LG Transpyre | I need a stock rom |

So I kinda messed up.
I soft-bricked my phone. Out of impatiences I didn't
back up my phone. Now my phone is stuck in a boot-loop.
I need a stock rom for my phone so I can push an update through the SD.

LG Transpyre
LG(E) VS810PP
Android 4.4.2

I don't remember what I did last to put it in one.

My phone still boots up. Gets to the LG boot screen then to my custom one.
It stays on the custom loading screen. When I press the power button it vibrates.
Same as with the volume buttons.

It won't load in to Safe Mode
and ADB can't find my device.

I am on Linux (Debian Jessie) so any support will be nice.
