HTC said they wanted to get the EVO 4G LTE on Sprint updated to Android 4.3 by mid-February, and they've hit that goal. HTC's VP Martin Fichter posted a link on his Twitter feed to the RUU for Android 4.3 for the EVO 4G LTE.
HTC RUU's are update utilities that let users manually update a device to a certain software version. In this case, the RUU updates the EVO to Android 4.3, with one catch; it has to wipe your phone to install.
Apparently, HTC wanted to push an OTA update to the device, but due to memory restrictions on the EVO, they had to go with an RUU, evidenced by the mandatory storage wipe. Still, that's a small price to pay for getting Android 4.3 and Sense 5. If you want to manually update your device, grab the download link below, connect your phone to your computer through USB, then start the EXE and follow the instructions. Be sure you've got everything backed up before you proceed, too.
