Codexctl

A utility program that helps to manage the remarkable device version utilizing ddvks update server

PLEASE READ BEFORE USING

If your remarkable device is at version >= 3.11, codexctl will not be able to automatically install updates on it due to a major overhaul in the update engine. You can still use the other functions like downloading the image files and then manually extracting it, using dd to write to the other partition and then using the restore command. More information can be found in https://github.com/Jayy001/codexctl/issues/71#issuecomment-2099115757.

Installation & Use

You can find pre-compiled binaries on the releases page. This includes a build for the reMarkable itself, as well as well as builds for linux, macOS, and Windows. It currently only has support for command line interfaces but a graphical interface is soon to come.

Usage

The script is designed to have as little interactivity as possible, meaning arguments are directly taken from the command to run the script.

codexctl list # Lists all available versions 
codexctl restore # Restores previous version
codexctl --verbose # Enables logging
codexctl --backup # Exports all files to local directory
codexctl --backup -l root -r FM --no-recursion --no-overwrite # Exports all files from FM directory to root folder on localhost
