I decided to root my G1 the other night and followed the directions for Cyanogen 5.0.8. I ended up running into the problem where it gets stuck on the G1 logo screen. After a couple hours of not getting it to work, I decided to revert it to the original stuff. I followed the steps to reinstall the original bootloader and recovery and then the original RC29 image. Now when I start my phone it goes straight to the bootloader(RGBW screen). I can still get into recovery mode, but its obviously limited in options. Am I SOL or is there a way to fix this?
