EVO II Pro V1 not accepting Firmware V2.7.25

[MannFlight]

I have tried twice to update via the app and once via MicroSD card and the update will not complete. Any suggestions?

others have reported a few issues; what sw version are you stuck on?

I am not sure, all I see are the individual component versions and no overall Firmware version unless I am looking in the wrong place.

First thought is, if your Evo II is bound to two devices, either two transmitters or a transmitter + Live Deck, it won't update. (There's a procedure back in the archives for unbinding in order to update FW)

Brock Inspector, thank you for the suggestion. Success by rebinding the aircraft for each update (same update but for all 3 batteries). This unit was paired with a live deck for emergency response.
To summarize; start the aircraft, put it in binding mode then initialize the remote controller in binding mode by pressing power on and home button together for 3 seconds. the controller will pair up with the aircraft and accept the update. Repeat update for all batteries ( if the update includes a battery software update)
