I seem to be screwed, my IMEI is gone and now the phone won't connect to any networks and is perpetually searching. I have no backup, is there someplace I can get a dev or dummy IMEI or put it in manually from the sticker on my phone? I need to hook it up to a network, and I think my EFS has been cleared...
I should note that the EFS folder is still on my phone, however the IMEI and Baseband are all blank in the system. Can I repair them somehow?
try http://forum.xda-developers.com/showthread.php?t=1264021
I was looking into that, but I can't seem to understand what he means by "Original Shipping EFS". Is that the one generated by Flashing stock 2.1 for T-Mobile? (JFD)
Have you ever changed or touched you efs folder? If not, than your good.

I forgot to update this post, but I kinda solved my own problem. Only caveat is that I edited my EFS too much and now it's lost (on generic IMEI now). The problem was that I actually forgot to set the modem in properly after opening and closing the phone the first time (was checking for a fix after bricking it). I opened it up and firmly set the modem finally getting me a recognizable baseband. I thought of the solution because someone said that it might be a defective modem, which prompted me to check to make sure I put in back correctly after opening it. 2 days of flashing was solved with a simple screwdriver

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.

If your EFS is not total screwed and your nv_data backup is valid its possible GSII_Repair from market will work for you ...

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
Z3x-box sa
msung - 169USD
Z3x-box LG - 169USD
Z3x-box 2in1 (sam+lg) - 299USD

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 phone's IMEI is stuck at the generic IMEI of 00499010640000, which appears doesn't work for neither my nor my wife's carriers. The EFS folder is apparently botched, because I tried following these instructions - http://forum.xda-developers.com/showthread.php?t=1264021 and nothing changed. There was no .nv_data file, only a .nv_data.bak, which I tried using to no avail.
I saw this post for the SGS3 - http://forum.xda-developers.com/showthread.php?t=1802024
Might that work with my phone? I want to try it, but I don't want to risk making the problem worse.
Also, my phone never asked me for the SIM PIN. Is that normal?
Hi all,
hope someone can help me. Since this night I am no longer able to connect to my mobile provider. I tested the sim in a different phone and the sim works fine.
When I go to settings, and search for the providers, I get all german providers but when I try to connect, it says it is not possible.
Is there anything I can try? Or could it be that something in my device is broken?
I have JellyBam CM10 4.12 running, but it seems to be not Rom-related.
Any help is appreciated.
Thanks!
Check your IMEI in settings/about phone/status. If it begins with '0044' (do not post your actual IMEI or any portion thereof here !), there's your problem. If that's the case, restore your EFS backup (there are heaps of threads about same on here).
Also, there's always the possibility the phone has been IMEI blocked (assuming your IMEI is correct/OK). If your IMEI is correct/OK, call your carrier & confirm your IMEI is/isn't blocked.
If neither of those things are the issue, I'd do a clean install of stock in the first instance & see if the problem persists. If it does, it may well be a hardware issue. If going back to stock does fix the problem, it's obviously a rom issue; maybe try a completely clean install of the rom you were using & see how that goes.

I tried everything except calling the provider.
My IMEI and Baseband is still visible and ok.
If I search for networks, it finds the networks, but says "Unable to connect".
This happens also with stock ICS firmware as well as with the custom ROM.
Does it mean, that my hardware is broken?
Not necessarily. But call your carrier & ask if the phone is IMEI blocked. It could also be a case of something not setup correctly at their end so far as your account with them is concerned.
That's what's you need to do next.

Ok i called and they tell me that they dont block IMEIs...
Tried another sim and this SIM doesnt even ask me for PIN entry??
Whats wrong`????
Well i'm quite disappointed now, I tried flashing various roms (custom and stock, ICS, 2.36) but still no luck.
I also noted now, that I have unknown baseband and no IMEI since yesterday.
I had a backup of EFS folder, but restoring it didnt change anything. Using EFSBackupPro...
Dont know what to do else...pleaasseee help
tgat diesnt sound good
Try restoring stock via odin

Try restoring your efs folder manually , with a root file explorer, if you have your efs folder backed up on your external SD card copy it to the root directory of your phone
i have restored the EFS folder from my girlfriends phone (just to test, because i have only an img of my backup)
No chance, still no Baseband/IMEI...
Seems to be a hardware issue? Or should I try to get professional help (JTAG?)
Should not be using another phone EFS on your phone. Data are different in them.
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 have an S2 GT-i9100 that someone gave me after they deleted the EFS folder from without taking a backup.
None of these fixes seem to work for me. I have IMEI unknown, IMEI SV unknown, Baseband is unknown, Network is unknown and the service menu displays no options. LOL!
Where the signal bars should be is a circle with a diagonal line through it.
I have rooted it, flashed several stock firmwares with Odin with no change.
I have an EFS backup from an old S2 (same model) that was water damaged beyond repair and thrown away. Is it possible to put that IMEI on this phone? I have tried copying it and going through this process detailed here and it completes fine but doesn't make a sausage of difference, even after reboot.
Any ideas or is it shagged?
I thought if the EFS folder was deleted the IMEI reverted to the Samsung default IMEI? When I dial the #06 all it says is "IMEI" in large letters.
Oh deary deary....
