h4. Installation from scratch

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).

h4. Upgrading from a previous Replicant 6.0 version

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:

* All the release of Replicant 6.0 after the 0003 have been signed with different keys than the ones before.

* The contact database has changed format due to the removal of nonfree Ambient SDK code

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:

* You will first need to prepare your device for the migration of the contact database. See the [[MigrateContactsDatabase]] article for the instructions on how to do that.

* Then once this is done, for migrating to Replicant 6.0 0004, you will need to read the [[AndroidSystemKeyMigration]] article before following the [[MinorVersionUpgrade]] installation instructions.

* Then you will need to restore your contacts. See the [[MigrateContactsDatabase]] article again for that.

h5. Galaxy Nexus and a Galaxy Tab 2 graphics

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:

<pre>

graphics.sh faster

</pre>

It will reboot and restore the previous graphic stack.

The [[Graphics#Methods-to-choose-the-software-renderer]] article also has more details on the topic.
