[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
I installed Lineage 19.1 following the procedure in the OP. I loaded the stock ROM version specified via Odin before I started. The installation went well. But there were a few issues with the ROM. There is the issue with the brightness, which I can work around. Having TWRP boot back into TWRP unless you use the exit_twrp command is a PITA. These are well documented on here.

I also found issue with not being able to access files from my PC via USB. I also had a problem with accessing my OTG flash drive in TWRP. These were fixed by installing the SM-T500-GSI-kernel.zip file I found in another thread on here.

But my unresolved issue is with charging the tablet when the tablet is off. When charging, the tablet does not display the level of charge. The circle is empty. In addition, when I unplug the charging cable, the screen stays on this charging display, and will not shut off. I have to press the Power key for 10 seconds to get it to turn off the screen. Anybody else see this issue? It seems to charge normally when the tablet is turned on. I had the same issue with the previous Lineage 18.1 ROM by the same developer.

As a side note, I did try using the Updater in the syster instead of following the update procedure in the OP. It downloaded and installed, and worked! But the update did not include Gapps, and my MTP fix no longer worked. I installed the MindTheGapps and the kernal zip file again in TWRP, and that fixed both, updated to the 5-10-22 version of Andy Yan's GSI.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Hausemaster:
The charging when tab is powered off is common for almost all of us, as, I have the same issue here..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] runswithascript:
I am interested in complete instructions for the most degoogled way to setup this ROM with as much working functionality as possible. Please share.

I see references to setting up MicroG without GApps during install and with, and I have been wondering if the latter means removing GApps post install or how it works exactly. Ideally I would use GrapheneOS but as not an option I would like to get as close to it as possible.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sumur:
Can you still use double tap to wake ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kudalufi:
It's actually not all that hard to get microG on. The pain is that the LineageOS devs are allergic to including signature spoofing, so this has to get sorted first. That's 99% of the pain. Fortunately it's mostly doable with magisk modules:

Install Magisk if you haven't. I recommend version 23. Just copy the magisk apk to the ext sdcard and flash it like a zip with TWRP.

Enable signature spoofing. Do this by installing the magisk modules "riru" and "riru - LSPosed". When the latter is installed and yourv system restarted, you should have a LSPosed app. If you run it it will give you the option of hiding the app and in the settings you can create a shortcut. Once this is done, then install the LSPosed plugin "fakegapps" (version 2). You should now have signature spoofing.

Install the magisk module for microgG (microG Installer Revived)

Once this is all done, run microG and run its self check.

Remember, by default microG still talks to Google. It tries to limit the damage, but I suggest familiarising yourself with it. Also some of the location modules that are available for it are somewhat privacy invasive (OSM, for example, logs your IP and location with every address query if you use the Nominatim back end). I like that I can set it up to disable push notifications (which of course go through Google servers) and/or make it ask for permission every time an app tries to register.

You can use the Aurora store and get access to paid apps too. You can pick your level of engagement with Google.

Some other suggestions if you don't already:

Use app manager from f-droid to block any trackers it finds on G-store apps you use. Do this every time you install an app. Some very few apps don't work with all their trackers blocked, but most do.

Bromite is a good degoogled browser

Magc Earth is a good real-time replacement for Googke Maps, though it's admittedly not as comprehensive.

For a great offline map/navigation app (uses pre-downloaded maps) I highly recommend osmand (f-droid). You never have to worry about lifting cell signal again, you'll always keep navigating.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kudalufi:
Yes. Go to Settings-->PHH Treble Settings-> Samsung Settings and enable it there. I verified it works. I will note, I am now using the May 10 GSI, so if you're not then YMMV.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] sumur:
Awesome thank you
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I used the updater to update to the latest version and lost magisk. I thought that just meant I had to reinstall it but that hasn't worked. Is there a way to get it back or do I have to use TWRP to restore the earlier version?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Hausemaster:
I had to flash the patched stock rom tar from Odin to get it working again, so, basically I had to start from scratch
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kudalufi:
I was able to update (to the May 10th build) by flashing a new GSI with dd from Andy Yan's builds page (as per the instructions at the bottom of the OP). This only overwrite's system. I then used TWRP to erase cache & dalvik.

Magisk (the app) was still installed, as well as the LSPosed shortcut, but the magisk SU was gone, of course, as were all root filesystem tweaks. I had to redo the brightness patch, reflash magisk through TWRP, and then redo all the magisk modules and microG, but at least it's not a total redo from scratch.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kudalufi:
BTW, slightly off topic, but maybe useful since everyone here has the same tablet. I found a great keyboard/mouse/case for this device on AliExpress. It's only $40CAD. It's great for SSH (connectbot), termux, VNC connections (avnc), and for emulated DOS and Amiga games. Shipping takes a while from China, but it's worth it.

Using SD Card as Adaptive storage do not work.

It send error: Attempt to invoke virtual method 'java.lang.Stringandroid.os.storage.VolumeInfo.getId()' on null object reference.

Already tried to change SeLinux to permissive but do not work either.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Using an sd card for Adoptable storage will degrade the tablet performance drastically. SD cards are very slow compared to internal storage, so current ROMs don't allow it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] 564:
I know that, i was a rom cooker for xiaomi mi A3 but at least if there is that option it should be allowed to use that.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I only know that it is no longer allowed. It isn't up to me what should or shouldn't be.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kudalufi:
This is simply (and demonstrably) untrue. Almost every tablet, including this one, uses sdcard hardware for its internal storage. A good, fast external sdcard will have little to no performance penalty compared to internal. Testing with pv shows a sustained write speed of about 85MB/s on the internal which is well within the realm of a good card.

This is news to me. Can you provide a reference?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
Sorry, but I don't have to prove anything. If you don't choose to believe me, that's your choice.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
As I said, I don't have to prove anything, but for your own edification you might want to use the "SD Card Test" app to compare the speeds yourself.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Kudalufi:
You must have got the information that current ROMs don"t allow it from somewhere. I can find no reference to suggest adoptable storage is a feature Android is deprecating. It would be helpful to know what the source for this is.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I can't help it if you can't find it. The lack of adoptable storage has been discussed many, many times in XDA. I'm not going to do your searching for you.

Really wish didn't keep losing the ability to change brightness after each update (and can't reapply the script without formatting the data).
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wizzdome:
Just curious... I do not have latest stock installed but I have Rooted stock with magisk. build (T500XXU3BVA4) Is it possible to just install TWRP and skip the rest. It is honestly easier for me to get into recovery from terminal with su access (su and reboot recovery) But I don't wanna mess anything up so curious if not having latest FW would affect installation as well as having magisk on at time of install.

EDIT...

Tried anyway... installed fine but no wifi... trying from scratch with latest stock...

Edit 2...

I tried from latest stock with op image and still got no wifi. Then I started skimming through the responses in this post till I got to page 9. Where someone posted what they did to install and get wifi using a GSI instead of op image. Since I was not doing this in linux I followed op install instructions for updating Lineage with a GSI and All went fine. I still havent put in the brightness fix, but honestly for me the brightness is fine at the default. ( i will probably do it later) Then I had to battle with GAPPS... Having no GAPPS with GSI i went and download a Nik GAPPS and booted into recover with adb... However I could not find the dang file I had just downloaded as it was not in downloads folder on either the system sd or external. (I am still fighting with this) So I downloaded it to my pc and planned to put in on the sd. That was when I learned that the usb file transfer is not working. ((SIGH)) I am transfering it via bluetooth now. Hoping I can figure out how to move it to the sd card as in the file manager that is on here did not seem to have the option to copy and paste. I probably would have just been better off removing the card and putting in the pc. Fingers crossed. But atleast Wifi works and bluetooth works... If anyone can tell me of a fix for usb file transfer that would be nice. ( i went into developer settings and changed usb config to file transfer and that did not help at all) <({[Thanks to the Op]})> and I plan to give a thanks to the poster who gave me the fix for the wifi in his post...

EDIT 3... OMG

Got the gapps onto sdcard (there was a copy to in the files app) however install failed (used nik go) now I need to figure out which gapps to use since open gapps doesnt have 12. This install has taken me all day and has been nothing if not frustrating. I am determined tho.

I would like to add something about the TWRP reboot loop. I get this about every time I use it. I go to the terminal in twrp and type "exit_twrp" and I get this error that says there is no room to write or something like that... and it still keeps rebooting into recovery, however I found that if while in terminal I type "reboot system" it will finally boot to the system without the reboot. Thats a bit frustrating to have to do every time but hey they price to pay to have such a nice recovery system. anyhow hope that helps someone and maybe op will want to adopt that for the twrp reboot problem...

thank you, that kernel fixed the usb issue no i am having problem either finding the right gapps or i am not installing right I have tried a few different versions the closest I came was bit gapps but it still errored out on me saying unable to mount system rw you wouldnt happen to know how I can get gapps on here do you?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Hausemaster:
To flash gapps you have to use a vndklite variant of your gsi
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Jim in CA:
When I did the initial install, the ROM from the original post included Gapps, so I didn't install anything else. When I updated using the Updater from the Settings, I found I no longer had Gapps. I installed MindtheGapps for Android 12 using TWRP, and got them back. And I needed to install the kernel fix again too. But I lost the brightness fix, and have not gotten that back yet. I have refrained from formatting the data as suggested by kbeezie.

I would suggest going with Hausemaster's suggestion, not the Updater program.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wizzdome:
thanks I am gonna flash the lite version and try the gapps after... glad you guys keyed in when you did I was about to start over from scratch lol

Edit...

Tried that and same results... So I started from scratch... Instead of latest firmware I used the one listed in the op and installed the image from the op... no idea why wifi works this time but it does... atleast I dont have to fuss about installing gapps anymore... I appreciate your help though.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wizzdome:
Okay after some playing around on the Rom I am in agreement that the memory management is lacking. I have experienced quite a few system freezes while playing games. I like the look of the rom but its not quite what it needs to be to become a daily. I had the worst experience with trying to get GSI to let me install gapps and feel like a day was wasted in the process. I hope this rom becomes more stable with more detailed instructions of how to get everything working. (not that the op didnt give enough) I felt there could be a bit more. I appreciate the opportunity to test the rom, so thank you for that. The stock android 12 comes out the 22nd of this month so I guess I will just wait till then and see how the stock runs. Good luck and thanks to all who have ran support in here.

Hi is there any roms easy to install on samsung Tab A7 sm-t500 no Hassell. When I look the forum it seem lot of people struggling to install lineage. So does this tablet have other customs roms to install or we only have the lineage only. For those whose install lineage is it worth it. My biggest problem why i want to have more space on my 32gb storage but only remain 12 gb and didn't put to much apps. That the only reason I want to install a customs roms to have more space.

Thanks in advanced

I'm wondering if the update method at the end of the OP can be used to flash a different GSI, e.g. Pixel, without losing data or is a clean install the only way?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wizzdome:
Its always better to clean install, unless you are just flashing an updated version of the same rom...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
I'd say a clean install is always safer, but not necessarily better. If a dirty flash works, and I don't have to re-install everything, I find that the better choice.

according to these guys official android 12 is now available for the SM-T500

Flash from Odin is recommended
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lewmur:
You can always run Odin on a Linux box using a Windows session on VirtualBox. You don't even need a to activate Windows to do it. Just use MS's Media Creation tool to get a Windows 10 or 11 iso and boot it in a Vbox session. I find that easier than using Heimdall.

Hi,

I followed all the steps to install lineage os 19.1 on my Tab A7 SM-T500 (Wifi only version). After installing OS, Wifi and Bluetooth is not working. I followed the steps again 3-4 times to make sure I was not missing something but every time WIFI and Bluetooth did not work.

Any Idea how to get wifi and Bluetooth working on lineage os 19.1.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] jmanzoson:
Just popping in to say thanks for the line-by-line instructions! This fixed my wifi not working. If I had to guess, I would say using the .img file in this line instead of the one in OP is what fixed it:
