Hi every1
I see a lot of ppl on the QA complain about losing their imei number due to bad flashing and other circumstances.
I dont wanna risk screwing up my phone flashing roms so I was wondering what is the least hassle/best way to backup the efs folder?
Can u just use root explorer and copy the whole folder to extsdcard and then put the backup on the pc for future use
OR
What are the best apps for making backups and are they 100% guaranteed to make a working backup and restore with no problems?
Back up as many ways as you can, copy it to pc, use k-pack tool from the market, and copy those from your sd to pc as well, can't be too safe!
Just to update u guys pro efs will backup your efs folder to your pc no problem I recommend using this before flashing too much

Not 100% on the whole contents of the efs folder but its very important as it contains your imei number which is like a mac address its unique to your phone to identify it on a network always worth keeping a backup incase sonething happens to it

EFS is one of the partitions in the root directory which stores some of the most important data such as IMEI number, phone number etc, things which are unique to your device and will make your phone a paperweight (no network connection) if you mess with it..
Take a backup of this folder in case you face any problems..

I'm one of those "people".
so the answer is no. =)
you have to back up the un-corrupted EFS folder that have your IMEI in it.
there are many software and apps that claim to back up those file
you can just search "how to back up efs folder" there should be plenty of solutions and guild.

Dear Noob..you cannot change the IMEI number yourself..you need to have a backup of your EFS folder for that..if you backed it up use the Ktools app to restore the nav_data.bin file...
Otherwise Service Center..
I hope it helped..
P.S. Post questions in the Q&A section..it is there for a reason..
I also flashed omega v14 and ended up the same as you

Looks like you are in deep trouble.
Considering you are asking this question in general section, I'll take the liberty of assuming that you did not backup your efs folder.
May be someone else can pitch in here to help you. Meanwhile you can confirm if you have the backup of efs folder or not?

Think Omega automatically backs up efs?

Here is a guide to repair your IMEI from the SGS2 Forum! It should be the same! I solved my IMEI problem with this Guide on my SGS1.
http://forum.xda-developers.com/showthread.php?t=1264021
[GUIDE] Recover your IMEI in 9 steps.
It is very important that you back up your efs before flashing any ROM, and before you folow this guide BACKUP the faulty efs folder because it contains the old backup of the file nv_data.bin. It beginns with a dot like .nv_data or similar (because I haven't a SGS3, but the structure of the efs folder should be similar).
Please be carefully and think twice what you are doing!!!

You can't, efs folder is where your imei and other device specific information.
You can only use yours, changing imei is illegal.

If you are asking this question then download the toolkit to back up your efs folder.
Also considering that you have international version of this phone so possibly you are not from USA. It's currently legal to change imei number in USA but double check in your country to make sure. General rule of thumb - only USA has this legal.

I really doubt you can just download an efs, that seems illegal.
You may just have to bring it to a Samsung repair centre to get your imei back.
You can't just download a new one.

I copied my efs backup onto a friend's phone which had a corrupt efs to see if it'd work. Didn't help. So I they think what you are trying to do is useless.

Your EFS is specific to YOUR device and if you have lost YOUR efs, then you're screwed.

Your only option to repair imei without having to go to Samsung is to have an efs backup, you don't have one.
Contact them and ask, I doubt they will charge you 202 euro to get your imei back, I don't think they need to replace the motherboard.

I don't think so either since your IMEI, serial number and everything is on the phone sticker and/or box of the phone...
i already call samsung and they dont understand what im talking about :silly:

One for Samsung to repair your phone there are one a need to know the correct IMEI either on the box or under the battery .
Two they may well also ask for proof of sale to you .
Take the phone with the above to a Samsung service centre .

Backing up someone elses folder will only give you their IMEI. by doing so you will void the imei as it cant be on 2 devices. Not to mention no one is gonna give you access to their IMEI number. My suggestion would be to start over from scratch.
Try GSII Repair by helroz. If that doesn't work you will need a professional restore. Mobiletechvideos can do it for a small fee.

No idea.. what would be best would be remembering how you took them....or perhaps the dev thread for the 2nd app has more info - did you read it /ask in the thread.
If you can't restore the backup, you can try and restore to stock otherwise send for repair
