Mini controller won't stop beeping after software upgrade

[Chrispycrutch]

Hello there

Complete novice here looking for help and divine intervention, finally decided to unbox my mini having had it for several weeks, everything going well until the software upgrade now the controller will not stop beeping, any help and assistance will be gratefully received.
I only wanted to do a first quick test flight aghhhhhhhh.
Thank you

Sorted, had to download the updated software via DJI Assist to my pc then connect the Mini and update from there
