Hi Matt,
Firstly apologies, I've tried everything I think of to sort the issue but I just haven't had any joy.
I followed the instruction in the original post, I made sure I followed the Device Prep section, downloaded & ran the script no problem.
I was then able to install the Coreboot firmware, I didn't backup a copy as I had already done so using the ChromeOS Recovery Tool.
I didn't create an OpenElec installer through the tool instead i created an 'installstick' using the software included in the download from the OpenElec website.
The issue I have now is that n that installer i get a black screen & then 'No Signal' displayed on my screen, even though the box is still on.
If I try to recover my firmware using my recovery stick it just hangs on a black screen with a load of text...sometimes it stops at the line;
"[3.315732] drm_kms_helper: panic occurred, switching to text console"
other times it stops at
"[3.348785] ---[ end trace 0a86c12e100920cd]
I'll be honest & say that I know very little about this (hence the reason for using the script) and I'm worried i've bricked my Chromebox after half an hour of having it
Any help would be much appreciated
[EDIT] - Still not sure what is causing the Recovery to fall over but I did manage to figure out that when i lost signal during the OpenElec installation, I just had to change from DisplayPort to HDMI...go figure
All is well & I am now running OpenElec, not sure if I'll run into the same issue should I ever want to put ChromeOS back on however...
