Lost IMEI

Hi,
My IMEI is 004999010640000.
I understood from reading on this forum that it is not a valid one.
However, my phone works.
I did back efs folder but I might had backed it up after too ma y past flashes.
1. How can I know if IMEI is fine?
2. Can IMEI or eds folder be restored from carrier/other if my backup is obsolete?
3. Can I find it in an old nandroid backup? How?

If it starts 004999xxx then its been corrupted but you can always flash a stock samsung rom to get it back. Check this thread

10x,
If it is corrupted, how can flashing a stock rom restore it?
I am on ICS. Should i simply flash a stock rom using cwm recovery?
I'd hate flashing back and forth, is there any alternative solution?
If my phone works, why do I need the imei for?
Regards,
Trumpy

Unless you have a backup, nothing, just have to workaround the new imei and lost warranty.
How did you corrupt it?

Try HC's Ktool from Play Store. It has got the ability to backup and restore Efs.img and .tar. May be will benefit you.

Corruptions already occurred so your original imei has been lost, there's no way to get it back.
Can I ask how you corrupted it?

System Information dodgy.

Hello
I wanted to restore my note and looked around for an approprate restore file. I checked the PDA and other system things (See SS) . I couldnt see a file that matched all 3 settings. I bought my phone unlocked from China but the PDA tells me its from Germany. I dont want to mess it up because of a recent network lock after updating.
Any ideas? Thanks

There are no "automatic" backup files you could restore - you can only restores something if you or the previous owner made backups (with CWM).
So please explain what you mean with "restore"?

Thanks for replying. I have just flashed the Gingerbread firmware but it still asks for a code. It's very possible that I didn't do it right, could you elaborate? :good:

Is it the same problem, as in all the other threads you created the last days and hours? Just wondering,
why there is/was always a new one from you here to see and read....

Flash back to stock, should solve your problem

[Ques] Lose the IMEI after up CM 10.2.1

I'm having trouble after flash cm 10.2.1 rom from stock KK4. Now,my IMEI is: 004999010640000. Starup phone the CM is warning Lose IMEI faild. Please help for me restore my original IMEI

Use one of these Odin or Heimdall One Clicks to get back to Stock KK4. That has proven to restore the imei for several. Then once u r back and have the # restored, back it up in a few places, just in case u run into this problem again.

KK4 is stock GB, make a backup before you flash it using Titanium Backup.
Flashing KK4 should restore your IMEI. Once on it, make a backup (copy) of your efs folder before going back to CM. That way, if it happens again, you'll be able to restore it.

After going back to cm just copy efs folder again. need for set permission? Sorry for my English is bad

Once you are on Stock KK4, only then make a backup of the good efs folder. And after flashin cm or whatever rom, if you loose your imei, then you can restore the good backup from kk4.
There are some threads with tutorials somewhere in this forum and also apps on the Play Store that can be used as well.

There're a few as Slim rom after flash done no networks,no baseband, IMEI. Is the error due to EFS folder? and the problem is the same as mentioned above.

Yes. That is correct.

My phone have lost its IMEI since I bought it from my friend. I have bear the invalid IMEI notification for so long. Roll back to KK4 or even follow the hex editor topic doesn't work. Do you guys have any suggestion?

Stolen phone?
If both those options don't restore it, I'm not sure you can without a jtag.

He bought it brand new, and he did flash roms without backing up the /efs folder. I have the box with IMEI on it .
Is a jtag a tool that they use for hacking xbox 360?

Jtag is used to push ROMs/bootloaders into devices but I'm not even sure that would fix your problem if flashing stock KK4 doesn't fix it.
