Hi,

After installing a custom ROM, the IMEI reported by Android is different from the one on the sticker under the battery.

I believe the IMEI is somewhere in the 'efs' folder, but where exactly? There are all sorts of files and folders in that folder.

There is even a folder called 'imei', but it contains just one file called 'mps-code.dat', and that is only three bytes long, which isn't enough to contain the 15-digit IMEI.

Can anyone help?

Thanks,
Steve

It's inside the efs folder in the root of your phone.

Backing it up eh?

No, my phone stopped working and I think it's because the IMEI has got corrupted when I was messing with various custom ROMs - it no longer matches the sticker. I want to figure out a way to fix it - I can't bear the thought that I've just bricked a fine phone that I paid good money for.

Where in the efs folder? There are loads of files and folders in there.

Thanks,
Steve

Wait wait,
You can't text or connect to the network?
Try flashing a official firmware and see if the IMEI matches...

It's not that simple to modify your IMEI n.o, special softwares are required to do this.... It's stored in .nv_data
Don't you have any efs backups?
IMEI getting corrupt is seen many times in s3 and note 2 devices....
And also, modifying your iMEi is illegal, but people out there use a software to do it.... May not be good to discuss this software here...

And one more thing, does your phone shows a generic IMEI number when you dial *#06* ?

Thanks for replying, eatsleep. That's right - the whole phone works fine. It will see all the mobile networks in my area, and will register itself on mine (O2-UK). The only thing that doesn't work is voice telephony, SMS, and mobile data.

Yeah, I've done that. No good, I'm afraid.

Here I must admit to being a bloody fool. I didn't know what I was doing and messed about stupidly in CWM, mounting and unmounting, deleting, reformatting, and so on. Basically I was trying to follow several guides at the same time, and made a total mess of it.

And no, I didn't know about backing up the efs before I started.

Not a generic one. It's really weird, because it's almost but not quite the same:

Sticker inside phone:
xxxxxx05861xxx3

*#06#:
xxxxxx05681xxx1

The ...86... has reversed to ...68... and the final 3 has become 1.

I'm an idiot and furious with myself.

Thanks again for any help you can give, though.

Steve

Wow! I've just seen how much it costs to buy that eight-tentacled device who's name shall not be mentioned.

$135 makes poor sense if it's only going to be used once. Perhaps the best idea is to check my local phone repairers until I find one who has the device?

Bumpety bump just this once:

Any chance of correcting the IMEI myself?

Thanks,
Steve

Hey babe..... please remove both of your IMEIs from here and never post them again in public. I'll post back in some time.... and your IMEI looks quite fine to me but still, lemme look for some time

And, your phone is not bricked, you've just got a bad IMEI

Thank you for replying! I've edited my post to remove the IMEI, as requested. Perhaps you could alter the one where you quote my message?

I realise everyone must say this, but I'm genuinely not trying to do anything questionable or immoral. I just want to restore the IMEI so it's the same as the one on the sticker.

Thanks,
Steve

Can't find some content for your device but please do one last precaution before following any more tutorials, backup your efs folder and place it in a safe place.......

If you don't find anything, I can provide you with some guides for s3 (my device ) but don't know if they'll work for you....
One advice, reset your phone and send it to any service center.... They may charge you if you are out of warranty.....

here is a random thread i found but I have a bad feeling about the person.... Carry on at your own risk but back up your current efs, it may be recoverable but can move to a unrecoverable state after some repair attempts so, we can have hope....
