I faced a similar problem but mine was caused after I used the boot warning remover trick on the android 12 s/w
I let the battery run out of juice so my device turned off then I charged it for a bit without turning it on and when I tried going into download mode I was able to so I flashed it again and now it's fine
I know , let me know how is the performance , can the wifi be picked up in a remote location ?

I use the tab mostly for reading ebooks and stuff so can't tell much about the performance however it seems slightly slower than 11 like apps take a bit longer to load up
Also there aren't many changes in the ui itself so no visual improvements
Even the material u thing of Android 12 with the whole color picker thing is not available they just have 4 preset pallets to choose from
Overall I won't recommend upgrading

As for wifi the reception seemed lower than before, on 11 I would get 3 bars on wifi and now in the same place it goes between 1 and 2

But did you do a fresh install? Meaning a factory reset after doing that major update and then letting the ROM settle for a few days until the Dalvik caching completes.

Nope I kept my data my tablet came with a ton of restrictions 😂 so I'd have to go through the whole frp bypassing, uninstalling knox while the tab wants to restart and stuff therefore I just kept everything as is

Upgrading it will increase system space but it will probably solve the problem of not flashing gsi on twrp

Anyway, I don't want to upgrade to one ui 4.0 because one ui 3.0 performance is already bad

So I have a few questions
1. Does this work properly on a device with the One UI 4 A12?
2. Is it necessary to use Odin or something like flashify can be used as well?
3. Any specifics? Like using only certain version of magisk or certain firmware build etc

You say the device goes black after flashing?
My device has been bricked for a week, now I'm trying to remove the device's battery

/* * Your warranty is now void. * * I am not responsible for bricked devices, dead SD cards, * thermonuclear war, or you getting fired because the alarm app failed. Please * do some research if you have any concerns about features included in this Recovery * before flashing it! YOU are choosing to make these modifications, and if * you point the finger at me for messing up your device, I will laugh at you. */

Remember this is in early development (alpha)
  1. Not Working:
  2. > Adb Sideloading
  3. > Vibration (minor issue)
  4. > Other Problems: Sometimes when you boot recovery touch not works and only solution is to re-flash TWRP again from Odin, this is kernel issue, we need custom kernel. I found out that in that case you can reboot with usb otg and mouse connected and twrp could start working on next reboot.

  1. Install Instructions
  2. Flash TWRP from Odin on AP Slot & Hold Volume Up + Power while flashing until TWRP appears.
  3. Go to Advanced > Terminal and type "multidisabler" (without quotes", then data wipe.
  4. Now reboot into system, after completing first setup of the device reboot into TWRP again to see if you can see the contents of your Internal Storage, you should, if yes you have successfully disabled Samsung encryption of internal storage.

I have the N variant
Does Twrp for T225 work for T225N ?
What is the meaning of N or the diff by the way?
