If you are installing Replicant 6.0 0004 from scratch you can simply follow the usual ReplicantInstallation instructions.
You can also follow the ReplicantInstallation instructions if erasing your data in the process is not an issue or if you are upgrading from Replicant 4.2 (as nobody wrote instructions to upgrade from Replicant 4.2 while keeping the data).
Upgrading from a previous Replicant 6.0 version like Replicant 6.0 0003 Replicant 6.0 0004 requires a special procedure to do a data migration.
This is because because:If for some reasons you don't care about keeping your data, or that for some reasons these procedure fails and that you don't care about your data, you can simply follow ReplicantInstallation.
To upgrade from Replicant 6.0 0003:Due to a bug with the integration of a new, more compatible graphic stack based on llvmpipe, once booted, the Galaxy Nexus and a Galaxy Tab 2 graphics are extremely slow.
So if you have a Galaxy Nexus (GT-I9250), a Galaxy Tab 2 (GT-P3100, GT-P3110, GT-P3113, GT-P5100, or GT-P5110 ) you might also want to restore the previous graphics stack.
To do that, you can follow the EnablingRootAccess article to get root access on the device, and run the following command on the device:
graphics.sh faster
It will reboot and restore the previous graphic stack.
The Graphics article also has more details on the topic.
