ExtremeROM Nexus is a work-in-progress custom firmware for Samsung Galaxy devices.
ExtremeROM Nexus is a work-in-progress custom firmware for Samsung Galaxy devices. It's based on the latest and greatest iteration of Samsung's UX and it also includes additional featur 8000 es and tweaks to ensure the best possible experience out of the box. It is based on the UN1CA build system which allows automatic downloading/extraction of the firmware, applying the required patches and generating a flashable zip/tar package for the specified target device. ExtremeROM Nexus supports devices using the Exynos 9820, Exynos 990 and Exynos 2100 SoCs
Any form of contribution, suggestions, bug report or feature request for the project will be welcome.
