I ordered a Thunderbolt (w00t) and am giving my OG to my mom. I want to keep the phone rooted for the free wifi tethering but I need to get it back to a stable ROM. I've been running liquid but keep encountering minor issues with my camera/gallery/wifi/gps and my mom will not be able to cope with this. She doesn't live nearby so I can't just keep updating her ROM either to fix any issues. She is never going to use any of the fancy bells and whistles so I'm aiming for stability and simplicity. I suppose it doesn't have to be a stock ROM but it does need to be bug free.
What's the best approach here?
