As you can see from the service manual, when insert USB, must present +5volt at L7022. Check it.



Post result.

Hmmm..... Very strange - need help and no any answer to help. It seems to be you don't know how to open your phone... OK, lets start. There are many ways how to do this - https://www.youtube.com/watch?v=7zEglt5ATig
Learn it now, and select more useful for you. As for me - more useful info from ArtCom.Lab. But anyway, try to open phone until this stage -



Don't disconnect HDC8000 at first. Insert turned on USB cable to USB socket and check - is there 5 volt at L7022? If no, then clear HDC8000 during reconnect process and try check volts again. If also no volts, then decide: if no any other problems with Sub PBA, you can solder thin wire to Vbus pin of USB socket. Place thin wire near red and white coaxial cables, then forward it to L7022 and solder. Check L7022 itself with m/meter. Take notice to take care against any shorting, for example - thin plastic pelicle. Put phone board to the place, connect battery, LCD, touch, no insert SIM slot and don't turn on phone. Only insert USB cable and post what do you see...
