Forect Star Passion HD v1.5 (formerly 1.4)

Question

Iortecstar passion HD

I have just uploaded v1.5 and new firmware. Prior to this the previous version 1.4 worked fine (wish I'd not fiddles.!)
Version v1.5 has loaded but although it shows in the window (as good) the system won't proceed to load onto the TV screen.

How can I revert to v1.4 or reset to factory settings (can't gain access to system).

A link to a site with v1.4 available would be a good start. This is available on Laurals.net but nowhere to login to access it.

Help and advice appreciated

thanks in advance.
