Hello developers,
I found the exact same problem posted on xda developers fourm but none of the posts were answered completely or solved.
I rooted my Sm n900 without any problems, installed CWM recovery, installed SuperSu and installed VN Rom for galaxy note 3 (referred this from some Chinese guy on web (since i cant post third party links) its galaxynote3root dot com.
At first i didnt check efs backup option and installed VN rom without any problems (no imei loss or baseband unknown) on my own phone.
But when rooted one of my friends SM n900 with exact same method as i did earlier (but i checked create efs backup this time), i got screwed.
I tried EFS professional, but when i try to put his phone in RMNET + DM + MODEM by pressing *#0808#, and run efs software, and click either qualcommn or efs professional button, it doesnt recognise the device and says not connected.
I tried various other options as well such as rerooting, reinstalling the rom, reinstalling OEM rom, and other roms as well. Every thing is fin except IMEI and baseband null/unknown.
I had a problem like that. On my note 2 .i flashed patition file in odin and it was fixed.

you should bring to the service center to record the IMEI number.
root your device and flash xxuene1 modem from recovery.
Modem is available on xda..search
I did the same and it worked for me
Not worked
Hello Fellas, am posting here as I haven't found help elsewhere. Kindly Respond to my woes. I have a rooted Galaxy Note 3 N900 running official Lollipop with IMEI Null/Null and No Baseband version. The IMEI just disappeared totally out of the blue as no custom ROM has been flashed on the device!! This has happened 2 months after updating from 4.3 Jelly bean. With no prior EFS Backup here's what I have tried:
1. EFS Professional (backup&restore complete but no luck)
2. EFS Restore express ( backup.bat>Odin restore)
3. GSII Repair tool
After hitting no luck with the above tools and without any "/EFS mount errors" in recovery either and WIFI working fine, I came to a conclusion that most probably the EFS folder partition on my Note 3 is still intact and most probably this could be a case of a bad modem which would explain the loss of Baseband Version and thus the Null IMEI. So I tried flashing back to KitKat with N900XXUENG1 firmware and separately flashed a few modems compatible with Samsung's new EFS System: N900XXUENG1_MODEM, N900_XXUENF2_MODEM_CWM and also gave a shot at recommended N900_XXUENE1_MODEM_CWM.ZIP which seems to restore baseband for many users with this issue but this failed as well. After much searching I found a 4file_N900XXUGBNL8 Lollipop Firmware with PIT from Dev-Host, flashed all files in Odin&even repartitioned the device but still no baseband!!! WIFI&everything else runs smooth except the damn baseband/Null IMEI! Almost Exhausted my options...
Now I trust we have some informed members and developers here, NEED YOUR VALUABLE IDEAS HERE mates! Someone, anyone.....Thanks!
Have got any guarantee of the device?If so,send it to service ıf your guarantee continiues.
If you bought the device from another country,This may occur ıf you didn't register it.(In my country this is how it works.Turkey)
Or someone cloned your imei,check your imei ıf it is valid.
This is not because you upgraded your device to android 5.
If ıt was the case,you would have already faced the problem after just the flash.
I would say flash another modem
But,You say you tried flashing other modems.So no luck with that.
I had seen s3 with the same problem.I had flashed a modded modem.
It worked.I dont know if there is one for your device.
Briefly this is an imei/modem problem.
I don't know ıf the suggestions above help you.
I hope so.
Good luck.
try flashing stock rom from sammobile via odin. you need to backup efs folder everytime you flash a new rom, that's my opinion. may be wrong.
I think I used to had this problem with my Note 2 as well. If you come from 4.3 you should flash stock ROM Jelly bean 4.3 from Sammobile or Samsung-updates website. Then flash lollipop 5.0 over 4.3 when you can see your IMIE. Maybe it will work.
So. If u in L bootloader. U must! Flash the L modem that sometimes didnt get flashed by the odin while flashing stock rom. So just extract the modem.img and things for modem. Then just flash it using dd command or make flashable zip. Then it works fine. I have it on s4 exynos. That if i in L bootloader then even i install kitkat rom with L bootloader. U must still flash the L modem. K. Hope it works
1. İf you couldnt recover with efs professional , probably you've been lost your original imei files like nv_data.bin etc. and there is no backup...
2. So try to remake this kind of files with-again- with efs professional. But there is not so much info about this "creation" process.
3. I had the same situation. . . . And i'm still sorry. . . ( . . . The other solution is JTAG, more easy, cheaper in total and psychologicaly healty !!!)
GOOD LUCK....

All EFS folder files are present including nv_data.bak&.bin Am a bit reserved to go the JTAG way just yet.

Thanks for that but as I already said I was lucky to find a 4file partitioned Lollipop ROM with separate modem. Flashed that through Odin and even repartitioned the device but that hit a rock as well!

It's an old device, no warrants. Am indeed looking at the possibility of someone else allocating the IMEI to their device, though i doubt. But if that was the case shouldn't the Baseband at least be present?
Did you try downgrading to 4.3 with official stock files?
If not,give it a shot.

I have explained it earlier, Actually it is kernel. Newer kernel makes some changes on EFS partition and that changes can not be read by old kernel but in this case once you flash newer modem it will be solved. If your issue doesn't solved by flashing latest stock ROM then only possibility is messed up EFS partition and for that you must have a backup which was created when your device was normal. If your EFS partition is corrupted and you don't have backup then i think only option you have is to go to service station they can repair it easily. Though your device is not under warranty but you have official bill then still they can do it with paid service. Now a days samsung have changed policy and restoring IMEI they needs to do it online with samsung server (this information I got from service center owner in my city who is my friend and he did same for one of my friend)

Thank you Dr.Ketan for that information. You have been a great help to many. I have followed your posts about this issue and I feel there is still hope.
UPDATE:
I WAS ABLE TO RESTORE THE BASEBAND AND NOW THE IMEI IS GENERIC, READS 004999010640000. [/B] I was able to restore nv_data backup from /Efs folder and deleting bad nv_data. Here's what I did:
Using root Explorer in /EFS:
Deleted corrupt files;
nv_data.bin ( 18 April 2015)
nv_data.bin.md5 (18 April 2015)
Renamed backup files (dated 31 Jan 2015) to apply;
.nv_data.bak > nv_data.bin
.nv_data.bak.md5 > nv_data.bin.md5
Using ADB shell:
Code:
adb shell
su
umount /efs
mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3 /efs
Reboot
However, the baseband and generic IMEI come&go across reboots and seems not to stick permanently. Any possible steps from here???
NOTE: Previously I have been able to restore Unknown Baseband and Null IMEI in Galaxy S2 i9100 using the above adb method (Code Only) http://www.selftechgenius.com/?p=284

I always have that problem when I downgrade to jellybean but solving it is easy. Just flash THIS modem file under the AP option Odin. Tell me if it works.

If flashing modem via Odin you MUST turn off the phone then start it in DL mode. Simply doing a 'reboot' into DL mode will not let the modem be flashed.
Hi
it's my dad's phone and has been dead for a while now...
I have an I9500 and after upgrading to a new version (stock on the air upgrade done by my dad) it shows IMEI null and no sim card detected.
I tried these steps:
1) root, philz recovery
2) install latest modem
3) restore EFS (dont have a working backup so didnt help)
4) back to stock rom as recommended here by some folks.
5) edited the efs file (a bad efs with null imei) using HexEditor and wrote my IMEI on 0x800000 address.
6) flashed cm
nothing works!
plz help!
Your phone IMEI is listed under the battery in the phone. But I'm not sure how you re-enter it.
I lost my IMEI when I was on a custom rom 5.1.0, got it back by flashing 4.4.4 stock via ODIN
My phone is an I9505
Take the phone to Samsung and have them fix it, as you've done everything you could to resolve the problem yourself. After all, if their OTA update did screw the phone up, they should be responsible for fixing it.

Download and flash it via odin
it rooted successfully but when I restarted my phone ..it was custom binary blocked again
I know there might be another similar topic but I couldn't find any help so far.
Basically two days ago I flashed custom ROM on my phone, I didn't make any backup. At first it worked perfectly. I decided to flash ROM again and formated my phone and found out that EFS partition was lost. I didn't get any mobile data and my IMEI number was lost (0000000). I've read that IMEI is actually stored on some chip so is there any way to restore it back? My phone is Samsung Galaxy A5 2017. Any help will be appreciated.
Trying to flash latest stock rom from sammobile but after flashing it with odin it starts bootlooping and saying "no command" again and again. When holding power + home + volume up I can NOT access recovery. Any solutions, please?
Anyone? Is there any solutions for my problem??
Is it possible to downlaod EFS file for my phone and somehow change IMEI in the file?
just flash stock rom, i did on my galaxy ace i flashed custom rom and imei gone, after stock flashed via odin imei back.
Thanks for your answer! I tried indeed flashing latest stock rom from sammobile with latest odin. But when I bootet phone up it said "no command" with dead android logo and kept bootlooping. I can try different version of rom, maybe it helps.
Still my problem is unsolved. Any clues what to do would be great.
You probably flashed a wrong firmware which is not for your variant.
Can you remove your battery? If so remove it and put it back and enter download mode by pressing volume down,power and home button. Afterwards, find the firmware which is for the specific variant of the phone. Only get the "HOME_CSC" version or else you will lose all you data. In odin, if it says added, flash the stock firmware and see if it boots to the system. If you could give me your variant, I could help and give you an even more detailed guide.
