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
Galaxy S4 - i337m - Android 4.3
Okay, so here's my problem.
Today in the morning after I woke up, I checked my phone and it said it had downloaded a software update. It was just a complimentary update for 4.3, it said bug fixing, etc. in details. I clicked accept and the installation started.
After this, all crap started to happen.
The Wi-Fi NEVER worked again, everytime I clicked the Wi-Fi widget in the notification bar, it turned green and immediately switched back to gray. It also didn't work when trying to turn Wi-FI on from the settings menu.
I tried everything, the battery pulling, the thing of disabling the Wi-Fi energy save, and nothing worked. It all pointed to a factory reset.
So I did all my backups (My S4 was rooted), and finally made the factory reset.
After this finished, I did all the starting configuration of the S4 (like when it was brand-new). Then, I tried to turn on Wi-Fi.
Surprise, surprise. DIDN'T WORK.
I'm so desperate right now, I don't know what to do.
I'm currently downloading 4.4.2 to flash it via Odin, and see if this works.
Any help, please?
Flashing the 4.4.2 ROM you're downloading now should definitely fix the problem. I know that in some instances, us I9505 owners have to flash a stock ROM twice through Odin before the modem will function. It sounds like your software update broke the modem in this fashion, which is why the ROM install you're planning should fix it. Be aware however that installing KitKat will give you Knox if you don't already have it.

Fine. Right at this moment I'm installing 4.4.2
Hope this works.
I'll tell you what happens.
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?
Anyways as my title says, i don't have wifi. I had first rooted my phone, but then I unrooted my phone by flashing some unrooted os on the samsung which caused two problems. My wifi and mobile data didn't work at all, but after I took it to a repair shop they fixed the mobile data and got it working again and rooted my phone but not the wifi part. According to the person that tried to fix my phone, the current android os, 4.3 - jellybean, that i flashed via odin is preventing the wifi from working. I don't really know whats wrong with the phone but can anyone help me? Also by baseband version is 1337UCUFNJ4 and the build number is JSS15.1337UCUEMK2. Should i try to find a ROM that matches my baseband version and flash it via odin? Thank you in advance!
P.S. This is my first thread, so please tell me if i violated any rules.

im having the same problem and i think we both have knox stupid security back on the phone that's blocking the wlan to start from bad permission or encryption
so personally yeah i will install back the original firmware (before 4.3) from factory reset (or via odin if i have to force it) then im gonna re-root the phone
having back permission ill remove knox (probly with titanium) lock and box bs from base firmware and probly remove root right
then im guessing ill have my internet back now will i go full rom again or basic function thats a good question
so many freaking remote exploit lately
ill let you know if that fix it
I also just found this
om22 said:
1. untick "Auto reboot" in odin
2. flash the stock rom again
3. reboot your phone to download mode again (by holding the power and vol down button for 10 sec)
4. flash the stock rom a second time with auto reboot ticked
This will fix your problem.

seems that clicking auto reboot might be the cause
so would i install the I337_NJ4_Stock_Kernel.tar.md5 file following that method or would i have to find another firmware/rom/(i don't know what to call this) unrooted

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.
