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:

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.
