Root HTC Desire and upgrade to Android 2.2 (Froyo)
Hi Guys, finally decided to root to get Android 2.2 and this is the simplest way to do it I Found. (everything is free and no extra hardware is needed such as a goldcard)
1. Uninstall HTC Sync and the HTC sync driver if you have them installed. (stops the root, can reinstall afterwards).
2. Download unrevoked (this roots), the 2.2 rom (the android 2.2) and the 2.2 rom radio (goes with the rom).
3. Copy the 2.2 rom (ota22.zip) and the 2.2 rom radio (32.43.00.32U_5.09.00.20.zip) to your sd card.
4. Run unrevoked and follow the steps to root.
