[! DISCONTINUED !] [TUTORIAL][LOCKED][UNLOCKED][ANY G4] DLM Backup
- Thread starter steadfasterX

Restore a previously taken backup or partitions of an already extracted KDZ
There are 2 methods available - choose the one matching your needs:
Unfortunately this may not work on every firmware so you may try different firmwares then and you will receive the same error regarding communication port closing but in general it should work this way.
A) Restore a previously taken DLM Backup / Restore partitions from an extracted KDZ
To restore single partitions use the following
sudo python2 auth.py
sudo python2 partitions.py --restore /path/to/dumpfile partitionname
e.g.
sudo python2 auth.py
sudo python2 partitions.py --restore /tmp/misc misc (would restore the misc partition)
To restore ALL partitions in a folder
For this the best is to use the new LGUP NG kdzmanager which is explained in the next topic.
Install LGUP NG but skip the steps to extract a KDZ if you don't need it.
Then:
bash kdzmanager.sh --test --flash /path/to/imagefiles
(/path/to/imagefiles must contain your previously taken DLM backup files or an extracted KDZ)
This will just test flashing and not actually flash.
If that looks fine do it again but without --test parameter:
bash kdzmanager.sh --flash /path/to/imagefiles
B) Flash a KDZ / LGUP NG (next generation) by sfX
Forget LGUP to flash a KDZ from now on!
Just use my KDZManager
Features:
Keep in mind that this is an early release and there are NO CHECKS like ARB or even if the device model matches with the KDZ but THIS WILL ALL COME (even with an option to override and flash regardless)
Roadmap:
Instructions:
Type in the new opened terminal:
Download my brand new kdzmanager tool in FWUL: (right click and save as)
Open another terminal (black little icon in the panel)

Forget LGUP to flash a KDZ from now on!
Just use my KDZManager
Features:
- No worries anymore about those crappy DLL issues
- Extract a KDZ
- Test flashing partitions (dry run without actually flashing anything)
- Flash partitions from a KDZ
- when flashing avoid erasing/wiping userdata (keep your data between KDZ flashes)
Hint: not wiping userdata can occur in a bootloop when its not compatible with the ROM! So use that option with care. - will work on any Linux (but FWUL is the only supported)
Keep in mind that this is an early release and there are NO CHECKS like ARB or even if the device model matches with the KDZ but THIS WILL ALL COME (even with an option to override and flash regardless)
Roadmap:
- GUI
- Check for matching device model
- Check for ARB
Instructions:
- Boot FWUL (or your Linux but keep in mind that only FWUL is supported), choose language & login
- Download the KDZ file you want to flash (we need to know the path later e.g. /home/android/Downloads/)
- Open the folder LG
- Connect device in download mode to the PC
- Double click "LG laf NG" icon
Type in the new opened terminal:
- sudo python2 auth.py
[*]sudo python2 partitions.py --list
If this lists your partitions then we can proceed with flashing.
Download my brand new kdzmanager tool in FWUL: (right click and save as)
- When you are not using the persistent mode of FWUL: plug in a big USB stick (e.g. 32 GB or more) into FWUL and extract the attached file there
- When you are using the persistent mode of FWUL: just extract it in your download folder
- You need to know the full path so best is copying the path from the file manager (e.g. /home/android/Downloads/ ) or leave the file manager open there
Open another terminal (black little icon in the panel)
- cd and directly behind this paste the path you copied (e.g. cd /home/android/Downloads/ )
- press ENTER
- bash kdzmanager.sh -x FILLINFULLPATH-TO-DOWNLOADED-KDZ
(e.g. bash kdzmanager.sh -x /home/android/Downloads/h811blablubb.kdz) - WARNING-1: Keep in mind that atm kdzmanager is not able to proof if you choose a compatible KDZ file for your device!
Check your device model and the KDZ twice!
WARNING-2: Keep in mind that atm kdzmanager is not able to proof your current ARB version so flashing an smaller ARB then your current one will BRICK your device.
Check ARB first: CLICK
If you understood the above 2 warnings proceed like this:
bash kdzmanager.sh --test --flash extracteddz/
(just like this as "extracteddz" is the path generated by the kdzmanager)
This will just test flashing and not actually flash. Let me know the results of this (copy & paste output) - if you can't wait the next step would be actually flashing ofc:
WARNING: by default the kdzmanager will not overwrite userdata (which would be like a factory reset) and I would recommend to leave it out always and better choose the LG factory reset menu (after flashing completed) if required. If you still want to flash it use --with-userdata as a parameter (can take a loooong time then btw).
bash kdzmanager.sh --flash extracteddz/ - last step ( will be included in the next release): wipe your userdata:
sudo partitions.py --wipe userdata
Or just use the factory reset hardware key combo to do the same.
If you skip this step you may encounter a bootloop. If that happens you can at any time use the hardware key combo to boot into factory reset to fix that.

FAQ
1. Q: You get the error message: "Expected arrow in ls output" when executing lglaf
A: update to the latest version of lglaf (thx to @tulen_kobi for this patch!). For updating lglaf on FWUL check Q4.
If the error still persists your download mode version is not supported by lglaf. Its very likely that your carrier has a very strict policy activated in download mode. The only chance is to try other download mode version meaning to flash different KDZ files (on locked devices) or just the laf.img in fastboot (on unlocked devices).
On Nougat and when unlocked it is enough to just flash the laf.img of MM and you can use lglaf again.
2. Q: You get not an error but messages or files containing just "Hello, I am LAF. Nice to meet you."
A: your download mode version is not supported by lglaf. Its very likely that your carrier has a very strict policy activated in download mode.

On Nougat and when unlocked it is enough to just flash the laf.img of MM and you can use lglaf again.
3. Q: All seems fine but at the end of a command you see: "comm.call(close_cmd) [....someotherstuff...] Command failed with error code 0x8000010a"
A: This is known and not a serious issue.Once I have the time I will fix it but in the meanwhile pls ignore..
This has been fixed. please update your LGlaf like described in the next FAQ
4. Q: I want to update lglaf on FWUL v2 or higher
ok here is the correct way to achieve this on FWUL v2:
cd ~programs/lglafng/
git pull
git checkout g4
then you're up2date and can try again while in this folder!

I'm so happy that you were able to finally get this working. It's dumping my system partition right now. I'll report back when it's done.
Also. You should note that the sudo password is "linux" and to view progress on the dump, you should specify that the command should be opened in a new terminal window.
Over all. Awesome tutorial!
EDIT: Was able to retrieve 7gb of lost pictures thanks to this method! Thank you!

well it sounds like u have not much RAM attached to your VM then. 4 GB are recommended.
The dump error can be ignored as long as auth.py has worked before and everything gets dumped..

what if .. i dont have USB.? am planning of backing up my IMEI. as i been reading this on the new N roms..
what can i do.?
If you have an unlocked device you have luck and you could use dd commands in TWRP. I know that yours is unlocked so you could use dd on every partition available on your device.
Tbh the most important seems to be persistent, fsg, misc but until I know for sure I would just backup EVERY partition. It's only needed once in the phones life usually so it doesn't hurt..
I need to have my device repaired before I can test it further so this can take a while.. Until then the backup of every partition is the best choice.
if the device is locked and on LL then TWRP in FIsH plus the mentioned dd commands can be used as well. I would still recommend the download mode backup though..
if the device is locked and on MM or N (haven't tested N in download mode though) then USB plus download mode is the only choice.

Similar question. What's the quick and dirty way to backup these partitions from terminal app / busybox?
Dd if=??? Etc
not sure if different between models but mines h815 international running 'stock' nougat

OMG so basically if this works in locked N, can I flash the korean v30 kdz and then restore a backup the modem.img from v29a made for my H815 with this method?
The possibilities are amazing
I will add it in the TWRP thread ASAPSimilar question. What's the quick and dirty way to backup these partitions from terminal app / busybox?

Technically this method can provide that (as said I can't test N atm though so I don't know if this works in general for N but if LG hasn't changed anything.. )
but:
keep in mind that cross flashing partitions can result in a soft brick on locked devices!! I don't know how N behaves here tbh so it may just work or it may soft brick in the specific case of modem.
So it would be nice to have someone trying to use the auth command on a N bootloader stack. This will not harm anything but then we know for sure if this is usable for N or not
