LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (pie), 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.

[*] Первая версия

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
