The device was off I suppose, since it was booting by itself, but the screen was off, so I think after a while it powered itself off. I pressed the up button for like 30 secs and than while keeping it I plugged it to the laptop and magic, the laptop recognized it as QDLoader. I tried several times before but it didn't work, dunno what changed this time.
Yes I am installing google manually.
Yes, I bought it from Banggood and they took the liberty to unlock the bootloader and install a custom ROM, but I wanted the original one (since the ”global" didn't have updates and some features)
