Koreader crash on start Kindle Paperwhite 7th gen - G090 - Firmware V. 5.16.2.1.1

[stimulant-easefu]

Hello, Koreader is crashing on startup for me with the latest nightly builds either from marek or from the koreader project. I got this Kindle already unlocked from someone else but they had issues installing koreader as well. I tried a couple different versions of koreader to see if any worked, but none did. The screen flashes a bit but then goes back to home screen.

Legacy, Kindle, and PW2 packages had logs that looked like this:

crash from PW2 version:

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

The only difference in the crash between PW2 and Legacy and Kindle versions is the endline. For kindle version it becomes [C]: at 0x00013e81, for Legacy it becomes [C]: at 0x00014f4c.

For crashes for HF/Marek versions, I get:

 /var/tmp/koreader.sh: line 323: ./reader.lua: not found

On both.

Any help or pointers would be appreciated.

Framebuffer error means you didn’t do JB properly.
Do two simple restarts in a row, then install latest hotfix from NiLuJe’s snapshots.

Yours is 5.16.2, so use normal kindle-pw2

I'm supposed to use the hotfix in this thread? For the kindle 5? I'm a bit confused by the generation numbers, this is a 7th gen kindle paperwhite. https://www.mobileread.com/forums/sh...d.php?t=225030 https://storage.gra.cloud.ovh.net/v1...5.x-hotfix.zip

I've been told that this was jailbreaked with marek's languagebreak

Yes, see “Packages targeting the Kindle 5” - JB Hotfix
