All of the above are fair questions, I saw no mention of genuine? There are a lot of fakes out there of dji props and many are rubbish. Are they 9443 or 9450?
Take a look at these for a comparison:

Apologies for not having the firmware revision to hand but recently I calibrated my FC40 and it offered a firmware update. Knowing what horror can ensue I skipped it.
Has anyone used this recent update and what was the outcome?
I'm pretty sure you have to update each battery 1 at a time after the firmware update. It will only update the main phantom firmware once, just power down and change batteries to update the next battery.
