First of all, connect your device when it`s in bootloader.
next, open Windows Mobile Device Center and in connection settings uncheck Allou USB Connections.
next, goto contol panel-administrative tools-services and start windows mobile device connectivity and windows mobile device 2003 connectivity
next, goto device manager and find your device and update the driver to the one from AS 4, i attached it, wceusbsh.inf.
then, kill wmdc.exe with any taskmanager
You are Ready. run ruu or connect MTTY. I guess that vista default driver uses another port, not WCEUSBSH001, that`s why we have to use the old driver.
