Kled device not recognized

Support

Hi, my device (Acer Spin 713-2W) is not recognized anymore by the util script on debian 13: uname -rgives 6.12.48+deb13-amd64.

I made sure to boot the system with iomem=relaxed, and ran the script with sudo.

here is the output of the mrchromebox_diag.txtfile:

Any help welcome, I would like to revert the firmware to stock and this is a blocker.

looks to me like you ran an old local copy of firmware-util.sh rather than downloading it from my site first - am I correct?

It might be the case, I am not sure when I last updated the script :thinking:

In any case, I assumed my kernel version could have a role to play in this so I ran a fresh version from a live usb image and I was able to proceed with the flash recovery.

Maybe a self-update of the script could help avoiding this dumb issue in the future ?

Thanks for your excellent work btw!

it does bootstrap itself, but occasionally there are changes to the firmware-util.sh file, which is what happened here.
