[Samsung Galaxy Tab A series Guides, News, & Discus] drsanusi:
For me i take vbmeta and recovery flashing through odin .work nice. As of rom i tried

Lineage19.1 1052022 works very nice .and smooth ....with ph root app

Others

Xtended 12.1 from nippon ports ...not working stock at logo boot .( i read some notice some where ??they dont support enforcing linux .so they dont boot ??)

Corvous rom 2.1 stuck also on boot logo

Can we share our experiences which rom boot nice ? And how ?

Thank u ......was great instruction @Hausemaster
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Hey, @drsanusi ,

I've only tried ProtonAOSP, Lineage OS, and crDroid and they booted just fine with the standard steps...

And I've found a few things that can be worked around, and I added them in the OP... So, if you have any workarounds or any roms that work, do let me know, I'll add it in the OP...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Hey everyone, I'm going to stop updating this post from now on, as I'm going back to stock soon...

Add once this device gets its last update, I'll come back to the modding scene again!

It was a wild ride, and I learnt a lot on the way, but, it's time I bid my farewell, goodbye for now!
[Samsung Galaxy Tab A series Guides, News, & Discus] drsanusi:
Here with great news. I found fix for brightness. Control.

Now on proton aosp gsi .after flashing kernel..just flash (( permissivier v5.)) And then format system . all working fine .

I think well works on all ROM's that boot

Tested on proton aosp
[Samsung Galaxy Tab A series Guides, News, & Discus] mrspeccy:
Thank you for the guide. I am running AndyYan's LineageOS 19.1 on my SM-T505. The fixes for the non-working brightness slider proposed in several threads here on XDA did not work for me (maybe it is Android 12, maybe the securize option; it seems that phh-on-boot.sh is not really used, although my partition is RW and the file is patched successfully).

I therefore made a Magisk module that issues the "echo 100 > ..." command mentioned in the OP after every boot. See attached. Just flash as a Magisk module.
[Samsung Galaxy Tab A series Guides, News, & Discus] GyuminLeo:
tried this way but the device doesn't boot

boots back to twrp
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I'm no longer maintaining this thread and can't test anything, this worked fine on A11 stock, idk about a12
[Samsung Galaxy Tab A series Guides, News, & Discus] GyuminLeo:
I was using A12 and installed the version you said A11 2022 January patch but the kernal patch still says A12
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Gsis don't boot upon starting from one ui 4.1 as after flashing the kernel zip, the device entered a bootloop, but the instructions in the op on starting from Jan 2022 A11 rom do work as of now...
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
how can i flash the los 19.1 vbmeta?

i dont want a ded tablet
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I patched the AP file with magisk so that flashing vbmeta was not necessary, as i never understood how to do it, so, as long as you patch AP using magisk, you won't need a vbmeta and you won't brick your tablet...
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
i ment with lineageos 19.1 on another forum, it was userdata
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
That is fine if all you want to do is root the stock ROM. But if you want to install anything custom, either recovery or ROM, the you must first flash vbmeta, factory reset, boot, connect wifi, skip the rest of setup, re-enable Dev mode. To flash it, just put it in the AP slot in Odin.
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
It worked on AP for me, if I put it in userdata, it complained about custom things and refused to boot

Edit: I used the stock AP to test vbmeta flashing, so, it should work for everyone...
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
some others saythat i should flash it in userdata
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Actually, do not change the partitioning to full A/B, it's unnecessary, the point of super partition is that partitioning is done dynamically and it takes up relatively less storage, here, rather than having two copies of partitions, it only has one and there's a low chance of someone screwing up their device, and either way, Samsung always uses this type of partitioning even in their flagship devices, so, a good vendor is the only thing we need for GSIs to run properly...

Edit: A/B is helpful if we want seamless updates, for the how to make a vendor part, i think your best bet is to look for a similar device that has a GSI vendor and then look at what they changed and try replicating it on this device with appropriate changes...
[Samsung Galaxy Tab A series Guides, News, & Discus] ismail demirbaş:
Do you know the device model with processors close to each other except Samsung, it would be enough if it was close, but if it was the same, it would be ported very well.

I think there is no information about vendor porting, will it work if we try to install it without porting?

Do you have some information about vendor porting or the site you know?
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Happy new year everyone!

I have reported some of the bugs ive been having on pph treble pixel experience on tab a7 t500

32gb storage

Here is the list:

1: format as internal for apps to sd card not working with error shown in picture 1

2: lockscreen only works on portraid which is annoying cus i have autorotate off and i need to enable it and disable it again to rotate

3: brightness only works for 60% then doesnt do anything after that the lowest the brightness actualy goes is in pic 3 even with the magisk module.

I havent yet found any workarrounds but here is the list
[Samsung Galaxy Tab A series Guides, News, & Discus] miguelgoescrazy:
I am having the exact same problem as of right now, it shows I have 64Gb of storage but won't let me install apps? Is this the case with other GSIs?

I am using Pixel Experience 11 GSI as I do not like the new 12.1 L taskbar
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
I already have Android 12 CVG4 patched and rooted with Magisk. I want to try Android 13. Can I just proceed from step 9 in the instructions?
[Samsung Galaxy Tab A series Guides, News, & Discus] miguelgoescrazy:
Is anyone having a problem with the System UI crashing every now and then, its been happening with all the custom roms I've tried

People say to downgrade magisk but I am unsure if that is the cause
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Yes you can do so...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I've not had any such issues, maybe swap isn't provisioned for you, check it using smart pack kernel manager, and allocate 2GB if not already allotted
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
1. Hi, afaik, format sd as internal was deprecated in Android(not entirely sure)

2. That's an annoying bug, I usually leave autorotate enabled, no workarouns soo far...

3. The module only does the work of making brightness adjustment possible, I think the brightness scaling is being incorrectly calculated by the gsis...
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
Thanks, I already did it. The only problem I had was trying to use Magisk to flash the fix and brigtness. Wound up flashing the zip with TWRP.
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
@ismail demirbaş I don't have much idea on vendor porting myself, but one GSI i think you may like is the NokiaUI GSI from Nippon, it boots properly, is stable, and most of the things work OOB without any workarounds being used, and, battery usage stats also work....
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Oh... I wish we could somehow make a script that won't depend on magisk, but is directly put into the system partition and is executed on boot automatically, that would save a lot of trouble with the watchdog reboots
[Samsung Galaxy Tab A series Guides, News, & Discus] miguelgoescrazy:
I did however allocate 2gb and enabled a low memory at a very light profile and I'll see how it runs, I am most likely going to go back to my stock and start fresh to try other GSIs, so far I tried crDroid and Havoc OS and those wouldn't boot up so I'll give an update
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
As per my experience, the pixel experience GSI always boots, so, give it a try if you would like to...
[Samsung Galaxy Tab A series Guides, News, & Discus] miguelgoescrazy:
Ok, I will update you, but I got pixel experience android 13 at the moment and it runs really well with the fixes and better than stock debloated. I am using the android 11 BUJ1 Firmware since I don't want to upgrade to bootloader 4 since I cannot downgrade back and alot of GSIs have been breaking with wifi I heard.
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
I've got the Pixel Experience Android 13 ROM working but I don't like the Google Assistant search or the predictive apps at the bottom of the home screen and can't find a way to remove them. Anybody know how???
[Samsung Galaxy Tab A series Guides, News, & Discus] miguelgoescrazy:
I hate those apps and I just use a magisk module to hide it (look up Taskbar hider android 12.L) and currently I'm planning on downgrading android versions so.
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Oh i have a new update atleast my smt500 is passing SafetyNet and two API levels with just safetynet and SafetyNet mod if anyone wanted to try and if it's works for others could add that To the guide
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
I d/l magisk-pe-taskbar-fix-hide.zip and ran it but it didn't do anything.

Hello!

i succefully mod my samsung tablet sm-t505 with the pixel PE 13.

I succefully installed the viper4android mod to enable stereo speaker (only left audio channel on all the 4 speaker) but i have some problems with the flip cover (the hal sensors is not working?) and with the taskbar that is not displayed correctly. I already installed the magisk module "hide-tablet-taskbar" but the taskbar is still buggy.

Any suggestion to fix this problems?

Thx in advance

[Samsung Galaxy Tab A series Guides, News, & Discus] ismail demirbaş:
Did you unlock the bootloader and did you install it with the internet when the device was turned on?
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
i just connected to the wifi after the setup after unlocked bootloader, but when i was able to barely run pixel experience, it was on 8gb storage and the ui kept on crashing and magisk wouldnt work
[Samsung Galaxy Tab A series Guides, News, & Discus] wEER1234:
first you have to flash official one without magisk then patch it to magisk and then install that rom
[Samsung Galaxy Tab A series Guides, News, & Discus] ismail demirbaş:
8gb memory shouldn't drop that much, isn't your device 32gb memory?

Magisk delta use it you won't have a problem stuck on the boot screen
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
i was using it.. i will try to downgrade to stock android 11 and use my magisk delta patch from the other tab a7. they both have same specs and country code (32gb t500)
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
i did that
[Samsung Galaxy Tab A series Guides, News, & Discus] wEER1234:

hello everybody

I have a T500, I followed the OP procedure, but I'm stuck with that damn vbmeta protection.

My bootloader is unlocked and greyed out after the first stock reboot, Installed Magisk (latest Canary release) patched AP, turned off the tablet, put in d/l mode, with Odin I flashed BL/patchedAP/(Ihave no CP, it's a wifi only)/CSC. Flashing goes fine, it reboots, I have to choose language and location, reboots once more and BAM! vbmeta "security error". I don't know what to do...

please help me...
[Samsung Galaxy Tab A series Guides, News, & Discus] hamudistan:
Look here https://github.com/libxzr/vbmeta-disable-verification

Download img and flash in twrp
[Samsung Galaxy Tab A series Guides, News, & Discus] bYOndo:
I got it working, thanks!

It seemed that Magisk didn't patched (or did it wrong) vbmeta.img . I extracted manually from the patched AP file, modified under Linux with the nice utility from @hamudistan, zipped with .tar extension. Then with Odin I flashed exactly like described in the OP but unselect "reboot after flashing", so I could reboot the tablet manually on d/l mode a second time and finally (re)flash vbmeta.tar on the AP slot. After that everything worked as expected! Now I'm on Lineage OS 20 and it's like having a mint new tablet :)
[Samsung Galaxy Tab A series Guides, News, & Discus] TheHeroBilly:
any idea how to do this from windows? I don't have access to a linux machine, and I can't run anything from the device itself? I'm getting the Security error when patching from Magisk
[Samsung Galaxy Tab A series Guides, News, & Discus] TheHeroBilly:
So now the issue I am getting into, I finally got around the vb issue, and had to resize the system partition, and now I have no magisk anymore, but the gsi image doesn't have magisk? I'm going to try to patch that image, but I am unsure it that will work.
[Samsung Galaxy Tab A series Guides, News, & Discus] talksickisil:
What exactly are my options if I ended up on this rom with the only issue being no wifi connection on my sm-t500? I started with the stock rom with magisk installed. after flashing this, magisk is listed in my list of apps but I can't update it without internet or really do anything without internet. Do I need to go flash a stock firmware and start over? Thanks for your help in advance

Cant flash magisk delta canary with odin, it doesnt put anything in logs and when i tried to flash it, odin crashed, luckily the BL flashed so i was able to get it working (this is with another tab a7 t500) it worked with an odin patch
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
https://www.androidfilehost.com/?fid=14655340768118441211 this has a vbmeta disabler made for the t500 from this post https://xdaforums.com/t/rom-sm-t500...4-2020-lineageos-19-1-and-twrp-3-6-1.4421365/
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
i got it working! i just needed to change to odin 3.13 b (an odin mod) and needed to flash disable vbmeta in userdata when flashing magisk delta otherwise it would be stuck at 8gb internal storage (gets reversed with stock rom) and i got it working! this one has a screen replacent but still works perfectly fine!

just make sure to install magisk patch (as ap) with bl and csc (and cp if included) then this vbmeta disabler: https://xdaforums.com/t/rom-sm-t500...4-2020-lineageos-19-1-and-twrp-3-6-1.4421365/ in userdata.

then in the rom, magisk needs to repatch itself after installing the apk so make it patch directly onto system partition. (just restart before you patch it just in case watchdog kicks in and bricks ur tablet) then click reboot after it patches and install the watchdog brightness fix) you still need to be really fast. also pixel experience android 13 works fine now.

Good luck everyone!

Hi all, I did everything as stated in the updated guide, but I'm stuck in the pixel experience setup (haven't been able to finish it in order to install Magisk and the watchdog fix) because there is no way I can set up the face unlock. I know that it is not supposed to work on A12, but I can't seem to be able to bypass this step in the setup. As such, the tablet (T500) reboots constantly. Tried it with bot A13 & A12 pixel experience images. Any ideas on how to bypass the face unlock setup? Thanks in advance
