Apparently, they have added in more 'downlgrade' protection, in addititon.

This means that if you have upgraded to 5.10.0.2, or have a device that shipped with that, then you cannot downgrade to 5.10.0.1; You have to use the factory version that matches your installed code exactly.

This post is based on what the people who had with 5.10.0.2 reported, and I have updated y device to that version and confirmed.

Code:

181120:161817 OTAController[1270]: E FB02Bundle:FB02BundleValidationFailed:reason=IncompatibleVersion,deviceVersion=3341680009,bundleVersion=3337430015:IncompatibleVersion version
181120:161817 OTAController[1270]: E BundleValidator:validateBundle:valid=false,filename=/mnt/us/update_kindle_all_new_paperwhite_v2_5.10.0.1_factory.bin:Removing update file

I attempted to remove the SP01 header, and then re-write the bundleVersion, but no luck, FB02 images Have to be signed now.

Hopefully this may encourage people to find a new jailbreaking method, that doesn't rely on the factory images.
