Galaxy note 3 sm-n900 Unkonwn baseband

hello Guys, i have a galaxy note 3 sm-n900 on my hand right now, the problem is that i have no data, unknown baseband and no imei (Null/Null)......is there any solution ??? thank you...

In normal case all this missing comes from factory, if you need help from others you must explain how this happened, what rom you are using etc etc

May be your imei data was corrupt.
Did you make backup for the EFS data?
If so just restore it.

i have the same issue with a friends phone, no EFS backup, he won't tell what he did to the phone but now imei is null/null and doesn't have a baseband, anyway to fix it?

similar problem
I have a sm-n900 exynos and I have lost my imei and baseband during a Samsung flash. I have a TWRP backup, efs.img backup by dr.ketan's backup tool but nothing is able to restore my efs. I have scanned emmc blocks for bricked blocks and all blocks come back as non-corrupted. may be the partition is corrupted .how do I erase my efs partition to rebuild it. I have tired to flash PIT from ODIN but that too doesn't work.
tried this post http://forum.xda-developers.com/showthread.php?t=2567133&page=36
but need a guide to identify the partitions and how to rebuild them. by any chance anyone know if I could extract twrp backup to files to restore efs or from efs.img so I can use the nv_data.bin, since tried restoring the backups and it didn't restore I feel the partition might be corrupt and hence not being re-written. so might be I have to rebuild the partitions by formatting as explained in this thread. but I don't know exactly the steps for exynos variant. I tried using terminal on twrp but mkef2 command shows mmbcblkp03 doesn't exist which as I have read in posts is the efs partition on this phone and reboots to twrp recovery. and mmbcblkp12 show filesystem too small and reboots to twrp recovery

weird thing is, i sometimes find the imei and the baseband and sometimes i dont, phone's not rooted yet, trying to find a way to root it without trippong knox since is not mine, but maybe im able to recover the efs i hope it works

Same problem here...
Hey guys, I'm experiencing the same problem since i installed VN kit kat rom. I searched for the efs backup and i found it but when i use odin to flash it it doesn't work. I tried flashing back to stock but that doesn't work. Can soneone please help me?

Fixed it!!!
If you have a n900 and your imei is null and your baseband is unknown all you have to do is to flash the file beneath with cwm recovery and voila!

HI just one question my friend has the exact same problem (IMEI null/null) baseband is unkown !!! the device is SM-N900 running 4.4.2 right now he flashed the file but the problem still exist !!! pleeeeeeeeease help !!
this file only works if the device is running official 4.3 ??? or we can flash it on stock 4.4.2 !!!
it seems wiered to me that others on this forum flashed the file and it worked with them !!!!!
pleeeeeeease help

You can still flash it if you have 4.4.2. The file i uploaded to be flashed is just to flash the baseband not the rom itself.
Btw did you flash the file with cwm recovery?

Thanks man for the reply
anyway !! yes of course we flashed the file with CWM recovery tha recovery that we used is ( n900-cwm-recovery-6.0.4.7-kk(0125) )
we flashed it 2 times but nothing !! after flashing the baseband stays unkown and IMEI (null/null)
just one thing that the system is 4.4.2 rooted is that a problem ? should we flash the official stock 4.4.2 and then flash the file ?!!
we'v tried to wipe factory data/cash partion/ delvic cash then flashed the file still nothing !!
please help my friend is going crazy !!!

That s due to a modem you update so go back to original modem. ..

Ohw ok.... When i flashed the file my sim card got the read the first time i restarted my phone. I don't get why it doesn't work for your friend. What you can try to do is to download (google) other basebands for n900 and try to see if those work (it doesn't necessarily have to be 4.4.2 cuz i flashed the same 4.3 file on my 4.4.2 phone and it worked). If that doesn't work you can try to flash a stock rom and then flash a baseband ( while still in recovery mode), try the one i uploaded. just be sure to have a backup of the current rom if the stock one doesn't seem to be solution.
Maybe start with these :

Did you backup efs? If you did restore it. If not then try flashing this in recovery.. Or try flashing stock again.

Actually it IS possible for the n900, the knox reset also let's users downgrade if they so choose to.. But he doesn't need to downgrade, he lost his efs/imei and that can be fixed if he made a backup or by using the other options that I listed.

Do not try to recover EFS...
It is not the problem, the problem is that you have unknown baseband (Modem damage)... Please check if it can mount /EFS folder (Check in recovery)
It it fails to mount /EFS, then you will probally need to find someone with a Asansam box to fix it...
Remember to backup you EFS folder
Best regards

IMEI null/null comes from modem failure. It is not because your EFS is wiped, if your EFS was wiped, then you would get a generic IMEI number 0044.....
But try to go to recovery, do you get "failed to mount /EFS"
But your IMEI null/null could also be a hw failure...
But I would try to flash a 4 part 4.4.2 firmware
Remember to backup your EFS, it is not corrupted...

IMEI null/null has nothing to do with a wiped EFS. It is modem problem, or HW failure. I would start flashing a 4 part firmware, eg this one

Hi friends. I am new to xda. I have same problem last 4 months. I have tried flash different stock roms but no use. When i check phone info it showing
Original CSC is INU. But showing other CSC is THL (wrong). Modem is blank. SW Version is unknown. My guess is modem and csc related issue. I have tried flash modem, but not affected. CSC also not affected. Why this happen?

IMEI. Restore backed up EFS folder .

If you don't know what you are doing my advice would be to
go to http://SamMobile.com and download the official kitkat
4.4.2 SM-900 firmware and flash it using Odin.
Be sure to do a full wipe including system, data, cache, dalvik
and last but not least a factory reset in twrp or cwm recovery
before you start the odin flash.
You will need to re-root your phone afterwards and install twrp
or cwm recovery. This is the surest way to resolve your network
and other issues.
This will give you a fresh clean start.

This will solve it.
Do you have twrp or cwm backup.
if not reflash VN rom 14.1 and you should get it back. secondly you can flash the modem attached.
1. wipe the device including internal memory in the twrp memory. put the phone in download mode. flash the modem via cwm rcovery
2. go back to recovery do just a factory reset.
3 now get any 4.4.2 stock rom for your region from sammobile and flash it using odin.
when the phone is rebooting and you see the Samsung logo pull the battery. put the battery back, go back to recovery do a factory reset. then let the boot complete.
it should be fine.
if it help don't forget to press thanks

if you flashed vn rom earlier you should just do it again. just make sure you do a factory reset , and dalvik wipe.

Install a factory test rom, backup efs, install whatever rom you want to install and restore efs if it doesn't work already.

i can help you with modem backup, but i can't send you EFS bsc of my IMEI
@twistergear
It will work, but, both phones will have the same IMEI #. That's the reason why no one will share their efs folder (files).
The best way for you guys is to send your phones to the service centers, so they can restore your own original imei numbers.
