You're trying to use wrong jailbreak method for the device you're jailbreaking.
PW1 is the only Kindle on v5.x firmware branch that can be "downgraded" to older firmware
without requiring to already be jailbroken.
Simply download and copy the older 5.4.x update bin > copy it to your PW1 and
without ejecting from your computer and without disconnecting the USB cable press and hold the power button on your PW1 for 20 seconds or more to force a reboot. On reboot it will start installing the older 5.4.x firmware.

Once downgraded you simply use the old jailbreak that supports "up to" firmware 5.4.x to jailbreak.

After successful jailbreak install the newest version of hotfix >
update back to firmware 5.6.1.1 > reinstall the hotfix again. And the rest of the stuff that you need / want.
