Hello! I just bought a jailbroken Kindle Oasis 3 (FW 5.14.2) from someone on here MobileReads (thanks lexic!), and I have a couple of questions:

1. I tried to install the latest version of KOReader (2023.03, the "PW2" version, following instructions from https://github.com/koreader/koreader...Kindle-devices), and I have unzipped into the root directory of my Kindle (so there is both a /koreader and a /extensions/koreader directory), and I can see it in my KUAL booklet, but whenever I try to run it, KUAL just closes, and the whole screen flashes once, and then nothing happens afterwards. Tried the "no framework" and "ASAP" versions, and I don't even get the flashing - KUAL closes and nothing happens. I did see some logs in /koreader/crash:

It's a scroll... It's a codex... It's KOReader!

Has anyone seen this before?

2. I'm not sure I understand how KUAL is supposed to work. Whenever I press on some item in the menu (e.g. KUAL -> "Rename OTA binaries" -> "Rename"), KUAL just closes. Does that mean... it did anything? Same thing if I put some .bin into the /mrpackages directory and go to KUAL -> Helper+ -> Install MR Packages, it just takes me back to the Oasis home screen and nothing happens. This isn't the case for all menu items though (KUAL -> Helper+ -> SHOW Network Info DOES show network info after quitting to the home screen), so I'm quite confused on how this is supposed to work.

Thank you all so much!
