Google Nexus 5 (lg-hammerhead)
First make sure to enable USB debugging in Android () Then with device powered off, hold down and buttons simultaneously for a few seconds, until Fastboot Mode screen appears.
Get device into Fastboot Mode, plug in USB cable, then:
$ sudo fastboot oem unlock
When prompted on device, use Volume-Up/Down buttons to highlight choice, then Power button to select it. The Fastboot Mode screen will appear again, and a message regarding flashing will appear briefly.
First build the image:
$ git clone https://gitlab.com/postmarketOS/pmbootstrap $ cd pmbootstrap/ $ ./pmbootstrap.py init $ ./pmbootstrap.py install --no-fde
Then in order to flash it put your device in fastboot mode, and plug it in USB. Then do:
$ ./pmbootstrap.py flasher flash_rootfs --partition userdata $ sudo fastboot format system $ ./pmbootstrap.py flasher flash_kernel
WiFi workaround on boot
The wifi adapter works in NetworkManager, but it boots in airplane mode and NetworkManager does not detect that. Therefore at boot you need to disable the wifi adapter first, and then re-enable it. This can easily be done in the graphic shell (Plasma Mobile has an airplane mode switch in the pull-down menu: check it and uncheck it) or through the shell:
$ nmcli radio all off $ nmcli radio all on
Fastboot unknown chunk type
Flashing with fastboot seems to fail for some outdated firmware, it prints the message "FAILED (remote: Unknown chunk type)" when trying to flash the rootfs to userdata. This can be solved by updating to the latest baseband firmware and bootloader.
