Chosen Solution
So, they gave me a p9 lite to check as it was getting pretty hot and it’s fingerprint scanner wasn’t working. Opening it revealed a disconnected scanner and no thermal pad. I plugged it in and it started bootlooping. Cache clear, factory reset and flashing the proper rom from a sd card didn’t solve the issue, what can i do besides getting a new motherboard?
So, i fixed it. What i did, was buy another cheapo broken p9 lite for parts. When I swapped the motherboards, both phones were working for some reason, but when i put mine back in it didnt, until i swapped the fingerprint scanners aswell. I have no idea why or how this works, but it fixed it for me.
Absolutely nothing. You can’t even put custom roms. They LOCKED the bootloader unlocker Update (06/08/2019) https://forum.xda-developers.com/p9/help…
