Important

You downloaded the bootloader (boot or bootnsoft) and the application (app) programs above for the BLU2Pro. We released two different update versions: Standard and Alternative. Alternative units were shipped up to February 2022 and the Standard units shipped from March 2022 until today. The only difference is the way they update. 

There is no harm in choosing the wrong file. You can not break your unit by choosing the wrong version. 

Which Version, the easy way

If you still have the packaging or have the FCC label on the bottom of your device, take a look at the version on the label. If this says V1.01.00 you will be using the alt updates. You'll use the standard for everything else. 

If you don't have this sticker, you can go by when you received the unit using the below table. 

If you updated the camera yourself, that is the version you have now. 

Android

Until our official app is launched, you can manually update your BLU2Pro on Android using the below tool. Please follow these steps: 

1. Download all four files from above. Please have a look at the version section if you haven't already. It's super helpful. 
2. From Google Play install nRF Device Firmware Update (Android) onto your device.

You'll now be able to connect and reconnect to the GoPro HERO11 Black/Mini. You'll notice the change in the LEDs pattern when connected.

1. Download the necessary files from above. 
2. From App Store install nRF Device Firmware Update (iOS) onto your device.

The blue standby LED will be locked in this case. A battery pull is needed to restart the camera if this occurs, powering off will not fix it!
