uClouds & Parasite firmware

I got a second hand 8HP Clouds (similar to this one), and having troubles flashing the Parasite firmware.

I followed this procedure to upload Parasite 2.1, but it seems I can’t achieve the behaviour of pressing the black buttons simultaneously to access the additional modes.

In spite of this, the factory modes seems to work properly.

This is not a Mutable Instruments product. :confused:
