Hi @physwizz, thanks for your response, unfortunately I ended up on a "SECURE CHECK FAIL..." screen and the phone won't boot.

The steps I made were:
- Installed stock rom (A207MUBU3CUL1)
- Unlocked bootloader and flashed via Odin the recovery you mentioned.

Is there a way to fix that or just need to flash stock again?

I tried to get into bootoader by pressing PWR & VOL+, PWR & VOL-, PWR & VOL+ & VOL-, but I'm always getting that screen..

Looks I get this error when flashing recovery.
Do I need to flash AP only or AP plus the rest of the stock rom (BL/CP/CSC)..? (Have seen some users patch boot with magisk and replacing the stock with the patched AP)

Does the galaxy A205U have a root method yet? Just wondering what I can do with this phone.
