Installation

Download the latest image for your device here

PinePhone / PineTab

Then use dd to flash the image to an SD card. Jumpdrive is pretty small, so there is no need for a large storage SD card.

Insert the SD card to the device, then boot it up, you should get a nice splash screen and you should see a new storage device after you plug the device to USB.

With the device plugged in, you can now flash a distro, or fix a unbootable installation.

WARNING: In case eMMC isn't showing up try to charge your battery and try again. There are reports of people not being able to flash to eMMC with discharged battery.

Librem 5

Extract the downloaded JumpDrive release archive for the Librem 5, put the device into flash mode, then run the boot-purism-librem5.sh script from the release.
