Current JB has preventative mechanism to stay alive.
However, you can still kill it for good if you do two firmware updates in a row, or two factory resets in a row, or any combination of these two. If by the end of these two operations you end up on 5.16.3 and above, game’s over (hntil next JB method releases) |

The file you are looking for is called fixup. It lives in /var/local/system/ after JB

The essential effect of the jailbreak process is to get a community developer key into /etc/uks, which can only be done by exploiting some vulnerability. Over time, functionality was added to squirrel away the ability to restore the developer key during a restart (reboot) after a firmware update or a reset. If an update is followed by a reset without a restart, or vice versa, bye bye jailbreak. The developer key is needed because only packages signed by a key in /etc/uks can be installed. Of course, once USBnetworking or a terminal emulator is installed, / can be mounted rw long enough to put anything you want anywhere you want. |

If with ads, can you use the book covers as wallpaper in Koreader after jailbreak? |

You can, but you need to add an "user patch" that overrides the default KOReader behavior.

It was with ads. Just tried it. Yes, book covers show up when I suspend from Koreader. I use a nightly version if that makes a difference. I don’t remember installing any patches.

Probably a very stupid question, but once you have 5.16.2 jailbroken, do most tinkerers then attempt to jailbreak 5.16.3 or would they jump to, say, 5.16.10?
I have friends who bought new Kindles and I couldn't warn them of these jailbreak things before (I said buy a Kobo but here we are) and now I'm researching on their behalf how to get them on KOReader haha. |

Also, as a general rule, hacks like this tend to work only on a lower firmware than the latest one; the reason for this is that many hackers choose to give a heads up to the vendor before releasing the exploit, giving them a chance to patch it before the exploit becomes public. I'm not familiar enough with the release timeline of previous Kindle jailbreaks to tell whether it's historically been the case for the Kindle, but it's often like this on other platforms. If your friends are interested in jailbreaking their device, they should stay on whatever firmware they are on now, by keeping the device in airplane mode; with some luck, it will be supported by any new jailbreak method coming out. |
