Hello! I was having issues with my SGII since I lost my IMEI and I struggled to recover it You can check my story here.
Now I have mi IMEI but my phone is network locked. I tried to unlock it with Galaxy S Unlock but it didn't work.
Tried with GalaxSIM and after reboot it says is unlocked BUT my IMEI is lost and obviously my phone doesn't recognizes my SIM card.
I'm on Android 4.1.2
Build Number:JZ054K.I9100XWLSE
Kernel:3.0.31-Siyah-s2-v6.0b4
Baseband: I9100XXLS8
If my EFS folder is corrupted shouldn't I lost my IMEI?
Why I lose my IMEI after attempting to network unlock my phone?
Here are some images.
First everything is normal, I have my IMEI and stuff...
Unblock successful!!!
But after reboot, my IMEI is lost
And so my signal...
Thank you!

I don't have warranty anymore.
I'm currently traveling ( in other continent for 3 months ).
I don't have my ticket purchase with me.
To trigger this IMEI problem I have to attempt to unlock the phone... so I need to root, reset the binary counter, and then re-flash the original firm, after that binary counter won't be zero.

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.

Hi guys,
I've messed up and need help. Here goes...
I had a locked phone on the 3 network , a S3 I9300; and I wanted to unlock it. Simple I thought to myself.....anyways, I downloaded the voodoo unlocker after rooting successfully with Odin. Nothing happened it wouldn't read my T-Mobile sim card and I can't remember what I did exactly but I did press some buttons on that app in attempt to unlock the sim. I then realised that it was not compatible with the S3 and then I proceeded to use the GalaxSim app. I had to download busybox for that, after doing that I attempted to unlock it. Yipeee! Phone unlocked and everything green.....but not. I still couldn't register on any network(using manual method as well). I had even cleaned my SIM card(but not tried another sim card). I then unrooted the phone with stock rom and unrooted again to use GalaxSim......and pressed backup accidentally! That I means I am now with an unlocked efs folder as my default efs, I didn't check the IMEI number to see if it changed, but how I return it all to normal? Has my IMEI number changed or would it not show IMEI if I overwrote the EFS folder?
I need help, I'm confused.
What phone you post I9100 ?????
No or broken EFS then just restore your backed up EFS .
jje
sorry i9300.
No, the EFS I had was overwritten with the newer version when I reinstalled the app. Now I have only one EFS and that's the one currently installed(which says the phone is unlocked). The phone is not registering on any network. Is this a baseband issue or a unlock issue? The app is showing unlocked, it shows all the networks, but some are written as"forbidden networks" and I can't connect to any.
By the looks of it, the simlock will never return.

You cannot update an EFS with a newer version you can only restore your original backed up EFS .
Does the IMEI match that under the battery if not its a service centre repair .
jje
Oh and the platform is jellybean.
The imei is the same, but it is still "sim unlock". How can i redo the process?
your phone should be fine you restore your original imei or just copied your origanal imei again probaly for the best as you know you have a back up of it now
chances are your phones unlocked now and probaly just need to register the sim card with T-mobile to activate it
should always place the back up of your efs somewhere else aswell incase things do go wrong mem cards can corrupt
Both sims that i've used are contract. I can't register any. They all say disconnected on status settings.

Hi!!:
After reading and reading and trying every method i found on the internet, i still have not succeded with my problem which is this:
I tryed to flash an stock 4.3 to my free s3 movistar chile, but when it rebooted and after i wrote the pin code, it asks me for an unblock sim code
It presented signal but uknown network. I got back to 4.1.2 thinking that it should repair this, but no, it was worst, i got imei null,
After searching and searchingI found a cwm 3 files patch on the internet: one for cleaning kernel, other one to install kernel and the other one to install modem, and with it i got my imei back, (this is when i made efs backup, i know i sould have done long before ) but also the wknown network problem, with the phone asking me for this unblock sim code again.
I used galaxysim unlock to try to repair this, but it showed me that the phone is totally unlocked i think i remember it also showed me the state of csc and it appeared blocked, so i think this is where the problem lies, but i couldnt find any info about this.
when i go to state of the phone i see this
network: uknown
kind of network: umts
service state: out of service
mobile network state: disconnected
imei:3537.... thats ok, fits with the one on the back of the phone
device state: modified
(sorry if my einglish is not very accurate)
So resuming: my imei number is ok, wifi works ok, but even though the phone shows signal, it presents uknown network, and i cant do or receive calls.
i would be very thankful if any of you could help me
Your phone was unlocked using a crack that only worked on 4.1, by updating to 4.3 you've corrupted the efs folder.
You now need to buy an unlocking code and pay for a repair, make sure it works on 4.3 before you accept the phone back.

Thanks a lot for answering!. So, if the phone was cracked in 4.1.1, is there any chance to downgrade to that version, use the corrupt efs backup that i have, just in case i lose the imei, and try to unlock?, or would be too risky?
Not without a backup of the efs before you upgrade, no.
Hi everyone,
I come to you as I am a noob as far as twinkering with my gt i9300 goes and I think I messed it up big time.
Here is what I did :
I had android 4.2.1 on my gt i9300, the stock rom from sfr (french career).
I network unlocked it using my career official unlock code, which worked great. It recognized my japanese career sim very well (i am in japan now).
Then I got greedy and wanted to update my android version so I downloaded a 4.4 android rom from I don't remember well, and a cwm manager.
The network unlock worked fine at first but after a restart it did not work anymore. It asked me for a network unlock pin.
I thought it was asking for a sim pin at first, which my sim did not have as I hadn't set one. I got mad trying sim pin code and gave up. Had I given it the network unlock code instead of possible sim pin code it might have worked but I will never know.
Then I tried to solve the problem installing android 5.1 cyanogen version but I had the same problem except this time I understood it was asking for the network unlock code. The problem is that when I fed it to him, it did not work, the request was unsuccessful.
So I looked for a solution on internet and found all kind of things:
I read about restoring the efs partition, but i do not have any back up.
I read about installing a stock rom version, change the csc and retry the official network unlock code, but it does not work, whether I restore through Kies (which gives me a vodafone version) or manually (with an sfr version, french vodafone it seems).
I read about installing Galaxy simunlock app after rooting the phone and installing userbox, but it tells me that my locking system is not handled as it is too new.
I upgraded, downgraded, rooted in every possible way but nothing works.
I am running out of solution and I therefore turn to you for help, hoping you will be more creative than me.
I have the official network unlock code, the phone, no back up of any kind and really little hope.
Thank you in advance for any help you could give me !
Have a nice day !
Sadly you didn't make a backup of efs. That should be first thing before playing with customs.
Oh well, I suppose your efs may be screwed up due to entering couple times bad network unlock key.
I suggest go to next corner GSM shop and pay 2400JPY for efs fixing and perm sim unlock. But before that, check your IMEI and serial number are correct. Thay can fix all of this in one step.
You need to do this via box, you can't reprogram that or fix yourself because you did everything that may help and you still have a problem. You can't use any software on efs v2. It will not work.

Thank you for your quick answer !
I will follow your advice and go to a "professional".
However I don't understand how they are able to do what I can't, do they have special softwares or anything ?
I would like to know because I do have the official unlock code.
Also, I would still like to upgrade to android 5.1 cyanogen version, do you think it will be possible after such a modification ?
I should not encounter any risk if I backup the efs beforehand right ?
Thank you again
Service will connect your phone to, so called, box, ie Z3X Box. This is some kind of pc-phone bridge hardware which can alow to decrypt and encrypt efs files, fix IMEI, serial number, flash firmware, IMEI certificate, remove network locks, sim locks etc.
Of course you can backup your efs now but it is corrupted and useful. Backup this partition after repair. Than you will be able to flash anything you want. Even CM12.1,no problem.

Ok I understand better now.
Thank you very much for your answers, they have been really helpful !
Do not let them plug your phone to the box if you want to install 4.4 or 5.0 because if you give them they will replace your imei number with a clon imei number and you will stuck with max 4.3 and you need to install a patched modem and kernel every time you format your phone... tell them to try to fix without replacing your imei number first. Replacing the imei number should be the last thing to do...
Why do you think they will clone his phone's IMEI? It's even illegal.
If someone doesn't know how to use box than he should not work in GSM service.
You can rewrite original IMEI and serial number without cloning anything.
An probably IMEI is fine, it's network lock problem.

Most repair shops dont care its legal or not. Also most costumers dont know this kind of things and as long as phone is working its okay for them. Mine is just a warning to make him look like he knows this things so repairman doesnt do something with no going back...
Hi,
I got this phone from a friend and I don't know the history of it but is unable to detect any SIM card and the Baseband and IMEI appear as Unknown.
Do you have any idea on how to fix it?. Thanks in advance.
i had the same problem on 850FQ i bought few days earlier.
I digged deeper into the Issue and found out when someone wants to unlock their phone it can be done by 2 ways ONE: with an unlock code which people can buy from many online sites TWO: Using some hardware device i dont know its name. The repair guy told me sometimes a phones IMEI is also changed during the unlocking process and if the process is buggy then it may also damage IMEI AND BASEBAND.
Unknown imei/baseband can also be caused by a damaged "modem chip" or it can be caused by corrupt "EFS AND MODEM" folder while flashing custom roms. But since there is no ROOT and No firmwares available for the "A" model i guess your corrupt baseband is either due to "buggy unlocking" or it is a hardware malfunction. People who have the same problem in F or other models can try restoring factory firmwares with odin (from sammobile) but the folks with "A" Model are out of luck. i sold my phone as a demo unit cus i wasn't able to recover its baseband and imei.
Try a factory reset without simcard inserted, see if the imei comes back. if not you may sell it as a demo unit or keep the device for camera and music needs
