Did you backup your froyo rom before upgrading to gb?? If you did you could simply flash your recovery rom back to the phone....if not, you'll have to search thru the site here to find a froyo updated zip....id help but I just finished changing over to gb and I lost my root....along with tethering... I just dodged a HUGE bullet...so I finally got my recovery to take the gb update.zip...took about 10 minutes to upgrade.... when I went to reboot...it got stuck on the droid eye screen for 30 minutes....and I tried rebooting into recovery, would not let me into recovery....somehow, miraculously after 10 minutes of me freaking out...my phone responded and TAda! My droid pro is now running gb! !! Scary ordeal though....ohh and I lost my root wonder iii z4root works with gb??
