Long Story As Short As Possible:
1-I Rooted my Sprint Galaxy S4 (with MF9) using Qbking77's You tube instructions (No Probs) !!
2-I dropped the Services.Odex, and Services.Jar into the systems/folder to replace the ones in there using root explorer to get the native hot spot working (It did NOT work) !!!
3-So I flashed via oden a "New" hot spot for rooted roms: "MDCHotspotMod-Odexed" onto the system, and now I am bricked...
I can boot into TWRP, BUT can't flash a rom to the system as it Fails.
I can flash the root "CF-Auto-Root-jfltespr-jfltespr-sphl720.tar" via oden which puts the stock recovery back onto the phone, BUT that wont't flash roms either.
SO, at a complete loss, I factory reset the device wiping everything, and it just boots to the Samsung Galaxy S4 Logo.
I downloaded the following: L720VPUAMDC_L720SPTAMDC_L720VPUAMDC_HOME.tar.md5 to try and flash back to stock in Oden, BUT, when I hit "Start" it doesn't do anything but say "The Parameter is incorrect"
This is the Stock MDC File, NOT the MF9 that my phone was currently on...
ANY SUGGESTIONS !!! Thanks guys.
Solved !!! Used MF9 Stock Tar file in Oden !!!
Glad you got it working!
Just in case you were wondering why it didn't work initially - you were on MF9, and you tried to flash the MDC hotspot mod.
And yes, flashing the stock MF9 in ODIN was the right step to fix this. If you now want to install the hotspot mod, make a nandroid backup, download the MF9 version and flash it in TWRP.

Any word on getting the hot spot feature working on the MF9 ?? Either Wifi Tether (specific settings), OR the regular built in Hot Spot?? Thanks... Also, I def know about the different software versions I.E. MDL, MDC, and MF9, the site said that particular file would take me back to stock & I would just have to OTA !!! Guess they were wrong, lol...:laugh: Anywho, thanks again, it's nice being able to get help when needed !!!

Yep - this is the one that I use as well.
@Ar3ohdee Just make sure that you get the correct version depending on your ROM - odex/deodex and MDC/MDL/MF9
BTW, if you were on stock MDC, you could update OTA to MDL and then to MF9 - that option would have worked too. But flashing the stock MF9 is quicker.

you may need to give us more info than that. what did you try flashing? were you already running a custom rom? mdc, mdl, mf9? did you try manually booting to recovery? (power + vol up)

Bricked on mk2
So I was on stock rooted mk2 with twrp recovery. Did a nand. Flashed kt kernel. Phone wouldn't get passed Samsung splash screen. Couldn't even boot into recovery. Took it to best buy. Tech, if you can call him that, said was bricked and I needed a replacement. Luckily just bought it so free replacement. Played dumb. Probably could have recovered if I Odin the stock firmware. My question is, what do you think caused the brick? Mk2 bootloader? Twrp? The kernel? I flashed plenty of roms and kernels on my s2 without problems. BTW flashed Hotspot mod with cwm and worked.
Okay, so long story short AT&T has cockblocked me from recovering my phone. I know, it has a locked bootloader. I get that. But let me start from the beginning. I was rooted (4.3), and my phone auto updated to KK, and essentially soft-bricked my phone. Well, I had to flash my 4.3 firmware (or so I thought) back onto my phone through Odin. The firmware turned out to be 4.2.2, and all of it failed to flash except the modem. It still started up fine, but I couldn't connect to wifi. It wasn't even an option to turn it on. Turns out I was still on 4.3, with a baseband of MF3, and a build number ending in MK2. I didn't know how to fix this, so I've kinda flashed it with all sorts of things hoping it would help. I've tried all variations of 4.2.2 seeing if I can get things to be all either MF3 or MK2, so far no luck. Well today I tried to flash it with MK2 firmware, and it went like 95% through, and failed. Restarted, and it says "System software not authorized by AT&T has been found on your phone."
This is because of the bootloader, I get it.
The 4.2.2 modem is the only thing to successfully flash. Any clues why? Any clues onto how to recover my phone at all? You guys are true geniuses, please help.
Also, my device status is still on "custom" with the unlocked icon.
Any help would be tremendous, as I feel like a complete and utter moron. I have both Windows 7 & Linux Mint my use, so suggest anything. Please. I'm begging you.
I had the same problem i soft bricked my phone by installing MF3 and i was already on MK2. Just download MK2 http://forum.xda-developers.com/showthread.php?t=2621279 flash first only AP_I337UCUEMK2_1921628_REV06_user_low_ship_MULTI_CERT.tar.md5 by using PDA on oDin see if that fixes your problem.

Well, I feel stupid, I never had the phone in download mode so that is the reason it failed. This is what hapopens when yourn addicted to phones and go thru different ones every coupkle of months. I managed to fllash and downgrade but lost both data and Wifi. I searched but could not figure out why I could not get data and wifi to work on MK2.I rooted and all but could not get data or Wifi to work. So, I Odined back to NB1 and have both data and wifi working. I'm not sure why I lost it. I really want to be able to get MK2 back up and running but I'm at a loss. Could use some help with this.

Do a data factory reset from recovery after you flah thru Odin, it should get you out of the bootloop. I had the same thing and after I did the reset it booted ok. Only issues is that I loast data and wifi on MK2.
i have a sgh-i337 that i was going to downgrade and root via the saferoot method on here. i first downgraded the modem so i would have access to the hidden menu for unlocking purpose, after that the phone wouldnt accept any other flashing. i tried the PIT, stock firmware, stock rom all of these will fail in odin. i have tried to do a emergency firmware restore in kies which also fails.
please tell me theres some option im missing somewhere
You can't down grade firmware on the i337. Try flashing the same firmware version as you had before attempting to down grade in Odin

i was on NB1, sorry about the lack of info there.
i finally got it sorted out... well almost.
it turns out that flashing the modem again allowed me to get the phone back into working condition, after which i was able to downgrade to MK2
this worked fine and dandy with one issue remaining, i have no sound what so ever. no notification, music, video, nothing. wont even play music for that matter, says it cant open this type of file "mp3" even pandora wont play.
thanks for the replies.
flashing a stock NB1 fixed the sound issue, guess i will have to wait for someone to root till i mess with it again.
and for anyone interested the unlock method via hidden menu worked for me doing that downgrade/upgrade. im on tmobile

You can't use the ODIN modem files. You can get root on NB1. Follow the guide specifically, then flash the modems from RockRatt's thread through Safestrap.
I recently bit off more than I could chew with my S4 (I337). I had 4.4.2 KitKat on it and wanted to root it to add teathering. I decided thought there was no root for 4.4.2 so I thought I would try downgrading to 4.3 then root. This seemed best because I didn't like the way the SD card is handled in 4.4.2 and some of my apps (like ftp server) have stopped working.
When I got the phone back up from flashing with Odin it says it has version 4.3. My WiFi will not turn on. If I slide the switch to on it slides right back to off and the phone tells me that an operation was block (can't remember the full verbage. I have installed and attempted to install many things on my phone. I have used recovery mode / Odin3 and Kies (Kies doesn't allow much).
At this point I just would like to get my phone back to 4.4.2 with the WiFi working. Then I can restore my backup and be back to square one with a lesson learned.
I have an I337 that currently thinks it has version 4.3 on it. The baseband version is I337UCUFNC1 currently. The build number is JSS15J.I337UCUEMK2.
If anyone can help I would greatly appreciate it. I have read and tried many things over a two day period and finally decided to ask for help.
Had this issue before on my Bell Canada S4, but don't recall exact way to fix it.
Think the solution was to find an older (might be newer) stock. I think I used a different version like the Telus Canada version as well and it ended up working. Then you update through kies after.

Wifi does not work because of the modem/kernel mismatch, i.e. MDB modem and MK2 kernel. Not sure what your goal was when you began flashing your phone but since you fortunately did not flash teh MK2 bootloader you are still able to locate the MDB full odin tar and flash back to stock which will resolve your issue.

If you don't care about losing your MDB unlocked bootloader you can get to the latest kitkat firmware by flashing the NB1 full odin tar from here:
http://forum.xda-developers.com/showthread.php?t=2674223, then once flashing is complete go to settings/more/about phone/software update then take the ota update to NC1 which is the latest kitkat version for our phone.
But what I would do is keep your unlocked MDB bootloader and since you already flashed the MK2 AP file you can get your phone running well again by flashing the MK2 modem: https://mega.co.nz/#!pwESna5I!YK7EKG37xXIG1ReB-Z-mfSMoXNkXQ9t2EdMK9ofgJKg
From there, there are still a number of options available to get to kitkat which I won't get into.

Do you already fix it??? cause i have the same problem
Same question, different thread!
Not even an hour ago did I answer the same question in a different thread: How do I get WiFi working on my S4?
Well here you go.
My original answer: http://forum.xda-developers.com/gal...-4-4-2-nb1-t2850878/post54978150#post54978150
The problem is, in order to get WiFi working, you need to install the NB1 modules, but to do that, you need to install Safestrap. However, you can not install Safestrap because the app keeps closing on you. There is a simple fix to this, which I will explain later. For now, just read this WHOLE post BEFORE you do anything, and keep in mind that I am NOT held liable if you mess up your phone. Use this at your own risk.
1.) Root your phone
If you're already rooted with something like SuperSU or Superuser, skip this. If not, read ahead. Download and install the Towelroot APK file attached to this post, open it, and click 'make it ra1n'. If your phone didn't reboot, now you have root (they need to trademark that). Now, down below, I also included the APK for SuperSU. Download and install it. Now open it. When you open it, let it install the 'Normal' way, not via the 'TWRP/CWM' way. Also, when it asks you to disable KNOX, say yes, wait a couple of minutes (it will still be loading) and reboot your phone. Open up SuperSU again, click 'Yes' to disable KNOX again, and now you have a good base to start from.
2.) Install Safestrap AFTER fixing the error
The error your are getting is easily fixed. Go to the Play Store and install 'SELinux Mode Changer'. Open it, grant it root access, and change the mode to 'Permissive'. Now, open up Safestrap again (you mentioned you already installed it), and it shouldn't force close. Click 'Install', and if the 'Reboot to Recovery' option below is not grayed out after that then it worked.
3.) Download and install the NB1 modules
On your phone, download the included NB1 modules ZIP file I attached for you, and once that is done you need to reboot. After the Galaxy S4 logo, you'll see a screen that says 'SAFESTRAP: DISABLED' and there will be a little robot. TIP: To enter Safestrap, press the menu button (physical, hardware key) under 'Recovery' at that screen. To continue to Android, press the back key (again, physical) under the 'System' tab. For now, press the menu button under 'Recovery'. Now, click 'Install' which should be in red, click 'Add zips', and navigate to your Downloads folder. Now click on the NB1 modules ZIP you just downloaded. Swipe to install, and reboot. This time, hit the back key under 'System'.
All done!
Now, Android should (and will) boot up, and you'll have working WiFi! If, for some odd reason, you don't have WiFi- do NOT panic! Just search around for the MF3 modules and flash those! All is good, all is good. A lot of this guide was taken from my post about my personal method of SIM unlocking the AT&T Galaxy S4 without the dialer codes or an AT&T SIM. It was just modified a little to work for you.
Remember, hit thanks!
