Hello all I have successfully downgraded my LG Venice from LG730ZV6 to LG730ZV5 to gain root access again by using Bin4ry's exploit. This tutorial will also unbrick a soft bricked phone. WARNING: If you do something wrong, you can hard brick your phone. I take no responsibility if your mess up your phone in the process. Special thanks to androidlover @ rootzwiki i used his tutorial and edited it to work with the venice.
Tools & files you will need:
1.KP500 tool
2.LG730ZV5.CAB file or LG730ZV8.CAB file
3.LG Mobile Support Tool (internet connection needed for tool to work) & LG drivers
Instructions:
1.Install LG Mobile Support Tool & drivers
2.Extract the KP500 tool into a directory (i.e. C:\LG_Tools)
3.Move the .cab file into the same directory
4.Power off your device
5.With your device off hold down the vol up + vol down
6.Plug in the usb cable while holding both buttons your device should now be in download mode.
7.Run KP500-Utils-EN.exe as administrator
8.You will get a list of options choose I "Flash with assistance (file .cab) enter the letter I
9.Enter the Phone Model = LG730
10.Input the full path to your cab file including .CAB at the end (i.e. C:\LG_Tools\LG730ZV5_01.S5_00.P61009.CAB)
11.Input the full file name of your cab without the .CAB at the end (i.e. LG730ZV5_01.S5_00.P61009)
12.Watch as the LG update tool pops up. It will most likely tell you that your phone is disconnected. This is normal and to be expected just click restart.It will find your phone and go thru extracting the cab file and then extracting a .bin file.At this point if you did something wrong with driver setup you will get a page error. If you did it right, you will get a percentage indicator that goes past 15%. Every so often a message will go by about "model dll message not found". This is normal.
13.Wait for your phone to finish flashing and let it reboot on its own. if stuck on a boot loop do a factory restore after flashing. Enjoy the fact that you can now recover your phone if you do something wrong (in most cases)
