Codexctl

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

Caveat for downgrading from 3.11.2.5 or greater to a version less than 3.11.2.5

If your reMarkable device is at or above 3.11.2.5 and you want to downgrade to a version below 3.11.2.5, codexctl cannot do this currently. Please refer to https://github.com/Jayy001/codexctl/issues/95#issuecomment-2305529048 for manual instructions.

Paper Pro bootloader updates

When downgrading a Paper Pro device across the 3.20/3.22 firmware boundary, codexctl automatically handles bootloader updates. It will download the current version's firmware if needed and extract the necessary bootloader files (update-bootloader.sh and imx-boot) to ensure a safe downgrade.

Installation

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. Alternatively, you can install directly from pypi with pip install codexctl. Codexctl currently only has support for a command line interfaces but a graphical interface is soon to come.

Finally, if you want to build it yourself, you can run make executable which requires python 3.11 or newer, python-venv and pip. Linux also requires libfuse-dev.
