N910KKTU1BOB5_N910KKTC1BOB5_KTC.zip

Stock firmware for Android 5.0.1 for the Samsung Galaxy Note 4 South Korean Version. This is for the SM-N910K, the South Korean version, and will not work on other N910 models.

The zip file, N910KKTU1BOB5_N910KKTC1BOB5_KTC.zip, contains exactly one file inside it: N910KKTU1BOB5_N910KKTC1BOB5_N910KKTU0BOA7_HOME.tar.md5. That file is 3.0 GB in size.

To install the firmware, you probably want to use Odin. If you don't know what this means, or if you're running stock firmware and haven't rooted your phone or done anything special, it may be easier to get the firmware update through your provider. If that is impossible or takes too long, this file is what you want.

Installing this firmware on a rooted phone will un-root the phone. It is reported that you can root the phone again using CF Auto Root just as you may have done before.
