Before you proceed, follow these steps to avoid "bricking" your modem. Install the latest Huawei Mobile Partner or Huawei

Open a web browser and enter (the default IP for HiLink modems). Navigate to Settings > System > Update (or Manage Updates ). Navigate to Settings > System > Update (or Manage Updates )

With the modem disconnected from the PC, press and hold both volume buttons (Volume Up + Volume Down). While holding them, connect the modem to the PC via USB. Keep holding the buttons until the computer recognises the device and the flashing process begins automatically.

If your E303s-1 works and connects to the internet, you likely do not need to update it, as the benefits are marginal for a legacy 3G device.
