- via Settings->Update, the update works, because pubdevkey01.pem is considered.
- just putting it there and restarting does not work, because pubdevkey01.pem does not seem to be considered. Constantly getting Update error 3 here.
At least this is the current state of affairs on my device. I may also have screwed up something somewhere... (I thought that update*.bin had previously worked here as well with just restarting).
Can anyone clarify on this (i.e. how their device behaves for these two cases, with the mp3 jailbreak first, and then with the tar one)?
Unfortunately, the updates that run on restart are of another type (see option "kindletool create recovery"). The key for that is embedded inside the kernel (initramfs to be specific). In short, nope. Your bug also works on kindle 4s, so it would be nice if we get it working on there too. You can't use the dev key method, but you can use my key binding method from the 3.2.1 jailbreak. If you don't have the time, I can do it for you.
