How to install

With a recent u-boot (including that shipped by current Mobian images) the librem5 is able to boot from SD card. To do this, hold the Volume-Down button while powering the device on.

To install Mobian to the eMMC there are 2 options, both requiring that you install NXP's uuu utility. On Debian systems, you can simply apt install uuu.

Alternatively (e.g. if your distribution doesn't package uuu), you can download the latest release from Github (you can either build from source, or directly download the uuu binary for Linux/x86_64).

Using Jumpdrive (preferred)

Jumpdrive is a minimal system exposing the device's storages (eMMC and SD card, if any) as USB mass storage devices. Download the latest release Jumpdrive available for the Librem 5 (purism-librem5.tar.xz), uncompress the archive and cdinto it.

Then put your Librem 5 in USB download mode by following the instructions provided by Purism, and execute:


Your Librem 5's eMMC should now appear as a USB drive on your computer and can be flashed using bmaptool, dd or Etcher the usual way.

Using Purism scripts

First, download the librem5-devkit-tools repo:

git clone

Then, navigate to the librem5-devkit-tools directory, and create a mobian sub-folder containing the (uncompressed) Mobian image, renaming it librem5r4.img.

Next, download the latest u-boot-librem5.imx file from Purism's CI, and move it to the mobian folder too.

Finally, put your Librem 5 in USB download mode by following the instructions provided by Purism, and execute the following command:

./scripts/flash-image --board librem5r4 --dir mobian

(Replace librem5r4 with librem5r3 if you have an Dogwood Librem 5, librem5r2 if you have an Aspen/Birch/Chestnut, or devkit if you have the Librem 5 development kit)
