[Samsung Galaxy Tab A series ROMs, Kernels, Recover] zpunout:
17.1 (Android 10) uses legacy based storage access framework which is noticeably faster for certain tasks compared to newer versions of Android. I haven't tested the speed differences specifically on this Samsung tablet (T357), but have tested it on the Sony Xperia XZ1 and XZ2 Compact phones with noticeable speed differences in some older apps. Modern apps didn't seem to have any speed difference.

Just wanted to share here that from my messing around with postmarket os I found out that android on this device is running in armv7 compatibility mode. the a53 chipset is actually armv8 and postmarket uses it as such. I don't know if there is a way to get android to run in 64 bit mode because of all the proprietary 32 bit drivers, but I thought I'd share.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
While my previous answer in the post below was wrt to a newer version of the kernel, the same thinking applies to making any roms, past, present or future to 64 bits applies for the entire msm8916 platforms that I build.

https://xdaforums.com/t/how-to-build-linux-4-4-x-for-galaxy-msm8916-devices.4523411/#post-87781117

I also have a SM-T813 (msm8976 64 bit rom) and SM-T810 (exynos5433 32 bit rom) and both are 2nd generation S2 tablet devices. I can't tell any tangible differences in performance between the two. Both are 3GB DRAM devices. I made 18.1, 19.1 and 20 roms for both.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ~7~:
Okay I'm super frustrated and I feel like all of the work that I did to get the tablet to work just disintegrated after the lineage recovery overwrote the TWRP

Because now I can't boot into lineage

The tablet just won't boot into the OS

I'm either stuck at the bootloader

Which it's telling me that I've waited my warranty and I'm in Odin mode and all of that stuff in the different colored mono space text

And then I can boot into recovery mode

But then it's the lineage recovery bootloader the purple thing

And it doesn't matter what I try to do

I can't get back into the operating system no matter what I do

And it's really frustrating because I was able to finally get into lineage

After updating TWRP to the correct version number

And then I was able to flash into the correct lineage

I was just having trouble with the GAPPS so I tried to go back into the bootloader so I could flash the gaps but they didn't work

And not only did it not work but the lineage recovery over wrote TWRP and so now I'm stuck and I can't boot the operating system

So I don't know how to prevent TWRP from being overwritten by the lineage bootloader recovery

I'm really frustrated

Because all the files are still on the SD card

I just can't select any of them to install TWRP

And I don't know how to prevent TWRP from being overwritten
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lpedia:
Unless you've managed to damage the system partition, simply replacing TWRP with Lineage recovery shouldn't prevent the device from booting the system. From Lineage recovery, "Reboot system now" should work. So should powering the device off and turning it back on again.

Get TWRP back

You shouldn't need to access the SD card in order to restore TWRP. Re-do whatever you did to install TWRP in the first place. You probably used Odin or Heimdall?

If the system isn't booting -

Boot to TWRP and clean flash LineageOS and the gapps package (you must flash gapps before the first system boot).

Stop Lineage recovery from overwriting TWRP again

When you boot the system the first time after the clean flash, Lineage Setup should run automatically.

Go through it carefully: look for a tickbox that says something like "Update recovery with Lineage". If this is ticked, Lineage recovery will replace TWRP whenever there's an update (dirty flash or OTA update). Make sure it's unticked.

[Edit] @retiredtab assures me this ROM is configured with that box unticked and disabled, so it shouldn't have been possible to turn it on and make LineageOS install Lineage recovery by itself.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lpedia:
@~7~ - because that tickbox isn't enabled, I don't understand how Lineage recovery could have got installed. Can you explain exactly what you did?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ~7~:
Unfortunately every time I try to reboot the system

It just brings me back to the lineage recovery

If I select anything else brings me back to the normal boot

But that just tells me that I voided my warranty and it just sits on that screen forever

Unfortunately this was a tablet that was given to me after somebody was locked out of it after traveling to Australia

All is she wanted was her pictures off of it

So I was able to root it get TWRP on it and get her pictures off of it

But this was years and years ago and I had a very old version of TWRP on it

So I was able to update the version of TWRP on it using TWRP

But I originally had access to a Windows computer and using Odin on that was super easy

But I completely switched to Linux but I've never been able to figure out how to get Heimdall to work properly

I couldn't figure out which g apps package to work

I'm open for any and all suggestions of gApps packages that you thinks works the best

I've just had difficulty finding any that would flash properly

Yeah I saw it mentioned something about that but I didn't see a checkbox that I could check or uncheck so I just thought it was going to do it regardless

I don't know exactly what to say all as I know is it has lineage recovery on it and I don't want it to be there because I can't even get into the operating system now

I just need some step-by-step help to get the tablet back working cuz it was working I just don't know why it stopped working

Just really frustrated
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ~7~:
Listen I don't even understand what I did wrong either

That's why I'm posting on here because I've run out of options and I can't figure out how to fix it by myself

That's literally the only reason why I'm asking for help cuz I'm super embarrassed I don't know what's wrong I don't know what I did wrong and I'm super embarrassed that I have to ask for help to begin with

I just want TWRP back

But I'm using Linux now and I never figured out how to get heimdell to work properly

I'm using Garuda dragonized gaming edition which is just a fork of arch with extra sauce built-in to make it a little bit easier to use?

I'm downloading it as an AUR hopefully it installs properly

I selected a branch from a git repository That claims that it's an actively maintained branch or fork of Heimdall but we'll see

It's specifically called Heimdall-Grimler-Git

It claims that it's an actively maintained fork of Samsung phone firmware flashing tool in the chaotic AUR repository

It's version number is two decimal 0 decimal 2 decimal r02 b577 e-2.1

I'll post an update after it's done installing and after I figured out how to use the software to see if it can actually work
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lpedia:
Let's see if you can install TWRP using heimdall. I assume you have already downloaded the TWRP via the link in Q5 of post #2 (if not, download it now - you want the IMG version).

First, put the T350 in Download mode, then connect the PC to the T350 and run a command like this:

heimdall flash --RECOVERY twrp.img --no-reboot

where heimdall is the command to run your version of Heimdall and twrp.img is the full filename of the TWRP .img file.

Don't forget the --no-reboot option! Otherwise it'll automatically reboot the device after flashing the image, and the previous recovery will overwrite the TWRP you just uploaded.

To make the new recovery permanent, you have to get the device into recovery mode once before letting it reboot to any other mode.

To go to recovery mode from Download mode:

Hold Volume Down + Power until the screen goes blank.

Immediately hold Volume Up + Home + Power until it boots into TWRP.

If you weren't quick enough with the second key sequence, TWRP will be overwritten. You'll have to start again.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ~7~:
Yep I have the files that are listed from link Q5 of post number two

Thank you so very much for providing the specific terminal command that I needed to input

I had no idea that I needed to specify the no reboot option

So this is very helpful

Thank you so very much for providing these specific instructions these are crucial for me to understand the particular steps that I needed to follow in sequence

So we've got some good news and some bad news

The good news is the commands that you told me to put in worked albeit temporarily

After I input the command and did the Konami code with the buttons

I was able to boot into the operating system finally

Unfortunately when I rebooted

I'm back at square One at the lineage recovery

I'm not exactly certain why I thought the TWRP recovered it

But for some reason it didn't so I'm back at square one

I had to connect back to the computer and run the heimdoll command again

I'm not exactly certain how to prevent it from overwriting TWRP with the lineage recovery

I have installed this ROM recently and it runs pretty well considering the device's age. I installed BiTGApps core with it and I've had no issues with it but, I have noticed that the AAC audio codec in local video playback does not work. Did I do something wrong or is this a known issue?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
What app are you using to do video playback and what is the source material that you are trying to watch/listen to?

I have no problems watching videos using Newpipe.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Luke357:
Every single video file I try gives this issue. I've tried the default video player, VLC, and File Manager+. All give the same error. YouTube in the official app works fine and so does every website I've tried.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
I have none of those problems. I suggest you try the following as it's been reported that some gapps projects cause potential media playback issues.

1. Backup all your data.

2. Boot into TWRP and wipe everything and FORMAT DATA (answer yes).

3. Install JUST the rom and nothing else (no gapps, no magisk, etc).

4. Boot into OS and do just the minimal setup.

5. Try playing video + audio. If you need an app, use Aurora Store https://auroraoss.com/AuroraStore/Release/AuroraStore-4.4.2.apk or

https://f-droid.org/ .

6. If the above works, then you need to find an alternative gapps project. As I stated post #1, I have NO KNOWLEDGE for the current state of gapps projects as I do NOT use it. It's the user's responsibility to do research on which one works for his/her own needs.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Luke357:
Reinstalled without BitGApps Core and it worked perfectly. A standard format would cause bootloops but wiping everything except bootloader/recovery did fix the issue. I'm honestly surprised that Gapps would affect audio in video but it did. Thanks for the help.
