PW2 Does pw2 have a diag mode like kinde4?

Hi, I just got a kindle pw2, so I want to jailbreak it. But I found the jailbreak method is quite different from kind4.

I try to enter pw2 diag mode like kind4, but it does work.

Does pw2 have a diag mode like kinde4? If it does, how can I enter it?

Thank you.
