I installed the sm-t500 pixel experience, but it keeps rebooting due to crashes. How do I execute the watchdog command? Please answer in Korean or English.
[Samsung Galaxy Tab A series Guides, News, & Discus] joyeonu:
I installed the pixel experience on the sm-500, installed magisk delta canary and tried to install directly to the system partition, but it says that it needs to be mounted by journal-picking. So how do I proceed with mounting the system partition (read-write)
[Samsung Galaxy Tab A series Guides, News, & Discus] Niki3797:
I was facing the exact same problem on my tab A7 (SM-T505) when installing Pixel Experience Plus 13.0

These are the things that I did to install Pixel Experience Plus 13.0 on my tab without getting stuck in the setup

1. Format the tab from TWRP

2. Install Pixel Experience Plus 12.1

3. Flash Magisk zip and reboot back to TWRP

4. Flash watchdog fix from TWRP

5. Reboot to system and complete the setup (The Face unlock works on Pixel Experience Pus 12.1)

6. After completing setup reboot to TWRP and Dirty flash Pixel Experience Plus 13.0

Note: I have used the vndklite version of the GSI

GSI:

1. Pixel Experience Plus 12.1 : https://github.com/ponces/treble_build_pe/releases/tag/v416-plus

2. Pixel Experience Plus 13.0 : https://github.com/ponces/treble_build_pe/releases
[Samsung Galaxy Tab A series Guides, News, & Discus] talksickisil:
Side note here. I have had success (so far, at least) with gsi that are 3.4 gb and larger by tweaking the fastboot resize command to: fastboot resize-logical-partition system 3990000000 instead of 3940000000. I just tried this the other day and have only flashed project elixir (which I didn't care for) and alphadroid gsi. Both wouldn't flash until I tweaked that value.
[Samsung Galaxy Tab A series Guides, News, & Discus] DJ_BARO:
Good Day!,

thank you very much for that updated instructions it worked like that flawlessly for Pixel Expierence Plus build from May!

I was even surprised that even rotation on lockscreen works now!

But i had one big issue which caused me to go back to stock rom. Its Bluetooth Audio.

It will allow me to connect my headphones with the tablet but the sound will still be coming from the tablet even though i selected output through the headphones on the volume tab.

Do you or anyone else also expierence that issue? Does anyone know how to solve the issue? That was for me an deal breaker.

Also i noticed that the task bar doesnt change the color in light mode it stays dark. Thats minor though.

Many thanks for any help! :)

Got an SM-T500 with the latest firmware. Not matter what it end up with "only official released binaries are allowed to be flashed" when trying to Magisk Canary and setup it breaks and locks up

Twrp flash ends up same way.

Downgrade it not an option (not allowed)
[Samsung Galaxy Tab A series Guides, News, & Discus] linuxlonestar:
I did all the way to the end with no problems, until I wanted to change the gsi I was using. I reflashed the stock firmware, re patched it, and flashed it. come to step seven, and it boots into a blue screen that says unathorized binaries can't be booted. How do I fix this? the bootloader is unlocked.
[Samsung Galaxy Tab A series Guides, News, & Discus] bunny0007:
Have same issue, guess Samsung do not want to allow any custom kernel or recoveries anymore, even if the bootloader are unlocked.
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
hope someone finds a way to fix this for new versions of android
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
not sure about headphones, its a gsi, it works on some devices but not others
[Samsung Galaxy Tab A series Guides, News, & Discus] Niki3797:
Go to Developer options and

Enable "Disable Bluetooth A2DP hardware offload"
[Samsung Galaxy Tab A series Guides, News, & Discus] Jim in CA:
I have done two SM-T500's using this procedure, and it worked. I downloaded the stock firmware using the Frija tool found on the XDA website. I used the 3.14.4 version of Odin. Someone on another thread for this device had a similar issue. He was using 3.14.1. He got the newer version of Odin and used a different firmware, and it worked. Give it a shot. At this point, not much to lose. I used the T500XXU4CWA1 firmware from Frija as my starting point, patched as described.

I used Andy Yan's Lineage 19 GSI. I am happy with it.
[Samsung Galaxy Tab A series Guides, News, & Discus] bunny0007:
Thanks seems to work

But cannot get apps2sd to work, it only a 32gb so it is almost full at start
[Samsung Galaxy Tab A series Guides, News, & Discus] Jim in CA:
I originally used a Andy Yan GSI file from October of last year, and I had issues with not having access to the SD card. (I had the same issue with two other tablet models using that same GSI.) But I was able to access it when in TWRP. Using the newest lineage-19.1-20230508-UNOFFICIAL-arm64_bgN-vndklite.img file fixed the issue, at least for me.

My tablets are from Costco, and are the 64gb version, plus came with a 64gb SD card.
[Samsung Galaxy Tab A series Guides, News, & Discus] bunny0007:
Thanks it seems to work with lineage-19.1 :)

Do i still need to use Brightness Fix and do i run the sh file from twrp?
[Samsung Galaxy Tab A series Guides, News, & Discus] Jim in CA:
No! Load the SM-T505-brightness-watchdog-fix.zip file from the first post of this thread as a module in Magisk. That will fix the brightness slider.
[Samsung Galaxy Tab A series Guides, News, & Discus] bunny0007:
Ok

Used it from this https://xdaforums.com/t/rom-sm-t500...4-2020-lineageos-19-1-and-twrp-3-6-1.4421365/ and working :)

@Hausemaster it seems like you know a lot about the Samsung's watchdog issue on GSi and the autorebooting issue. i've been having the same issue on My Samsung Tab A8 LTE (SM-X205). The Device just boots up and then reboots automatically after around 4 to 5 minutes of uptime. This only happens on Android 13 GSi's and not on Android 12 or 12.1 GSi's. And i know its watchdog that's causing the auto rebooting. i also tried your watchdog fix module but it doesn't work and also there is nothing in /dev/watchdog. it would be great if you could give some information about the research you've done on this.

if possible can we communicate on Telegram? My telegram username is https://t.me/SamDaaEpic or we can also talk on discord, my username on discord is "samdaaepic".

if not possible its ok to talk on xda, i just prefer those because of the time it takes on xda.

phhusson is working on implementing a ims from scratch on https://github.com/phhusson/ims .

[Samsung Galaxy Tab A series Guides, News, & Discus] SamDaaEpic:
Yeah, it's being worked upon. They are currently working on making the SMS stable enough and probably in the future VoLTE might get supported (I asked him, he does have plans to support VoLTE). Currently only Phhusson and Martinetd are working on that IMS.
[Samsung Galaxy Tab A series Guides, News, & Discus] SamDaaEpic:
Did your Tab A7 also didn't have the '/dev/watchdog' entry? Or it had it and you just put a V in that file to disable watchdog' at boot?
[Samsung Galaxy Tab A series Guides, News, & Discus] SamDaaEpic:
Can you please link the GitHub issue he documented the issue on? I can't seem to find it.

Hello there,

After Magisk rebooting the tablet (t500) didnt boot so I reflashed the stock firmware. I thought it didnt do the Magisk because the bootloader was locked. But after the stock firmware flash it gave me a warning saying that the bootloader was unlocked.

I am confused. What could have caused this?

Edit: After the patched flash, I rebooted after connecting to the internet and cheking the oem unlock. It worked.

The directions in the OP are from 2 yrs ago. You more than likely have Android 12 stock ROM and I think you can't downgrade to an Android 11 ROM. Look for a thread to install 12 or 13.
