A few days ago we told you that the Galaxy S4 (Exynos 5 Octa version) has been rooted ahead of its launch, but it looks like that particular root procedure wasn’t actually a working one.
xda Elite Recognized Developer Chainfire managed to root the Qualcomm Snapdragon 600-based Galaxy S4 version (GT-I9505) and the method has apparently been tested successfully. While his root should work on the Exynos 5 Octa version (GT-I9500) as well, it seems there are issues with rooting this particular Galaxy S4 flavor at this time.
The xda-developers blog further explains that the previous Galaxy S4 root method was not actually tested on the handset. While in the past this wouldn’t have been a problem for previous Samsung devices, the Galaxy S4 comes with added security on board – Samsung’s Knox security system for Enterprise customers – that prevent that particular root method from working as expected:
In many cases, like previous versions of the Galaxy series, that is OK [rooting the device without actually testing it] because the way to root Samsung devices has been the same via repacking Samsung’s firmware package with su and then flashing via ODIN. While that old way worked, it doesn’t work on the new S4 as XDA Recognized Developer Odia proved in a thread similar to the original “root” thread.
[…] XDA Elite Recognized Developer Chainfire began toying with the Qualcomm version of the Galaxy S 4 (GT-I9505) back in early March, and immediately began to have issues with the “tried and true” process for rooting previous Galaxy devices. He noticed that while you could “inject” the su binary into the firmware, the device would immediately reboot when that same binary was executed.
Instructions for rooting the Galaxy S4 GT-I9505 are available at the Source link below, although, like always with deciding to root a device, we’ll remind you that it’s entirely up to you to go for such procedures, and it will be your responsibility alone for whatever happens during and after the process.
The Galaxy S4 is not even out yet anyway, so you’ll have to wait a while until it becomes available in stores to try to root it. As Chainfire points out on Google+, it’s not known what firmware the Galaxy S4 versions will run at launch, so it’s not clear whether this root method will still work once the handset hits stores.
