Plasma Phone Reference System

Supported Device: Nexus 5X (bullhead)

Needed software tools: adb, fastboot

If you flash Plasma Mobile for the first time, you likely need to follow steps 1A and 1B. After successfully done those steps, you can always jump straight to step 2 for future flashing.

1A. Unlock (skip if already unlocked)

Unlock the Nexus 5X: https://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930

1B. Put into firmware mode and run once:

CAUTION: This will erase the complete memory of your Nexus 5X device! Please ensure you have a backup of all your data before you proceed.

$ fastboot format cache 
$ fastboot format userdata

2. Flashing Plasma Mobile (PM)

Put your Nexus 5X in fastboot mode (press volume down + power button at once), then open a terminal and run

$ git clone https://github.com/plasma-phone-packaging/pm-flashtool.git
$ cd pm-flashtool
$ ./pm-flash

The -c parameter of script can be used to re-use the cache instead of downloading all the files again.

The -p platform parameter currently accepts neon, arch and edge. Edge rootfs is the latest development snapshot of Plasma Mobile and the platform recommended for testing new features and bug fixes.

It will download all files required and store them in cache subdir, e.g. for Nexus 5X (bullhead):

  • pm-rootfs-20180124-113114.tar.gz (Plasma Mobile rootfs)
  • recovery.img (TWRP recovery img)
  • system.img (Halium image containing the hardware adaption for each device)
  • boot.img (Halium initrd)

Then the TWRP Recovery img is used as a tool to flash all other components to the target device.

Note: The above could take quite some time (15-20 minutes) and require to enter your password to continue.

After Flashing is done

If successfull, you should automatically see the Login Screen. The password to unlock is ‘1234’.

(the username to enter the login prompt for your phone from an adb shell desktop terminal is ‘phablet’, password is ‘1234’).
