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I really didn't want to make a thread but i've been bouncing of dead lnks and failed search results or outdated incorrect info all day and i can't seem to get the information i need.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.

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,
Fab

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.

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

Hi all,
I own a galaxy s2. I'm facing a issue which i've been trying to fix for the past couple of weeks. I tried many threads in this forum, but nothing seems to solve the issue.
This is the issue,
I used to flash custom roms on my device. I used many custom roms including cm9 RC1 and when samsung released the lastest 4.0.4 update i just wanted to chek it out. so I downloaded the generic russian (SER) firmware and flashed it using odin.
After flashing it I was stuck @ boot. i was stuck there for more than 10 mins, so I ended up removing the battery. then I went to samsung recovery(Volume Up+Power+Home) and cleared the cache and user data and rebooted the phone it worked fine. At this time I didn't bother to check whether my IMEI was there but everything worked fine.
After couple of days(without rebooting the device in that time) I droped the phone. battery came off, when I turned on the device again, prohibited mark like thing came in the status bar and there was no service, when I checked the IMEI it was not there.
At this moment I was not sure whether the drop caused the issue or the flashing caused it. I later realized IMEI issue comes because of EFS but sadly I didnt back it up. After diggin for few days I found when flashing one of the custom roms, efs was backed up automatically, I tried restoring it, but it didnt help (Maybe the backup was corrupted )
I followed various threads in this forum but nothing helped me.
Please help me get the IMEI back, I really miss my device :crying:

I once had a similar problem.
My imei went lost because of a rom upgrade and I DIDN'T have a backup..
I solved the problem by flashing a stock rom (any samsung stock rom will do) with ODIN.
I am not sure what happened, but it looked like that the nv_data folder was "re-generated" and I got my IMEI back.
Now I have a copy of the folder in every storage media around my house

I tried almost every thread here in xda about restoring, tried GSII_repair, kTool to restore it but none of them recovered the IMEI. I did not made a backup of efs but when I installed the Hydra H2O ICS Rom for GS2 it made the backup i guess, because a file called "efs-backup.tar.gz" was in a folder called .hydra inside the sd card.
does the drop of the device has anything to do with the erased IMEI?

I have installed stock roms from samsung using Odin, but then I discovered that efs folder get unmounted everytime I install the stock rom, phone just starts after flashing without android setup wizard, also when I long press power button, menu wont appear, device just shut down, after I restore the efs from the backup i have, and mount the efs using the CWM recovery would bring back the power button long press menu. everything else working except for Mobile Networks. and imei/baseband shows unknown
Drop Caused this problem
Hi all,
Thank you for replying on this thread and helped me figured out my problem, I have contacted Odia and he thinks that dropping the phone damaged the baseband chip inside the main board, not a flashing of the roms or efs folder issue. i have only 2 options either replace the whole board paying LKR 35,000 (New s2 costs only LKR 65,000) or use it as a MP3 player :crying:
Hello!
I have a samsung galaxy SII that has lost all network connection (wifi works though). It's just a check of the pillars and cant either call or text.
When you go in and check Baseband it says unknown. Similarly, IMEI, serial number and all network related stuff.
I have searched and found EFS Pro but it did not work following the wizard.
Is there anyone out there who can help me get my phone working again?
Would appreciate any help very much!
Im running CM9 stable by the way.
Restore your EFS backup. No EFS backup (Gee, that would be a shock. Everyone does those ) either service centre & explain what you've been doing with the phone (and hand over the contents of your wallet to have it repaired), or if you contact Odia by PM (and wait patiently for a reply, do not hound him) he might be able to recover it for you.
Have you tried to reflash baseband through Odin?

Please answer these questions:
1. Did your problem occur after flashing in CWM recovery with your phone charging?
1. Do you have a good /efs backup?
2. Have you ever flashed Siyah kernel before?
3. Post screenshots of Settings>About phone, and Settings>About phone>Status on your phone.

1. I do not know, I got the phone from a friend who had the same problem with it. He ran the phone stock. So I flashed the CM9.1 and after it worked it in about a week and then it stopped working again simply. He bought the phone used so do not know what is done with it before. However, I had the charger when I tried to flash it yesterday, it is something that you should not do?
2. I tried some kind of stock EFS I found, but did not get better for it. Then if you go into the EFS folder in your phone, there are. .bak files are dated 2011 which might be ok?
3.I got it as soon as I get access to the phone.
Thanks for reply!

However, I had the charger when I tried to flash it yesterday, it is something that you should not do?
2. I tried some kind of stock EFS I found, but did not get better for it. Then if you go into the EFS folder in your phone, there are. .bak files are dated 2011 which might be ok?
3.I got it as soon as I get access to the phone.
Thanks for reply!

1. Yes, it has something to do with it. Don't flash in CWM recovery when connected to charger. It's a known bug.
2. I meant do you have a real backup of your /efs .tar or .rar? Check your internal and external SD for anything efs
3. Ok
i have the same problem and have a backup of efs ...it has 5 folders efs,efs-163,198,200,490..i dunno wat to do please help me with this problem thank u
IMEI lost when copying nandroid backup from old phone to new
Beware.
After receiving a new Nexus 5 to replace my cracked but still working one I immediately rooted/unlocked it and then copied my old N5 backup to it. Used WugFresh Tool Kit 1.8.4 to root and TWRP to recover and both phones were at Android 4.4.4 so what could go wrong? (I thought) Somewhere along the way the new N5's IMEI number was lost (=0) and so no service. Tried factory reset and recopying but no luck.
I factory restored the phone and returned it to Google. I expect some penalty for my antics. I will get delivery on another N5 today and will refrain from tinkering for awhile. Fun.
Correction to above: The newest Nexus 5 received today came with Android 4.4.2 not 4.4.4 as I assumed (and perhaps incorrectly) for the new N5 described above. This could have been the deal breaker, copying a 4.4.4 system over a 4.4.2 one, that screwed the IMEI (?).
Initial state(stock 4.0.4. ROM):
Device was working properly;
Could call, could use 3G internet;
Everything was good.
After CWM zip installing FoxHound ROM:
Simptoms:
Could not call; for every GSM/3G interogation to telecom operator I get: "Not registered on network";
In my pursuite to fix this, I don't know how, now my device ended in Factory Mode(a yellow box with some debug information appears on my screen and the power button now instantly shutsdown the device and no lock screen available).
The IMEI returned by *#06# is different by the one on the back of the device. It's not a generic one "000...", it almost looks like the original, both seem to be valid after some search, but this is odd. I don't know if it was different before installing FoxHound ... never cared.
What I've tried to do:
I've actually feasted on half of internet for a solution to my problems;
I've tried to flash with Odin tons of stock firmwares, modems, CSCs, including well known ones, my operator ones(Cosmote), my country ones(Romania) -> no luck;
I've tried to restore previous nandroid backups -> no luck;
I've tried to CWM zip install custom ROMs -> no luck;
I've tried everytime to wipe cache, factory reset, delete dalvik, fix permissions, reset battery stats -> no luck;
I've tried all the solutions for the "Factory Mode On" problem, including "echo -n ON > /efs/imei/keystr; chown 1001:1001 /efs/imei/keystr" -> no luck;
I don't have an /efs/ backup before installing FoxHound.
Used GalaxSim, everything was green, no unlock needed.
My device is still in the same condition. No one has an answer. Do you have a solution?
Have you tried flashing with mobile odin?
How did you do a nandroid? With s3 toolkit?
Sometimes when it doesn't work I have to re install the samsung drivers and then try again on full charge.
Something else I noticed with the toolkit was that if I choose a different firmware from the options I done the nandroid with it doesn't work.
Also you may have to flash the insecure image again.
Sorry all could think of.

1. I haven't tried with mobile odin. This is the first time I've heard about it. I only used desktop odin for flashing.
2. I did a nandroid backup of the stock version of my device, the one which was functional, but without s3 toolkit(also the 1st time I hear about it). My curiosity is why it still wasn't unable to function after I've restored the functional nandroid.
3. I'll try this, thanks.
4. Never heard of insecure image. I'll search for it. Thanks.
5. Thank you very much for your reply. I'll keep you up to date if I'll manage to repair it.

Sad ...
Your EFS data is fu**d and your modem refuses it (and refuses to let you on the network). As far as I know running with an invalid IMEI is illegal in every single country, and in most can land you in actual jail. That being said - search the post about ariza (who had the original modem patch post, but decided to go on a different way) or download this - http://db.tt/PDH8Bc64 !
IMEI broken restore your backed up EFS folder .

I don't know why my EFS ended ****ed up, and yes, it's illegal. AFAIK, if it's a soft problem, it can be fixed. Isn't the IMEI code embedded into the hardware? Why can't I just wipe everything, from /, and flash a stock ROM? The EFS should be fixed, right?

This is important for me, please follow:
I have a nandroid backup of my working stock ROM. Does this backup contain my working EFS? Note that I've restored it, and I still get the network error.

NO
No EFS backup in a nandroid .
Rule one is backup your EFS folder .
If you have a custom rom or kernel that may have auto backed up your EFS to a file efs xxxx.tar .gfz
No EFS then before a service centre try .

IMEI is no longer so much in "hardware" - it is stored in a protected way in nv_data.bin, which is located in the EFS partition and under normal circumstances is NEVER written by a ROM. Unfortunately the normal nandroid backup does not contain an image of the EFS partition, but some of the better ROMs create a backup (sometimes on the external SD card, sometimes not) - look after something called efsbackup.tar.gz or efsdev-mmcblk0p3.img.gz !
Also the IMEI and serial number from under the battery can (and should) be placed back in a form of edited nv_data.bin - but most likely you will never be able to run that with any of the stock modems and you will still need the patched one that I linked somewhere above.

Thanks for the info. Good to know.
Finally, my device works. I've contacted a private service.
The Factory Mode problem, which was always on, was fixed by flashing a stock 4.0.4 ROM.
The "Not registered on network" problem had various reasons:
My IMEI had been changed so my modem wasn't accepting any calls. He had rewritten the original IMEI(the one from the back) with "the box".
For unknown reasons for me, 4.1.0+ has some built-in protections and will brick my device everytime I flash it. So, for the moment I'm sticking with 4.0.4.
Some people experienced this problem after updating, so it has something to do with the built-in protections(but the question is "protection against what?"). There's something smelly about our IMEI, we, the ones having this issue. I've bought this device over ebay.co.uk and it arrived unsealed(the merchant told this because he had to check the phone) but with root installed and had 1 count of custom binary flashed, in the download mode screen. This is odd. From now on, I'll ask for IMEI.
I thank everyone for helping me. Best regards!
Stuck on EDGE and in Factory Mode
I have literally over 16hrs trying to get my I747 back working correctly. It all stared when I tried the "Hellfire" rom. I have had my phone rooted running custom roms for over 6 months with no problems. After flashing the "Hellfire" rom I noticed that I was stuck on "EDGE" network, unable to make or receive phone calls or text. After further inspection, I noticed I had "0" for an IMEI#. So I injected my IMEI back on the phone... Still the same problem. I reverted back to stock ROM, Kernel, and Modem... Same problem stuck on "EDGE" network. Several hours later of no stop research, I noticed that my "ERI version Not available". After alot more research I noticed that my "efs" folder was missing the ".nv_data" file. So I backed up the "efs" folder, saved it to my extSD, and then deleted the "efs" folder for the root of the phone. Now I'm in "Factory Mode" even after replacing my backed up "efs" folder with the new one that was created at the root of my Internal sd.
I need help... If anyone has any ideas...:crying:
You might try what they talk about in this thread, don't know if it applies to your situation or not...
I can't post off site URL's, so google "Not registered on network" + stuck in Factory Mode ON - no solution works
It's the thread on androidpit dot com
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?

When I dial *#06#, a box pops up and simple says "IMEI". There is no actual IMEI number displayed... That must be bad..??

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 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.

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
