These files can simply be downloaded and copied to your microSD card to reset your GoPro Hero 3+ or your GoPro Hero 3.

Files:

• GoPro Hero 3+ Black.
• GoPro Hero 3+ Silver.
• GoPro Hero 3 Black.
• GoPro Hero 3 Silver.
• GoPro Hero 3 White.

(Note: All GoPro Hero 3 series files are the same).

How to Guide:

• Download the file for your specific GoPro model (the list of files is below).
• Insert the microSD card into your computer (using a microSD to SD adaptor or microSD to USB adaptor). NOTE: The microSD card does NOT need to be formatted, you can keep your current recordings on the card.
• Unzip the file on your computer.
• Copy the files to the microSD card.
• For the GoPro Hero 3+, the files need to be in a folder called “UPDATE”. Make sure you copy the folder to the card. It will not work if the files are not in the UPDATE folder.
• For the GoPro Hero 3, the files need to be in the root directory of the card, NOT in a folder. Copy the files directly to your card, not in a folder. It will not work if the files are in a folder.
• Eject the microSD card from your computer.
• Insert the card into your GoPro whilst the camera is off.
• Turn on the GoPro, it will come up with a screen saying it is updating, and turn itself off when complete.
• Turn your GoPro on and connect to the WiFi using your device.

In the files, the WiFi details are:

• SSID: GoProHero
• Password: goprohero

If you want to customise the SSID and password, edit the “settings.in” file with Notepad/TextWrangler/similar. In the file you will see two lines with: "ssid":"GoProHero", "password":"goprohero"

– edit to your desired combination.
