Changed my mind, i wanna overclock to default stock os performance as its lower than normal on cpu 0 to cpu 4 at 614, normal is way higher
Huh, I'm not sure why but I'm unable to replicate my own thread, I get bootloops instantly,and I'm currently back on one ui 4, I'll let you know when I'm up on a gsi...
Here,

I didn't try the A13 builds, so, I suggest you to download the latest Android 12 GSI from the above link
Would this work?

Did you unlock the bootloader and did you install it with the internet when the device was turned on?11 -
4Just before we get started, I would like to say that you will not brick your device if you follow the steps as is without any, and I mean any deviations.
Read what works and what doesn't first!
Okay, enough preface, let's jump right in!
Firstly, pre-requisites(hardware):-
1.A micro SD card
2. A windows PC, windows 7 or later (32 or 64 bit)
3. A USB Type-C cable
4. A galaxy tab A7 running the latest one ui 4.x build
Pre-requisites (software on PC), you'll need:
1.Stock firmware:
Download the latest firmware from hereSamsung Galaxy Tab A7 (LTE) Firmware Download SM-T505 Free Download
Samsung Galaxy Tab A7 (LTE) Firmware Download...samfw.com
1.1 After downloading it, extract it on the PC and copy the AP file to your micro SD card, as we need it on the tab later
2. Samsung USB drivers
download them from here and install them on your pc, it'll take a while but it's essential for this process
https://developer.samsung.com/android-usb-driver
2.1 Reboot your PC after installing the drivers
3 Download the twrp.img from below
https://forum.xda-developers.com/t/...axy-tab-a7-10-4-sm-t500.4358595/post-87038713
(Yes, correct, download the .img as we won't be using Odin to flash custom recovery)
Copy this to your SD card as well
4. Download Canary apk of magisk delta from link below
https://huskydg.github.io/magisk-files/
Copy the apk to your microSD which has the previously extracted AP file
5. Download dynapatch from the file attached below credits to @redymedan for developing this!
Then move it to your micro SD card
6. Download the GSI image of your choice, and (make sure that it doesn't exceed 3.3GB after extraction) extract it from .img.xz format to .img format and then copy it to the micro SD card
(also, if it exceeds 3.3 GB, don't worry,follow the steps in important notes on how to expand your system partition to accommodate larger GSIs...)
7. If your gsi doesn't have gapps or you want to flash a system mod then download a vndklite variant of your gsi, as system is mounted as RW in vndklite gsi, where's system is mounted as read only in normal gsi images
8. Download Odin and extract it
https://samsungodin.com/
9. Download SmartPack kernel manager apk and copy it to the sdcard too
https://github.com/SmartPack/SmartPack-Kernel-Manager/releases
(We will be using this to flash twrp in a later step)
10. Download the brightness and watchdog fix module from below
Copy it to SD card
(Optional) 11. If you don't want your install storage encrypted, download the following two zips and move them to SD card,
[Pie/10/11] [System-as-root] Multidisabler: disables encryption, Vaultkeeper, auto-flash of stock recovery, proca, wsm, cass, etc.
The multi-disabler started life on the Exynos...
forum.xda-developers.com
https://zackptg5.com/downloads/archive/Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip
Process to flash GSI:
1) Unlock the bootloader
To unlock the bootloader, follow the steps from here...
https://forum.xda-developers.com/t/...4-unlock-bootloader-root-with-magisk.4185993/
2) After that patch the AP image we copied to the micro SD card earlier and then copy the patched ap to the micro sd card and then to the pc. Steps of patching can be found here
https://forum.xda-developers.com/t/...4-unlock-bootloader-root-with-magisk.4185993/
3) After patching the AP image, copy the patched image from downloads folder to your micro sd card
4. After that turn your device off
5. After the device is fully powered off, hold both volume up and volume down buttons simultaneously and connect it to your pc, then click volume up button once during the prompt to enter download mode
6) After entering download mode, select the BL, CP, and CSC (do not choose HOME_CSC!) files from the extracted firmware, after doing that, for AP, select the patched AP file we copied earlier and then click start on Odin.
7. After the flash is successfully finished, reboot your device and set it up, after setup install the magisk Canary apk from the micro SD card
8. After installing the apk, open it, and click 'OK' on additional setup prompt and the device will reboot after a few seconds
9. After the reboot completes, install the smart pack kernel manager apk we put in the SD card earlier, then open it, then, navigate to
Tools>Backup>(swipe to the right where it says "boot partition")> it changes to recovery partition> click on the plus symbol> two options show up, select the flash recovery option> select the twrp image from SD card (file manager opens automatically)> click on "select" and then flash it...
10. Then open magisk delta app, and reboot to recovery
11. After rebooting to recovery, flash dynapatch
12. Then reboot to recovery (very important)
(Optional)12.1 Flash multidisabler we downloaded earlier, along with disable dm Verity to disable FBE on integral storage. Also, if you intend to disable encryption, do flash both the zips not one.
13. Then select install>Micro SD Card>install image> select GSI image you downloaded> select System Image > swipe to flash, then factory reset and wipe data from within twrp (thank you @shorty9210 for the factory reset part!)
14. Here, hectic nature of you must be used...
15. Boot to your GSI, and set it up as fast as possible as a watchdog crash is triggered every 30-50 seconds which causes a reboot
16. Install magisk apk and reboot for additional setup
17. After reboot, open magisk and install the brightness and watchdog fix module
18. Reboot the device after installing module
19. At this point you won't get random reboots
20. Now you can enjoy your GSI...
Now, onto what works and what doesn't...
Working:
Boot
Touchscreen
Sound
WiFi
Bluetooth
Mobile data
Camera
Microphone
Doze
OTG
Power buttons
Volume buttons
Charging
Rotation
Gyroscope
Calling(works with VoIP)
Not working:
VoLTE
In call audio (in case of Sims)
Auto brightness
Offline charging
Untested:
Cast
USB tethering
MTP
Tested roms:
1. Trebledroid GSIs (don't use, as magisk doesn't work and gapps can't be properly installed for some reason)
2. Pixel experience ( magisk works and it's stable after running the watchdog command)
3. Google GSI (vanilla and Gapps, not recommended, due to it being extremely barebones and not having fixes for DT2W, and headsets)
Now credits!
To team XDA for keeping this forum alive and well,
@phhusson for developing GSI images that actually made this possible
@topjohnwu for creating magisk
@agreenbhm for the TWRP image and for helping me,
@duyfken for correcting the firmware links, and also, for informing me to add the type of GSI for this device!
@shorty9210 for a correction
@huskydg for magisk delta development
And finally all other members of XDA for taking interest in the modding scene,
Thank you!
I'm quite new to the GSIs as a whole, so, I still can't find any workarounds for issues, I can only list them for everyone to know...
Important notes:
1. If your GSI has phh settings, do the following...
1.1 Enable double tap to wake
Settings>Phh Treble settings>Samsung features >Tick "Enable difficult tap to wake"
1.2 For making headphones work,
Settings>Phh Treble settings>Misc features>Tick "Use alternate way to detect headsets"
Also, Enable developer options>Enable "Disable Bluetooth A2DP hardware offload" and restart when prompted
2. If the gsi ROM you're trying to flash doesn't fit on current system partition, then,
*This process will wipe your system partition and will reset your recovery, so, keep the dynapatch zip and gsi image on hand, you will need it!*
Download latest platform tools from AOSP site, link below
https://developer.android.com/studio/releases/platform-tools
https://forum.xda-developers.com/t/...xy-tab-a7-10-4-sm-t500.4371123/#post-86050459
a) download the product.img from above link
b)Reboot to recovery from magisk app, then, in twrp, click on 'Reboot' button
c) click 'fastboot'
d) the device will now reboot and then after a few seconds, a twrp ui will appear with the text 'fastboot'
e) connect your device to a pc with the latest version of platform tools and drivers installed
f) run these commands in order
fastboot flash product product.img
fastboot erase system
fastboot resize-logical-partition system 3940000000
fastboot reboot recovery
g) after doing so, again reboot to recovery, flash dynapatch zip first
h) again reboot to recovery and flash your gsi image
i) this time images up to 3.9GB will be flashable
j) no need to format data if you're flashing same rom
And that's it you'll be able to enjoy bigger ROMs on your Galaxy Tab A7!
3. follow steps from here to get 4-speaker audio!

[ROM][SM-T500] Samsung Galaxy Tab A7 10.4 (2020) - LineageOS 19.1 (and TWRP 3.6.1)
Hello world, I have successfully built...
forum.xda-developers.com
4. Previously, we had to use either some magisk modules or SmartPack kernel manager to enable swap so that the device won't crash under load, but, now, 2GB of swap is allocated by default, which is plenty sufficient for daily usage, so, i recommend you not to use any modules or services that enable swap....
5. If zygisk is enabled after module is installed, some users reported that it breaks brightness fix, to remedy that, try flashing permissiver_v5 from below in twrp
Permissiver_v5.zip | by erfanoabdi for Generic Device/Other
Download GApps, Roms, Kernels, Themes...androidfilehost.com
6. Also, please do not rely on extra dim if brightness fix module won't work, try above step , i did this previously and the edges of my screen got ruined(ghost imaging) due to the heat...
7. Please refrain from using any modules that spoof the device identity as it causes the phh Treble app to not display "Samsung features" at which point you can't use DT2W, so beware...
8. Recommended settings in magisk delta
a)magisk delta>settings>hide magisk app, you will be prompted to allow magisk delta to install apps, allow it and start the hiding> now, the magisk app will be under an alias you chose
b)magisk delta>settings>Zygisk(enable)
c)magisk delta>settings>Bootloop Protection (enable)
d)magisk delta>settings>Magisk Hide
9. Passing safetynet on Gapps GSIs
a)magisk delta>settings>Configure MagiskHide> now, tap on three dots, elect show system apps>then tick the boxes next to the following apps
Google Play Store, Google Play Services, Google Services Framework
b) Install the magisk module "shamiko" version 0.5.2, as later version causes Google services to crash... Download link below
https://github.com/LSPosed/LSPosed.github.io/releases/tag/shamiko-120
(Optional) You can also install this module below after installing shamiko for a higher chance to not fair safetynet randomly...
c) After installing the module, reboot
d) clear data and cache for Google Play Store, Google Play Services, Google Services Framework
e) at this point you should pass safetynet successfully
10. Just a heads up, be sure to only download GSIs from the list in @phhusson GitHub, i.e, link below,
https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list
And, do not spend money on people that claim to give the "best GSIs" or whatever gibberish they use, only spend money as a donation to a developer, if you really enjoy their work, and would like to support them to keep up thier interest!
I had to mention this to put you on the cautious side of things!
11. Taskbar height is incorrect on some roms, and the magisk module from below link fixes it, credits to @wEER1234 for mentioning this, and to @Coxxs for delaying developing it!

Hey all, it's been a long while, but here's a small peek into what I was ble to run on latest one ui 4.x vendor this weekend, I will update the future soon on how to run A13 GSIs...2Thank 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.2Hey 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!1
I didn't mention it, as I found out that extra dim intensity control does the job just fine, but I'll add it in either way, thanks!
