Is there an official GooglebookOS ISO?

No. Google does not publish an ISO file for Googlebooks. GooglebookOS (Aluminium OS) is distributed as an official recovery image, a recovery.zip file, which you write to a USB drive with Google’s Recovery Utility. The GooglebookOS downloads on this page are those official recovery images.

What is the GooglebookOS firmware or recovery image?

It is the complete factory software image Google publishes for each Googlebook model. Restoring it reinstalls GooglebookOS to the latest released build and erases everything stored on the device.

Which GooglebookOS recovery file do I need?

Each Googlebook model has its own image, and images cannot be swapped between models. Search for your exact model name or codename above and download the file listed for it.

How do I install a GooglebookOS recovery image?

Download the recovery.zip for your model, insert a USB drive of at least 32 GB, open the Recovery Utility extension in Chrome, choose “Use local image” and select the file. Then start the Googlebook in recovery mode and follow the on-screen steps.

Are these downloads safe?

Yes. Every file is downloaded directly from Google’s own servers (dl.google.com). This site never hosts or changes the files, and you can compare the MD5 or SHA-1 checksum shown for each image.

Can I also download ChromeOS and ChromeOS Flex images here?

Yes. The Chromebooks tab lists the official ChromeOS recovery image for every Chromebook, and the ChromeOS Flex tab has the USB installer image for PCs and Macs.

How often is this list updated?

Automatically, every hour. New GooglebookOS and ChromeOS builds appear here shortly after Google publishes them.
