Email from Amazon:

Starting May 20, 2026 we are discontinuing support for Kindle devices released in 2012 or earlier.

Affected devices include Kindle 1st and 2nd Generation, Kindle DX and DX Graphite, Kindle Keyboard, Kindle 4, Kindle Touch, Kindle 5, and Kindle Paperwhite 1st Generation.

Why? My 1st Gen device is working perfectly. They are creating eWaste.

@NormanDunbar you can install koreader on, at least, some of them.
@arpia49 Not on my first generation Kindle. Sadly.
@NormanDunbar oh! Sorry for the usefulness of the recommendation. I've keep my old Paperwhite for long but FOR SURE, my next e-reader (if any) won't be Amazon.

@arpia49 Hey, no worries. You tried. My equipment let us down. 😉

Cheers.
