My phone fell to the floor a few times and now it freezes a few seconds after startup and turns off and on again for infinity. then i replaced the battery and put the phone together, still the same issue. now i found out, that whenever i the mid frame is screwed to the device it has that issue, but when i remove the midframe it works. seems like something is shorting? how can i find out, what is causing this problem? it never came in contact with water thank you in advance
Is the mid frame bent? Maybe try unplugging everything on the logic board then plugging it back in, could be a loose ribbon cable. The battery is the most likely culprit if the connector is damaged or loose on the battery cable itself.
