Hi I want to unlock the write protection on my Chromebooks firmware. (I was hesitant at first but it seems like quite a professional operation using the coreboot sourcecode and is hosted very transparently on github.)

 

From what I've read my chromebook (the one I want to buy anyway, Acer Chromebook 311) has a Google Security Chip and write protection for the firmware is unlocked using the "CR50 method", which is either by removing the internal battery or using a usb-c debug cable aka suzyqcable, and running certain commands. I really would prefer not to open my brand new device the day I buy it, has anyone had any luck sourcing a usb-c debug cable from New Zealand or some other alternative?
