Galaxy S4 doesn't work properly anymore.

To preface the current issue with my phone, I guess I should probably give some history of what I've done to it. I got my S4 around November last year, where I kept TouchWiz for about a good 3 months. At the end of those 3 months, I downloaded and installed CM KitKat using their easy installer and it worked! However, when Lollipop came around, I got a little impatient and decided to get CM12 using Antares version. Initially, I noticed there were a few bugs/glitches, but ignored them for the time being. As time went on, it became increasingly aggravating and so a few dayus ago I tried to switch back to stock TouchWiz. When I was setting up the phone, I noticed that the wi-fi would just not turn it. It would stay at "turning on" for a very long time with no sucess. Thus, I decided to switch back to Antares version of CM, but now there were a few issues: service was VERY spotty and the piece de resistance: no sound at ALL, and youtube would never play videos. I searched around and saw that using the Sound Recorder would give me an error: "Internal Application Error. Microphone may be in use." Now I'm not the most techy person around and probably should not have been messing around with my phone, but now all I want is a properly working phone, doesn't matter if its kitkat or lollipop. Your help is greatly appreciated. (If you need to know more info, go ahead and ask, because I'm very new to all this) Thanks!

If you want the stock ROM back, flash it twice using Odin. General consensus here is that you need to flash the modem twice in order for WiFi and cellular radios to work properly. Flashing the ROM twice will do that without having to track down just the modem file and trying to flash that.

Unfortunately, it doesn't seem to be working :/ When setting up my S4, it's still stuck at turning on the wifi

I switched back to Antares CM, and everything works fine except for sound/microphone (to my knowledge). Would there be any way to fix this?

SM-G901F WiFi Pemanently Switch Off

Hi All
I have an issue with my S5 Plus (G901F) a few days ago I rooted, TWRP and installed the stable MM ROM from Tkkg1994 and have been happily using my phone. This morning while I was opening the Gmail app the device rebooted and when it came back up I noticed WiFi was not on. Pressing the quick menu WiFi button turns it green for a second before going back to disabled. Likewise going to into settings - WFi and using the slider does not work either, it just goes back to off.
So far, I have wiped ART/Dalvik, reflashed BL and Modem, factory reset. Wiped the whole device and redid everything including diffrerent ROM's on the same BL/Modem (CPE1) and have the same result.
Everything else works, just not WiFi, I should also add I have tried with and without the SD card and disabling/enabling other radios (GPS/BT) in different combos has not worked either.
Has anyone come across this and can they suggest next steps?
I'm currently downloading the stock ROM that came with my phone to see if that helps.
Cheers

Stock ROM did not help.

Did you find solution? I have recently started to have same issue with same device.

Probably not. The S5 seems to suffer a lot by such issues. I bought mine 3 months ago in a shop. It worked for about 2 months very well. Then all of the sudden it became hot in my pocket so i had to quickly remove the battery. After this the device suffered by ocessional reboots. Nothing helped. Even trying to reflash the stock firmware by trying several Pit´s.
Finally got a replacement as obviously either the RAM or the CPU got defective. The other phone lasted for one week as the wifi module got defective there. Nothing helped either. Now it´s my 3th S5. This weekend my flashlight and camera stopped working. Fortunally got this fixed by reflashing the stock firmware.
Honestly I like the phone but it seems to be quite buggy. Never got such problems with my old S4 and am thinking about going back to the older device.

dude try flashing 4 files flash through odin

Samsung J5 2016 (J510FN) WiFi not turning on.

Hello.
I've recently flashed a ROM through TWRP on my smartphone. Since the ROM was buggy, I tried to flash the stock firmware, but I didn't know which firmware was my old firmware before I flashed the ROM. So I just installed AP_J510FXXU2AQA3_CL10498928_QB12376838_REV00_user_low_ship_MULTI_CERT.tar.md5, and it's working like a normal new phone before. But one problem, WiFi is not turning on. I've also encountered this problem when I was using a ROM. WiFi won't turn on. When I slide it on, it automatically slides off back. I already tried the WiFi fix trough TWRP but it also didn't work.
Please help me.

Flash custom kernel with wlan.ko

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?

Wifi stopped working after flashing back to stock ROM

I have what appears to be a demo device; this one will not do OTA.
So I installed the newer roms but then speech to text, the microphone would not work except only for calling. I downgraded to the stock rom and it was fine.
But I decided to keep trying I was hoping it might be something I did wrong and could upgrade. Still no microphone so I downgraded back to stock again. This time; Wifi completely stopped working. It will not detect any wifi networks. Some goggle searching said that it is possible the modem got messed up. Not sure what to do. I tried flashing again it didn't make any difference.
One thing I noticed though is the first time when downgrading I forgot to turn on USB debugging, but it still allowed me to do it and it went smoothly.
Having no wifi on a smartphone with no apps on it is a bad thing

Well some google search told me if this happens you can flash to the July Oreo update and your stuff will work. I did that and it worked. My ,ic still won't record sound so then I went back to the 7.1.1 and it works fine. Too bad I am stuck with nouget or my mic will not record stound and I cannot do OTA.
Here is the thread I found which was quite helpful.:

I just used the July Oreo update, the fastboot version.
