When the Droid X was released by Motorola, a lot of fuss was made about its locked down bootloader. The locked down bootloader on the Droid X meant no custom ROMs for the phone. The modding community was quite shocked with this piece of information, since the Motorola Droid had an unlocked bootloader and that made it a popular phone. However, the modding community did not lose hope and started working on the Droid X. Within a couple of weeks of its launch, the Droid X was successfully rooted by birdman.
Now, the modding community has got another major breakthrough. ROM Manager developer koush has managed to get Clockwork recovery working on the Droid X. He even posted a picture of Clockwork recovery on the Droid X on his twitter profile. However, he did mention that the Droid X bootloader is still locked. He managed to get clockwork recovery working on the Droid X by hijacking the boot process of Android.
Sadly, this means custom ROMs for the Droid X is still sometime away.
