Nearly a couple weeks ago, the Jelly Bean (4.1.1) update to the Evo 4G LTE
XL BBQ began to roll out. By now, we think it's safe to say that most or all of you have it. If you don't, however, or if you've already updated, flashed another ROM, and want to get back to stock, then maybe I can interest you in a nice RUU?
As a side note, if you're HTCDev unlocked, you'll need to relock your handset or you'll get an error while trying to run the .exe. More information on relocking the bootloader can be found here.
