Hi, I followed the guidelines and am stuck where I sopt autoboot mode, and it displays the following:

Have you managed to continue after this in order to serial flash the firm? PW4 Wifi Model, thank you.

What's your goal here?

If it's to reinstall firmware, you need to enter recovery-util by pressing enter at the next prompt (though this might not be possible on recent firmware versions).

If you're attempting to jailbreak the device, you're out of luck. It's never been possible to jailbreak a PW4 over serial and probably never will be.

I wanted to downgrade the version via serial in order to jailbreak it. This is impossible today?
