How did it get corrupted?
Have you tried flashing a stock rom?

Questions go in the QA section, not general

I know as you need one phone service box ( spt box, octabus box, z3x box etc ) for re build nv_data.

I'm one of those "people".

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.

oh, well I used this app called nitrality to back it up, but not sure where it backed in up too
and I tired using rom manager to help but I cant find the galaxy s3 as an option on phone models
See if Mskip will add efs backup/restore to the toolkit i know the Nexus version of the toolkit has it
http://forum.xda-developers.com/showthread.php?t=1746665

where ?

where can i download efs form
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.

i know im scewed i have to options wait for imei repair or send to samsung for changing motherboard
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.
Sent from my GT-I9300 using xda premium
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.

[Q] EFS Partition Modified

Sp, here I am. I updated to MG5 and my modem got modified. No other modem works and I know it why. The question is, Can I restore my efs if I use a backup of my friend's efs? Will that cause any damage to my phone?
From what I learned about efs from another topic pertaining to lg optimus g ( I'm sure its the same for all devices ). The efs stores your imei number and such. But other users may correct me if I'm wrong. So using your friends efs wouldn't help at all. I'm a noob to all of this still.

efs does store our imei details. Pre MG4 modems had a different efs format. The format was kinda updated by samsung on MG4 and MG5 roms. I have no signals on any 4.2.2 roms either. However, an older backup may restore the previous format, no matter if the backup was made on someone else's device. Right?
I honestly couldn't tell you bub. I don't want to say go ahead and do it and then something else messes up.. I would wait for a reply from a much more knowledgeable person. Sorry that I couldn't help.

Your friends efs back up has your friends' imei , which if you use would be modifying your imei , which is kinda unnesessary. If you have your own efs back up just restore it.
sent from the state where Marijuana is NOT illegal !
Just go back to an EMGx modem.
you need an efs backup before installed mg4 or mg5 rom. for now no way to go back old efs format without a backup. and another efs file doesnt work with your phone. efs file contains encrypted imei and something phone information for detecting craking
