Open file explorer in Windows Mobile. Go to ‘Android’ folder in SD card. Click on CLRCAD.exe and click on Haret.exe in the end. This is what I do in order to bring up Android 2.2 Froyo on my HTC HD2 last time. Now I just need to have 1 single click to load Android. Thanks to Jmz Android Dual-Boot for HTC HD2.
