HELP! WiFi Issues - Galaxy S 4 Q&A, Help & Troubleshooting

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.

Hi mate ,
Try flashing a new modem it never hurts but wifi is kernel control , see what kernel you had before when it was working good ,check if it was changed in the las upgrade... reflash old kernel again or try a different one

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.

I flashed a modem *read above* and nothing's happened... I even tried flashing WiFi fixes and it hasn't done anything
I didn't know kernels could fix a WiFi problem, I might try that.

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?

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?

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.

Did you flash an alternate kernel?
Wifi issues are often kernel related. Not always...but often.

Can someone please help a non techy flash to JPY ?

I am on the 3 Network(UK), my phone is branded, no lagfix, no root, im on froyo 2.2 oficial upgrade through kies.
Can someone please give me a simple step by step guide on how to upgrade to the JPY 2.2.1 firmware please, i have the 3 button recovery option btw.
Thank you in advance.
Simple: flash with odin (read the stickies...)

I'd go for a custom rom jpy based like docs or darkys and install through clockwork or you can go to samfirmware to download jpy and use odin to flash it up to you or just do as above and use patcher but jpy is definetly worth it.
The first time i tried the kies patch utility i got a messags saying there were more than 1 phone folders which threw me a bit, but managed to sort it in the end.
So now on ....
2.2.1

Hi Kayno
Set the "Enable Spoof" to True
Set "Spoof product code as" to XEU from the list
Then click on the Write Regstry button in the bottom right
Thats all you have to do, then voila when you start kies and connect your phone you should have a popup saying a firmware upgrade is available.
Good luck

Also did you save the Rom through Kies. Was a bit confused when i read this part on the Kies Registry patcher thread.
By the way hows your experience with the new firmware been so far. Is 3G and WIFI working correctly. Have you tried the app market. Hows the overall speed of the phone and is gps working better now.
Sorry for all these questions but i just wanted to determine whether the risk of updating is worth it.
cheers

No, i didnt save the Rom, 3g and Wifi are working fine but you will lose the My3 app because you will be basicly debranding your fone(if you are on contract), but if you start the default browser it takes you direct to My3 .
Havnt tried GPS , dont use it tbh.
The speed of the phone is so much smoother imo, im so glad i upgraded.
Hope that helps

Jaytwo,
My installation failed. Did you manage to flash it on the first go. I did exactly as you said. The thing is it finishes downloading in about 15 mins then fails installation. I also had the multiple folder detected problem. I clicked on ok on the registry patcher to delete the folder and re-started keys with the sgs connected.
The phone disconnects and after about couple of minutes is says Failed to convert to upgrade mode. Please try later.
Does anyone else know how to fix this? Am i doing anything wrong
thanking you in advance
Yes it flashed first time for me.
When the phone disconnected did you do anything?
I noticed when i flashed that the phone disconnected but i didnt touch anything and left it to carry on, it took a while but all went well in the end.
Try flashing again, just to check do you have the 3 button recovery option on your phone?

Hi Jaytwo,
I have not touched the phone when it disconnected as i remember from a previous upgrade to Froyo from Eclaire when it disconnected and then reconnected before completing the upgrade.
I have the 3 button recovery i checked it. The wierd thing is the phone did not reboot to downloading mode where the yellow android digging man picture appears. The phone stays as it is. I wonder whether samsung changed anything recently.
kingconnought, on the main registry patcher thread also mentioned he is experiencing the same problem.
Can anyone else help.
Thanks again
I dont understand why your phone will not go into download mode as that is part of the flashing process.
Try doing a factory reset through settings on your phone, then try flashing again, apart from that im not sure what else you can do apart from flashing thru odin?

LOL... This will be my 5th time.
By the way i thought il tell you this. If you ever want to for God knows whatever reason re-brand your phone to 3 then select the H3G product code and it should Flash your phone to the latest 3 branded Froyo which is JP5.
If i have to resort to Odin then i might as well wait for 3 to update their version to 2.2.1 as im too scared to Flash via Odin as there is too many risks associated with it. Or who knows Samsung may decide to release another version which might work.
Thanks
I got a quick question about this subject. Ik have no experience without android firmware flashing. Do ik need to backup stuff like imei number? For when the **** hits the fan. And if so how do ik do that?

It was 5th time lucky thanks to your recommendation to factory reset the phone. i factory set the phone again after upgrade and it is taking off like a rocket. Still yet to check everything but i have lost access to My3 as you said. I will let you know if i can manage to get access again.
Thanks for all your help mate. I apreciate it

[Q] i9505 - No reception, black screenfreeze, no sound

Hey all, i got this serious problem.
I've flashed most of the cutom roms right after buying the phone but at some moment i decided i wanted to return to stock again as the phone was behaving weird. I did, was a TNL 4.3 dutch stock rom. After some months i began to encounter no reception problems, it first started once a week for a whole day then it was 3 days problems 1 day reception. I then decided to flash a new 4.4 custom rom to see if it solves the issue but it didnt, i tried to flash a 4.3 rom and then the no sound/black screen/ phone dialer freezes started to occur. I flashed the 4.4 UFNA1 modem, it still persists, i flashed the nightly 4.4 rom and reflashed the UFNA1 modem twice (which was done correctly) and i still have no sound etc... What am i doing wrong here? I feel terrible as i also have no warranty left ofcourse.. Btw. I tried flashing to several stock roms by ODIN which coused the program to freeze and the phone went into a bootloop, which could be fixed by just flashing a custom recovery, and after that ofcourse a custom rom.. Very strange! Someone has an idea??
thanks

That's the biggest issue and iv've read a lot about it on the net, nobody could seem to fix it. Lots of em said it was an internal error which got fixed by their warranty (they say they got new phones, up till 3 times..) They tried replacing sim/sd bay which didn't solve a thing. Anyone else experiencing this problem and got it fixed??

Hey, didn't i just flash a modem? Which fixed the sound/freeze bug etc? What if i reflash another (4.3) one and get that old problem again? (im on 4.4.2) I tried selected gsm/lte/wcdma settings manually, the phone was totally dead. My little brother who owns exactly the same phone and carrier (tmobile) have had 0 problems with his phone, he never touched it though and only recently upgraded to 4.3 by KIES. I tried switching out sim cards and my card worked on his phone, but his card didn't work on mine.

We already fixed the Sound problem and Im sure that signal Dropping issue can fix it easy just flashing a different modem/ or setup the right APN.
Hey all, the XXUFNA5 modem helped out great, untill today where i'm getting no reception at all again.. i'm on the Google Edition 4.4.2 rom prerooted for about 3 days.

Come on guys, not one reply? This is urgent, need some help!
I'm having this reception problem ever since I got this phone from my friend overseas I tried everything flash stock ROM ,change modems, flash custom roms and still no signal I tried different Sim cards also, I'm guessing maybe something is wrong with the main board? So I just gave up and started using it as a media phone alone

[Q] No Audio

Hello, a few days ago, my brother rooted his galaxy S4 with Odin, then he decided to go back to the stock version without root permission. But during the installation of the firmware, the computer is turned off. So I decided to try again to install the firmware with Odin. The installation went fine, but the audio and the wi-fi didn't work. So I decided to install a recovery (jflte cwm 6.0.5.0) and install the latest nightly of CyanogenMod 11 Now the wi-fi works perfectly, but the audio doesn't work. I have done many tests reading on the forum, I also changed kernel but nothing.
Can anyone help me? Thanks in advance!

I am facing the same problem, I've been running CM 11 nightlies for a looong time though.
I hope that we somehow can get an easy fix for this.
All audio
For you guys, does all of your audio don't work, like you can't call, play YouTube or music?

Yes, the dialer doesn't work, in the audio settings I can't hear the different ring tones. If I raise the volume up you I can't hear the classic " beep " .
So completely without audio.
Thank god, I thought I was the only one, no fix either as far as i know. Looked on the internet for one for an hour yesterday too

If you cannot find your modem file just type in your model name with modem to goodle, install with ODIN good luck!

As I have the international model, I am quite sure that it is the right one, and sammobile.com agrees with me.
PDA: I9505XXUFNB9
CSC: I9505NEEFNB2

damn, maybe try different modems idk..... Cause I think that the modem is the problem, we'll at least for me it was.
I tried to flash different modem with Odin, but nothing.
I tried:
XXUGNG2
XXUGNE5
XXUBMF8
But no, the audio doesn't work!
Hi,
Yes the problem is related to modem! But to get it working again it's not necessary to go to the latest modem, actually it may not be the solution! Try installing the Galaxy Info app from Play Store ( https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo) and check your bootloader version, with it you'll have to flash the same version of modem as the bootloader you have.
If that doesn't solve the problem, you'll have to upgrade your modem, just change one version above and keep trying until it works. I know it's tedious, but that's the method I use and always worked .

I've installed the Galaxy info app, and my bootloader was equal to XXUGNG2.
So, I've flashed with Odin the GNG2 modem first, then the 4 and the 8. But the audio still doesn't work.
So, I've flashed with the GNG8 modem his correlated bootloader, but the problem still persists. Any ideas?

Hi,
Not many ideas here. But anyway, just in case you want to try I'm using XXUFNB8 bootloader with the XXUFNB8 modem. If you are running a bootloader newer than mine don't even consider changing your bootloader, but maybe the modem may help.
If you are sure you tried as many possible combinations of BL and MDM, then try flashing another zip, as this one may be corrupted...

Sent from my GT-I9505
My sound still comes and goes as it pleases.. It seems like it is having its own life - Sometimes it stays for hours, then goes away for 10 minutes and sometimes it's the other way around.
Anyway, I've tried the phone-info app, and my bootloader (as expected) is: I9505XXUFNB9.
My Baseband version is also I9505XXUFNB9. PDA and CSC are both blank.
It still bugs me a lot I must say...
up, same problem here.
I've tried everything.. Any news?
So.. Just wanted to update you guys..
I've now been "with sound" for about 20 hours, which is a new record, and I think that it will stay.

Wiped EVERYTHING - Internal SD, External SD, Data, etc.
Flashed EuroSkank 22-10-2014

I can't send or receive MMS unless I unroot :(

So I know this is a weird issue. I've done my research and tested way too many times before posting this up
OK, so the problem is that I can't send or receive MMS on my LTE network. Also, I believe this causes me to have problems with my GPS as it sometimes it can be detected and sometimes it won't.
The steps I've taken to rectify the problem:
1. Completely unrooted phone and flashed stock firmware from sammobile.com.
2. Checked if MMS and maps were working on the stock firmware and they were. I checked the USSD code using *#1234# in the dialer and it was working.
3. Done the rooting process and flashed new recovery and new ROM.
4. Tried to send MMS and issue persisted again. Also, when I send the MMS it disconnects my LTE and stays disconnected till I reconnect again.
5. I checked the USSD again and it says "Connection problem or invalid MMI code"
6. I have flashed so many different modems and bootloaders and the problem is still there. Unless I unroot and stick to my network provided ROM.
7. I checked APN settings, manually set new ones up using the network APN settings and still nothing.
What is the problem here? Is it my phone? A hardware issue? WHAT THE..
Any help is appreciated :fingers-crossed::fingers-crossed::fingers-crossed:

I have no answer to this, but you're not alone.
See : http://forum.xda-developers.com/galaxy-s4/help/i9506-temaseks-unofficial-cyanogenmod-t3204676
As far as I can tell, we're both having the same issue with MMS.
I recently tried various things, including a fresh ROM re-install (with everything wiped) : with the stock ROM, MMS are working fine but with anything CM 12.1 based, they aren't (unless I'm connected to WiFi, as I explained in my post, which points to a data connection management issue).
I also tried the latest modem available (CM 12.1 based roms were using XXUDOC5, I'm now on XXUDOF2), to no avail.
Have a nice day all

As that rom is based on this rom, search this thread for anything related to mms. If it works on wifi then it's 100% a wrong apn setting or maybe a bug.

It's definitely a bug. I've already tried everything to do with my providers APN. I installed so many modems as well no luck whatever. I'm pretty sure is an easy, small script that is an easy fix for a developer =/

I don't think the fix is that easy for them because there are already a few patches applied in the past for MMS. Your best bet would still be to search that thread I gave you and see if someone came up with a fix.

i9505 loses wifi connection again and again

Hey guys,
I'm using a i9505 as a media device at home. As opposed to all my other devices this phone loses its connection often every few minutes and also often doenst reconnect itsself. Its super annoying. I cant stream nothing or make a internet call.
Has anyone any idea? Flash a modem?
I'm on LOS 16.1

Flashing a modem won't hurt. You should be on the last one for your device anyway.

Does it really not matter whether I download the variant of my country (...HPK2) or the latest without my country code (... HQK1)?

Your carrier stopping at HPK2 simply means they didn't bother putting any work into what to them is a minor update. HQK1 will work on your device without a problem.
Hey again, I flashed the latest STOCK I could find on my i9505. But with STOCK i even cant enable wifi. I already did a factory resst but it doenst help.
Should I try flashing any modem? Or what option do I still have?

If you unpack the ROM package I believe you will find a .bin file for the wifi you can flash in Odin.
