Recovery Guide
Restore updates when WingView rejects a valid firmware build.
Restart WingView when an update fails but the board otherwise works. This restores the previous firmware version. Your Wi-Fi, API key, locations, and maps remain saved.
When to use this guide
Use these steps when an update fails with a message that the file is invalid or the build is not accepted. Use them only if WingView otherwise works normally.
Restart WingView
Open WingView's web page.
Select Restart at the bottom of home.
If you cannot open the page, unplug the board.
Wait five seconds.
Plug the board back in.
The bootloader performs the repair before firmware starts. Either restart method has the same result.
After restarting, WingView runs the previous firmware version. You can install updates again.
A restart never erases your Wi-Fi, API key, locations, or maps.
Install the update again
Wait for WingView to start and show aircraft.
Open the web page.
Go to firmware.
Confirm that the displayed version is older. This is expected.
Select Check for update.
The update should now install normally.
Why this happens
WingView keeps the previous firmware until a new version proves it can run. A new version gets about one minute to confirm itself.
Until confirmation completes, WingView does not accept another update. This protects the known-working version.
An unconfirmed update can leave WingView working normally while it refuses every new update. Restarting returns to the previous version and clears that state.
If restarting does not help
A continued update failure has a different cause. Send the log to support:
Open the board's web page.
Go to log.
Select Show additional details (for support).
Select Copy all.
The log removes your Wi-Fi name, API key, passphrase, and coordinates before copying.
