thanks for the write up! do you know where the bluetooth is on the motherboard? I presume step 10 are the connections to the wifi antennae?

This Chromebook likely uses a dual chip which can be seen in step 10. I’m guessing the chip is a 802.11AC 2x2 MIMO WLAN + Bluetooth 4.0 from looking at the specs.

wich is the firmware write protect screw on the motherboard to cheng the os to win10 ??

loudikov - Contestar

This is an ARM MT8173 machine, no Windows 10 for this hardware… Win10 for ARM is still on ARM based Surface, and gives poor experience.
