In a surprising twist, <= actually *means* <=.

Shocking, right.

(So, yeah, that'd be a big nope).

Other than opening the kindle, there is no way to downgrade the FW either, right?

Not even over the serial port on a "Androidized" firmware/hardware combination.
Which includes your firmware/hardware combination.

TL;DR: No, not even via the serial port.

Buy a used PW3, give that PW4 back to Amazon.
That includes the original poster and all others hijacking this thread.

i have no doubt a solution will be found, eventually.... And for now, keep your kindle off the network and away from any updates.

Keeping your Kindle just because you think it might be jailbroken is misleading. There's a very good change the days of jaibreaking new Amazon Kindles is over. seems Amazon Lab126 has learning from past jailbreaks and plugged the holes.

If you bought the PW4 in order to jailbreak it, send it back. Get a Reader that does or can do what you want without waiting for a jailbreak that may never come.
