then you should uses manual by disable auto reboot from odin option and press and hold power + vol up
(the main reasons for me to used twrp cause I only want Fastboot mode from it.)
but now i m on android 12 and switch to uses CustomAP file for odin fashing only.

yes it hard to press button between installed twrp , then i used "vbmeta disabler" but didn't test with 220 . t225 is work well.
yeah just goes to black screen. unfortunate. green bar at top and then black screen no twrp
use magisk patch version ? if used another version from 24.0 try patch with this version.
twrp first install must uses magisk patch.( boot.and vbmeta) cause stock formware will erase your twrp and replace it with stock recovery.
no you can install both with the same time .
extract: boot.img.lz4 + vbmeta.img.lz4 from Stock AP and patch its with magisk 24.0 . bra bra bra read my tutorial ....
i do not understand top part on top twrp install, what programs do i use? or how to recompile into .tar?

✓ How to create Magisk patch for boot.img + vbmeta.img
- extract (vbmeta.img.lz4 + boot.img.lz4) from your AP Stock
- create compress one file xxx .tar with 7zip
- move (vbmeta.img.lz4 + boot.img.lz4).tar (xxx.tar)from step 2 to tab a7 lite
- install magisk.apk on you tab a7 lite
- patch the tar file from step 2. (with magisk manager)
- result magisk-patch file at Tab a7 :-Download folder.
( do this if you already flash stock Rom)
-flash new tar file at AP Slot.
after odin finished its job.
-press power + Vol down for restart after restart saw yellow text immediatly press power + Vol up...... if you saw black screen try to press vol + And then vol down for activat twrp screen
do action for install twrp.

Remember this is in early development (alpha)
- Not Working:
- > Adb Sideloading
- > Vibration (minor issue)
- > 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.
- Install Instructions
- Flash TWRP from Odin on AP Slot & Hold Volume Up + Power while flashing until TWRP appears.
- Go to Advanced > Terminal and type "multidisabler" (without quotes", then data wipe.
- 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.

Nice, it's good to see someone owning the device developing for it, I was mostly "blindly" doing stuff and then asking Skorpion to test them.22
