Question [Q] [Help] Problem when flashing any ROM

Well, as the newbie I am, I dunno why this happens to me... When I try to flash any rom at my LG Optimus G E975 it shows up this error. Always. With every ROM. Why does this happen? Here's the error I always get, tried Cyanogen and PAC-man

Quote:
asset failed: getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975"
Why does this happen and how can I fix this? D:

And the LG Update Software recognizes the devices as the LG Optimus G E975... :/

EDIT: after hours of investigating, wouldn't this be solved just by copying the "getprop" binary?
