I've done this on some other HW supporting RK3399, the NanoPC T4
I tell here what I've done on this platform to get RK3399 in bootrom mode
You need a USB-A cable to USB-C plugged into toe USB-C port
Press MASKROM and Powerup (maybe also reconnect your powerplug)
Also they is maybe some issue with the USB-C cable, due the flipping mode of this plug.
Try to "reverse plug" the USB-C port.
Maybe there is some difference here, but I must check the schematics ...
Also it's possible, you don't need to connect USB-C in the first place ...
