Charging problem and home,search,back,menu buttons not lighted up. Mic does not work

[sib63]

When the charging cable is connected, it starts to charge and then stops after some time. Sometimes when charged with phone off, there is no indication and cannot be started unless the cable is detached. But charges fully. Secondly, the bottom button lights (i.e home, back etc) do not light up nor is the mic working i.e the other side cannot hear me speak.
Tried changing the charging port . No use. Gave it to Service Centre (Fone Care in Mumbai). They messed it up. Infact the problem with the buttons at the bottom is their creation.
Will reinstalling the stock rom after rooting help? And for those in India, NEVER TAKE YOUR PHONE OR ANY DEVICE TO FONE CARE FOR REPAIR. They know nothing, just will fool you and waste your time and above all SCREW YOUR DEVICE.
