Baseband Unknown and no IMEI number

Hi All
I have the following error on my Samsung Galaxy Note 3 Exynos (N900).
My phone was rooted and Ive been running a custom ROM. Now I want to go back to stock but when I load any stock rom I get the Baseband Unknown and no IMEI number problem.
I have tried
* 4 different stock roms - same issue
* flashed separate modem driver - same issue
* restored EFS folder/partition - same issue
The only way I can get it to work again is by loading the custom ROM (http://forum.xda-developers.com/showthread.php?t=2503206).
Seeing as the custom ROM works and everyone says the problem is with the EFS folder. I backed up the EFS folder with Custom Rom loaded and restored the EFS folder with stock ROM loaded. Still the same issue - Baseband Unknown and no IMEI number.
I know there are a lot of posts regarding this issue and all seem to point to the EFS folder. Mine however doesnt seem to be a EFS folder issue.
Any other ideas?
Just FYI I also ran the KNOX warranty reset (not sure if this is relevant)
Thank you
Morne

Only thing that fixed my phone with that same issue was SPT box. Ask your local repair shop

I had unknown baseband and null imei yesterday on my N9005 after flashing stock rom using Odin. After 5 hours trying to find a solution I almost lost hope but then I tried flashing a other modem and it worked Phone works now and I have been using it all day.
The modem I flashed is CP_N9005XXUFNG2
I flashed it on N9005XXUEND5 (Nordic)
So my tip for you is to try find a different modem for your phone and flash it using Odin
Hope it helps

i am going to try now... i will inform you soon...
I could not select to thick phone bootloader update, during stock rom installation.
We have to find necessary files sperately to correct what we did wrong, and during normal stock installation damaged side does not rewritten that results still imei null and basband unkown (
1-) i try stock rom with pit files 718 and 805 eur open 32GB for N9005 but not fixed..
2-) Tried different modems on different stock or custom roms ...
Now time to find BOOTLOADER FILES TO INSTALL WITH ODIN )

Not sure this would help but have you tried a Factory Reset with clearing all cache's? If it works then try reflashing your stock saved ROM over it to regain all your apps.

Here is what happend.
The rom I was using before I got unknown baseband and null imei was N9005XXUFNF4. Note, this is the latest UK rom. I then flashed a Nordic rom that was available at that time which was N9005XXUEND5. Note, this rom is older and uses an older modem than N9005XXUFNF4. This caused unknown baseband and null imei for me.
The reason why I flashed in the first place was because I'm from Sweden and the new update that N9005XXUFNF4 had was available OTA on N9005XXUEND5 rom.
The latest Nordic rom that I downloaded from sammobile is N9005XXUFNG2. Note, this rom uses N9005XXUFNG2 modem, the same modem I flashed on N9005XXUEND5.
Problem now is that I can't receive OTA because it now thinks that I got the latest update already because I got the latest modem installed.
I flashed latest Nordic rom N9005XXUFNG2 today and everything is working fine now.

Thanks man.
I went from the stock rom that the phone came out with in South Africa to a Russian Rom (latest version) to a custom ROM. I came right by installing N900XXUENG1_N900ODDENF1_INS (India), it is the latest version available and it worked !!!!

My N9005 32GB story little bit unkown.
It is Stupid Story but i did not check original rom was 4.3 or 4.4.2 ??? Because i got 2 new phones from my friends to make root and install custom ROM. One of them was 4.4.2 rom that i was sucessfully root and install omega20 ROM. I suppose both phone was same and did not checked second one then when i was installing 4.4.2 CWM KK files with ODIN phone was freeze and fail !!!
I tried many stock roms and custom roms some recovery fix scripts etc. etc. Finally i start to use Mirek's method till adb commands... Last thing that i could not success to check Mirek's method is good for my phone... Last step was writing serial number IMEI no to dev block but i could not do it...Because of my adb knowledge nothing. I did many things blindly ) let me do try and see the results...
Let's forget about past. Please advice me what should i do now to try to fix the phone.
Final status is ROM installed stock SEE ROM and my CSC now EUR but still imei null and unknown baseband... AP:N9005XXUFNG2 , CSC:N9005OXXFNG2
I am sure that the phone info shows original CSC EUR, this phone was XSI. During the custom rom installation CSC was changed. ( sweet rom can change CSC code, during aroma installation asking to select CSC ).
Any advice ?
Thanks and Regards.

I have 6 different N9005 LTE modems 5 of them failed. now i am trying last one.
installing with odin two times with unthicked autobootloader as mentioned read one of the xda forum tread.
A question how can i know modem installed succsesfully because of unkown baseband phone info shows nothing !!!
is there another way to understand installed modem ?
i plan to install last E3 modem which was latest. i started from oldest to newest. on XXuFNG2 rom and csc EUR. if last one fail then i plan to follow mireks methods with adb commands. i was reading adb commands on android.com and viewed many videos on youtube about adb..
i am still working reading trying but still imei null and unknown baseband.

Same boat
I'm in the same boat as you guys!
No network, baseband, imei, nothing
I was on 4.3 MK2 XSI and flashed KK netherlands PHN stock ND3.
On first flashing, I got error "invalid ext4" on odin 3.09
Then I flashed the same ND3 with pit file and it passed.
Then this happened. no network, imei.
BTW I have EFS backup in .IMG backup which has that mc11.something file. But replacing that is of no use.
What do you guys suggest ? Can I flash NG2 stock on this XSI region stock ?
Will I require to use PIT file ?
Thanks

[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?
System info that may help:
Model Number: SGH-1337M
Android version: 4.4.2
Baseband version: I337MVLUAMDJ

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:

s4 rooted to factory rom?

HI was wondering if anyone could point me in the right direction, Im after putting my s4 9505 back to a factory rom. its been rooted.
Cheers Stu/

We might be able to, but you give us no information to work with. Please post the following information:
1. Model Number GT-I9505
2. Android Version, found by going to Settings > More > About device.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing Phone Info from the Play Store and running it.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No) Yes
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)

Cheers Stu.

The latest firmware for your S4 is here. Make sure you have the drivers from Samsung installed, then follow the instructions on that page to install the ROM. Be aware that if you have problems after installing the ROM you'll need to install it again.

Cheers for your help is there anywhere else to download from the site is a bit slow?
Stu.

www.samsung-updates.com, but I don't believe it's going to be any faster. After all, you are dealing with a 1.5GB download.

ok cheers I'll stick with this one its got 50 mins left

A big thank you for your help Strephon worked perfectly
All the best Stu.

[Q] Updating i9505 with firmware XXUDMH8

I tried to update the phone OTA but it says that its already updated to its latest version and i tried it on kies and it says that my device is not supported to update via kies. Im running my phone with android 4.2.2 jelly bean. I want to upgrade to kitkat because my phone drains battery faster based on my observations with my cousins phone, we also tried to change batteries just to make sure.
Is there a way to update this phone? I am willing to root this phone if thats what it takes.
Thanks

Please post the following information:
1. Model Number
2. Android Version, found by going to Settings > More > About device.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing Phone Info from the Play Store and running it.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)

1. GT-i9505
2. Version 4.2.2
3.Firmware Version
AP: I9505XXUDMH8
CP:I9505XXUDMH8
CSC:I9505XXDMHA
4.Globe
5.Philippines
6.No
7.No

From appearances the ROM that was installed was for a carrier unlocked unit. If the S4 is still tied to Globe that would explain why Kies didn't work. The correct version for you, based on the information given, is here. Flash it using Odin.

After that i can update the phone? Can i use Odin v.3.10.6? Thanks sir
By the way can i use different version like the international version?

1, That's the current ROM. If Samsung pushes an OTA update you should get it without any trouble.
2, Odin 3.10.6 is fine.
3. If your phone is carrier unlocked you can install any ROM you wish. However, you wouldn't get any OTA updates and Kies would report that the ROM and the device don't match. If your phone is not unlocked, it's not recommended to flash other ROMs and to stick with the ROM for your device.

How can i determine if its carrier unlocked? My phone can use other service providers here in the philippines, does that mean that it is carrier unlocked? Thanks sir

If you insert a SIM from another provider and can get service on the S4 then the phone is carrier unlocked.

If downloaded the version that you shared can i still use different sim card? If not can you send the link of the version that can be used by different carrier just to make sure? Thanks sir

Yes. Once you're unlocked, the ROM you install doesn't matter too much. Any SIM card should work in the S4.

1. Which version saves battery better the version 4.4.2 or 5.01? Because im just after the battery performance sir.
2. Can my firmware version be the reason why my phone sometimes cant detect my sim card and will be needing to restart my phone. Sometimes even i restart my phone my phone cant still detect my sim card so i need to restart it again. Is it a hardware or a software issue?
3.If im not satisfied with the battery performance of lolipop can i just repeat the steps you gave but instead use the 4.4.2 version provided by globe at the same site you gave?
Thanks sir

Help : Sim Card not available anymore ...

Ever since I've flashed a new CM rom today for my I9500 device, I always see that the sim card cannot be found. I see the icon on the notifications bar that shows that I don't have a sim card.
It could also be that I've flashed a bad modem, as I tried to find out how to overcome an issue that I kept having on roms, that the other person kept hearing himself twice.
I've tried flashing other roms (with wiping of everything except internal&external storage, of course), but it didn't help.
I've tried putting the sim card on another device (Nexus 5) and it worked fine, and I also tried to put a different sim card, and it didn't work on I9500...
Can anyone please help?

What happens when you install a stock ROM using Odin?

ok, I flashed an old modem, and it worked:
http://forum.xda-developers.com/showpost.php?p=58658207&postcount=2729
Sadly, the calls still have issues, but at least the sim card identification is ok.

I actually started to download it, and then decided to try an old modem first. it works. Sadly, I still have calls issues.
If you know which modem I should use (I live in Israel), please let me know.
I didn't have this issue on my previous device (I9300), and I really like AOSP roms. I hope I won't need to come back to TouchWiz just because of this...

Unbranded (ILO): I9500XXUHOI1
Cellcom (CEL): I9500XXUHOI1
Orange/Partner (PTR): I9500XXUHOI1
Pelephone (PCL): I9500XXUHOI1
These are the most current versions. If you look in the General forum, there should be a thread where the modem can be downloaded and flashed through Odin. If that particular version is not available, simply install one of the Isreali Touchwiz ROMs and the correct modem/baseband will be installed. Then reinstall your custom ROM.

How did you find this information?
Also, isn't what you wrote the roms, and not the modems?

Sammobile.com. A complete firmware package will consist of two strings of letters and numbers, PDA and CSC. The PDA string is also used to identify the bootloader and baseband, thus what I'm providing is just the modem.
