Unable to burn custom firmware.

[Gova]

I was able to create a Distribution package with the command as shown in the following photo.

I have taken the zip file from email app in my iPhone and have opened in thingy app. After that I am unable to burn the latest firmware even though I am able to select the same in my thingy app's inbox. Please watch the video in attachments to know my problem. Any help would be appreciated. Thanks a ton in advance.

You do not have the private key which corresponds to the public key in the factory programmed bootloader on the Thingy so you will not be able to update the application via OTA DFU.

The Over-the-air device firmware update section in the Thingy User Guide describes how you update the application that is made by Nordic Semiconductor through the Thingy app. It does not cover how to update your own application, which requires you to compile your own bootloader with your public key and flash the bootloader using a programmer and a cable.

You should look at the nRF5 SDK documentation on the bootloader, see this page on Infocenter.

@govardhanan (Gova): Yes, you are correct.
