Stuck on Recovery screen, errors. Help!

So recently my Huawei p8 randomly wouldn’t turn on, and when it does it takes me straight to the Rescue mode which says ‘Please update system again!” With the errors:

Func NO : 9 (dsp image)

Func NO : 1 (security verify failed)

I have managed to get onto the EUI screen or whatever it is and done a reboot but it takes me back to this screen.

I’m not very advanced on Androids so I’m not too sure what I need to do in order to fix this. Help would be appreciated. Thank you.
