Look if you want to upgrade your tablet to a newer version of android,I suggest LineageOS 14.1 Deathly kernel,you should root your device by SuperSU addon so you can change the kernel of your device to maximum performance,the only bug I found was the charging time,I think it takes more hours to be fully charged,but LTE and fingerprint are both working and graphical glitches are fixed.
The only stable rom I know,but I still hope that the LineageOS 17.1 bugs get fixed,that rom is nice too,the dark theme and accent colors are beautiful but unfortunately mobile data doesn't work and Kernel Adiutor doesn't work well.
Can you give a list of bugs in lineageos 17.1? just 3g data and overclocking and thats it? then it is mostly good for the wifi versions(t700 and t800).

-No mobile data
-Kernel adiutor doesn't work (I can change cpu and ... settings but after I exit the app and enter it again the settings are gone.)
-After I power off the tablet or restart it,the fingerprint, password or pin takes a little while to work.
-I can't change network operator
These are the bugs I've noticed.
I think if someone could fix these bugs the tablet would go on several years.

8224Freak Thanks for this.

My T700 is running 20220505.010526 and it has breathed new life into the tablet for the ( few ) applications I run. These mainly being Kindle, Prime video , gmail , youtube and Chrome .

Only issue I have come across is as Armin above says, after I power off the tablet or restart it,the fingerprint, password or pin takes a little while to work.

Some questions :

1. Should I update to one of the newest builds ( are there changelogs that may help determine if they will help ?
2. Are there any logs that may help, if so I can attempt to obtain them ( ideally via an app install )

I used to use 14.1, but with the applications I use this seems more stable, so thanks again

regards

Well it would, as a wifi-only tablet with no password protection,

You can update to the latest build and see if anything had changed. You can take logs via executing adb command ‘adb logcat’ as soon as you try unlocking your device with fingerprint password and pin whatever

Thanks. With latest build I reboot, wait till screen goes black, press home key then unlock and all ok.

Happy to regard that as fixed

regards

If someone is trying to debug this android 10 based rom for sm t805,he should consider the bugs below:
1) mobile data
2) network operators
3) password,pin or fingerprint not opening the tablet for about 15 to 20 seconds after booting up
(I think CrDroid Android 10 is better to modify,because you wait while bootup animation is played and after that password,pin or fingerprint works)
4) kernel adiutor doesn't apply changed settings
I will be grateful to that genius guy who fixes these bugs.
Thank you guys!

thank you for the link, its been a few years since i played with roms and twrp etc. time to dust the skills off. thanks again
Hi guys me again it has been a while, is there an installation guide handy for this installation, i have used Odin before and that is fine, so an install with that method would be handy thanks again.
Sorry in advance if it has been covered before, but it has been a long time, I dont particularly want to Root it , too messy and I only need basic internet wifi nothing too fancy. thanks

Tested today lineage-17.1-20220619-UNOFFICIAL-chagallwifi. It is an improvement w.r.t. the older versions, where video in browsers (Brave and Firefox) had scaling faults. Unfortunately, SELinux is still "permissive", and still no encryption. Without SELinux Android is just a toy, where any application can spy on the data belonging to any other application.

So, I am back to the good old lineage-14.1-20220107-UNOFFICIAL-chagallwifi again.

BTW, I made T-800 run significantly faster by sticking multiple layers of aluminium adhesive tape to the processor heatsink, thus spreading the heat all over the batteries and frame - nice!

The battery connector gets bad and solders cracks resulting overheating but i guess there is some other going on too... i attached long copper sheet with heat pad top of cpu/gpu/ram chip hamburger and now been running cool.

Did anyone install Magisk lately on to this? I guess Magisk installation has changed on these again.

Update: Figured out, when from LineageOS zip file i took boot.img file and did ran through newest Magisk from github to patch it.. i renmabed it back to boot.img and i had use gnu tar from command line (no matter if windows or linux) but on 7zip i got slightly error in tar file header (zeroes where should not be zeroes).. i saw this as slight cryptic characters in ODIN when doing flash.. so if someone does install gnu tar and uses it..

tar -cf boot.img.tar boot.img

Then in ODIN put this new *.tar in AP and flash.. success.
