KT2 So what can I do about KUAL?

nicnic2001 · 05-04-2020, 02:53 AM

Well, hello. I haven't touched my Kindle JB in about four years. However, stupidly, I updated from around version 5.6.0 to 5.12.1 a while ago. On a sleepless night I decided to mess around with my Kindle. I found out that KUAL will not start: "Application Error". So I did some research and ran an emergency.sh script which worked, ended up with three files and restored ;log. So I immediately installed the JB hotfix through ;log mrpi and my kindle restarted.

So now back to KUAL. I have placed the .azw file in /documents and I have tried installing the coplate hotfix through ;log mrpi, which did not work. When I place the hotfix in the root of my kindle to try through UYK, I just get an error saying I've placed an invalid update files etc.

What should/can I try?

Interestingly I found this in MRPI logs

Okay so after finding out the hotfix is installed via UYK and the bridge is installed via MRPI, I managed to get the hotfix installed.

After installing the KUAl installer (not hotfix), it works!

What should I do now? Perhaps install bridge? Also, can I update my kindle?

Reading the documentation would be a good start.

The hotfix *is* the bridge.

FW 5.12.x is evil.

That should answer both your questions.

Thanks. I did the update anyway, confident that the bridge would survive and it did. After reinstalling KUAL hot fix, everything was working perfectly!
