I stopped connecting to my udoo neo for a while, but now that I need it, I don't remember the password, I guess do not change the udooer and root passwords (udooer and ubuntu). But I can't log in on the board. Is there any way to enter recovery mode (similar to when it is done from the GRUB in an architecture like amd64 or x86)? or some other form of brute force to recover some access code, without the need to reflashing the device?
