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

In some countries if you fix this successfully, you can go to jail, you know.
I might get banned for this, but if your device IS a N9005, go search around for "QPST". And even if you find what works, your phone most probably will always be set to "roaming", so your contract better has good rates. xD

When you flash gng1 firmware PHONE BOOTLOADER UPDATE and PHONE EFS CLEAR in odin must be checked !!! Phone efs is automaticaly recreated by android !!! after that Wipe data and factory reset only if you still not have your imei back but it must be there !!!
Same steps if you flash android 5(bl,ap,cp,csc)

That's the problem, as this is exactly what you'll have to do. xD As far as I've heard, only QPST can do the trick only on (obviously) Qualcomm powered devices.
Else, you've got a small tablet. xD

Baseband Bricked | SM-N9005

Kezedy said:
Hello xda users,
today i changed from customrom (cm12 nightly) to stock GNG2 rom on my SM-N9005, because the Official Lollipop Samsung Update release is near.
I started in TWRP with fullwipe and reinstalled GNG2 with pid-file & Nand erase all. After Stock booted up, my modem did not work as usual.
i decided to reflash the correct modem and only fixed sound etc, but not the mobile network. I tried restoring EFS partition in twrp and booted stock again, but nothing changed.
Now i flashed cm12 over twrp again, because i thinked it might be a bootloader issue caused by android 5. Also restored EFS after flashing cm12, but the simcard dont work. (yes i know how to put in a simcard correctly)
The EFS is also a correct backup from my phone. I had this issue 6 months ago and fixed it by releasing the batterie for an evening.
Anyone knows how to fix this?
Thanks, Kezedy

//EDIT
For all those who have the same Problem like i had, just flash this modem, which is a newer one then the GNG2 Modem.
Use CP-modem-XXUGNH1 from Androidfilehost

Flash full stock firmware for your device.

What they said.....
Flash the latest stock rom for your region - I mistakenly flashed the wrong one supposedly for the UK and had no network/unknown baseband/no imei! Found the correct one, flashed with odin and it fixed it asap

I wiped the whole phone with TWRP. DONT NAND ERASE ALL in Odin3!
Then i flashed the latest original stock firmware (GNG2) over Odin3 in Downloadmode.
You also need to hardreset after flashing! Then do your first boot. S´hutdown phone and flash the latest Modem via Odin3 in Downloadmode.
That is how it worked for me finally.

Yes, according to the info show in Recovery and also the info in the Phone INFO ★Samsung★, your phone should be N900T, not N9005. Please also note that the Back Sticker in your phone is FAKE, not a original one.
However you have flashed it with another rom/firmware, so now it is not necessary to flash back to its original firmware.
You can flash with a TMB firmware for N900T, or also flash with a stock firmware for N9005.
But don't forget to flash with a appropriate PIT file (with Re-Partition option selected).

Your PIT file it's for N9005?
On Odin v3.09 or 3.10 you can try flash the Modem in this way
Put modem file on CP
download PERSIST file (on attachement) and put on AP
and put your PIT file on PIT
check the box RE-Repartition
It work fine for me :fingers-crossed:

Yes please make sure you are using the correct PIT file.

okay I'll explain you
behind the battery there is a label that reads the version of your device
if GT-N90.... I think this is a copy of the note 3 I'm not sure
For me the official note 3 begins by SM-N90 ... (for exemple SM-N9005 or SM-N900T)
if the model of your device is not SM-N9 ... do not flashed rom Note 3 SM-N9.. you can brick your device
after you find the model of your device
seeking the appropriate modem or rom in preference for your region
and if possible the PIT file version your phone
when you have found all his said we

I have told you that the IMEI Sticker on your phone is a FAKE. So you cannot rely on it.

Null / null imei, unknow baseband

Hi, my phone is i9505, i have null imei and unknow baseband. I
was on 5.0.1 when i buyed, my misstake i dont verify the imei if is broke or not. Imei was /01
After that i flashed 4.4.2 ([email protected] with Modem_GNK2_FULL.tar and Bootloader_GNK2.tar) in hope imei will restore but neeh...., i dont have efs folder. Now imei show me null / null.
I have any chance to get imei back to use cellular network? If YES, are you kindly to give me step by step guide with download links?
Thank you all, i`m disperated

Hi,
You might search for a modem that from your region code. If you don't know your region code, unfortunately you should go to Samsung Service Center as you didn't have any EFS backup.

Flash modem from the region where the phone was bought. Since I couldn't find the package that only contains modem, you should download a full firmware. Grab it one from SamMobile or Samsung Updates.

It really has nothing to do with a modem with your region code.
You can use any modem it really doesn't matter.
Try flashing a stock lollipop firmware.

Well, let me explain more.
1- This phone was with stock I9505XXUHOB7 5.0.1 and IMEI was / 01, after that i flash [email protected] 4.4.2
1.1- I dont know if i can come back from stock 5.0.1 to stock 4.4.2, can you tell me if i can? I was afraid and i tryed with that repack rom.
After that IMEI was null/null with unknow baseband.
2- so i flash again that stock 5.0.1 and i have IMEI null/null with a working baseband.
Advices?

Unfortunately, you both should bring your phone to Samsung Service Center for IMEI restoration.

Here is a guide for downgrading:
http://forum.xda-developers.com/galaxy-s4/general/i9505-downgrade-5-0-lollipop-to-4-4-2-t3052472
If you still can't get it back, then a guy claimed this method worked for him.

If it's still not fixed then service centre.

http://www.sammobile.com/firmwares/database/SM-G900F/ choose your country and download the firmware.

Excuse me if I insist too much but my phone is bought in Germany but I'm in Romania and do not know which version of Android 6.0 to install not to receive error Ext4 in Odin ...

Try wiping cache or factory reset. Upgrade to Marshmallow also. Use SamFirm Tool to download Stock Roms.

I checked..for my region DBT latest firmware is 5.0 ...my question is : can i install the 6.0 from other region ? i've tried some couples of times but still got the ext 4 error ( some pit fle needed ) ..

My region code is DBT (Germany) and latest android version is 5.0 ..My question is : Can I flash a firmware (6.0.1) for another region without Ext4 error in Odin ? If yes , which rom ? Thx
