Install failed, can´t boot.

Hi!
I followed the process on https://pixelos.net/download/oscar but when sideloading the OS it stopped at 39% and gave an error message.

adb: failed to read command: Undefined error: 0

Tried older version and a different PC. Same error, different percentage.

Now I can´t boot.

Any help at all would be really appreciated, my wife is going to kill me if I confess to having ruined my phone so you could be a hero and prevent a murder, you could be Batman.
