I recently received a number of these Asus Chromebook 100P laptops as a donation. They're cute little laptops, but are on an expired version of ChromeOS, and since they're #arm I can't use my usual tricks with MrChromebox.

Well @cinimodev apparently is way smarter than me, and figured out how to get #postmarketOS running on this in no time.

He even wrote it up. Check it out. It's brilliant. Yay, #linux

@codemonkeymike @cinimodev

yikes that's some effort!

@stefani @codemonkeymike I could get it down to under 15 min install it it wasn't for that write protection screw 😂

@cinimodev is it maybe compatible with a SuziQ dev cable? Or too old for that. The unlock process is getting worse and worse over time. Fucking Google.

IIRC the original chromebook was an external WP screw.

@BigHeadMode Honestly, the screw isn't that bad. The hard part is popping the catches off on the body and then removing the ribbon cables for the keyboard and touchpad so I can lift away the body. Getting those cables back installed is a PITA.

@BigHeadMode @cinimodev
That cable talks to the GSC/Cr50 (from what I remember Cr50 is just the firmware name) chip, so if it has a write protect screw, that’s not present, the screw controls the write protect status instead, so you’ll need to remove the write protect screw to get at the AP firmware

Also I doubt you’ll need to remove the firmware write protect screw for postmarketOS, given it builds a boot image compatible with the stock firmware and bootloader

@ishaderdevicemgr @BigHeadMode Normally I wouldn't bother. But, I wanted to write some new GBB flags so the dev mode screen is shorter and no beep.
