I have a glide that for whatever reason only works on a stock AT&T ROM. either the gingerbread or the ICS but only stock ROMs. Any custom ROM I flash the phone looses its IMEI and will not function on the network. Once i either restore it from a backup or use the Samsung Kies app to do a firmware reset the IMEI is instantly back and the phone runs fine. I have a backup of the EFS file and once I've flashed a custom ROM if i restore the EFS still no IMEI I am at a loss up to this point any help would be appreciated.

I have the same problem and I get the generic imei, I also have an unknown baseband
I'm presently having issues with my phone displaying generic IMEI, but I can still use the phone on my network. I dont know how long I was using this for, but I can't seem to restore my IMEI from my EFS folder. I have a backup of my efs from November when I unlocked my phone using FastGSM. There are some posts in the SG2 forum and youtube videos but they are inconclusive with the testing I have done to restore my stock IMEI. I have a stock EFS backup that I'm attempting to hex edit but it isn't a rogers one so I'm really fingers crossed hoping for the best.
In the meantime, try and revert back to stock GB on your phones grabbing the firmware from Samfirmware ... sometimes you'll get your IMEI back, if you do backup the efs folder on your phone ASAP save it safe .. email it to yourself or do something static where the file will be saved in a unique place that it can't be changed.
I'll post a how-to if I get mine restored .... otherwise I'm really not sure what to do. It's super complicated to get it back without sending it in for service.
Phone: Samsung Galaxy Nexus GT-i9250TSGGen
I had a stock android version, that I never rooted or flashed. Suddenly the SIM stopped working, I figured out that there is no IMEI number and the baseband is unknown.
I flashed to a custom ROM, and tried to do few things using the Galaxy Nexus Toolkit:
1) custom ROM android 4.1
2) Flashed a custom radio
3) made a copy of the /efs folder, deleted the original and replaced it after restart.
The Samsung service center said the entire board has to be changed, with an estimated cost of $140 USD.
Can someone help me with my options? Is it definitely a hardware problem? is there anyway to know for sure?

If you have a nandroid back up, try and restore with it. This could solve ur problem.

Thanks, but I hadn't created a back up before. Is there a way to use a back up from a different phone? where would l find more information?

I had an old nandroid back up and I used the method in this post to fix my IMEI problem: forum.xda-developers.com/showpost.php?p=47048361&postcount=9
And when you said you took a back up of the /EFS folder, you meant pulled the .bin and .md5 files from the /factory or the /radio folders OR did you use something like kTool? Because, as people have pointed out in other threads there is no /EFS folder for the Galaxy Nexus. The IMEI information is stored in the Radio and Factory Folders. For more information on how IMEI works on the GNEx, refer to this post: http://forum.xda-developers.com/showpost.php?p=47045295&postcount=6
But you are saying the baseband is also unknown. A radio flash should have fixed it. Try restoring Stock ICS using Odin. i hear this fixes some problems like this. U can use thus guide forum.xda-developers.com/showthread.php?t=2065470
If Odin is a little complicated, try the Nexus Root Tool kit. U gotta experiment to find the right problem and them fix it. No other go. I doubt that replacing the board will solve it as it looks like a software issue, unless you fried your radios.

Thanks again. Yes, the /efs folder is not where it was supposed to be. I did find the correct location and moved it. I will try using your ideas. Just one more question:
Since I had not done anything that would wipe out my IMEI number (neither software hacking nor physical damage). I wonder why this problem suddenly occurred. Just to eliminate a possibility, how can I know for sure that I have not "fried the radios"?
Appreciate your help. If I know that it is a software problem, I can continue to play with the Nexus toolkit and try different solutions.

I'm not sure how to check if your radio is fried. Basically, it means something's wrong with your hardware, where you experience occasional or complete signal loss. But in your case, you lost your IMEI. So, back up your nv_data files, flash using NRT or ODIN and see what happens.
NRT will push the stock radio while doing the "Flash Stock + Unroot" Option. So, you'll get the stock baseband as well. This should fix it. If your IMEI still doesn't work, try restoring the nv_data.bin and md5 files you backed up as mentioned in the link I posted.
Let me know how it works out. :good:
Always make a backup of /EFS (Support in both PhilZ_CWM & TWRP )for safety, though the IMEI would be only wiped by CWM wipe /factory option......happened to me a few days back, luckily i got my /efs restored & flashing stock doesn't bring any IMEI back since it's actually phone specific plus comes with a proper MD5 !!
the above method should work and here more info on the EFS
Hello,
I have been unlocking for a while but have ran into issues lately with z3x and 4.3 on i747. Basically everyime i use 23x box something goes wrong last night it started with an extra number being inserted in the imei. Not knowing that ns pro will wreck your modem i tried it and now the imei is null and baseband is unknown. Any help would greatly be appreciated. There was alot i did not know about unlocking because i got into this with ns pro back when there was 0 problmes with anyhting below 4.3, but now 4.3 is killing me.
Here is what i have done
i have tried to rewrite imei mulitple times
i have tried qpst with a good know qcn fiel but it just error out. everytime
the problem
*#7284# shows up but wont allow me to switch between modem andpda
phone will not read in either z3x or ns pro
it would seem like tis not reading in qpst either as it wont allo me to restore any of the good know files
i just really want to be done with this and move on.
Another question i have is int he furute if i do a full nv backup with nv reader writer will this help at all. Like is said i am only having this problem ont he 747 and i have searched xda, ns pro, and z3x forums for an answer and i cant seem to find one. My next step is just to replace the baseband chip and be done, but that alot of work and i hate reballing any bga.
Thanks in Advance

NULL IMEI doesn't mean you've actually lost your IMEI
try take sim out, restart phone and then reinsert sim, and if that doesn't work, restart again with your sim inside
and also when you reinject imei(say whatever i said above doesn't work for you), make sure under developer option, usb debugging is on!

Looks like your modem is compromised. You can download the modem via the following link and try reflashing recovery.

No, it's a zip file which has to be flashed via (custom) recovery. If you do not have custom recovery, you can flash that to your phone via Odin. There are several options for custom recovery but most common options are CWM, TWRP and Philz Touch which is an enhancement of CWM.
First download the modem file to your computer. Copy it to your phone's internal SD card if you can or to an external (micro) SD card.
Once you have the zip ready, boot your phone into recovery mode via the 3-button combo (Volume Up, Home and Power).
When you are in recovery mode, select install and navigate to the modem zip. Start flashing. Wait for flashing to be complete and reboot to system. I'd have sent you some download links for custom recovery but I'm writing this in a fly. You could, however, do a search through this forum.

Larry thank you so much it actually worked in case someone lese has this problem im going to post waht i did
i downloaded the file
flashed the modem.bin file via twrp. I just put it on the phone i did not use the sd card
then i rewrote the imei with ns pro verision 6.7.1 (this phone was on 4.3)
i know have my imei back, and i know also i have the phone in 100 percent working condition with a full imei.
TAKE MY ADVICE AND BACK UP THE NV ITEMS before doing a s3 747 or 999 on z3 box just in case. I have spent close to 3 days trying to fix these phones.
Thank you Larry so very very much. If you have a link to paypal i will donate to you.
alos if you are going to install the file to your phone remeber to put it back into mtp+adb so you can move it your phone with out an sd card
ok so after completeting this you will only get edge network download the nv writer and nv items from the link below and then you will get 4g lte back

Glad to know your phone is working fine now. Maybe I should put up a donation link. Just kidding ... seriously though, if you are happy with the support you are getting from the forum and make a donation to XDA, you'd be helping to keep the forum going.
Thanks for the help to both you guys!!!

STILL NOOO HELP
Please me, i have lost my IMEI saying NULL / NULL and im getting not registered on error. I have not backed up ESF folder as well.
Struggling from last 5 days to fix it up. some how i got Modem_N7100XXDMG1 and flashed. After that i have got some fake IMEI.
Tried flashing STOCK ROM 4.4.2, but still no luck.
Read on some forum that MODEM of 4.1.2 or J.B 4.3 resolves this issue but when i try to downgrade from 4.4.2 to 4.3 via ODIN it straight away shows FAILS in RED
IM using Note N7100 K.K.4.4.2
PLEASE PLEASE PLEASE HELP ME.
If you have no backup and the stock ROM did not work, they you are pretty much out of luck. I had a backup but the IMEI didn't come back until I flashed a different modem. I used modem_XXDME4.
If you know what your IMEI number was, then there are ways to write that number directly into the phone. Need to send the phone to someone that has the hardware though. You can buy it yourself but it costs about the same as a motherboard replacement. Youtube "N7100 Android 4 3 imei repair z3x" to see what I'm talking about.
If you don't know the number, don't have a backup, then you'll have to change the motherboard.
You can find your IMEI number on the back of your phone though.. Pull out the battery, it's printed above your device's serial number.
I have my IMEI, i just wanted the solution through software can i change my IMEI or i have to go service center that would cost about Rs. 5000 minimum.
modem_XXDME4 is S3 modem, how can i flash it on note 2 N7100.
PLEASE HELP
@dineshdotcom2000 have you tried different modem? I had the same problem like yours and flashing my region's modem didn't solve the problem. I flashed European modem - modem_XXDME4 - and the dummy IMEI changed back to the original. Maybe you should give it a try.
Here is the link https://www.dropbox.com/s/5mrtz2c6s29ibxt/modem_XXDME4__.zip
I flashed the exact same file on my device and it worked. Good luck :good:

I have already used this modem. Right now i have some fake imei with "004999010640000/1 i want to replace this IMEI with my original imei on Note 2 N7100.
Any way to do it???
Please help
Find a service in india that has a z3x box. They can write the IMEI directly without swapping the motherboard.
just search, a few days ago there was the same problem solved probably in Q&A thread

Hi Guys !
Greetings to y'all!!!
I'm honored to be a part of this prestigious community at last and looking forward to give back, someday soon. My huge respect for all the contributing members, I have been using this forum to get help since 2016 and without even posting anything I've always managed to get helpful information to resolve every problem encountered till now ((rooting & flashing)).
:'D
So here goes my first thread:
A friend of mine recently tried flashing stock ROM on his SM-G988B/DS since his update firmware option wasn't working for some reason. Even though it was a success, in doing so he flashed wrong version of firmware and caused network failure, flight mode if tapped got stuck (greyed) (wrong modem was flashed). There was no backup and original firmware number wasn't mentioned so I tried flashing different versions of firmware (U1,U2,U3,U4 & U5) and finally got it working on flashing CP(modem file) of G988BXXU5BTJ3.
However, for some reason I still was unable to make a call, so I searched for it and found out that by dialing *#0011# my IMEI status is NG which is bad , even though my IMEI number is still intact as found on the back of the phone. I researched a bit further and found out that this has something to do with the EFS file and whilst going through comments in another forum I found someone else had the same issue and got resolved by deleting nv_data.bin file and its backup and IMEI folder in EFS file after rooting and reflashing stock ROM. I tried the same but found that nv_data.bin was missing in EFS folder, so I backed up EFS file and deleted just the IMEI folder in it and reflashed stock ROM, have tried flashing different CP versions aswell still no success .
I've seen some videos of Chimera IMEI rewriting and certificate patching and Z3X tool on youtube but in their case IMEI is missing and I don't want to go for those solutions for the instance. I'm wanting to learn from all this exercise and want to know whether what is what and how to resolve this manually (maybe by writing some hex code or script etc) if possible.
Summarized:
Phone: SM-G988B/DS
ROM: Stock (G988BXXU5BTJ3) (rooted)
Status: SIM Card Registration failure ( IMEI status NG)
IMEI : Intact (As on the back of the phone)
EFS file ( nv_data.bin and .bak missing)
Previous Status: SIM Card was working fine before flashing ROM
Your valuable suggestions in this regard shall be highly appreciated.

First, do a TWRP backup, all partitions including efs & modem.
Open the root explorer app, open the efs folder, delete the files named nv_data.bin
, nv_data.bin.md5 & the folder called imei. Then open twrp, wipe all partitions. Flash the latest firmware with Odin.

I'm wanting to learn from all this exercise and want to know whether what is what and how to resolve this manually (maybe by writing some hex code or script etc) if possible.
Summarized:
Phone: SM-G988B/DS
ROM: Stock (G988BXXU5BTJ3) (rooted)
Status: SIM Card Registration failure ( IMEI status NG)
IMEI : Intact (As on the back of the phone)
EFS file ( nv_data.bin and .bak missing)
Previous Status: SIM Card was working fine before flashing ROM
Your valuable suggestions in this regard shall be
