> Hardware Preparation
> Open the case
> You'll now have to disassemble your device (which most
> likely voids your warranty).
> Disable write protect
> You'll have to locate the Write Protect jumper and enable it.
> This will make the BIOS read-write so you can update it.
> Once things have been updated, you can undo this so your
> BIOS is read-only again.
> Reassemble the device
> Now that you've done toggled the jumper, you need to
> reassemble the device and power it up.
> Check the write protect
> Run crossystem and look at the wpsw_cur field; it should be 0.
> Plug your system in to be safe!
> For the Chromebook laptop, make sure the battery is charged,
> and the power supply is connected.
> For the Chromebox, try and plug it into a battery backup
> (UPS), and don't try this during a storm :).
> for location of jumper
Stumpy / Lumpy had a jumper. On the Pixel it's a screw next to the USB
