The same response …
I think and maybe it’s (total bullshit) that I have no OS left on my phone so the device can’t be connected to the pc as no Driver exist for nothing ?
I don’t know… and the only one that seems to had the same problem as me (Easy Installer failed - Fairphone 3 blocked on fastboot mode) just erased the phone before re-installing the fairphone os. But what does it mean to erase the phone ?
