Legacy Slot Support for the Acer C740/Chromebook 11 and Acer C910/Chromebook 15

I’ve had a working updated legacy slot for the Acer C910/Chromebook 15 since mid-April, as some of you in the community may know. I took a few minutes tonight to incorporate that into the script, and I’ve also made it available for the Acer C740/Chromebook 11 (not that I’ve come across anyone who has one yet, but you never know). See the ROM Download page.

  1. Thanks for the great work John. I recently got a C740 and I like it a lot. Besides the chipset it is a considerable improvement over my C720 in terms of build quality (in particular the back of the screen), and the keyboard is improved too (less noisy/flimsy). It would be great if your script could eventually fully support/flash C740.

    Anyway, I just tried the script to flash the legacy slot but it seems that it does not recognize the device (“something went seriously wrong”). I had a look in the script and there does not seem to be a “newromname” entry for Auron_Paine.

    Feel free to reach out if you need more info, or if you want me to test some more.

  2. Hi,

    I have the european Acer C910 (CB5-571), and I get an error that “Block protection could not be disabled!”. Maybe I do have to unscrew the write protection screw?



  3. Ok great! I’m typing this from my chromebook running elementary now, thanks so much!

    One quick question:
    Am I right in assuming that a full battery drain will cause legacy boot to be disabled? Since I wiped chromeos it would not be possible to enable it again without restoring.
