How to Copy Files to the Internal Folder on Recent Kindle Models

[beecom]

I am using a Kindle Scribe(2022) and a Kindle Paperwhite5(11th gen), and both are jailbroken with WinterBreak. The current firmware version is 5.16.9, and I plan to update to 5.17.1.

What I want to do is overwrite the code2000.ttf file in the Kindle's usr/java/lib/fonts folder with another font file by renaming it. The reason I want to do this is that when using WordWise, the font for showing Korean hints in firmware 5.17.1 has become hard to read, and I discovered that this is due to the code2000 font.

I confirmed the location of this file using KOReader's file browser, but copying the file with KOReader is impossible. Maybe due to a permissions issue.

What method can I use to make this possible? It seems that people used usbnetwork to copy files to the Kindle's internal folder in the past, but all the relevant guides are for older Kindle models, so I’m not sure how to apply it to the recent Kindle models.

That part of filesystem is mounted as "ro" (read only). You need to use Terminal Emulator to remount it as "rw" (read & write) using this command:

mntroot rw

IIRC those fonts are all inside a squashfs image and that image gets mounted into that fonts folder.
So you would have to replace the whole squash img...

Thank you for your comment, shamanNS. To connect to my Kindle using a terminal emulator like PuTTY, I need to enable USBNetwork on the device, right? How can I enable USBNetwork on my Kindle Scribe, which I jailbroke using WinterBreak?

I also found that on a Windows PC, I can use squashfs-tools-ng to create .sqsh images. I'll give it a try.

I could connect to my Kindle using usbnetlite.

But I couldn't replace fonts.sqsh file with my edited one because it was in mounted state.
