Root XXUGNG8 Android 4.4.2 on Galaxy S4 LTE I9505 – CF-Root Method Details:

A few important things to note here. This CF-Auto-Root method tutorial is only for the Galaxy S4 GT-I9505 (Qualcomm Snapdragon Quad-Core CPU with LTE) and will NOT work with GT-I9500 (Exynos 5).

For those who are not sure about CF-Root, please read the following two paragraphs for a quick intro to the root package:

CF-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. A modified recovery and cache partition will be flashed, which will install (only) SuperSU, then clean-up the cache partition and re-flash the stock recovery.

NOTE: Using this root increases your flash counter. You should run Triangle Away after rooting to reset the counter. Note that if you want to run custom kernels or custom recoveries, your flash counter will be set to 1 at every boot. Either configure Triangle Away to reset the counter at every boot (Play version only) or only reset the counter when you need to go into warranty.

OFFICIAL FIRMWARE: You need to make sure your Galaxy S4 LTE I9505 is on the following firmware update before proceeding – Android 4.4.2 XXUGNG8 KitKat:

Backup and Other Important Tips

Done with the USB drivers? Perfect. The tutorial is on the next page, but first, please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps:

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:

Samsung users can also back up data using Samsung KIES. If you backup data manually, you get more options what to choose from and it is very easy to move data across Android devices from different manufacturers, i.e moving Samsung Galaxy Note backup data to HTC One X.

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.

A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and KitKat.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.

  • It’s a nice story, but the root part does not work at all. i9505XXUGNG8 is impossible to root, not with CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5 or Kingo Android Root. Maybe there is somebody who knows the real story

      • the root part does not work me also. i9505XXUGNG8 is impossible to root, not with CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5 .
        whenever i turn on ,it shows firmware upgrading issue..
        please provide some tips

        • Hi,
          Before updating my phone with this last release, I already had my phone rooted with towelroot (that doesn’t work with this last release), and I think I’ve used odin3 v3.09 (or odin3 v1.85, I’m not sure). Does it help ?

  • ODIN3.09 doesn’t have PDA but 3.07 does. Which option should you add the file to in 3.09?? Also, how long is ‘It can take some time’ for the ID:COM box to turn yellow?

    • Same issue here with Odin3 v3.09, the box goes pale green/greyish (never goes yellow, even after 15 minutes), it says 0:[COM4] in the box that probably is supposed to turn yellow, and in the message box it says ” Added!!” and there is no PDA thingy anywhere.
      Anyone got a tip how to actually do it in this 3.09 or a download link to a version that actually does what it says in the guide above?

  • did everything but it still dosent work..I think after it flashes supersu in recovery mode…it says returning to stock recovery then he restarts 2 times..and no root access at the final
