Rooting is one of the best things about Android. It is a bliss that lets us satiate our appetite for customization and tweaking the device. However, sometimes our OEMs and service providers try to put a check on the very soul of Android by putting a check so that users might not be able to root their devices. That is why there is always a cold war going on between our developers and service provider. Fortunately, in most cases the great minds of Android development community come out with victorious smile.
The latest mischief has been made by AT&T who appears to be following Verizon’s path. An OTA update with baseband version UCUAMF3 for SGH-I337 rolled out the last month brought a security patch, making all existent root methods ineffectual. Moreover, the users of the AT&T Samsung Galaxy S4 with MF3 version are unable to downgrade to a lower version.
However, the users of this device can now take a sigh of relief because XDA member Jortex has released a working root exploit. So, if you have updated your phone to build number JDQ39.I337UCUAMF3, you will now be able to achieve root access. Though Jortex’s method is not so easy as the Motochopper way, it is not very difficult to perform too.
Now here are the simple steps to get root on AT&T Galaxy S4 SGH-I337 on UCUAMF3
cd /mnt/extSdCard ./pwn ./script.sh
If everything goes well, you will have root privilege on your AT&T Galaxy S4 SGH-I337. Open app drawer and look for the SuperSU app there. To verify successful root, install Root Checker app from the market:
