If you can’t wait for Verizon to fix the issue, xda provides the following fix that will get you back on 3G speeds until the network is fixed. Personally, we are just using WiFi today, and hoping for a speedy recovery.
How to Fix 4G Outage on HTC Thunderbolt
Keep in mind you’ll likely need to change this back to get your phone back to normal after the nationwide Verizon 4G LTE outage is fixed.
The issue has cut speeds down from the incredibly fast speeds we are used to back to near dial-up speeds of 129kbps down and 151kbps up, compared to the normal 4G speeds that are measured above 12MBps down and 5MBps up or higher.

OK if any of you out there have done this change to your phone to get 3 G service while 4 G service was down just reverse the steps and then pull the battery out for 15 -20 seconds to do a soft reset and re-install battery and turn phone on you should have 4 g service again I did it and it works.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
I got mine to go back to eHPRD. ?? Used the steps in reverse as well. Try it again.
So under Settings-About-Network, yours says eHRPD for Network Type? Are you in a 3G-only area? I had mine set to eHRPD and went to bed with 1x, woke up with 3G but it's Rev-A as the network type. Still shows rev A after switching it to enabled rebooting and then switching it back to eHRPD.
i just used wifi all evening and when i woke up this morning my 3g and LTE was back!!!!!!!! i'm begining to wonder how we all survived a mere 3 or 4 years ago....lol
