Installation Steps​

Go to “Settings > About phone > Software info” to confirm that your system has the correct version as listed above as per your device model:

Phone (2): Nothing OS 2.5.5

Phone (2a): Nothing OS 2.5.5a (Do not install on 2.5.6 or above)

Download the Update Package: Download the Android 15 Beta update package to your device.

Prepare the Device:

Create a folder named ota in the root directory of your internal storage.

Move the downloaded update package to this ota folder.

Start the Update Process:

Open the Dialer app on your phone.

Enter the code *#*#682#*#* to open the local update tool.

From the tool, select the update package you copied to the ota folder.

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.

Reboot the Device:

After the update process completes, a pop-up will prompt you to reboot the device. Confirm to restart and complete the installation.

Rolling Back to a Stable Build​

If you encounter issues and need to revert to a stable version of the OS:

Download the Rollback Package: Obtain the rollback package from the official source.

Follow Installation Steps: Follow the same steps as above, using the rollback package instead.

This process will again erase all your data, so ensure you have backed up everything beforehand.
