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/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

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

Nice to see this ROM here on XDA. Very good job! Running it for a day now and cannot find any problems with it (except notification LED and backlight sometimes too dark)
Battery life is very good. Light and Deep doze (deviceidle) are working good.
For a first release this is very good!

Is it possible to add cpu hotplug to the kernel, and cpu underclock?
Add core_ctl ?

Looking at msm_performance.c (also hotplug capable?) it looks like the CONFIG_MSM_PERFORMANCE_HOTPLUG_ON flag is not defined.

No big deal.

Cheers

Some bug: if the screen locks I can't unlock it again without restarting. The lock button doesn't light up the display, I can use the volume keys to lighten it up but if I try using the touchscreen the display goes dark. Just one touch and it goes dark.
edit: the touchscreen responds while the display is dark, for example I pull the status bar down, and then the display lights up and I can enter settings, enable/disable wifi etc.., but once I go to the home screen the display goes dark.
edit2: found the problem. Changing the wallpaper to something that's not in the rom by default.
edit3: problem went away after installing 28-05 firmware version.

Would this run on a Tab 3 8 non-plus? If not are there any roms out there for such device? Or anything in general to make it faster? Thank you.

Having trouble getting it to work on mine (wifi model - 8703F)
TWRP went on fine (and thankfully I took a backup at that point!), then I install the latest version (lineage-14.1-20180528-UNOFFICIAL-TB8703.zip) and run RM Forceencrypt and reboot. It shows the Lineage progress bar for around a minute, then just turns off.

Tried with and without forceencrypt, restored from backup and then tried again but no luck... Going to go back to the official ROM for now, but if anybody has any pointers for the next time I try it that'd be great.

Kudos to highwaystar_ru for all of the hard work!

Which wipes did you do before installing?
 
Well, this rom is fantastic. I've tried a few over the years and never has one made such a difference. The stock rom must have been an enormous pile of **** lol. I mean how do they go through so many firmware iterations and still leave simple problems unaddressed. Anyway, I digress...

On a couple of webpages I noticed slow loading in Chrome eg https://www.gearbest.com/laptops-c_11964/

So I ran a logcat which picked up some interesting errors which might be worth looking at even if they're unrelated :)

Thought that I only did cache and data, but I guess I must've selected something else... Wireless is totally broken on it now after restoring ^_^

Going to do a full recovery now and start from the beginning (and pay a lot more attention this time!)
