Try flashing just the latest modem. And then keep the phone off for a few minutes. (Uncheck autoreboot from odin while flashing modem)
In addition are the baseband version and imei number okay?

As the gentlemen said above, it will just be the modem. It seems like your friend has flashed a new rom, possibly 4.3 or 4.4.# and hasn't got the correct modem. Tell him to search on Sam Mobile for the correct modem for his device numbers and flash it via odin, again as stated above.
After all that, it should be fine!

the thing is, he doesnt know how to flash roms and this stuff, and he had the 4.2.2 stock, i flashed the 4.4.2 stock....but doesnt the rom contain a modem??

It does contain. But separately flashing modems and keeping the phone off just after the flash does magic at times.
Uncheck autoreboot while flashing via odin.
If you're flashing the recovery flashable modem, flash and then tun the phone off and pull the battery out.

ill check when i see him...thanks guys

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.

[Q] S4 wi-fi not active after update

Hello, it is 1 month that I bought the s4.
Until recently, no problem,
but after upgrading from 4.2.2 to 4.3 gave me problems to wi-fi..
wi-fi does not active,
I press to activate, but not active.
I already tried to do the factory reset but nothing is not working
pleas help me....!
IM ITALIAN :crying:
Have you flashed any custom roms on your device? Also what version is your S4? (I9500,9505...)
Sent from my Galaxy S4 with 4.4 KitKat
Remove battery for one minute and insert it again, go into download mode, then flash your firmware again. If this will not help then you must flash wifi fix for your rom revision (it is simply modem files only). sometimes when flashing 4.3 modem files do not stick/flash thats why your wifi is not working, you can check if it is true in system info where modem version is shown, if it is different than flashed firmware... thats why wifi is not working).
If helped please click thanks

[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).

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.

Your having a signal issue because you need to flash a diffetent modem mate. And that should fix ur problem on signal issue . Do you mind booting into download mode and check if iy say the entry knox warranty void. Thanks
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?

IMEI is the same, except for an extra /1 on the end?? Rest as follows;
AP I905XXUEMKF
CP I9505XXUEMK8
CSC I9505BTUEMK5
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!!!

Galaxy S4 Wifi Won't Turn On

Galaxy S4 - i337m - Android 4.3
Okay, so here's my problem.
Today in the morning after I woke up, I checked my phone and it said it had downloaded a software update. It was just a complimentary update for 4.3, it said bug fixing, etc. in details. I clicked accept and the installation started.
After this, all crap started to happen.
The Wi-Fi NEVER worked again, everytime I clicked the Wi-Fi widget in the notification bar, it turned green and immediately switched back to gray. It also didn't work when trying to turn Wi-FI on from the settings menu.
I tried everything, the battery pulling, the thing of disabling the Wi-Fi energy save, and nothing worked. It all pointed to a factory reset.
So I did all my backups (My S4 was rooted), and finally made the factory reset.
After this finished, I did all the starting configuration of the S4 (like when it was brand-new). Then, I tried to turn on Wi-Fi.
Surprise, surprise. DIDN'T WORK.
I'm so desperate right now, I don't know what to do.
I'm currently downloading 4.4.2 to flash it via Odin, and see if this works.
Any help, please?
Flashing the 4.4.2 ROM you're downloading now should definitely fix the problem. I know that in some instances, us I9505 owners have to flash a stock ROM twice through Odin before the modem will function. It sounds like your software update broke the modem in this fashion, which is why the ROM install you're planning should fix it. Be aware however that installing KitKat will give you Knox if you don't already have it.
