Thanks to XDA member ” jmztaylor” , he has now given us a cab file ( 147 kb only ) when installed allow us to have dual boot option. Immediately after the splash screen and right before the phone fully boots, it gives you the option to either load Android or Windows Mobile.
QUOTE : So this is a dual-boot app I wrote for the HD2. This just gives you an option during boot to choose Windows Mobile or Android. You must have android already installed to the root of your sd card. If you are using the latest android release be sure to rename zharet to haret and the default.txt file to startup.txt and you will not have to tap run in haret anymore.
Updated to v2. Now automatically launches CLRCAD.exe.
