How to upgrade to Android 15 Developer Preview
Go to “Settings > About phone > Software info” to confirm that your system has the correct version:
Phone (2): Nothing OS 2.5.5
Phone (2a): Nothing OS 2.5.5a (Do not install on 2.5.6 or above)
Create a folder named “ota” in your device’s internal storage directory.
Copy the package to the “ota” folder.
Go to your phone’s dial screen and enter the following code: *#*#682#*#*
- The local update tool will now open. In the drop-down list that appears, select the upgrade package you just copied.
* The drop-down list will display all files in the “ota” folder - you can update the list by tapping the “RELOAD” button.
* If the upgrade package does not appear in the drop-down list, tap the “Browse” button to select the “ota” folder and then select the upgrade package.
* Please make sure you have prepared the correct upgrade package for your device. If the upgrade package is wrong, it will show an error prompt “Verify metadata file status”.
- Tap the “Directly apply OTA from selection” button to start updating.
* Please do not remove the app from the background during the update as this may cause issues with the updating process. It is recommended that you keep the local update tool until the process is completed. This will help ensure a smooth and successful update process.
- Reboot your device
After the upgrade process is complete, a pop-up will appear asking if you would like to reboot your device. We strongly recommend selecting “Confirm” here, as upgrades require a reboot to enter the new version.
- Upgrade successful
