ReplicantInstallation¶

Installation overview¶

The installation of Replicant involves several steps:

1. Obtain a supported device
2. Backup the device
3. Install the recovery image
4. Wipe the storage volume partitions
5. Install the operating system
6. Factory reset the device
7. Reboot the device
8. Backup the modem data partition (EFS)

Obtain a supported device¶

Replicant can only be installed on one of the supported devices. Please make sure that you have the correct device model before proceeding.

The model number on your device must exactly match the model number specified on the Replicant wiki page for that device. For example, if you want to use the Galaxy S 2, you must obtain the GT-I9100 model (not SGH-I777, etc.).

Backup the device¶

Before attempting to install Replicant, you need to backup everything you can from the device as most of the data will be erased during the installation.

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

Install the recovery image¶

To install the Replicant recovery image, follow the instructions on the Recovery installation with Heimdall wiki page.

Wipe the storage volume partitions¶

Once this is done, you then need to wipe the existing system, cache and data partitions. This is to ensure that the partitions are formatted correctly.

Wipe system partition¶

To wipe the system partition, once you are in the recovery:

1. Select Advanced
2. Select Wipe system partition
3. It will ask you to confirm the wipe, so you will need to select Yes to confirm it.
4. Press the back key to get back to the general menu

Wipe cache and data partitions¶

To then wipe the cache and data partitions:

1. Select Factory reset
2. Select Wipe data (keep media)
3. It will ask you to confirm the wipe, so you will need to select Yes to confirm it.
4. Press the back key to get back to the general menu

Install the operating system¶

Installing Replicant can be done either by:

• downloading the installation files the device, without the need of a computer
• using a computer and a microSD
• using a computer and the internal storage to store the installation files

Once this is done, you will need to do a factory reset.

Factory reset the device¶

To do a Factory reset, you need to be in the recovery.

1. Select Factory reset
2. Select Wipe data (keep media)
3. It will ask you to confirm the wipe, so you will need to select Yes to confirm it.
4. Press the back key to get back to the general menu

Reboot the device¶

Once the factory reset is done, you can then reboot the device.

In the recovery:

1. Select Reboot system now to reboot the device
2. Your device now has Replicant installed!

Backup the modem data partition (EFS)¶

Some of the devices supported by Replicant have a partition that contains the modem data (called EFS).

Now that Replicant is installed, it's a good idea to do a backup of it if your device has one.

This way it would be way easier to restore it if it becomes corrupted (it can sometimes happen with Replicant).

For a list of devices that have a modem data partition, and for instructions on how to do a backup of it, see the BackupTheEFS wiki page.
