So, I’ll admit I did something dumb, I was reinstalling ChromeOS and was at the recovery screen. I had a USB stick with the correct recovery image for my device, but the recovery image itself was an older version. I heard and wanted to see if older versions were more lightweight. I plugged the USB in, and it attempted to recover, eventually it failed because the image was too old. Then it started undoing its changes. But I had read it failed, so I without thinking, powered it off. Now when I open it or try to turn it on, nothing appears on the screen. I want to think the bios is damaged and it can’t do anything. Lastly if this info helps, the battery lights still react to getting power. (Chromebook: Acer Chromebook CB5-132T).
If your firmware is damaged you need a SOIC clip and a Raspberry Pi so you can hook the firmware chip up to the GPIO pins and use flashrom to reprogram it.
Unless you disabled WP, then recovery didn’t touch RO firmware. Can you still boot into recovery mode?
