How to update from MR2 1.66.605.2?

[syntheticnation]

Over a year ago I updated my Thunderbolt with MR2 1.66.605.2 (Android ver. 2.2.1) because I was getting constant reboots and there wasn't an OTA update in sight.  BUT, since then, I have never gotten any OTA update notifications and it doesn't find updates when I check for new ones.  It's about time I update my phone, so how would I go about this?  I'm having a hard time finding download links for firmware to update to.  Under software status, the only information listed is...

Everything else is blank.  Probably why it isn't finding new updates on its own.  Here's the full information on my current software.

Android Version: 2.2.1

That's really strange, syntheticnation!
Can you send me a direct message with your mobile number and MEID. We can see what we need to do to get the update to you?
Did you purchase the device from us?
