How to: One-click root for AT&T Galaxy Mega with MK2 software update

AT&T Galaxy Mega (SGH-I527) has been received a minor software update last month with baseband I527UCUAMK2 via OTA. We say a minor update, since there’s no OS upgrades in other words still loaded with Android 4.2.2 Jelly Bean. Fortunately, superuser access still can be obtained on this smartphone, so no reason for rooted users to overlooked it.

Until now only one tool that has been successfully regained root on the AT&T Galaxy Mega running MK2 software version. This tool in the past also successfully achieves root on the older software version before MK2 update released, so we are not surprised if it also works on the most recent software update.


For those who do not know the MK2, it brings Samsung Galaxy Gear software support as a key enhancement, while others such as improved camera, add Google security patches, updated third-party apps, etc. I’m sure many of you were a little disappointed not to get the Android OS upgrades just like the Galaxy S4 or Note II, however, a minor update is better than nothing.


  1. Enable USB Debugging on our phone, it’s required.
  2. Get Galaxy Mega drivers for Windows computer, although the tool can install the required drivers automatically, it’s better to do it manually.
  3. Download Kingo Android Root tool for Windows, this is a universal one-click root app that has been proven to provide root for dozens of Android devices.

    Doesn’t work on Samsung Mega SGH-I527 running Android 4.4.2
    NEVER makes a connection. Was told by KINGO it doesn’t work on a Mega even though advertised like this example.

      Hi Rick,
      This guide is for Samsung Galaxy Mega running Android Jelly Bean. You’re right, doesn’t work with the latest KitKat update.

    I tried and it does not work. I see all over the place online that people have claimed this works, even on KitKat. I however am unsuccessful. Very frustrating. I paid good money and this device is mine, I wanna do to it what I choose and not be limited by the stupid KNOX on the phone.

    When I bought my phone (SAMSUNG-SGH-l527★Android version: 4.2.2) they said it would be rooted. They used

    Kingo SuperUser Version :

    to root it. It worked fine for about a year. I did a factory reset now some charging page screen pops up when I charge it.

    This page screen is extremely annoying. It blocks me from shaking my alarm clock off in the morning.

    There is a little gear in the top right corner but the charging screen, when it is clicked the screen goes blank.

    How do I get rid of the charging screen?
