I'm coming from an original droid and flashing roms was really easy but now with the X I'm a little confused. I'm rooted, have bootstrap installed, and now I want to try some custom roms. I'm currently at 2.3.3, do I have to flash to a different system version before I can install new roms? I've done a lot or reading but can't seem to find the right information on this. Thanks for your help!
