JasJar ROM update - Another brick hits the wall

[oddball]

I have downloaded the new Shipping ROM update from ClubImate.com (uni_cdl-me_11238_132_10301_ship.exe) and tried installing it onto my JasJar with a horrible result: it's now only good to use as a paper weight Initially everything looked fine; the ROM utility detected the device and correctly displayed the existing versions of CE image, Device Extended image and Device Radio image, along with the versions it was going to upgrade to. It reset the JasJar (what I'd think was erasing the current versions), but has since been unable to install the upgraded versions. Result: a (virtually) dead JasJar :evil:

I have done the following in order to try and get it up and running again:

1) Several soft and hard resets - the best effort is a screen (with no back light) saying 'Serial' at the top and 'v0.60' at the bottom.
2) Uninstalled ActiveSync and tried reinstalling both version 4.10 and 4.1
3) I have tried to complete the upgrade procedure on two different PCs; one running WinXP SP2 and Win2K SP4.

Despite these efforts, the ROM installation utility is unable to detect the device (ActiveSync's device detection has been dodgy from the word get-go, despite WinXP detecting it every single time - although saying it's unable to identify it) resulting in the following error message from the ROM Update Utility:
In the Dialog's title bar: "R:3030 D:21200 U:11000 P:857873 - CB1" and the message "Error 101: Connection Error".

Please, please, please (with sugar ontop); can anyone of all you clever people out there offer some help or hope?

Thank you very much :!:
