Wifi and sound problem

Hi, i just got myself a Samsung Galaxy S4 and i have succesfully flashed several roms. But when i flashed back to the original firmware with Odin, suddenly my WiFi can't be enabled, and my speakers don't work. I have tried factory resetting, and a full wipe, but it didn't work. But when i use a different rom, the wifi starts working again.
if anyone could help me it would be great

known issue with MJ5 stock firmware, is this what you have?
Flash one of the Wifi Fix modems here with Odin. Make sure that the one you download matches the firmware you are running.
Hope that fixes it, if it doesn't work first time, flash it, restart phone back into download mode, and flash again. Had to do that with mine.

No, im sorry it didn't work for me, not even the doubleflash thing
I should probably just send it in on my warranty

[Q] GS4 - How to return completely stock for warranty exchange

Hi,
I've been do many flash last 24 hours on my Galaxy S4(Model SGH-I337M, Telus). Initialy, i've the factory stock rom, rooted. So, yesterday, i've decided to install Cyanogen mods nightly on my phone. Not the first time i've been used it on my phone. No problem before. So, this night, after a friend show me the release canditate release seem to be more stable, i've been try to put it on my phone. So, accidentaly wipe all the data on my phone. When i'm back home, i've put again the samsung original rom from my operator(4.2.2), found here, on the website, whit odin. All completed succefully, but i've noticed that the wifi won't turn on after the flash, and no sound from the speaker. So, i've put Cyanogen nigthlies again to test if it rom relative, but same issues here, no sound, but the wifi was working. The phone was very instable, so. Then, finaly, put the original rom again, without any rooting. Stuck on samsung logo, that i've finaly got fixed by clear the data and cache. But, no sound, and no wifi. Instable too.
Precision about phone: Unlocked whit the service mode(work), and enabled AWS whit a software and file(tutorial found here)
My question is: Anything else i can do to make my phone work fine again, and does it's possible to make the phone totaly stock? When i boot up, i've noticed that the phone, whit all rom i've try, said on samsung logo: Kernel is not sendroid enfonced, warranty status: kernel, so i can't go to return my phone on warranty whit that. How i can erase that line, and make my phone seem to be no modified?
Just to specify, it's not the first time i flash a phone. Do many flash, whit galaxy s2, s3 and s4, and sure, mine. Got try Cyanogen, stock, know how Odin work and all, try many rom, and before today, never has any problem to do turn back, but now, it's seem to be impossible.
Thank you very much for your help, very appreciated!

I would flash the stock firmware with odin again. After flashing do a factory reset in the stock recovery.

I've just try this. Flash the stock rom whit odin, and factory reset on original recovery after. Same, no wifi, no any sound.
Just see yesterday, when i'm flashing, i'm flashing on the bootloader in odin(whit the tar for the stock rom). Today, correct this by flash on the pda section, still not work. Found here on the forum the stock bootloader, rom, csc, and modem, but when i do this whit odin, odin said fail.
Thank very much, i think my phone is dead, and nothing to do to exchange it on warranty.

I think Kies has an emergency firmware recovery mode.... maybe that'll work.

Just try this. Kies is the worst software i've ever see. The software completely freeze random. When i go to the emergency menu, never, kies recognize my phone here. I've tried to plug my phone, no recognized. Tried without plug it, no recognized. When i plug it, kies said connection in progress, and can stay here 30 min.
I'm a idea of what is my problem. Before do install of cyanogen, i've been applied the samsung official 4.3 update, whit knox. And, according to what i read on many forum, knox is not ereasable, So, it's completely freeze my phone, and nothing to do.
Anyone have the factory telus bootloader and other factory stock items because i want to put it stock.
Thank.

Finally get problems fixed by take the TELUS stock 4.3 ROM and flash it whit Odin. After, can flash cyanogen nightlies again and the phone work well again.
Whit the stock ROM, didn't see any line on the Samsung boot logo that i've rooted. After root this appear again. Knox regardless of ROM installed said 0x1.
If anyone have a fix to put it again 0x0 very appreciated otherwise the phone work fine and thank you very much for your help.

@Spacemonkie4207 never my itune was freeze, and i can do basic operation like transfer music or create playlist without any problem. My kies stay on connection in progress, and turn, turn, turn, but never connect. And when it connect, only one operation, and kies completely freeze, stop responding, need to close it, and open it again. Tried many cable, usb cable, reinstalling software, two other computer, but nothing to do.

I recovered back to stock from custom to 4.3 however if you do so, depending on carrier you could lose root and the ability to install custom recovery.
I would revert back to 4.2.2 (as it's knox free) go to samsungupdates (google it) and pull the 4.2.2 for your region and carrier. flash with odin 3.9
you'll lose root, but you can always perform again as long as not on 4.3 (with 4.3 u can still root if you remove all the knox stuff, u just lose warranty).

No Signal after 4.4.2 update

Hey Guys,
Today I updated my i9505 from Cynogen Mod 10.3.1 to the new "[AOSP] Official 4.4.2 - S4 Google Edition - Final-R1.1" by Jamal, but I read that you needed to update to the leaked 4.4.2 before flashing so that the modem and bits are upto date before flashing any 4.4.2 ROMs or else you could end up with no wifi after flashing.
So I followed these instructions to flash the leaked 4.4.2:
INSTRUCTIONS
- Extract (unzip) the firmware file
- Download Odin3 v3.09 (From here or here)
- Extract Odin .ZIP file
- Open Odin3 v3.09
- Restart phone in download mode (Press and hold Home + Power + Volume down buttons)
- Connect phone and wait until you get a blue sign in Odin
- Add AP_I9505XXUFNA5_373648_REV06_user_low_ship_MULTI_CERT.tar.md5 to AP
- Add BL_I9505XXUFNA5_373648_REV06_user_low_ship_MULTI_CERT.tar.md5 to BL
- Add CP_I9505XXUFNA5_373648_REV06_user_low_ship_MULTI_CERT.tar.md5 to CP
- Add CSC_OXA_I9505OXAFNA5_373648_REV06_user_low_ship_MULTI_CERT.tar.md5 to CSC
- Make sure re-partition is NOT ticked
- Click start button, sit back and wait a few minutes.
Which all went well but I couldn't get Wifi after flashing, and (probably not important) but the default language it choose during the setup was Dutch??? Seeing as I couldnt get the wifi to enable I decided to flash Philz Touch Recovery v6 and then put Jamal's "S4 Google Edition - Final-R1.1" by putting it onto the SD card and flashing through Philz recovery.
Flashing went without a problem.... only thing is now I cant get Vodafone (UK) signal 80% of the time, the other 20% I do get signal and can make calls, just seems strange as previously 80% I WOULD get signal!
Did I do something wrong? I had a really bad feeling that flashing the CP, BL and CSC has somehow messed things up......please help!

Same problem, bump.

I just fixed the problem, ColdIce23, check your Baseband Version under Settings > About Device, I bet yours is still set to the original baseband version like mine was...
1) Re-Download the Baseband for the leaked 4.4.2 rom (Here)
2) Open Odin 3.09 and do the following:
Ok it worked.
If anyone else is having issues with the baseband not changing, do this.
Use Odin v3.04
Untick Autoreboot
Flash modem
Reboot once again into Download Mode using (Vol Down plus Home button combi)
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.

Now I have FULL SIGNAL! .....so far..... will report back once I have left work but this is a good sign as I had no signal what-so-ever 5 minutes ago!

Flasing a 4.4.2 Modem works well with the Kit Kat based roms. Two to choose from NA1 or NA5, depending on what bootloader your on flash the appropriate modem files.
I've got NA5 on the 4.4.2 GE Rom with Three and no signal issues as of yet.

I think u missunderstood something. For the Kitkat Google Edition u do not have to flash the leak before. Its only for the Samsung Touchwiz Version of Kitkat

I flashed the NA5 modem which seems to have failed the first time round, as it didnt actually change the baseband version in settings. Since flashing a second time (when it actual flashed properly) I now have full signal...... but I have another problem now:
When I click the dailer and select a person to call, the screen goes black and I dont see/hear any indication that a call has initiated. I tried with my wife and her phone rings and she can answer the call, but my screen is still black with no sound....
I have tried wiping data / davlik / cache and installing the rom from scratch, but I still get the same issue?
UPDATE:
Right so I just flashed CM11 as a test, and still can't make calls, so obviously not a ROM fault..... does the BL, CP or CSC have anything to do with the making calls procress?

I've got a similar issue.
I've got a M919V running Jamal's 4.3 GPE rom, but after flashing Jamal's 4.4.2 GPE i get no signal. After going into settings and selecting network the signal lasts, but after the screen goes off signal is once again lost.
Is there a procedure to follow that will fix this? This is found when when flashing many 4.4 roms.
-Thanks

Well, I get signal when I'm near a cell tower...
No changes tho. Still same problem.

Hi guys,
I'm wondering if you have resolved your modem problems?
I flashed to Jamal's 4.4.2 version 1.2 and I don't have a signal now.
I flashed the modem to NA5 but styill no signal. Also I can't even check my CSC using *#1234# as "Mobile network not available"
Any suggestions?
Thanks.

Hi Duskin,
For me, I think it's releated to the phone itself as I got a screen replacement. I haven't solved the problem yet because I got to get back to the store where I got my screen replaced.

Problems going back to stock

Hi,
Was running CM11 on my GS4. I want to go completely back to stock however I'm hitting issues with it.
Downloaded the 02UK firmware file from Samware, flashed it in Odin, did a wipe before and after. Takes a while to boot in each time, sometimes needs a battery pull etc.
Now, I can load up fine - however no matter what I try, wifi won't turn on, a lot of the time signal will drop/ turn off when I lock the screen. Have tried flashing 4.2.2 as well, exactly the same and on the latest flash noticed as issue with the recovery, won't allow a data wipe/ partition in recovery, just flashes something red and then reboots.
I know this has probably been asked a milion times before. But hoping someone can help me get back to stock without the issues!
Thanks in advance.

Sent from Hell ?

Currently 4.2.2 as I read the 4.3 update had caused some of these issues (although I want to be on stock 4.3.
I did notice after I posted that the baseband was for German phones (no idea how that got on there). So I flashed the a new modem and baseband is now at I9505XXUEMK8 which is supposed to be the correct one (if not please advise!?). However Wifi still not working. Tried the wifi fix file for the baseband, didn't work, also tried the root /data/misc/wifi/wpa_supplicant rename fix. Didn't work.
Are you able to tell me which Stock Rom/ Modem etc to flash or anything else to try??
Thanks in advance!

Try to find the right Stock rom from here that base in your country mate and flash it via odin . Like i told you if you boot into download mode and check if there is knox void warranty? If you dont have that flash inly 4.2.2 stock rom but if you see that then feel free to flash a stock 4.3

Ok - So I have flashed the UK 4.3 BTU rom (Jss15J.I9505XXUEMKF) and have a baseband of I9505XXUEMK8 (which was the O2 one). Signal is fine no issues etc.
Still Wifi won't turn on though.
What do I need to do for this bit??
EDIT: As per your last post, I have no idea about Knox? I didn't see anything show up on download mode.
It also doesn't seem to be working now. The rom crashes when calls are received and wont dial etc. Ok - so should I go back and install the earliest 4.2.2 Rom version for 02 as the phone came with? Then update through OTA?

Well I told you if you dont have an Entry of Knox Warranty Void when you boot into download mode then flash the 4.2.2 Stock rom :S But you already flashed the 4.3 so you can no longer downgrade to 4.2.2 ... Can you please Dial *#1234# and write it down somewhere . and then Download this Wifi Fix and flash it Via odin and After reboot still did not work then Try to download and extract this file and Flash the .tar Via odin by selecting Phone/CP And if this file did not work after flashing then please feel free to play one of the wifi fix from Here Start's from MK9 until MKE might fix your issue.

Thanks for the help Repulsa. Will try that shortly and let you know the results!
EDIT - What about the Rom issues itself? I haven't had a chance to test everything, but I can't make calls. It calls the person but the screen freezes blank and then flickers. Should I reinstall the rom first or use another?

Tried everything from you earlier post except going through the final wifi fix versions. Nothing has worked so far though....

I'm in pretty much the boat.... I was using Omega ROM 4.3 but wanted to go back to Stock unrooted firmware.
I flashed Stock 4.3 (XXUEMKF to be precise - both Baseband and Build) using Odin 3.04
Now I cant turn wifi on
When I go into Download mode I dont have any KNOX lines and my Binary is Custom not stock!!!
Don't want to mess things up anymore than I already have by trying to flash everything under the sun!!!!
Back to using my faithful Note 2 for the time being then I guess!!!

Are you flashing the latest stock ROM from sammobile.com or updato.com?

I ended up using the pixel experience rom. I am sure I have the wrong bootloader and modem for i337m though. It works with data when I reset network settings and re-enable. Data each reboot. For the longest time lineage 9505 ROMs worked until like Feb 5th I saw the data just fall use just fall off. I couldn't get chatr to work anymore. It was a nightmare I went to stock and , pitted the phone and it would only function until I added TWRP and tried a nougat rom or even with latest modem. Wifi was evn a problem. Now I am using like a lollipop bootloader with the green battery charging and modem isn't right. When I flash a different modem and bootloader in Odin and rip the battery and then cableit doesn't even change .
Wtf?

I'm not sure how you could flash the wrong bootloader unless it was flashed using TWRP or CWM. To confirm, boot into download mode to see the model # listed on the screen.
Are the modem and bootloader matched; i.e. the phone is running a 5.0 bootloader and modem? To easily ensure that both are matched, you can flash the latest stock ROM using Odin.
If the modem version is not changing after being flashed, it is possible that the internal memory is faulty.
