Does anyone know if/where version 1.00.27 can be downloaded from or has a copy they can let me have?

The only version on the Humax site is 1.00.26.

I stupidly overwrote the wrong version onto my PVR9300T and now the box is unusable (cannot tune any channels and signal strength is zero on all MUXes) so I assume there must be a slight hardware difference in the later models which have 1.00.27 factory installed.

I have another box with 1.00.27 on it but do not know if there is anyway of downloading the firmware from the box – the WDNOAK software seems one way only.
