The firmware 5.6.1.1 is considered unbreakable and there is not yet a effective jailbreak for it besides using ttl serial which requires the whole device to be opened up.

Now, through research, there is finally an effective way to perform that. First downgrade the current firmware and then it’s much easier to perform all kinds of jailbreaks.

As I quote:

How to Downgrade Paperwhite 1 Canada from 5.6.1.1 to 5.3.3

Download earlier update file from Amazon: Kindle Paperwhite 1 Update 5.3.3
https://s3.amazonaws.com/G7G_Firmwar...ndle_5.3.3.bin
Disable wifi on your Paperwhite 1 (airplane mode).
Connect your Kindle Paperwhite 1 to your computer (DO NOT DISCONNECT UNTIL LAST
STEP!).
Copy the bin file you downloaded in step 1 to root folder of PW1.
Wait at least 2 minutes after copy has completed.
Push and hold power button until your PW1 restarts (the led blinks orange and
light turns on at the screen).
Wait until the PW1 has installed the upgrade (really a downgrade).
Now you can DISCONNECT from your computer.

Tested and working on Paperwhite 1 I assume it should work on Paperwhite 2.
