Hi Yangbo,

With the lower version of Device Manager installed, you would simply replace the database in the AS. Downgrading and retaining the db is not an option, but would rely on a previous backup of the db from the lower version.

Hi Houston

Thanks for comments.

I tried many times, but every time failed. See the capture below, any comments.DownGrade Failed From 1.5 to lower.png

I'm pretty sure that as of 1.5 you need to enter DFU mode (three clicks on the pin) before you can downgrade, but that's just off the top of my head

There's a hole in the front where "RESET" is written
