Hey Support,

It seems this is again not possible on PUI 4.5.30.

If I do: fastboot oem help

It returns:
(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,

Dear Developer,
Please tell us what you do with "fastboot oem help" and why you use it?

Hey Support,

I use “fastboot oem help” to see the commands available for “fastboot oem”. So when I type that command, it tells me that I can do “fastboot oem help” and “fastboot oem setenforce” but not “fastboot oem unlock” or “fastboot oem splash unlock”. I am ideally wanting to be able to do “fastboot oem unlock” so that the bootloader is unlocked so I can run a command to install the firmware as I have a lot of devices to update. In a few weeks I want to be able to do “fastboot oem splash unlock” too so I can change the splash screen.

Dear developers,
Could you please tell us what is the type of device you use?
The previous method that contains "fastboot oem splash unlock" does not apply to Neo 3 Pro series devices.
For Neo 3 Pro series devices have their own setup methods:
