[Q] Analyse EFS backup

In my haste to try out the MI6 4.3 leak, I've forgotten to take a copy of my EFS backup from internal memory.
I've had a trawl around on my computer but I can only find an EFS backup from 28th of Jun, problem is I can't remember which ROM this EFS was attributed to. I'm not liking the battery drain on MI6 and I'm a bit hesitant to downgrade knowing I don't have my last EFS backup
Is there any way I can tell from the tar.gz the specifics of what ROM version I was likely using at the time?
Many thanks

No problem. Take efs backup from your mi6 rom.
Even downgrading from mi6 will not create efs problem. So no problem in downgrading.

That's good news
I suppose I'd not thought of the fact I could always just revert back to the MI6 leak if I took an EFS backup right now too!

E975: Backuping original LG's Software before going CM?

Hello there,
I googled a lot, I searched a lot here, but I did not find what I searched for.
I am thinking about testing the new Version of Cyanogenmod, the problem is that I in fact never did anything like this.
I want to set back the device to manufactures setting and then backup the original LG Software, so that I can go back to the standard before selling, or if CM isnt quite mine.
Anyone tips or links how to manage that?
Thank a lot before, sorry if this was asked before (I'm pretty shure), I couldn't find.

After rooting and unlocking,make sure you place the efs backup somewhere safe. You can also make a nandroid backup and restore it if you don't like cm. or you can use kdz updater to flash stock firmware.
I'm sure you looked all the places,except the FAQ

Okay, this sounds good to me.
Does any of the 3 Methods give me the same way of a full backup from the original software, or is there something else that has to be done?
I searched for the Faqs, but I couldn't find any?
Thanks a lot!

No, these are different things. EFS backup is to save your butt in case something happens with your IMEI. This is one of the most important things, don't overlook it! Nandroid backup is a "snapshot" of your existing ROM, including all your installed apps and their settings. This is the easiest way to get back to your previous ROM after experimenting with others. And KDZ is not a backup - it's a factory image that will return your phone to the exact same state as it was when brand new.

Look in @kimitza signature. It's his baby. :good:

the nandroid backup is like a restore image for windows. you will have all apps/settings from that time saved. here is a scenario:
1. On clean stock rom,root and unlock(unlock will also flash cwm recovery). Place FREEGEE folder somewhere safe.
2. Enter recovery mode and make a backup.
3. Flash any other rom ...and if you don't like it, restore the backup you made earlier.
4. Restore EFS with freegee.
5. Use Unroot from supersu.
6. Backup all your files(photo and other media to pc) then do a hard reset.
7. You will have a clean stock/official rom,like it came from factory.
All of this can be simplified by backing up your files and use kdz updater,followed by a hard reset. .It takes less time and it's safer.

I rooted it, but I dont have an hint of an idea how to do these efs backup?

what is to do with that zip? I'm from germany and I have no clue what run in recovery mode should tell me. On the Phone or on the PC?
If unzipped, what is there to do?
As I want to use the cm installer with 10.2 stable, I just want to backup everything important..

Sorry, wrong link, i meant this of course, its allready rooted

Sorry for posting again, but honestly, I'm not allowed to post in the efs thread, so I cant do anything right now.
Im still waiting to flash it.
Anyone should do efs backup, so basicly people should be able to tell me how to do that or?
Please anyone!

When you unlock the bootloader with freegee, it automagically makes a backup of the EFS,amongst other things(like bootloader state,imei,partitions etc). It's enough to place that FREEGEE folder somewhere safe. If you ever run into troubles(like no IMEI shown or you just want to go back to stock without using KDZ updater),just restore with freegee. It will relock you bootloader and restore EFS(with imei).

[Q] About EFS Backup

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.

[Q] LG G3 - Chip Card Changed as well as IMEI - Restore old backup?

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.

[Help] Nandroid Backup

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
