I just tried to upgrade and RB600 that had 3.0rc10 on it. It never came back. I have 4 more of these boards and as I pull each one from the bags and plug them in they all have the same version.
Is there a bug with upgrading 3.0rc10 to v3.30?
by “never came back” you mean what specifically? can you check serial console output of this device?
