When I bought my phone I was on MF9 firmware stock. I rooted it , then tried to do the system hotspot mod. i ended up bricking the phone. The only way I could unbrick the phone at that time was to flash to MDC, which the hotspod mod was working on. Now ive been trying to flash newer custom roms,(because im still on ancient MDC), and I can never get it to work. Do I have to upgrade in order ? Ex. MDC to MDL to MF9 and so on ? Does my hotspot system file mods have something to do with it ? I really wannt try these new ROMS , but it just never works. Any help would be greatly appreciated.
I would like to know this as well. I'm stuck on MDC (i think thats the first firmware?) and I would like to know the best upgrade path in order to get the latest modem, ect.
I'm on mf9 with the hot spot working. Tried to go to the mdk modem and software, soft bricked twice. Gave up and went back to mf9. If it ain't broke, don't fix it lol.

Hello everyone, i'm a new member. I apologize if my english is not good enough.
After been driven insane by one pre-installed app from my Operator (Claro Peru) i decided that it was time to root my device to get rid from that pest. I'm a noob, so i started to investigate about the safest methods to not damage my phone. My Device's model is SGH I337m.
The plan was to update the FW from JB 4.3 that came with my phone to 4.4.2 and then proceed to root. I downloaded the Canadian 4.4.2 FW with build version I337MVLUFNC1 and installed manually with Odin. After the phone rebooted, my S4 was upgraded with 4.4.2 but Samsumg keyboard was going insane, so i went to the apps and solved that cleaning the cache/data. Then i noticed that the Wifi wasn't connected, i tried to turn it on, but then a message with a shield appeared saying that my device security stopped the operation. Beliving it was only a problem with KNOX, i installed autoroot (CF-Auto-Root-jfltecan-jfltevl-sghi337m) with Odin, open SuperSU and stopped it from working, but the Wifi still wouldn't connect.
So the first thing that crossed my mind was to unroot and do a factory reset, didn't work. The FW still was 4.4.2, so i´ve been searching solutions with this FW because i've read some cases of devices that stopped working completely after trying to do a downgrade. so i don't want to go to that route for now.
After a couple hours of search, some solutions i found on the forum were:
- Install Faux123 Kernel (Found on Youtube, this would be the thread i think http://forum.xda-developers.com/showthread.php?t=2273437http://forum.xda-developers.com/showthread.php?t=2273437
- Flash a modem for i337m
- Safestrap recovery and bypasslkm.zip
- Downgrade
I haven't tried any of this methods because i dont want to get into a deeper trouble. In the first solution i'm not sure what to do because this is the files the author recommends for canadian models (i337m), but when i enter here http://faux.romhost.me/jflteatt/jb42/http://faux.romhost.me/jflteatt/jb42/ only jflteatt appears, and that would be i337 model, isn't it? I thought that installing it may cause more troubles, so i didn't do it.
For the flashing modem method, i'm not really sure if installing a modem from another country would get me in trouble, so again i didn't proceed.
I found the Safestrap and recovery method on a downgrade thread for the i337, so again, didn't do it.
So, is there a way to get one of this methods working on i337m to get wifi working again, or is there any other better method to get back wifi.
I would really appreciate any help you can give me guys.

ok so you have the i337m canadian version... making anything related to safestrap and the att i337 irrelevant, completely different methods so don't get them confused lol
you were updating from stock 4.3 right? your best bet is to factiry reset and reflash stock fw for 4.4.2 before you brick your device... kitkat is very different from 4.3, maybe read up on it a bit too...
for ex, the "message with a shield appeared saying that my device security stopped the operation" isn't related to needing to root, it's an option under security settings.
to enable superuser on kitkat you need to enable developer options, then enable superuser. I prefer supersu so manually install that from play store afterwards. I recommend checking and/or enabling this as soon as the phone completes booting up after flashing.
also I think there's a known issue w/ 4.4.2 and wifi not turning on until after 2nd boot completed if I rememebr correctly, been using 4.4.4 for awhile now though so could be wrong...
good luck and check out the help section :angel:
Hi everyone, long time reader, first time poster.
First of all, i want to let you all know how i appreciate all the hard work you guys do on here. i was able to get all the info i needed to get my ATT n7105 back to stock after running CM 10.2 for the last year on it.
Back on topic...i have an S4 i337 running 4.3 MK2. when i first flashed it, for the longest time i couldnt figure out why i couldnt get signal or wifi, and found out needed to flash the MK2 modem firmware also (thanks for the info on that also). now the issue i am having is that now the phone has no sound at all, tried playing music, recieving a call (which makes the phone go total bonkers too), or even the beep it makes when adjusting the volume. I have tried searching for info on sound issues, but that was one thing i was unsuccessful with.
when i first got the phone, it had 4.2.2 (not sure of the firmware) and wanted to unlock it to use any carrier rather than just ATT. the only way of unlocking it, rather than getting an unlock code, was to go into service mode, and navigate through some menus, but i read that with 4.2.2, i could not, so i done an /ota update, which brought me straight to 4.4.3. after the unpdate, tried doing the service mode again, and had no luck, so tried downgrading to 43].3, than went to hell trying to get it working, untill coming across these forums, and got it working again with 4.3 MK2, but as mentioned, with no sound.
Any advice on what to try?
Thanks in advance.

You don't have sound or the ability to call because your bootloader and non-hlos don't match. You can get sound by flashing the NB1 or NC1 modems(including non-hlos.bin) but that will break your wifi which can be fixed by using bypasslkm.
Sure, ill give that a try.
What if i were to update it to 4.4.3? any certain modems required there?

Whenever i tried flashing NB1 or NC1, i get an error saying "signature verification failed, then later on give an error "unknown path \sdcard1" after wiping data, then reboots. and when the phone rebooted, it goes through the first time setup after a wipe, and then checking the modem, and its still NK2.
I really would like to get it to the current version.

Awesome! thank you very much
With the instructions you provided, i was able to get my i337 in working order.
your assistance is greatly apreciated
I was rooted on 4.2.2 with Rogers but wanted to update to 4.4.2 and didnt really use the root anyway. So i installed back the stock rom and resetted to factory. But now wifi wont turn on at all. I ran the softaware update and im still on 4.2.2 and it says I have the latest version available but i know rogers released 4.4.2 in march 2014...
Anyway, which way should i go to get everything working again?
Thanks
I don't know if anyone has explained why this happens, but sometimes the modem firmware doesn't completely "take", leaving parts not working correctly. Reflashing the modem usually corrects this. In your case, where you want to upgrade to the latest firmware, you should download it from sammobile.com and flash it through Odin. Not only will you not have to worry about a software update, but installing the updated ROM through Odin should correct your WiFi issue as a new modem will be flashed with the firmware.
downloading now, i'll report back
fixed thanks a lot
I rooted to 4.4.2 and it went fine- then I realized I had lost wi-fi.
I have tried to restore and tried using odin and zip files to install a stock rom after I found a similar problem with link on
Sprint forums saying it will fix the ""button won't stay on" but the fix only works if the device is in stock rom.
answer on Sprint forum says baseband version was mk2 needs to be nae.
Return the phone to stock, run the fix for the wi-fi and then re-root.
I have downloaded and ran several roms that say they are stock- I've factory reset, cleared cache, no matter what I do,
I end up with a rooted device in 4.4.2 and no wi-fi. If I could just get the wi-fi back I would take it at this point
This was just a little quick upgrade that turned bad and long
The Sprint forum had a link to get it to nae, but wont work if rooted., so need to put the phone back to stock- run the patch and then can upgrade to kit kat again
TLDR: I cannot get my Sprint s4 back to any version that isn't rooted. I have tried several (lots) of roms that say" stock-unrooted" rom,
Never goes back to stock- stays rooted without wifi-
Ran a rom VPUAMDC_L720SPTAMDC_SPR but when I install I get msge "ifooter is wring signature invalid" - and it fails.
reformatted the sd card, tried different roms and get some message and it stays rooted and no wifi.
TLDR: need to get stock rom so I can get back wi-fi and then root the whole thing. as 4.4.2 Or 4 , if it exists)
Any options and any ideas as to where or what to do?
EDIT: for clarity cause I am not making much sense at this point
Thanks
Heh... a TL;DR for a TL;DR... the internet is becoming one crazy place.

Maybe a dumb question, but why not just unroot first, then?
I received a new phone since I broke my old GS4 (I337). It was on AT&T 4.2.2 and I rooted it using motochopper. It was fine. It automatically updated while I was asleep to 4.4.2. I had rooted my old GS4 on the same update. So I figured I'll just root it again. So I used the method where I flash the NC1 kernel, use towel root, then flash NJ4 back. Now my WiFi will not turn on, but I do have root access. Also, a message saying "Unauthorized actions have been detected" and it tells me to restart to undo these changes. I don't want to do it in fear of bricking my device. I'm really scared now and I desperately need to fix this. I just want to go back to complete stock 4.4.2. I've tried reflashing the NJ4 file twice and WiFi will still not turn on. I've attached pictures of the notice and my device info. Please help. I cannot brick this device. I will answer to any questions as fast as possible. At the moment, I am debating whether or not to flash this because I am unsure if it will be compatible.

Bricking is almost impossible. So stop stressing out. You are in the wrong forum.
http://forum.xda-developers.com/galaxy-s4-att
Usually you have a wrong modem flashed or something with that problem. Stop stressing out and take your time to find the solution. You will not brick it.
