I'm sorry if this has been asked before, I tried to find the answer (with no luck). My friend has the TB and I installed the MR2 a few weeks ago (her phone was restarting about 4-5 times a day). Now, I've read if the MR2 is installed on your phone you will NOT receive the update. Is there any way to reset the phone to the previous radio (prior to the MR2), or will I have to due a factory reset. Thanks in advance for your help.
Update Thunderbolt with MR2 installed.

Ok, maybe someone who knows more about this may be able to chime in, but...
First off, I doubt a factory reset would work. A factory reset just wipes all data, but doesn't actually revert your software version to its original factory version...it just leaves you with a refreshed, "blank canvas" of whatever software version you're currently running.
What you can do, if you can deal with a data wipe, is install the full RUU of the new MR2 update. This will pretty much do the same thing a factory reset would do, but leave you with the newest software version.
XDA post where I found the MR2 RUU (with download):
[RUU LEAK] Froyo 1.70.605.0 Radio 1.39.00.0627r - xda-developers
and the original source, with install instructions:
[Exclusive Download] Leaked 1.70.605.0 Update For The HTC Thunderbolt (No, It's Not Gingerbread)
Is there a way for you to upgrade the radio without losing data? To be honest, I don't know. I believe you need to be rooted to flash radio files, so I'm guessing the answer is no, but once again, I don't know the definitive answer to that question.

Assuming it is unrooted, you should be able to install the "official" MR2 RUU. It'll erase everything and you'll have to set up everything from scratch but that'll be the case for any route you take. You should be able to just use the new MR2 RUU [url=http://www.androidpolice.com/2011/07/08/exclusive-download-leaked-1-70-605-0-update-for-the-htc-thunderbolt/][Exclusive Download] Leaked 1.70.605.0 Update For The HTC Thunderbolt (No, It's Not Gingerbread)[/URL]

Your best bet is to just flash the new [Exclusive Download] Leaked 1.70.605.0 Update For The HTC Thunderbolt (No, It's Not Gingerbread)
You don't have to be rooted as you prob already know. Or you can flash the original radio file and wait for the OTA to make it to the phone.

How do I flash to the original radio? I do not want my friend to not receive OTA especially with GB is finally released.

If your friend flashes the RUU, the phone will be indistinguishable to Verizon/HTC's servers, thus allowing the phone to receive all future updates.
