How do I recover my phone that is soft bricked?

A

AC Question

Currently, when I boot my phone (an LG Realm LS620), it just gets stuck on a grey screen. So, I try to booted in to recovery mode and receive the following errors:
E:missing bitmap stage_empty (Code -1)
E:missing bitmap stage_fill
I am given 3 options in which to apply updates: update from external sdcard, cache, or from ADB. If update from external sdcard is chosen, I get the error:
E:failed to mount /sdcard (No such file or directory)
I have a 16 GB micro SD in my phone right now, so I am confused. If update from cache is chosen I am given 3 different empty folders.
So, currently that leaves me with updating from ADB, however, my PC does not recognize my phone and Windows gives me and error with Code 43. I tried installing the LG Realm USB drivers, but did not do anything. Device Manager shows: unknown device connected (configuration descriptor request failed). I am frustrated on what do and am in desperate need of help.
