Repaired phone won't turn on and is frying USB ports
I recently received a xiaomi mi 9t/redmi k20 with a broken screen from a friend. I ordered a replacement display+frame and installed it without any problems but the phone wouldn't turn on. I thought it might be because the contact pads for the power button were slightly off so I disassembled it and reassembled it again. When I plugged it into my PC's USB port windows gave me a message saying there was a power surge on the USB port and my device was drawing too much power. I then tried my usual charging brick with no effect only to realize later that it had killed the charger. Anyone have any experience with something like this or know how I should proceed from here?
Is this a good question?

Is your friend's data on the phone backed up?
