[GUIDE] Backup/Restore LG Optimus G EFS Partitions

LG Optimus G EFS Backup/Restore
Every rooted Optimus G user should backup their EFS partitions! Included in this thread is a flashable EFS backup script and terminal/adb commands if you want to do it manually. The script automates the entire backup of all 3 EFS partitions and then packs the files into a flashable zip for easy restoring later. Place this zip somewhere safe other than your sdcard!
Thanks goes to toastcfh for the script help and everyone in #lg-optimus-g that helped out with EFS testing.
Original Optimus G EFS Thread(ZERO EFS) - HERE
Background
You never know when your NV/EFS may stop working correctly. Restoring your WORKING EFS may save the day. A few users in the #lg-optimus-g IRC channel have run into issues and found their phone unusable, myself included. Our issues could have been fixed if an EFS backup was made while the phone was still in working order.
m9kefs1 seems to be radio related
m9kefs2 contains your unique phone identifiers: IMEI, phone number, etc
m9kefs3 seems to be blank 00s​
Backing up EFS
It's easiest to run the Optimus_G_Create_Flashable_EFS.zip attached to this thread. Run in recovery. Optimus_G_Create_Flashable_EFS.zip creates a flashable zip backup of your EFS in /sdcard/EFS_Backup/(instead of just a .tar). Confirmed working on TWRP 2.3.2.3/2.4.1.0 and CWM 6.0.2.7. Confirmed NOT working on CWM 6.0.1.5. Please check to make sure the backup zip worked and actually made a .zip file in /sdcard/EFS_Backup. Any issues please list what recovery and version you are using and please post the recovery.log.
If you don't like convenience this can also be done manually with adb or terminal with the commands below.. root required.
Code:
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs1 of=/sdcard/m9kefs1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs2 of=/sdcard/m9kefs2.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs3 of=/sdcard/m9kefs3.img
Restoring EFS
To restore your original EFS just boot into recovery and flash the efsbackupflash.zip in your /sdcard/EFS_Backup folder.
If you don't like convenience this can also be done manually with adb or terminal with the commands below. Adjust the "dd if=/sdcard/" command depending on where your backup EFS .img files are located.
Code:
su
dd if=/sdcard/m9kefs1.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs1
dd if=/sdcard/m9kefs2.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs2
dd if=/sdcard/m9kefs3.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs3

[I]v1 EFS backup zip[/I]:
backed up m9kefs1.img and m9kefs2.img then .tar'd them.
[I]v2 EFS backup zip[/I]:
backed up EFS then creates a flashable .zip containing the EFS partitions.
[I]v3 EFS backup zip[/I]:
zip script is now "safer" and should work on all Optimus G variants.
[I]v4 EFS backup zip[/I]:
backup zip now backs up m9kefs3. this is for "completeness" only.
I believe m9kefs3 contains no worthwhile data.

Thanks for posting this, it is very much needed and all OG users must have their EFS partitions backed up. And i can confirm that m9kefs3 doesnt contains anything except zeroes, still its good to have it backed up

I'm on CWM 6.0.1.5, what is the newest CWM version that works the the Canadian LGOG variants that doesn't give sd-ext mount errors?
I tried 6.0.1.7 but got constant errors.

I also get sd-ext mount errors on my Sprint Optimus G(ls970). The errors don't seem to get in the way of anything.. seems it's just visually annoying. I'd love to see official TWRP versions for LGOG device.

Some information: flashable zip does work correctly on official at&t twrp 2.4.2.0 on my rogers e971. sdcard/EFS_Backup only the 3 .img files and no zip

Thanks for the update. Apparently the 7z binary Im using in the script is dynamic.. and won't work with everyones setup. All my tests were done using CFX 4.2.2... seems there's stuff in that rom not found in some other LGOG roms. You will just have to dd the partitions if you ever need to restore. I guess at this point.. consider a working flashable .zip a "bonus" :-/
Also... the newest FreeGee app in the Play store supports EFS backup.. also backs up 3 separate .img files. :good:
The official TWRP for the Sprint LGOG also has EFS backup support added into the normal backup section. I would *think* this would run on Canadian LGOG's... you guy's don't have external SD right?

We have external sd. There is no sd card slot on my Canadian Rogers E971 phone.

Just backed em up using the FreeGee app.. Aren't EFS flashed every time you flash a ROM?

Thanks for this great tutorial!
I've been having an issue with LTE on my Rogers LGOG. I've tried KDZ-ing back to stock, factory resets multiple times, many different ROMs, and I can't seem to get LTE any longer. It was working before the data partition got damaged though, causing me to need to factory reset for the first time a couple days ago. I believe after that this started to happed.
Just wondering if anyone has a stock clean Rogers EFS backup I could use, or modify and use, if possible. Or if there is something else I could try. I've tried various radios, wiping caches in between, ensured everything like APN and setting were correct, even got Rogers to re-push my account. My SIM is fine in my roommate's HTC One X for LTE right away, and his SIM card is NOT fine in my LGOG, no LTE.
Not sure if the EFS is the only thing left or not. Even after multiple factory resets and everything it seems like this is the only thing left that will solve the issue!
Thanks to all!

Just wanted to mention this has now been FIXED! Thanks to some hard work from autoprime, Paulicat and a little by me (lol) I'm fully back on LTE. Will have some documentation about this issue in the next little while as we confirm more information about the issue.

need help no 3G/LTE
I bought an F180L from Hong-Kong. It is a Korean version (U+) LG Optimus G. When I turned on the phone (before I put sim into) offered me to upgrade it. After upgrade there is no 3G/LTE. I have tried almost everything (rooted, unlocked bootloader, installed KDZ, intsalled stock and other ROMs) nothing worked.
I read about backup/restore efs, but I don't have efs backed up, so nothing to restore it. I tried to find old ROM (F180L 10q) to make a backup of efs, but I wasn't able to find any KDZ file to make 3G/LTE working.
I'm not a beginner rooting, unlocking phones but I need a tutorial how to make it working. Luckily I know my IMEI, Baseband, kernel, software version, but nothing else. Is it possible to fix this problem.

probably not.. but id need a partition list from the optimus pro first to correctly respond.
my efs backup script for the lg optimus g might work instead. btu again.. ill have to see your partition list first.
run the code below in adb shell. paste output in pastebin.. post link here.
ls -al /dev/block/platform/msm_sdcc.1/by-name/

ok going to be hard to say without actually seeing the actual partitions... because you have both m9kefs1/2/3 and modemst1/2 . your efs is either m9kefs1/2/3 or modemst1/2... the optimus g used m9kefs1/2/3... the g2/nexus 5 uses modemst1/2.
im going to guess and say lg og pro uses m9kefs1/2/3 tho(same as lgog)...
if not.. then the g2/nexus 5 efs backup would work - http://forum.xda-developers.com/showthread.php?t=2514095
if u wanna run both.. then send me the backup zips it creates.. i could look thru them and give you an exact answer on which one to keep. again.. im leaning towards your efs being in m9kefs1/2/3 tho.. which means this lgog backup method would work.

I have actually able to extract my efs modem file using a script which was made for LGOG i got back 3 files one is larger 65Meg file others are 3 mb each approx.
I think you are right that it uses m9kefs1/2/3 though I am not sure what it means but can you help me in one thing? I want to flash other stock rom than my own which has less carrier stuff (specially korean U+) and is in english entierly including the dialpad, sms limit and annoying call to korea or local call options!
but i have like tried telcel, claro, panama, hong kong and indian roms on my cell but after flashing the modem i can't seem to get it working. e.g. panama takes the modem i get the signal but when i tried dialing or pickup a call it crashes!
I am going back to korean f240L but i really like to leave it!
here is the link to download modem

Any user friend who has E970 and who is rooted, pls download below file and run in recovery to back up the phone's EFS parition, then pls mail me that backed up EFS parition file so that i can replace it to run my sim card:
http://dl.xda-developers.com/attach.../8/4/9/9/Optimus_G_Create_Flashable_EFSv4.zip

I want to know if anyone could share the content of this file. I tried looking at the fstab and translate it to the file but I haven't got it to work and the sgs4mini isn't supported by kitchen (but many people have made rom flashables for the mini, although I'm not sure if using the kitchen). Could anyone provide us one?

Which model? I9190, I9192 or I9195?

Sorry, I forgot to add that, it's I9190. Although having them all in one post would be really helpful to anyone needing one in the future for another version of the phone.

It worked thank you! Your script's content is very different from the other galaxy files included in the kitchen tho I would have never guessed!
I could flash the rom and it booted (although it took a long time even after the third boot up) and the wifi didn't work even though I have flashed the same (but stock) rom with Odin and everything works just fine since it's the one my phone came with originally. The thread main topic is solved tho, thanks!

[STOCK] H815 10A STOCK/ROOTED ROM [system + boot + modem + bootloader]

{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
These are for the H815 variant only. Files are from software version 10A.
Included below: a stock rom.. a stock rooted rom.. and flashable boot, modem and bootloader zips. ​
Requirements:
You must have TWRP 2.8.7+ installed to use these files. Thanks to Dees_Troy as always for that. And, of course, you must have your bootloader unlocked for TWRP to work. Please do not ask if "model x" is supported... did you unlock via LG's official unlock tool? Yes? then you can use it. No? then you can't.
Downloads:
ROMS:
Your options are 100% stock rom or 100% stock rom + root. No customizations here. Rom is odexed. Zip flashable in TWRP.
LG-H81510A-Flashable.System.Boot.zip
100% stock untouched system/rom and stock boot.img (kernel + dtb + ramdisk).
Not going to upload a rooted image this time... just a waste of space. Easier to just flash stock/untouched rom then flash the SuperSU zip from Chainfire... or just let TWRP root it (when you go to reset to system, if TWRP detects no root it will ask if you want TWRP to root you).
Latest SuperSu zip can always be downloaded here - download.chainfire.eu/supersu
Thanks as always to Chainfire for maintaining SuperSU!
Extras:
TWRP-Flashable stock extras. If you ever need to restore the modem, boot or bootloader.. these are the files that make it easy.
LG-H81510A-Flashable.Modem.zip
This is a flashable stock 10A modem.
LG-H81510A-Flashable.Boot.zip
This is a flashable stock 10A boot.img. Boot.img contains kernel + dtb + ramdisk.
LG-H81510A-Flashable.Bootloader.zip
This is a flashable stock 10A bootloader. It contains aboot, factory, hyp, laf, rpm, sbl1, sdi, sec and tz.
Also, all stock images are available from @wolfgart's CODEFIRE DIRECTORY

Second ROM is on the way..

So, with this ROM we can return the phone to locked/stock bootloader? What does the 10A stand for? Sorry I haven't ROM'ed in a few years (since a few HTC's ago), been just rooting for the last few years and using Nova Launcher. Is this still only for H815 EU's (which are able to have the BL unlocked via LG) or is this for all H815's?

thank you sir

TWRP-Link dont work on me.
But if it is the modified with simlink from @Wolfgart, than recovery works (backup/recovery), tested much times, all fine
http://techerrata.com/dees_troy/p1.img
Example: tried Xposed arm64 = bootloop! !!! dont test Xposed yet!!! all testers got bootloop
--> recovery and back in the world
most know, BUT FIRST after getting unlock and TWRP --> do a NANDROID!!! and TEST it!!!

Since most of us don't have root, me including(H815-L) i wonder if we somehow can install it via LG Flash tool, like a KDZ file?

i messed up..
its flashing of "LG-H81510A-Flashable.RootedSystem.Boot.zip" enough, or do i need to flash modem, bootloader too

if you just have all other partitions stock and cleaned you only have to flash "LG-H81510A-Flashable.RootedSystem.Boot.zip" (system and boot img included).

Could you list partition of H815 EU to me ? Maybe I will devs adb tools for LGG4 like LGG2.
ll /dev/block/platform/soc.0/by-name

Did you do this rom with a TWRP backup or do you have the official KDZ file? I formatted system partition, so no more recovery or OS and I can't us ADB

just done on the first day....

Make attention that on booted OS you can see platform name as : f9824900.sdhci
Accessing adb shell from TWRP Recovery you will have platform's name as : soc.0

How do I back up modem? F500L soft bricked. Help?

Ive soft bricked following
http://forum.xda-developers.com/showthread.php?t=3170550
original prewarning instructions for F500L flashing rooted system.img 10w over 10a.
Some have been able to successfully boot their devices using H815 10b kdz but loose or have faint signal strength.
So here's where I need help backing up my modem(s) before hand.
I've tried LG bridge to restore to stock as well as other LG support tools to.no avail.
Any help or suggestions would be great.
EDIT:Ended up flashing H810 10A KDZ, it booted but had the same problems others had with H815 10B, no signal. Flashing the modem.img from F500L backup did not flash back/restore. I ended up trying H811 KDZ and rendered my phone useless. After it completed flashing, it reset to dark screen. Lost download mode. It still has "QHSUSB__BULK", there seems to be a way to recover from here, there are instructions for the Nexus 6 and LG G3, but none for G4. I gave up and bought a replacement H811.

You are probably going to have to wait for a kdz. You might as well try and flash away. As long as you don't f-up download mode, you haven't much to lose.
You should be able to run the below using send_command.exe. This will back modem up to your internal storage. You can't use sdcard because it would have to be mounted.
Code:
dd if=/dev/block/platform/f9824900.sdhci/by-name/modem of=/data/media/0/modem.img
---------- Post added at 10:37 AM ---------- Previous post was at 10:21 AM ----------
To be safe, do your EFS partitions too:
Code:
dd if=/dev/block/platform/f9824900.sdhci/by-name/modemst1 of=/data/media/0/modemst1.img
Code:
dd if=/dev/block/platform/f9824900.sdhci/by-name/modemst2 of=/data/media/0/modemst2.img

I think there are 3 modem partitions, have to search. It was posted here somewhere.
Awesome ill try.
I have a backup of my original system.img as well but dont know if or how to get it back on to internal memory of the phone. Unfortunately did a hard rest to troubleshoot the bootloop.

Unfortunately there is no way to get it back on the phone's internal storage.
I have an idea though. Try backing up ALL your partitions. Then flash KDZ. Then copy old system.img you had backed up to internal storage. Reflash ALL your partitions in DL mode.

I have an idea though. Try backing up ALL your partitions. Then flash KDZ. Then copy old system.img you had backed up to internal storage. Reflash ALL your partitions in DL mode.

Yea ill do that. Will do some research on here to find that partition list. Then figure out how to back each up.
Once ive got that ill do the test with kdz.

I just included a few of them with commands in my previous post. You're model is different than mine, so not everything will be the same. But, you will have the same partitions, just slightly different placement. Here is a list of my partitions:

fyi, you probably don't have to include the spare partitions or userdata. @autoprime could probably tell us there are others that don't need to be included.

So let me clarify, by different placement, you mean altho I backup named recovery.img partition, it might actually not be recovery. But as long as I back up the parition regardless of what I name it, and recover it to same partition, it should be ok, correct?
Or are they same named partitions, except physically placed on device in different locations? But as long as I backup up name it should backup regardless of physical location and restore the same?

They are located on slightly different blocks of memory. The names are the same. If you back it up by name, it doesn't matter what you name the .img file. As long as you restore it to the proper location.
ie.
Code:
dd if=/dev/block/platform/f9824900.sdhci/by-name/recovery of=/data/media/0/recovery.img
could be run as
Code:
dd if=/dev/block/platform/f9824900.sdhci/by-name/recovery of=/data/media/0/blahblahblah.img
as long as you restore blahblahblah.img back to the recovery partition.

I was hoping this would return a KDZ

@tabp0le
Bad news, phone isn't doing anything when I type commands to back up, it just returns to #
EDIT: I checked /dev/block/platform/ nothing found. I ran dd if=/dev/block/mmcblk0 bs=8192 skip=65536 count=548352 of=/data/media/0/system.img" and it works.

Hmm. Try substituting the /dev/block/platform for the actual partition names... (make sure you have the right ones for your device) example below.
For my modem, I would try:
Code:
dd if=/dev/block/mmcblk0p1 of=/data/media/0/modem.img
I think you should only need your modems, system and boot partitions.

Tried that, returns to #, no modem.img in /data/media/0/

Need to figure out how to calculate bs, skip, count ect.. Of each partition. Not sure exact what we absolutely need. Assuming system, boot, modems at minimum.

Yeah, boot and modems is what we need. I don't know how to calculate those numbers. I can't seem to get a response from anyone either. Nothing on Google that I have found either!

How did you calculate? Need boot.img, modem st1 and st2 bs, skip,count to back up too.
We're so close..

Can someone here make a boot.img with a custom kernel that can function with cyanogenmod 12.1?
There are some people trying to port it to this device but we need someone to make that kernel.

crDROID and Resurrection Remix for the Micromax Canvas 5 both work for this device, tested myself.
Not sure if it's just me, or do SIM cards not register with these? If anyone could tell me, it'd be much appreciated.
