WIF/Network/Modem problems - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
Update: apparently its not broken because I did a full wipe and installed Echoe again, left MJ9 on it, and it seems to be working, for now anyway. -MJ5 was recommended by the developer
U2: Wifi stops working again.
I am worried that my s4 might be broken since any modem I try I don't get a stable wifi or the phone crashes when using GPS on a data connection (sometimes it works, sometimes the network drops and sometimes the phone crashes).
I was using Echoe ROM on baseband mj5 for a couple of months with no problems but lately the wifi problems started showing up and after reboots the phone would ALWAYS crash once at lockscreen (right after booting) and then it would work fine on second or third reboot. I upgraded to newer echoe but the same, so I decided to go to an AOSP rom and switched to Liquidsmooth (latest on 4.3). And I was having even bigger problems with network and slow wifi (on echoe the wifi problem was intermitent, on this it's always slow) and I didn't use to have GPS+Data network=phne crashes. So I went on the thread with all the modems and tried a few. the site http://www.sammobile.com/firmwares/2/ tells me that for my S4 i9505 on three UK the latest is I9505XXUEMK9.
All the following I tested on liquidsmooth rom and by reflashing this rom before and or after new modem flash
So I tried both XXUEMK9 and 8 but both are really bad, wifi drops and phone crashes (tried WIFI fix), then I tried I9505XXUEMJ9 without/with wifi fix and it seemed stable for about 5 minutes... then it crashed. This was on new rom flash after flashing moded, just to make sure... and it still crashed.
I used odin to flash all the modems
I use Philz Touch latest 6.something (I was on 5.something at first but changed it just to be sure)
should I try a modem that is not UK specific, is there an international one? <-- although, Im assuming XX means international so this would answer my own question.
Any help or advice is appreciated.
I would still like to know of a good modem for UK Three phone with AOSP rom
thankyou

[Q] S4 does not find my wlan when using aosp based roms

Hi guys,
I rooted my s4 (I9505), installed a custom recovery and went on flashing cyanogenmod (the official 10.1.3 RC). Everything seems to run just fine but CM does not find my Wlan network. It shows other networks though.
I thought maybe it is a CM bug so I tried the 4.3 google edition rom but I have the same problem there.
After reverting to a stock rom wlan works perfectly again
So I flashed CM again after a full wipe but the problem persists.
My SGS2 never had problems with my wlan at all (also running CM)
Does anyone have any idea what could be wrong?
Thank you in advance.
I do have the exact same problem
I own a Galaxy S4 Intl. i9505
i put CWM on it to install cyanogenmod 10.1.3 RC1
the device is able to scan the networks, but not even that reliable.
first i tried connecting to my wifi network using WPS. but that didn't work
then i manually put in my passphrase. it stored the network but didn't connect. neither automatically nor manually.
rebooting the device and/or turning off/on wlan doesn't work.
Is there a way to see some log files, or follow the system, what it tries to do and where it might get stuck?
baseband version: I9505XXUBMGA
question. is the solution maybe flashing another radio firmware?
cheers.

[Q] Problems with audio after flashing MGG

Hi!
I flashed a rom with MGG and got the same FC problems as everyone else. Flashed the stock MGG rom and cleared everything, factory reset etc. After that I didn't get any audio at all. Not ever during the samsung bootup animation.
I flashed another rom through cwm, same thing and no wifi. The wifi fix doesn't seems to work either.
Tried CM 10.2, there I'm getting wifi but instead no data trafic. Baseband says "unknown" even through I flash different modems. The wifi and data problems I can get around, its just that I can't flash older roms through odin until they unlock the new bootloader.
The audio problems in the other hand. Saw some guy having sound problems in the modem thread as well. Not to many have posted about this problem. Seems to be a pretty rare problem.
What could cause this, how to get around this?
Had to go to work with a non working phone so can't get any logs for you at the moment.
I'm concerned, please enlighten me!
Finally, flashed the latest CM 10.2. Got wifi and reception working!
Still no sound. What log would you like to see to find out what's wrong?

[Q] Unable to connect to mobile data

I finally got superuser working by flashing Echoe Illusion, the full touch-wiz version with Android 4.3. At first it seemed like I had everything working but the next day when I left the house (no longer connected to home wifi) I quickly realized it was refusing to connect to mobile data. I also cannot send text messages, and likewise I can assume I can't get them either. I have tried flashing the nightly CM11 build and 3G connected although LTE did not. I wasn't in an area where I expected reliable LTE anyway so that's not even an issue at this point because I'd very much like to use this Echoe Illusion rom, or another Touch-wiz based one. I just can't go downloading a bunch of them because I have a severe restriction on data usage and have already downloaded Echoe Illusion AND multiple other things. If it matters, my baseband ends in MJA.
I have also attempted to flash different modems with Odin, although all of them failed completely to flash at all and at this point I have to honestly admit I don't know what I'm doing. This is most definitely not my first time rooting...I'm just used to HTC phones, the Evos in particular. Thanks in advance if anyone can help or provide useful tips!
oh and P.S. I can't go back to the stock firmware because I must have flashed an incorrect kernel, and it borked the phone. I only got it working again by flashing a separate rom (Echoe Illusion) and have since flashed other kernels with no ill effect. I had a nandroid backup of the stock rom before I borked it, but every time I try restoring it, it stops at the yellow Sprint screen and won't boot.

[Q] Samsung Galaxy S5 SM-G900W8 Running Omega Rom V17 Reboots when WiFi Connects

Not sure if this is the place to post this question, but I've been searching everywhere and I haven't found anyone online who is having the same issues as me.
I installed Omega V17 (for G900F) on my Rogers G900W8 S5 a few weeks ago (didn't choose to use the Omega Kernel) and it seemed to work OK, but it seemed to reboot randomly (all of a sudden when I'm in the middle of doing something, the Omega loading animation would appear). I didn't update my modem, as my phone was reporting that I was already using version VLU1BOC1. I have been trying to find out what has been causing the issue. I reinstalled Omega, tried removing all apps, but it would still crash.
I finally started to notice a pattern while at work. When I would walk across to our other building, it would always reboot. The only thing my phone would be doing when walking across the parking lot would be disconnecting from the WiFi in the one building and connect to the other. I suppose the other times when it would reboot where when the phone would, for some reason, drop the WiFi connection and reconnect (or I'm assuming that's why it reboots when I'm stationary).
When I did the install, I wiped both caches and did a factory reset beforehand and it seemed to install fine, so I don't think it is an issue with the Omega install, but I did try installing Cyanogenmod and it has been fantastic (stable and fast). I would rather run Omega for Touchwiz, but it keeps rebooting and it's pretty much unusable in that state. I noticed that there was a new version of Omega (V18) for G900F so I was going to try that version to see if it might work, but I just can't at the moment (I should be able to in the next couple days and will report back with an update).
I was wondering if there is any way to confirm what is causing the Omega reboots, and if anyone else has seen this issue before?

Wifi not turning on (i9505 - Stock rom)

Hi. After trying a couple of custom roms, I wanted to go back to a stock rom via Odin. I actually succeeded. The phone boots, and android setup screen comes. But in the "wifi connection" screen, when I touch the button to turn the wifi on, it just refuses to turn on. It goes back to off position. I have tried several different country's stock roms (4.4.2 only, I haven't tried 5.0) and they all ended up the same. I just can not turn wifi on in stock rom. Wifi works in custom roms that I installed using TWRP.
Any idea why this happens?
By the way, I also tried flashing different modems, but the result is the same. I read that turning off the phone and removing the battery helps, however, in my case, it didn't.
Any help is greatly appreciated.
EDIT: As I have looked into the issue, some people claim that a custom kernel usually solves wifi problems. I haven't tried it yet but I will as soon as I can get my hands on the phone. Also in another post, I have seen a build.prop tweak "ro.securestorage.support=false" which is claimed to have solved the wifi issues. I am writing these to be of help to others that might encounter the same problem. I will update the post after trying these ideas.
EDIT 2: It turns out, when you flash a stock rom, Odin can't actually flash the modem partition. It seems like it does but it actually fails. You have to do it twice.
No Wifi
Hi,
have some trouble with my Galaxy S4 (GT-I9505). Since 2 weeks I'm trying to get wifi working. 2 weeks ago I decided to root the phone (everything complete stock Android 5.0.1). At this moment wifi was working well..
I did:
- Flash TWRP with Odin
- Flash magisk 18.1
--> booted phone..
Everything seemed to work well..expect wifi. It wouldn't turn on. When trying to activate the WiFi button by sliding to the right it stays grey and after 10 sec. the slider goes to the right side again.
What I've done:
Downloaded several stock firmwares from sammobile --> no wifi
Flashed serveral custome rom's (lineage 14.1, 15.1), android 5.0 and 4.4 based --> no wifi
Tried differnt kernels --> no wifi
Flashed different bootloaders and modems--> no wifi.
Tried to delete files in /wifi folder suggested here in forum --> no wifi
Tried to modify buil.prob set the security value to false suggested here in forum --> no wifi
I don't think thats a damage on the hardware. It must be a software issue?
Bluetooth and mobile data are working well. GPS and wifi seem to be broken.
After spedning weeks of flashinng, recovering etc.. I am frustrated and don't know what to do.
Any advices?
My wifi is not being enabled with this rom. Does anyone know how to solve?
