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 tried this also, but it didnt solve my issue :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

If you have a backup, then you should be able to recover it. There are tons of threads on here with instructions on how to restore an EFS backup. Search (if you want it fixed, that is. If you don't want it fixed, keep posting to this thread in the hope someone spoonfeeds you. Might be waiting a while tho).

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 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.
Click to expand...

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

I solved my issue by flashing kernel again...see...
my post
Hello all,
I tried to stop myself from creating an user and also from starting a new thread on XDA, but i find myself in a bit of a huge mess.
I have a Galaxy S2 I9100G. I find it is an awesome phone, sadly not in the state i have it right now.
I have flashed a CM 10 ROM on it.
All i did is install a modified zImage that had a CWM in it using Heimdall. (It went well)
I have then made a quick backup using CWM and then flashed the CM 10 zip yet again using CWM.
I have then installed an Omni rom using the same flashing with CWM method.
This also went well.
I had to revert to CM10 cause i disliked the Omni rom. After some time (a week or so) i had to revert to the backup cause there was some data i needed, that i had saved in a note created on the stock rom. (This also went well)
After the data was saved i went back to CM10. (This also went flawlessly).
After a while (a few days) i cleaned my phone a bit. After assembling it and starting it up, the signal was gone. At first i was thinking that it is the place i liv in. This sometimes happens where i live. After a while, i came to see that there was no signal nomater where i was. I dissasembled the phone, thinking i might have done a mistake in connecting something back, all was connected back well and the phone still did not have signal. I came to see after playing around with the options that i have had no IMEI and no Baseband version.
What i tried was the following:
Booted to recovery:
in CWM i immediately flashed the created recovery. I have had no IMEI and baseband.
I then found some forums describing the deletion of the nv_data.bin+nv_data.bin.md5 files and renaming the .nv_data.bak to nv_data.bin and letting the md5 being created for it.
I deleted the data from /efs and then let the phone recreate the whole thing from scratch, all i did more was to copy the IMEI and .nv_data.bak file which i renamed to nv_data.bin
I then tried to flash the /efc with a zip file in CWM still to no avail.
I then tried the k-tool from the play store still no success.
There was a tool i found, NV writer tool, but that required for me to set the phone in Qualcomm mode, which was not an option for an I9100G with Texas Instruments OMAP processor. Still i tried the procedure, but the staps where i should have set the phone skipping the set to Qualcomm mode step (the *#something#* code was not working), and the app could not connect to the phone, so this was a stillborn solution for me.
I downloaded (kernel + rom), another stock rom (4.0.4), with Odin and repeated the process described above.
No imei and no baseband still.
I flashed the whole thing also i flashed the kernel again and the rom (this time i went back a step, to 4.0.3), also i used a PIT file for the SII i9100G model, and i did lfash from the a3 recovery mode the zip with the radio. Then i used a software, with the kind help of a friend, called Simlock Remote Server, where i have used a baseband + IMEI repair tool which was targeting my EFS partition and also it was flashing a stock i9100g EFS image. I have initiated quite a few of the of the operation mentioned before with the reair using the EFS image and also then i used another builtin functionality which could write the IMEI and baseband, still with a total lack of success.
I was sort of thinking that instead of an awesome phone i have a wery capable ipad, as all but the GSM functions were working. Sadly i have to say that i find myself in yet another problem. After flashing around 300 or so MBs are used on the system partition, where the rom resides. but after a while i notice heavy battery usage, even when not using my Galaxy S2 "iPad", and also the system partition is getting ever more full, till the whole 2GB are consumed and everything ceases to function. A factory restore with *2767*3855# solves the problem, but this will stard happening again after some time. I was thinking it could be a virus or something, as i have my phone rooted and installed a massive amount of applications which claimed miraculous IMEI repair abilities but failed miserably to deliver. I have installed 4 different anti-virus sw and these did not detect anything.
I am getting a bit scared of making this little piece of HW an useless transistor box, any advice and help would be appreciated. I am really ready to try anything, whatever platform Window$ or Linux may be necessary, please don't keep any possible solutions/suggestions from me.
Many thanks!
Hey, messed up my phone and could really use some help:
I own a Galaxy Note (GT-N7000). Suddenly the IMEI went null/null and baseband unknown. Tried many things to recover from this but nothing seemed to work. I left the phone with the latest stock rom (Jellybean 4.1.2)
I then installed EFS Professional (rooting the phone first and installing BusyBox) and could connect to the phone with EFS Pro. I tried doing baseband and IEMI repair, and though the log showed it had successfully restores from .bak files in /efs partition, IMEI and baseband were still null.
So then I totally screwed it, hitting the "format EFS partition" by mistake (it was 3am by then) and didn't make a backup first. The phone wouldn't boot, so I flashed the latest stock rom again and now it continually loops when showing the Samsung logo when I turn it on. I can turn it on in download mode and recovery mode. When on recovery mode, it says /efs partition not found so I guess that makes sense.
The question here would be: is there any way I can fix it without sending it to service? Some options that sound possible:
- Flash the phone with some other custom ROM that would repartition the whole phone, thus creating an /efs partition again
- Use some nice software to recover the /efs partition
I'm sure that if a service can fix it, there should be a way I could do it as well.
I know my IMEI number (it's in the sticker on the back of the phone) so there should be a way to restore it into de efs partition, right?
Thank you all and forgive me if I've made some noob comment on this post...just doing my best

something like a stock odin flash would fix it: http://forum.xda-developers.com/showthread.php?t=2261598 as long as it flashes a pit file
then once that works, see if efs pro will let you manually set the imei.
if not, then make sure you are stock, and make sure you use triangle away or something and then send it in.

Whoaaaa You should STOP ASAP! You can't flash the AT&T firmware via Odin since you have the international version.

I'm from Argentina, this phone is from Movistar carrier. Right now I have the latest stock rom from Movistar flashed, but the rom available does not have any PIT file, so I can't get my efs partition restored and the phone does not boot in normal mode (only download and recovery mode).
As far as I can remember, any phone that works with AT&T in the US works just fine in Argentina with Movistar. I've brought some iPhones from AT&T (not unlocked) and they worked without a problem.
I believe that I have the international version, but what could happen if I flashed the AT&T stock rom?
Thanks!

It's either going to fail at trying to install the modem and do nothing, or it'll make it worse. In no way is it going to help anything.
You should be able to find your firmware here:

Thanks. I had already downloaded the Movistar stock rom from Sammobile and this time I tried flashing it (using Odin) together with the PIT file and though it said something in the result log about using pit file for mapping, result was the same...still stuck with a bad efs partition that makes the booting loop again and again...
Any thoughts? How can I fix my efs partition? Any help is much appreciated.
Not sure there would be much more to do on your own without the official backup without special tools like SPT, Octopus Box, SRS, etc, but those cost more than the phone, so would have to find a shop that has the equipment and is also competent at using them. Many of the major software tools have repos with files like you need and the correct way to load them. I'd love to have one for my shop, but requests to fix stuff like this don't come often enough to justify the expense when there are more pressing matters...
On another forum they were saying that you can use the efs backup from another clean phone because it does not actually contain the IMEI, so if you could find one of those... I tried to download a couple for you yesterday to test but they either failed to open correctly or didn't pass the md5 validity check in Odin, which is why I didn't repost.
I didnt mean flash the rom I linked. That was an example. sorry guys.

Desperate times call for desperate measures
I'm still working on restoring the /efs partition, even with a null IMEI, at least to be able to use the phone with wi-fi for other purposes (if I can't find someone to flash a good efs.img and restore the IMEI completely).
Right now it's still a brick. Will post update soon.
Thank you all!

Hello everyone,
First of all, I am apologizing if my problem was somewhere on forum, i have searched but didnt found anything similar.
I have rooted i9300, and tried to put Imperium KitKat v3.0 firmware, (without previously backup) and i have successfully done until one point. Phone is on, but without any network signal, no sim detected. Then, i have searched the forum for the problem, and found that IMEI was lost, and the problem was in EFS folder. Found one tutorial how to correct a mistake, but i failed in it, and the phone is at this moment without "nv_data.bin", "nv_data.bin.md5". After that, wandering the internet, found another tutorial which says that the sammobile . com have a lot of factory firmwares, and I think ive found mine (t-mobile germany). Downloaded it, tried to put with ODIN via PDA (auto reboot and f.reset time checked), successfully done, and.... while phone turns on, it only comes to the SAMSUNG logo, led switches between cyan and blue, and stays here. System wont boot. Could you help me how to awake my phone?

have you tried data wipe after flashing from odin?
Thank you, thank you, thank you... Im pretty sure that i've done it and before, but it wouldn't got up. This morning, when i've saw your post, i have done it as you said, and OMG, it worked. :good:
I will use this opportunity to ask one more thing. Is it now possible, to put Imperium KitKat v3.0 firmware, but this time not to erase IMEI and EFS folder?

How did you recover the efs folder? Did you have a backup? I´ve installed lots of ROMs but its still not working. Please please please reply and help me with this. You already know what it feels.

I´ve done that but i couldn´t recover it.
You should make a backup this time if you want to change your ROM again.
try to manually erase those two files in efs folder, then to reinstall rom. nv_data.bin", "nv_data.bin.md5".
