Normally, we upgrade HTC HD2 Windows Mobile ROM using RUU with USB cable. It is faster than using SD card method. Then why do we need to upgrade HTC HD2 ROM through SD card?
- Windows Mobile 6.5 ROM is corrupted
- Remove HSPL3 ~ SPL-2.08.HSPL
You cannot upgrade HTC HD2 Windows Mobile ROM using RUU when you cannot even connect through Windows Mobile Device Center or ActiveSync. And the only way to remove HSPL is to use SD card upgrade ROM method with official HTC HD2 stock ROM.
