How to remove the "Register your Kindle" notification permanently?

[luckybeans]

I have an older Kindle Paperwhite 3 (5th), and it looks like that the system should not continue to be updated in the future. So I'm planning to use it as a single-function local e-ink reader. The problem is, I can barely get rid of the reminder to register an Amazon account.

I've tried turning off Wi-Fi to skip the setup, but the home screen still shows "Welcome to Kindle" with a "Register your Kindle" button. The most annoying part of it is when I go to the library page, it always has the pop up saying the cloud isn't available, and prompts to register the kindle.

So I decided to try jailbreaking, and I found that the final version of KPW3 firmware can be jailbroken. Is there any software plug-in that can permanently block the registration pop-up notification?

I don't know what you mean by plugin, but it is possible to convince an unregitered kindle that it is registered.

See this post:

and this thread:

It might be good to read the entire thread in case the content or format of the reginfo file have changed over time.

When jailbreaking my Kindle Paperwhite 11th edition I had plenty of time to register it, go through the prompts then immediately turn off WiFi. Then delete partial install files. Never been pestered to register since.

I have quite a few kindles registered at amazon that, except for a couple of them, are permanently in airplane mode. But my Oasis 3 was bought new at a brick and mortar store and has never been connected to wifi. I like it that way.

As to registering before an update download completes, a lot of people have had the download complete before wifi could be turned off.

Marek, you might want to change that image to an attachment or shrink it to a maximum of 600x800.

I am surprised the forum allows people to post full res images like this. It should downgrade it to 600x800 by default. Full res images should only be allowed as attachments.

It would be fantastic! I wonder if homepage layout could be tweaked to include remote webcontent either static or dynamic (weather info etc.)

You'd need to figure out how the API works and where to change the url but most of the content is pulled from there (i can't remember the name sorry) in the image above i changed the local copy of the data (it refreshes periodically)

And now we have a link that says: This content is no longer available.

What I was referring to was using the Manage Attachments or paperclip tool. While the image URL is wrapped in URL tags, that does not seem to work. Using IMG tags works but still leaves the image at it's full size.

Hi @Marek,
Do you know if thatt customization work on a kindle oasis 3 (10th gen) running firmware 5.16.2.1.1?

The way to get rid of the notification to register is to register the Kindle.
