Chromium OS Special Builds

Chromium OS Special Builds are an enhancement to the default vanilla builds of Chromium OS to allow support for as many  devices as possible.

All downloads are located at and will be updated as new functionality is brought into the build as well as regular maintenance releases to keep the UI up to date.

Two deployments are currently supported, x86 (32 bit) and amd64 (64 bit).They are based on the x86-generic and amd64-generic overlays but have the following additional support:

The builds also allow Over The Air (OTA) updates from dev servers. From the browser, just go to Settings > About > Check for and apply updates and magic will happen. Updates will be automatic for builds after R46-7323 and will allow for development tools update with a single shell command:

sudo stateful_update

Install is exactly the same as

Have fun testing and using it. Feel free to feedback with whatever isn’t working as expected and I’ll try to build in to the next release!

Known Issues/Bugs:

In addition to the Special Builds, there are now enhanced Vanilla builds. These allow Google Drive integration and certain enhanced media codecs. This should allow the users with working daily builds more functionality and usability.

These Vanilla builds will also update automatically as and when I get the Update Server ready.

Please do not log issues with the Vanilla build since they are a courtesy build and will only work on devices with Freon supported graphics and CMT supported touch pads. WiFi and Ethernet will also have reduced support.

  1. Is there a special build for single board computers such as ASUS Tinker Board that supports Google Enterprise Enrollment?

  2. hi! Bought a cheap YEPO 737A with UEFI (AMI) (Intel N3450 CPU with 64GB eMMC and additional 120GB SSD). intended to use as testbed for our company.

    Somehow we got it to work partially via USB boot, but we can’t seems to get it work after installed chromium OS on SSD, can’t boot at all.

    Wonder if there’s anyone having similar experience and know the workaround?


    1. Hi!

      Managed to get Chromium OS to work on Yepo 737A under UEFI. However touchpad is not functioning.

      It seems that the touchpad will work after waking up from sleep, buttons and touch clicks still not working, only pointer movement is working. This does not happen eveytime, most of the time it just dont work.

      Learned that it may be bug in Linux kernel before 4.18. Wonder if I wanted to replace current CR 67 special build’s kernel, what should I do?

  3. Hi, after downloading and running from USB Everything seems to work fine but I can’t log in to my google account or anyone else’s for that matter. I can put my email address in and when it asks for my password it does show the correct avatar. I put in the password and it isn’t rejected, I just get a “please wait” and the spinning circle; I’ve left it for hours and I never can log in. I’ve also tried it on two other identical computers with the same results. I’ve installed Chromium OS and still get the same results.
    Computers are Lenovo R61i Thinkpads
    Build is Camd64OS_R67-10575.B-Special.7z

  4. I have R60-9592.B (Cx86OS) loaded on a Dell Inspiron Mini 1012 but can’t seem to get around an update required to use Google Play Store (notification states to log off and back in to resolve which doesn’t seem to work).

    Is there an update planned for the Cx86 platform or perhaps a work around available to get Google Play Store functional?

    1. Google Play Store isnt working right now.

      Also, no more updates are planned for Cx86 since its been removed by Google for support. Its far too complex and time consuming to keep it running.
