    820-00165 never fully boots SSD/USB

    So got a 820-00165 here which had a power issue. Liquid found around U7600 replaced that and fixed a trace that lead from pin 15 all the way to D8185. Now it actually powers on, chimes and shows the apple logo. Now I seem to be facing an issue of when I've successfully booted into the OS and...
