Root S4 mini SGH-i257M A year or so ago I was looking into rooting my S4 mini SGH-i257M. This is the Canadian version, Android 4.4.2 from Rogers. At the time there was no reliable method available, and no hope of there being one in the near future. I am wondering if anyone has found a reliable root procedure for this phone since then.

Baseband version i257MVLUBNG2
Kernal Version 3.4.0-2254622
Build number KOT49H.i257MVLUBNG2
The answer is yes, a simple reliable root procedure has been found for this phone. It is CF-Auto-Root by Chainfire. Here is a quote from Chainfire's initial post outlining the philosophy of this procedure ...

CF-Auto-Root is the root for "rooting beginners" and those who want to keep as close to stock as possible. CF-Root is meant to be used in combination with stock Samsung firmwares, and be the quickest and easiest way for your first root. In essence, it does nothing but install and enable SuperSU on your system, so apps can gain root access.

Here is the link to the actual procedure ...

Note that the procedure is for Build number KOT49H.i257MVLUBNG1 but i took a bit of a risk with my phone which has Build number KOT49H.i257MVLUBNG2 and it works flawlessly.
