Hi bhogendra75,
Welcome to the Community,
I agree with your concern but if an authorize service center says so then there is a little chance of getting it on road,But if you still think that there is no liquid damage then you can try a few things to reassure yourself,and I also think that there is no problem in trying,So we can just try for that have a look :
1.First make sure you have your backup.

3.Installing OS on your device :
Credit sdgardne :
1) Uninstall, from your PC, any BB OS packages
2) Download BB Desktop Software  BlackBerry desktop software
3) Download and install, to your PC, the BB OS package you desire:Carriers ( but make sure it is of the same device model)
4) If that OS package is from a carrier other than the carrier for which your BB was originally manufactured, then delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
5) Launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC. If, during the process, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.
Don't forget to backup.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:
