Development [TB-J716F] TWRP for Android 12 / ZUI 14

[f1tm0t]

Hi, people!

Spoiler: Old message:

Porting our TWRP for A12 (ZUI 14.0.127).
Now it's fully working, exept touchscreen. But with mouse connected via OTG you can to do all neeeded operations.
IMPORTANT! The method of decrypting /userdata is not implemented there (different from A11), so you need to install the DFE-NEO patch to make it work properly with your data.
EDITED: New version v5
Added ability adb/MTP on encrypted /data.
MTP works on demand, pressing Disable MTP-Enable MTP, displays SD card only.

UPDATED Febr. 08:
Built a new full-featured version with data decryption from source. For Android 12 - ZUI 14
Decrypts data by default, if the tablet is not protected.
If it's protected by pin/password, it asks for it and decrypts internal storage.
I haven't tried the pattern, see here: https://twrp.me/faq/openrecoveryscript.html (Specific pattern decrypt note), try it yourself.
Device tree lies here: https://github.com/F1tm0t/twrp_device_lenovo_J716F
Many thanks to:

Yahoo Mike - for useful tips on decryption implementation and general support.​

LSS4181 - for Q706F device tree, I used it as a basis for mine.​

Ungeskriptet - for his J716F device tree for A11, it was useful for me.​

TWRP_J716F_A12_DD. img DD means Data Decryption.
Working: Everything, excluding vibration.

PS.
Welcome to collaboration.
I have another variant of TWRP with a malfunctioning touch. The pressure points do not correspond to the position of the buttons. It need to add some calibration files or the right firmware or the right driver for the screentouch. This is too complicated for me I'm just advanced user, no guru.
Please, write me in PM if you can help with this issue.

Nice to see some development for the TB-J716 tablet XD since the developer don't want to release the kernel source/ open source to the public.

 

[Ungeskriptet]

Die you add the firmware for touch to TWRP? I have it like this in my TWRP port: https://gitlab.com/ungeskriptet/and...tree/android-11/recovery/root/vendor/firmware

I suggest you extract the firmware yourself from the latest ZUI, the older versions might not work.

Remember, you can't to backup data before using DFE-NEO patch.
Many thanks to Ungeskriptet for helping.
To be continued (I hope)

New version for ZUI 14 with new features:
* added many partitions for backup/restore
* added some partitions for flashing via Install IMG
* A set of partitions is enough to backup/restore an entire OS

Hello @f1tm0t
The TWRP seems unable to use ADB shell due to ro.adb.secure=1
Could you help to edit that value? I tried many tool to rebuild TWP with new prop but no luck, device bootloop
Thanks

Hello @f1tm0t

Hello, friend.
My TWRP works with adb/MTP quite excellent.
The following is needed:
decrypt /data
permission in the system to debug from this computer

Thanks for your help, I will redownload and double-check again.

Hi @f1tm0t
I re-download and flashed v3 but the same result
Could you help me to check it
Thanks

 

[f1tm0t]

I re-download and flashed v3

I offer version 4: https://mega.nz/file/g4VBnIpC#_4_x0b3V-Z6oSoXDA2xbHSN7hBKXRgjnwfFMLfPcYXA
My version cannot decrypt /data, so you have to install the DFE-NEO patch from TWRP.
After rebooting to OS you must to enable USB debugging, it create adb.key in /data.
And after rebooting to TWRP you can use adb/MTP, because TWRP sees adb.key in not-encrypted /data.

The TWRP seems unable to use ADB shell due to ro.adb.secure=1

Made new version (in the title), adb works by default. Enjoy!

Can this be used in TB350XU (P11 Gen 2) or can it be ported?

Thank you! Do I take your TWRP and do some stuff to it using this guide? Or which TWRP source should I use?

Also, I can't find the stock recovery.img inside the downloaded factory source rom (downloaded from RSA). Where did you find it?
