Hi! Ok, I have another problem. I was following @Anonyme instruction and in step 3, OEM unlock, I activated it (it appeared in developer options). According to the instructions, “activate it and don’t worry about the warning”. I activated it and the phone did a factory reset. It didn’t say anything similiar in the tutorial, but I assumed that after the factory reset the OEM would be activated. But then, after setting everything up, in the developer options there was no OEM unlock button at all, neither activated nor deactivated. I followed the advice of @0x7C0 to make the OEM unlock button appear, but I didnt appear. Any help? By factory reseting it (without internet) did I updated something that prevents OEM unlock? It seems that I’m going backwards in this quest…
EDIT: ok, it appears that after rebooting the date was again set to the actual date, so changing it some days before to day made the trick and now OEM Unlock is showing and bootloader is unlocked.
