Hi all, been following mrchromebox guide on how to install windows on a Chromebook, I’ve got a Gallop board type which is supposedly a supported device, I’ve gotten to the point where I need to disable the write protection of the Chromebook however it seems to be a jumper protected wp and I’m not quite sure how to go about both locating and bridging the jumper, would appreciate any help.

It seems people who have tried, cannot locate the jumper (check this thread: Write protection jumper on an Asus CX1700CK)
I have the same model as you (Asus CX1700) and ended up buying the debugging cable/circuit board on Ebay and unlocking the firmware that way. The process of unlocking the firmware with this cable (they call it a SuzyQ cable, idk why) is considerably more involved then simply shorting a jumper.
I’m available to help if you end up trying it yourself.
I had success after much persistence in unlocking the firmware, flashing with the Mrchromebox (UEFI) Full ROM, and installing Debian linux and Windows 11 on the machine (I ended up ditching Windows but wanted to install as a PoC, turns out the touchpad was non-working in Windows).
Here’s the Ebay link (as far as I know this is the only place you can buy a prefabricated Chromebook debugging circuit board, otherwise you’d have to breadboard the entire circuit yourself): GSC Debug Board (aka "Chromebook Debug Cable" / "SuzyQ", for Cr50 / Ti50) | eBay

Old post, but I just happened to come across this, browsing posts about the CX1700 (which I have). There is no jumper. You have to remove the battery cable from the motherboard and boot from external power to disable write protection. After that you can put the cable back and WP stays disabled.
You must remove the cable from the motherboard. Disconnecting it from the battery end is not sufficient.
Hope this helps somebody in the future. This model makes a great Fedora machine.
