After some research about how to get Android 2.2 on my HTC Hero (because HTC haven’t planed to port Android 2.2 to it yet and because I need it now), I finally fell on a team called “VillainROM” [source] who created a project called “FroydVillain” that consists in porting Android 2.2 on HTC Hero.
Their current version is 1.5 and it seems to be quite stable. The only problem is that I would have to flash my device risking to brick it and because it is not an official release of Android, my warranty probably won’t accept to fix it.
I fell on this website [source] that says that it is very unlikely to brick the phone, so it’s decided, I will try to install it.

DO NOT do this
