I just installed the alpha-21 rom (HTC Desire with Sense) from MoDaCo to my new Nexus one after unlocking and rooting it, and everything went fine I thought but even though it was the most recent version when I reboot all I get is the HTC white screen and the phone reboots to it over and over and over. I removed the battery and then put it back in and tried to boot into fastboot bootloader by holding the ball and the power button but it would not do it, just the white screen saying "HTC simply incredible" or something like that. Please someone help me get back to bootloader so I can run a recovery. THANKS!!!
