Is this the MCU bootloader on the BL653 DVK board or an MCU bootloader on the onboard nRF52833? If it's something specific to the BL653 DVK I think you need to ask Laird about that.

As to how to create a botoloader package using nrfutil that is explained by my colleague Terje in this ticket. Then you need to move the bootloader file over to your Android device and connect to the device you want to do a DFU on.

Best regards,

Simon

I think you need to provide some more information on what exactly you'd like to do here. What SDK and SDK version are you using, is it the MCU bootloader or the application on your nRF device you're trying to update here? Here for example is one of our BLE secure DFU bootloader examples with a step-by-step guide for setup and testing. Would also be helpful to know what nRF device you're working on.

Best regards,

Simon
