[Q] Wifi + LTE problems - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Alright. So mostly i don't post on forums because usually i can search around and find the answers elsewhere. But this time i couldnt seem to figure it out. So i have a GS4 i337m on stock with ktoonz kernel and the mg1 baseband. Ever since i flashed the ktoonz kernel i couldnt seem to connect to wifi anymore. tried installing multiple other kernels (even stock) with no luck. I eventually gave up and went to cyanogenmod 10.1 nightlys. This time, wifi worked but i couldnt get ANY sort of network access. I remember in my GS3 days i had to use a MMI code and change some things in there to get it to work, and im not sure how on this phone anymore. Now, i switched to the infamous rom with the same results as CM 10.1. I really preferably just want to get CM 10.1 working with DATA and not have to resort to factory reset. I know this forum is filled with geniuses lol, any suggestions???! Help would be greatly appreciated

Hi There,
Sorry i forgot which thread i got this from but each time i flash a new rom where i cannot turn on WIFI, i would flash this attached ZIP in recovery and it would resolve the problem. At least for my i337M

[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

[Q] Galaxy S4 i337m - NO AUDIO WHATSOEVER

Total Noob here. I have a GS4 (Canadian Rogers Model i337m). When flashing CM 10.2 I wiped dalvik cache, system, data, internal storage, and cache (to get all the samsung stuff off my device) and formatted data. After flashing, everything worked perfectly EXCEPT there is no audio from anywhere. No systems sounds, no notification sounds, no music (headphones don't even work), absolutely nothing. Does anyone have any suggestions? I've been racking my brain all day trying to figure something out. Thanks.
Stock firmware?
sent from my mobile device
Ive got the same issue, I was running OMNI rom until i got fed up of the phone powering off on its own. I decided to flash back to stock rom with odin then flash CM11 nightly. Thats about when I lost sound. Not only do I not have sound, the phone freezes up every time I use an app ( even dialer ) which requires sound. I've since tried flashing back to stock again in Odin, even trying different stock firmwares. I've still got the issue and the phone is basically useless as a phone without sound... Please help. Is this a modem issue? If so, how to I flash a new modem that will work, and doesn't flashing stock replace the modem anyway? Could this be a bootloader issue? I've been flashing roms and playing around with android for a while but I'd still consider myself a noob.
Same
I got the same thing here, No music plays at all, My phone completely froze when someone tried to call me. also complete noob at this stuff.
I did find a couple ROM's that were i337m 4.3. But none did anything, but did the same thing. All had no audio at all. I also get screen flashing a lot (That could just be my water damage)
Wouldn't mind finding an answer for this either!

I have yet to find a ROM that will let me Flash via Odin (Correction I did find one, but the same problems came up, no WIFI and no Audio), so the one I currently have is Goldeneye, which was flashed via CWM
Flash i337m 4.3 official firmware
You might wanna try flashing a new kernel. That usually fixes Wifi issues at least.

I use KT kernel. It's in my sig. Might be able to fix any other issues you're having too.
Hey MrKhozam thanks a bunch!
Sidenote, anyone know any Stock kernels of i337m? Or if they are even available for download. Or a way to get 'em?

[Q] Wi-Fi refusing to turn on... Help!

I currrently have a Galaxy s5 sm-g900v. Two days ago, I flashed Alliance rom via Safestrap and everything was great until my wifi starting acting dumb. It refuses to turn on, just hangs. I have tried flashing the modem, and Blaze kernel, hoping it would fix it, but no luck. I unrooted and Odin'd back to complete stock, and it STILL won't work. Somebody please give me some pointers on how I can fix it Help would be GREATLY appreciated.

i would do a clean wipe and flash stock rooted rom.
i had something similar but not as extreme as yours.
i was on ricks rom and it didnt autoconnect and id have to put in the password everytime i connected.
i clean wiped and installed stock rooted 4.4.4 and all is fine.
keep trying different roms if until you find one that works.

Youve posted this in two threads and althought it might work it has nothing to do with ricks rom as many others including myself have been using ricks rom flawlessly.. Id say wipe and flash the rom over again fresh and see if that works.. But saying try another rom isnt a good solution when ricks rom works just fine 99% of the time

Just giving help to those that need it based on my experiences. It just so happens that ive been on ricks rom and i had that issue. Nothing against rick and his rom but thats the situation and thats how i fixed my issues.
I believe when you are using safestrap you are supposed to flash the kernel modules to get Wi-Fi to work. Or am I mistaken about that?
Thanks guys, but I got it working by factory resetting from stock recovery.

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
