I was going to say “Read Sparkyws’s post above” but he beat me to it 
Just to add that I’ve just tested his method and it works - gives the option to regress as far as 1.02.000

Yes I feel a twat again on here.
Sorry I’ll try on a minute when bored with England game… give me 2 minutes
Less haste more reading and concentration pillock!
Thanks @SparkyFPV
This method allows you to refresh or downgrade the mini 2 firmware or refresh as in a clean install

Little reading later. Thank you, now we wait.
Successfully done. All batteries now updated.
Little tip don’t skim read in work and presume you know what you are doing when you get home.
Yay, glad it worked and you managed to follow my instructions! in the end 
I always update the firmware this way now as I feel it’s a better option than using the radio connection.
Wired Firmware update is the way to go…
I’ve done a wee video about me trying out the updated ‘smoother’ fpv mode on this little drone. The first 3 minutes are about updates and you probably all know about these already.
Worth a look if you’ve got a few minutes to kill. I quite like it and will try and use this mode a little more often.

Well I have have never tried FPV(ish) mode with my Mini 2 but after watching this, I reckon I’ll be giving it a try soon. Have loads of open space around here to give it a good test. Thanks for sharing, looks like fun and as you say, getting those nice smooth turns, when following a track is going to take practice.

Thanks for the update re firmware updates. Moved your post here to keep all such info in one place.

For those worrying about range after the recent update, this guy managed 5.3km albeit in a rural location where interference is likely to be minimal…and in the US so none of the crippled CE power output

All three batteries now at 3 solid, 1 flashing light whilst tucked up safe and sound in the hub.

Mine still aren’t discharging for some reason! I’ve given up all hope 
What if you store them outside of the drone/cradle? Checking the charge on them every so often will stop them from discharging also
I have left them for over a week before checking them. I was aware that checking the level resets the clock. Someone suggested they discharge after about 9 days now. To be honest, its rare that they don’t get used within 7 days so I’m not going to achieve this under usual circumstances. I have given up worrying about it for now. Perhaps ill revisit it in the future.

When it flags up the battery firmware update, it updated the battery currently installed in the drone and you need to power everything down, remove the updated battery and insert the next and so on, until al batteries have the latest firmware. However that’s not what I experienced when they apparently fixed the discharge problem. It flagged it up with the first battery, but not for the two others… However I have noticed that each battery dorps to around 95-96% after play 2-3 days of being left in the hub and not used. No idea how far it drops after that time, as I usually go flying, every weekend, but al appears to be working ok at my end, whereas before, they were definitely not discharging automatically even after a week left in the hub… I don’t undertand how this is supposed to work properly, if it only updates one out the three batteries. Could it be the updated battery, updates the others, when all placed in the hub or when fitted into the drone, the system already has the update downloaded, and updates al remaining batteries without having to redownload the firmware, for each one
There are two methods to update the firmware in subsequent batteries.
- The force-close method
Or
- The have-a-little-patience method
But as you suggest @Andy601960 you must update each battery.

Excuse the newbie question, but how do I tell if each battery firmware has been updated?
Many thanks
Turn off the drone replace the battery and then restart the drone. If the battery needs an update it will tell you on the fly app to update.
If you are on Android, force restart Fly when you’ve changed the battery.
