# Local Upgrade

If your device fails to upgrade online, you can try the following local upgrade method:

1. Prepare a Windows-based PC and ensure it is connected to the same local network as your device.
2. Open a browser on the PC, enter the upgrade link, and download the firmware file.
3. Once the file is downloaded, use file server software (such as [HFS](https://drive.google.com/file/d/1uxIDG8idh6xt142YyitusHnHzvOJgsQ7/view?usp=sharing)) to create an HTTP link pointing to the location where the firmware file is stored (please note that HTTPS is not supported).
4. Send this HTTP link to the device via the upgrade option in the app to perform the firmware upgrade.
