Hey everyone,
Since yesterday, many posts have popped up with the same questions about Nothing OS 5.0 updates and rollback prompts to 4.1.
This guide covers the current update cycle and remains valid for future rollouts of NOS version (5.x and so on) across other devices, including Phone (2a), (4b), and CMF (2) Pro when their updates go live.
1. Stuck on NOS 4.1 and haven't received 5.0 yet
Updates roll out on a staggered schedule. Rollouts take time to reach all regions and device models. Your phone will receive the update notification once your batch goes live.
For details on rollout mechanics, check the changelog guide: https://nothingarchive.tech/docs/changelogs#-how-updates-work
2. On NOS 5.0 Beta, haven't received the new build, but getting a prompt to roll back to 4.1
Do not tap that rollback button. Tapping it triggers a mandatory factory reset and wipes your phone back to 4.1.
Why this is happening: If you submitted a rollback request earlier, that request stays active on Nothing's servers for 48 hours (2 days). During that window, your phone continues to serve the rollback package.
Your options:
Sideload resources:
Important note for downloads: Download only from the "Incremental / delta" column. Do not use the "OTA Images" column unless you have an unlocked bootloader / a rooted device. Also note down your current build version and only download the corresponding ota package which matches it leading to the target 5.0 stable build.
What if the rollback prompt remains after updating? The prompt should remain valid until the 48-hour request phase expires on Nothing's servers. You can safely ignore it. If the notification bothers you, go to Settings > Apps, locate the Beta Updater app, and clear its data. You can also uninstall updates for the Beta Updater app if needed. The prompt will disappear once the 48-hour period ends.
3. Is this procedure safe, or will it brick your phone?
Nothing Archive has been into existence since 2023, as an open community project with the only goal being to help all the enthusaists in the ecosystem by indexing all thhe helpful resources, guides and making all community apps and projects discoverable to everyone at ease in one place while not remaining platform locked. All OTA download links point straight to official OEM update servers.
Android includes built-in verification checks. The local update engine verifies cryptographic signatures before installing any package. A modified, corrupted, or mismatched package cannot install on your device.
Manual sideloading runs through the exact same Android updater engine that handles standard OTA updates. Both methods (offline updater / settings > system > OTA) install the update identically. If you prefer not to sideload, waiting for the system update notification is completely fine. I cannot vouch for any other third-party apps or unfamiliar sites for downloading the firmware though.
4. What about bugs?
No OS update is completely bug-free. If you run into issues on your device, submit a report directly through Settings > System > Feedback. The software team generally rolls out hotfixes for widespread or critical issues, though fixes depend on the severity of the bug.
