[Q] Big problem with my wifi - Galaxy S 4 Q&A, Help & Troubleshooting

Hello everybody,
I have a Samsung Galaxy S4 i9505 4G (with a Qualcomm SnapDragon S600) and I have a big problem with my wifi : It doesn't work, activation is impossible.
Last Avril, I flashed my device thanks to Odin with the firmware XXUFNC4 and I rooted as well.
Since that day, I didn't alter my device but wifi's problem appeared at the end of July.
So I tried many solutions :
- Many ROM : Samy S5 Deluxe, Google Edition, official's firmware XXUFNG8...
- Various Bootloader & Modem with new ROM.
- Various Kernel (AEL, GoogyMax...)
But the wifi doesn't want to activate...
Now, I have the official's firmware XXUFNC4 (flashed twice with ODIN + flash of PIT alone + last flash of XXUFNC4 with ODIN) and the problem is still here...
I have :
AP : I9505XXUFNC4
CP : I9505XXUFNC4
CSC : I9505XXFNC3
I hope this isn't a hardware's probleme because of Know Warranty 0x1...
Thank you in advance for your answers.
PS : Sorry for my english, it's not my native tongue.

But after the first and second flash of fix Wifi, I succeeded to connect a Wifi a few secondes.

Hello everyone! Any solution? I have the exactly same problem and would like to go back to BTU MD3 fw... I've been all night trying to downgrade with absolutely no succes. The only way my phone gets signal is in Siingapoore NE4. :crying:
Or if there isn't solution for doing downgrade, how can I flash ND3 PDA and NE4 MODEM at the same time?
Thanks in advance! (and sorry for my English)

You can downgrade AP only not the baseband flash full one package MD3 on AP and extract NE4 modem.Bin flash it in CP along with MD3

[Q] Need help wifi / stock ROM N900

Hi guys,
First I wanna say that I have samsung phone since a long time, if I post here that means I already search around xda and web to find answers.
So let me explain my situation :
I have a note 3 SM-N900 (not the 4G, not the dual SIM), buy here in China. It's a real one don't worry about that.
I wanted to update the ROM (from sammobile firmware) and here start the problems :
AP: N900ZSUDNB1
CP: N900XXUBMI2
CSC: N900OZSDNB1
I cannot find any ROM who match 100% on sammobile website ! The closest one is the one from Singapore. I dld it.
So I try to update with ODIN and fail.
I try many versions, but each time ODIN fail in the process.
Then my phone was stuck with the screen fail update connect to KIES etc... But of course this solution is not working (KIES 2&3).
And moreover my KNOX counter now is 1. I don't really care about warranty so that doesn't matter.
Then I try to use CF autoroot with ODIN and here sucess ! My phone was booting again !
But now I cannot use wifi anymore ! So I try to wipe data / cache...
Now Wifi is working but very slowly and each time I want to connect it asks me the password for the wifi.
I try to install Custom ROM but in in the bootloader my phone cannot see the sd memory...
So I am a little confused about all this version on Note3...
What can I do to update my phone with the lastest STOCK ROM (100% working) ???
Thanks
No one ?
Try flashing another stock ROM through Odin since you phone is booted up again. And make sure you have the latest Odin. I believe the latest is 3.0.9.

Dial *#1234# and you will see the CP (modem) don't match. Reflash (of the 5 files of the firmware android 5.0) only the CP via ODIN again.

1. Download and unzip this firmware on your pc: HERE.
2. Go to DOWNLOAD MODE on your device and flash via ODIN the .md5 file like in the pic attached.
3. Let the phone boot normally. Try if you have WIFI. Reflash again the same firmware if not.

[Q] no network on i9500

Hi guys..
my brother owns a galaxy s4 i9500 and he updated to 5.0.1 a month ago and he didnt like it as it had too many bugs and made the phone lag so he decided to downgrade .. when he down graded he lost his imei and baseband .. and had no network .. so he asked for my help i tried flashing a few kitkat modems but it was of no use then i rooted and flashed a custom rom then again i flashed a few modems but now it shows some other imei but when sim is inserted it shows that cant register to network .. so any help provided will be great ...
thanks in advance !
Same issue here, can anyone help us?
Flash the modem from a Lollipop ROM to get the signal back.
Attached the latest one from SER (Russia) Extract and then flash through Odin. Use CP or MODEM box depending on Odin version.

Base Band = I9505XXUEMJ5
Time = 2 years .
BEFORE Firmware = Android 4.3
AFTER Firmware = Android 5.0.1
**************************************
CHECK = *#1234#
AP: I9505XXUHOA7
CP: I9505XXUEMJ5
CSC: I95050XAH0A7
****************************************
Two days ago I was trying to update some latest version of app, As Whatsapp, Facebook, Messenger, youtube, y DI Radio. and play Marvel: Contest of Champions.
Later - The Wifi is OFF. or no work.
Yesterday.
1. Read all about problem wifi in many forums.
2. Test *#0011# and POWER SAVER OFF, WORK. but later 6 hours. WIFI NO WORK = FAIL
3. Download APP - Wifi Manager. WORK WIFI. but Later 6 hours. WIFI NO WORK = FAIL
Today
1. Install PhilZ Touch 6.58.7, - WORK
Use Odin 3.09
2. Install Android 5.0.1 Lollipop with wifi ---- see video https://www.youtube.com/watch?v=YN5RGpwSvDI
Firmware = XXUHA07-v1.1.zip
Lollipop 5.0.1 is Success and work perfect but NO WORK WIFI = FAIL
3. Finally, i got a another fix modem with wifi. --- I9505XXUGNK4_GSM_AND_LTE_MODEM.tar

somebody have a firmware original ?
Android 4.3 ???
PDA: I9505XXUEMJ5
CSC: I9505OXAEMJ5
MODEM: I9505XXUEMJ5
re-flash 5.0.1 again
somehow your modem is still old one (wasn't updated)
I had similar situation with "unable to turn wifi on" when updating OB7 -> OE3 (both 5.0.1, just new build).
It took me like 4 flashes before my phone finally grabbed modem files enabling wifi again.
Tried different Odin versions each time, forgot which one finally did it (possibly the one shipped with CF-auto-root)

Hardware failure. It's not software. If it was software then it just would not work at all.
Service center or let someone replace the wifi module.
Thank for suggestion, i will try go Service Center. or maybe i will change phone.
Also I did another option for change modem.
http://forum.xda-developers.com/showthread.php?t=2192025
I did it.
But, the baseband version, didn't change.
MODEM: I9505XXUEMJ5 to MODEM: I9505XXUEMJ7.
ODIN = PASS
Now appear I9505XXUEMJ5.
Well....

OK, i will do it ...
I did flashed 3 times.
Now im using Kitkat 4.4.2 Hele Rom v8.
I will test different version or lastest version Odin.
Hey what is OB7 ---> OB3??
target firmware was official i9505xxuhOE3 (5.0.1 xeo region - Poland, not branded, build from July or August)
forgot exact letter code but previous one was also 5.0.1 for Poland - just older build (March or April build OB7)
Sent from my TF300T using XDA Free mobile app
I'm having a similar issue
It started when I went Form Cyanogenmod 11 back to Stock 4.4.4
Every new method i came across would get it working for a short period of time then i would quit working again. I think ive exhausted the method of trouble shooting.
Method of trouble shooting thus far: safe mode boot, changing Wifi and bluetooth supplicants which worked for a period then deleted and booted in to safe mode which worked until reboot. Ive also tried numerous rom flashes both stock and custom along with modem flashes, short code and build.prop modification all to no avail
So this is what i believe I know. If I'm wrong if someone could kindly lead me in a direction of proof. I DO NOT believe it to be a hardware malfunction. For several reasons: 1. if it were a hardware issue would it simple not work at all 2. When using a stock rom every time i go to turn on wifi it tell me that some security measure is kicking in and no further action is required, but only for a brief second in using the back key to exit the message does it give my a list of networks around.
Which leads me to believe that its KNOX or KNOX related
I'm currently working with a Knox 0x1 9505
Is there any way to modify/add security credentials to by what ever might be the issue
