I've had a thunderbolt since it was released and have yet to recieve an operating system update. Clicking 'Check New' under software updates opens a dialog that says checking for updates. After a few seconds the dialog closes with no message or update.
I've tried:
-battery/sim pull
-Factory reset
- LTE ONOFF to toggle 1x/3g/4g
- Calling the CHECKIN number
My android/software version are:
Android version - 2.2.1
software number: 1.13.605.7
Any ideas?
