Ohh Sorry. Forgot to update you. Btw thanks for help . LG near my place said the device isn't turning on even after inserting new battery so I thought shipping it to LG US for RMA will be best option.
Update : LG USA refused to repair the device and returned it as it is saying some Epoxy cracked and the device is not repairable [DOUBLEPOST=1405185004][/DOUBLEPOST]Mods can close this thread.
Its all over now.
