I just wanted to report that everything has worked well for me. I'm running a PW5 with working Koreader. These are the steps that I have followed:

0. I have performed all the steps in the airplane mode to give Amazon 0 chances to push a firmware update at me.
1. Updated my firmware from 5.14.3 to 5.16.2.1.1 and switched the device language to English (just in case)
2. Performed the steps in the main post to install the jailbreak. Everything has worked as expected. Somehow my device was still in English after installing the jailbreak, but I have installed the hotfix anyway.
3. I have installed MRPI and the "extensions" folder from the zip that was linked in this thread
4. Then I have installed KUAL and renameotabin extension
5. After verifying that everything works, I have changed a password on my hotspot, connected my Kindle and logged into an Amazon account (to get rid of stupid "cloud not available" popup). Once the device has logged in, I have disabled the hotspot, enabled the airplane mode and changed the hotspot password again, in case my device wanted to try something funny.
6. Installed the latest version of Koreader.
7. Connected to my home WiFi for a brief moment. After the Kindle appeared in my router GUI, I have banned it from accessing the internet, while allowing it to access the local network.
8. Verified that I can connect to my Calibre server and to my calibre-web OPDS catalog on my local NAS, but can't access any external resources.
9. Changed my device's language back to Dutch.


I'm very happy with my device now and I'm very grateful to everyone who has made this jailbreak possible.

On my device Kual returns me to the homepage when i start Koreader. Have you encountered that problem?

@Marek i could use your help. Please!

Which version are you using? Try nightly 10-1 from here (take the one that has PW2 in the name for Kindle): http://build.koreader.rocks/download/nightly/
What is your device and FW?

[mergen3107]

Most importantly, please go to koreader folder on Kindle via PC, then bring here the crash.log file, it has details of why it didn’t like something.

If it says “cannot refer framebuffer” or something like this, then your JB wasn’t complete. Try multiple restarts and reinstall hotxies and do restarts again.

@QBit99:

Spoiler alert: you do not, in fact, possess a PW4 as your info box suggests . That was a KT5.

[QBit99]

It's been added recently

[mergen3107]

No, not yet. The linked PR that NiLuJe gave you hasn’t been merged yet (it’s color on GitHub will turn purple). And only then we need to wait more until new nightly is rolled out.

Nightly will have at least 10-3 in the name.

Does not work for me. I am in 5.16.2.1.1. After resell and extracting again the tarball in the root of the Kindle, the light stays ambar in the Power On screen. I force start and I don't get the pseudo language. Starting with Chinese does not do anything.
