The HD2 from HTC comes preloaded with Windows,
but if you prefer the
Android OS, you can
download it onto your
phones SD card and run it on
your HD2. Check with the manufacturer or warranty
provider first to make sure
this process will not void
your warranty. Access the menu
option from the
settings button on your phone. Click all
settings, then system
and then power. Click the
back light button, deselect
automatic adjust back
light and press done. Download the Android
file onto your
computer. You can download the file at this
website: gamesquare.co.uk/
froyo.html onto your
computer. Connect the
phone to your computer in
mass-storage mode and unzip the files to the root of
your SD card. Click file explorer on
your phone to access
the storage card. This will reveal the list of newly
downloaded files. From this
list click on the file called
CLRCAD which will cause it
to highlight. Then click on the
file called HaRET which will initialize install process.
Installation takes about two
to three minutes. Tips If the installation is
interrupted or for some
reason does not work,

battery and follow the final
step. That is, click CLRCAD and HaRET from the file
explorer menu.
