Hello everyone,
I'll admit, I flashed a CWM touch recovery to my phone believing it was meant for it, turns out after CWM flashed it that it read something about Nexus 7 touch recovery successfully installed. I was like "NO!" Since then I had to restore my /efs directory from scratch. Only I still have one problem. I have a generic IMEI and AT&T suspended my service. I called them to restore it, giving them my real IMEI from behind the battery. Service came back on immediately after they confirmed it on their end however my phone still shows an incorrect-generic IMEI. How do I get my real IMEI programmed back onto my phone again? All help is appreciated. I'm currently running a CWM/SU injected stock ICS ROM.

if you are stock ics i'd just odin back to stock ukk6 or whatever it was (gingerbread). Just for a fresh start and see if that helps...other than that i have no idea.
Update
I've done enough searching to understand somewhat that this relies on the nv_data.bin file that is located inside of the /efs directory. I've gone in to look at the file through hex editor and have managed to change the model number back to my correct one (SGH-I777, it was showing SGH-I897Z or something before). My best guess is that the data in this file is either showing the incorrect IMEI but I just can't figure out which hex line it is so that I can go in and change it. If anyone beats me to the punch please let me know! Hope this helps someone else out too!
Going back to stock may help. I guess all you can do is attempt to restore your /efs again. I was in a similar situation (generic imei due to an unlock tool) and ended up having to get warranty repair. I had several /efs backups and attempted to restore it using numerous methods: all to no avail.
It appears that your options are as follows.
1. Keep attempting to restore/repair /efs (tons of threads around on it) using multiple tools. The key lies in the nvdata.bin file.
2. Samsung Warranty Repair
3. Mobile Tech Videos repair
4. AT&T insurance replacement may be an option?
Just a few questions then...
1. Will flashing to stock 2.3.4 2.3.6 overwrite the /efs directory to where it goes back to stock too?
2. Is there any harm in leaving the generic IMEI in place?
I think I'll close this thread after this.
Thanks!

1. It might work; didn't for me. I've seen it suggested numerous times around /efs threads.
2. Not really. Carrier-wise? Yes. Once AT&T blocks it, there's no way around keeping it in place; you won't be able to use it. I've also seen people report that PC market installs were wonky or occurred randomly from other origins (as a result of having the same imei as other devices).
have u tried this guide yet? as long as u have the original shipped EFS folder this should work. http://forum.xda-developers.com/showthread.php?t=1264021
also try this EFS PRO tool, kinda old http://forum.xda-developers.com/showthread.php?t=1308546
good luck!
Dear All,
My Galaxy S3 cannot connect to network after rom update. I have searched a lot but i could not figure out the problem since i have no problem with my imei. I can see correct imei, but no serial number no hardware revision and no signal when sim is inserted. without sim it can detect signals.
To figure out problem i need EFS.tar of some working I9300. If some one can provide me his efs backup in tar, i will be a big help for me.
ha ha ha ha ha! You really think someone is going to give you their efs?!

Sorry to be the one to tell you this, but without a proper backup, you almost certainly won't be able to recover the efs folder. That's why backing up the efs folder is so critical before you begin any flashing procedure. It contains information unique to your device, without which, you have basically a very expensive media player.

Does this means that even if have another efs folder it will be no use to me?
I have my EFS folder intact and it has all files in it. but there is some problem with any file, that does not allow to register to network.
That's quite unfortunate, backing up my EFS folder was the 1st thing I did after getting my phone to avoid this kind of issues (prior rooting, of course).
By the way, was it an official OTA update or was it manually injected?
Any piece of information you can bring about the issue may help people here to figure out a way to help you.
How sure are you it is the EFS that's the problem? If you can see the folder and it has files in it, why are you looking at EFS being the problem? I'd have thought with a corrupted EFS you wouldn't have a file structure to be looking at, but I may be confused as to what an EFS is/does)
Have you tried using CWM to Factory Reset, wipe data and Dalvik and then run your Rom again?
Have you tried downloading and flashing a stock ROM for your phone?

Infact there was an OTA update but it failed to install from stock recovery mode. After reboot there was a message to use kies or contact service.
So i used. But kies showed that it cannot updte this phone ( because CSC was XXX ) so i used firmware inatialization method to download firmware by entering model and serial number in kies.
After update i was stuck in this situation,
Have you flashed a stock Rom with Odin to try and rectify?

Yes i am also confused about this.
Befor touching EFS folder i did factory reset, wiped data, delvik , re installed different official and custom roms. But it did not solve my issue.
I focused my attention to efs because all my symptoms are similar to people who have lost their imei. But my imei is O.K
You have any other suggestions.

I flashed LE8 and LH1 via odin , but it did not help
If your IMEI is intact its not generally an EFS issue.
Asking for someones EFS backup is generally a no no, and it wouldn't work anyway.
My understanding, from reading what Odia posted (who is generally considered the expert on this sort of thing) is that the EFS is in part encrypted with the devices ID, so if you use someone else's EFS on your device, it will fall back to the generic IMEI which would be worse.
Try flashing a full odin firmware and go from there.

I have tried using LE8 and LH1 from samfirmware.
Is there any other full odin firmware?
I'm a little confused here. If I am reading this correctly, the phone works OK except it will not connect to a network and so doesn't work as a phone any more. Is that correct?
If so, maybe you're flashing the wrong thing - you might need to flash Modem firmware not ROM. Now I might be even more confused than I think I am, but it seems to me all the Comms stuff will require the modem side of things to be correct. It's possible I think) to have flashed a ROM that could be incompatible or which corrupted your modem side of things.
Keep in mind I am still learning this stuff, but recently I thought I'd get ready to flash a JB ROM by flashing a kernel that was supposed to be for JB - there were others there with a warning NOT to use with JB so I figured I should get one suitable for JB - long story short I had a non-starting phone and had to work from scratch with PC Odin to get everything working again.
So, I am guessing that the ROM you are flashing also needs a kernel and Modem flash. I'm also hoping if I am wrong someone more experienced will tell me why
My guess is also you'd need to flash kernel, then ROM, then Modem, and make sure they are all to whatever version o Android you are wanting to have.
Am I making sense or am I talking through my proverbial?
have you try to use another micro Sim, it can be micro Sim reader o your Sim.
I got my phone repaired from a third party repair centre,
They used SPT box to repair the efs folder. Now i have signals and it can connect normally.
It cost my $60 for repair.
Thanks to every one for helping me out in the repair.
Hey everyone. The other day, I was installing a custom ROM and was also trying to unlock my Galaxy SIII. After both, Airplane mode somehow locked on... I did a factory reset - didn't help. I also reinstalled the stock image - didn't help. I tried several tar recovery files - didn't work or help. I tried everything! I can disable airplane mode in settings but my device simply displays a circle with a cross through it instead of the signal meter in the notification bar. It also doesn't detect SIM cards now... I don't know what is wrong. Help would be GREATLY APPRECIATED!!!!!
Thanks for your answers in advance!
My first thought is the Unlock process stuffed things for you. What did you try for the Unlock? Did you get it right? I've never had a locked phone so I don't know the process but try asking around on threads where they talk about unlocking phones.
What ROM did you try? Can you still get into the phone for menus etc?
And the biggie - did you try Restoring your Nandroid backup? (you DID do a Nandroid at some point, didn't you? )
If you've only done a factory reset from the phone I'd try getting MegaWipe and flash it in Recovery. Then try a ROM you know to be working for others.
Another thing to look at might be your Modem - I use Purelook HD ROM - one of the updates had a modem that screwed with my wifi and phone connection so I flashed the previous one that had worked well and all was right again.
You might also need to try a megawipe and then flash a stock ROM via Odin - get the phone back to a working state and then start ROM'ing again.
Yeah, I can get into menus alright. The MegaWipe didn't seem to work though Or the Purelook HD ROM. I've flashed the stock ROM about 100 times, restored Nandroid and did a full stock restore however nothing worked. Thanks anyway!!!
Do you have an EFS backup?
Is your modem correct? if not, restore your EFS backup
Another thing, dial *#06# on your phone and look at your IMEI. Do you see a bunch of zeros?

Your EFS is corrupted. If you have a backup please restore it. If not Flash a fresh stock ROM and start over.
If I'm right, you turned your phone to a Wi-Fi tablet. There is not a real at-home solution other than searching your whole computer and your phone's internal memory and all SD cards you used on your phone for files that have "efs" in their names and hope you find some kind of EFS backup you took before. (About that, can you post a list of the ROMs you installed before? I know Sotmax takes[or used to take, don't know the new versions] automatic EFS backups, maybe other Samsung ROMs do too)
If you can't find any, you should contact with your carrier and ask if they can repair it. It won't be covered by warranty, and you would probably be asked to bring evidence(receipt and such) to prove the phone is not stolen.
Make sure you tell them the whole story, and don't try to cover up the fact that you rooted your phone, or you may end up being questioned by the police.
If they accept, they will restore your IMEI using advanced debugging hardware and software. If they reject, then you may want to start looking for a new phone.
(Procedures may vary)
actually, it will be covered by warranty if you restore it to complete stock
They may still look at the binary counter and tell Odin has been used.
Other than that, lying in such conditions may result in big trouble, so if they ask if you have rooted your device, you should say yes. Not worth risking much bigger trouble for a paid repair.
There is triangle away.
Triangle away+flash stock rom = full stock no binary counter.
Why do you say there might be problems with the police? Since the gs2 there have been lots of cases of lost/corrupted efs without doing anything. Are all those people in jail?
If there's proof of ownership, then there's nothing to it. I really don't know how much is the standard rate for lost/corruped efs fixing outside of warranty, if it involves motherboard replacing, its gonna be as expensive as a new phone.
I'm talking from looking at my country's regulations, so they might be different in other countries. Hence the "procedures may vary" in my reply.
Hello.
I really didn't want to make a thread but i've been bouncing of dead lnks and failed search results or outdated incorrect info all day and i can't seem to get the information i need. I'm sorry if i haven't done everything i can before this psot but i have rtied, i really have!
My issue:
I have a Samsung Galaxy Ace GT-S5830i which was running so slow it was terrible. I found a nice slimline rom that i read about and was happy to use.
I used Samsung recovery to then run CWM ClockWorkRec5830i, which i used to install 'update' which gave me Superuser access and rooted my phone (i think, if i understand) then i made a backup of my phones stock image, then i used it to wipe the phone, clear cache, and finally install my new rom.
...so far so good.
The rom installed, the phone rebooted, everything was working (really fast and really well, i was VERY pleased) however i have hit my issue:
IMEI data was gone. *#06# showed nothing, so i went back into Samsung recovery, loaded ClockWorkRec5830i and restored my phone back ro original using my backup. The IMEI returned! All was well again, so i got Galaxy Toolbox from Play store, ran it with Superuser access and created a backup of the EFS file.
I returned my phone back to the new rom that i had chosen and again installed Galaxy Toolbox to use the 'restore EFS' option.
The IMEI is still blank using *#06# which has me very confused.
I can open the EFS backup file in Hex workshop and the serial number data is is there. I can use Galaxy Toolkit device info and see the IMEI in there, so i don't understand what i have done wrong for the IMEI not to be showing in the phone.
Can anyone help or educate me please. I do generally want to learn more about why i haven't realised the mistake may.
I love learning this stuff but it can be overwelming sometimes until someone comes along and calls you an idiot and tells you the obvious lol! Please, "I'm an idiot" hehee.
Thankyou

Don't consider yourself idiot at all lol. You have explained everything so clearly.
Well,
This problem is so much common with this phone. Don't know why !
Many people including me facing this problem.
Sometimes you just reboot your phone and you will see ur IMEI is gone. Reboot again and its back. -_-
Its really strange issue actually.
You already knew all methods to get IMEI back. This is comman issue with this phone. Suffer it.
Maybe @iamareebjamal have figured this prob out.

The rom i found was great. It performed so much faster, did not take up much of the very limited memory on the handset, it was the perfect solution to my needs but whenever i use it i cannot make any calls etc due to no IMEI (*#06# shows a complete blank box) and i have tried rebooting the phone so so many times, repeating the process of installing the rom again and again and not once can i ever get it to show IMEI in *#06#. I could understand if the EFS backup also showed that the imei had reset or become corrupt, but it looks fine in Hex Workshop, shows up in device info on Galaxy Toolbox app, i just can't conclude anything from it's behaviour.
Using my original phone's backup the IMEI is restored instantly, and i have taken the EFS backup whilst running the phone on it's original state.
Could it be because something is not right in the rom? Is the rom changing something that i could possibly correct myself? Or something in the rom not suitable for my model and version of the GT-S5830i handset (compatibility issue)?
I really want to be able to use this rom and other's seem to be able to use it without issue which just makes me more determined to find the cause and correct my issue. I also see that many people do lose their IMEI and the EFS backup/restore method seems to work perfectly for them, because they seem to have their IMEI turned to blank values when checking in HexWorkshop whereas mine is still showing as expected.
I cannot make sense of this scenario at all lol.
I appreciate ANY and ALL advice
The rom is was trying was MEHDI ROM v2. I am in the United Kingdom using a GT-S5830i on o2 newtwork with no network locks or restrictions.
Make a new backup of your IMEI(make sure it is lost by once or twice rebooting) . And open via Hex Workshop.
If you see your IMEI in there, then reflash stock ROM and flash this Custom ROM without wiping anything.
If it doesn't solve your issue now too
Try restoring the efs partition before Media Scanning starts and Reboot the phone after media scanning is started.
These all are hit and trial methods. I've myself never found a fully satisfying solution
If nothing works, you'll have to try any other ROM.

As about these issue i do flash a Custom Kernel after flashing Rom with no IMEI Number
So After Flashing any Custom Kernel my IMEI Gets back
You can try it with any kernel
I use to flash Rafael.Baugis Kernel flash both its Modules and E3Boot.img
may be try changing kernel..
try any custom kernel...it helps me every time..
i have wiered problem, i can't use custom kernel on stock rom...or stock kernel on custom rom, both of these combination makes my imei disappear every time.
go to this thread for all the explanation

Hey, did you solved your problem? i had the same problem once and it was just that the backup made with galaxytoolbox didn't match. So the best solution is to do a backup again and you will have to open the new file and edit it with the HEX editor and input your imei number manually. Here the thread with the info http://forum.xda-developers.com/showthread.php?t=2064034&page=1 and this video is great, but it's in spanish. http://www.youtube.com/watch?v=1kbY0EZYsXE Hope this solves your problem.
I cannot use the galaxy toolbox for my restoring unfortunately as the galaxy toolbox is not working with my current rom, if you know of another program that can help me fix it, i would appreciate it.
Thanks,

Thanks for the replies, but unfortunately i have not yet resolved the problem.
I have gone over the process again and again, repeating it the same way, trying slightly different ways, the outcome is always the same. Everytime i try i take a EFS backup (taken while the phone is restored to running on it's original stock rom and setup, with the IMEI all working and displaying via *#06#) the EFS file shows the IMEI in Hex Editor. Everytime. It's always there.
Then, as soon as i flash a rom and reboot the phone i have no IMEI. I use the good EFS backup and restore the EFS to the phone (which has the IMEI data intact) but the phone still will not display the IMEI via *#06# and if i check the EFS again it is still showing the IMEI as being in the EFS backup and still good.
So i have no idea why the phone is not seeing the IMEI because apparently it IS still there!
I'm installing roms by using the recovery method to 'apply update', using Samsung basic recovery mode, but could i use the CWM recovery to install? Would that have a different effect? Is it safe to use CWM to install roms as the guide i read said to only install roms using Samsung restore as CWM adds a risk of crashing or bricking the phone?
So many people are able to successfully flash a GT-S5830i and i just do not know enough yet about phone roms to feel confident to do more daring things with different methods for fear of making a critical mistake. So much of the information i have read contradicts itself, and other information neglects to explain certain things or simply assumes you know about bootloaders, CSC files and the like...
I've modified so many gadgets before and am fairly confident with doing such things it's just i can't seem to educate myself correctly over the modifying of these Samsung Android phones.
I just bought a Samsung Galaxy S GT-i9000 today and wanted to remove some of the bloatware so that's my next phone to read up on.
I have been put off a bit because of the issue of losing IMEI. It seems to be a big risk with this model, do other Samsung models have issues with IMEI loss?
Thankyou to all who are taking time to post. I read and appreciate every post, and am enjoying learning about this new topic to me.
Perhaps i shouls restore back to my original working setup, then install the rom using recovery (or via CWM recovery - i have no idea which is safest and the correct method as i read conflicting information) then install the rom without resetting/wiping anything? Would that help?
When i select roms should i be making sure they contain a compatible baseband or something?
I don't understand this area.

About recovery use CWM
If you do not wipe then there will some problem occur may be like the phone will not boot after flashing Rom so must do wipe
And about baseband and all don't worry you can use any stock Rom for flashing Roms.

Thanks for the replies, but unfortunately i have not yet resolved the problem.
I have gone over the process again and again, repeating it the same way, trying slightly different ways, the outcome is always the same. Everytime i try i take a EFS backup (taken while the phone is restored to running on it's original stock rom and setup, with the IMEI all working and displaying via *#06#) the EFS file shows the IMEI in Hex Editor. Everytime. It's always there.
Then, as soon as i flash a rom and reboot the phone i have no IMEI. I use the good EFS backup and restore the EFS to the phone (which has the IMEI data intact) but the phone still will not display the IMEI via *#06# and if i check the EFS again it is still showing the IMEI as being in the EFS backup and still good.
So i have no idea why the phone is not seeing the IMEI because apparently it IS still there!
I'm installing roms by using the recovery method to 'apply update', using Samsung basic recovery mode, but could i use the CWM recovery to install? Would that have a different effect? Is it safe to use CWM to install roms as the guide i read said to only install roms using Samsung restore as CWM adds a risk of crashing or bricking the phone?
So many people are able to successfully flash a GT-S5830i and i just do not know enough yet about phone roms to feel confident to do more daring things with different methods for fear of making a critical mistake. So much of the information i have read contradicts itself, and other information neglects to explain certain things or simply assumes you know about bootloaders, CSC files and the like...
I've modified so many gadgets before and am fairly confident with doing such things it's just i can't seem to educate myself correctly over the modifying of these Samsung Android phones.
I just bought a Samsung Galaxy S GT-i9000 today and wanted to remove some of the bloatware so that's my next phone to read up on.
I have been put off a bit because of the issue of losing IMEI. It seems to be a big risk with this model, do other Samsung models have issues with IMEI loss?
Thankyou to all who are taking time to post. I read and appreciate every post, and am enjoying learning about this new topic to me.

I'm not sure if you missed this step.
I did efs backup on stock rom and tried to restore with galaxy toolbox on the new rom and IT DIDN'T WORK....
you have to copy your imei number manually (or directly from the sticker) and once you are in the NEW ROM, make a backup of the IMEI. of course if you open it with the hex editor it will be EMPTY.
Then in this new back up file newly created you have to manually input your IMEI number using the HEX EDITOR.
This should work.

Don't ask the same question in two different threads.
Galaxy toolbox works almost every time.
Did anyone having a similar issue manage to resolve it or can suggest other steps to follow?
I am having the exact issue but for the life of me can not make the IMEI appear even though galaxy toolbox reports it is fine. Here is my post from another thread, before I found this one.
Flashed ROM, all working fine except as above, no network connection (mobile connection). Wifi, etc all working. IMEI is blank when I do *#06#
Have tried
1. reboots, sim out, reboots, etc
2. tried using galaxy toolbox to backup imei/efs and then restoring after flash. nope no help.
3. tried backing up imei and editing with hex editor but the image already has correct imei. galaxy tool box does report correct imei.
4. just tried flashing rafel kernal using instructions but after doing so, phone does not boot past samsung screen.
5. reflashed back to stock room and crap radio still not working lol
so any suggestions? i need a kernel and then one that works with this rom.

Since the above, tried thunderbird kernal and I am still without IMEI.
I would just like to ask. Is it possible, at some point I have deleted EFS partition? Should I be able to see this EFS partition somewhere? Browsing through PC, on SD card or through CW recovery?
My only idea is that I have deleted efs partition so galaxy toolbox has no where to restore to BUT the app itself reports correct IMEI as does the hex value with a backup file.
Ideas, rants and possible suggestions welcome!
Thanks

Thanks Hitesh but I beleive I have tried all the methods. Check my reply here...
I solved my issue by flashing kernel again...see...
my post
Hello everyone.
First i'll tell what i did.
I rooted my phone couple days ago and flashed paranoid android but then i thought that i can do something more with it and tried to flash new kernel, but that pu my phone in bootloop. So i tried to flash original firmware but this didn't work and i was still stuck in bootloop. Then i found on some forum that i can do this through kies so i did flash original ROM through kies and everything was ok (i thought so because i didn't think about that my phone had no range), so i tried to flash Paranoid again and when i did it i saw that i have no range (I had also null or 0049 imei). I tried to flash new radio because i thought that this could be somehow broken. That didn't help at all so i found diffrent way to bring back range to my phone but when i did it i put my phone in factory mode so i dealt with that problem, and i had range allready but my phone still had this "only alarm calls" state. But my phone knows what carrier i have because i can choose from the list in setting but that doesn't help too. Now i found a way to do it (sort of i think) but i cannot change my recovery.
And i have no imei till now (and i didn't backup my efs folder :/ ).
That's preety much it, but i could forget about something or the order is diffrent.
I'd like to go back to paranoid android and to have service and imei
I'd appreciate anyone help with that because now i'm in middle of nothing and i'm like i lost my phone... :///
P.S. Sorry about my language skills.
Hundreds of identical posts, search and read on imei. Restore your efs backup to regain your imei.

You see, it's not that simple because i cannot copy efs folder or delete it. I wrote this because nothing works not because i'm too lazy to do search
