Hi ,

I bought my first oneplus 3t phone i have no idea whats with this device.
I am not able to upgrade to Android PIE through OTA because of OEM Lock.
whenever i download the upgrade it just give me an error when installing it.

I have tried to lock the device through fast boot oem lock.
The device just keeps restarting after OEM lock them i have to unlock it again to boot it up.

I have seen many threads but i need someone to help me step by step.
