Looks like the PW5 is stuck on the awful 5.19.2 unless you're lucky enough to to be on an earlier firmware in airplane mode.

I still have my Kindle Scribe 2022 version on 5.18.6. Apart from sideloaded pdf annotations, is there a reason to upgrade? Is this reasonably safe now or is it a vibe-coded mess?

I would stick with what you have in airplane mode. There's not enough information on this new firmware.

Initial reports from KCC users for sideloaded manga/comics:

Some people were reporting the same issues as 5.19.3: all the options in the Aa menu are gone like virtual panel view, 2 page landscape had pages on wrong side, no % read.

But some people decided to update to 5.19.3.0.1 via usb while the Kindle was in airplane mode. 4 reports saying that all the problems were gone.

Then one person tried turning wifi on and all the problems returned.

Copy pasting the discussion from last thread, hopefully this issue is fixed, I think I saw some reddit commenters saying it was fixed but we will have to see.

I think someone found the real reason 5.19.3 got pulled (this bug may have been activated for only some users on 5.19.2 and all users on 5.19.3). Sounds like the Kindle is continously uploading gigabytes of logs for 15 hours at a time to Amazon servers in sleep mode. And nothing, even a factory reset, helps.

One comment sums it up in a funny way (though it was only 3 GB over 17 hours):

effectively the [kindle update] created a botnet DDoSing Amazon

Based on the reddit thread, the error logs are related to errors from upload attempts, so they wouldn't be generated in airplane mode. And the logs only exist briefly in ram so don't affect free space. Basically logs are continuously being generated and deleted rapidly in ram and uploading at the same time.
