The title says it all, people: those enterprising individuals over at XDA-Developers (where else?) have conjured up a permanent root for the EVO Shift. As this is the first method available, the process isn't quite so easy as it's become for other devices. Still, it's not too outrageously complicated, either.
ok download this file and extract it to the root of your sdcard
make sure you have adb properly setup on your computer before continuing
temp root using either visionary or z4root
open up command prompt and cd to your sdk platform-tools directory
then type adb shell then su
if you havent already u must press allow on your device to enable su perms
check the md5sum of both of the files to make sure they match
if these do not match do not continue redownload the files then check the md5's again
Flash the eng spl!!!
