[TUTORIAL] Go back to LG ICS 4.0.3 when coming from CM10 - Optimus L3, L5, L7 Android Development

Hello everyone! As Some Users have this problem,and many others of you can have it too,I'm writing this guide to get back to LG's ICS when you're coming from CM10. This also works for Unbricking your device.
Warning,Dragons Ahead! BEFORE YOU START DOING THIS,I'M NOT RESPONSIBLE FOR ANY DAMAGE TO YOUR PHONE,THIS HAS BEEN TESTED AND WORKING!
Requirements::
A Windows Based PC(This has been tested under Windows 7 SP1 64-Bit,I'm not sure it will work under Windows 8)
L7 With CM10 on it
Homero's V10K with CWM,ROOT and Unlocked Bootloader which you can find here: http://forum.xda-developers.com/showthread.php?t=2176430 credits to Homero for making the KDZ.
KDZ_FLASHER which you can find at the end of the post.
LG USB Drivers Installed
ADB which you can find at the end of the post.
So,Let's Start!
1. Once You've Downloaded Homero's V10K,Extract the ZIP and you will find a .KDZ file.
2. Now Download KDZ_FW_UPDATE.zip and extract it,then open the folder where you extracted it and Start KDZ_FW_UPDATE_EN with Administrator Rights (Right Click on file and select Run As Administrator...)
3. Once the program started,in Type select 3GQCT and in Phone Mode select EMERGENCY, then in KDZ File select the precedently downloaded Homero's V10K kdz file and press open.

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
4. Make Sure your Phone is connected to the computer in EMERGENCY MODE( Remove the battery from the phone,then while pressing Vol+ Connect the usb to the computer,a yellow screen must come up showing EMERGENCY)
5. Once you've done this,press Launch Software Update and let it work,the procedure takes about 5-10 Minutes,so don't worry.
6. At the end of the procedure the phone will reboot and an LG Animated Logo will come up,and after some minutes KDZ_FW_UPDATE Will say you that there has been an error,Don't panic
7. With still the phone connected to the PC,Download ADB zip at the end of the post and extract it in your C:/ Drive,then open up CMD and write:
Code:
cd ADB
adb devices(just to make sure that the computer recognizes your phone)
adb reboot recovery
8. Now your phone will reboot in CWM Recovery, just do Wipe Data/Cache,Wipe Cache,Wipe Dalvik(Which is situated in Advanced Menu). When you have done this,select Reboot System and wait for your phone to finish the boot,and ENJOY!Good as new! :victory:
That's all,I Hope I could help you!
Thanks To:
-Homero2 for making the V10K KDZ Flashable with ROOT,CWM and Unlocked Bootloader

hi wolf, follow everything on your tutorial but my phone stock on boot animation. Any recommendation?
Edit: Phone back to live again, but using the button combination. I was not able to boot using the adb command.
Thanks to you and homero for the guide.
