Hi Friends,
i have a noob question about the EFS backup. So far i understand is the backup on 4.1.2 not compatible with 4.3 (new bootloader) b'coz it has a different folder path. What me makes scare is, i've read some posts from some users that they have no imei after official uptade with odin.
Why do i ask? I want to backup efs and flash the pre-rooted 4.3 rom without new bootloader b'coz i feel safer and the efs backup will work. But in my mind is to test the new 4.3 with new bootloader and knox (i know its not easy to get 4.1.2 back)
Is it really risky o are there some newbies wich makes mistakes? Can i paste the old backuped EFS folder in to the new path for correct imei?
I really searched on the forum also except XDA, but there are similar questions with different answers.
Thanks to all
I think that if you are worried about restoring, you should do a full nandroid backup to SD card from recovery. That way you don't need separate EFS backup as it is included in nandroid backup, so you can restore whole phone exactly as it was before.

1. Is EFS backup really included in CWMR or Philz Recovery?
2. Can i get back to 4.1.2 from 4.3 (new bootloader) only with an older NAND backup?

1. I don't think so. In Philz, efs backup option can be found in Custom Backup menu
Check this thread out for backing up EFS http://forum.xda-developers.com/showthread.php?t=2389426
2. I did restore my 4.1.2 nandroid backup after flashed DN3 rom. It worked. But do efs backup for just in case.

I wanted to get all of your opinion on backing up the IMEI.
My situation is, I had rooted last year with the s3 toolkit. 1st rom I flashed was paranoid android then now i'm always flashing Task's AOKP. I'm currently on an older release of his rom (5-21-13) and i've probably flashed it a dozen times without any problems.
My question is, should I continue flashing this rom even though I have not backed up my IMEI or EFS folder or should I flash back to stock right away then, backup IMEI/EFS and continue flashing task's rom? Are the chances high of losing IMEI even though i've flashed the same rom for at least a year now?
I have an AT&T SGH-I747 with baseband DLK3.
In addition, if I were to flash back to stock, can I just use this? http://forum.xda-developers.com/showthread.php?t=2161667
Unfortunately the download link is no longer there so would anyone have a copy?
Also, would this be the best / easiest way to backup the IMEI as of right now? http://forum.xda-developers.com/showthread.php?t=1804117
Thank you!:cyclops:

I don't know about backing up your IMEI but if you want to switch back to stock 4.1.1 I recommend using this instead: http://forum.xda-developers.com/showthread.php?t=2363882
It worked like a charm when I was on LK3
always have a backup... as for me i have a copy in my 2 emails, dropbox, work hdd and home hdd... fixing qualcomm imei its much easy and anyone could fix them, in exynos cpu the history its diferent...

Unfortunately EFSpro will only let me do the option under backup on EFS Professional to backup the tz, efs, modemst1, and modemst2. Qualcomm crashes due to me currently being on AOSP. Looks like you must be on stock in order to use that. Any tools that will work for other roms besides stock?

If I were to go back to stock it would simply be to backup the IMEI then flash back to AOSP right away. It looks like that restores stock everything (stock kernel, stock rom, and stock recovery)
I would like to keep my recovery but flash stock rom for AT&T S3 through TWRP so I can keep my recovery.
I backed up my imei because the more posts I read, the more it seemed like having a backup would be crucial if you wanted to restore and be successful.
Since that stock rom that I linked to was no longer active, I searched my old backups and found a stock CWM nandroid backup I made after I rooted. I was on TWRP so I flashed the recovery back to CWM via rom manager. Restore the stock nandroid I made then backed up my IMEI.
Switched back to TWRP and made a nandroid backup of the stock rom with twrp so I don't have to mess with recoveries in the future.
Flashed my 5-21 nandroid that was Task's AOSP then just updated to his latest 9-10 release.
All is great and I have a full NV backup.
Thank you all for the suggestions.

Could you walk me through on how to have a full NV backup? Also how would I restore it if I ever needed to? I wanna know just in case I ever lose my imei.

Download a terminal app(root required one) then type su enter reboot nvbackup.
To restore it's su reboot nvrestore.
!!!!!!DO NOT RESTORE BEFORE YOU BACKUP!!!! You will overwrite nv with empty data possibly losing imei forever.

Hello I going to return to stock rom but I have one question about Nandroid backup.
I have a backup from CWM Recovery and I now using TWRP recovery can I still restore the backup? if so where about do I copy the backup to on the sd card?
Thanks

you need to flash cwm recovery first and do a full wipe. I think the backup folder is clockworkmod/backup/"date". I find it easier to just wipe then do a backup, even though is nothing on your phone, and this will give you the file structure you need. then go to the "backup/date" folder and delete the contents and replace them with your saved backup and flash it. and dont forget to flash the boot.img from your backup too
Hello! I have successfully rooted my sm-p605 Note 10.1 with CF autoroot and also flashed TWRP. So far so good!
I´m looking forward to flashing Android Revolution HD on it but I have not yet been able to backup EFS.
I have tried to do it with EFS Professional 2.0. There is no actual filter for this device so I tried using the Galaxy Note 3 filter as i think they have equivalent hardware, that gives me the error that I cannot create tar archive. I also tried to choose "all partitions" but that gives me checksum error.
I am not really sure that I wan't to risk bricking my 750 € tablet by flashing a custom ROM before getting a proper EFS backup.
Are there by the way a risk of corrupting EFS in case I only restore the stock rom backup made in TWRP?
That would be my second option, to only make some root enabled customization and debloating in stock TW and not touch any custom roms and in case of messing up, restoring stock backup.
So, is there anyone that have been able to backup EFS on their sm-p605/Samsung galaxy note 10.1 2014 LTE Qualcomm?
I do apologize for my crappy English, I ain't a native speaker.
After some research I came across some comments on various websites mentioning that it is possible to restore EFS by flashing stock firmware.
Can someone please verify this? That even if I will not be able to backup EFS i still can restore it by flashing Samsung stock firmware?

Got no idea but you can use a file explorer to grab a copy of your EFS folder with a file explorer like ES and copy to your sd card then transfer to your PC...
Don't know how much of a help this will be but at least you have a copy if you think you can follow some of the recovery instructions and need the original files....
I flashed the same ROM and I remember during the installation it asked me if I want to backup the EFS. I pressed yes and it just did and install the ROM.
Any success on backup EFS folder? I've the same device and i'm planning to try custom rom too
So I flashed a very bad ZIP file that hard bricked my phone.
Now my phone has come from Repair Service and its motherboard (or so to speak Chip Card) has been changed. The phone's IMEI has also changed during the process. :silly:
I have a backup of a well working ROM that was made with phone before the chip card renewal. Can I safely restore the backup after I've rooted and installed TWRP to the repaired phone?
I assume the backup is very important (of the current Stock Rom) but can the backup be restored in a safe way?
Assuming they didn't hack together some other phone's motherboard into your phone (not likely at all), then yes you can restore the backup. Your IMEI doesn't matter. Anyone can restore a backup from the same kind of device.
You'll likely have to do any kind of backup first (modem is fine), then move your of backup into the folder it created.

Only if you don't restore EFS, misc and other phone-unique partitions. tz, rpm, data, system and cache are ok.

How did you make the backup? TWRP or Nandroid Backup

Not trying to be picky, but, a TWRP Backup is a NANDroid Backup. I think you may mean; How did you make the Backup? TWRP or CWM Recovery? TWRP and CWM have similar feature sets, and there’s little practical difference between them. They do have different user interfaces and are not compatible with one another. A Nandroid backup made on one cannot be restored using the other.
Backup restored - followup question.

I did the Nandroid backup with TWRP.
I did take the risky method and decided to Restore the backup "as is" (every partition of the made backup).
It definately took some time to boot and also on initial boot the cell phone signal from carrier wasn't being received until about a minute had gone. After that though everything has worked as it should 100%. :angel: I did have a lot of setup done in the backup and that was the main reason I wanted to get the phone state back to what it was (before sending the phone to service). On the side note I would have definately been very pissed off had I bricked the phone again when I restored the previous backup. :cyclops:
I did a backup of the stock firmware before restoring the previous backup (= old "chip card's backup" or better said the backup made with phone having different IMEI code) and now I'm wondering whether of not I should restore some specific partition of that stock backup with TWRP. I quess the old saying "if it ain't broken don't fix it" applies here. Would be interesting to know if someone has better knowledge concerning this.
I absolutely recommend the if it ain't broke, don't fix it angle. It's unlikely that your TWRP backup contained any partitions that weren't safe to restore on your new phone.

+1 :good:
I need someone who has done nandroid backup for GT-I9190 running on stock rom (4.4.2). One of my friends has not computer and he wants to flash stock rom via cwm. If someone has nandroid backup and upload for me, I will really appreciate that. Thank you
Nobody will post an nandroid backup because it contains all personal data, IMEI, contacts, messages and so on.
I remember that there is a EFS option in TWRP. If you don't check EFS option, it will not backup EFS.

Sorry I don't use TWRP and don't know too much about.
Good luck
