Firmware Update Kindle firmware 5.16.3.1

[Quoth]

I think I converted an NTFS to ext4 once keeping data intact. I did have a backup just in case. Maybe Jan 2016. But I could be wrong.

My main worry is that they will begin to apply filtering to the set of files accessible via MTP. It would be easy for Amazon to block access to purchased book files, Scribe notebooks, and any other data that they want to keep out of the hands of consumers. That would do a lot to improve the security of the Kindle platform from their standpoint.

A counter argument to this is that Fire tablets also use MTP and there is no such filtering, security issues notwithstanding.

I cannot claim to understand Amazon's motivation for this change: why fix what is not broken? There are some benefits (no file corruption) but also deficits (mostly for non-Windows OS's).

I tend to agree that this is preparation for future Kindles with a different file system and perhaps OS (Fire OS lite?).

There was a comment in 5.16.2 thread saying that there are security vulnerability that can be triggered via intentionally corrupting FAT32 partition. Such attack is not possible via MTP.
