Somehow, my HTC HD2 crashed and it won’t start anymore. It stops on the startup animation after showing the android logo. I wanted to access the boot menu to do a reset but I disabled menu access and set it to default boot option from NAND.
To get the boot menu back, just press the VOLUME DOWN + SEND/CALL + POWER/END-CALL buttons while your phone is power down and keep presssing until you see the menu.
If you hava a backup of your data, go to AD HardRecovery and do a complete reset. Becareful, all your data will be erased including contacts and saved things.
You can do a backup by connecting you HTC mobile using usb cable on your computer and save important files. The contact file is pim.vol and YES you can restore them later.
