A little knowledge
KDZ is the official format that uses LG to update their devices.
Each device has different content, in this case, the LG P700 (L7) contains a DLL and a DZ file.
DLL is a library and the DZ is a tablet in a series of files, which are known as firmware BIN.
A series of tools which I list below are needed to be able to compile a ROM:
All these programs run in Windows
- DZCreate packaging DZ (Copsfrance) archives
- DZDecrypterr unpacks DZ (Copsfrance) archives
- UpTestEX compiles files KDZ. (to make it work first should run windows_enable and activate it)
First of all, with the help of DZCreate package archive DZ, follow the instructions in Copsfrance
PROCEDURE
Here I will try to explain how to create a firmware flasheable in format KDZ for LG P700 L7, L3, L5, or any device with this structure.
We will use the program UpTestEX, this serves to create a KDZ file and also for flashing or test firmware.
We will have to have created the folder structure, only to have an order, this is the same that suggested us Serj
c:\newFW\
c:\newFW\apps\ (where have all the applications and programs)
c:\newFW\OUT\ (where will be stored to the created firmware, eye that will erase that contains)
c:\newFW\Source\ (where we have un-compile and custom firmware)
c:\newFW\Temp\ (this is obvious, temporary directory)
COMPILING KDZ
{
"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_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
1-. Select the Flash system, for the L700 select 3GQCT
2-. Work Directory: will have to put the path where to save the created KDZ firmware
3-. Version: the name of the version that we are going to compile.
4-. Select model.dll: the path and name of the DLL for the phone, this is extracted from a Stock KDZ, for the L7 is QCT_P700_20120706.dll
5-. Click on the arrow next to Add and select DZ and add archive DZ
6-. Mark Merge 250-390MB size file:
7-. Now click on Merge to compile the firmware in a file KDZ
That's it, I hope it helpful.

Hello Homero,I have a little problem....When Opening UpTestEXOriginal,the program starts but it does not let me do anything,all entries are blocked and I can't do nothing...why? Running all as admin

---

To run UpTestEX, first you should run windows_enable and activate it. Activated by clicking on the icon of the 3 window that appears next to the clock in the taskbar.

You will find the QCT_P700_20120706.dll to unpack the KDZ, but you can download the DLL from the L7 from the tutorial in Spanish [TUTO] Crear ROM en formto KDZ para el L7

for optimus L5 which model can I use
Hey, after that I've decrypted I got these files:
amss.bin qcsbl.mbn recovery.img
partition.bin qcsblhd_cfgdata.mbn system.img.ext
I've edit system.img.ext and I think I need to create the dz with dzcreate but in the ini file I dont see the config for L5 E610.
So where can I find the config for optimus L5 ?
Thx
Finally I could sove this, using DZExtract.exe -x and the config for E610
[E610]
Chipset=MSM7x27
DZVersion=0x03
SplitSize=0x05000000
SubFiles=0xB2800084
SubFilesHi=0x0000008D
SubFileType03=amss.bin
SubFileType08=partition.bin
SubFileType18=qcsblhd_cfgdata.mbn
SubFileType1A=qcsbl.mbn
SubFileType1D=system.img.ext
SubFileType1E=recovery.img
SubFileType20=emmc_appsboot.bin
SubFileType21=persist.img.ext4
SubFileType23=oemsbl.bin
SubFileType24=boot.img
SubFileType28=boot_logo.bin
exactly same than P700

extract the files from the DZ, and use the KITCHEN to create fleshable.

Anyone can share any new tool to pack kdz , that works on Windows 10 and Nougat ?
It would be a really helpful tool to have.
LG should share those tools normally....

UPDATE: kdz is invalid. LGUP will not flash it. I should probably mention that patched the boot img with Magisk and merged boot.bin, recovery.bin and the dz.
