It seems to be a constant struggle with keeping my Samsung Galaxy S4 rooted with a custom boot loader… every OTA it seems they roll out a patch or overwrite customizations. I think there’s something to do with the boot loader being locked in a way we can’t put custom ROMS like CyanogenMod on? Not entirely sure…
Well, the only real thing I really want my rooted S4 to do is have WiFi and USB tethering… When I’m on the run, I absolutely love having my Nexus 7 or laptop handy in case of a sudden coffee shop has horrible WiFi…
First and foremost you will need to root your AT&T Galaxy S4, below is a link to how to.

Secondly, you will need to place Safestrap onto your phone and flash the custom tether files.

When I have time I will simplify/consolidate both the links as a mirror in case of emergency.
