Data SIM if you are provisioned, I do. The European firmware does not support GSM voice (again) but Asian and Middle Eastern does. Why Lenovo does not include voice support in the European firmware is a mystery.
Many thanks for the A2107A FAQ, I'm selling one now, replaced by a A3000.

Not create worry... but I have a very cheap ($75 sale) Lenovo A1000 coming. This has JB, FM Radio, and dual-core. This is going to work out better for a in-dash car system.

Partitioning 16 GB A2107A-H
Does anyone please have an EBR1 and EBR2 (or other means) by which I can repartition my internal SD flash so that the system and other partitions are larger?
I have read about an apk to do this for the 4 GB model, and also the limitation to one of the partitions (32-bit addressing?) to 2 GB, but have not found anything available for the 16 GB model.
Could anyone please advise and/or upload the necessary files?
Also, does anyone have a view on the "best" ROM? It seems all have compromises in some way, including the stock ROM. Pemergency looks good unless someone tells me otherwise.

This device has a Mediatek MT8127 processor unlike it's predecessor the RCT6103W46 which has a RK3188T processor.
I fully updated this device, out of the box, and was able to root, flash TWRP, and make a backup using this method.
These instructions and recoveries are for this device ONLY. I am NOT responsible if you flash the wrong recovery to your device.
However, if you do, and have YOUR OWN pulled copy of recovery, you can use Rashr to flash your copy back.
I figured that out by trial and error while trying different TWRP.
On your device, go to About Tablet >> Tap on Build Number until you enable Developer options.
Now go to Developer options and enable USB debugging.
If you are on Windows 8, plug in your device and let Windows install the drivers itself.
Install SuperSU from the Google Play Store but don't update it yet if prompted.
Download, install, and follow directions on Kingo App to root the device.
You can check to see if Kingo properly rooted the device using Root Checker Basic.
Update SuperSU. You will no longer be able to uninstall it via Apps.
Download Rashr to your device.
Download TWRP from the bottom of this post. (Credits to PatF for originally posting TWRP.)
Unzip then copy TWRP.img to your device and flash it with Rashr on the device.
You can reboot to Recovery from Rashr when prompted to verify that TWRP has successfully flashed to your device.
The original Stock Recovery is at the bottom of this post if you want to go back to stock.
ROOTING your RCA RCT8203W46 device has been known to soft brick if you accept a FIRMWARE UPDATE.
Return to stock and unroot before accepting a Firmware update!

Take the first and second Hexadecimal numbers and turn them into Decimal numbers.
Then divide them by 4096 to get the Count and Skip.
Code:
Hexadecimal Value Decimal Value
0x0000000000600000 -----> 6291456 / 4096 = 1536 ---> count
0x00000000007e0000 -----> 8257536 / 4096 = 2016 ---> skip
Now use dd to extract the bootimg partition.
Code:
dd if=/dev/block/mmcblk0 of=/sdcard/recovery.img bs=4096 count=1536 skip=3552
You should now have a boot.img file. Proceed to next section to unpack and repack the boot.img so that you can build a Custom Rom. If you do not do the next step, breakfast won't be able to read the zimage because it is not actually a gzip file.
Legend:
bs=block-size
count=number-of-blocks
skip=input-offset
Section B
This part was done exclusively on Ubuntu.
Use repo and get mtk-tools.
Code:
git clone https://github.com/bgcngm/mtk-tools.git
Now use unpack-MTK.pl and repack-MTK.pl to unpack and repack the boot.img file.
You should no longer get the error gzip: ../boot.img-ramdisk.gz: not in gzip format when building Android.

Good luck!

don't use reset + power + vol minus
use power + volume increase (+)
if all else fails hold both volume buttons at the same time... wait for the dog screen to end and it will give you recovery
it won't let me post a link, so, here goes a try... you need to go to naijarom dot com forwardslash rca-rct6203w46 forward slash <-- stock rom and flash tool with instructions

Backup/Root/Recovery
DISCLAIMER:
Rooting your phone and using custom Recoveries and ROM's 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 knowledge about the phone and phone utilities also.
Make sure that whatever you do, you are doing it at your own responsibility.
How to backup of your stock ROM, install CWM and Root your device.

Unbrick your Tab!
To unbrick your device all you simply have to do is go back to the CWM and restore your backup that you created earlier. If you don't have one, here is a copy of a working backup ---> Google Drive. Credits to @andrei_kr, say thanks!

How to fix touch!
If you unbricked your tablet and your touch isn't working, there is no need to worry. @andrei_kr has provided a guide on how to fix that touchscreen. Credits to him.
NOTE: If your touch is working then do not try this, it will mess up your touch!!
You probably got this touchscreen issue by flashing a different kernel with incorrect drivers.
Now your configuration is likely to differ from the native. You can view the konifig in command prompt or in the terminal :
Code:
cat /proc/gt9xx_config
(only mtk) or using the gtp_tools apk (it is in the attached file below).
It starts with the byte sequence: 0x41 0x1C 0x02 0xC0 0x03
0x41 - 65 version
0x1C 0x02 - 540 horizontal resolution
0xC0 0x03 - 960 vertical resolution
Touch must somehow work to press the button, if there is support otg, then it's easier, you can connect a mouse.
1. Install the gtp_tools_v2.6_20140126_special.apk
2. Go to the option Firmware update. Click refresh, see IC Version: 913_1020 then touch GT913 firmware and 1020.
3. Go to the option Config Settings, press read, the data were considered. Under Normal Config we have:
65 version
540 horizontal resolution
960 vertical resolution
4. Click browse, select click browse to the native config.
5. Native configuration take from your device, in the same paragraph, press the save (saves the backup config file). Native configuration for Fly IQ446 in the attached file. Press send.
6. If nothing has changed, look at the version you have and native config. Then change the version of the file in the native config in your hex.
Example: 0x41 = 65 home, a stranger 0x49 = 73 => replace the 0x41 to 0x49.

Thanks for report.

First want to say much thanks for this thread, it was getting frustrating trying to find a solution.
I have encountered a slight issue trying to unstuck 2 of these devices.
neither have been rooted and are stock devices.
i cant seem to get cwm to locate the backup that you supplied.
do i need to copy it to the cwm backup folder on my sd card?

Yes you do. Copy it to your sd card. Btw if your device is stock why do you want to restore this one?

NuVision TM101A510L
Will this method work with the NuVison TM101A510L. It seems like a lot of work to do if I'm not sure about this model. Also I have a problem with this model overheating and crashing when I play Pixel Gun 3d and it's pissing me off. I just fired off a curse filled missive to NuVision support. They don't even list this model on their registration page and it seems they have no faith in this model. I will never buy this brand again, in fact I would recommend against it to my customers. I've used Azpen tablets with no problem rooting or playing Pixel Gun 3d. I took a chance and I'm so damned sorry I did.
;angry

Thank you so much for this thread!!! I have been looking for a recovery for a few months now and cant believe I didn't find this until now...

ok so a minor problem... I cant seem to flash the recovery... Not sure if ive placed the recovery file on my sd card properly or not cause i locate a few backup files none of which have any effect. I gave up in frustration untill now. ( Currrently working on a few androids one rooting one imea changing so figured id take a crack at these devices again. THe layer of dust on these things are getting a bit thick.)

I think the models numbers are specific so I can't say for certain that this will work with your tab. Try the fastboot/rooting procedure first and then maybe you can just restore the system partition only not corrupting the boot/kernel.

You are using the fastboot method correct? If the recovery script says finished as in no errors show on the screen then it could be the device itself. What do you see?

ill let you know just as soon as i can get back to working on those devices... im prety sure if memory serves correctly, that I was getting some errors regarding unable to mound sd or ext sd. I could be wrong but thats what comes to mind.
Im up to my neck in jobs on other devices. (rooting galaxy S5, changing imei on another S5, IMEI change on a LG Stylo 2 plus, Galaxy Tab 2 system issues need to diagnose, and several screen and lcd replacments)

STUCK
ok so i have a little time to work on these....
When i run the launch.bat and get to fastboot, it goes through the instalation and everything checks ok till the very end where it says failed cause too many links.
included the screenshot so you can see.
At this point im unsure if i just need to try flashing the supersu zip like it instructs but having tried befor it had no luck.
can I not just flash twrp on this thing then su like with most root methods?

after ive flashed super su, when i go to restor the working backup i see a list of backups... including yours but when i select it i always get :
checking md5 sums...
md5 mismatch!
what now?
(i tried just flashing the boot but even that comes back with same error)
I know on other devices the recovery is an img file any the one you provide is a rar... i extracted to my desktop and was gonna try flashing with abd/fastboot but since its not an img file, im thinking it wont work...
any thoughts?
Im still unsure how to flash the recovery that u supply in the section for fixing bootloop....

The too many links error is common for this device. Touch doesn't work with TWRP on this device so CWM is out only go. You can root and using cwm like any other root method.
