Download Bootstrap(from the market)
That allows you to boot into clockwork recovery
then go to the ROMs section of this droid x forum. Download any rom you like. Im running the new gummy and its running great!
Each Rom usually comes with its own set of directions but usually it involves the following
Place Downloaded rom onto sd card
Boot into Clockwork
locate zip from sd
choose zip from sd
install zip
reboot
enjoy
Some require to mount the system, others require to wipe/factory reset. just read the install instructions included in the thread
