Hello, i want to try out KOReader on a Kindle Keyboard I have, and I tried following this YouTube guide on how to jailbreak it and install KOReader.

I followed all the instructions exactly, but when i try to open KUAL, it simply tells me "Mobileread Kindlet Kit is not installed." However, I installed the B008 mkk and made sure to update the kindle afterwards, even doing it twice.

Also, if it helps, i'm on version 3.4.2

Even a factory reset doesn't help. Can anyone please help me to get this working? I would really appreciate it.
