If a glitch occurred during the update, it can leave you unable to power on the Wi-Fi BacPac or connect to it in GoPro Studio. We have a new version of GoPro Studio that will allow you to re-establish connection so that you can update the BacPac.
Click here to download the latest version of GoPro Studio.
Install the new version of GoPro Studio and retry the update. You'll see that the Wi-Fi BacPac Version is listed as "Unavailable - Reconnect". That's OK. Click the UPDATE button anyway, and the update should complete successfully.
