In LG phones L7/5/3 to opted for DZ format, if we unpack one ROM KDZ we find a CAB, and if you unzipped the CAB seems the DZ.
DZ files are tablets that can be flashed directly, and as always, you can unpack to extract the ROM in BIN format.
NECESSARY TOOLS
Unpack KDZ = LGExtract.exe by navossoc.
Unpack CAB = any decompressor, on Windows, eg. WinRAR.
Unpack DZ = DZDecrypt.exe DZ_Creator.exe by copsfrance
And of course a ROM format KDZ or DZ.
PROCEDURE
The first thing to do is to unpack the KDZ, so copy the file LGExtract.exe on the route where we have the ROM format KDZ and from the console (which previously must be located on the route of the ROM) type:
WINDOWS
Code:
LGExtract.exe -kdz V10X_xx.kdz
LINUX
Code:
wine LGExtract.exe -kdz V10X_xx.kdz
Click to expand...
Click to collapse
and you press Enter
NOTE
Where it saysV10X_xx.kdz must be the name of the ROM, for exampleV10A_00.kdz
When the process is complete will see a file with the same name as the ROM, but with the extension .cab, for example, V10A_00.cab
Unzip it and will the DZ and a DLL file
To unpack the DZ type this:
WINDOWS
Code:
DZDecrypt.exe LGE610AT-xx-VxxX-XX-XXX-xx-xx-20xx+x.dz
LINUX
Code:
wine DZDecrypt.exe LGE610AT-xx-VxxX-XX-XXX-xx-xx-20xx+x.dz
Click to expand...
Click to collapse
And you press Enter
NOTE
Where it saysLGE610AT-xx-VxxX-XX-XXX-xx-xx-20xx+x.dz should be the name of the DZ, for example:LGE610AT-00-V10b-EUR-XXX-MAY-23-2012+0.dz
We already have the ROM in BIN format, now you have to concatenate the files SYSTEM, so we use the console and...:
WINODWS
Code:
copy /b "system.img.ext4_
[*]" "system.img"
LINUX
Code:
cat system.img.ext4_* > system.img.ext4
Click to expand...
Click to collapse
And you press Enter and you can delete the files system.img.ext4_0, system.img.ext4_1,..., system.img.ext4_6 (version DZDecrypt.exe v1.0c+ does this job automatically)
Now we'll have a list like this:
Code:
amss.bin
boot.img
boot_logo.bin
emmc_appsboot.bin
oemsbl.bin
partition.bin
persist.img.ext4
qcsbl.mbn
qcsblhd_cfgdata.mbn
recovery.img
system.img.ext4
Click to expand...
Click to collapse
Files .ext4 are you can rename to .img and mount as one drive in Linux or WIndows with Winimage manipulate its contents
LINUX:
Code:
mkdir system
sudo mount system.img.ext4 system -oloop
To disassemble
Code:
sudo umount system

With this I believe that we have done, if something is missing or you have any questions to ask without fear.
