Any ideas?

*EDIT* I accidentally got into the recovery menu and chose "reboot to recovery", but RKDevTool still didn't recognized the device (no device found). And when I used USBView I found out the device was in fastboot mode. But I don't know if that's helpful or not. I can't find much about fastboot on rockchip yet.
Is your device still running Android 6? If your device is still running Android 6 it is very likely that you don't have fastboot mode.

Based on my experience fastboot works only if the rockchip onyx device is running Android 9. Since the loader mode is working you should be able to upgrade your device from Android 6 to Android 9 by using the official upgrade tool. The upgrade tool would work on the LOADER mode.
