LG L7 II How to unpack KDZ (and system.img)

[maxx_hr]

OK, let's start:

1. Download https://www.dropbox.com/s/rnqrx7xh4z27zfr/KDZ.RAR
2. Unpack archive and open folder KDZ
3. Drag the firmware file (eg, V10J_00.kdz) on 1.unpack_kdz.bat
4. You get ,cab file (eg. V10J_00.cab)
5. Drag the .cab file on 2.unpack_cab.bat
6. In stock folder, you can find firmware folder with .dz, and .dll file
7, Download https://www.dropbox.com/s/sjb9ff7wmpdxl6a/LGwinTools_1.02.zip
8. Unpack archive LGwinTools, start LGwintools.exe
9. Open our .dz file previously extracted in stock folder
10. Click on 'save' icon (dont work through File ... menu), and choose folder for extraction...

That's it.

To unpack system.img:

1. Download https://www.dropbox.com/s/z7mqlzmobblf0d7/ext4_unpacker_exe.zip, and unpack it.
2. Run the ext4unpacker.exe, choose image file (system), and click on save as ext4. You can't miss, only 3 buttons is available: open image file, save as ext4, and exit.
4. Name it however you want .ext4 and save.
5. Download https://www.dropbox.com/s/5i33dt4n0w2z398/ext2explore-2.2.71%20%281%29.zip, unpack it and run ext2explore.exe,
6. Choose system.ext4, and do whatever you want.

So basically, it turns the kdz into a zip file that can be extracted?

 

[Pecan6]

So i just copy the file on the SDcard and install zip from the SDcard in recovery?

EDIT: Now the phone doesnt turn on..when i turn od it will displayed blue strips and thats all..

No, it turns kdz file in readable format, with possibility to manipulate with files.
When someone figure out how to pack changed/switched/modded files back in kdz, we will have tool to distribute rom through KDZ-s.

So i just copy the file on the SDcard and install zip from the SDcard in recovery?

EDIT: Now the phone doesnt turn on..when i turn od it will displayed blue strips and thats all..

Why did you do that?
This is tool for extract rom files from kdz pack to regular format.
Where did you find a word zip, or zip for flashing in thread?
Flash only regulary kdz for your phone model, or verified rom.zip...

Idk if it is even possible for P705 (never hear anybody did it, or have it).
I know how to extract partitions from dz (and merge system), but what is the difference, or how did you recover P705 with tot file, and why did you didn't with dz?
Anyway, I think you can find more information on lg l7 forum...

Have you any sign of phone in device manager? Try to pull out battery.
If not, i doubt even qpst (with proper emmcbld.hex) help you.
How did you damage jtag pinouts? If you try to recover boot area, with which device?

jtag pin damage is ... TDO , NRST n RTCK. all jtag pinouts are direct to Processor qualcom msm7227A. and that ic is permanently glue.
it impossible to reball n re write if the IC was damage by hot air .
thanks for advice.

You won't get away with that without a very good RE knowledge and the time will not be worth most likely. You can destroy any connection with QDL Mode with wrong files. I have been there. Sorry, that phone is done.
