You can skip this step if you have no data you want to keep.

The installation of Replicant is several steps:
12
* First you install a Replicant recovery. It's a very minimalist operating system that is dedicated to the installation of Replicant.
13
* Then you download Replicant and use the recovery to install it.

Once this is done, you then need to wipe the existing system partition. This is to ensure that the system partition is formatted correctly.
22
23
To do that, once you are in the recovery:
24
1. Select Advanced
25
2. Select Wipe system partition
26
3. It will ask you to confirm the wipe, so you will need to select Yes to confirm it.

h2. Backup the EFS
56
57
Now that Replicant is installed, it's a good idea to do a backup of the EFS partition which has the modem data.
58
59
Only the following devices that are supported by Replicant have an EFS:
60
* Galaxy S 2 (I9100)
61
* Galaxy S 3 (I9300)
62
* Galaxy S 3 4G (I9305)
63
* Galaxy Nexus (I9250)
64
* Galaxy Note (N7000)
65
* Galaxy Note 2 (N7100)
66
* Galaxy Tab 2 7.0 (P3100)
67
* Galaxy Tab 2 10.1 (P5100)
68
* Galaxy Note 8.0 (N5100)

First make sure that you have adb setup correctly and that it gives you a root shell on the device by following the wiki page that explains how to [[ADB|install adb and get a root shell]] on your device.
71
72
Once this is done you can then backup the EFS.
73
74
For the Galaxy SIII (I9300), run the following commands to do that:
75
<pre>
76
mkdir backup_efs
77 8 Denis 'GNUtoo' Carikli
cd backup_efs
78 7 Denis 'GNUtoo' Carikli
adb pull /efs/ efs
79
adb shell "cat /dev/block/platform/*/by-name/EFS" > EFS.img 
80
</pre>
81
82
This will create a copy of the contents of /efs in the backup_efs directory. It will also backup the full partition.
83
Keep these files around as a backup in case anything goes wrong.
