i am using T220, i want to install lightweight android rom for better system performance
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.

✓ How to create Magisk patch for boot.img + vbmeta.img
  1. extract (vbmeta.img.lz4 + boot.img.lz4) from your AP Stock
  2. create compress one file xxx .tar with 7zip
  3. move (vbmeta.img.lz4 + boot.img.lz4).tar (xxx.tar)from step 2 to tab a7 lite
  4. install magisk.apk on you tab a7 lite
  5. patch the tar file from step 2. (with magisk manager)
  6. result magisk-patch file at Tab a7 :-Download folder.
3. create one tar file ( include boot.img+ vbmeta.img + twrp.img) disable auto reboot of odin
( 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
