Strange colours all over board
A customer of mine left this iPhone 8 with me. It is boot looping. I have inspected the motherboard, and it has strange colours all over the board (looks just like a petrol spill). I cannot see any signs of damage, or any signs it has got wet. I am not concerned about the boot loop. I am just wondering if anyone has seen this before and know what causes it? I have seen it once before on a dead iPhone 7 that had a PMIC fault. Thanks
Is this a good question?
