  • iphone 7 display connector practice

    I desoldered and restored the display connector as practice
    prior work Baseband IC practice removal/restore✔
    • seated resistances✔
    • components did go floating(see pictures) I restored them restoring normal seated resistances
    • chestnut voltages missing
    • current behaviour PTB USB goes to 190mA - 210mA stays there
    • Not recognised by computer
    • No image
    The hilighted areas in the pictures are where I was working.
    I reflowed chestnut in an attempt to restore chestnut voltages✘

    My strategy would be to desolder chestnut and leave it off until I resolve the booting issue
    What do you think I may have done to cause the problem?
