Haier Chromebook 11: open firmware (coreboot)

Supported by coreboot (src/mainboard/google/veyron). Flash: SPI, soldered. flashrom: yes.

Get started

One known way to put open firmware or software on this device, easiest first. Each one links to the project's own instructions.

Before you start

Back up your data and settings (and the stock firmware, when the guide says how).
Check the exact model, hardware revision and firmware version against the guide: a close model may not work.
Charge the battery or use a stable power supply; do not unplug during the install.

Install coreboot

Hard

Opening, soldering or a programmer · coreboot

You need: flashrom, SPI flash programmer (CH341A) to recover from a failed flash
Device opened: No
Brick risk: High
Reversible: Yes

Chromebooks already ship coreboot-based firmware; flashing your own build needs the firmware write protection disabled first (a screw, the battery or a debug cable, depending on the model). There are no official images: you build coreboot for this board from source (some boards need vendor binaries extracted from the stock firmware). Back up the original flash contents first: writing them back with a programmer restores the stock firmware.
