[Q] Wi-Fi won't turn on? - Galaxy S 4 Q&A, Help & Troubleshooting

Hi guys, I'm on an i9505 with stock ROM and everything. I had it rooted before and everything was perfect, but then I updated to 4.3, so I had to re-root. When I re-rooted, everything was still there - I just had to re-install Xposed. However, my Wi-Fi is not working anymore. Every time I click on the Wi-Fi to toggle it on, it flashes green, then turns itself off again.
What is the problem here? My build number is JSS15J.I9505XXUEMKF and my baseband versionis I9505XXUEMJ7. I rooted using CF Auto-root for I9505.

Thanks, I just tried it, but it didn't seem to do anything. Still turning itself off the second I turn it on.
Is it perhaps because my baseband version is not the same as my build number? I don't know much about the details and intricacies of how this stuff works, I only know the basics, but that's an idea that came up.
Or maybe I need the Wifi fix for UEMKF (my build number) rather than UEMJ7 (My baseband version)?
I'm not sure. But just some ideas.

Download and Extract ,then Power Off your device completely and wait a few sec and Press and hold Power+Volume down in order to reach download mode and flash it via odin, and go to settings and check your baseband if the flash are okey.
**If you are having the new bootloader XXUD flash http://www.mediafire.com/download/zriv6i5c01lqns6/GSM_Modem_XXUEMFK_and_LTE_Modem_XXUMFK.rar file with odin by selecting phone.

Glad that helps , Have a nice day sir.

the wifi problem doesn't accour cuz you root your phone it happened to my me and i was not rooted and nor flashed anything. you wake up and boom wifi won't turn on. and i use my mobile data cuz i can not turn on my wifi anymore. some say it's a hardware issue. some say it is a firmware issue. i don't know. i can't solve the problem. even i pay a technician to repair the phone buy they couldnt eighter. so i feel dumb when someone says this worked for me or that solved the issue. i did everything and i have not much money to buy a new one

No Sound, Tried Multiple Fixes i9505

I've got a Samsung Galaxy S4 i9505 Australian Model. The Snapdragon one.
I initially had Omega V10, I upgraded to V18 and the sound turned itself on and off, but then it started rebooting randomly and sound stopped all together. I upgraded to V19 with the same issue of no sound after the first call is made. I re-installed V19, V18 & 10 a few times. I flashed the appropriate modem for my old boot-loader several times on each rom and done clean installs as well.
I then moved to the Pheonix ROM, Installed exactly as the instructions stated. I then installed the modem as per instructions as I was having issues with the GSM/LTE then after the first call sound stopped working all together. I flashed ROM again and again, flashed the modem again, flashed a Wi-Fi Fix modem, flashed the kernel a couple of times and sound still doesn't work. It's every time after the first call is made, it just disappears.
I then decided to do a stock recovery in Odin. I installed official stock firmware XXUBMG4. Still no sound, I was getting the sound on boot but now it's gone all together.
What's my next step here? I'm almost certain I didn't flash an incorrect modem file but maybe I did........Should I try installing official 4.3? Is this something to do with installing a modem that's higher than what I should have installed and now I can't go back but only forward eg: 4.3?
I've lost root now as I flashed the official stock firmware via Odin, I'm happy to do whatever it takes to get the sound working. I'm not fussed at all about warranty.

Before you flash the file your downloading now would you mind Downloading and extract this file (You should see GSM_Modem_XXUEMFK_and_LTE_Modem_XXUBMH1.ta r)then flash the http://www.mediafire.com/download/48r0rgqv25s8968/GSM_Modem_XXUEMFK_and_LTE_Modem_XXUBMH1.rar file with odin by selecting phone. I want you to turn off your phone manually and wait a few sec and Press and hold Power+ Volume down Until you reach Download mode. Now open odin and select PHONE/CP and flash away. Have a nice day.

I just flashed this but it didn't fix the sound, as soon as it loaded I had an error coming up in the notification bar asking me to reboot as something was detected, something along those lines. It's the first time I've seen that error come up...is that something to do with Knox?
I'll flash the file the firmware I'm downloading now in 10 mins then see what happens. Or should I flash the firmware then flash this modem after?

Okey Im guessing you have the new bootloader since you said "knox" try to download and extract this and flash the http://www.mediafire.com/download/hdzf6fbobotxi61/GSM_Modem_XXUEML4_and_LTE_Modem_XXUML4.rar file with odin by selecting phone. This is a fix only but if the problem still persist feel free to flash the file that other guy gave you. im only giving you this fix just because alot of people had this problem that got fixed.Go to Settings and make sure that modems flashed ok

Ok no worries. I've already flashed the other firmware that the other person gave me. I'm now flashing this modem as the sound didn't work still. I didn't have Knox until I downloaded the firmware the other person suggested to download. I don't care about voiding Knox as I don't need it or use it.
I'll see what happens when I flash this modem. Thanks!
Ok, so far I've flashed the Official Stock Firmware XXUBMG4. I then flashed the GSM_Modem_XXUEMFK_and_LTE_Modem_XXUBMH1.tar. I then flashed the OPS 4.3 Firmware with Knox, I then flashed the XXUML4 Modem. None of this has fixed the sound, I'm not also getting random reboots every 30 secs or so.
So frustrating!! Why so complicated :S :S

If you just got a new bootloader aka Knox warranty Void that's okey , flashing any modem wont void your warranty . But if you flash a custom rom/Root then its over.If your knox got void means no more warranty for your device. Have a nice day.

Yeah still not working. I've tried different versions of Odin and run them as administrator in windows. I've tried 2 USB Cables also, Is it something to do with the PIT file? I was reading something about it from here:

Put off ur battery and put in again
Reboot into Download Mode (Vol Down + Home button combi)

[Q] after new baseband no calls

Hey friends,
I really looked everything up, but I could not find anything what helped me with my problem.
I have a Galaxy S4 (GT-i9505) and I wanted to update my modem from MKE to ML6. Because I had some issues with updating it (there still was the MKE at my "Status" after updating to ML6), I tried to double-overwrite it (someone wrote at a forum, that that will solbe the overwriting method). So, I started Odin 3.09 and deleted the "Auto Reboot" option. After the first flashing, I took out the battery and replaced it again. Then I did a secound modem flashing. The result was: There was still the MKE modem AND I cannot call anyone. Everytime I try to call someone and I click the call button, my Galaxy seems to crash. The screen is getting black and I have to shut it down by holding the power button for several secounds. Of course, I already tried out other modems (like to MKE modem again and MJ8), but the problem still exists.
Could anybody please help me!
Thanks,
Robert
Have you tried changing rom + modem? you cannot just randomly try modems with a certain rom as some will work others not.

Thanks, but that is what I have done at least ten times. I tried Odin3.04 and Odin3.09. I tried MKE, ML6, MJ8. I tried Google Roms 4.4 and 4.3, as well as other custom roms. That's weird!
I have never had any luck with 3.09 i always stick to 3.07, where are you getting your modems rom?

Which tutorial do you mean?
btw: sending a sms works, as well as receiving....but no incoming or outgoing calls
Had the same thing yesterday, tried all sorts of modems, with no avail.
Ended up flashing a stock rooted Rom (MGA), flashing a custom recovery and restored a Nandroid. Forgot that flashing a complete stock Rom usually also wipes the internal SD so that was a bit of a hassle.
Now, running a new Rom again, with Wifi, sound and being able to make/receive calls again. Easiest fix also: flash a (compatible) stock Rom :good:

Thank you mate. I also found (5 sec before I read your post) this post here: http://forum.xda-developers.com/showpost.php?p=46969768&postcount=2
So, everything works now. The short version for other guys with the problems is:
- flash stock rom via Odin (PDA)
- you can find the stock rom for your country at sammobile.com
- also use the "pit-file" of the linked post (but I don't know, what the pit-file is changing?!)
optional:
- re-root your device again, because now it is not rooted
- new custom rom
Thanks for every help!!!

Except flashing the Wifi Fix was the thing I did to ruin it all. Don't flash a "new" Wifi fix using an old bootloader. You will lose sound/being able to make calls. It's the thing that messed it all up over here.

I was already on the new bootloader.I've flashed Original FW, Modem + Wi-Fi fix and it fixed my phone. (Possibly also PIT but can't remember)
It can be that our problems were different but produced the same problem.. I'm not a dev nor do I understand everything about Android.
I can be wrong, but that's how I fixed my phone. Just trying to help

[Q] How to fix I9505; no sound, no mic, phone app not responding

Summary: my I9505 mic, earpiece and speaker don't seem to work and cause fc/not responding on functions that use them (phone), what should I do to resolve? (I have flashed a bunch of ROMs, and a couple modems...).
Detail:
Ok, so firstly I must apologise for not recalling the somewhat random sequence of events which has brought me to this juncture... I was fiddling around with a few different ROMs and when I noticed the problem I sort of frantically tried flashing things to fix it (yes, I'm aware this is a very sensible approach )
I've flashed a few different ROMs and at some point flashed a new modem.
I noticed yesterday that I was not getting any sounds out of my phone, noticed when using the volume buttons, no beep; further investigation revealed the speaker, earpiece and microphone seem to have decided to take an indefinite nap...
Any suggestions on how to proceed with waking them up?!
There is a message in the logcat:
getDeviceForStrategy() speaker device not found
Though not sure if this helps at all.
Making/receiving phonecalls the screen goes black and either rings out to voicemail before I can answer, then displays not responding wait/close error or the other person answers and neither side can hear then same not responding error.
I've not changed the bootloader (as far as I'm aware...).
Wifi/mobile internet work fine.
Tried flashing an old modem, factory resetting, reflashing a ROM (currently CM10.2) but no dice... since I'm a bit lost I figured stop fiddling and ask for help
Current baseband: I9505ZHUAME3
Current bootloader: I9505ZHUBMF4
Any suggestions on how to proceed to un-screw my phone would be greatly appreciated. :good:

Flashing a wrong LTE/Wifi fix will loose your sound . in Old bootloader you can't flash any newer LTE modem than UBMH1.and for the New bootloader you can flash all the new LTE modems, including MKF etc.. So boot your phone into download mode and check if you have an entry of knox warranty void then you have newbootloader. and make sure you manually turn off your phone and wait atleast 10 sec and boot your phone into download mode and flash . (Because sometimes flashing a modem/lte doesnt work and need to do it twice.
Use Odin
Untick Autoreboot
Flash modem
Reboot once again into Download Mode using (Power+Voldown)
Flash Modem once more
Once done,unplug then reboot device manually.
If this doesn't work, try repeating the flash process again while rebooting manually and with auto-reboot option turned off.

Im still in oldbootloader and i just download and flash a custom rom 4.4.2 via recovery .. and incase something wrong with my phone in a future . iE Hardware related.etc theni can just flash a 4.2.2 and send it for repair for free... and about newbootloader , flashing any custom rom/rooting will triggered your knox , so feel free to flash the latest stock 4.4.2 kitkat if you dont care about your Warranty. But like i said you can still flash a 4.4.2 custom rom without flashing a newbootloader (Never flash a newbootloader , Make sure to ask first before flashing anything) Have a nice day.
Edited: @mrlizard123 Never flash a latest Wifi fix so you wont get this problem again. only flash a GSM MODEM. if your flashing a custom 4.4.2 rom then you need to flash a latest GSM MODEM base from your country. in order to fix dropping signal issue when the phone went to sleep.

I337 AT&T S4 - Return to Stock (No WiFi)

I recently bit off more than I could chew with my S4 (I337). I had 4.4.2 KitKat on it and wanted to root it to add teathering. I decided thought there was no root for 4.4.2 so I thought I would try downgrading to 4.3 then root. This seemed best because I didn't like the way the SD card is handled in 4.4.2 and some of my apps (like ftp server) have stopped working.
When I got the phone back up from flashing with Odin it says it has version 4.3. My WiFi will not turn on. If I slide the switch to on it slides right back to off and the phone tells me that an operation was block (can't remember the full verbage. I have installed and attempted to install many things on my phone. I have used recovery mode / Odin3 and Kies (Kies doesn't allow much).
At this point I just would like to get my phone back to 4.4.2 with the WiFi working. Then I can restore my backup and be back to square one with a lesson learned.
I have an I337 that currently thinks it has version 4.3 on it. The baseband version is I337UCUFNC1 currently. The build number is JSS15J.I337UCUEMK2.
If anyone can help I would greatly appreciate it. I have read and tried many things over a two day period and finally decided to ask for help.
Had this issue before on my Bell Canada S4, but don't recall exact way to fix it.
Think the solution was to find an older (might be newer) stock. I think I used a different version like the Telus Canada version as well and it ended up working. Then you update through kies after.

Wifi does not work because of the modem/kernel mismatch, i.e. MDB modem and MK2 kernel. Not sure what your goal was when you began flashing your phone but since you fortunately did not flash teh MK2 bootloader you are still able to locate the MDB full odin tar and flash back to stock which will resolve your issue.

It depends on what you are trying to accomplish. Are you trying to upgrade to MK2 or higher while maintaining your unlocked MDB bootloader?

If you don't care about losing your MDB unlocked bootloader you can get to the latest kitkat firmware by flashing the NB1 full odin tar from here:
http://forum.xda-developers.com/showthread.php?t=2674223, then once flashing is complete go to settings/more/about phone/software update then take the ota update to NC1 which is the latest kitkat version for our phone.
But what I would do is keep your unlocked MDB bootloader and since you already flashed the MK2 AP file you can get your phone running well again by flashing the MK2 modem: https://mega.co.nz/#!pwESna5I!YK7EKG37xXIG1ReB-Z-mfSMoXNkXQ9t2EdMK9ofgJKg
From there, there are still a number of options available to get to kitkat which I won't get into.

excited to give this a try. rooted with the downgrade method a couple months ago but left with a non-wifi device. my only issue is that the thread says it's for I337UCUFNC1 and our devices are on jss15j.i337ucuemk2. will this fix still work? I've heard on other threads on the subject that the modem kernel doesn't match up with the flashed rom or build number or something.

Do you already fix it??? cause i have the same problem
Same question, different thread!
Not even an hour ago did I answer the same question in a different thread: How do I get WiFi working on my S4?
Well here you go.
My original answer: http://forum.xda-developers.com/gal...-4-4-2-nb1-t2850878/post54978150#post54978150
The problem is, in order to get WiFi working, you need to install the NB1 modules, but to do that, you need to install Safestrap. However, you can not install Safestrap because the app keeps closing on you. There is a simple fix to this, which I will explain later. For now, just read this WHOLE post BEFORE you do anything, and keep in mind that I am NOT held liable if you mess up your phone. Use this at your own risk.
1.) Root your phone
If you're already rooted with something like SuperSU or Superuser, skip this. If not, read ahead. Download and install the Towelroot APK file attached to this post, open it, and click 'make it ra1n'. If your phone didn't reboot, now you have root (they need to trademark that). Now, down below, I also included the APK for SuperSU. Download and install it. Now open it. When you open it, let it install the 'Normal' way, not via the 'TWRP/CWM' way. Also, when it asks you to disable KNOX, say yes, wait a couple of minutes (it will still be loading) and reboot your phone. Open up SuperSU again, click 'Yes' to disable KNOX again, and now you have a good base to start from.
2.) Install Safestrap AFTER fixing the error
The error your are getting is easily fixed. Go to the Play Store and install 'SELinux Mode Changer'. Open it, grant it root access, and change the mode to 'Permissive'. Now, open up Safestrap again (you mentioned you already installed it), and it shouldn't force close. Click 'Install', and if the 'Reboot to Recovery' option below is not grayed out after that then it worked.
3.) Download and install the NB1 modules
On your phone, download the included NB1 modules ZIP file I attached for you, and once that is done you need to reboot. After the Galaxy S4 logo, you'll see a screen that says 'SAFESTRAP: DISABLED' and there will be a little robot. TIP: To enter Safestrap, press the menu button (physical, hardware key) under 'Recovery' at that screen. To continue to Android, press the back key (again, physical) under the 'System' tab. For now, press the menu button under 'Recovery'. Now, click 'Install' which should be in red, click 'Add zips', and navigate to your Downloads folder. Now click on the NB1 modules ZIP you just downloaded. Swipe to install, and reboot. This time, hit the back key under 'System'.
All done!
Now, Android should (and will) boot up, and you'll have working WiFi! If, for some odd reason, you don't have WiFi- do NOT panic! Just search around for the MF3 modules and flash those! All is good, all is good. A lot of this guide was taken from my post about my personal method of SIM unlocking the AT&T Galaxy S4 without the dialer codes or an AT&T SIM. It was just modified a little to work for you.
Remember, hit thanks!

Those are my exact words. Also, the attached files (NB1 modules, SuperSU, Towelroot, etc.) can be found attached to my post in the link above. Have a good night, and best of luck! :good::good::good:

Would I be able to use this fix?

Flashed lollipop, now i cant make/answer calls or texts.

Hey
So i flashed lollipop on my galaxy note 3 SM-n9005. I was on custom kitkat rom before flashing.
I used this rom: http://forum.xda-developers.com/showthread.php?t=2495688
I dont know what went wrong but i cant make calls/recieve calls, same with text-messages.
I followed installation-guide and flashed:
modem.bin
NON-HLOS.bin
Quote:
1. IN ORDER TO AVOID ANY MINOR ISSUES, PLEASE FLASH THE OFFICIAL LOLLIPOP
MODEMS VIA ODIN FIRST FOUND HERE
2. PLEASE MAKE A CLEAN INSTALL EVEN THOUGH IF YOU ARE COMING FROM V22
CHANCES ARE YOU WILL BE FINE WITH A DIRTY ONE
3. I THINK THAT'S ALL- WHAT I DONT HAVE LISTED IN THE FEATURES MEANS ITS NOT SUPPOSED TO BE THERE
4. OH, THE 1ST TIME YOU BOOT POWER MODE IS ON- IF YOU DONT LIKE IT TURN IT OFF
5. THE FIRST TIME YOU BOOT IT MAY TAKE UP TO 10 MINUTES.
PLEASE BE PATIENT AND HAVE A CIGAR WHILE WAITING
6. ENJOY AND DONT BE A LEECHER

When i try to make calls its like the phone starts to lagg, and it tries to call but nothing happens... i can receive text messages, but not phone calls.. and when i try to send text's it takes like 20 minutes for the receiver to get them...
When trying to call my phone from a friends phone, normal beeps... but it just doesnt show up on my phone..
edit: It did show up on my phone, 2 minute's after i hung up.. It seems like my phone is delayed ALOT wtf!
in settings/about phone, do you see the correct baseband(modem) number you flashed ? could be a bad download ? did you flash via pc odin ?
