First off I already read everythreads with the keywords : "Fake imei" "corrupted efs" "0049" "00499901064000" "generic imei" "Imei problem" etc ....
I tried theses methods : http://forum.xda-developers.com/showthread.php?p=17587351
http://www.youtube.com/watch?v=iY9cDkj4CCw
delete nv_data.bin and nv_data.bin.md5 and reboot
I also tried to use another ROM but nothing is actually working.
Full story :
July 2012 I buy a SGSII from a woman I just met (yeah stupid but it was only 200€ so ..) it works like a week and then the network problem, it seems that this bi... had a anti-theft insurance and reported the phone as stolen (she gave me all the documents) so they blacklisted the IMEI and the phone was unusable. I then rooted the phone, and deleted nv_data.bin and nv_data.bin.md5 wich worked because i had connectivity, i used the phone for like 2 months and then the problem showed up again, blacklisted (i think) so i managed to make it work again by installing a new ROM and then doing the delete it worked again for several months. And now 2 days ago my IMEI got blacklisted (or some****) again. Tried deleting > nada, tried using a new rom (Cyanogenmod 10.1.2) and then delete > nada, doing the 2 methods listed above > nada. I don't really know what I can do, i just wasted 200€ and now my IMEI is 00499901064000.
I really need your help.
PS : As said before I make this thread because everytime the Imei problem is related to a ROM fail or corrupted EFS files. But my problem is that even if i fixe the problem it will be back in a few months and it will be harder to solve.
PS 2 : Excuse me for misspellings, and if it's not in the right place.
I see your problem, but that link is related to get your imei back.If you get yours back then it is blacklisted....lol.The only way is to keep using the "temp" one or contact the company that blacklisted it and see if they can help.

Yeah I know that but i was thinking, if I get back the old one, the original one,maybe i can delete theses two files, and make it work again, like going back to the first time i solved this problem.
Already contacted them they said they can't do anything.
And my actual IMEI is a 0049 so I can't connect to the network.
There's nothing you can do about it if the carrier won't unblacklist it. That's pretty much the end of the discussion. Chalk it up as experience.
OMG OMG OMG
I just found my first save of my EFS files.
I replaced the actual EFS folder with my very first one and it worked, got my first IMEI back, and i don't know how but it's not blacklisted anymore
Thanks anyway guys

Hi
i was a happy customer with my SII, which i brought from india, everything was fine, until a week back, when suddenly my SII shows no signal, no IMEI and no baseband
i didnt flashed or changed anything ...
1. i tried using different SIM - no use
2. this sim works in other phones
3. factory reset - no use
4. all is done...
**** I DONT HAVE A EFS BACKUP ***********
please give me a detailed fix route for this issue. as i cannot take the phone to INDIA in next 4 months to get is repaired. i have my warranty still. but thought that something can be done from my side to get it fixed. please please lemme know how to fix this! :-(
I had this happen to me. I hadn't taken an efs backup and thought I was screwed, but I found an auto backup on my SD card called EFS_BACKUP. Check if you have this, if you do, use GSII_Repair from the market to restore it.

I tried already flashing the Stock ROM once, and hence i dont know whether there is still a backup of EFS is in place....
can anyone take a little bit more time in explaining the steps to solve this,
like does a backup from another gSII will help the purpose... ?
please let me know more details, i will be thankfull like anything.
How come this problem happens, when we do a complete flash does the EFS folder get replaced or the the flash doesnot affect the EFS part at all?
i feel its very strange to see such kinda problem..
buying Z3x isnt a good idea

what you call its as total screwed??
Will a backup from another Samsung Galaxy SII work ? for me?
EFS is a folder would be having NV_data and some other files. he's asking that the entire EFS got screwed or just some parts.?
I tried complete flash, means baseband,Kernel and system including User data reset.
i really confused about the relationship between the EFS folder and the IMEI,basband, blah blah...
EFS folder is nothing to with your blah blah nor your modem /baseband .
It is essential the details of the phone and its sole identity that is signified by the IMEI number individual to each phone . This IMEI number is used in the initial handshake each time you make a connection .
Lost or stolen phones can have their IMEI blocked once on the block list handshake is denied by the networks = no connection .

GSII_Repair tool from Market, Four steps in that tool, am Done ...........all is well now.
Really really helpful tool. Thanks to all who suggested this TOOL ;-)

u mean is that a nw problem? nothing to do with the phone?
its really p***d off me for fixing that issue..
handshaking happens only after the phone detects the sim card. but here phone doesnot detect the sim at all. so is ur point still valid?
my phone was brought from samsung authorized dealer so how come its possible to happen so?
looks like EFS is the area where full flash no longer having access to it!! if not then a complete flash should have sorted that out.
EFS are reference files containing the imei and phone unique info, when these files gets corrupted, then phone will b helpless.
though u have root access u'll never get RW permission inside the folder.
there should be a automatic recovery, the SW should have had in place if there are corruption. poor implementation.... bah...
My previous phone was Walkman W8 and i used to root the phone and install custom rom and stuff and i was using the custom romed phone for a long time..
Then i got Samusng Galaxy S2 GT-I9100G and stared custom roming and rooting stuff.. After losts of soft bricks and hardbricks i managed to install rootbox rom with codeworkxx custom kernel in it..
But when i booted the the phone then the phone didnt detect sim card i tried restoring to original OS it sill didnt work..
Then i came across efs problems in xdaforums.. So i tried to use efs pro v1.7.14, backed up my efs and tries to restore them.. It didnt work then i downloaded a efs.img online for my phone and tried to restore my efs with that.. I didnt work also..
I tried to restore my backup and efs pro showed me this error...

take it to warranty
I have the same issue and i made lot and lot of reasearch about the EFS folder, IMEI recovery, etc etc, and i concluded that if you still have warranty return the phone to stock and take it to warranty (mine is with samsung warranty since yesterday).
I'll update you if they could fix it.
So I guess there is no other way then..
Anyway thanks for the reply.
My flash count is 7 will they accept my warranty if I restore the phone to its original self and give them...
Is there Anyother Way using Odin to repair my phone..
Badly want my s2 back
OK. I looked here and there and got my efs folder back...
But still my Sim dosent work and also have a problem with baseband version, my phone says base-band version unknown..
You need to flash another modem, but before that enable Flight mode.
Well if you still want to put your phone in Samsung for warranty flash an ICS ROM and then use Chainsfire Triangle Away application to reset your Flash count.
That way you wont have problems with Samsung.
You have the application in Market or in a post in this forum, market its 1.75 € if you get it from the forum its free.
Guys thanks for the replies...
:fingers-crossed:
But some how i got my S2 to detect my SIM card by flashing stock modem..:good:
The modem that worked for me was DZKL3 stock modem... now my unknown baseband is solved.. And my phone detects the simcard but still not perfect have lots of bugs..But even though my cell detects my sim card when i try to call or sms i get "Not registered on a Network" warning...
Now i am stuck up there....What to do from here
Have you tried to switch operator in cellular networks settings?

Is your IMEI 004999010640000 ? Whatever you do, don't post your IMEI (important) if it's different from this, a yes/no answer will do.

YES!
In that case you have the generic IMEI. Your original IMEI is gone. Sounds like your carrier blocks access to devices with non-unique IMEI's (lots of carriers around the world do this; some don't).
Restore your EFS backup if you have one (lots of threads on here detailing how to do this), if you don't have one it's either a service centre job (which you'll probably end up paying for), or you can contact a member on here called Odia by PM who might be able to recover your EFS/IMEI for you (for a small donation; much cheaper than paying Samsung/an authorised repairer to fix it).
Thanks Mate:highfive: this helped me a lot! Hope this solves my problem...:victory:
Sorry for posting this again...
I think i already know my imei number so is there anyway that i can restore my imei number through terminal, or using an external application....
If so can u guys help me... Thanks...
Without an EFS backup, no. Only Samsung/authorised repairer can fix it (Odia can sometimes as well with whatever form of magic he uses to recover them).
IMEI's are a unique device identifier, I.E your IMEI is unique to your phone. Changing IMEI's or transferring them to other devices is illegal in most jurisdictions throughout the world.

I didn't say that. I mentioned it because whenever we get these threads on here, the conversation invariably turns to 'can I change my IMEI or transfer it to another phone', that's all.
You only have the two options. I'd recommend you contact Odia via PM & be patient.

there was a post to recover imei
but now i cant find the thread in gs2 forum
Hi friends, I have a Gt-I9300, I went to Mexico, Panama I used it, perfect, I come back to Venezuela, I change the SIM card and the phone signal is lost, I don't have a real imei, I have a fake one.
Additional, some times the phone show me a message like "factory mode".
I already try to recover EFS, work some tutorials, but nothing. I tried to change the Rom, and install the last one in samfirmware (Android 4.0.4, I9300XXBLFB in PDA, I9300PHEBLG1 in CSC) and nothing happens, still without signal and imei.
For your help.

Why do you want to change your IMEI. Unless it is stolen/lost and reported as such to the authorities which have it blocked?
Note: The OP is asking how to recover from losing their IMEI, not how to change it.
To answer your question, send it back to samsung under warranty and they will fix it.
Sorry its the
I don't have a real imei, I have a fake one.
thats slightly confused me fake as in user faked .
OP
Possible the Sim is faulty .
Additional, some times the phone show me a message like "factory mode
Thats rather odd and i would certainly say also return to Samsung .

No I don't want to change the imei, the phone is showing another imei number. It's not my imei number.
It's not stolen or reported. Just is not showing the imei on the box, or in the back of the phone.

Unfortunatrly your phone's EFS storage got corrupted.
Did you flash a custom ROM? It shouldn't get lost by itself.
The only chance you have is to return it to the seller andmake a warranty claim.
When you get your next phone / fixed phone, root it and backup the /efs partition. That way this cannot happen to you ever again.
by a accident i deleted my EFS file etc. when i was flashing a custom firmware. Then my phone was working correctly except my GSM.
I searched all the internet and i couldn't find a way to take restore my efs. Than i went to a local telephone technical service in my town and he fixed my phone. But i didn't realise he didint use my original imei. I used the phone a several months then suddenly my phone's gsm didint work. So i controlled my imei and it was "004999010640000". And now i need to change my imei number to my original one. How can i do that? i tried "IMEI MAKER/MP0B_001 file method", "MtkDroidTools" and "MauiMETA 3G" and also some other programs. They worked but specially IMEI parts didnt work.
So i need your help. If its a illegal thing. Just PM me. I didint do anything illegal an i need my phone back.
hi my old friend sorry to hear that some technicians used "bluebox" for restore and attach imei. i dont know any idea :/

IMEI is send over your carrier database, they check all IMEIs over network, your IMEI probably was banned because used IMEI number from someones lost or stolen phone
Messed up with my G925F!!!
Hello , my phone suddenly was not able to make or receive any calls or joining 3G/4G network or SMS. In other words, I was out of service although my SIM had not problems to enter the PIN password and I could see signal bars.
After a little research I discovered that my IMEI and S/N number had been changed! Especially, the IMEI number became 350000000000006 (fake one) And I believe this is the reason my signal went off!
So , I just managed to download smart switch from samsung and choose "emergency software recovery and initialization -> device initialization" in an attempt to revert it to stock rom and settings (is this method unroot the phone too?)
But after this long downloading finished , the phone didn't boot , I only see the samsung galagy s6 edge logo stuck!!!!
So , I decided to root the phone again , following the guide here (link-->), zidroid.com/how-to-install-twrp-root-galaxy-s6-edge-on-android-5-1-1/
(in short words , I installed the twrp recovery with odin and I flashed 2 zip files required, from an usb-otg-flash drive, via the twrp recovery install button) and then the phone booted normaly , but the problem with the signal and wrong IMEI was still there!
I feel that I am on dead end , I don't know what to do , I am thinking about sending it to the location I bought it but I am afraid that the warranty is lost.
Please help me restore my phone back to normal
After repeating the whole procedure several times , now my phone does not recognize SIM card at all , as if it was never inserted , wtf?

So you mean that there isn't any way of backing up the IMEI number first before rooting or changing a rom/kernel/recovery to the phone in order not allowing this IMEI bricking happen again by means of restoring from its backup?
I googled a lot and some people suggest that they can backup EFS in some way. What is EFS exactly and how it is related to IMEI?
Also wouldn't be a good idea to find a way to backup my entire OS/firmware (not just IMEI/EFS) before doing anything , in case to save money and avoid the same bricking?
And yes , I have sent the phone to samsung service , it will cost me around 320 euros , because they discovered I changed kernel/rooted the device , and they will change motherboard.
I cannot help the phone without being rooted , I love rooting but I cannot understand why suddenly IMEI got bricked.....does it worth to take risk and root my phone again? But I want IMEI or entire OS backups first before doing that and I don't know how to achieve this without rooting first...
Please help me if you could.
You can backup your full os using twrp recovery
Also your IMEI
In SAMSUNG devices imei number stored in efs partition that's why people asking take efs backup before flashing any Rom

Me too! I have the exact same IEMI number! Mine stopped working after about a month. I tried to return to seller no response. I tried to send phone back they would not accept phone, so it is on it's way back to me. Once I get it back I will try what you did.
I have taken it to factory settings 3 times no luck. I will try your process once I get me phone back.
Thanks!

I did contact one of those fellows a reputable one that can change your IEMI. Well once he heard that crazy IEMI number, he said because it was changed once before to something like he doubted he could change it again and save my phone. To try he charges 100 US plus I have shipping there and back. Yikes.
So any advice you can give me I would truly appreciate.
Thanks!

:good::good::good::good::good::good::good::good:
Mine went down recently with the exact same IMEI and no SN. TWRP was failing to restore the efs partition damaging the files in the process. Long story short, I had to manually extract the efs files, copy them across and fiddle about with permissions but I'm working again.
That nugget rings true - always backup the efs before changing anything.
But for that reputable fellow to say that the IMEI had been changed before because of what it had become, and insinuating that the imei couldn't be changed more than once was complete twaddle. I wouldn't trust him near any of my phones.
On a lighter note I'm sure there's got to be a member on here would sort it for beer tokens
Happened to me, I thought it was faulty ROM and all but then I realized it was simply apn setting. Resetting it to default did the trick. It can be found in Settings > Mobile networks > Access Point Names

Since this thread is quite old and people keep answering , I want to end it like this:
Back then I didn't avoid to pay about 300 euros to replace its motherboard to a samsung shop. But I learned lately that the issue was due to an app called "USB OTG Helper" (https://play.google.com/store/apps/details?id=net.shajul.usbotg&hl=en) which allows you to insert NTFS USB flash drives to your OTG phone but also enables a system partition , including EMS files to be visible.
And you can guess what happened next , I deleted this system partition which this app made it visible and yes , my IMEI was gone!!! After some months , I repeated the same delete thing , but previously I had backed up via TWRP the EFS and MODEM partitions. My phone lost IMEI again , as expected , but after restoring EFS and MODEM , the IMEI was back!!
To sum up , never delete files or partitions that look like "system" like bluetooth and imei folders when you are root AND always have a backup of all your rom via twrp or something else before changing/deleting/flashing anything related to your system.
