[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] KC6UFO:
Go back and follow the instructions exactly: Here they are so thanks them and i'll take one too:

thanks goes to travisw0204 and GhostTac for this

This is a step by step instruction guide for those having issues flashing this ROM using a MF9 Bootloader and wanting to keep their bootloader Knox free. This should only be attempted if you have tried the first install option multiple times and are following the instructions completely (unless you are already rooted) and are getting hung up at the Sprint Splash screen. Read these instructions carefully and all the way through BEFORE you do this processes and make sure you are not cutting corners.

1. You need to be on MF9 bootloader

2. You need to flash a stock MDC .tar file. Once downloaded you have to extract the .tar file using 7zipper or a program similar. I got mine from RWilco's site found here..

3. Once you have the stock .tar file you can then boot to download mode to prepare for Odin. Power down completely. Then press and hold Power + Vol down. You will see a warning page and then press vol up to get to download mode.*

4. Now plug your phone into your computer and open *Odin. I use 1.85 but some may use a later version. They all work.

5. Once connected to Odin the box in the middle to upper left should be yellow to let you know your phone is connected.*

6. Now click on PDA and find the .tar file for the stock rom that was obtained from rwilco's site. Hit start and let it run its course.*

7. Once Odin says Pass, the phone will reboot and you WILL get a yellow Sprint screen and nothing else. Don’t freak out. Press and hold the Power button and reboot the phone. Then press and hold power + vol up to boot into the stock recovery. From there do a factory reset and then the phone will boot up.*

8. Once fully booted you will have a small OTA update followed by the MF9 OTA update. This is the last OTA you should take.*

9. Once you go through those 2 updates you can then root using cf auto root through Odin (do the steps to get to download mode from above). Let it do its thing and the phone will reboot.*

10. Once you're booted up check to make sure you're rooted by looking for the super SU app in the app drawer.*

11. Now it's time for your custom recovery. Go back into download mode as mentioned above, plug the phone into the computer and open Odin once again to flash the CWM 6.0.4.4 recovery.*

12. Let the phone boot back up after the recovery flash.*

13. Now power down fully again and boot back into download mode.

14. Flash the mk2 modem found here (http://xdaforums.com/show....php?t=2338919) through Odin and boot back up.*

15. Go to Settings and About Device and make sure the baseband and version both match and end with mk2.

16. Now power down again and boot back into download mode. At this point it's time to flash the NAE modem to get you ready for Kit Kat. That modem also can be found at the above link for Unknown or in the OP in this thread.

17. Once you flash the modem through Odin follow Sacs instructions on how to flash the 4.4.2 rom.

It sounds like a lot but really isn't and it will assure you that you're starting with a clean slate and a Knox free bootloader.*

*You can use PDA for all your .tar files for this process in Odin or AP for later Odin programs.*

**This process will also work for those on MJA and MK2 bootloaders with Knox. You can follow the same steps but instead of going back to MDC you have to go to MJA and work up from there. There will only be one OTA update taken and that's from MJA to MK2. Once on MK2 follow Sacs instructions on how to flash the rom and you'll be good to go.

Thanks go out to Unknown and rwilco for their hard work and dedication

I bet you a buck you are not on the right bootloader. Check this using Device info which you can get from the app store. Then foolow the previous instructions i attached.
