This tutorial should work for any zip-ROM package prepaired to install from CMR (Recovery).
UrDroid it’s nice Android 2.3.5 ROM for our Leo (HTC HD2) device which I chose from many on XDA Forums, similar to HTC Sensation with HTC Sense 3.5, very stable which not rage people :-). Works very well.. Here’s link to it and this is tutorial how to install it:
Before.. I’m not taking responsibility of bricked devices! RTFM (Read The Fucking Manual) of any flash step. Make backup right now. Battery should be maximum charged in case of any problems (MagLDR doesn’t support charging on turned off device! / You need charging? use cLK loader) – so you should have about 3 hours of non-stress flashing.. after that hours I’ll start to worry ;-)
