Hmmn... That's sad, if it's from the original launch date and Bootmii as Boot2 not installed... Can't say we here on Wiihacks didn't warn you of the dangers of messing around without Preloader or Bootmii installed... Okay, enough bashing : P
Anyway, what happens when the green light comes on? Are you able to eject the disc? I mean, there are some chips or wiikeys that I believe may be able to help you, but if I was in your position, I would probably send it to Nintendo. It's virtually a free repair but, they will most likely update your Wii to firmware 4.2. Errmm... What else... Umm... I'm unsure if they fix the boot2, if so then bootmii won't be your friend anymore. This guide by Messie (clicky) would help you get your Wii-hack on again : )
Also, I haven't read much of Messie's guide, so sorry if I'm reiterating what they've said but keep in mind that Preloader has stopped being released, additionally Preloader searched for the old HBC title ID (HAXX) as opposed to the new ID (JODI) thus installing the newest HBC isn't exactly safe as Preloader can't boot to it.
Sorry if none of that made sense XD But good luck : ) And contact me if you want me to refine anything, I'll do my best : )
