Anyone willing to improve this version further? It's still getting bugfixes according to the changelog https://www.lineageoslog.com/14.1.
And maybe update the kernel as well.. I've tried all the other versions for this tablet and always come back to this one as I found it to be the most stable.

Hello hope you'll be fine.
Wanted to ask about the battery life and performance of LOS 14.1 as I'm running LOS 16 currently and it drains battery alot with gaming (PUBG mostly).
Want your opinion on stability, battery and performance.
Will switch to Los 14.1 then :rolleyes:

     * 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.

    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.

    • Its probably final build for Lineage 14.1, next will be 15.1. Some final preparations done:
    • Removed some unused blobs
    • Fixed grayish colors in HAL3 camera app lik Google Camera mods.
    • LineageOS code updated
    • Device tree switched to subtreeway to include some needed caf modules like camera., gps, ipa. If you use sources please note cm-14.1 branch force pushed. Old branch saved to cm-14.1-backup
    • ROM installation process changed. Now works with encrypted /data partition. No need to format data when coming from stock ROM. Please use new TWRP build with Boot Sign function, download below..

    How to install
    To install this you have to install TWRP using by QFIL utility, follow this instruction: https://forum.xda-developers.com/general/general/twrp-lenovo-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:
    2018-08-25
    • Fixed long time to wakeup screen in TWRP
    • Added NTFS filesystem for sdcards

    gdrive: twrp-tb8703-3.2.1-20180825-bootsign.img

    Previous version

    This TWRP build has special function Sign boot whihc 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
    Code:
    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
