What is wrong with my c902?

Download and install this driver on your computer,take the needle and clean usb connector on the phone(golden contacts) ggsetup-2.2.0.11.exe
Remove battery and wait 5-10 seconds then insert it back and don't switch ON the phone.It must be OFF while you connecting it.
Then try again to detect phone.
If the phone can't be detected with any software or tool it is hardware problem so you must take it to some private repair shop.

Hi Sir satch,
well i already did the cleaning.... it didn't work at all... the cable works good on my other phone... and the computer can detect my other phone... :( but when i plug in the c902... it shows the usb menu like phone mode, media transfer, print, mass storage... but when i select one nothing happens as if the phone does not anymore have its drivers to connect to the pc.. :( this only happened after it was unlocked and additional is.. after it was unlocked i can't charge anymore my battery anymore.. :(
im sooo depressed about what happened :(
do you think this is still repairable?
please say yes :(
thank you for your answer...
