iPhone 4 charger NOT working even after replacing dock connector
I've been experiencing some problems with my iPhone 4 NOT charging or syncing with computer. After narrowing down my options: Firstly I cleaned the port with Air spray "no luck", Secondly I swapped the Battery with my friends iPhone 4, I realized the battery was perfectly fine. Lastly I believed the issue may results from internal dock connector component, therefore requiring replacement.
After replacing my Dock connector today the problem still persists, which suggest the fault may not have been the Dock Connector. I would appreciate if anyone can give me any suggestions on what else i can try.
Esta é uma boa pergunta?
