Galaxy S2 i9100 Data usb faulty.

Hello.

I have one problem with this phone.

First, do not charge and is not recogniced by Windows.

Opened and cleaned oxid with one by-pass the phone charge the battery perfectly.

But one problem, if I conect the charger or an usb adapter the phone is always on MPT mode and Windows can not recogniced it and D- and D+ are in shortcut, if I do not connect anything D- and D+ are not in shortcut.

Is the 6pin IC U502?

Can solve this only with replace the little board or can be a problem with U504?

Thank you very much.
