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.

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
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
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

Restart to recovery/bootloader don't work. The tablet restarts to OS in both cases. (dev menu -> advanced restart)
I'll post more bugs as I'll find them.

It doesn't connect to hidden SSID wifi network. when adding a network there's an option to specify that the SSID is hidden or not.. :eek:
Rotate lock screen isn't present in Settings but it appears in Search.
Ethernet connection doesn't work.

I have upgraded from latest 15.1. Some observations:
  • Vibration does not work for me in the initial 16.0 release.
  • Longer wake up time (i see it's fixed in new built).
  • I also didn't realize 15.1 gapps are not compatible with 16.0 so after upgrading just the LOS I experienced gapps crash fest. It's better after installing MindTheGaps9 but now launches and crashes some silly Pixel Phone wizard app on almost every transition to home screen, preventing opening home screen. There is a workaround getting to home screen by using history button and clicking on background. Some apps failed to start, like Youtube but reinstallation healed the issue.
  • System seems to be nice, smooth and responsive. Very nice upgrade.

Thank you. The 15.1 built was amazing already.
Do we have to flash new gaaps when upgrading?

Of course.

Upgrade process should look like this:
- create a backup!!!
- wipe system, cache, dalvik
- flash los 16
- flash open gapps for pie (i use Pico)
- optional: flash your root solution (I use magisk)
- sign boot
- reboot

Hey dude, thanks for your great work, everything's working fine, but I have a problem when try to screen mirroring to my tv because every time I do the tablet crash and restart... Can you fix it please? In lineage 15 doesn't have that problem. Thanks in advance.

Man, you are a legend!! Working great!! Thankyou sooooo much!

In regards to vibration not working... Mine is working but it is very light when say pressing home button. Working but much lighter vibration than before.

I use Gboard so I can just increase that vibration fine.

Thanks again!!

Guys, can you find "ambient display"? There's no option in Setings> Display, but if you search in Settings, 2 results appear with no use unfortunately :(

There's a LiveDisplay in settings. I think it's the same thing.
Well, I just want to have the display turned on when a notification arrives.
LiveDisplay is Day/Night color tweak etc... Ambient Display is that option to have the display turned on when notifications arrive/ when you pick up the tablet etc.
The weird thing is that if you use search in settings, you can see that the option is there somewhere. But when you tap it you go nowhere :eek::confused:

Ah sorry. I've never used Ambiend display before and I tought that they might be the same thing.
Same bug with Rotate lockscreen.


If anyone find a Google Camera app that works, please post it in the topic. Thanks

I noticed that not all notifications from twitter appear with this ROM comparing with 15.1... So I thought I could return to 15.1 by wiping Cache/ Dalvik/ System and flashing the Oreo ROM + Gapps. Unfortunately Android started booting but ended up in TWRP. Most probably full wipe is needed.
So I decided to flash Pie again! I wiped cache/ dalvik/ system, flashed LOS 16 + Gapps, rebooted.. this time it booted to Android normally, but now I have no notifications from any app at all! Yikes! Any clues guys?

Good morning.
Thanks for all.
I have a problem. I installed the new LineageOS 16.0 but the wifi does not activate. When active it is deactivated by itself. Thanks for your help.
