I'm trying to unlock the bootloader of my old Alcatel OneTouch Idol X+. I got to the point where my phone would ask me to press volume-up to confirm that. Due to a bug of which i read several times now, the volume-up key won't work now.
I tried using that adb input keyevent command, which wouldn't work in fastboot mode. Are there other options, or some way to use adb commands in fastboot mode?
