This is LineageOS 16 for both versions (LTE and WiFi-only) of the Samsung Galaxy Tab A (2016).

All work for this ROM was done by @Valera1978 - I only did the builds based on the current LineageOS sources to make the security fixes available for this nice ROM. So all thanks may go to @Valera1978.
You find all discussion to this ROM in @Valera1978's thread here: https://forum.xda-developers.com/galaxy-tab-a/development/rom-lineageos-15-1-64bit-20180920-t3845016

Downloads:
Latest builds from 2021-12-20 with security patch level 2021-12-05.
The builds can be found here:
SM-T585: https://www.androidfilehost.com/?w=files&flid=307678
SM-T580: https://www.androidfilehost.com/?w=files&flid=307673

Migrate-script: https://www.androidfilehost.com/?fid=2188818919693800974
(unzip before use, identical script for both SM-T580 and SM-T585)

Please make a complete backup with TWRP of your current ROM and data, in case anything might go wrong!

The builds are signed with release keys!

If you want to install this ROM over an existing installation of another author's Lineage-OS (build with test-keys), then you first should run the 'migration-achalmgucker.sh' script with the argument 'official', to ensure compatibility to my build with release-keys.

And if you want to move from this ROM to another author's ROM, then it might be good to run the 'migration-achalmgucker.sh' script with the argument 'unofficial' to return to test-keys.
Please carefully read this information from LineageOS: https://wiki.lineageos.org/signing_builds.html
Or you do a factory reset before starting with this ROM. (You will lose of course all your data!)

Further updates of this ROM can be done directly without data loss, no special migration necessary.

Gapps
https://opengapps.org
Android 9.0
Platform: ARM64

Root
Can be done with Magisk.

Thank you very much; runs perfect on my t580.
One question: after every reboot I get the warning that Selinux is disabled. Is that a problem, or should I just ignore it?

I also would like to thank and congratulate the developer(s). This ROM is now the only viable option for a T585, since LOS17.1 is practically unusable and Blis broke phone calls and became ridiculously bloated with google crap.

Thank you, I hope you'll be able to keep updating the ROM with security patches every now and then.

For the life of me, I cannot get this to boot on my T585. Tried to use the migrate build to move without data loss. That failed. Tried a factory reset and migrate build again, no luck. Another factory reset and the regular build, no luck. Format and clean install with both the migrate and the regular builds, no luck. I always just get the lineage splash screen animation endlessly. Typically I let it run like that for about an hour before I try another iteration, but I did let it run for 12 hours once just to see.

I've tried flashing with and without magisk and gapps, always the same result.

I started this process off on Valera's 12/11/19 predecessor build, TWRP 3.3.1-0.

Anyone else work through something similar and/or have suggestions for how to get it running?

I'm sorry to hear that.
Do you use Google-Apps? I took the micro package from opengapps.org.
My usual installation procedure (for a first time installation) for tablet and smartphone is:
  • Make backup
  • Wipe boot, system
  • Wipe data if factory reset intended, otherwise keep data
  • Add lineageos.zip, add opengapps.zip, add magisk.zip
  • reboot
That's it.
Subsequent updates with the same ROM flavor are only done by installing the lineageos.zip without any wipes or re-applying of opengapps/magisk.
With one smartphone I have trouble from time to time, it would remain in the Lineage-logo for long time, either perpetual or at least longer than my patience lasts. In this case I force reboot (power/volume-) and most times it works then for this phone.
I have not had such trouble with the T585 and the T580 yet.

Hi,
Thank's for the reply

Yep, that's my typical process too and the one I followed. I use the opengapps.org full build since I'm pretty well entrenched in the google ecosystem. It figures though that this is the one time I forgot to take a TWRP backup before flashing the new rom and this is the one that's causing me so much hassle. Thankfully, I don't keep much user data stored locally on this tablet so its more of a time hassle than any real dilemma.

Just to confirm, since I've done full resets and wipes to try and make it work, I shouldn't need the -migrate build any longer since the old keys are wiped in the format, or are they stored somewhere in the device PROM and so I should continue trying to make the migrate build work? I'm curious if its a TWRP version difference that may be flashing improperly, or if the fact that I have a microSD inserted when I'm doing this might be causing some hangup?

My next step I think, unless you have some other suggestion, is to revert to the old build and start the process over from there with just bare bones.

Thanks!

Too bad! :(

Yes, with factory reset, you start with the normal build, no migrate required.

or are they stored somewhere in the device PROM and so I should continue trying to make the migrate build work?
No.

I'm curious if its a TWRP version difference that may be flashing improperly, or if the fact that I have a microSD inserted when I'm doing this might be causing some hangup?
I also had the microSD card inserted during that process, and I use TWRP-3.3.1-0

My next step I think, unless you have some other suggestion, is to revert to the old build and start the process over from there with just bare bones.
Yes, now, as you already lost all your data, you could try to restore some older backup and check, if everything is working again. Then wipe boot, system, and data and install the (non-migrate) build as a fresh start.
Good luck!

Thank you for this rom. Seems rock solid so far was encountering several bugs on the 10 Roms so a updated pie rom was just what I needed

Maybe offtopic, do you think it's worth to buy an sm-t585 ( used ) nowadays for 120 €? Of course with the sense to flash THIS rom. Thanks in advance...

I personally like this tablet very much and I would pay that money.
However I use it for reading my local newspaper, online magazines, doing much of my e-mail correspondence, internet browsing, Skype etc. But no games, no memory and processor demanding apps.
The display quality is very good, the sound is acceptable. Very good for office-type work, the battery lasts half a week.
And I like the appearance and stability, but I do not have an overview of other current tablets to make a fair comparison.
Just my personal opinion.

+1 for the above. price is cheap and my wife and me love this one. doing same as above, but have both in caes with keyboard, using it for RDP sessios to my Linux Terminal Servers and more office style work. Display is great, CPU power is fine.
