I initially followed the Complete How-To on How to Mod Your Phone (2.1 ROM, O/C, MM, Boot Animation, etc) guide to root my Milestone. But my phone told me that "failed to verify the update.zip"
Then I started searching on google and finally found that I need a totally different update.zip for Milestone to root.
Now I've successfully rooted my stome. Can I proceed to follow the rest parts of the above guide to install the ROMs for Droid such as Ultimate Droid and Simply Stunning?
