After updating H815T-HKG to v10c through LG Bridge
It can't use this command to extract the system.img
Code:
dd if=/dev/block/mmcblk0 bs=8192 skip=55296 count=529920 of=/data/media/0/system.img
After a while, the folder has nothing changed,
so is it the number of block is changed?
BTW, can't download the kdz through LG kdz checking website
so can't extract the kdz to fix it.
I have the kdz copied from app data temp folder when using LG Bridge to upgrade the phone. You can check if it is still there. It is around 1.7G.
I found the link:

If you want to check your "dd" parameters, you have to extract the GPT from your phone.
Then you can calculate the values yourself and check if they have changed.
I wrote an guide how you can do this:

Did it work?

I've waited for almost 2 years to have R530C debrick image, no one have that file. I almost give up, and then my stupid idea came up... ( You'll need linux terminal, and basic linux command knowledge )
1.) Download odin package for your device ( make sure it's the same version with your latest firmware before got bricked )
2.) Extract the .tar.md5 file ( WinRar / 7zip will give error message, just ignore it )
3.) Grab debrick image for your device, or at least the same variant ( R530C / U / M ) firmware version doesn't matter.
4.) Clone the debrick image to your microSD card.
5.) Now back to extracted folder of your firmware, copy these files :
sbl1.mbn
sbl2.mbn
sbl3.mbn
aboot.mbn
rpm.mbn
tz.mbn
to your working directory
6.) List your debrick microSD partition using parted ( mine was /dev/sdb, make sure you have the right partition before doing these commands )
I forgot the command, but it's something like
Code:
parted /dev/sdb
Code:
(parted) print
7.) Now you can see the partition list (sbl1,sbl2,etc)
8.) And then do this :
sudo dd if=sbl1.mbn of=/dev/sdbX
sudo dd if=sbl2.mbn of=/dev/sdbX
sudo dd if=sbl3.mbn of=/dev/sdbX
sudo dd if=aboot.mbn of=/dev/sdbX
sudo dd if=rpm.mbn of=/dev/sdbX
sudo dd if=tz.mbn of=/dev/sdbX
9.) After finishing all the command, remove your microSD from card reader, cross finger.. and Good Luck.
Sorry for my "not-so-easy" tutorial, I wish I could explain it a little easier to understand.. but my english sucks
I am about to flash the rooted system image for the LG G4, using the "Low Effort" root method at http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
Before I do that, I would like to back up my system (and perhaps my user) partitions. Since I don't have a custom recovery, I am not sure how to do that.
Can someone help me?
Thanks!

To backup the system partition on the VZ LG G4 VS986, After you've got the drivers loaded on your PC and and have installed the G4root send commands and have adb loaded, but before you use dd to push the pre-rooted image, run the command:
dd if=/dev/block/mmcblk0 bs=8192 skip=65536 count=548352 of=/data/media/0/system.img
This is dump your original system partition to the system.img file on the internal SD card.
and what would be the command to backup system 815?
Hi1 my device running 5.1 V10C (H815). I want to flash prerooted v10c or D. Please give a guide to how to flash. Thanks
Do you have an image for it?
*edit*
Here's a pre-rooted H815 EUR 10D image I made:
https://www.androidfilehost.com/?fid=24052804347837030
With this image, SuperSu will ask to update. I'd recommend doing it.

Thank you. I am new on Lg. How can i flash this image safely?
Use thete steps: http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
With this command (H815 specific):
Code:
dd if=/data/media/0/rootedsystem.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
If you want to back up your current system partition first, use this command before running the above one:
Code:
dd if=/dev/block/mmcblk0 bs=8192 seek=55296 count=529920 of=/data/media/0/system.img
And if things go wrong, you can restore your backup with this:
Code:
dd if=/data/media/0/system.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0

If you have an unrooted system.img I could make it a rooted one.
Or follow the root injection method here to do it yourself (requires a linux OS):

If you don't back up your system partition, it means more effort required to re-flash a stock KDZ if it breaks. Or if you needed to revert to the previous version (v10c) or something.
You could also keep the rootedsystem.img I made on there and use that as a backup, assuming it works on your device.
Hi guys,
There is a working solution to Unbrick LG G4 phones , the solution actually works For the H811:
H811 Unbrick
This solution relies on mmcblk0 dump file. There are people with other variants that can't find the dump files, so if someone happens to have a Rooted G4 with TWRP installed please help to save some G4
you can dump the first 512MB of the mmcblk0 with this command from either terminal emulator or adb shell :
dd if=/dev/block/mmcblk0 of=/sdcard/dump/dump.img bs=512MB count=1
after that please upload the dump.img file to a file sharing platform like dropbox , mediafire, mega.co.nz , google drive
and share the link and the variant here
Please help others
all the variants are welcome to join the party
Code:
# dd if=/dev/block/mmcblk0 of=/sdcard/dump.img bs=512MB count=1
dd: block size `512MB': illegal number
I think I need to specify the block size in bytes. What number shall I use?
__
sol
it would be great if there was a way to get a dump from kdz/tot cause i dont think F500L has bootloader unlock method yet,may as well stuck forever

I'm working on a fix to unbrick the US991 variant.
Can anyone please get a systemimage dump and share? Or provide a link?
All you have to do is run the cmd below and upload the system.img to Androidfilehost, Dropbox, Google Drive, Mediafire, etc...
Here is the command:
dd if=/dev/block/mmcblk0 bs=8192 skip=65536 count=548352 of=/data/media/0/system.img
can you please describe the process !!!
