Looking for Fazua Ride 50 v2.04 firmware

[Koenus]

Hello,

I have just bought a Trek E-Caliber 9.6 Gen2 with the Fazua Trail 50.
I want to play with max speed/power settings, but they are blocked in the 2.22 version.
I think that the older 2.04 firmware versions allows more tweaking though, at least with the right access.
I can not find older versions on the Fazua website though.
Could someone supply me that firmware, or a link to download it?

Thanks upfront, Koen
