  • iPhone 7 bootloop issue

    Hello everyone,

    I have an iPhone 7 that I replaced the screen on this morning and the phone booted properly with no issues at all. Gave the phone back to my customer and he left. He then came back about 4 hours later with the phone now stuck in a bootloop. I took it apart and plugged it into my power supply and I am getting a hang on .334amps after about 20 seconds of it going up and down but it never makes it higher than .4

    I don't see any heat on the phone and I have attempted to unplug all external pieces from the board and I still get the same thing.

    Any ideas?

    Rule #1. Put the board with known good parts and see what happens. Known good (not new, known good--meaning recently proofed with another phone) charge port, charged battery, and screen. Nothing else. What happens?

    If still the same, then try restore. What happens?
