== OpenPGP Smartcard ==
In order to use the OpenPGP smartcard reader, most Librem 5 phones will need to have the reader firmware upgraded. The firmware can be built from source, but Purism has created a helper script to download/flash the firmware. In order to run this script on Alpine Linux / postmarketOS, these patches should be applied: https://source.puri.sm/angus.ainslie/ttxs-firmware/-/merge_requests/3/diffs
Running the script should result in the following if it is successful:

Installation

From pre-built image (easy method)

Official images of postmarketOS for the Librem 5 are built at least every week. Currently the device is only supported on the edge branch of postmarketOS.

This method requires the uuu application is installed on the host computer. <uuu> is NXP's image deploy tool, and may be found in some distros in a package named mfgtools.

Download the right image

  • Branch (more):
    • edge: bleeding edge version (has latest features, but may break more often).
  • User interface
    • Phosh: Purism's GTK based phone interface (more)
    • Plasma Mobile: KDE's Plasma based phone interface (more)
    • (Note that more interfaces are available, build your own image with pmbootstrap if interested)
  • Pick the latest image by its date
  • Choose the regular image, or the installer image
    • Graphical Installer:
      • Ends in -installer.img.xz
      • Recommended for a proper installation.
      • Encrypting your installation is possible
      • Passwords for user and SSH are set during installation (and SSH can be disabled)
    • Regular image:
      • Ends in .img.xz
      • An installation of postmarketOS with defaults for passwords and no full disk encryption
      • The login is user with password 147147
      • sshd is currently enabled by default! (build.postmarketos.org#85)
      • Not recommended, unless looking for a quick way to try out postmarketOS

Download JumpDrive

Grab the latest purism-librem5.tar.xz image from the JumpDrive release page

Note JumpDrive 0.7 is the first version to support the Librem 5

Extract it, and you should see something similar:

$ tar xf purism-librem5.tar.xz
$ ls
boot-purism-librem5.sh  dtbs  initramfs-purism-librem5.gz  kernel-librem5.gz  purism-librem5.lst  purism-librem5.tar.xz  u-boot-librem5.bin

Run JumpDrive

Place the Librem 5 into #Flash Mode.

Use the helper script from the JumpDrive release to flash the Librem 5:

$ ./boot-purism-librem5.sh
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.72-0-g8e9e189

Success 1    Failure 0

3:2     10/10 [Done                                  ] FB: Done

Flash to EMMC

In order to flash the postmarketOS image to the Librem 5, locate the bock device exposed to the host computer via JumpDrive:

$ lsblk -o name,size,model,vendor
NAME        SIZE MODEL                     VENDOR
sda       476.9G Samsung_SSD_860_PRO_512GB ATA
├─sda1   1007.5K
├─sda2    476.8G
│ └─root  476.8G
└─sda3     99.3M
sdc        29.1G e_eMMC                    JumpDriv
├─sdc1      189M
└─sdc2     28.9G
zram0       247M

In the example above, the /dev/sdc is the EMMC device on the Librem 5.

Warning WARNING: Triple check you have selected the right block device when performing the next step!!
$ xzcat 20210217-0609-postmarketOS-edge-phosh-6-purism-librem5-installer.img.xz | sudo dd of=/dev/DRIVE status=progress bs=1M oflag=direct iflag=fullblock

4291821568 bytes (4.3 GB, 4.0 GiB) copied, 200.427 s, 21.4 MB/s

Remove the usb cable and power cycle the phone to boot into the postmarketOS installer.

With pmbootstrap (Advanced)

Use pmbootstrap to build a customized image. Consult the installation guide for details.

$ pmbootstrap init # vendor: purism, device: librem5
$ pmbootstrap install...  # add --fde for full disk encryption

Place the device into #Flash Mode, then flash it with:

$ pmbootstrap flasher flash_rootfs

Flash Mode

To place the Librem 5 info flashing mode, perform the following:

  1. Ensure that the phone is switched off.
  2. Turn all Hardware-Kill-Switches off
  3. Remove battery
  4. Hold volume-up
  5. Insert the USB-c cable: (red light blinks, no green light)
  6. Reinsert the battery: (red light is constantly on, the script will continue)
  7. Release volume-up
Note Some USB-C cables may need to be plugged into the phone with a particular orientation. If the instructions above do not appear to work, try flipping the USB-C end of the cable over and replugging it into the phone.

These directions were gathered from Purism's documentation, refer to it for additional details/troubleshooting.
