Need help. My english is very bad.
I Jailbroken my 11th generation Kindle Paperwhite. With firmware 5.15.1
I did it using the click once method.
It seems like everything was ok. I haven't tried installing koreader yet.
My problem is that the kindle won't let me turn on airplane mode or reset the device.
How do I resolve this?
For this reason, Kindle updated to version 5.16.4

I lost the jailbreak?
