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.
Of course, with Jmz Android Dual-Boot for HTC HD2, I need to have 1 click to enter Windows Mobile too. But it is worth it. It saves lot of clicks when loading Android. It is must install application for those with Android on their HTC HD2.
