No official firmware recovery or bootloader recovery procedure for Microsoft Wireless Display Adapter V2 (Model 1733) is provided in the available guidance.
The supported firmware update path requires the adapter to be connectable from a Windows device through the Microsoft Wireless Display Adapter app:
- Connect the Windows device to the adapter.
- Open the Microsoft Wireless Display Adapter app.
- Select Update & security.
- If an update is available, select Update and keep the app open until the update completes.
If the adapter never reaches a usable state and never becomes connectable, the available guidance does not provide an offline firmware recovery utility, forced recovery mode, or USB-only reflash method.
Supported troubleshooting steps are:
- Install the latest Windows updates.
- On Windows 11: Start > Settings > Windows Update > Check for updates.
- On Windows 10: Start > Settings > Update & security > Windows Update > Check for updates.
- Verify both adapter connections.
- HDMI connected to the second display.
- USB connected to a power source.
- For the most stable connection, use a USB power source directly connected to a wall outlet.
- Confirm the adapter is powered correctly.
- The guidance specifies using a USB charging port that provides at least 5W (5V/1A).
- Keep the device within 23 feet (7 m) of the display and connect the device to Wi‑Fi before connecting to the adapter.
- Restart the adapter.
- Remove the adapter from the display.
- Restart the Windows device.
- Reconnect the adapter to the TV or monitor.
- Try to cast again.
Based on the available guidance, if the adapter never progresses past the Microsoft logo and cannot be connected to by a Windows device, there is no documented self-service firmware recovery path. That makes hardware failure or a non-recoverable adapter state more likely than a recoverable firmware issue through supported tools.
