I just downloaded mrchromebox’s software on a new jasper chromebook. Was not able to remove WP due to the Jasper models being limited but now that I am able to boot my own OS alongside Chrome OS, I am having some difficulties.
For starters, I am trying to boot an Arc Linux IOS through a flash into the chromebook but it simply gives a multitude of errors. For starters I get the "/syslinux/vmlinuz.B not found " error and then also the “hd0,3 not found” when specifically tryna boot from my flashed usb.
I did some digging online and spent time messing with grub before attempting boot through the USB again but still to no avail, figured I would ask yall how I can actually get to booting arc and using any OS other than chrome on this guy.
Sorry for the delay in my response as well. Let me know if any of this is helpful or if you’ve tried it already.
Looking up your model, it looks like it uses CR50 for write protect.
According to MrChromeBox’s docs, if you undo the bottom panel and disconnect the battery you should be able to remove write protect.
Using my C13 Yoga Chromebook as an example:
Unscrew bottom metal panel
Gently pull battery cable from the connector to disconnect it
