Hello!
It's Briefin here, [okay first a quick background of mine: I'm very familiar with Custom Roms/Recovery/Rooting/Kernel etc. And have been doing it since a long time. Never got any significant issue to write on XDA. So it's my first thread. ] Okay now the issue is I recently flashed the EFS Partition of an another device (A TWRP backup file). The device from where I got the backup file was of the same model as mine of course. So it should be okay I thought. But after that, my phone's network signal stopped working. Tried everything available on the web but nothing worked. My whole IMEI is just messed up. It's showing 0(Zero). So my question is, is there any way that I can rewrite my IMEI?
Device name: Asus Max Pro M2 (X01BD)
Thanks!
Need a proper EFS
Same problem occurred with me. Mobile networks not working. I am a newbie in this section (custom ROMs). So I need a proper EFS backup(if this works).Please help someone.
maybe you can try this one bro
Messed With IMEI while Enjoying flashing?
IMEI number is a personal identifier and if gets corrupted you can loose working of SIM in those phone. Why would it happen? 1. Probably you went High and cause your modem to get corrupted? 2. Or the Old way deleted/removed/ate away NV_RAM file...

I tried to install the new version of CyanogenMod Snapshop but unfortunately afte the reboot of my LG G2 D802 the mobile phone bricked.
I read a lot around the Internet and finaly i succeeded to unbrick it. Th problem now is that i do not have IMEI (is null now). I read that there is one program that you can fix your disappeared IMEI but cannot work in my personal laptop. Do you know anything how to repair and fix my IMEI with my previous official IMEI (i have it in the box that i bought but i didnt have any backup of it).
Thank you
I am having the same problem. I was loading a milestone version of a rom and when it loaded after wiping there was no service whatsoever and everything is null. I understand it wiped the efs and I dont have a backup. I also understand that we can change the info back with the numbers off of the original box using dfa cdma tools. I have the program but my question is the 000000 code does not work when i try to unlock the phone. Anyone with any experience with this program that can help me to re write my meid???

Which program do you have?
Dfs CDMA tools
I don't have any personal experience with this, but I have done a ton of reading on this problem and it's become my biggest fear. From what I have gathered you have very very little chance of fixing this yourself. It most cases it goes back to the manufacturer. Can you tell us exactly how this happen?
I have no idea, i have been rooted for months and swapped roms like crazy. I wiped and installed a new rom and then it was getting no service so i tried to update profile and said it couldnt. Then check in the settings for the baseband and meid and unknown was shown across the board. Trying to figure it all out now!
I have had the same thing happen what cm did u install I had a d802 version on my ls980 restored it but now it will only accept a d802 modem and the signal is weak and drops out but it did show my ESN and imei and baseband again instead of unknown if I would have flashed it with a ls980 modem

Have you tried restoring a backup?
Sent from my dr87 v7 powered, Mahdified LG G2 (D801)
My problem started when I tried to update my LG G2 D8002 to the latest Cyanogenmod Kitkat Snapshop and i stuck in clockworkmod recovery loop after returning in CWM to take backup. I tried to connect it to my Laptop but i cannot have any access in my files via my laptop. The bad thing that i did is that i formated everything in my mobile (as you can see and my IMEI too) to make a clear installation of a new rom after the brick. When i entered my new ROM i realized that i have everything apart from my IMEI. So that i do not have any network-signal in my mobile but a connection to Wifi
The program Dfs CDMA tools and Octopus Box does not work in my desktop. (Any idea?)
Do you have any idea how to repair it? I read that there is a folder (nfs i suppose that encode inside the IMEI). So, if someone find this folder can upload it somewhere? Probably will find a solution to solve it.
i was solved problem with no imei :
make full buckup from TWRC in another LS980
restored that buckup in bricked phone (make first buckup on it, to know name of folder, and take to that folder buckup from work phone)
sorry for me English

Are you sure that this works in all devices of LG G2?
Alright, so I paid cellunlocker to unlock a new to me Note 3. Not blacklisted, everythings good on that end.
my IMEI shows as the correct number with two extra digits - not sure if thats my issue.
However I cannot connect to any mobile network. Well thats not true, I can see I'm connected to their tower but cannot get any phone calls, texts I just get the message on the screen.
I didn't back up my EFS partition, having 6 android phones so far all, rommed, and everything I never had to do that.
I understand its likely that this partition is messed up.
.. So how can I restore it?
I'm rooted, I'll install a recovery I don't mind any of that. however I do not have a backup of my EFS partition. Is there any way to extract this from a stock file?
Can I just use Kies or something to flash the entire software and restore this partition?
Seeking some guidance from the Note Experts.
Thanks,

- The extra 2 digits after the IMEI is the IMEISV. It is not the issue.
- The EFS partition is store inside your device, not in the stock firmware. Of course you can not extract it from the stock files.
- You can try to flash the entire stock firmware (using Kies or Odin). Sometime that may help to fix the problem.
Appears to be a case of delayed blacklist or something.
Didn't show up in any searches and not to my carrier, yet later now it does appear it is.
Now to return it to the carrier so they can get it back to the owner, and to track down the ass I bought it from.
Hi everyone,
My S4 has lost its IMEI, and here is my situation.
I was using Prism v14 (http://forum.xda-developers.com/showthread.php?t=2537515), and it was totally fine. Last night, I tried to flash a new S6 port rom, this http://forum.xda-developers.com/galaxy-s4/i9500-develop/rom-aurora-s6-port-t3063408, and my fone lost its signal. The signal icon is still full, but it was only available at emergency calls. When i check, IMEI and Serial number were still there. I tried flashing the Prism v14 again, didnt fix it.
Then I took my fone to the care center and left it there for a few hours. When i come back, they told me that, they flashed it back to stock, and when i ceck, the IMEI was gone. They explained that, when I flashed the S6 port rom, the real IMEI was gone, it was only the fake IMEI from the rom that I saw (didnt know if this was true).
So now im asking for any possible help/solution. I was bad to forget backing up my EFS. So i wonder if I can use someone else's EFS to restore? If yes, it would be great if any one can share with me the EFS backup.
Thank you for reading and please excuse my bad English.
The EFS folder doesn't store the IMEI, despite having an IMEI folder, thus it won't help you. nv_data.bin also will not be found there, if my S4 is any indicator, but will be found in the hidden partitions.
You'll need to try flashing the baseband for your device again, and to do that you're going to have to download a copy of the ROM, which should be found on the forums here. Sometimes the baseband needs to be flashed twice for everything to properly work. I can only speculate why that is, but I believe it to be due to having two hidden partitions for the baseband. When the baseband is copied into the first partition it isn't copied into the second, resulting in a mismatch. Flashing the baseband a second time writes the baseband to the second partition, and everything functions correctly.
If flashing the modem again does not work, getting your IMEI back will require using methods that cannot be discussed here on XDA.

Do you a have a efs.img backup ? Or any kind of IMEI/EFS/RADIO backup ?
I had the same problem I flashed the stock ROM and somehow I lost my IMEI info, I tried everything and I was even thinking about buying a z3x box but then I decided to do a very risky move , I completely deleted all the EFS related files/info and reflashed again but now I was not able to boot because I always sent me to recovery mode saying that :
"E:Failed To Mount /EFS (invalid argument )"
Then all I did was installing TWRP and rooted my SM-G935F and then I placed my efs.img backup on my internal SD CARD and went on recovery launched the terminal and wrote this :
dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS
Then I wrote reboot and it finally my phone was booting and I recovered my IMEI and was able to use my phone normally.
This only works if you have a backup of your EFS, and even if you do is risky , but I did it because I lost all hope and was accepting the fact that my phone would just become a useless wifi only device .
So there is not a fix yet for this problem ?
I have a problem on my s7edge instead. If i have valid imei i'am almost always in emergency calls, and when the signal comes back does not go into mobile data connection. With the wi fi no problem.Can someone help me i'am going crazy.!
IMEI, Network Signal and Baseband is misssing

IMEI, Network Signal and Baseband is misssing
Hi
I am ready to donate if any expert can help me to restore IMEI.
I am using SM-N9500 samsung note 8 model - hongkong version, i frequently change the roms.. when last time i tried to install a custom rom i lost IMEI. i am getting error like IMEI-unknown, baseband- unknown, no network and sim cards not working..
i tried installing stock rom, custom roms, it was installing successfully but only baseband, signal and IMEI are not working. i didnt even back up my EFS folder. So, kindly help me to get back my IMEI.
I have installed stock rom, still no IMEI. now i rooted my mobile and taken EFS backup. is it enough? if yes, pls suggest me the next steps. I also tried installing combination firmware, though is not working, installation was successful and also i am able to see the factory binary logo, after which it will switch off automatically and boot loops. everytime it will open factory binary and immediately it will switch off automatically..
Build number - R16NW.N9500ZHS4CRJ1
Hello, everyone! This is my first post on XDA so sorry if it ain't in the right place.
So... What I did is manually updated my S8 to Android 9 through Odin but it isn't receiving signal and it shows that I'm not registered on network. I already tried everything I could but I can't solve this issue. Can someone help me?
Edit: my phone was working perfectly before I ruined it all.
IMEI ok, signal ok, it's not a hardware problem. I've tried configuring APNs and the ROM is the correct for my phone, country and carrier. I just don't know what is wrong. Thanks for all the replies
Try these:
Reconfigure APN's in the cellular data settings.
Check if your phone has IMEI, if you flash-all you may also lose the EFS partition. If so you have to restore your EFS partition backup.
If you flashed the wrong carrier's android, you'll have to flash the correct one. For example your phone is T-Mobile, but you flashed AT&T version.
Goodluck.

Hello! Thanks for commenting.
I tried configuring APNs but it still not working.
I'm sure I flashed the correct ROM.
I think I lost the EFS partition as you say, since I didn't backed up anything (I'm feeling silly). How do I restore my EFS partition? Thanks again!

Check your device IMEI first if it says null or unknown or something similar then you indeed have corrupted EFS.
To check your device IMEI, open dialer then dial *#06#
As for how to fix this, as far as I know without a backup you can't. EFS partition is automatically backed up in any nandroid backup made by TWRP.
You can try XPOSED IMEI changer or if magisk has a similar module.

I honestly have no idea man, sorry not being of much help.
All I can help with is provide you with this tool.
On a side note the image you put there is completely useless and it only exposes your IMEI. The barcode also contains info about your IMEI.
Goodluck.

I saw your thread and my guess is that your device is network locked by IMEI, if you contact your network provider they can confirm it for you otherwise try a different sim card and see if it works.

perhaps you need to reflash the modem.img on your device, you can get it from here
Did you find a fix for this issue? I've same issue with my S8+. Phone keeps saying there is a Network or SIM Card error on any Lineage ROM (with Android 12 or 13).
