[Motorola Edge 20 Pro] datocavalcante:
Hello, I'm from Brazil and I bought a Motorola Edge S pro in china, it came with a custom rom. Unfortunately a bank application had problems, so I changed the rom (to stock-rom). However, in this game of messing with the rom, I ended up giving the command fastboot flashing lock via the command line and with that, I ended up locking the phone at boot.

Now whenever I try to rewrite the rom, an error occurs. The device does not accept the fastboot flash command because I ended up crashing earlier. I've tried to recover with motorola rescue but I can't, because I have no way to activate the developer options, because the device does not start. The only access I get is via fastboot but I don't know the procedure to let it accept flash again via command line.

Any tips on how to recover?
