BACKUP YOUR DATA AND OLD rom BEFORE trying my rom.

If you are NOT an expert in using fastboot, adb, odin, heimdall, twrp, DO NOT use this rom. You must know how to use these tools to revert back to your old rom.

If you are new to flashing custom roms, do NOT attempt this.

Got it installed on a T357T. Booted up and configured. However, WiFi has same problem as stock rom: will not connect even though it sees all the SSIDs and the WPA2 info is correct.. I think this one may have a wireless card issue. Good work, BTW!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
If wifi doesn't work on stock rom, then it's unlikely to work on LineageOS 18.1. I agree that you may have a damaged wifi card.

You may want and try to setup a wifi ssid network where there is no encryption just as a test to see if that will connect.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] js290:
I did when it was on the stock rom, but it still did not connect. You don't happen to know the wireless card part for SM-T350 series tablets?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
Hmm, strange that you can see the ssids, but not connect even without encryption. Do you have another router to try?

Ifixit says this is the replacement wifi

https://www.ifixit.com/Store/Android/Samsung-Galaxy-Tab-A-8-0-Wi-Fi-Motherboard/IF322-030?o=1

You might want to make sure all the cable connections are secure and that the wifi antenna cables haven't come off their connector especially the transmit. It's a bit hard to see their picture clearly, but I think the wifi antennas might be at the bottom right hand corner?

PS. If you are running 3rd party firmware on your router like openwrt, there may be logs that you can enable to see if the SM-T357T is actually transmitting wifi packets. For example, I'm running openwrt on my router so I can see it's system logs for wifi. I replaced some hex values with ab:cd:ef to preserve my MAC address privacy.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
Is 192.168.1.2 the address of your router or the SM-T357T?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] js290:
That's the DD-WRT router which sits behind the CM router.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
Well, if wifi didn't work on stock rom without encryption, then it's likely a hardware wifi problem on your SM-T357T.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] js290:
Yeah... or maybe the wifi adapter firmware. I'm gonna try flashing stock ROM again and see. Thanks again and for the good work with LineageOS build!

Q24. Will this run on the SM-T355 or SM-P355?

A24. No. It has not been tested on the SM-T355 or SM-P355 and it's likely the touchscreen won't work.

Confirmed booting on an SM-T355Y. Touchscreen works

To install, I had to modify the updater-script file in path /META-INF/com/google/android/ to allow it to install unconditionally
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
If you can verify the functionality in "what works" as per post #1, I think I can modify the script to add the SM-T355.

The reason I wrote touchscreen likely won't work is that the SM-T350 and SM-T357W require different touch screen drivers. Since I don't have a SM-T355, I guessed that it would likely require it's own touchscreen driver as well.

Also, please test the selfie camera/video using stock camera and simple camera. It may actually work, but I didn't know that my selfie camera has a hardware problem since I bought this used so I can't test it. Simple camera 5.3.1 can be downloaded from

https://f-droid.org/repo/com.simplemobiletools.camera_77.apk
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] zpunout:
This is what I've discovered so far:

What works on the SM-T355Y

1. bluetooth

2. wifi

3. automatic brightness

5. GPS

6. audio through headphone jack

7. audio over bluetooth

8. Camera and selfie camera (selfie camera won't take pictures with the snap app but will with Simple Camera).

9. Video recording (no audio)

What doesn't work

Microphone

Untested:

LTE connectivity

Thanks for building this ROM for the Galaxy Tab A
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
I think I might be able to fix the selfie camera using stock snap camera app in the next build by following these 2 commits I made for the SM-T350 dated May 7, 2022

https://github.com/retiredtab/device_samsung_gt58wifi/commits/lineage-18.1

The microphone works on my T357W. I used the LineageOS built in recorder app and I can record and hear my own voice.

Hi, I'm planning to try this build on an SM-P355 - the difference being virtually nothing but having an S-Pen between the T355, wondering if that will cause any issues? And is the build at a place where it can be safely used? Thanks a lot.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
No one has tried this on a SM-P355. I can only tell you that the SM-T550 and SM-P550 (big brother to SM-P350) have inverted x-axis on the touchscreen.

That is, if I take the SM-T550 rom and load it on the SM-P550, the x-axis touchscreen is inverted. That might be the same case for the SM-T355 code on the SM-P355?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
BTW, if you do try this, don't be surprised if the TWRP gives you an error when trying to flash the zip.

I suspect your SM-P355 might have a code name like gt5note8wifi which is NOT part of the OTA assert in this commit

https://github.com/retiredtab/andro...mmit/1070b76a4a10886ea243e14469af6337f0c1e17d

You can always remove the assert from the updater-script in the zip. Again, this hasn't been tested so you assume all the risk. Backup your data and know how to go back to your old working rom before you try this.

but actually

i have used another person's lineageos 18.1 rom which also built for t355(i flashed t355's twrp into p355)

it runs good on p355,the touchscreen works ok,no inverted x-axis

the built in camera app will crash when i using the front camera

except these problem

it works great
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
The above might be because I'm using the T357W media_profiles.xml as per

https://github.com/retiredtab/andro...mmit/b311a4d7acb733d7b7efc2be70c0b7f4109eb7c6

and it might not work for 355 variant camera. You can always try to get stock 355 media_profiles.xml and replace it.

My T357W camera is broken so I can't test any of it.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] zg7681:
will u build a lineageos19 for t355?

maybe i can graft the rom on p355

I didn't include the above in this FAQ because this is the first time I've heard about it on the T355Y.

You need to find a stock Android 6.x T355Y build for your device. Then flash that stock Android 6.x and then install my TWRP. You may have to try multiple versions of stock 6.x before you find one that works.
