Is your IMEI correct ?
If not you have a corrupt efs folder
See multiple EFS recovery posts.

You can't simply "get" an IMEI. You need a backup to restore it.
Another way would be if the encryption algorithm becomes public, so you could simply restore your old IMEI by rebuilding the appropriate files.
From what I know the algorithm is still unknown and as such you will have to rely on a backup, speak with the guy who sold you the phone.
Btw:
Samsung could restore it, too, they can simply rebuild the files (aka encrypt them properly).
About the backup part, this thread might help:

Hello, today I got a live demo unit from Samsung, but it's a small problem, in this device, it is not possible to use the phone part, it is possible to fix this? phone is not locked, and the sim card is in working, and all apn is i order, but it wont register on the network.
NEW INFO!
My phone is "out of service" and i cant turn it on, so i can use it.. can some one please help me.
the raido is working, becasue WIfi is working, the same with thew bluetooth, so it seems to be loocked for use of sim cards.
please help me some one?
my imei is a very strange imei starts with 00499................
Hello Jespersen84. Seems like i9300 live demo units don't have their own IMEI (they all have the same) and the EFS folder isn't complete, some files are missing.
You can use everything, except phone calls, sms, mms and 3G data.
Thats correct,
but i was hoping it can be fixed, maybe change imei, or is it possible to copy the files that are missing to the efs folder?
i have tried to root it, i have installed new custom rom, nothing wil work, i thing i have to cange the IMEI to get it to work.

Change IMEI is illegal and against XDA rules .

Closed, as changing, and discussion changing IMEIs is illegal, and against XDA rules.
my gf lives in another country atm and i cant put my hand on her phone, that atm isnt rooted and still on gb.. she had a prob on her sg2, we were talking on skype we ended the call and suddenly she lost all connection to networks and seems the phone using *#06* doesnt show any IMEI.
any chance i can restor it? i dont have any bkup tho.. but ive seen somewhere that ODIN has a feature to clear EFS folder and android reassign a new IMEI..
is that true? is it working? this thing will kill the warranty from samsung?

without copy of the EFS folder it may be difficult. did you read this:

As gaeilge pointed out, without a backup it may be difficult, but you could try this tool here: https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool&hl=en
Or this one: https://play.google.com/store/apps/details?id=com.helroz.GSII_Repair&hl=en
If all else fails there's a dev on this forum, that for a small donation maybe able to fix the problem for you!
Try search efs/imei problems!
Hi there.
Hope someone can guide me on this. I've been reading all the posts related to unknown imei, lost efs folder, etc and tried several things to solve the problem, but anything worked out.
The phone got wet with some raindrops (very few raindrops). Warranty was lost because they told me the motherboard was damaged by water. At first the battery exhausted in no time and it didn't charged properly, but a couple of months later everything seems to be all right except that it tells there's no IMEI, and the SIM card isn't read by the phone. Later on I've brought it to another technical service where they've told me the motherboard wasn't damaged, but the SIM connector. They wanted me to pay a big amount of euros for such a little piece. I picked up the phone and decided to investigate by myself.
The actions done to the phone: I fisically opened it and applied a connector cleaning spray; then I upgraded it to ICS and finally rooted it. Then I tried lots of solutions that are posted in the forum, like the GSII_repair, busybox, backup of the efs folder via android-sdk, efs pro, etc.
The only thing about efs that I can read in the phone are two files: an efs.tar.gz and an efs.img.
The efs.tar.gz seems to contain everything needed to restore EFS folder: nv_data.bin, nv_data.bin.md5, etc.
I have no idea how to tidy all this mess up. I know that it's possible that the phone won't work again because of the rain, but I want to sold all the possibilities out before using it only as an ipod galaxy, and I resist thinking that if it was damaged by water the phone woulnd't work ok like it does.
What do I want? Trying to give it its IMEI number again and seeing whether it catches signal. Any idea on how to do that with the files efs.tar or efs.img.
Thank you so much.
Since you have some kind of an EFS backup, then you can use kTool, in the Google Play Store, to restore that backup.
kTool requires root.
Hi and thank you for the reply.
I've downloaded this hc-ktool and tried to restore EFS from backup via efs.tar.gz and via efs.img but anyone worked out. It still says "unknown IMEI". Any idea about why it didn't work?

Not really, I am still a noob in Android.
Do you have unknown baseband problem? If yes, then try flashing another modem via Odin.

In the baseband section it tells UNKNOWN, as well as the telephone number, IMEI, IMEISW and Bluetooth. D'you think changing the modem will change all the other unknown stuff? I'll try it anyway, thanks.

Nothing to do with the modem. I changed it and everything's still the same.
Still rounding the problem... I installed root explorer and I saw there is an original efs folder in the root of the memory, not in the internal sdcard of the phone. So, what can the problem be? Is the phone really damaged? Or do someone think is only a software matter (is the efs folder corrupted?). Anyone can help?

Hello, a few days ago I dropped my Samsung Galaxy S II in a small bucket of water. I immediately took it out, pulled battery out. Waited for it to dry up (used hair dryer) pulled battery in and ... well it worked ... sort of. Everything worked apart from WiFi and USB connection (i.e. PC does not recognize mobile) which is not that important, most important was that I could phone.
I did make phone calls and I did receive phone calls. Then I changed the simcard with another one (I was abroad when the accident happened so abroad I use one simcard and at home I use another one) ... and I got no service. I put back the previous simcard and still no service (note: both simcards work in other mobiles).
Then I realized that pressing *#06# I get just a message box with 'IMEI' written but no IMEI number (not even a default one, none). From the mobile settings (Settings > About phone > Status) I can notice that IMEI is unknown and IMEI SV is unknown, Baseband version is unknown as well.
I tried factory restart (a few times now)
I searched on the internet. Installed Framaroot to root mobile (as mobile was never rooted), installed Root Explorer and Terminal and followed a tutorial that basically asked to make a copy of EFS folder, delete original EFS folder, reboot, copy .nv_data.bak in the root EFS folder (from the copy), rename this to nv_data.bin, copy imei folder, etc.
This did not work.
I also tried to BusyBox and GSII_Repair but GSII_Repair does not manage to repair either (i think because at this stage by EFS folder is already doomed).
What I noticed is that in my "imei" folder in the "efs" folder I only have three files and none of the files have an imei number.
So my question is: does anyone know where the imei number is stored?
or if there is an app that simulates an imei number?
Mobile looks ok (I can literary do anything apart from phoning and browsing internet).

I did follow that link but did not solve anything for me. Step 6 says to make another copy of the ".nv_data" file but I have no such file, the file I have is ".nv_data.bak" ... is this normal? I am afraid by copy of EFS is also corrupted as I did it after the problem appeared and after I had factory reset the mobile the first time.
Edit:
Also the default EFS folder I get generated after the reboot does not have all files I have in the backed up EFS file (for example I do not get nv_data.bin.md5)
Can I copy the efs folder from one mobile to another (for example from a Samsung Galaxy ACE to the Samsung Galaxy SII)??
The .bak file is a backup of your previous file
Rename it to remove the ".bak" part and hope for the best.
BTW - water damage is very serious matter. I suggest to remove the battery, SD card, SIM and put the phone in a jar of rice (completely covered by rice) for 48h at least. Rice will absorb all moisture from the device.

Thanks for that info ... will try that hoping no permanent damage has been already done.
Just another quick question: I am afraid that my copy of EFS folder is also corrupt (as this was done after the accident and after I had factory reset). Is there a way how I can set this up in memory AFTER the mobile is on? or can I copy the EFS folder from another samsung mobile (I bought a Samsung Galaxy ACE as a replacement and was wondering if I could copy the EFS folder of this onto my Samsung Galaxy S2)?
Factory reset does nothing to IEMI files - it deletes all the app settings and app data.
Focus on restoring your original efs. I'm not sure that SGS2 and Ace are compatible for efs "transplant". It's worth a shot (after backup).

I can check if someone at work has a Samsung Galaxy S II like mine and is happy to give me a copy of his EFS folder. That should definitely solve the problem if my problem is with a corrupt EFS folder right?

No it won't work. Take it to a local mobile shop and give them a small fee and they will fix it. Also water damaged is not good as stated above.

Thanks for your answer, just out of curiosity ... why wouldn't it work?
Because the IMEI is a unique hardware identifier I.E one IMEI for every mobile device on the planet, his EFS folder contains details pertaining to the IMEI attached to his phone. Even if you could do it, you'd end up getting both IMEI's blacklisted rendering both phones useless (good luck getting them unblacklisted).
Pay the small fee as advised to have someone fix it.

This is not about paying a small fee, I actually already bought a new mobile. I just would like to try and fix it for the fun of it!

I understand what you mean ... but ... if I do the copy of the efs folder, remove simcard, turn it on, enter *#60# then I should see the same IMEI number as the one of the other mobile without blocking the IMEI number (as there is no simcard). Then all I would have to do is see how to replace that IMEI number with my IMEI number by using the steps suggested in the second post.
It won't work because the IMEI is baked into the hardware. You're thinking about it in a simplistic way, and it doesn't work like that.
You're venturing into rather dubious territory discussing changing IMEI's, which is forbidden here (because it's illegal, even in the manner you're suggesting), I suggest you steer away from that, lest mods close your thread.
Your phone can be fixed (the IMEI/EFS can be re-written to the device), but it requires specialist hardware to do it, which you can either pay for & stumble around to try and learn how to use it without permanently borking your phone, or you can pay someone who already has the equipment & knows what they're doing 20 quid to do it in 10 minutes.

Do not want to be doing anything illegal. I will follow your suggestion. I bought the mobile as part of a contact from Vodafone (no longer under warranty) should I take it to them?
Note: USB does not work. I can charge it but PC does not recognize it. Would an IMEI/EFS re-write still be possible? or I am better off finding a motherboard over ebay?

Yes, you must be right. I though IMEI was stored in a file not burned on a chip, can't understand how the hacks i found on the net work if IMEI is stored on a chip.
No. They'll send it to a Samsung service centre (like Vodafone do here) & they'll charge you an arm & a leg to fix it. Ring around local mobile repair shops.
In that case it might need a USB port replacement, which is cheaper than the IMEI fix (you could do this first yourself, then pay to have the IMEI/EFS fixed) if you do it yourself. There's been a bunch of threads on here over the past 12 mths, search for/read those before you do it, you need to order the right part & there are 4 revisions.
A motherboard replacement with a board sourced from a 'donor' phone/phone with a broken screen which is otherwise OK for example is doable & relatively cheap compared to having a service centre put a new motherboard in (your IMEI will change if you put a 2nd hand board in which is OK/not illegal or anything)
The EFS stuff relies on the the stuff in the chip not being scrambled/corrupted (which invariably happens in these situations).

Thank you very much for your answer. I will take my chances and open it to see if I can fix the USB. After that I hope to find a repair shop that can re-put my IMEI back on the mobile.
Thanks again.
Hello all, GREAT NEWS! I opened my Samsung Galaxy S2, was going to remove the main board when I noticed that a connector with label JB55 looked like had some corrosion (not sure if that is what its called), just brushed it a little, re-connected, a pop, I had my IMEI back
However I noticed that reception is low, just get one bard where usually had three. Does anyone know what module determines reception?
Still not working is USB connection with PC (I will replace that USB port) and WIFI and Bluetooth! ... but hey I can phone
