The phone I suspect has a motherboard issue. Suppose it's a motherboard issue and I replace my motherboard. Could I recover my files from the old motherboard? The battery is good and the buttons are good. It can't turn on. Sometimes does when leaving it in the charger. It brings up this blue screen which says "updating" or something similar although it wasn't updating. The night before, the phone's battery finish so I plug it in and go sleep then I wake up. The screen is frozen on the battery icon. For 4 months.

imo unlikely to recover data, usually its the nand chip that has corrupted

Aight

Impossible to recover
