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 http://chromium.arnoldthebat.co.uk/index.php?dir=special 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 http://arnoldthebat.co.uk/wordpress/chromium-os/

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: https://github.com/arnoldthebat/chromiumos/issues


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?

    thanks

    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.

  5. Hey arnold! thank you very much for your builds, especially those special builds run really well on my 2in1 convertable besides one problem. I don’t know if it’s related to the ISO but when I put this ISO on a 16GB USB stick and install chromium os on my laptop using “sudo /usr/sbin/chromeos-install –dst /dev/sda”, then apparently my sda3 and sda5 partitions will be too small to copy data from recovery images. My sda5 partition is for example 2GB which is too small because the recovery image contains like 2.1-2.4GB. There are plently of tutorials to upgrade chromium to chrome but no one tells that these partitions are too small for some reason. Is there something you or I can do about it?

    regards

  6. Hello.

    On both the special and daily builds, my microphone is detected (I can view and change the sliders in alsamixer, and lspci shows the audio device), but it does not pick up audio.

    In alsamixer, it’s listed as “HDA ATI SB”, and in lspci, it’s “00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 Azalia (Intel HDA) (rev 40)”.

    Also, microphones plugged into the mic jack do not work, but USB mics work.

    Was wondering if there’s something I could do to get it to work. If not, that’s fine. Everything else works wonderfully, though.

  7. i installed th R69 on my toshiba satellite C850 everything work. Except the play store
    I’m waiting for the next version with play store

  8. Whoops. Posted in a comment wall for an older build. Internal mic and mic jack are not working. Card is “HD ATI SB”, chip is “Conexant CX20590”. USB mics work. Turned up the controls in alsamixer, but the mic does pick up anything.

  9. Hello, I can’t find x86 version after August 2017 of this build, will you plan to build/upload one soon or should I try to force an amd64 one to boot on my 32bit only uefi tablet ?

  10. Hello, thank you so much for your work you literally saved my Chromebook Pixel after it has reached EOL. But I have couple of problems. The first one, when I insert my headphones the sound still comes out of my laptop speakers even though it does recognise the fact that headphones are plugged in. The second problem is small but really annoying, when i put two finger on my touchpad the page starts flicker up/down.

    Can I integrate drivers from my original recovery image? I’ve tried to copy firmware and modules folders from original image to my lib folder but it doesn’t work as expected.

      1. Thank you, for your reply. Yes, it’s my chromebook. I’ve partially solved audio problem by unmutting headphones channel in the alsa-mixer though headphones sound is extremely loud. But the main problem is touchpad. I’ve tried to use atmel’s mxt-app utility to export/import touchpad settings but unfortunately it doesn’t help. If I understand correctly I should find somewhere the source code of my drivers and try to compile it with kernel-4.4 headers. Or maybe it’s the problem with the firmware? But I’ve tried to copy firmware folder from the original recovery.

      2. What’s interesting, running original chrome os image lsmod | grep atmel doesn’t show atmel’s driver but
        cat /proc/bus/input/devices shows
        I: Bus=0018 Vendor=0000 Product=0000 Version=0000
        N: Name=”Atmel maXTouch Touchpad”
        P: Phys=i2c-1-004b/input0
        S: Sysfs=/devices/pci0000:00/0000:00:02.0/i2c-1/1-004b/input/input8
        U: Uniq=
        H: Handlers=event8 cpufreq_interactive
        B: PROP=5

        B: KEY=e520 10000 0 0 0 0
        B: ABS=671800001000003

  11. Tried using CSM (legacy BIOS, secure boot off) on my Asus ROG GL702VM to boot the latest amd64 variant special build, and syslinux hangs at “booting Linux” as shown here: https://photos.app.goo.gl/gABStB5M8Y4S7HsU7

    The alt + print screen (magic SysRq key) didn’t work to force it to reboot. Is it even possible for the builds to boot?
