My new Kindle Paperwhite is running on the 5.10.3 firmware.

I would like to jailbreak the device if possible and began to follow a guide which said downgrade would be needed. So to begin with I downloaded the 5.3.5 firmware and copied it into my device directory.

However, when I go to update from my Kindle, I get a message that this is an invalid file for update. And the device actually seems to delete the firmware itself!

It seems Amazon installed some control to prevent downgrading? Is there any way to get around it and successfully downgrade and complete a jailbreak?

Thanks for your help.
