After downloading/installing a USPS Mobile app (go figure) yesterday, my phone totally froze and would no longer boot up. Phone is all stock and never rooted. Very strange. Anyhow, factory resets were not working to properly restore the phone, so I was left to re-flash the original software.
This is the link I found for the ORIGINAL software that shipped with the phone:
[RUU] HTC Incredible 2 Signed RUUs (PG32IMG.zip) - Droid Incredible 2 / S - RootzWiki Note that if your phone is already upgraded to Gingerbread, flashing Froyo software will not work. Just go ahead with the latest version and you should be set!
Better instructions on how to do the actual flashing can be found here:
[RADIO] HTC Incredible 2 Radios [PG32IMG.zip] (Updated: 20 Sept 2011) - Droid Incredible 2 / S - RootzWiki It is wise to perform the MD5SUM check to ensure your download didn't get corrupted in any way.
After a couple hours my phone is totally restored and now running smoother and faster than ever!
