[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.

do you have a stock rom, are you root?
WIFI is kernel controlled , if you are root and have a custom recovery and have a custom rom you could try a different kernel ....
If in stock, flash again stock rom , maybe something went wrong during OTA

WIFI
My wifi was also off Until I found roms and fix from XDA
Now GT-I9505 is working great

Thank you for your time.
I don't actually have any idea about flashing or updating. All I know is that my S4 was okay until my nephew updated it to Kitkat. First I noticed that the mobile data is not working. I ignored it because I always use WIFI, then I also noticed my bluetooth isn't working as well. And recently the WIFI gave up too.
My nephew tried what he could like rooting, flashing kernel I think, modem wifi fix and custom ROM but nothing resolved the problems.
When I press mobile data, it turns green but there's no signal indicator,but if I put on another sim from another carrier (I'm in the Philippines by the way) mobile data turns on as I see signal on the upper right part of the screen.
But no matter what sim card or what carrier I'm on, the WIFI and bluetooth do not turn on. It also shows bluetooth and IP address unavailable.
Do you think this can still be fixed or is a hardware issue?
Thank you.

That's exactly what I'm downloading right now. I'm sorry I don't know what towelroot is. I like the S5 ROM, can I put it back after this procedure?
I'll let you know if it works.
Thank you so much!

Yes you can , but you have to start all over..root , custom recovery and then flash custom rom , towelroot is used to get root with out tripping knox warranty bit....but if you are going to flash a custom rom the bit is going to be tripped anyway if it was not already.

This is just depressing.
I downloaded the file twice but when I'm already unzipping it it says folder is empty. I tried to download it on my tablet as well but it always fails.
I don't know what else to try. If only I can just go back to jelly bean.
Thank you for your time anyway. Thanks a lot.

I am currently doing what you suggested but it's not moving anymore. I have been waiting for almost an hour now.
Here's what I can see.
It stopped on:
<ID:0/004> system. I'm. ext4
I'm scared to unplug it because my phone might not turn on again but it's not doing anything anymore!
What should I do?

Hi, I was able to complete the firmware update to XXUFNBE but its the same thing, no mobile data, no bluetooth and no wifi.
I put it back to XXUNGH8, same thing. I don't know what to do anymore. Is this a dead end for me?

Hi, I am having the same problem. For some reason I can't type *#1234* in the dialer (I can, but it doesnt do anything). My wifi stopped working a long time ago when I received official OTA to kitkat. I've tried flashing different kernels and roms, but no success. I tried flashing WiFi fix from the other thread, but it didnt work. BT and sound are fine.
ROM: 11-20141024-NIGHTLY-jflte
Baseband version I9505XXUFNC9
Kernel version 3.4.104-cyanogenmod-g52b4b50
I was thinking about flashing bootloader and modem+non-hlos XXUGNH8 from http://forum.xda-developers.com/showpost.php?p=50965837&postcount=2627 - might this help?

Hi..im maybe late but my i9505XXSHQB1 5.0.1 Also have wifi and thetering problem..how cam i fix it

[Q] Kernel issue or bricked?

Yesterday I tried to upgrade my Galaxy S4 (Canadian, Telus SGH-I337M) to lollipop. I came here and installed the latest Cyanogenmod successfully using the posted instructions. Unfortunately, BlueTooth wasn't working so I decided to uninstall it.
I then thought I'd try CM11 via their auto installer. After taking the phone back to factory settings, I ran the CM installer and got CM11 installed instead. Except with that, my phone lost all audio. No phone communication, no rings, nothing.
So I tried going back to stock and I downloaded and installed the 4.4.2 stock ROM... expect now I have no wi-fi functionality, and a couple of other weird behaviors like very, very slow screen response.
The most likely answer I've found is that somewhere in this process, I flashed the kernel and now my kernel is incompatible with my ROM. I've found what I think is the right kernel, but I can't install it. All of the instructions say to use ODIN, but ODIN restricts me to putting specific file extensions in the box, but these files come as .RAR or .ZIP, and the contents of the archive don't have any of the allowed file extensions (i.e. .BIN files).
At this point, my priority is just getting a working phone again by any means necessary - I don't care whether it's a custom ROM or not, I just want functionality on all of my phone at once! I'm not computer illiterate, but at this point I've outstripped my troubleshooting capability.
Help?

Try installing the stock ROM a second time over the top of your first install of the stock ROM. For some unknown reason installation through Odin doesn't always result in a perfectly functioning device the first time around. Installing the ROM a second time however tends to fix things.

Did you download your stock firmware from sammobile.com?
The firmwares from that site should work fine in Odin.

I've gone through a few stock ROMs. The one I'm working with now seems to be the right one. It's I337M_TLS_I337MVLUFNI2_I337MOYAFNI2_Original.zip
SamMobile says those are the right ones, and I have installed it over itself... repeatedly!
I've done more trouble shooting now and I have issues regardless of what ROM (CM12 or stock 4.4.2) I install. The issues between the two are different in some regards but in either case, the phone is more or less toast!
- Phone calls are VERY slow to respond in both (when I try to make a call, even though I know I have no audio capability).
- No audio at all
- on Stock 4.4.2, no wifi
- Screen is slow to respond on stock, particularly when dismissing the lock screen.
- On CM12, Bluetooth and wifi can't be enabled simultaneously
- CM12 won't play videos (didn't try on stcok)
What have I done?!

Update:
Using a different file recommended by Sammobile (they have more than 1 listed for this phone on their site), and DLing it directly from them , I seem to have stock functionality back. Yaaa!
The most recent ROM (ending in FNI2) didn't work but when I went back to a build about 6 months older (ending in FNC1) that one worked out.
I guess the question then remains: What went wrong, and is there a ROM that should theoretically work for this phone?
Thanks!

You are flashing wrong CSC maybe. Solution:
1. Verify your CSC. Use this APP for know your real CSC. (Pic 1)
2. Go to Sammobile again and download the correct and latest firmware for your CSC.
3. Unzip and flash that firmware via ODIN.
4. Dial *#1234# and tell me what appears :highfive:

1. CSC shows:
Original CSC Code: TLS
Firmware's CSC Code: TLS
Active CSC Code: TLS
CSC Country: Canada
CSC Country ISO: CA
Product Code: SGH-I337ZKATLS
2. After a couple of OTA Updates overnight, the phone is now using firmware I337MVLUFNI2, which is the one I tried from SamMobile that failed, so I had to use a six month older build. which worked fine for some reason.
3. AP, CP, and CSC all show I337MVLUFNI2 now.
I'm now very reluctant to try any custom ROM on this phone after spending 30 hours worrying that I had bricked it! I tried about 5 different ROMs throughout this process that all had varying degrees of that same issue. Is the Canadian S4 SGH-I337M that much different from the i9505? Did I just screw something up royally? I'm happy that my phone is working now, but I'd still like to know what went wrong, or whether customs ROMs are an option for me.

Yes,
That seems to be the case, but should I have been safe in trying to install a custom Lollipop ROM? I'm kind of in a 'once bitten twice shy' state of mind now. I'd like to go to 5.0.2 but after this, I'm not so sure.

How you wish. But remember that Lollipop stock firmware for your device is a leak still or you can try with different custom roms. You will have BUGS. If the device was mine I will wait for the OTA updates but it's only my opinion. I'm not desperate for Lollipop :highfive:

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

How can I return to stock firmware from CM 12.1 (Android 5.1)

Hi,
My Device is:
SM-N9005 LTE (32GB)
It was running 4.4. Kitkat and I tried to flash Android 5.0 via Odin. Everything went fine except wifi which did not turn on at all. While searching I found out that many users faced this and there isn't a best fix available yet. Probably I flashed a wrong firmware which may have caused some csc mismatch or kernel issue. I definitely needed the wifi back so i went on to try and experiment more on the device which brought me to CM 12.1 and I flashed it via TWRP. It brought back my wifi but now i miss some of my staple apps on this device especially S Pen Stylus & S health. I tried the simple method - downloading a firmware from sammobile and flashing it through Odin but it failed in Odin. Is there any way I can go back to to Stock firmware? My knox is at 0x1 but it doesn't matter much.
Thanks a lot in advance.

My knox is at 0x1 but it doesn't matter much.
Thanks a lot in advance.

Hi,
I already tried that but it gives this error.

Maybe you have updated your bootloader that's why you can't downgrade. Try lollipop roms. Or try a tw based custom rom with twrp.

What is the baseband and bootloader on your phone?
Match the last 4 characters to firmware here: http://www.sammobile.com/firmwares/database/SM-N9005/

I'm sorry for hijacking this post, but something fairly similar happened to me.
I've got an SM-N900, decided to update to Lollipop but despite all my efforts I've been getting awful battery life so I'd like to go back to KK.
Right now I'm using
Bootloader & PDA: N900UBUEBOF1
CSC: N900PGUEBOF2
Baseband: N900UBUEBOC3
and would like to go back to
PDA: N900UBUDND1
CSC: N900UWADND3
I've been reading and found that you need to flash this if your bootloader is on Lollipop, this is where my doubts begin. How do I know if my bootloader has been updated to Lollipop? If my BL is on Lollipop and I flash that file, can I install any KK rom?
Thank you for reading this, and I apologize for hijacking this thread.
