helo,
i am using samsung galaxy s2 GT-i9100
i flashed cm9 before and then i flashed samsung europe stock.
and now i see, my imei number has been changed.
can anyone help me to revert or change imei again!
Problem i am facing:
1.) call , message not allowed. (Gprs is working fine)
when i call, it says error "Mobile network not available"
i think its becuase my imei is changed to some europe imei now.
i want to get my real imei back , to make calls etc.
so, can u suggest me things to do?
did you make any efs backup? if you did then just restore if not... then it will be really difficult... there is few threads about it around somewhere in this forum ( seen it few times ) use search and i wish you good luck
ps. next time install ktool from hellcat and backup efs

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?

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
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...

I appreciate any kind of advice.. I am a semi-noob...Now i am using my old SE Walkman W8 till this gets fixed...
Thank You
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 lost my efs backup thats y i am stuck up here... otherwise i would have restored it long time ago...
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
The IMEI number on my S3 is completely gone, i installed a custom ROM and after it booted up i wasnt getting any signal. i didnt a little reasearch and found out the imei number file has been deleted and is wasnt backed up. does anyone know how to recover the IMEI number? I reverted back to the stock rom and unrooted my device but the IMEI thats underneath the battery doesnt match with the one it shows when i dial *#06#, when i dial that the IMEI is 004999010640000/01 and when it was rooted and on a stock rom it showed "null". if anyone knows how to fix this can you please give a detailed walkthrough on what to do.
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
