[LG Optimus G (International)] beefslayer:
Miracle

Wow, my problem is solved.

1) I tried the KDZ method again, ran into the same problem, stuck at fastboot screen.

2) Disconnected device and went into Download Mode again and connected back to the PC.

3) I just let it sit there, while looking for other solutions when suddenly..

4) It starts to boot up! (Altho it showed one error message that was too small for me to see).

Sweet!!

Ruined my Saturday though but better than perma-brick!

Apparently, the log shows that the process didn't complete though.. Confusing
