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 !!!!
Problem Resolved

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
hi basically i have a note 3 which was working fine i then done a factory reset in settigs and now it says baseband UNKNOWN and imei UNKOWN
ive read up on it and says i need to flash a stock rom via odin ?
im pretty new to this and i belive the rom i need is
EVR-N9005XXUGNG1-20141015154736.zip

i cannot download it anywhere ive tried everywhere a link or some help would be very appricated
thanks very much
Just flash a xxuene1.zip modem from recovery or flash a stock rom with xxuene1 baseband.
it worked for me.
Hi Guys.
I'm using Cyanogenmod 12 29012015 Build from Alberto96.
yesterday I went on and tried updating the modem to find a modem that will be more battery friendly.
my original modem was JKFND1. after i flashed XXUGNL1 I'm experiencing very weird issues like
NO DATA at specific regions or SPEED LIMIT of 25 KBPS.
when I tried to revert back to JKFND1 im getting no Reception at all, and on about device i get baseband unknown.
I also tried XXUGNF6 with the same results.
the only baseband that works is XXUGNL1. is it possible that XXUGNL1 baseband change something on my EFS ?
I tried restore to different rom backups I have with touchwiz UI.
and the results is the same. only XXUGNL1 works.
Any Advice guys ?
Flash original firmware with Odin maybe? I think it comes with stock baseband. Then re-root your phone and do whatever you want to do
Hello Friends,
Every time I flash a Custom AOSP based ROM i lose my efs,bluetooth address,imei.
But if I flash a Stock Based Custom ROM i do not have any errors or problems.
I have tried backing up efs and restoring it but no lock i have tried flashing the latest Lollipop Modem File.
If anyone has faced this problem please let me know the solution to it.
I am really frustrated with this error please help guys.

I wrote to you on the telegram channel also - the 910U has a weird modem (Intel) which has issues with the RIL (radio layer interface).
Also the developer has no phone note 4 910U so that he can test it and get logs to see errors.
As for all the peeps with this model - "It is what it is" - deal with it.

I'm not sure if this will work but you have a backup of your stock roms modem partition you could yry dirty flashing it to your custom rom. You could also use a root file manager and copy your stock roms csc files and place the in a flashable .zip and dirty flash that to your custom rom.

Opps , I mean rooted stock roms. I've noticed conflicts with custom roms if the rom manager has the same settings as GRX.

Your welcome, I was hoping it would have worked
Did you try creating a .zip with your working csc's and flash that in twrp as well?
