I confirm, spent all day fighting brand new Scribe, but was able to install Koreader on it.

To get to the search "command line" on the main screen:

1. Set up my wifi router to limit connection speed to 500Kbps (I tried a range from 20 to 300Kbps, that did not work, Kindle considered connection broken)
2. Registered Scribe into my acount
3. Once it loaded to the main screen with search box, turned on Airplane mode.
4. Connected via USB and deleted partial update (somethign like update.bin.partial file). It got to 30MB max in all my tries, so plenty of time to stop it before it fully downloads (total size ~270-320MB)

What did not work:

1. blocking softwareupdate.amazon.com via pi-hole. Scribe complained about not being able to download an update without any option to skip it.
2. using some empty file to prevent scribe from checking internet connection (like INTERNET_NO_PROBE or something)
3. Trying to find a way to skip wifi connection or using wifi without internet access

Scribe was shipped with 15.6.0, initially it tried to update itself to 15.6.1(filename of the update Scribe started to download was update-3900690052-{some hash}.bin and even fully downloaded the update when I forgot to turn off it's access (started to download right after first wifi connection, even before registration).

I then manually updated it to 15.6.1 which I downloaded and then to 15.6.2 (probably the second update was not necessary, I did it only after a few messed up tries to JB on 15.6.1.)

My whole process was:

1. Update Scribe to 15.6.2
2. Register Scribe before it fully downloads the update
3. Delete partial update after turning on Airplane mode
4. Do LanguageBreak
5. Do LanguageBreak hotfix (after that I was out of managed mode, so I did not do post hotfix manipulation such as going into demo mode again and reselling)
6. Do NiLuJe's JailBreak-1.16.N-FW-5.x-hotfix.zip
7. Do kual-mrinstaller-1.7.N-r19303.tar.xz
8. Do KUAL-5b5d1d2-20231104.tar.xz (coplate)
9. Install Koreader
