Hi guys! I have a problem with the Acer Chromebook 516 GE machine. I installed Windows 11 according to MrChromebox’s instructions. But when I want to reinstall Chrome OS, I flash the firmware on Unbutu as instructed by MrChromebox but when I plug in the USB Recovery OS, the machine says “No Valid Image Detected” and optional Recovery with the Internet is also unusable! Hope you guys can help
Press tab and send a picture of the debug info.
Did you use your original ROM file? I don’t remember ever seeing the “developer signed” text at the top of the screen
I use USB recovery but it doesn’t
That version string means it is production firmware, but somehow devsigned? Did you restore your own firmware backup?
Edit: Look at it again and realized it’s the same firmware version in both ro and rw.
I flashed the backup rom before installing mrchromeboxI flashed the Backup ROM before installing MrChromebox! Can you help me fix this error? Please
