I have an HTC HD2 I bought from a friend yesterday and it had WP7. Apparently some of the files of WP7 were on the SD card and I didnt know and erased them. Now it will not move from a black screen. I would like to know how can I make it just like when you buy it from the store. I am not very good at technical language. I´ve read that you have to use a boot loader or something so I would like to know if some one could help with the instructions of how to get it back to Windows 6.5 or Android (2.2 Froyo) right from the that black screen I have.
Thank You!
