Hello everybody,
First of all, on 4.3 I couldn't get wifi to turn on. Here is a list of what I tried when I was on 4.3:
- I've already flashed many different stock and custom roms
- I've tried the wifi fixes, the non-hlos.bin fixes with every rom
- Friedrich420's build.prop tweaks and wifi files.
- Custom kernels
- Different modems
- Dial *#0011# and disable wifi power saving mode.
Now I've updated to 4.4.2 XXUFNA5 to see if that fixes the issue, but still no luck. Now it's even worse. No wifi and I can't even root the phone anymore (using cf auto root, haven't found another way yet but SuperSU sais 'no su binary installed' and closes...). However I can still install a custom recovery, but after installing any rom (4.4.2 ofcourse) the boot animation doesn't change, still says samsung, and I'm in a bootloop . Can't even install a pre-rooted stock rom. Tried both cwm and twrp several times.
I purchased the phone with the wifi problem, in the hope i could fix it and have a cheap galaxy s4. The previous owner said he hadn't done anything to the phone (no software of hardware changes). However konx was already 0x1.
Does anyone know what the problem can be?
Really no one with a possible solution?
why don't you try to clean flash with odin a stable rom?
I suggest 4.3 (you will have the knox issue, I don't mind)

The same happened with me.
I flashed the stock rom and the problem got solved.
I guess problem was with the kernels

have you tried a custom ROM like Cyanogen Mod?

Yes I've also tried a few custom roms on 4.3, but on 4.4 I ways get in a bootloop when trying to install a custom rom (4.4 ofcourse). Bootanimations doesn't even change. I don't think the error is in the system or the data folder, I've tried really everything within these folders. Can the problem be somewhere else? There's also a wpa_supplicant in etc/wifi, but that gets updated bij the wpa_supplicant.conf in data/misc/wifi right? So I don't think that can be the problem?

I am in the exact same boat as you except I didn't upgraded my bootloader to 4.4.2, was about to these days. I flashed about 7-8 different stock firmwares with the wifi fix for each. I, same as you bought the phone cheaper with this problem and thought I could fix it. I read somewhere that downgrading to 4.2.2 will help somehow but downgrading for me is impossible. I am getting desperate, please if you ever find a fix post it here or private message me. I know that is software and not hardware because in the first day I bought it I managed to fix it on the firmware it came with MK8 by flashing a lot of stuff in random order : CF auto root, wifi fix MK8, MK8 modem, philz_touch_6.07.9-jfltexx, don't remember what I did exactly, but made it work and then installed another stock firmware XXUENA4 , and it kept working on this firmware also all day long, and then next day after I started the phone it worked for about 5 min then it turned off and stayed off till now no matter what. I tend to be a rational person and try to find reasons for everything but for the life of me I can't figure out this one so really please help me, any one with any possible explanation. Can it be hardware after all? But how did I fix it once, and why can't I fix it again by doing the same same steps? My new plan is to try flashing bootloaders only as if this might work somehow. At this point for me is all about trying all sorts of mojo like flashing exactly 3 times modem then 3 times wifi fix, wipe data and factory reset from stock recovery before rom boots first time, and all sorts of wackadoo stuff.
Please really help me because my only other solution is to change the motherboard for 200 . Btw mine is i9505, u didn't mention yours.

Finally someone with the exactly the same problem! Yea mine is a i9505 too. I've also tried al those things like flashing 3 times without auto reboot etc, but nothing worked for me.
http://forum.xda-developers.com/showthread.php?t=2539904 some people say it is possible to downgrade the bootloader, but I haven't tried it yet because I'm afraid I will brick the bootloader and I don't have a jtag. What I'm now thinking about is to buy another cheap s4 with broken screen, replace the motherboard and sell the rest. I've tried everything with the software and put so much time in it, I think just replacing the motherboard is one of the only solutions left. But till the time I found one, I'll just keep trying. If you ever find a way to fix, I'd still love to hear it

Regarding your rooting problem have you read this ? Some one who helped a lot of people with wifi fixes advised me to try and downgrade with mobile odin, but still want to try a couple of 4.3 modems before downgrading. It s software but can't be fixed so frustrating!

Yea I used an outdated cf autoroot... But you can't downgrade to 4.3 once you've installed a newer bootloader, right? And I've tried about 20 different 4.3 modems, but no wifi with any modem

Well, my understanding is that if you downgrade with mobile odin, you only downgrade the firmware and not the bootloader and after you should make OTA update to the latest version and then it might work. Have you tried flashing CSC also and ticking re-partition, or maybe even fill out all fields in Odin instead of flashing just PDA(AP) ? I have never used Mobile Odin but will try soon and post results!

OTA isn't going to work since I have no wifi, but I guess kies will work too?
I've flashed csc also, haven't done re partition yet since it usually bricks the phone when I try it (or I'm always using the wrong pit files...). I've tried all the fields and just pda/ap.

There must be someone in xda who has a greater understanding of how bootloaders work how wifi works, how is modem related bootloader and to wifi and why this happens only to knox 0x1 and what to try, surely it cand be done. I will keep trying anything and everything and post here if relevant. I am gonna mention that at some point in time I succeded in making it work propely, so there is still hope. Hang in there!

Could be possible EFS corruption??
Do you have your MAC address still? Open EFS/wifi and check your .mac.info file.

Hello,
I answer here to help also someone else in case has the same problem.
Fiest thing: you wrote CDMA module, what variant is?
The GT-I9505 has a LTE/WCDMA module, not CDMA.
Have you touched something with secret menu codes? If you don't know what they are, the answer is no
What carrier do you have?
Have you roaming enabled?
You data plan reduces connection after a total GBs used at maximum speed?
Try to flash latest available modem fw along with latest bootloader, you can find them here

Thank u for ur reply,
First you are right I'm talking about the LTE/WCDMA module, and yes i messed up a little bit the with the secret menu codes but only after i got the issue, not before that.
I'm from morocco so the carrier is a moroccan one called inwi, the carrier does not reduce the speed, when u consume the GBs given the service is suspended.
the issue appeared when i was using wanam lite 3.1 i'm using wifi at home all the time so i couldnt notice until i went out and used data, i noticed that i only have edge in locations that used to give me H+, so when i tried to force wcdma by choosing wcdma only i got emergency calls only.
i messed around before with a couple of bootloaders and modems, I still cannot figure it out
your help is appreciated, thanks in advance
I had the same problem on Wanam. What solved it for me:
Use Shortcut Master (lite) to go to this menu: 4636
Then go to phone information and change the bandwith to something else. Then set it back to LTE/WCDMA or whatever works for you. Strange but it worked for me.

Get the network cable changed or change it yourself.
The only easy "non software" related solution.
Or maybe if it is in the software, tried flashing the stock rom or any ither custom rom after a full wipe.
Mine was with the stock rom but ozcan rom + data wipe has solved it..
Not i get H+ in only wcdma amd E/H+ in auto mode. (depending on the network area)

Sorry I'm a noon, don't do all those font sizes and colours and pictures aha but basically... I've been on CyanogenMod for about a year now and have never had WiFi issues. Been using cm12 nightlies for most of this year with no problem however, after updating my nightly the past two days I've been experiencing WiFi Drops happening every min and a half or so. So annoying. I've used Wifix apps etc, no luck. I've reverted to old night lies I used to run without any problems however the problem stays. I've consider flashing back to TouchWiz to see if that helps it but I really don't want to
Can someone please help me. My phone is on contract and my bill is overdue so I won't have mobile data until it's cleared (around June) so if I don't have WiFi, I'm screwed.

Have you tried flashing a new modem? This generally fixes wifi (and sound issues if there are any)
I barely know what a modem is haha but if that's the case, I'll try today.
Here you have a list of modems. Read the topic as it also has some info and the flashing guide.
You need to go to sammobile firmware checker and input your phone model, country and carrier. Then it will show you the correct firmware for your country and carrier. Based on that, download the modem. Make sure you get the latest modem. If you can't find the latest modem on the linked thread, there was another thread with all the latest modems, but I can't seem to find it anymore.

I'm on 5.02 CM12, I downloaded the latest modem for my GT-I9505 which matched the firmware code for a 4.4.2 S4 however still no luck ffs. This is really annoying, i don't know how my WiFi could jist shut off on me like that :/. Looks like I'm going to have to buy myself a new phone then. Can't use my mobile data for a couple months as my carrier has blocked me until I pay off my bill and now with my wifi disconnecting every 2 mins, I basically cannot use the internet. So frustrated.
I've flashed new nightlies, changed baseband versions, factory reset my phone and still no luck. What makes things worse is i cannot see any other threads with people in my postition so help is so minimal :/. Annoyed is an understatement.

Go back to stock firmware if you haven't updated the bootloader.
If it works fine on stock, then re-root your phone and try again with CM12.

Check and see i if power save is on , if so switch it off
Dial *#0011#
This will take you into the Service Mode
Press the left bottom key new menu will show
Select Wifi... Once in the Wifi settings , turn it off...
Do you have to refresh the password? just in case check this
Go to /system
Open the built.prop
search for ro.securestorage.support
If it says true , change to false
Save and reboot
Also if you are skill check the antenna cable inside the phone..maybe is just loose

Grrr... Power save is off
When I dial that code, the phone does nothing...does the fact that I cannot turn on my mobile data stop me from dialing this code? Also, does the fact that I'm on cm12 and not on touchwiz stop me from using this?
& I have no password on my phone and there was no ro.securestorage.support ... I found this "ro.wifi.channels=" if that helps?

& I have no password on my phone and there was no ro.securestorage.support ... I found this "ro.wifi.channels=" if that helps?

The code should work maybe is because CM , well last option would be to flash a stock rom and see how it goes........how you know power save is off?
BTW in your wifi setting there is no proxy ? did you try to delete settings and do a new one?

Damn really didn't want it to get to this, will I lose root access too?
Isn't power save automatically off in the settings? It gives you the option to use it in low battery
& I don't know how to check if there is or isn't proxy. What do you mean by deleting settings?

Updated by bootloader earlier today :s was told I had to do that to flash a new modem... Can/should I still flash back to touchwiz and if so, how do I? And say I go back to touchwiz and it Stoll doesn't work, my phone is basically unusable isn't it?

If you updated bootloader then you can't go back to kitkat roms. Only the 5.0 lollipop roms. But Samsung hasn't released the official update in all countries.
If it still doesn't work, even with official firmware, then it might be hardware related. Maybe even your wifi router.

Hi ,
yes can still flash an stock rom....but why you do not try first
flash a different modem
flash a different kernel
If every thing else fails flash a stock rom, what model S4 do you have I9505?

Hi, i'm going to flash lollipop touchwiz onto my phone using this http://www.ibtimes.co.uk/android-5-...-s4-lte-how-manually-install-via-odin-1492230.
Anything i should know/do before doing this?
Did you flash an alternate kernel?
Wifi issues are often kernel related. Not always...but often.
Hi guys,if anybody can be so kind as to shed some light on this question ,I would really appreciate it [emoji4]
My wife has an i9505 and me a 9500.
I flashed kushan rom5.0.1 for her ,and it works perfect (no problems)
Then I saw on her phone,if I play Clash of clans and the WiFi signal drops ,the phone seamlessly moves to 3g, which is awesome.
Now the problem is ,After seeing that I decided I must also upgrade to lollipop.
I tried two roms so far,namely Prism barebone and Vovad S6 lite.
And it disconnect each time I lose WiFi signal[emoji33]
Is there any fix or reason why it is happening like this,I thought it is the lollipop update that fixed this issue.
Cheers

Could this be due to the kernel.
I don't understand you ; you will have even more problems with android lollipop and secure download enabled + rollback protection !
Just reflash stock kitkat.

The problem is also in Kit Kat .The reason I upgraded was ,after clashing on my wife's phone ,I saw I could switch between WiFi and mobile data without losing connection in clash of clans.
I just don't experience the same after I upgraded my i9500 to lollipop.

Maybe the problem could be on the kernel (flash another one or flash stock frimware)

Hello guys.
I have an issue since I decided to flash a pie rom, specifically simplix blue, have no idea if has something to do with that rom.
I used to have LTE as normal and everything was good. Since I flashed a PIE rom I lost LTE. I tried going back to stock and LTE is still gone. Had tried flashing some modems, did not work either. Tried several radio combinations on *#*#4636#*#* did not work.
Any suggestions? I am on Tigo Colombia as carrier and never had this issue before across several xiaomi devices that I have had

Nope.
I had found a solution already. It is kinda long so tomorrow I Will post a guide. For some reason the band 4 that was the one that my carrier uses was blocked. So I had to unblock it
I have seen several people here with similar issues and not being able yo Solve it. Hopefully the tutorial that I Will make, help them as well.
I have the same problem, any way to fix it?

Yep, I have been quite busy, as soon as I have time, I will post a tutorial. Meanwhile, take a look at this post, read first part of post 3 and then post 7.
https://forum.xda-developers.com/lenovo-p2/how-to/enabled-4g-ca-p2-t3707584
As soon as you finish adding the band, install network signal guru, provide root admin rights and then select on the 3 dots at the top right corner lock bands, select lte and pick up the band missing and reboot.
Also facing this, I'm waiting for tutorial.
