Default F320-L and lightning

Hello

I have a LG G@ bought in Seoul in December 2013, and I got really a hard time to root it. Nothing worked, but finally I could root it with the Chinese app 360, and also had to update with a ROM normally for D802 (so my phone tell me it's a D802 now). It worked well, but no 4G, no update, so I wanted something new.

And I so lightning v3 should work I downloaded the last .zip, but when I'm in recovery mode, at 60%, it fails, and can't use it

Anyone has an idea?

Thanks
