Hi,

This post is a subject to change (grow), since I will keep it as a record for my tips for this fine tablet.

Installation of TWRP recovery and increasing /data partition (YES! That's possible)

I've succeeded getting TWRP, root and larger /data partition, so after screenshot I'll put detailed how-to. Sorry for duplicating first post, but I'd like to have everything in one place in the way I exactly did it.

Warning: this method seems to be blocked in some newer OS updates, see this post for reference: http://xdaforums.com/showpost.php?p=64801688&postcount=25

You need SD card for that.

Cube T8 Plus TWRP and root:

1. Download SuperSu and copy it to the root of SD card (without extracting): http://download.chainfire.eu/supersu

2. Downlad Utility/Driver to PC: http://uploaded.net/file/eyo5yt8c

3. Download Cube T8 TWRP recovery to PC: http://uploaded.net/file/o54jinin and unpack.

4. Install driver on PC. Depending on Windows version, if the driver installation fails, it may be necessary to disable signature check (google for that).

5. Run flash_tool (downloaded in step 2). If it doesn't run, try copy it to the root folder of your hard drive, eg. C:\SP_Flash_Tool_exe_Windows_v5.1516.00\, albo D:\SP_Flash_Tool_exe_Windows_v5.1516.00\

6. In "Download" section choose "Scatter-Loading" point to "MT6753_Android_scatter" from /Recovery (downloaded in step 3), press "Download" button.

7. Turn off the tablet. Connect it via USB to PC (tablet needs to be switched off!). After short while, flashing tool should recognize the tablet and start flashing automatically, installing TWRP recovery. After that you should get "Success" screen.

8. Disconnect tablet from PC. Run it in Recovery by pressing VOLUME_UP and POWER simultanously.

9. Using VOLUME_UP, choose "Recovery" and confirm it by pressing "VOLUME_DOWN". Wait untill TWRP starts.

10. In TWRP choose 'install ZIP' and point to "/external sd/UPDATE-SuperSU-v2.46.zip"

11. After installation is finished, choose "Reboot". Recovery will hang, but do not fear ;) Press Power for 10s to force turn off. Then turn on the tablet.

Your tablet is now rooted!

Change partition size:

1. Download and copy to the root of SD (without extracting) Resize_v22.4.1-signed.zip: (take attachment from the first post here: http://xdaforums.com/general/rooting-roms/guide-how-to-resize-data-internal-t3180978/ )

2. Run the tablet in Recovery by pressing VOLUME_UP and POWER simultanously.

3. Using VOLUME_UP, choose "Recovery" and confirm it by pressing "VOLUME_DOWN". Wait untill TWRP starts.

4. In TWRP choose 'install ZIP' and point to "external sd/Resize_v22.4.1-signed.zip""

5. In one of following windows choose the partition size. I recommend between 8GB and 10GB. WARNING: If you choose less than the current size, you may loose your data. More than or equal to 8GB is a safe value.

Enabling Multiuser accounts:

1. The device must be rooted

2. Use any root explorer to edit /system/build.prop.

3. Add to the end of a file:

fw.show_multiuserui=1
fw.max_users=5

4. Reboot

Info: After first try to swich to guest the device force rebooted, but then it worked well.

Disabling killing background apps

If you encounter situation in which apps are being killed right after they are put to background (each application switch using recent apps causes application reinitialization), just make sure that Developer Options/Apps/Don't keep activities is switched off!

Permamently disabling pre-installed chinese apps (they will not reappear after full reboot)

There are 6 chinese apps pre-installed, which can be easily disabled. You can try to simply uninstall them, but you'll find that after full reboot they reappear.

So the best way to disable them is to use any root explorer and get rid APKs in /system/vendor/operator/app. I myself renamed app folder to app.old. They do not appear anymore.

What to do if tablet seems to be dead (black screen - no reaction), but it just misbehaves

Couple of times I've had a situation in which the screen was blank and I couldn't wake up the device. I could however run recovery, so the first time I performed reset from recovery and it helped.

Next time I found out that it's automatic brightness that fails and causes the screen to go blank. So the solution is to press power button, make a swipe gesture from the top to show brightness slider (you will not see it, but it works even on the lockscreen), and try to blindly press this slider. It should be about 2,7 cm (1,06 inch) from the top, with ca. 3cm (1,2 inch) margins on the left and right. Then stop using autobrightness with slider set to zero.
