HTC Thunderbolt MR2 update available for download now

The OTA is supposedly going to be hitting phones a little later in the month, but if your Thunderbolt is anything like mine (I had 4 reboots so far today) then I’m sure you can’t wait to get your hands on the cure.

The guys at Android Police broke this one and it is coming to you courtesy of Chingy and TeamAndIRC.

As Verizon hasn’t officially outed this update there isn’t a changelog yet, but the improvements experienced by those running it so far include:

  • No random reboots (HUGE!)
  • 3G/LTE Toggle (Settings>Wireless & networks>Mobile networks)
  • Improved signal strength
  • Improved GPS
  • New bootscreen
  • My Verizon app works properly
  • The “3G” logo in the notification bar changed (Not really an improvement, just different).

I performed the update myself and can attest that everything is working fine and I haven’t had any reboots yet anyway. The only downside I’ve noted is that I’m back to the old Android Market.

Before I get to the instructions please be aware that this is not just an OTA style update and so it will wipe all of the data on your phone. Backup anything you don’t want to lose. The update I’m linking to here is not for root users and will brick your phone if you are rooted. There are some ROMs based on this update for root users and if you are interested just hit up the source link for details.

With all of that out of the way if you are a stock user that wants to perform this update it is almost as simple as they come.

  1. Download the stock MR2 RUU file here
  2. Re-name the file to “PG05IMG.zip” (without the quotes)
  3. Move that file to the root directory of your SD card
  4. Turn off your Thunderbolt (Make sure you wait until it is all the way off)
  5. Hold the Volume Down button and Power button at the same time and keep holding them until the bootloader screen pops up (it’s a mostly white screen with the little skate boarding Androids at the bottom)
  6. Be patient on the bootloader screen as it will take about 15-20 seconds for the update process to begin automatically (This isn’t the actual update)
  7. After a couple minutes it will ask you “Do you want to start update?” and you should hit Volume Up for “Yes” (or Volume Down if you’ve chickened out)
  8. You can watch the thrilling process of the update or go do something else for about 5 minutes and when you get back you should see the message “Update Complete” at which point you just need to hit the Power button to reboot your phone and you should now be running your shiny new MR2 update.

If you have any questions before or after the update (or just want to share how awesome your phone is now) let us know in comments.
