Hi ,sorry for the delay on answering  ,  i Finally! ,  found some time to spend on this board  , , yes thats correct the phone booted up fine and charged .   I tunes does not see it when plugged in  .

I put the shields back on by just touching the solder points with the iron tip , i thought maybe i pressed down a bit hard to get the solder points to line up (breaking the U1600).

I had a good look around the board for dislodged components as you suggested and found R78 was dislodged so i put that back on and was kind of hopeful but still same fault ,

i checked the voltage on PP_BATT_VCC :

These are all the components on that line , do i need to test voltage at all the components on a line   to check a line ?

.

L4    3.8V

C332   3.8V

C333    3.8V

C337    3.8V

C3337    3.8V

C387     3.8V

C386     3.8V

....

PP3V0_ACC   is there and PP5V0_USB_PROT

the voltage on these lines fluctuate on and off with the amp draw on the psu .
