I have one Leaf Aptus II 12 digital back with Mamiya 645 mount. Recently it just got stuck in the middle of starting with LED in orange color,
no matter whether I tried to set up tethering mode or used CF card. Let's call this back as Back #1. I got one new ebox for Leaf Aptus II 12 back but with V mount. Let's call this new one as Back #2. I have exchanged every board between these two backs and finally focused on Power PC board. Actually I can fire up Back #1 when I replaced Power PC board of Back #1 with one from Back #2. So it's clear that this part is broken. Unfortunately the ebox changed my back into one for V mount. I checked the Power PC boards and found they used exactly same IC chips. So it maybe possible to update this ebox with firmware for Mamiya 645.
My question is how to do this?
Many thanks for discussion.
