The issue
- We initially released this to security express on 13 December Friday. At that time, one of our test devices failed to boot, which we thought was a device-specific issue and thus we skipped that device while investigating, but released for the rest
- However, the next day, we got reports that the update won’t install correctly for some users, so we halted the rollout, and started trying to figure out what the issue
- Unfortunately we haven’t been able to reproduce and thus determine the exact cause yet.
- Thus, we decided to release it to at least beta and security express.
What happens
- The update should install fine. After reboot, if things are ok, you’re good to go.
- However, after reboot, if the device does not boot, it will continue trying to boot into this update at least 5 times.
- After that, if it still can’t boot, it’ll switch to the pre-update state and boot into that.
- You can continue using the device now, and see the below steps to remedy to avoid a repeat.

Steps to remedy
- If you’d like to help us figure out this issue, please contact us in the testers channel:
- Go to Settings -> System -> System updates. Tap “Release channel”, and select “Stable”
- Since this troublesome update hasn’t been released to “Stable”, your device won’t try to download the update again.
- If it’s already downloading, you can either let it reboot, or just skip the reboot.

Note
- Over-the-air(OTA) Updates: Starting from CalyxOS 7.2.2.0, CalyxOS updates resume automatically over the air. No manual install of updates needed. However, if you would like to manually update your CalyxOS device, see our OTA installation instructions.
- Security Updates for Pixel devices: The Pixel 9a, 9 Pro Fold, 9 Pro XL, 9 Pro, 9, 8a, 8 Pro, 8, Fold, Tablet, 7a, 7 Pro, 7, 6a, 6 Pro, and 6 stock OSes follow a monthly release schedule in direct alignment with the AOSP security bulletin. However, Google has stopped publishing the source code for AOSP QPR1 and QPR3 releases. As a result, CalyxOS is not able to timely include updates of the proprietary components, such as the bootloader, modem, and vendor firmware, for versions based on those specific QPR branches. The CalyxOS releases for the above models only contain the latest fixes to the open-source components, such as the operating system and the Linux kernel. Proprietary components get updates as soon as the corresponding AOSP source code becomes available.
- Security Updates for non-Pixel devices: The Fairphone 5, 4, Motorola moto g 5G 2024, moto g84 5G, moto g34 / g45 5G, and SHIFTphone 8 stock OSes follow a different security update release schedule, which is usually behind AOSP updates by a month or two. The CalyxOS releases for these devices only contain the latest fixes to the open-source components. Proprietary components get updates as soon as the stock OS update becomes available.
- End-of-life: The Motorola moto g52, moto g42, moto g32, Pixel 5a (5G), 4a (5G), and 5 are no longer being updated by the manufacturer, the CalyxOS updates for these devices only contain the fixes to the open-source components. Proprietary components no longer get updated.
