I accidentally all Gboard layouts and can’t enter my password anymore. I do have some other keyboard apps, but they don’t load immediately after booting. adb shows no devices, probably need to unlock and allow USB debugging… I thought about connecting a hardware keyboard. How would that work?
Do you have a bluetooth keyboard? That would probably work as well… though not very common lol.
You need to unlock it to pair new devices, you can only turn Bluetooth on and off while locked. That could be really exploitable otherwise: just pair a keyboard, wait for the user to unlock their phone and install a remote control app via keyboard sequences.
