[Completed] Need to Install Custom Recovery through ADB - XDA Assist

If a mod could be so kind as to move this to the correct area if this location is incorrect I appreciate it.
Recently I've been given a pretty crappy tablet, but nevertheless I want to get it in working conditon. I love the challenge and I love the opportunity of being able to learn something new.
The specs of this Tablet device are as follows: http://www.sears.com/ideausa-idea7-7inch-tablet-w-dual-core/p-SPM8151247717
Maker: IDEA USA
Model: CT720
SDK: MID-A20-Android4.2-v2.0
Android system recovery <3e>
The owner of this tablet says they went to turn it on one day and it said no operating system found. other than that I have no information other than what is listed previously.
So when turned on I get the green android logo looking like its an android guy putting his arms up. it stays stuck there. I've never once gotten a screen saying no operating system found.
when I turn it on with power + volume up I get recovery mode
power +volume down as well as power + volume up + volume down do not do anything except boot the green guy back up.
I figure through recovery I can maybe get cyanogen onto this device and figure things out along the way somehow.
I boot into recovery mode and of course the volume buttons do nothing even though the screen states to use the volume buttons to navigate. I use adb to reboot to bootloader, where it goes to the green guy again. I check the device status and it says it's status is device.
I use adb to reboot to recovery and it's back at the same screen where the volume keys do nothing. I find some adb commands to push button presses across, no luck as it says
'/system/bin/sh' failed: No such file or directory (2) -
So far I'm thinking my only chance in hell is gonna be if I can force push a different recovery over this one which I'll actually be able to use, followed by trial and error with different roms.
any recovery images I get are ISO files, and I can only adb push .apk files. I'm definitely missing something here as I don't have too much knowledge at this level of android devices.
any help I can get I greatly appreciate it.
---------------------
edit .
when the green guy comes up, im able to adb shell in. I don't know if this helps any, I'm going to continue researching a bit and see if there's anything I can figure out

now that I'm able to shell in I'm able to tell that there is still an operating system. and all files seem to be fine and intact. not sure what's causing this

So I had figured I would make an attempt at messaging the maker IDEA USA and seeing if they could provide me with with a rom.
luckily I received an email providing me with an official .zip which I have hosted here: https://mega.nz/#!mwcmGaiB
The rest of the email stated as follows;
"The Software needed is called PhoenixSuit V1.10 (i used 1.0.6)
You will need a PC with Windows 7 or above
Micro USB to USB Cable (Supplied with your device)
Open the software
Click on the Anchor with Firmware underneath it (See Photo attached)
Click on the Blue Image button, Navigate to where you have the Firmware Image on your device.
With the tablet off Connect the device to the PC.
Press and hold the Volume up (+) key and hold it
Press the power but approx 6 times quickly and you should see the device start to load the firmware.
It should show device connected in the lower left corner of the software. "
I ended up just having to turn it on normally and it auto detected after following the previous instructions. Flashed the firmware and worked like new. Hope this helps anyone else out there with any troubles!

I still would like to put a recovery on to this device, twrp and cyanogen cannot find a compatible recovery. Any direction on where I could go from here?

Hello,
If your device has no custom recoveries available then you can try getting someone to build one for you or you can go to XDA University and find instructions for porting a recovery from another device or you can find how to build a recovery from source, there are many links and some menus that have other links at XDA University, check them all until you find what you are looking for.

Consider creating a thread with detailed instructions for how you corrected your issue, you can put it in the Android Development and Hacking forum. It would help a lot of others with your device if they have the same issue. The thread doesn't have to be fancy, just list the steps and links to the files needed(including firmware link, flash tool link and anything else that is required). It shouldn't take a lot of trouble to put the thread together. The community would appreciate it.

[How-To] Unlock Bootloader and Root

To start off everyone should know that messing with your phone can brick it!! You should not mess with your phone if you are unsure of what you are doing. You will get this (or a similar) warning while following the unlock instructions from Motorola as well. Following these instructions also voids your warranty!
I only use Motorola's official firmware for the moment and these instructions were originally performed on the ASA14 firmware. They should be useful for previous versions of the firmware but I will not be testing those. These instructions may not work for releases after ASA14.
While following this guide you need to be on a Windows PC with the administrator account or an account with administrative privileges. If you do not have these privileges you will likely run into issues. All instructions are written for a PC running Windows 7 as that is the only PC I have access to. If anyone has any instructions using a different version of Windows I will gladly add them in.
Windows commands:
dir - Lists all directories (folders) and files of the directory you are currently in.
cd {directory name} - Moves into the named directory. The directory names are case-sensitive.
cd.. - Moves to the directory before the one you are currently in. For instance if you are in C:\Users\Public and perform cd.. you will move to C:\Users
{Unlocking the Bootloader}​
I'm writing this pretty late and formatting takes forever so I'll update this section later with my own set of instructions. For now use this guide which I plan on using for inspiration since I can't really repeat the unlock process.
Below is my work in progress. This is incomplete and will be unhidden when it is completed.
Updated Unlock
1. Download the Android SDK
2. Unzip the file. If you don't have a program to unzip the file 7-zip is great.
3. Move the unzipped folder to a location that is easy to locate. For me I put this in "Documents".
4. Rename the folder to something shorter, that way it's easier to type in later. "ADT" is easy to use and remember.
5. Download the drivers for the phone.
6. Open "MotorolaDeviceManager_2.3.9.exe" and install the drivers.
7. Go here
8. Click "PROCEED ANYWAY"
9. Register an account with Motorola.
10. Go to Start > All Programs > Accessories
11. Open “Command Prompt”
12. Use the cd commands to navigate to your “platform-tools” folder.
13. Turn off your phone (power button + volume down if you can't select any options to turn off the phone)
14. Turn it back on using the power button + volume up + volume down combination
15. Select “Fastboot” (volume down cycles through, volume up selects the option)
16. Connect your phone to your PC.
17. Type "fastboot oem get_unlock_data" in Command Prompt.
{Installing a New Recovery}​
For the recovery we’re going to install the Photon Q Open Recovery. Every recovery has its advantages and disadvantages. This one is familiar to me and so I chose it for this guide.
1. Download the recovery image
2. Place the image in the Android SDK “platform-tools” folder which is in the "sdk" folder
3. Turn off your phone (power button + volume down if you can't select any options to turn off the phone)
4. Turn it back on using the power button + volume up + volume down combination
5. Select “Fastboot” (volume down cycles through, volume up selects the option)
6. Connect your phone to your PC
7. Go to Start > All Programs > Accessories
8. Right-click “Command Prompt”
9. Click “Run as administrator”
10. Use the cd commands to navigate to your “platform-tools” folder (Unfortunately I cannot tell you where this is as each computer will have it placed differently)
11. Type in “fasboot flash recovery open_recovery_206_05_06_2013.img”
{Getting Root}​
1. Download the zip file for rooting
2. Place the file in the root (ie. not within a folder) of your phone’s SD card
3. Turn your phone off
4. Turn it back on using the power button + volume up + volume down combination
5. Select “Recovery” (volume down cycles through, volume up selects the option)
6. Select “Apply Update” (In recovery the the controls change. Volume up and volume down move in the list, the camera button at the bottom right of the device selects.)
7. Select the file you placed on your SD card from step 2
8. Wait for the update to apply, it should say that it finished successfully
9. Select “Reboot Phone”
Credit for all of this goes to their respective creators. I will name them all by name at a later date, but the credit can also be found following the linked material. Hopefully that doesn't bother the creators, writers, or hosts.

Please don't re-post this how-to without crediting. I've had it happen before and it was a huge disincentive for updating and making new guides.
section "{Installing a New Bootloader}" and "1. Download the bootloader image" below it are actually reffering to recovery (probably the best one out there). Not a bootloader.
Bootloader boots the system. Depending on keys pressed during boot (if any, or if instructed by commands) it can boot to bootloader menu, recovery, system (android)...
Ah, thanks. I would have known that if I rechecked but I haven't had time to.
Edit:
While I was editing I noticed I referenced it as recovery multiple times and was switching between the two as the guide went on!
unlocking bootloader failed
ok so i got the device id went to the motorola site said it was good got the unlock key did the step and typed it in the command prompt and it says
(bootloader) password incorrect
(bootloader) oem unlock failure
FAILED <remote failure>
sorry if this is a noob question usualy dont post first time last time i rooted a fone was on an evo 4g so never really messed with command prompts and unlock keys to much i repeted the whole process 3 times already and i still get the same message
edit: nvm got it to work hahaha forgot to capslock the letter in the key thanks for the write up man

Yeah, unfortunately there's are a few points where unlocking get's confusing. I had to enter my stuff from the command prompt to Motorola's site like 5 times before I figured out where the copy/paste had spaces. It took me a while to figure out I had pasted an extra space at the end. This was the first phone for Motorola's bootloader unlock plan so I'm hoping they improve on it for their future phones.
The OP is updated with some more color-coding, updated credits (though I didn't try to get everyone just yet), and changed the link to an updated SuperSU. This should work on the Jellybean update though I won't know for sure unless someone confirms it in this thread. I've taken a break from messing with my personal phone for a while so I won't be checking the boards as often but I'll still be checking every few days.

FYI, if you install TWRP it will detect whether you have root or not and offer to install it for you.
Simplifies the guide a bit, and IMHO TWRP is a great recovery - all touch based, no more mashing the volume keys .
Nicely done regardless.
I noticed I was missing a step in the {Getting Root} section. It was an implied step but I added it for clarity.
I also had forgotten to mention that once you get into recovery the buttons used to control things change slightly. You can use the keyboard in addition to the device buttons.
Thanks for the How-to!:good: I was wondering if you would mind if I gave you or added some instructions for Linux users?

Yeah that would be fine. PM me the instructions and I'll test them out on my Linux partition. It'll probably take a few days as I have things coming up.
I've updated the links in the OP to Open Recovery 2.06 (changing the name in the command accordingly) and started writing my own set of bootloader unlock steps. They aren't complete yet but if someone is having troubles understanding the first few steps of the linked article mine should be broken down to be a bit easier to digest.

Open Recovery is on version 2.09 now. Has anyone tried it? I tried it using the posted steps but I got the same result as when I tried cmwrecovery, the phone doesn't boot to it, it boots to an image of the android guy on his back with his belly open and a red exclamation point hovering over him. Any advise? It's a Photon Q using Android version 4.1.2 nand I have successfully unlocked the bootloader.
I never changed versions because most of the updates target Kit-Kat based custom ROMs. Make sure your phone is NOT plugged in when you try to get into recovery. If it doesn't work when not attached to anything re-download the recovery and try installing again.

I have tried to get into recovery both plugged in and not plugged in. I tried downloading and re downloading both CMWrecovery and open recovery 2.09 both.
Are you saying Open Recovery 2.09 is targeted at Kit-Kat custom ROMs and won't work on my phone? Should I try the version in your OP?
It should work in theory regardless of Kit-Kat, but if you've already tried all of that then give the older version a shot. I really post only what I know and have tried in the original post. It's beyond the scope of my thread though so you may have better luck asking in the recovery threads if you can't get any version to work. I'm on my phone for the time being or I would link you to the appropriate threads myself.

See the OpenRecovery thread for a valid link to that recovery... the links are a bit outdated for OR, look near the end of the thread.
I have the link to the Open Recovery thread at the very start of the section about installing recovery. It's there in case links die, someone wants more info on what they're installing, or someone has support questions pertaining to Open Recovery. This thread didn't seem to be very popular compared to one I made for an older phone so I haven't kept it up to date. The phone has been out for some time as well so I likely won't be updating this thread.

BLU Quattro 4.5 (440D) GSM Recovery+Root
Hello... I got my BLU Quattro 4.5 (D440) a while back, didn't fuzz with it much right off. The Stock ROM was sluggish at best thought there was even an issue with the Digitizer/screen. But this thread was extremely helpful. I am now running Shendu ROM 4.1.2 one of the suggested ROM's above. I tried the other 2 first and they were mostly in Chineese and I had an especially hard time getting them switched over to English. Either way onward to the point. I have put together a few helpful tips-tricks for my experience with this phone and its phoenix transition to an awesome handset. Thats right now this is my daily driver and I love it! See below hope its helpful.
BLU Quattro 4.5 (440D) GSM Recovery+Root
These steps for this phone only!! Not responsible for any issues.
1. download ROM's, Recovery, & Driver from XDA (this thread)
http://forum.xda-developers.com/show....php?t=2327417
2. Enable USB Debugging! Go into Apps-Settings-DevOptions - Check box for USB Debug
3. Have original USB cord if handy! I tried with a Samsung OEM cable but no luck getting drivers to stick. Use original is best. (If you have one.)
Plug in USB Cord to PC then Phone and see if windows detects drivers. let it. It wont get the ones u need later, but what it does find is for USB storage. (you can move over your ROM's/Gapps to storage, downloads folder is a good spot).
4. Go to... http://junefabrics.com/android/downloadold.php to get pdanet software. Install it and it will give i the right drivers for ADB support. I used 4.01 to match the android version currently on my phone.
5. Extract the Driver provided from XDA. Put it in a folder with the ADB commands. Or you can get it all here... http://downloadandroidrom.com/file/G...usRootNew.zipn <-- I know this isn't for BLU but, if you extract this to a folder, and also add the drivers extracted to it as well this works! I've done it.
6. Extract the English Recovery to the same folder.
7. Turn off your phone. Hold down Vol up and Power button for about 5-9 seconds. Once you see a green screen let go of both. Screen may flicker then go black but the icons at the bottom will stay lit. You are now in APX mode (nvflash) mode. (as stated above in original post)
8. Check your Win 7 PC device manager. For a Phone device with ADB. If you you may need to update driver with the one that came from XDA, but the PDANet software should make it work.
8. Go to the folder and find Recovery.bat file (may have Chinese in file name. Double click and a command prompt window will pop up with a bunch of unknown characters, wait 5 sec then hit enter. The batch file should take of pushing the necessary recovery through ADB to the phone. It will error if it can't.
9. If completes OK. Push power for 7-9 seconds to power off the phone. Hit power like normal to turn it back on. It will boot up like normal (or it should).
10. USB is still connected this whole time and you can open a command prompt window. Navigate to the folder you placed the Recovery into. Something like user/username/desktop/BLU/recovery..etc)
Type ADB devices....it should show you that is is connected to your device. Then type " adb reboot recovery " and the device should reboot, give it some time.
11. Once in recovery. Best to do a backup of the original ROM & system. that way you can get back into recovery if anything goes wrong and wipe out the problem by restoring and starting again.
After you backup === you can get into recovery without the command being typed in or even being connected to your PC.... By holding Vol up + Power till you see the green screen then let go of power but keep holding Vol up till you see the BLU Products boot screen then let go ===
Clockworkmod Recovery should be on your screen.
you can reboot phone now and get back to original with no changes. Or you can venture into the world of loading ROM's (There in your downloads folder if you saved them in Step 3)
ROM 101
BACKUP-BACKUP-BACKUP 1st thing once in Recovery ...can't stress enough how much of trouble you can keep yourself out of by keeping an original backup.
As I stated before the Shendu ROM + Gapps is running smooth and all features I've been trying are working flawlessly!! Thanks to original post for getting me going. Just thought I'd add my 2 Cents.

[GUIDE] Proscan PLT9650G (RockChip RK3126) Tablet, Root, TWRP, etc

*** Use at your own risk these instructions worked for me on MY tablets that is no guarantee they will work for you ***
This is for the ProScan PLT9650G(K-1G-8G) tablet. It has the RockChip RK3126 chipset. The one I am working with was purchased in Canada at the Atlantic Superstore. I will just briefly outline what I needed and had to do to root and install a TWRP recovery on the tablet. See the attachment for the recovery image. I will explain how to get the programs and general steps to make a full backup of the tablet before ever rooting the device. It is a little difficult, and not necessary, but like any backup can be helpful to have around.
Specifications:
The ProScan tablet has:
- Android Lollipop 5.1.1;
- Quad-core Processor, 1.2Mhz;
- 1 GB of DDR3 Memory;
- 8GB Flash Storage;
- 800x480 Screen Resolution.
Backup Overview:
1) Install USB drivers;
2) Put tablet in bootloader mode;
3) Read the different partitions.
Tools Needed:
1) Rockchip Driver Assistant v4.3;
2) Android Tool v2.3.
Detailed Instructions:
This tablet is a newer version and requires at least version 4.3 of the Rockchip Driver Assistant. The older versions (4.1) won't recognize the USB product id (310D) in bootloader mode.
Download the drivers unrar and run DriverInstall.exe. Select uninstall to clean any old drivers and then select install to install the newer ones. I've done this under Windows 7/8.1/10. Since I've done it so often and so many times with different driver version, I can't remember if the bootloader drivers require you install them with the driver signing turned off or not. The problem becomes that the bootloader drivers (under Windows 8+) will fail the driver signing authentication and won't install. The ADB and MTP drivers are signed and will install correctly, but when you boot the tablet in bootloader mode the device will be unrecognized by Windows. If you end up with this problem follow these instructions and then install the drivers.
After testing on a new machine under Windows 10 the drivers install fine. There is no need to boot with driver signing verification turned off.
To put the tablet in bootloader mode follow thes instructions:
1) Unplug tablet (both power and usb);
2) Turnoff tablet;
3) Press and hold the esc and power buttons at the same time;
4) Hold until the stock recovery menu comes up;
5) Press the esc button to go down to the menu item saying bootloader;
6) Press the power button to execute that menu item.
The screen will go blank. Plug the tablet into the computer and it will be recognized as a device type "Class for rockusb devices" in the Windows Device Manager.
Download the Android Tool from the link provided. The link gives a detailed description of how to backup all the partitions. I have included my parameters.txt file that I created. From the standpoint of undoing the root operation described below I believe only the recovery and system partition needs to be saved. But saving all the partitions never hurts. After you have followed the information in the link and saved the partitions you can move on to rooting the device.
One serious warning I have NOT been able to write anything to the device using the Android Tool. It always give me an error and won't even try. The backups we create can be used from within the tablet to restore it later if needed.
Custom Recovery Overview:
1) Root device;
2) Download the image file on the tablet;
3) Flash the recovery partition with the image file.
Tools Needed:
1) KingRoot;
2) Terminal Application;
Root Device:
The device rooted using KingRoot. Startup the tablet and go through the setup process. Download the apk from the link provided. The version used in testing was 4.6.2. You will need to allow "Unknown sources". The app will eventually give a button just try to root. This will eventually work and the tablet will be rooted.
Extract the img file from within the zip file below onto the internal drive. Make sure you put it in the Download directory. If you are doing this from the tablet it should go there if you move it over using the computer make sure you put it in that directory or change the command below to the proper directory.
Install a terminal emulator. Anyone will do, the one I chose is linked above. Open the emulator and type:
Code:
su
at the prompt. KingRoot should prompt you asking if you want to grant root privilege to the command prompt. Then type the command:
Code:
dd if=/sdcard/Download/TWRP_800x480_Unified.img of=/dev/block/rknand_recovery bs=4096
. That's it if you type:
Code:
reboot recovery
the tablet will reboot and TWRP should start up.
Notes:
If you saved the original system partition you can install it using TWRP and effectively unroot the device but keep the TWRP recovery. With the recovery image you can install it over the TWRP and return the tablet to its stock state. I'm giving these tablets to my kids and I wanted a way to return them to the state I bought them plus after I've personalized them for each of my kids I can make a backup in case they do something that messes them up.
This will also work for the PLT1065G but you need to use different recovery/parameters. The kernel is different (looks like a different touchscreen).
Thanks for this. Got one for $50 at Loblaws today. Will attempt rooting.
Got it for my 6 yr old
Edit: Fixed boot issue

*** Use at your own risk these instructions worked for me on MY tablets that is no guarantee they will work for you ***
This is for the ProScan PLT9650G(K-1G-8G) tablet. It has the RockChip RK3126 chipset. The one I am working with was purchased in Canada at the Atlantic Superstore. I will just briefly outline what I needed and had to do to root and install a TWRP recovery on the tablet. See the attachment for the recovery image. I will explain how to get the programs and general steps to make a full backup of the tablet before ever rooting the device. It is a little difficult, and not necessary, but like any backup can be helpful to have around.
Specifications:
The ProScan tablet has:
- Android Lollipop 5.1.1;
- Quad-core Processor, 1.2Mhz;
- 1 GB of DDR3 Memory;
- 8GB Flash Storage;
- 800x480 Screen Resolution.
Backup Overview:
1) Install USB drivers;
2) Put tablet in bootloader mode;
3) Read the different partitions.
Tools Needed:
1) Rockchip Driver Assistant v4.3;
2) Android Tool v2.3.
Detailed Instructions:
This tablet is a newer version and requires at least version 4.3 of the Rockchip Driver Assistant. The older versions (4.1) won't recognize the USB product id (310D) in bootloader mode.
Download the drivers unrar and run DriverInstall.exe. Select uninstall to clean any old drivers and then select install to install the newer ones. I've done this under Windows 7/8.1/10. Since I've done it so often and so many times with different driver version, I can't remember if the bootloader drivers require you install them with the driver signing turned off or not. The problem becomes that the bootloader drivers (under Windows 8+) will fail the driver signing authentication and won't install. The ADB and MTP drivers are signed and will install correctly, but when you boot the tablet in bootloader mode the device will be unrecognized by Windows. If you end up with this problem follow these instructions and then install the drivers.
After testing on a new machine under Windows 10 the drivers install fine. There is no need to boot with driver signing verification turned off.
To put the tablet in bootloader mode follow thes instructions:
1) Unplug tablet (both power and usb);
2) Turnoff tablet;
3) Press and hold the esc and power buttons at the same time;
4) Hold until the stock recovery menu comes up;
5) Press the esc button to go down to the menu item saying bootloader;
6) Press the power button to execute that menu item.
The screen will go blank. Plug the tablet into the computer and it will be recognized as a device type "Class for rockusb devices" in the Windows Device Manager.
Download the Android Tool from the link provided. The link gives a detailed description of how to backup all the partitions. I have included my parameters.txt file that I created. From the standpoint of undoing the root operation described below I believe only the recovery and system partition needs to be saved. But saving all the partitions never hurts. After you have followed the information in the link and saved the partitions you can move on to rooting the device.
One serious warning I have NOT been able to write anything to the device using the Android Tool. It always give me an error and won't even try. The backups we create can be used from within the tablet to restore it later if needed.
Custom Recovery Overview:
1) Root device;
2) Download the image file on the tablet;
3) Flash the recovery partition with the image file.
Tools Needed:
1) KingRoot;
2) Terminal Application;
Root Device:
The device rooted using KingRoot. Startup the tablet and go through the setup process. Download the apk from the link provided. The version used in testing was 4.6.2. You will need to allow "Unknown sources". The app will eventually give a button just try to root. This will eventually work and the tablet will be rooted.

It seems the boot issue is still there. Do you ever get this? It will get stuck at the PROSCAN logo display.

I have had it stuck. It was when I was testing things. I can't remember what I did. I do know one time I left it for a day and I noticed the ProScan logo had a flashing cursor in it.

I've been fiddling with it and it seems to be completely random. So I guess it's something we'll have to live with.
I bought it for my 6 year old who's dying to play Pokemon Go. The app runs okay on it. It's just the 'GPS' (or lack of a proper GPS chip) that's a bit slow/inaccurate
Hello I to bought this tablet in Canada I successfully rooted it but is there a reason why no other cameras can be downloaded or Music players or Instagram.
Is thee any chance to unbrick this tablet?
I have one stuck in the boot logo, hard reset wont solve, is there any flash file?
Hellooooo !!

There is a way to create an SDCARD and it will run from the SDCARD. I've forgotten how . I'm looking at one of my kids cracked ones right now. The touchscreen is cracked so I'm looking at build Ubuntu for it. I'll post when I figure out the SDCARD again.
Reset tablet to factory
I was able to use the factory irmware to reset the tablet from a computer. It will over write any custom recovery, etc. I have been unable to recreate a custom image any changes make the image fail. I found the software I used to create a bootable SDCARD but I can't get it to work keeps failing on creating the MBR. The software was the Rockchip SD Firmware Tool and there is an option to create SD Boot. So far I can only find v1.43 anyone have v1.45?
Let me know here as soon as you just remember anything related to this.
I got another tab like this, screen cracked and I could read off its firmware, so I now have a working firmware waiting to be written...

How did you flash the image? what software did you use,
Thanks.
it's not possible to change the rom or custom image of the tablet to another operating system like ubuntu or linux. It has allow OEM bootloader unlocked in the settings in developer section greyed out and it doesn't allow oem bootloader unlocking 'enabled'. You cannot enable it.
What you are doing is just resetting the factory image. or rom. you can just push the reset button with pin after charging the tablet for 3 hours.
These tablets are not 'cheap' to make and google, cell phone companies subsidize these 'cheap' tablets. so you have to use and pay them when you subscribe to their cell phone 'service' or google advertisements when you use their 'service'.
Lots of vaporware being pushed saying they can unlock something for $40 or downloading tools etc. wasted of time as it's impossible to unlock oem BOOTLOADER if the manufacture has locked it, you cannot install another operating system in the tablet, or smart phone. so don't waste your time.
Only some phones allow oem unlocking bootloader and those are the higher end phones costing $400-$600 for a tablet that are not 'subsidized' by google or you cell phone company as with 'cheap' phone or tablet.
the firmware is not available for download at the manufacture website that should raise alarms about the firmware. I've factory reset the device and now it's having reboot issues, either the firmware is defective or corrupt bootloader etc. The manufacture proscan seems to be selling the devices yet no technical support or even a direct download from the manufacture, downloading firmware from thirdparty servers is security risk. it seems like today lots bogus websites and no technical support from manufacturers in tech devices they sell. and people have to sites like XDA for 'free' technical support. Even Microsoft which makes billions in profits fail to provide proper technical support for some reason. and have to rely on 'free' technical support for bugs and issues with their software and hardware and lots vaporware apps etc.. bogus apps. that don't work.
Rooting gives the user the ability to install and change OEM software. from what i gather so don't waste your time, to root a device, allows the user to delete operating system files. if the manufacture doesn't allow changing the oem software there is nothing you can do. about so don't waste time trying root it or try to install ubuntu or linux on the tablet or smartphone if it's oem LOCKED. bootloader. you cannot unlock it. it's much harder to unlock oem software.
the method to 'restore' factory image or known as 'flashing the rom'
there is no reason to flash the rom etc.
1. just hold the power button and esc button at the same time
2. release the power button wait 2 seconds
and then release the esc button
you should now be in boot up mode.
this unit doesn't allow you to be in bootloader mode. so you CANNOT install another firmware or install linux etc. other than the proscan firmware.
3. press esc to select restore the factory settings
4. press the power button to select
this the easiest way to restore stuck in browser or need to flash the rom
again if the rom is 'corrupt' which is not likely
if that is the case
the option to "apply update from external storage" doesn't seem to work as you cannot mount to flash the rom and reinstall the .img file from the .zip file
"apply update from external storage"
where you saved your .zip doesn't work
the apply updated from ADB works you need a usb computer hooked up to you computer and terminal command to ADB to your table to rinstall the .imge file
update ,this no longer seems to work in installing the .zip file method to install the firmware.
lot of software and hardware that have no technical support or documentation and the stuff just doesn't seem to work and high security risk with no updates from manufacture as it cost them money to resolve issues. selling disposable technology tablets. that is not meant to last. basically toys. for kids.

[ROOT][FIRMWARE][BOOTLOADER][RECOVERY] RCA Viking Pro (RCT6303W87DK) One Stop Shop!

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)

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...

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.

Chuwi hi9 Pro unlock, root, TWRP, etc.

If you dont have full ROM backup from your device or official ROM, dont do anything in terms of modding but to install vcom drivers (in my case they wont work without Virtual Serial Port Drivers) for bootloader, and adb/fastboot drivers, make sure theyre working, install Miracle Box / SPFlashTool (or similar ?) to be able to backup/flash your ROM/partitions from/to your device.
Check if it works for you (ie backup your ROM and try to flash something (cache) back.
Now when people are scared enough I want to tell you that it is almost impossible to kill (brick) your MTK phone, it happens mostly when people flash something that is not suppoused to be flashed (something from another device), the worst case if you flash wrong preloader or erase preloader but even after this there is a chance for resurrection. it takes time and efforts though.
++++++++++++++++++++++++++++++++++++
This is TWRP 3.2.2.0 recovery for Chuwi hi9 Pro.
Partitions available for backup:
boot, recovery, system, vendor, data (not incl. data/media = internal sd), cache and "para" (if you have got "recovery loop" - flash "para")
.img flashable - boot, recovery
look for detailed instructions for coomon things in other treads, like
- how to install bootloader vcom drivers and adb / fastboot drivers
- How to work with adb / fastboot command from your computer cmd window.
- how to use Miracle Box / SPFlashToll
This is detailed instruction how to make SPFlash backup out of your phone though Miracle Box does it in one click (well, almost)
- how to unlock bootloader (fastboot mode)
- how to use toilet paper (manual mode)
- how to install twrp recovery
- how to root
Unlock, Install, Root in one post
++++++++++++++++++++++++++++++++++++++
So, main point of this thread is TWRP, youll need:
- roll of toilet paper
- spflashtool backup (just in case)
- backup of your data (if you care) - your data will be erased during the process.
- unlocked bootloader
- twrp image
If something went wrong (highly unlikely), but "if".
Worst case scenerio: your phone will not boot into system / recovery
Solution: reflash (fastboot or flash tool): boot / recovery / system
Worst case scenerio: flash factory ROM (SPFlashTool)
Steps to do when you have all knowledge and all files ready.
IN YOUR CURRENT SYSTEM
In settings->System->About tablet -> click several times "build number" untill you see message "now you are developer"
In settings->System->Developer options: Enable USB debugging and OEM Unlock, connect cable
REBOOT INTO FASTBOOT
Power off, Power on holding "vol+"
Youll see black screen with 3 strings of menu (very small font):
- recovery
- fastboot
- system
use "vol+" for navigation, use "vol-" to confirm your choice (fastboot)
OR from your pc cmd window (shift+right click on adb folder -> choose "open command window here") type: adb reboot bootloader
press Enter
UNLOCK BOOTLOADER
on your pc (if cmd window is not ooened yet: shift+right click on adb folder -> choose "open command window here") type: fastboot oem unlock
press Enter
watch your phone and pc screen for messages
if you have vision problems, make sure you have a magnifying glass.
INSTALL TWRP
download hi9pro_twrp.img to your /adb folder
from the same cmd window type:
fastboot flash recovery hi9pro_twrp.img
*
Reboot into twrp and flash Magisk
*
Basically this is it
There is no command from fastboot to reboot into recovery (correct me)
You can power of, power on holding "vol+", choose "recovery" from menu
command to reboot into system: fastboot reboot
+++++++++++++++

Infect_Ed has posted TWRP recovery that he has compiled from source. DOWNLOAD FROM HERE
We don't know how to make twrp recovery work with encrypted data partition.
Read next paragraph if you are OK to trade security (encripred userdata) for functionality.
++++++++++
==========
In case you want to have your userdata decrypted (and full functional twrp), use following steps:
*** Please, note all userdata AND internal SD will be wiped during the process***
If you care
Save Internal SD card content to your ext.SD or computer
Make a Titanium backup of user apps (check Enable external data backup in Titanium settings)
If Titanium fails to write to your ext.SD than change Titanium backup folder location to int.SD
and after backup is done copy Titanium backup folder to ext.SD or PC.
Disable any passwords/pins from Settings->Security & Locations
(I know they are stored in /data/.. and will be erased anyway but just in case)
- Reboot into TWRP
- ftom TWRP -> Wipe ->Format userdata -> Confirm with "yes"
do not reboot into system
- flash encryption_prevener_hi9pro.zip to prevent system automatically encrypt userdata (it is used to insert modified fstab.mt6797 into vendor/etc)
- reboot system
- restore your int.SD content and apps
============
Link to official ROM/Firnware
*** Read this if you have Recovery Loop - no matter how you boot (buttons, from twrp recovery or from adb/fastboot shell) your device you always end up in TWRP recovery ***
- download 2018-09-29--para.zip
- unzip it - there is a folder 2018-09-29--para with 3 files inside
- connect your phone in twrp recovery mode to your computer
(you may need to turm "enable mtp" option in TWRP->mount)
- copy that folder into your sd card, the path is : TWRP/Backups/Hi9Pro
- click "Restore" (on the next screen make sure ExtSD is chosen as backup path)
- check checkbox "para", run restore, reboot
explanation: para is a partition contains last issued kernel reboot flag(command), like "reboot to recovery, reboot to system, etc." I think there is one flag that tells to kernel something like "reboot to recovery, do something untill its done", since this "something" never done, device reboots into recovery over and over again. This happend to me when I tried "factory reset" command from android settings, so android have sent my device into recovery mode where that "factory reset" command had to be performed but never done because its now not stock recovery but twrp.
**** If you have following problems:
Unknown Baseband -> Unknown IMEI -> NO sim card -> NO cell network
Look here first
****
***** If you came here from there.*****
and you are following their instructions, please, note, step 7. Unlock bootloader : DO NOT DO command "fastboot flashing unlock", just skip it.
Also, try to avoid "fastboot boot recovery.img" command to reboot into recovery (just use physical buttons for reboot). I'm not sure but something caused "recovery loop" in one case at least.
****** back-to-encr.zip if you want to encrypt your decrypted userdata (original fstab.mt6797 will be flashed, no data loss, you will not be able to mount userdata in TWRP, first boot may take long time due to encryption process - 10-60 min- depends how much data do you have)
******* twrp_recovery_chuwi-hi9pro_infectEd-XL is same Infect_Ed recovery adopted for our screen.
Hello. I made a mistake last week. I flashed accidently twrp with a scatter File from the HI9 Air through the spflashtool on the Hi9 Pro. Now it doesnt turn on etc. Is it hardbricked or can i still get it back to life?
No, its not complitely bricked if flash tool still recognizes your phone in bootloader mode. Most likely youve made same mistake I did. Depends of how you flashed that recovery - recovery only or full sisyem WITH new recovery. most likely you flashed only recovery partition. than, first, try to reflash backed recovery & next to recovery ("para") partition. in "download only mode" therell be an error "pmt has changed" than try "format & download" and "firmvare upgrade" - use scatter file contained only those two partitions. if you didnt make a backup ill put here that "para" partition and you can use hi9pro twrp img. in case this wont work, you may want to reflash the whole rom. We need to find factory rom image (from Chuwi or someone who did a back up prior he entered his credintals - thats another mistake Ive made Ive dumped a rom with all my logins information). if I have time I'll try "factory reset" to make a backup from "clean" system.
again, its almost impossible to brick mtk completely. even if flash tool doesnt recognize you phone (dead battery) there is a jump-pins method.
upd. Just looked @ Air scatter and found that Air recovery partition size is same as Pro (~16mb). now I dont know haw was that possible to overwrite next to recovery partition(s) and I think I used same Air img as you did and I've got size warning message when I flash it. anyway here is archive with scatter for recovery and para. just add twrp hi9 pro recovery (rename recovery.img to recovery.bin) and try to flash.
I didnt made a Backup (stupid me) i flashed the recovery file with a scatter file. When i plug the device in the pc the USB sound comes and its recognized as MEDIATEK USB PORT (COM8), but its removed automatic (USB Sound for disconnecting) The Screen stays black. So i have to wait for a Rom and a scatter File then?

I tried your idea. I got an error Message: "Status Preloader Invalid" The Preloader File Format is invalid.
you know how to use flash tool , first you have to press "download" THAN connect usb cable.
but this is a good sign (pc recognize something), you may want to google for something like "unbrick mtk 6797 sp flash tool" for more info
this is archive w. 4 1st partitions (incl preloader)
Ive gotta go. Dont smash your tablet its 100% repairable, well 99.999%
thats how it looks

Still get an error Message for the PRELOADER. I read some Tutorials and dont find a Problem in my setup or my doing. Sucks :-/ But Thank you very much for your help
is it "MEDIATEK USB PORT (COM8)" appears for a second in the devices tree or "mediatek preloader usb vcom (android) (com8)"
if second, then everything is OK with the connection.
if its exactly MEDIATEK USB PORT (COM8) then there is something wrong
try to connect cable with diff buttons combination, i.e. "vol+" + connect cable .
try different "download agent" (DA_PL.bin ?)
Though I also used AllInOne_DA and flash tool V.5.1728
also, you might find Miracle Box Tool is easier to use
try "read" option first to backup your current rom
View attachment 4598709
I shoul ask this first:
- have you ulocked bootloader ?
- when your press "power" and "vol+" after some wait is anything appears on the screen
(boot menu: fastboot, recovery, regular boot) ?
- when your press "power" and "vol-" after some wait is anything appears on the screen
(chinese written) ?
Good Morning.
Bootloader is unlocked, no matter which key combinations ill try the screen stays black. When i have the usb cable at the PC (no matter which Port or cable) it the plugin - plugout sound plays every few seconds/minutes (not the same time in between). It is recognized as "MediaTek USB Port (COM4)" (different PC i tried). When ill try to install the vcom drivers i get the message that the best drivers are already installed and that are the mediatek usb port driver.

zelipukin i made a short Video about the behavior. The Device seems to activate when i push vol+ or power, but it looses connection when i stop holding the button or sometimes even when i hold the button.

...thinking
Just tried...seems like backups I made(and posted here) from Miracle Box is incompatible with SP Flash.
SP Flash doesn't like this and doesn't like that when tries to restore those backups but Miracle Box restores individual partitions or whole ROM w/o problem.
SP Flash is so inconvenient if you try to make a backup ... its also inconvenient when you try to restore.
Where did I get that Miracle Box for free ?
Let me figure out something...
....
This is something beyond my understanding but let me to describe what I did
- in SP Flash I choose scatter file and recovery.bin (like I sent to you)
- download only - no go
- download+format - no go
- firmware update - warning message about wrong partition size or something like this - Ignored - Flashed
- Bricked again (like yours - black screen - that's it)
- OK, I have several backups. Tried all of them - none of them works... except one
- Flashed that backup with SP Flash - no questions, no warnings, no errors - device came alive
- Flashed only recovery.bin - everything went fine
- Tried to find difference btw different backups - but couldn't find any
- So I tried to flash those files (to try 3.zip) several times and everything went OK, so this is 100% working backup.
Try it and see what happens, then we can go somewhere else. I still suspicious about those MTK Usb Com(8) instead of preloader usb. Also if you used "Firmware upgrade" option once, I beleive you'll need full ROM flash. Keep looking for it @ Needrom.com.
Strange things happen. Couple years ago I lost MTP connection with my MiMax. I tried everything possible but no luck - have to use UMS Enabler so I can read/write ExtSD at least, but MTP works with Chuwi.
I spent numerous hours trying to connect Chuwi in preloader mode until found that solution about Virtual Serial Port drivers.
Thanks for your help so far. Seems like my Device is half dead after 2 Hours of use
I'll tried to change the Drivers for the mediatek, it shows the device now with the preloader, but i think it doesnt work right. when i change the usb port it comes back as MediaTek USB Port (COM4). I made you a 15 Second Clip of the behavior.

Really weird. :-/

and no chuwi hi9 pro rom at needrom yet. :-/
Sorry, haven't seen there is second page of this thread.
Saw a video where one guy showed how he changed drivers to right ones.
Main idea is in that short period of time when wrong drivers appear click right mouse button and choose "uninstall drivers"
after this in his video in next attempt system found usb vcomm by itself. worth to try
or other videos where guys catch a moment when this port appears in device tree but choose "update drivers"-> "browse my computer..."-> "let me pick from a list of device drivers" -> remove flag from "show only compatible.."->
I cleaned system, removed apps,accounts, etc. and made a backup of a "clean" ROM (well, almost). will put somewhere when/if I get good wifi somewhere (its 3GB.. w/o data partition) I'm on slow & limited mobile network.
but I don't think you need anything but recovery & para if you never used "format" & "firmware upgrade"
i think i used the upgrade one, after download only didnt work.
Ill tried the same method with changing drivers.
I will sit this one out, till you have uploaded the rom
Thanks for helping me out!

Just a few questions after using Hi9 Pro for about a week:
1) Where is the microphone ? Is it the small hole under the volume button ? (Strange position)
2) On the back side the two metallic stripes separating the plastic of the metal body are they something like antennas ? (LTE or WiFi or both ? )
3) What is the version of Bluetooth ? (4.0 or 4.1 or 4.2 ? )
4) Is it possible to use some kind of fast charging with a suitable charger or software app (firmware update) ?
MediaTek has a technology called "Pump Express" or something like that...
5) Do you have sudden, unexpected pop-ups of full screen advertisements while you are working with your tablet ?
How do we get rid of them ?
6) How do I find the LTE band the tablet is actually using while it's in use ?
I don't mean the table of supported bands, I mean the active band while using it.
Thanks!
1) looks like and its logical bc its close to mouth than if they put it in the bottom.
2) not sure, but most likely
3) according to this https://www.manilashaker.com/mediatek-helio-x10-vs-x20-vs-x30-chip-comparison-difference-specs/ its 4.2
4) too many different opinions, cant find the truth
5) none so far
6) you can try to find some info from mtk engineering mode *#*#3646633#*#* from you dialer
but its not intuitive and complicated

Yes, it is a very small hole at the bottom right as you hold it, with a size of the edge of a needle!

But how did you do that ?
Did you add an Ad Block after rooting the tablet ?
The kind of ads I get, is more of suggested apps to install from Google Play.
It is literally bombarding me with an exhaustive rate.
I went to settings to "advertisements" of Google and it says that I can't turn it off.
Could it be some app that I installed that is spamming me this way ?
Can you suggest something to stop it ?

I installed LTE Discovery and although I'm not rooted it seems that it works OK and it's showing me the bands.
The signal strength is lower than a mobile phone at the same position, same time, same provider.
Do you have an equal signal strength like your mobile phone ?
One more question:
7) Is it feasible for a developer to build a custom ROM for this device if he wants to or there are certain restrictions forbidding custom firmware ?
Is there any chance for a custom ROM in the future, because I don't think Chuwi will upgrade to 8.1 or better Android.
Thank you!
Regarding ads - I didn't do anything, I looked @ settings->google->ads and I can turn it on and then off w/o problem
Also I culdnt find any junk software so far, the phone came from GearBest factory sealed. I didn't do any system modifications except installing Magisk and modules - ExCard Access Enabler, init.d injector, Magisk SELinux Manager, ViperX (slightly better sound from speaker)
I didn't try the device as a phone, though it fit in a pocket of one of my jeans. I'd like to try but my current phone (miMax) has a micro sim.
7) Depends how popular is this device and who (developers) got it. Also, depends if this chipset is used in many other similar models (popular, prefferable) than you don't need to be a real "developer" to port ROM from a similar device and if you find that divice X is updated to 8.1 there is a chance someone will make a port (or you can try to do it yourself). I'm not a big fan of immediate upgrading to a newest version, for me they usually bring more limitations (you cannot let apps to modify files on your own sdcard f.e.) than benefits. I still use >2 y.o. andr. 6.0 custom rom on my MiMax.

Me too, I got a sealed and clean tablet from GearBest but If you look closer to that setting, it says that you can turn on or off the specialized ads for you, but you can't close ads completely.
For example, during web browsing do you see ads inside various sites ?
Or when opening apps on your tablet ?
I think we need an ad-blocker for this.

I meant for mobile 4G data, not as a phone.
In my country we have three bands for LTE:
B3, B7, B20.
When the tablet rotates between 3 and 7, I have poor to zero signal.
But I saw with LTE Discovery that when it switched to 20 then the signal is very good.
So, with the help of MTK Engineering I disabled 3 and 7 bands and everything seems OK now.
I hope B20 to be used everywhere near to me.

I'm not familiar with Android internals so much, I am only using a Note II with TWRP and a custom 7.1.2 ROM and I'm missing some simple customizations not available with out Oreo 8.0 stock ROM.
I haven't even tried yet your first post regarding rooting and all the others because I'm not so sure where to find these tools and how to use them.
It could help a lot when you find some time to add more descriptions and links in your first post, if possible like Hi9 Air thread.
Thank you!
I dont know how and why, but I dont have any agressive advertisements. Checked Opera I'm using for webbrowsing - even "block popups" option wasn't checked. Had to download app yesterday (AutoNotification) from gp store and when I started it in a "free mode" there was a message like "to use this app in a free mode you have to agree to see ads", clicked "ok" , then message "downloading..." appeared...and nothing, no ads. I connect my tablet to the internet through my phone but dont think that matter.
Just a few more short questions:
8) Is there any other way to wake up the device instead of pressing the red button ?
For example double tap or maybe using the volume buttons or any other way.
Because I'm afraid of pressing the same button again and again.
9) Does this device have a WiFi 2x2 MIMO ?
I haven't found any particular info on this.
10) What is the kernel of the ROM ?
Is there any GUI compatible like Kernel Aiutor to make changes or take a look at info for the device ?
Thank you!
