    Welcome to Android Central! Did you get them brand new or used? If they're brand new, I doubt that the OS disappeared--it's more likely that either the firmware is corrupt, or there's a hardware problem. Is this happening with both F7's?

    In order to install firmware, the phone would have to be rooted. If you can't get the phone to boot, then you won't be able to root it. Are you able to return the phone and get a refund? Or is it still under warranty by LG?

    It seems like soft brick, i doubt OS disappeared, if its rooted and with custom recovery installed just clean dalvik cache(or just cache) and factory reset it would work fine
