h1. Recovery image installation or update with Heimdall These instructions explain how to install the [[RecoveryImage|Replicant recovery image]] to your device. This procedure is part of [[ReplicantInstallation|the larger procedure of installing Replicant]]. *WARNING: these new instructions are experimental and have not been tested yet on all the supported devices mentioned below.* {{TOC}} h2. Prerequisites h3. Applicable devices This guide applies only to the following devices: * [[GalaxyS2I9100|Galaxy S 2 (I9100)]] * [[GalaxyS3I9300|Galaxy S 3 (I9300)]] * [[GalaxyS3I9305|Galaxy S 3 4G (I9305)]] * [[GalaxyNexusI9250|Galaxy Nexus (I9250)]] * [[GalaxyNoteN7000|Galaxy Note (N7000)]] * [[GalaxyNote2N7100|Galaxy Note 2 (N7100)]] * [[GalaxyTab270P31xx|Galaxy Tab 2 7.0 (P3100)]] * [[GalaxyTab270P31xx|Galaxy Tab 2 7.0 Wi-Fi (P3110)]] * [[GalaxyTab2101P51xx|Galaxy Tab 2 10.1 (P5100)]] * [[GalaxyTab2101P51xx|Galaxy Tab 2 10.1 Wi-Fi (P5110)]] * [[GalaxyNote80N51xx|Galaxy Note 8.0 (N5100)]] * [[GalaxyNote80N51xx|Galaxy Note 8.0 Wi-Fi (N5110)]] If you use these instructions with a device not listed above, there is a significant risk of ""bricking" your device":https://en.wikipedia.org/wiki/Brick_(electronics). h3. Personal computer In order to install the recovery image on your device, it is assumed that you have a computer running a GNU/Linux operating system and everything necessary to connect your device to the computer through USB. Moreover, it is assumed that anyone performing the installation knows how to use the command line in a terminal and has basic knowledge about it. h2. Install heimdall The heimdall tool is required to flash (install) the recovery image to your device. See installation instructions [[ToolsInstallation#Heimdall|here]]. h2. Download the files Find the row in the [[ReplicantImages#Images|table of images]] that corresponds to your device. Links to the recovery image and corresponding PGP signature that you must download are in that row under the column *Bootable/recovery*. Download both files to your PC. For example, if you want to install Replicant to a [[GalaxyS2I9100|Galaxy S 2 (I9100)]], you will download *recovery-i9100.img* and *recovery-i9100.img.asc*. h2. Check the signature of the recovery image First, [[ReplicantReleaseKey#Retrieving-the-Replicant-release-key|add the Replicant release key to your GPG keyring]]. Then, from the command line: # Change directories to the location of the recovery image and its signature (the location of the files may differ depending on your system setup):
cd "${HOME}/Downloads/"
# Check the signature of the recovery with the following command, substituting "" with your device's identifier:
gpg --verify recovery-.img.asc
Unless GPG reports something to the effect of a "good signature" from [[ReplicantReleaseKey#Which-key-for-which-Replicant-version|the expected key]], *do not continue*! Your downloaded files may be corrupted or compromised. h2. Prepare the device The next step in the installation process is to prepare the device for heimdall mode. # Make sure the device is completely turned off and the USB cable is disconnected from the device # Remove the device's "external case":https://en.wikipedia.org/wiki/Mobile_phone_accessories#Cases or protection if it has one. There are a few additional steps to follow, depending on which device you have. h3. Galaxy Nexus (I9250) If your device is the Galaxy Nexus (I9250): # Start the device by holding the following key combination: *Volume down, Power*. # Hold the key combination until the device shows a green "Start". h3. All other devices For all other devices: # Start the device by holding the following key combination: *Volume down, Select, Power*, # Hold the key combination until the device shows a *Warning* message. # Confirm that you want to download a custom OS using volume up # Make sure the device is in *Downloading* mode You can then connect the USB cable to both the computer and the device h2. Flash the recovery image For instructions on installing the recovery image on your device for the first time, proceed to [[RecoveryInstallationWithHeimdall#Installing-the-recovery|here]]. Otherwise, for instructions on updating the recovery image on your device, proceed to [[RecoveryInstallationWithHeimdall#Upgrading-the-recovery|here]]. h3. Install the recovery image When installing or upgrading Replicant, use the commands in the table below. This will make sure that the device is rebooted right into the recovery. It does that by also installing the recovery in the boot partition. If instead you only want to upgrade an existing recovery, use the commands in the [[RecoveryInstallationWithHeimdall#Upgrading-the-recovery|Upgrading the recovery]] section. Once in the recovery you can then proceed to the installation or s. |_. Devices |_. Command for installing the recovery image | |_. Galaxy Nexus (I9250) |

Galaxy Tab 2 10.1 Wi-Fi (P5110) | If your device reboots into the recovery OS, *you have successfully installed the Replicant recovery*. Proceed with the remaining [[ReplicantInstallation|installation instructions]], or with the [[MinorVersionUpgrade|minor version upgrade instructions]] if you are upgrading an existing Replicant installation. Otherwise, see the section on [[RecoveryInstallationWithHeimdall#Troubleshooting|troubleshooting]]. h3. Upgrade the recovery image If you only want to update the recovery, without updating or installing Replicant, use the commands in the this section. This will make sure that your Replicant installation is not modified. If instead you are installing Replicant for the first time, use the commands in the [[RecoveryInstallationWithHeimdall#Installing-the-recovery|Installing the recovery]] section. The command to update the recovery depends on which device you have. See below. h4. Galaxy Nexus (I9250) If your device is the Galaxy Nexus (I9250):
heimdall flash --recovery path/to/recovery-.img
h4. All other devices For all other devices:
heimdall flash --RECOVERY path/to/recovery-.img
h2. Troubleshooting h3. Making sure that the device is connected in download mode You can run the following command to verify if the device is in download mode:
lsusb
If it is you will then have one line that will be somewhat similar to that one:
Bus 004 Device 002: ID 04e8:685d Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II] (Download mode)
h3. Heimdall failing with "ERROR: Protocol initialisation failed!" It is pretty easy to end up with heimdall failling like that:
Heimdall v1.4.2

In that case disconnect and reconnect the USB cable from the computer and try again. If it still fails, make sure that your computer isn't doing resource intensive tasks: * Doing tasks that uses a lot your storage device (HDD, SSD, etc) can easily make the installation of the images fail. If it still fails: * Verify if your USB cable is not damaged by trying with another cable if you have one * Verify if your USB port is not damaged by trying with another port if you have one
