Then this was not the (only) reason for Revolut to complain.
You are running an Android Custom ROM. Banking Apps might complain and not work at any point in time. There’s no guarantee they will work.
Prior example (also notice how long this saga went on):
If those instructions manage to unlock and lock your bootloader as described, they work.
Yes. The Instructions are not very straightforward unfortunately. But I managed to flash lock_critical and flash lock. Nobody told me these are two separate steps for whatever reason.
It’s proven again how difficult it is for a programmer to write succinct yet complete instructions. I recommend to leave that to an AI if choice. They are generally much better, complete and understandable.
