Cool [Q] Help me to get rid of JB update for LG E615f

Hello Friends,

I am having a LG E615f.
One day I found that JB update is available for my device and I updated it immediately.

But now I want to get rid of this JB update and want my ICS back.

I have tried so many times to download kdz (V10) from " lg-phone-firmware, com /index, php?id_mod=12" but it showing "No Data Received" error.

can anyone help me out..
