h2. Replicant Status

The device has a modem that is not isolated. Because of that, the Replicant project isn't interested in officially supporting that device anymore until that issue is fixed.

More details on the issue and how to potentially fix it are available in the [[Exynos3110ModemIsolation]] wiki page.

However even if that issue isn't fixed or can't be fixed, the Replicant project still wants to collaborate with other projects or people wanting to add support for it in various other projects.

To make it easier for other projects to support that device, Replicant can still try to make sure that libsamsung-ipc and libsamsung-ril work for that device.

It's also still possible to build Replicant 4.2, which support this device with a recent libsamsung-ipc and libsamsung-ril.

To do that you need to install Trisquel 7, which is not supported anymore by Trisquel.

It's possible to do that from within Parabola with debootstrap and run the resulting rootfs in lxc through libvirt.
