finally! i managed to revert it back to windows mobile
all i did was install HSPL3 (no roms needed), rebooted and booted without any errors all i needed was my laptop with newly installed wmdc (for some reason my desktop which also has wmdc didnt work, rlly have to re-install on that one)
now i have find an android rom that unlocks the hidden ram of my htc hd2 or will just stay as windows...
btw can u recommend good ROMs you know? thanks
