Hi can anyone provide good instructions to update the firmware on the Bp50 preamp?
You can refer to this post: B50 Firmware Version Update 52-452f344c
And the newest firmware here: B50 /BP50 Firmware Version Update 0057-5be7aedf
BP 50 After updating the firmware, the sound control stopped working, the volume itself does not change, there is a reaction of indicators in the application itself on the smartphone, but the volume does not change. I’ve tried different firmware versions from 52, 53, 54, 55, 56. The result does not change.
Got it, thanks.
Already feedback to our team for figuring.
