Do you know if there are providers that block your
IMEI? I do not have any problems with my carrier now but I will soon go to the states, and I don't know wether my phone will get blocked there.

I don't know any providers. but as a guess, I think some providers MAY block an irregular IMEI because of their security policy. but it's just a guess.

To make a conclusion:
... You didn't backup your EFS folder.
... Your IMEI changed because of ROM flashings.
... You want to recover your IMEI.
I don't understand how you were able to apply the steps you describe to your case if you didn't have a backup of your original efs folder...

My SGS 4G IMEI is corrupted showing some random symbols. Now I have taken backup of my EFS folder. EFS>root>afs>setings has .nv_state and nv_data.bin.
In IMEI folder there are only two files bt.txt and mps_code.dat.
Can it be repaired back to original IMEI? I don't have back up of my original EFS folder.

I didn't had a backup of my original EFS folder BEFORE IMEI CHANGE.

after my IMEI has been changed to the fake one, then I backed up my EFS folder and do the steps in the first post.

the Content of your IMEI folder is correct, we don't have any business with the IMEI folder's content.

but look at your EFS folder contents, find the file named " .nv_data " (no post-fix), then do the steps in the first post.

but NOTE: my SGS 2 is a GSM model, not the 4G model, so I cannot guarantee that this method works with your phone too as it did for me.

thank you

Hi...

I don't understand very well what you mean by

Quote:
NOTE THAT AT LEAST YOU MUST HAVE THE SHIPPED ORIGINAL EFS FOLDER ON YOUR PHONE

Do you mean that we should have the efs folder with the sud-folder and files structure as it was when the IMEI was not corrupted???

I.E.

/efs (dir)
nv_data.bin (file)
.imei (hidden file)
.nv_data.bak (hidden file)
.nv_data.bak.md5 (hidden file)
nv_data.bin.md5 (file)
nv_state (file)

/.android (hidden folder)

/imei (folder)
bt.txt (file)
mps_code.dat (file)
nvmac.info (file)


Another issue i'm facing is the fact that I can't do a chown radio:radio because i get the error that user/group radio does not exist...

And would this work for SGS I?

Like others I am confused.

I flashed a ROM night before last.
I ended up with a phone that wouldn't work and the fake IMEI number.
By some chance I was able to get my phone working again with HC-kTool by restoring a efs.tar file -- I have a number of efsxxxx.tar.gz files in a folder called EFS_BACKUP on my sdcard (I don't how it got there but there are various dates of these files).

Now my phone works with data on the ATT network but my IMEI number is still the fake one.

SOOOO -- if I DON"T have an original backup of my EFS folder (or at least one I'm sure of) HOW do I restore my origianl IMEI ???

Thanks to all the Developers!
