App’s purpose
Android OEMs roll out OTA updates in a staged manner, meaning you might have to wait a long time before receiving an update. That’s where this app comes in—you can download official OTA ZIPs directly, with built-in MD5 checksum verification. They're the exact same files as system OTA, except we're faster 99% of the time. By doing so, this app lets you skip the rollout queue and install official updates ASAP.
Note: if you’re not receiving notifications, double-check app & Android settings. Also disable battery optimizations: https://dontkillmyapp.com/oneplus#user-solution.

Supported devices
All devices that aren’t carrier-branded (e.g. T-Mobile & Verizon) work perfectly. Carrier-branded devices run a custom, completely locked-down OxygenOS/ColorOS flavour. If you own such a device, be aware that you cannot manually update your firmware, even if you don’t use our app.
See https://oxygenupdater.com/ for a full list of supported devices, and https://oxygenupdater.com/faq/ for frequently asked questions.
Works perfectly without root
If you grant root access to the app, there are some additional features you can take advantage of: "become a contributor" feature, which tries to submit OTA URLs captured from your device (opt-in), and improved update method recommendations (full vs incremental).
If you want to update a rooted device while maintaining root, follow these steps:
1. Install via “local upgrade” as you normally would, but *DO NOT* reboot
2. Open Magisk and select the “flash to inactive slot” option
3. Reboot and enjoy
Supports all update tracks & package types
Tracks:
• Stable (default): supposed to be pristine quality, daily-driver material
• Open Beta (opt-in): may contain bugs, but you can experience new features early
• Developer Preview (opt-in, if available for your device): unstable, meant only for developers or hardcore enthusiasts
Switching between different tracks may require enabling “advanced mode” in the app’s settings.
Package types:
• Incremental (default): much smaller than full, meant for a specific source → target version combo (e.g. 1.2.3 → 1.2.6). Incompatible if rooted, standard Android behaviour. Note: app falls back to full if for whatever reason an incremental isn’t available.
• Full: contains the entire OS, so they’re quite large. Uses: switching between different tracks, or upgrading to a brand new major Android version (e.g. 11 → 12), or if you’re rooted. In all other cases, incremental is recommended.
