How format my HTC HD2
SOURCE: HTC HD2 they gave me the wrong download for english
Well with the phone turned
off, press
and hold
the VOLUME UP
and VOLUME DOWN
buttons, then press
the
END/POWER
button shortly
and release it. You will then see a message
on the screen asking if you're sure about resetting it. If so press the VOLUME UP key. It should boot shortly after that.
Goodluck!

hello,you can kindly follow the instructions below to reset your mobile phone totake it back to it's factory default settings,this will automatically make you loose all the datas you have on the phone,so before you intend to do the reset format,i will advice you do a file or data back up on your system so as not to lose your informations
1.with your thumb or finger open the back cover by lifting up the left side of the cover.
2.the reset botton is located at the bottom left below the battery compartment and the simcard slot.use a small object with an unsharp,pointed tip,such as a toothpick to press the reset botton.
your phone restarts and dislpays the home screen,
3.to replace the back cover,secure the right side of the back cover first and then press down the cover into place.
please kindly rate this solution if it's helpful,
take care.
