Default [Q] HTC One S stopped working. Help

I have a HTC One S cell phone that stopped working after I did a software update from the settings menu. The phone has no service (not able to connect to the network). My service provider is Wind mobile. They tried a "hard reset" or factory data reset this did not solve the problem. Then I had a technician replace the firmware and downgrade to an earlier version of software. This got the phone to work. I was able to make one call. However I was unable to pickup wifi. I tried to turn on wifi in the setting menu and then the phone stopped working again. I have tried talking to HTC customer service but they have not been able (or willing) to help.

Does anyone know how to fix this phone?
I suspect that either the firmware installed incorrectly or is the wrong version for the phone.
Does anyone know where to get the correct version of the firmware?


Thank You,
