I am trying to install Ubuntu in my tablet, by both means of the UBports tool and the command line.
The UBport tool fails and says:
failed to get download permission for partition 'recovery'
If I try the command line, in the first command to try, fastboot oem unlock, I get stuck. I get the messages on the tablet screen (do you want to proceed? Press volume up to say "yes"...), but I do not get any response from the tablet. The fastboot command gets lock in my computer (Ubuntu 18.04 LTS).
I have activated the developer mode, USB debugging and I have disabled the OEM lock.
Apparently, I am not able to unlock the OEM, does anyone know how I can unlock it?
