just got a Space, amazing…. :-)))
it was on 4.0 firmware, i updated it to 5.2. I saw on the space support page notes about 5.4 firmware…. can't fond it anywhere, and direct update do not find it too.
what is the latest firmware for space?
The latest update for Space is 5.2.0[6]. Maybe, you read about the 5.4 update for H9? In any case you seem to have already installed the latest Space release.
