[Q] [I9500] Have generic IMEI and not able to connect to network

Hi,
I had installed the CyanogenMod 10.2 available in the original android development section on my I9500. I flashed it in the morning. everything was working fine except camera till afternoon. Suddenly on afternoon i observe that my phone has entered into emergency signals mode and was not connected to my mobile network. First i thought it was signal problem but upon reading found out that it is IMEI getting changed problem. I have installed Stock ROM again to try if it solves the problem but sadly it doesnt .
Anyone out there faced the same issue and can help me?
Thanks

I have an Indian model I9500 . I tried flashing Omega Rom before trying CM. For Omega ROM i flashed XXUBMG9. After that i flashed back the Stock firmware I9500XXUAMDE_I9500ODDAMDC_INU. Then i flashed CM. CM worked fine for half a day. Then it failed connecting to my network.
With the method you are telling i flashed my stock firmware modem first, but it didnt work. Now i flashed XXUBMG9 and it worked.
Can't i go back to my stock firmware modem now? Am I stuck with this modem ?

you still on the first old firmware for India (MDE).
you can take ota update and then the modem will be replaced. or flash latest Indian firmware (MG5) and you will be on full stock.
PS. i guess that modem does not affect warranty.

MEA firmware came with DDUBMEA modem. try to flash this modem alone as "phone" twice http://d-h.st/c9i
any way these are all INS firmwares http://www.sammobile.com/firmwares/1/?model=GT-I9500&pcode=INS#firmware

I tried flashing MEA modem twice all other Indian Modems twice and nothing worked. It is only working on XXUBMG9 modem. I am really stuck on this modem.
Does anyone has a theory of why this is happening? Omega ROMv14 wanted flashing this modem as a prerequisite. I had flashed this modem before flashing Omega. Then i went back to my stock and flashed CM over my stock ROM. CM wasworking fine till sometime , then it started to drop the signals and later i realized i lost my imei. If i flash back the MG9 modem the i get the proper my phones imei and network connects. But for all other modem of india it just shows the generic imei and doesnt connect to network.
Can anyone help me postmortem this case and tell what went wrong where?

all failed

A few questions about getting back to stock
My device is curretly like this:

Knox 0x1
TWRP recovery

I would like to return completly to stock. I know I won't be able to be Knox 0x0 again but I want the stock recovery, kernel and ROM.
My question is: can I simply restore the firmware in Kies to get back to stock (including the recovery)?

You can try, but I doubt that Kies won't let you back to stock since your recovery has been modified.
The easier way is using Odin. Download full stock firmware for your device, and flash it via Odin. No data will be lost.
You can use Phone INFO ★Samsung★ app > Menu > 'Firmware Browser' to find and download the correct stock firmware for your device.

i am unable to get the official firmware for my note 3 SM-N9005 whose Baseband version is N9005XXUGBOJI and Build number is LRX21V.N9005XXUGBOK6 so please help me find the official firmware and its stock firmware

Baseband is modem not firmware .
Go to sammobile or samsung-updates and find your model .
Select your country and network .

go to http://www.sammobile.com/firmwares/database/SM-N9005/ and select the country of the mobile and if u dont know it then download a app called Phone INFO *Samsung* from the playstore and go to the CSC code tab on that app and look for the original CSC code field (it should be a 3 letters or something) and find that code in the link above in the country selection field and download

32g sm-n9005 baseband unknown/imei null/sound and camera not working

After flashing the sm-n9005 to N9005DXUENE4 the phone is not function at all. Though I can still boot into the system it becomes very laggy, baseband unknown, imei null sound and camera not working. Did try to flash Sweetrom V7 still the same. Anyway if there's a way I can bring it back to life?

Try to flash back stock rom..or restore thru kies 3 will be much better..

IMEI NULL/NULL is modem or hardware problem
My guess is that it is due to a modem/firmware mismatch. Start flashing a modem for same fw version.

did that already, one more thing the phone keyboard and the swipe to unlock is not responsive at all.repair.

did you find any solution and fixed your phone ?

When arrive the problem and which rom and modem do you have before?
You need to go back on this... you Don t have efs backup?????
Otherwise try to put NF2 modem with NF4 rom. Bootloader is not important.
But check if modem well installed because odin says PASS but still on old modem

Try to flash latest NG2 firmware after whipe cache and factory reset. It did the job for me.

I have been already try KHIZAR'S METHOD*to install different LTE Modems on my phone with different stock roms. No matter finally i gave my phone to local repair shop. Samsung Official repair center's do not care about my phone due to it is N9005 and it is not for my country selling phone.
And another question my first N9005 slept in water during almost whole night. When i wake up in the morning i found my phone in water since many hours. I give it repair shop to check also but seems to main board needs to be replaced. Connection sockets damaged badly like melted half of them. is it possible to only change the connection sockets instead of whole mainboard ? Any idea ? and Where can i get only the connection sockets ? from samy ? ))
And i am starting the googled to find N9005 mainboard sockets

You re the terminator of N9005.? ....... no idea about motherboard or connector sorry....

I am having the same issue,
I'm new to the site been cool so far learned a lot and done a lot with my Note 3 since being here.
I recently rooted and install a custom rom (N900_NF3_INU_Dr.Ketan Custom ROM K11) that works great, I tried flashing back to stock but encountered a major problem. after flashing to stock my IMEI is unknown and also my base-band from reading it seem as if my EFS got corrupted tried a ton of different thing and still I cant get this to work on stock. Only way my IMEI and base-band comes back is whenever I reinstall the custom rom (N900_NF3_INU_Dr.Ketan Custom ROM K11) and restore the EFS that was backed up during the first installation of this rom
Thanks in advance all help is greatly appreciated. :good::good:

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 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 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

Maybe you will need a Z3X box.
But first try others stock roms of different countries and different Android versions.
