It seems this is again not possible on PUI 4.5.30.
If I do: fastboot oem help
(bootloader) oem help
(bootloader) oem setenforce (0~1)
So it seems like splash unlock and unlock are not available options even though I have the property sys.oem.unlock_allowed 1
Maybe I have installed the incorrect USB drivers? Can you link the Pico's usb_driver.zip if possible please.
Thanks so much in advance,
