Reflash the NB1 tar file in ODIN and see if it works then. You can find it in the general section, either search for the thread or find it in the [INDEX] thread.

started working for 5 hours then returned same issue...
I used Odin to root it using Nc1 Then finished with J4 ...

im guessing this must be a problem many are facing. a friend of mine gave me a an S4 logic board i337m variant and it has the same issue i have tried everything from flashing new roms flashing stock frimwares tried different kernels modems nothing seems to work. i second this post to see if we can find a solution. my phone is a I337m and have flashed GOLDENEYE to get the lollipop experience a month before the official Lollipop came out for the canadien variants and i have not had any problems i was wondering if i made a backup with trwp and see if this might fix this problems and if it does i can upload my exact backup to help other. but i was wondering if a dev can help me out and see if this could be a possible solution.

In the same boat aswell
I gave my phone to someone to update it to lollipop GPE about 2 months ago.... wifi would work but my data connection would cut out the minute the screen shut off.... after contemplating going back to the guy.... i downgraded to hyperdrive kitkat rom witch gave me better connectivity but no wifi... I ve been living with that for up until now until I decided enough is enough and flashed the stock lollipop rom yesterday. still no wifi. whats even more frustrating is I cant find the file path thats being mentioned so commonly as the solution.... and yes I am rooted. Also wifi was working no problem before I updated..

Well last night I went from 4.4.4 back to 4.4.2 to see if thus would solve the wifi and blue tooth head ache. It all started working just fine and did all the way up till tonight then back to not working. I then resulted to cleaning the Wifi prongs on the phone and it worked again for few hours. Now the weird thing happens I put it back into the phone case and just from snapping it in it stop working AGAIN. I restarted the phone once taken out of the case and it was working so I think I'm at a conclusion it's a mechanical issue not software. Maybe the wifi circuit us faulty
I've had lots if Galaxy and worked on a few friends but this wifi and blue tooth crap us unbearable.

My Bluetooth is fine. My wifi broke after downgrading to kit kat so I know it works It just seems the wifi files are corrupted or missing. I'm sure it's simple I'm just not savvy enough to implement it

[Q] Telus SG-I337M / I337MVLUAMG1 Baseband With Kangabean GE Romm Issues

This is my 1st post ever because every question I've ever needed answered I've been able to find.Unfortunately I cannot find the answer to this problem. Since my Post count is below 10 I cant post the question in Kangabeans thread.
This is the ROM I am using
I rooted and flashed my phone 4 days ago and ever since then my wifi or mobile connection never go above 2 bars. Everything works except data cuts in and out fairly often which never happened before while i was using stock. I can sometimes get LTE but it mostly just says H and is really slow. I live right in the middle of downtown Edmonton and always had an LTE connection before so I'm pretty sure it is an issue with my phone and the ROM. I can also be standing right next to my wireless router and i only have 2 bars showing up for wifi.
I know some people had mentioned similar problems in the Kangabean thread with poor LTE connections but almost all say it is working good which leads me to believe its something I've done. My initial thought to fix the issue was to flash a new modem, specifically this one modem_CWM_I337MVLUAMDJ.zip{4/22/2013}(Canada) from this thread because everyone that was saying their LTE and WIFI were working appeared to be on an MDJ baseband. I tried flashing the modem and nonhlos through Odin but it failed with odin saying: Failed, Receive response from LOKE. I figured my best course of action was to try and reflash the MG1 Baseband but again i recived the Failed, Receive response from LOKE. Thinking i screwed something up i decided to try and boot up my phone and sure enough i was stuck in a bootloop. Luckily all I had to do was load up recover and wipe the cache partion.
Everything is back as it was before i tried flashing the modems, even the poor connection to WIFI and Data.
Does anyone have any idea as to how I can fix this or what I did wrong that caused Odin to fail flashing??
Pretty sure I just found my answer for why I cant flash the modem. Im pretty sure MG1 is newer than MF3 (correct??) and if your on MF3 Odin wont work
I was doing some thinking..... I have mobile odin pro Can I try flashing the MDJ or MF3 Modem and nonhlos files with it or will it too end up failing??

Wow hold on! Do you have telus sgh-i337m s4? If so then you don't need anything to do with mf3. Only att and sprint have lockedbootloader. If your baseband is MDB or MDJ then you don't need Loki and mf3 kernel, in fact you'll brick your phone if flash mf3 kernel on any s4 brought in Canada.
You shouldn't be going anywhere near MF3 on your i337m. MG1 or MDJ only for us Canadians
Thanks guys I wasnt sure If I could flash those without any problems so I was waiting for someone to reply to this thread before i tried going that route to fix my connectivity issue again.
Sorry guys,
I am a Canadian with a 1337m MDJ S4 running CM 10.2
I just wanted to double check that I am bound to ROMS made for MDJ. Cannot I not update to MDL?
There are a number of TW Roms that I would like to try to get my camera and multiwindow options back Like :
FoxHound GearEngine 1.3 AROMA OR Eclipse.
Your feedback would be amazing.
Thank you
Thank God im not the only one. Look at my thread http://forum.xda-developers.com/showthread.php?t=2455955
maybe we can find a solution together. Im using CM 10.2 but i live in Mexico son i had to flash my carrier's modem and it seems its coming back to normal but im not totally shure... still testing this modem (all info is on my thread)
Let me know if you find a fix... thanks

Wifi broken after modem update

I know this question is floating around the threads in developement and Q & A but i couldn't find a solid answer, I apologize in advance for creating a new thread.
So earlier today i followed these instructions ( http://forum.xda-developers.com/showthread.php?t=2338919 ) to update my modem to MK2 , Before that i was on the build that was right before MF9, I was, and currently am, running stock rooted touchwiz that came with the phone when I got it. Since i got it until today the only thing i've done to my SGS4 is root it.
and now after trying to update my modem my WiFi is broken. I try to turn it on but it never turns on, my data works fine, and other than a slow boot process everything else works fine. Can anybody please tell me how to fix my WiFi????
Thanks in advance.
Did you happen to update to a 4.3 rom when you did the modem upgrade?

HELP NEEDED. Lost GPS after 2 months of no issues

$20 via paypal to the person who can get me up and running again.
GPS is very important for my line of work, and I'm trying not to panic.
I'm on MK2. I've been using stock and SHOstock ROM flawlessly since getting the phone just before Christmas. I've NEVER had any GPS issues. Ever.
I decided to flash the Safestrap version of Hyperdrive on ROM Slot 1, along with MK2 kernel module. Installed fine. I flipped back to STOCK rom(SHOstock), until I had time to mess with the new ROM. On the way home from work, I realized I had no GPS.
Using GPS Tools and GPS Fix apps, no satellites showing at all.
I've done everything I can think of, including using ODIN to flash back to stock MK2. Still no dice.
Can anyone give a guy a hand? I'm currently running stock and have re-rooted using saferoot(the same way I rooted previously).
Thanks in advance!

Yes, I've had that message forum(2nd link) saved for some time now. I've done everything in that thread and used the GPS app tools, and nothing has helped. Can't locate ANY satellites.

Nothing has happened to the phone(no drops/spills/etc). It started right after flashing the new ROM, so I'm fairly certain it has to be related.
Did u try flashing older modem / baseband. .... I read that couples people confirmed by using MDL modem. .... check your PM....

Ted, per our extended private message convo on Friday, thanks for giving me a good shove in the right direction!
Dlp22, I have the same problem, did you solve it?
any suggestion!
I had the same problem after upgrading to MK2, almost on the verge of getting rid of GS4 and switching to another device. But for now, I have fixed it by installing Hyperdrive RS13 using Safestrap on Stock slot (did take a backup of the stock slot before wiping it out)...

[Q] WiFi unstable stock rom; CM11 possible cure?

My AT&T S4's wifi connection has become basically useless. Both at home and at work it frequently drops out and says the connection is unstable. At home, this happens when I'm in the same room as the router. These symptoms started happening after the OTA updates, but seem to have gotten continually worse. I've tried the usual settings changes to no avail.
Is there any reason to believe that putting a custom rom on my S4 will solve the wifi stability issue? If so, I'd happily give it a shot before I completely give up and get a new phone. And, I've had the hardest time trying to figure which guide to use to install a custom rom. I have a US AT&T SGH i337 that is running 4.4.2, and the Baseband version is I337UCUFNC1, Kernal version 3.4.0-1125940. I rooted my s4 using towelroot.
Thanks for the help, hoping I can fix my S4 and keep it...
If it were me I'd flash the nb1 tar file and see if I had the same Wi-Fi issue. You might have a hardware issue. If everything worked then I'd take the ota to nc1. If you have a problem now it's probably the modem image.
Use the rootable nb1 tar file, it's rootable with towelroot.
Flashing the tar in Odin will wipe your device so make sure you backup first.

Wi-Fi Stopped Working

I noticed last night at some point that I lost Wi-Fi functionality on my S4. All other devices on my home network are working without incidence. Any ideas?

I'm having the same problem. My wifi is now working whenever it wants. I didn't have any issues either until yesterday. I was running the GPE 4.4.4 rom by joe-tech and was getting annoyed by the 5.0 update notification. So I got autostarts and disabled the 3 services that check that. After a while, I noticed my wifi stopped working. After countless reboots and hot reboots, the wifi just works sporadically even after re-enabling the 3 services I turned off for the 5.0 update. I wiped cache/dalvik thinking that might fix it too and nope. I wiped the phone completely and installed the latest GoldenEye rom (v48) hoping that would fix it. Nope.
I can be on wireless and it'll just shut off by itself. I'll turn it back on and it turns temperamental.
Please help us
I had this issue too.

I had rooted my fiance's Galaxy S4 and when she wanted it back to unrooted and stock, I put it back. However, it appears that the common recovery that is available online is available with a kernel that is either corrupt, or just plain wrong. Her WiFi would not turn on despite everything. After much searching and attempts at removing the battery, factory restore and whatnot, finally decided to research the flash file itself and sure enough, it would not update past 4.2.2.
The file you will need to reflash via ODIN v1.85 is available here: http://www.androidayos.com/samsung-galaxy-s4-odin-stock-firmware/
Found the proper file (Telus), flashed it and it is now at 4.4.2 and WiFi is working perfect again. Also fast as well. Hope this helps as I know I found it extremely difficult to find answers!
I should have posted by now. My Wi-Fi returned. Weird...
