Dual R3 firmware 1.5.2 the curtain turned into a mess

It was all working perfectly until version 1.5.2 of Dual R3 arrived.

When I tell Alexa to set the curtain to x%, the curtain moves a little and then stops. I removed the device, tried to calibrate it, but without success. Calibration closes the curtain, but it doesn’t return. I can’t do manual calibration because I don’t have a switch.

This situation is complicated, everything was working fine until I updated the firmware.

And now, how do I get out of this predicament?

Hi @Daniel_Zhan, please, any chance or possibility to roll back the firmware to the previous version?
