@eureka : but why only on mine ???
@knc1 : mine was one of the first US PW delivered, so it arrived with 5.2.0. I had Jailbroken it, to install kindlet (or puppies, or kitty, or whatever it is called now) and Collections Manager. It upgraded without my consent
while i was downloading a book. After the JB Failer yesterday, I redid the update with the normal downloadable 5.3.0 bin available on the amazon.de site, which is where my Kindle is registered (because I thought it could help). The only file I have is this one, downloaded yesterday, but not the original 5.3.0 file that amazon used to upgrade my kindle from 5.2.0 to 5.3.0
