[Galaxy S 4 Q&A, Help & Troubleshooting] Shelion:
I got my Samsung galaxy S4 GT-i9505 with build number I9505XXUEMK9.

After I got it, I noticed the LTE option is not available and after some research, I found out I have to edit one file with rooting.

So I went to try rooting with KingoRoot APK, and eventually got KNOX warning everywhere, I edited the file that hides the LTE network option and tried to remove root from the app but failed. I didn't really care because KNOX eventually stopped appearing and I can use LTE just fine.

I noticed an update for this phone around December 2015 which is Lollipop 5.0.1 from the internet and want to revert it back to official ROM.

At the moment, the phone's current status is "Custom".

My phone has been factory reset because of some reason and the LTE option is gone again. The status is still custom and KingoRoot SuperUser is still there.

I finally tried to root it for real this time by following this guide http://www.teamandroid.com/2013/11/30/root-xxuemk9-android-43-galaxy-s4-lte-i9505-firmware/

As I try it, the Odin give me FAIL status and I don't know what to do so I just put out the battery.

After trying to boot, the screen shows me "Firmware upgrade encountered an issue"

Then I tried to just flash everything to stock and upgrades to the lollipop instead so I went following this guide : http://xdaforums.com/showthread.php?t=2265477

I downloaded new Odin3 v3.10 and Latest lollipop 5.0.1 I9505XXUHOA7_OXAHOA7.zip from above link

I browsed BL, AP, CP, CSC without PIT file in odin and tried to flash it, FAIL occured

I tried again with PIT file, same FAIL

this is the screenshot
