AT&T, Sprint and T-Mobile versions can now be rooted with a simple tool
Well that certainly didn't take long, did it? With only AT&T's variant shipping to pre-order buyers, Sprint's launch mere hours away and T-Mobile's launch pushed back, we now have a root tool available for these Qualcomm-based Galaxy S4's. The tool, created by djrbliss over at XDA, which was originally made for Motorola devices seems to be working for these Galaxy S4 models as well. Many users in that forum thread are reporting that their devices are being successfully rooted with the tool, which simply takes a few steps of setup and running of a program to root the device.
We'd caution against jumping right into rooting at this point if you're unsure of what to do with it on your new device. As the poster points out, with no custom recoveries or stock firmware images available for these devices you may be in for a world of hurt if you make the wrong move with your newly rooted device. As always, proceed with caution here.
