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.
- 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
Didn't think you could use that dial in code on a Thunderbolt. It would work other android that are not LTE or smartphones! Tried that on mine and never did anything but lock it up and had to do a battery pull. To get get mine to update I shut it down and pulled the battery,sim card,and SD card then waited for about 5 minutes. I then put it back together restarted the phone and waited a minute or two for everything to load and then went to settings,software update,check new and it found it
The checkin code works for the Thunderbolt. It is the activation code *228, options 1 or 2 that are not needed for Verizon phones with 4G LTE SIM cards.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
