Hello
I have a Samsung Galaxy S2 with NFC (I9100P)
I backed up the full efs folder and attempted to unlock it using galaxy s unlock, but any attempt to do so makes the device lose the IMEI, althought it gets unlocked properly
I tried to delete the md5 fils for them to get generated again with no luck, I also set permissions and group ownership to the files
If I restore my old backup and establish the file permissions and group manually the device gets the IMEI back but becomes locked again
What can I do?
Thank you.

Just pay your carrier, better than losing IMEI
Don't unlock it with that app, get galaxysim unlock from spocky thread.

Hi, my Imei is corrupted, I flashed a custom rom, and I lost my efs/imei, now my IMEI is 0049..and can't do anything.
My best friend has got the same mobile (Galaxy i9300 s3), and he gave to me his efs folder and a back up, I tried to fix my S3 with it, and it doesn't work, when I reboot the nv_data.bin and md5 are generated by the SO, and they are not the same as I copied from my friend.
I have tried to recover it by all ways, s2 guides, recover your imei in 9 steps..but it does not work.
I also tried stock rom, and it is impossible I cannot get a "normal" imei, always 0049..
Any ideas?I need the phone as soon as possible, that is why I don't want to send it to SAT, here in Spain are 15/20 days for repairing T.T
I hope you can help me, Thanks!
PD: If you are here to say I stolen the phone, please DON'T post anything, because I really need it and I payed for it as you DID! :good:

What rom did you try to flash? I've flashed many many rooms and never had an issue like this.

Do not flash another phone's EFS, it's duplicating IMEI, is illegal and is not allowed on XDA. Even the discussion of it.
If you didn't have a EFS backup for your phone and tried some guides already, there's not much you can do. Send it back to samsung?
Hello,
i have a problem with my I9100G. It has the known IMEI 004999010640000. I want to repair the IMEI back to the original one.
Who can help me with that via teamviewer. The phone also always ask for a network unlock code when the pin of the simcard is entered.
The phone is/was a free one which acceped all cards. But now after the crash it do not accept any card without asking for a network unlock code.
If someone can help me it would be great.
I can also make a payment via paypal if someone help me with success.

First of all, never ever give an IMEI over the Internet, especially your true one. It is enough to mention that your IMEI has been modified. IMEIs can be stolen and in some countries there is a blacklist of them and you risk getting fined or, in some instances, prison.
Now, what ROM are you on? Usually IMEI corruption takes place when you flash custom ROMs. What you should try is flash a stock ROM on your phone. I know my brother has had the issue on his I9000 and he managed to bring back the IMEI by flashing a stock ROM.
If you have a backup of your /efs folder you should restore that. If not, for future reference, you should use Root Explorer or any other file system explorer to backup your folder and have it ready in case **** happens.
Some Kernels, including Siyah Kernel back the folder automatically.

Hi,
I used Android 4.1.2 and CM10.1 - on Samsung Galaxy S II model I9100.
During a phone conversation it was hanged up, and the phone could not connect to the network anymore.
I got an error when tried to manually search for network operator, which lead me, after a research in the net, to find out that the IMEI of the phone is empty. I see also that the Baseband version is 'unknown'.
I have a backup of the efs folder and tried to restore it by manual overwrite it - with no success.
I also followed the guide to recover manually the IMEI from here: http://forum.xda-developers.com/showthread.php?t=1264021 with no success.
I tried to get back to a backup of the original ROM I used before (this time using ODIN), and now I get NULL/NULL in the IMEI and I still get Baseband 'unknown'.
Also re-installing the radio did not help. now when looking for network operator the error is different - now it is telling me that there is no SIM card.
the NULl/NULL IMEI and Baseband version is 'unknown' are still here and I still can't connect to the network.
last input: after 2 days of phone being unused - it suddenly got back to work, the original IMEI got back in, and it connected to the network. this happened without me doing anything, and it held for half a day, then the phone got back to the non-functioning mode as described above, again in the middle of a phone conversation.
I am out of new ideas, all related threads in here did not help.
Can anybody help ?
Does anybody know the reason for this issue?
Can tell what is the thing that is probably corrupted, and in case that the problem is with the files in efs folder - why doesn't a restore of the efs folder (including chown for nv_data.bin to user radio) did not help?
Thanks !

EFS is corrupt.This was a bomb waiting to explode.I suggest you to go back to stock JB 4.1.2 ROM (see my signature),and flash Apolo kernel.Go to recovery and restore backup.Do not overwrite it manually.Do it in Recovery.

Hi GamingDj,
First thanks for the reply.
I want to add more inputs and few questions:
Right now, after more then another day that the phone was not functioning - it got back to operate again, and again, without me doing anything that will cause that to happen.
During the last time that it happened, this held the pone in a working state for about half a day until it hanged up on me during a phone conversation I had - and the phone stopped working again, so I am not very optimistic about the phone getting back to work for good right now....
I have a bit more data that I forgot to mention before:
1. About a day before this problem happened, Avast anti virus offered me to update the Avast Anti theft software, this required root access and I don't know if it has something with the reported problem or not.
2. The efs folder was "handled" by GalaxSim Unlock, after the phone got locked due to official upgrade to JB. Originaly this was an O2 locked phone, then it was unlocked with a code, but due to the upgrade to JB it got SIM locked again and the codes did not work anymore, which caused me to use the GalaxSim Unlock application - that indeed unlocked my phone. I know that the GalaxSim Unlock application changed some data in the nv_data.bin in efs folder, but after it unlocked my phone it was working fine for about a month or more, so I can't tell that this is the cause for the suspected corruption in the efs folder.
I have both backup of the efs folder before and after the unlock operation by GalaxSim unlock application.
Can you explain in more details:
1. Why you suggest to flush Apolo kernel? is it in order to have the phone rooted? can you give a link for this kernel?
2. Restore backup from where? should I have a backup file that you point to? not sure what backups I have that may have data that I don't already use.
3. Does the new data help with debugging this issue?
Thanks again.

Hi,
Just want to update that its been about a week that the phone works without me doing anything, therefore not proceeding with the recovery process you suggested.
I will update if the problem will be back.
Thanks.
Hi,
Im new to all of this, so I have a few questions:
- I have successfully updated my i9100m from GB to ICS(using the stickied guide)... without losing my unlock. Will I lose my unlock if I flash from ICS to JB?
The reason I'm asking is because I've read that there are some cases where ppl have lost their unlock.
Interesting thing though,
- galaxsim(xda version and marketplace version) unlock is unable to read my .nv data and it's status is undefined.
- chainfire galaxy 2 unlock can't find an unlock code.
- helroz galaxy_s unlock gives me gibberish for the code.
the imei from *#06# is the same as the one on the phone behind the battery.
this phone was given to me because it had the eternal flight mode problem, which I fixed by repairing it with helroz gsII_repair.
Any feedback is appreciated!
What do you mean "lose my unlock"? Is your phone carrier branded or an international model? Because the international models are not SIM/carrier locked.
BE CAREFUL WITH SIM UNLOCK. First backup your IEMI because SIM unlocking can corrupt it.
I have a bell branded i9100m.
currently it is unlocked but I'm scared that it will relock.
I have backed up the efs file, but this was already after the file was corrupted to give me the eternal flight mode.

Doesn't sound too good, my friend. Corrupted efs is worse than SIM lock. Are you able to make calls? Send sms?

I can make calls, sms, data works fine... that's why it's weird. *#06# gives me a IMEI, when before it didnt.
Is there any tool or method that I can make sure that my .nv data can be restored for sure, so that I can sim unlock in the case that upgrading to stocj JB might relock my sim unlock?
You can use HC-ktool to backup your IEMI. It's in the play store.
Need help I lost my phone IMEI Galaxy s6 edge SM-925W8, is there a method of recovery. I board not backup.
I tried to flash the original system and without success, I tried with mem Smart Switch but it does not work
One or the first things you're supposed to do when you get a device rooted it backup the efs partition. It can easily get corrupted. If you don't have a backup of the efs, all you can do now is send the phone to Samsung and have them restore it themselves. Happened to me with the s3 back in the day so now I just backup my efs everytime I root
Thank's, now the phone working, I find same codes, I can make call end network work work but still no IMEI.
