Please see `Paul's blog post <http://code.paulk.fr/article16/missing-proprietary-firmwares-in-android-systems>`_ for the reasons why these instructions shouldn't be published on official documentation pages of free systems, but why it still makes sense to publish them elsewhere. +The following instructions make it possible to install nonfree firmware on Android devices for the purpose of enabling certain functionalities. For now, only the Galaxy S3 (GT-I9300) and Galaxy S2 (GT-I9100) are supported, but support for other devices can be added easily. Please see `Paul's blog post <http://code.paulk.fr/article16/missing-proprietary-firmwares-in-android-systems>`_ for the reasons why these instructions shouldn't be published on official documentation pages of free systems, but why it still makes sense to publish them elsewhere. Paul's script is compatible with CyanogenMod version 10.1.3 and 9.1.0. It extracts the firmwares from a CyanogenMod installation zip and either installs them with ADB or creates an installation zip with them. My implementation is intended to be compatible with CyanogenMod 13.0. It's possible to only select a certain functionality for which the firmwares should be installed. The firmwares are downloaded from a `repository <https://github.com/TheMuppets>`_, that hosts the firmware files for CyanogenMod builds, and they are installed with ADB. It's impractical to extract them from a CyanogenMod 13.0 installation zip because recent Android versions use complicated compression techniques that require tools which are usually not readily available as packages for GNU/Linux systems. Creating installation zips is also not easy anymore because the zip needs to be signed with a key that is trusted by the recovery. If your recovery still just accepts any installation zip, then you are using an insecure recovery. |
