Well you should't fart around with your phone if you don't know what you're doing!! Seriously thought there's a sticky on how to unbrick your phone on the Lumia 920 section, it should be very similar
I think I have the same issue. Not a rookie at this at all. I have care suite 5.0.0 (2012.5.5) Flashed to almost complete, then came back saying error reading package, and phone won't load. Stuck in flash mode.
