that solution did not work for me too.
try this solution
warning: if only remove filter and not change, phone WILL WORK OK, but no longer communicate with computer(you can no longer flash/read phone)

give the filter as posted by zullu2004 a good clean with cleaning solution (with a toothbrush) seems to get corrosion under filter,i had already cleaned pcb in ultrasonic bath but it did not fix it but after a good srub with a brush it worked fine.

well...let's clear it up !!!!!!!!!

Most likely is Vbat+ shorted to VExt(charging pin) , hence charging still takes place even no charger is actually plaugged in ...so to cure that ...simply clean/remove Sytem connector and proceed inspection straight to the Charging Circuit ...which makes sense from a technical point of view ..and this holds true whenever u have such a problem ,regardless ur phone model/brand.
