For reference purposes, does NoDRM's DeDRM plugin still work with 5.18.4.0.1? Thank you

Yes it does. There have been no changes to e-ink Kindle DRM.

If someone reports that installing this update affected the user interface it is likely that it was coincidental with Amazon's servers enabling them remotely. Just the act of rebooting a Kindle will cause it to check for changes to features that should be enabled.



I am a US customer I have have the spacing adjustment feature on three different Kindles, one running 5.18.3 and two running 5.18.4.0.1. On all three it is found under Aa, Font, Spacing.

I've restarted all of my kindles running 5.18.3 and later, to no avail thus far.

Thank you. I will update the calibre thread.

A jailbreak does exist for this firmware version but it’s not publicly available yet; it should be released sometime later this year.

At any rate, if you want to jailbreak your kindle, be sure not to update to firmware version 5.18.4 or later - you would then lose any chance of jailbreaking it, at least with currently known methods.

I should be clearer. There are no DRM-related changes in the 5.18.4.0.1 firmware and DeDRM currently still works with books downloaded using that firmware.

But what I wrote about the 5.18.4 firmware still holds. Amazon may have already implemented a DRM change in that version and if so it could be deployed in the future without a another firmware change.

Thank you. I have updated the calibre thread. It will be interesting to see if/when Amazon hardens the DRM on eink devices. Also whether Amazon will block downloads to older eink devices entirely.

The battery on my old K4BNT continues to degrade. Just wondering which will come first: the battery dying completely or Amazon blocking downloads
