* I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...).
* Please do some research if you have any concerns about features included in the products you find here before flashing it!
* YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.
* Your warranty will be void if you tamper with any part of your device / software.
* Same statement for XDA.

LineageOS is a free, community built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

What works:
Calls/SMS/Mobile data
FM radio
USB and WLAN tethering

How to install
To install this you have to install TWRP using by QFIL utility, follow this instruction: https://forum.xda-developers.com/ge...vo-p8-tb-8703f-tb-8703x-t3689442/post76277192

Special TWRP build
To install and boot any custom roms and to boot it after installing mods that change boot partitition like Magisk please use this TWRP:
  • Fixed long time to wakeup screen in TWRP
  • Added NTFS filesystem for sdcards
mailru: twrp-tb8703-3.2.1-20180825-bootsign.img
gdrive: twrp-tb8703-3.2.1-20180825-bootsign.img

Previous version

[*] Первая версия
mailru: twrp-tb8703-3.2.1-bootsign.img
gdrive: twrp-tb8703-3.2.1-bootsign.img

This TWRP build has special function Sign boot which you have to click after install new version of ROM or mod like Magisk. It will append stock boot signature to your boot partition. This allows to boot with locked bootloader.
TWRP with Boot Sign function screenshots:

Fortunately you dont need to unlock bootloader, because not every Lenovo tab can be unlocked. Custom kernel and ROM can be runned by appending boot.sig signature extracted from stock rom to boot.img like
cat boot.img boot.sig > boot-signed.img
It still cant be loaded by fastboot, but you always can flash it from TWRP. You can get boot.sig in my repo https://github.com/HighwayStar/android_device_lenovo_TB8703/blob/cm-14.1/twrp/recovery/root/boot.sig

I tried to flash this rom and other versions (Lineage 16 and 15.1, and PE). What I got is looping at boot animation. I flashed TWRP 3.2.1 with bootsign and another version in [TWRP][Root][Guide] Lenovo P8 (TB-8703F and TB-8703X) but nothing changed. Is any step missing? I have clicked the boot sign option after flashing roms.

Solved by reinstalling stock firmware. It was caused by formatting SYSTEM partition in TWRP. It's not necessary so don't do that. Flashing custom ROM directly.
