Hello Everyone,
my Defy plus is not detecting on PC, when i plugged in the USB only phone light is turning on no led light no charging. i tried connecting rsd lite nothing happen. i m using windows 7 latest RSD-lite some 5. version and latest drivers. i have installed SBF before but its not connecting now. it happen after i installed White-rabbit ROM 1.5.2 i was using 1.3 there was no problem. everything else is working good.
I even installed stock ROM and older white-rabbit ROM's but same problem exists.
when i plugged charger its working good.
Tried almost everything formatting, factory restore, nothing working.

is it a hardware problem...? my phone is still under warranty.

Most likely HW problem. Especially if you tried several ROMs.

I had been to the service center they say that its a motherboard problem..They have sent my phone to main office in chennai i guess..I have installed stock rom i restored it through CWM but cant unroot because my USB was not working...?

will there be any issues if the phone is rooted...??
