Stuck in Serial Bootloader Mode

[goldch]

I have an older VX6700 with version 1.04 bootloader. I was recently trying to upgrade to Windows Mobile 6 and the process died before it really ever got started now I am stuck in Serial bootloader mode. Despite following all the directions I have found here I cannot get the device to switch to USB mode in order to allow me to use the MTTY utility or to re-try the upgrade. I am just about ready to give up - but before I do I thought I would ask any of the Guru's here if there is any way to get the device out of Serial Bootloader mode or to flash the sevice using either the built in memory slot or some other method that does not unvolve establishing a USB connection.

Thanks in advance...
