New Pinephone Pro won't boot, not even in recovery mode

[jmhbnz]

I'm having the same problem. I got my PinePhone Pro Explorer edition yesterday, it's now refusing to boot at all.

I know the battery is fully charged, I've tested it in my original PinePhone.

I've tried holding down the power button, power button + volume up, power + reset button, nothing works.

Plugging in the phone to computer lsusb shows:

Code:

Bus 003 Device 008: ID 2207:330c Fuzhou Rockchip Electronics Company RK3399 in Mask ROM mode

Is there anything else I should attempt before I return the device as faulty?
