WARNING: This device is not recommended for future use with postmarketOS due to its armhf architecture. Alpine Linux (the distribution that postmarketOS extends) pmaports#599 has been considering dropping it.

This device is still running on armhf, although the processor supports armv7. If you own it, change it and test it that way.

How to enter flash mode

Note that the the device gives no indication of being in fastboot mode, just a blank screen.

Also note that fastboot devices may show no permissions in place of a serial number. If this is the case, you may need to run fastboot as root. If it still shows no permissions then you probably need to install the android udev rules package, AND copy the file to /etc/udev/rules.d/ AND add the Google Glass product ID to the Google vendor ID section. The Glass has at least 9001 and 9002 as adb and fastboot product identifiers.

Method #1

enable debugging
adb reboot bootloader

Method #2

power off device
hold camera button
press power
wait 10-15 seconds

(this method is somewhat tricky since pmbootstrap devices is the only way of determining if it was successful)

Method #3

power off device
enter recovery mode
- hold camera button
- press power once
- continue holding camera button for 10 seconds
select Reboot into fastboot

Installation

Installation to flash seems to be challenging/broken at the moment, but pmbootstrap flasher boot does work to get pmOS running on the device, and you can access the device via SSH over USB networking to connect the wlan0 interface to a network using wpa_supplicant and then should be able to sudo apk add postmarketos-ui-i3wm if it didn't automatically start (which it didn't for dragon788).

Interesting notes

i3wm does work on the device, the touchpad on the temple is mapped like an absolute positioning mouse (emulates touchscreen behavior sort of). dragon788 was able to drag the i3wm initial config window to the center of the workspace, because it was way off at the far bottom right since it assumed a resolution higher than 640x360 (probably 800x600 or 1024x768 was the minimum the i3 guys expected).

SXMO doesn't show up as an option, possibly because the device is currently configured as armhf rather than arm7 so changing that per the note at the top of this page may open more options.
