already done , but without luck
iam not stupid, i had 3 sgs2 and this is first problem like this,
in service they told me that i have to pay for diagnostic first,( so no good )
iam without waranty, but if i chanage usb port flex cable iam not shure if this one can fix,
as i didnt know about history of phone ( maybe was water damage ?)
but all working like charm, phone looks like new( except USB connection)
so why the USB JIG working ? which pins is connected via JIG?
Also charging is good , some circle can be broken?
