Hi @Joenoodoe ,
yes, you can upgrade to V02_00_00 and then downgrade back to older versions. (i.e. V01_01_07)
from freev2g.
I'm not so sure about that - I upgraded an EI to V02_00_00 (in a futile effort to get the reference app actually working), and now it refuses to downgrade.

Hi @ColinCGC the V02_00_00 checks the validity of the certificate before verfiying the signature of the firmware. Have you set the time on the Whitebeet? See user manual "12.3.1 Set Time"
from freev2g.
No, I have not set the time, that should do the trick if it's checking the certificate. I won't try it now (as V02_00_00 is working ok), but will bear in mind for future updates, thank you.

I can confirm that after setting the time, i successfully downgraded the module from v2 to v1.0.7. But i think it would be better if software updater do this by himself before starting the update procedure
