I just recently purchased a powerbook g4 (1.33 12 inch) from PowerON Services. I turned it on for the first time and I was prompted to update to stuff ( osX being one of them) It then froze while installing the updates. Now It wont boot, it is stuck on the grey screen. I tried loading from a tiger disc that I have but that didnt work. I just get a funky message saying to hold the restart button. Any words of wisdom?????? also note i tried resetting PRAM and tried booting in safe mode.
