Kindle Firmware 5.10.2 Downgrade Failed
I was forced to update my Kindle software firmware (KPW2) to the latest 5.10.2, but I dislike it as I can't back up my Kindle books as before. Then I downloaded an older version (5.4.3.2) from Amazon server. But the truth is that "Update Your Kindle" is grayed out, I failed.
After I connect my Kindle to PC again, I found that the newly downloaded bin file has gone. What's wrong? Does Amazon force us to downgrade firmware 5.10.2?
