HTC Serial Debug Cable

This cable will allow you to connect directly to the debug log and oemsbl.
In fact, it let's you use the serial interface for usage with HTC mobiles.


So, just use a USB-to-Serial RS232 cable like the Nokia DCU-5, cut the end that would lead to the mobile and connect it to a HTC mini usb 11 pin connector the way it is shown above.

You can also use a max3232 schematic instead.
