HELP Nucleus Nano II - DF/AF popup keeps appearing after firmware update (Hand Wheel 23.10.25/ Motor-S 2.2.4) RTWP
Hi everyone,
I'm having a strange issue with my Tilta Nucleus Nano II after updating the firmware.
Current firmware:
Hand Wheel: 23.10.25
Motor-S: 2.2.4
The update completed successfully, but since then I've been experiencing several problems:
A DF/AF popup keeps appearing on the Hand Wheel screen.
Whenever this popup appears, the focus wheel freezes and won't respond.
Once the popup disappears, the wheel works normally again.
The System Reboot option doesn't work. I select it, confirm, and nothing happens.
I already performed a Factory Reset, re-paired the motor, and recalibrated the lens, but the issue is still there.
Sometimes the motor also doesn't complete the full travel until the popup disappears.
I also tried connecting the Hand Wheel to my Windows PC using different USB-C data cables, but the computer only charges the device and doesn't recognize it.
Has anyone experienced this after updating to Hand Wheel 23.10.25 / Motor-S 2.2.4?
Is this a known firmware bug? Is there any way to reinstall or downgrade the firmware?
Any help would be greatly appreciated!
Thank you!
