LineageOS is a free, community built, aftermarket firmware distribution of Android 8 (oreo), 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.

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
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 likeIt 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.sigCode:
cat boot.img boot.sig > boot-signed.img
