Use the search feature there are many guides and tutorials on this subject already.
GT N7105 with XDA Premium......that is all......
I did that, i found this one. http://forum.xda-developers.com/showthread.php?t=1308546&page=141
But i dont know if it can write my imei back.
Then i found this rj-45 cable but it need a especific box to restore imei.
I did the search, if i wasnt lost i wouldnt ask.
Thanks for the help anyway
I recently went through this similar pain (last weekend). I had defaulted to the default IMEI, then deliberately removed the EFS folder to see if it would regenerate and the value became null.
In short, the way around this problem, as I also had no EFS Backup was to use the Emergency Firmware installation feature in Kies, which utilises the Serial number of your phone to determine the stock ROM required. I essentially restored it to out of the box state, with IMEI intact. I uninstalled Kies (as it has issues with the Toolkit) and using the Toolkit and Odin re-rooted, and backed up the EFS folder. Took multiple copies of this on e-mail, elsewhere on PC and SD Card! Restored ROM with Mods etc that I required, restored EFS Folder using an app called "nitrality" and wiped cache before rebooting.
IMEI and ROM back to what I wanted. Phew!
There are multiple methods documented on these forums, and the more detailed steps to the approach above is on here somewhere. Utilise the search to help yourself some more but I hope this is useful!

My experience
Well, I had this same problem because of the wrong ROM i installed, I am from the netherlands and my modem/kernel is: XDME4, however, when I installed a rom with another kernel/modem/Baseband name I lost my IMEI and network signals, All I had to do is flash a different kernel, and I got my IMEI back
Hope it helpt!
UPDATE: In my case, I lost nothing, but its on your own risk! If you willing to lose everything because you want to fix the problem, you can also try to flash back to official rom, and then flash a custom rom (not the same as before), or make a backup first, using Titanium or ROM Manager kinda apps,
Regards!
Last June I experienced the same problem upgrading the firmware of a brand new phone, completely stock and not rooted.
Before the upgrade, made with KIES from PC, I had this:
AP: N7100XXDMB2
CP: N7100XXDLK7
CSC: N7100ITVDMA1
After the upgrade I had NULL IMEI and this:
AP: N7100XXDME6
CP: Unknown
CSC: N7100ITVDMF1.
Since I had no EFS backup, I tried to use the Emergency Firmware Installation feature in Kies, but it didn't help.
I couldn't yet figure out what this problem depends on. Can anyone explain it to me?
I solved making me replace the phone at the shop. The new one has DMC3, but I'm scared at the thought of updating it again.
efs restoring query??
hello everyone, i ve a efs backup, backedup wen im running on 4.3 (xxuemj5). is it possible to go back to 4.1.2 (N7100XXDMB2) and restore tat backup (backed up on 4.3)? i had a prob (" not registered on a network") last time wen i went back to 4.1.2.

No, you should restore an EFS backup made on N7100XXDMB2.
Try this, worked for me
check my other post. I fixed it http://forum.xda-developers.com/showpost.php?p=57991998&postcount=85
Friends I tell them what happened to me! I have a galaxy note N7100 2 and started to install a rom amending the efs folder (something you did not know) as a result I change the imei to 0049xxxxx and good after spending almost a week reading forums got a solusion, not if it was luck or me but I managed to put again flashing the rom imei assassin's. When installing did not give a efs backup and install it all, this rom gives you the option to put the kernel that you want and the modem, I am from Venezuela and trying to install the kernel branded the same rom but I chose the 3rd bottom-up modem. All fine, put me back my imei now had the problem of the signal, it sends me ariza and accommodation. Now a question, if I have signal when reviewing my efs folder is corrupt? I want to go back to have that repaired folder because I can not flash another rom and would stay stuck in this rom, having it bad I would present the same principle failures. If anyone knows how to fix that folder I would appreciate very gusto.Y if anyone has my problem and has the same model you have, this mas say I'll help you with pleasure.
Hello guys. A while ago, I received a update/upgrade from Color OS to the latest version(don't ask me which one,cause I don't remeber :/ ).
So, I did the update/upgrade, and once I rebooted the phone,my NV partition was gone,as well as my IMEI..
But before all this, I was having unified storage made available by COldbird,and everything went fine,and I also managed to get the backup that was made when I unified the partitions.. And that backup is stored on my laptop.. I was wondering if there's any chance that I can use that backup to restore my NV partition and consequently recover my IMEI,although it's written on the back of the phone,and also in the invoice,sent by the crappy sellers( that aren't able of helping me in this situation,because the warranty and their store only fixes hardware issues: the seller is Mobicity UK btw )
I've already been in touch with Oppo, but so far haven't heard from them..
Right now,the phone is running on Nameless rom,but I can always get it back to the factory state,although it won't create the NV partition...
Any suggestion on how to solve this situation??
Thank's a lot for all the attention
Question for those of you who may know more than I do.
I have…well had, a Sprint Samsung Galaxy S3 that got a shower over the weekend. The USB port is definitely fried, and who knows what other damage may have occurred, but the phone still turns on and works fine. I decided to buy a used S3 to replace mine rather than try to fix the port not knowing if that was the only problem.
Now my question, my phone was rooted at the L710VPBMD4 OTA level, I have 4.2.2 CM v10.1.2 installed on the phone, and would like to keep it that way till I make sure everything is working the way I had it.
If the new (used) phone I receive has received either the L710VPUCMK3 or L710VPUCND8 OTAs will I have any problems loading my NAND backup and TB backups to recover my phone to the point it was wet?
(luckily the phone still had enough battery power to get these done)
Added: I also used CWM Recovery v6.0.3.0 for My NAND backups, do I have to continue to use this version to recover properly from, or will it work with Philz Recovery?
If there is a problem just straight loading my backups to the phone, is there anything I can do to make it work?
I know there is a root method difference for the L710VPUCMK3 or L710VPUCND8 OTAs, I’m just concerned about being able to recover my backups at the level they are at. Right now I don’t want to have to upgrade CM until I make sure everything is right, even then I will probably only upgrade to 10.2.1, as CM11 doesn’t seem quite ready…at least from what I’ve experienced on other phones/tablets.
Thanks in advance….

Well.....as long as the bootloader and modem weren't backed up you should be able to restore the CM11 as long as you use the same recovery......that being said you won't be able to restore the stock rom cause i believe the bootloader and modem get backed up with that one. Also it could come with the NJ3 update in which case you won't be able to root at all. I also wan't to add that i have no faith in TB for restoring app data cause that will cause problems with your phone.

I will be restoring a CM10.1.2 mod, not CM11, if that makes a difference.
So I will need to use CWM 6.0.3.0, and can not use Philz Recovery. .. Just verifying.
I’m not worried about using my old stock rom backup, I can get a new one with the new phone, my old one never had anything on it, as I loaded CM the day I got the phone new.
How can I tell if the Boot loader/Modem are a part of the NAD backup? The files I have in the NAND are:
boot.img 10,240 KB <--- would this be the boot loader?
cache.ext4.tar 0 KB
cache.ext4.tar.a 54, 238 KB
data.ext4.tar 0 KB
data.ext4.tar.a 976,563 KB
data.ext4.tar.b 976,569 KB
data.ext4.tar.c 728,600 KB
nandroid.md5 1 KB
recovery.img 10,240 KB
system.ext4.tar 0 KB
system.ext4.tar.a 350,522 KB
Is NJ3 a Sprint released OTA? It was not in their list, ND8 was listed as current. The phone I’m getting should be a sprint phone, but I won’t know what level the phone is at till it gets here Wednesday.
As for TB restore, I shouldn't have to since my NAND is current, but so far I’ve been lucky with TB.
@bilgerryan do you have any advise for this person i have reached the limit of the help i can give with the experience that i have on this version of the phone....
Thanks for your help, I'm trying to get as much information as I can on this before I get my "new" phone and brick it with what I am trying to do.
Once I have the phone it may not be an issue if it hasn't received OTAs, the best scenario is that is at the MD4 level, but I doubt I will be that lucky. I expect it has been updated to MK3 or ND8, which is why I am asking what I'm asking.
OK, my guess is that boot.img is not the boot loader, as I see that file in CM ROM zip files, and CM ROMs do not contain a boot loader, can anyone confirm that this is correct?

no problem and if anyone can help you more then me it's Ryan since he still has the Sph-L710 and he's a Developer.....while i have the newer Sph-L710T and im on Boost Mobile
Few follow-up questions:
1) Will CWM 6.0.3.0 work fine with the phone has been updated to MK3 or ND8?
2) If not, can I restore a backup made on CWM 6.0.3.0 with CWM 6.0.4.5? (seems to be the latest version)
3) If the “new” phone is on MK3 or ND8 can you still use a previous android version, like 4.2.2? (This is basically what I will be doing, but using a NAND backup to restore the phone)
4) Will a NAND backup contain the boot loader or modem? How can I tell if mine does?
This would prevent me from being able to recover with my NADN backup, from what 6th_Hokage said, and from what other information I’ve read on this. It would brick.
Still hoping I can using my NAND backup from MD4 phone to recover to a phone that may be at a higher level. So far from all the reading I am doing on this I should be able to, as long as I don’t try to flash the firmware back to MD4. Which isn’t an issue if my NAND will work, if it won’t then I’ll just be forced to rebuild from scratch, which I am REALLY hoping to avoid.
Ok, after reading as much as I could last night…my head hurts…
But it looks like I can do what I hope to do, if the planets and stars align.
Best case scenario, the “new” phone I get is at MD4 and is the SPH-710 variant. (doubt I can get that lucky)
If the phone is the SPH-710T – It goes back and I’m out of luck, as it’s a crap shoot buying a used phone when they don’t make a distinction between the 710 and 710T (Thanks 6th_Hokage, when you mentioned the 710T and on Boost Mobile, I figured it was a variant for them and VM, not for sprint, I’ve found out it is a sprint branded phone too)
If the phone is a 710 variant and even if it has been upgraded to MK3 or ND8 I should still be able to use my NAND backup to recover my old ROM (4.2.2 CM v10.1.2).
I should be able to use either CWM 6.0.3.0 or CWM 6.0.4.5 on the new phone to restore my NAND that was made with CWM 6.0.3.0… even if the phone is at MK3 or ND8.
My NAND should not contain the boot loader or modem, but I’m not sure how to tell. If it does, I’ll need to figure out how to make a NAND that exclude them. How can I tell if my NAND contains these? (because if it does and I restore, it will brick, if on MK3 or ND8)
If anyone can provide some insight on this that would be great.
Thanks,
Next on the list of my research findings.
I have found conflicting information, in one post I found that I would get an asset error if I try to install CM 10.1.2 (or I think any 10.x version) when on either MK3 or ND8. Then in another port I read that there should not be a problem installing any version of CM when on MK3 or ND8.
Can anyone confirm either post? Can CM10x work on MK3/ND8? Or will an assert error get thrown?
If an assert error is thrown only during install, I wonder if I bypass this by using a NAND restore like I plan, since the “install” of CM has already occurred, and I am just restoring a backup.
You may ask yourself why I am going through all this to recover an older version of CM. Well my phone was completely stable where it was, it did everything I needed to without error. While I’ve considered upgrading, that always seems to introduce issues, and I needed a smooth working phone over some of the stated benefits of CM11.

Yes, I was able to restore the NAND backup with my S3.
I had a NAND backup of
CyanogenMod 10.2.1
that was on MD4 before
on my Sprint S3 SPH-L710.

Great to hear it will work, now just have to hope they didn't send me a 710T variant...Will know tomorrow.
Hopefully it will work the same with CWM, as that is what my backup was made by, I've read that CWM and TWRP backups are not compatible.

Correct, not to mention TWRP doesn't mount or storage correctly anyway. I suggest using Philz, it's a zero issue recovery.
Will Philz correctly restore a CWM backup?
If not I'll have to stick with CWM until I get everything back working.

Well PhilZ is literally a touchscreen CWM and every time I made a backup with it the folder where the backup was is called "Clockworkmod" or "CWM" I can't remember the exact wording cause I've been using a beta TWRP made for the L710T
OK partial success, significant failure.
New phone received, it was an SPH-710 model, but was at ND8. But from what people have commented and what I read this wasn’t going to be a problem.
SO I rooted the device, all went well.
Restored my NAND backup, all went well.
Restored back to stock for activation, trouble started. IMEI information is gone !!
Restored back to CM10.1.2, IMEI information is there, but it contains the previous owner’s phone number.
I am able to activate the phone, everything seems to go fine.
I reboot and get data, I can receive data. I rejoiced.
I tried a text, fail.
I tried a call, fail…the rejoicing ended.
Checking phone status the person’s old phone number is still associated with the phone.
Normally this would be taken care of in stock by doing a profile reset. So Im not at a loss..
I need to see if I can recover the IMEI information in CM and transfer to Stock to do a reset on the phone to get it to activate right.
Any Ideas? I'm going to start a new thread just on this question, as this one was more about recovering my old phone to the new one.

Not exactly, while I was able to restore the NAND backup, it was not usable, I could not activate the phone because in stock all the IMEI information was blank. I was able to recover from that. So now I am trying just to load a fresh CM10.2.1 onto the phone, but it's giving me issues. Starting HERE at post #1848.
Hi, Yes you're probably right I shouldn't have messed around without knowing exactly what I'm doing, but any help would be greatly appreciated, I have tried to search for answers on here, but the forum is running so slowly for me at the moment that searches just time out for me.
Anyway, heres what I did - I rooted via ODIN, (CF-Root) and installed CM12.1 - First though, having read about the EFS risks I thought I was covering my ass by downloading EFS Backup from the Play Store - I then backed up my EFS Partition, there were three options, and I assumed the safest option was to leave as default (tar.gz)
So when I saw I'd lost my IMEI after flashing CM, I reinstalled the app, tried to restore - which directed me to an app "Partition back up", which turned its nose up at my tar.gz files! (thanks for that EFS Back up!)
Can anyone tell me what I need to do with the tar.gz files? and do I need all of them?
Thanks in advance.
Partition backup?
Just use the restore options in EFS PRO. What's inside the archive, images or files?
I've just got a file of tar.gz's Radio, CDMA Radio, EFS, and three named M9kefs1 ,2, & 3
I copied them onto my Mac and managed to open them, which gave me .img files too, Which I've tried restoring on the tablet (using Partitions backup app) It reported success but didn't work.
I'll try this EFS Pro, I had seen it mentioned wasn't sure if thats the way to go, thanks!
I've got to ask, why through all of this you didn't use the one tool that would have solved your problem in minutes. TWRP?

To back up EFS you mean? Quite simply I didn't think I needed to, I thought I'd done it with the EFS Back up app

There's nothing better than making a full backup in recovery.
It's your one and all get out clause if your device ever doesn't boot or something goes wrong.
Backup apps rely on a Bootable system.
In fact I would suggest you do it before going any further.
I suppose I wasn't too bothered, as coming from an "empty" tablet with no data loss to worry about, I had in my mind that if all went tits up I could simply flash the stock firmware with Odin. (Which I've now done anyway as EFS Pro wouldn't play ball)
Thanks for you help! Lesson learned on Backups.

Stock Firmware does not flash the EFS partition.
If it gets wiped or corrupted it's gone and not recoverable.
You have been lucky.
Well flashing the stock firmware back cured the problem, Must be a CM12.1 issue. That would explain why restoring the EFS .imgs didn't work either then.
Hi, I have a similiar issue with my SM-T705. I have the stock rom installed. My IMEI number seems to be broken. It's a generic imei 00499 number. However, I still have my box laying around which it came in. Is there any way to restore it from that?
