PW5 Recommended older firmware to downgrade to?

laki · Yesterday, 04:59 PM

I jailbroke my Kindle Paperwhite 5 (11th gen) a few weeks ago, and while I still prefer the native Amazon experience (reading purchased books and having them synced via whispersync), I'm looking to downgrade the firmware as I feel my Kindle used to be much snappier originally.

Is there a "best" recommended older firmware version that could check my performance preference and still be working well in 2026?

Claude recommended either 5.14.2 (Jan 2022, before library redesign) or 5.16.5 (Nov 2023, after introducing Goodreads sync, which I use), but I'd appreciate real users' experience.

If you are on 5.18.x or above there is boot loader hardening so you cannot downgrade.

Oh. I’m using 5.19.2 actually. Does it mean I can’t downgrade at all, or only to 5.18.x but not earlier?

Yeah, you cannot

Well, at least I didn’t discover this by failing to downgrade myself. Thanks.
