Hi, How to upgrade build number? My Blitz is having Z9-KY-V03.

Hi,
How to upgrade build number? My Blitz is having Z9-KY-V03. I am using Wireless Upgrade and see a message saying “This version is not configured in FOTA server”

I need help with this too! :frowning:

I wrote to the vendor and they sent me instructions to do it. Try that.

Do you happen to have the instructions you could send over?
