Looks like this holiday season is a busy day for Samsung since almost all its devices get a software update including the T-Mobile Galaxy S4 (SGH-M919) that has been getting a major OS upgrade to Android 4.3 Jelly Bean with build number M919UVUEMK2. This is very good news for users even though it does not bring the latest version of the Android OS.

As always the rooted users will curious if superuser privileges can be obtained easily after taking the update, but don’t to be concerned, it is possible to regain root on the T-Mobile Galaxy S4 after MK2 update with the method we have used previously.


The M919UVUEMK2 update has been approved by T-Mobile to be released last month, we can easily get the update via OTA or manually through Samsung KIES. In addition to the last version of Jelly Bean, it brings several new features that almost all Samsung devices running Android 4.3 also have it: Samsung Galaxy Gear support and KNOX.

As talked over, it also comes with locked bootloader and Knox features, which limits us to modify our device’s software, however, here’s the T-Mobile Galaxy S4 root on the MK2 update with Auto CF-root.


  1. If this is the first time you connecting your smartphone to the computer, then you need SGS 4 device drivers.

  3. Download CF-Auto root, scroll down and pick the appropriate file for your phone’s specific model number (SGH-M919).
