[Q] No WiFi on any stock rom

I have tried flashing numerous times two different stock roms for my S4 and all the times, the WiFi doesn't work, I have tried flashing the WiFi fix heaps of times too but it doesn't seem to do anything.
And sound doesn't work either?! And it dies when I try and make a phone call, I think that's down to a dodgy Modem file
WiFi works on CM10.1 though but I don't like it and prefer the stock roms, any ideas?

WIF/Network/Modem problems

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] Why does my Wifi & Bluetooth not working even with stock rom?

Hey guys,
I have a Galaxy S4 (i9500). I installed Omega ROM v22 on it and everything went smoothly, Wifi & BT working perfectly.
After a few hours of using the device (nothing special at all, texts and stuff like that) - I noticed my wifi isn't working and by not working I mean that I click the wi-fi button and it changes from gray to the mid-state between gray to green for around 20 seconds before it goes back to green ago.
If I open the menu to see my networks it just says "Enabling" without any networks there.
I had to drive somewhere so I went to my car and tried to enable Bluetooth, and same thing happens there - Bluetooth will not turn on and will stay stuck on mid-state between gray and green for a while and go back to green.
I flashed omega rom v22 again and the problem was gone, or so I thought. I went back to the car for another drive and realized the bluetooth issue is back - and when I got home I realized the wifi issue is back as well.
I figured I need to reset everything so I tried the following:
Full wipe (including dalvik and even including "internal SD card") and then flashing stock rom (from the official website, stock rom of my country).
The issue was back after a few hours. I do not have BT or Wifi access. Yesterday Wifi suddenly started working for a few hours but then it stopped working again.
I really need help! I have no idea what to do with this issue!

Well rule number one when you have problems after flashing without wipe.
1. perform a full wipe and see if the problem persists.

Tried that, no luck.
What else would you try?
In some places when people had problems with Wi-Fi they said to flash a different kernel but I don't see why I would have this specific issue with Omega Rom and why the default kernel with it wont work well?
Maybe this could be a root issue? My root works fine but I have this weird gut feeling like this is some permissions thing that's going on.
I'm trying to think why it would work right after the wipe but then stop working shortly after.
Another symptom: It randomly started working for a few minutes and then stopped again (around three hours ago).
Any idea what's going on?

Well, if you fully wiped and didn't restore any apps and settings then it can be two other things.
Or it's a bug in the rom or a hardware failure in your phone.
I would suggest trying a different rom first. Do not restore anything, not even your google account.

wi-fi fix?
Do you actually have an i9505? or is it a canadian or att version? if its the latter sometimes the devs offer some wifi-fixes, also try a different kernel. otherwise it could be that your radio/modem are not compatible with the version of the ROM you are flashing.

Tried arrow ROM and this issue doesn't seem to happen in this rom. Hope it stays like that...

Sadly, it did happen with this rom, after just a few hours.
I'm now using stock rom and still suffering from the issue.
Does anyone have ANY idea what I can do to fix this?
Thanks in advance!

Samsung S4 i9505 Wifi issues

Hi, i would like to find out when there is continuos problems with my wifi. At first the wifi would turn on completely after the icon was tapped. Then it stopped working all together. I fixed that by flashing Lollipop from SamMobile. Then about 2 weeks ago I tapped the wifi icon and it would stay dim green as if it was turning on and then it would turn off by itself in 10 seconds.

Ever tried flashing a rom or something?
AFAIK there is this bug in stock firmwares. Many have had this problem. Try cleaning the cache using recovery. Might help.
Or maybe try flashing a better modem.

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?
