Hi Thermique,

It sounds like you making good progress with the hardware faults.

I you need specialised help think it would be worth you contacting ChrisJC M-RepairShop see his post Repair, service and upgrade of Meridian legacy products.
Chris does a great job and a lot of people use his services which does tend to make him quite busy. I'd suggest emailing and/or phoning him.

As for firmware speak to your local dealer if you have one, or contact one of the HH friendly dealers that post on here and I'm sure someone will sort you out.

Regards,
Carl
