I have a question.
My phone (samsung galaxy s2 gt 9001) has a generic imei, it is completely diffrent than original number imei under battery.
Phone works fine and I can make calls.
I want to flash phone to android 4.0 but I do wonder if phone will return to original imei after flashing (and let me do only emergency calls - original imei is probably blacklisted) or phone will still keep generic imei and allow me to make all calls.
thank you for your help
Did you make an /efs-Backup?
Did this happen after flashing something or...more information please!
You should always back up your EFS folder, which stores your original IMEI. I hope you did, have a look here anyway: http://forum.xda-developers.com/showthread.php?t=1264021
Chris.
You say your IMEI is probably blacklisted .
Stolen phone ???
A factory reset or flash of new firmware is always the first step to try EFS recovery so yes their is a chance of correct IMEI .

flash clean,stock firmware...an always backup efs folder tht is in good state...

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...
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

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
2 weeks ago I flashed Ultima Rom onto my phone and It won't connect to my network so I restored my android backup with still no luck.I brought it to the shop where I bought the phone and they fixed it straight away for me.
Last not I flashed android 4.1.1 stock Rom through Odin and it said emergency calls only again so I rooted the phone once again to make sure my phone didn't lock to a certain network but everything is still unlocked. I tried to restore my refs backup but got stuck in a boot loop so I restored back to the android backup again.
I can't seem to figure out how to get my phone connected to the network. My imei is corrupted and it's the same as what it is on the box. I've searched the internet for a solution but have found nothing.
Does anybody know how to fix this??
Your help would be much appreciated.
Thanks
Usual suspects .
Not correct IMEI
EFS faulty
User does not have correct modem
User has not entered network settings / has wrong CSC for network/location .

Could you tell me how to go about trying to fix it.i have no idea what to do.
Is your IMEI the same as under the battery .
Have you restored your backed up EFS folder .
Have you the correct CSC for your network OR have you entered the network settings yourself .
Do you have a modem for your region .

One us a bigger text two read the multiple identical posts for a solution .
The basic answer is to restore your backed up EFS folder as that is the first step .
Second try factory reset or flash stock firmware .
Fails then its a service centre repair .
