[Q] how can I back up efs? - Galaxy S 4 Q&A, Help & Troubleshooting

I've heard there might be some problem with efs upgrading to 4.3 . now I'm going to upgrade to 4.3 and I want to know how can I back up my efs.

Wouldnt a manual copy paste backup of the efs folder with root explorer do the job?

check this link for a how to backup your efs
http://www.droidviews.com/how-to-ba...imei-on-samsung-galaxy-devices-did-you-do-it/
also if you have philz recovery you can use it to make a backup . A sound advice is that you cannot have too many backups for this folder .

thanks @difyel and @kuljit55 for your answers.
I had s2 and I knew everything about it. but I was away from mobile phones stuff for a while. I think I need time to remember them all!
so, a simple copy and pase would do the job!

He means efs folder. If you flashed the initial cm7 there should be a folder called backup on your SD card. Inside all your IMEI information should be there. Search the forums for more information on this problem. There are SEVERAL other users that have experienced this problem as well as resolved it.

If you look at the very bottom of the first post it's the instructions on how are you going to restore it.
If I were you Id make sure you lost your efs data.
Did you check the /efs folder to see if its empty?
Okay i tried the busybox command and it doesnot work.. i also tried thre others
Is your phone unlocked?
I have some files here which you would just put your efs folder then it will restore it for you. But i really can't remember the exact process.
I tried doing that with linda file manager but it said read only... kinda sucks cuz that would have been easy... anyways.. i have all those files on the root of my sd... i also tried modifying the code by adding /sdacard/ before /nv_data.bin to select were the file is (root of sdcard)
Don't edit anything on your original efs folder.
Ok, i have the files uploaded. But before anything please don't blame me in case whatever happens to your phone. I used this in the past because my IMEI also got screwed. It's your decision whether you're going to use it or not.
http://dl.dropbox.com/u/23360211/insert_efs_save.zip
Here's how i remember it.
1. So you there's an efs folder there and you replace that efs folder with your original efs folder. Again, your going to replaced it not put inside it.
2. You have to be rooted of course, and connect your phone while on USB debug.
3. There's a file called in insert efs folder.bat you click it and it's going to show you what to do.
4. Pray that it would work.
Again, please don't blame me. It's your phone so don't do this if you're not comfortable doing it. But hey, you've got nothing to lose.
Wait what rom are you using right now?
Im using cm7 n im gonna try that now
Try to go back to stock first if you're going to try it, back up your efs folder to your computer.
Wait stock as in jfd? And i already have my efs backed up, when i flashed the initial cm7 it backed it up... but if i go stock i can get everything back to normal by just simply doing an odin right? Cuz when i do go back to stock, i plan to just go use simply honey hkney instead...

Odin plus JFD + the right pit file also check the re-partition. Then root and restore your efs.

TWRP Nandroid?

On TWRP Nandroid Backup there are 7 options that can be backed up: Boot,System,Data,Cache,Recovery,EFS and Preload. The 1st 3 are always checked but I was wondering which of the other 4 options do most people check when doing a Nandriod?
Thanks
Boot,System,Data,
that is ALL
You might want to backup efs once just in case you lose it down the road. But I've never had to use it

That is a given, but is it not needed every backup. backup efs for sure once, and put it in a safe place.
Thanks for input guys. So it it just makes the Nandroid a bigger file with all checked but not really necessary.

Thanks button would be nice
I made two Nandroids after rooting; 1st being Boot+System+Data and 2nd just EFS alone

no, youre not restoring it. might as well take it out of your head. if it was a photo, or a small file, id say you had a chance. not a file as large as a nandroid, sorry.

(Help) Lost imei after flashing stock root d801

I have a t-mobile g2 d801, I rooted then backed up my efs with freegee then installed nrg ROM. I decided to see if the restore efs would work so I used freegee to restore it. Then I flashed the latest stock rooted ROM and now I'm getting a reboot about 30 seconds after the Os boots a date my imei is gone. Please help

I can't give you specific help to fix this, but, I can advise that you make an extra backup of your EFS. Copy it off of your phone if possible. If not, just copy it to a different partition on your phone, so you have more than 1 copy in more than 1 place.
If you attempt to return to stock with T-Mobile flashing tool all the data on your phone will be erased. So moving a copy of the EFS backup off your phone is the first thing you want to do. If you can use ADB with the phone you can get a copy of it off your phone.
After that, I'd wait for someone with specific knowledge of this problem to assist you in fixing it. Assuming the backup of your EFS file is good, you will be able to fix your phone.

I'm in the same boat. I have my efs1 and efs2 img files, but no idea what to do with them. Any help is sincerely appreciated.

EDIT: Autoprime listed this method for restoring efs
autoprime said:
If flashable zip wasn't created or to manually restore efs img files run the following commands using adb shell while in recovery:
dd if=/sdcard/EFS_Backup/efs1.img of=/dev/block/platform/msm_sdcc.1/by-name/modemst1
dd if=/sdcard/EFS_Backup/efs2.img of=/dev/block/platform/msm_sdcc.1/by-name/modemst2

I tried that, but still have "0" as my imei. Perhaps this method could work for someone else in this thread?
freegee doesnt work, then you probably lost root
also try when wifi on
contact freegee maker with log. you may have found a bug.
try rooting again

Shouldn't be a problem as long as you can still make phone calls and use mobile data. I believe Omega gives you the option to backup EFS partition again. I do it every time I flash a rom so I have the backup.
Make sure you copy it from internal storage to external storage or the PC before doing a wipe as you may loose your EFS backup otherwise...
