Update Miner manager firmware of Avalon 2/3, easiest way?

[helipotte]

I want to update the firmware (MM) of my Avalon 3 blades.  What is the easiest way to do this.

The instructions here :https://github.com/Canaan-Creative/MM indicate that you need ISE to do this.  Would it be possible to just remove the EPROM and flash

it with the appropriate hex/bin image?  Anywhere I could download a pre-built image?

Thanks!
