nah you can always downgrade via ODIN. Just flash the oldest stock firmware file you can find for your phone and you will be able to unlock with no issue

not possible

It doesn't downgrade

I tried it does't go back even if you flash back

ODIN flashes it with success signal but when it reboots
it goes to initialising recovery mode however what i think
that's where it finishes half way and reboot, the baar doesnt complete

and reboots without giving any message

The point is, its not allowing to FLASH back to other rOM
