Roku Express Software Update

My Roku Express carried out a software update last week, now every time it's turned on, it's stuck at the bouncing logo. Before the update it was working perfectly

I've tried the fixes listed in various places, reset button 10 seconds, reset button 30 seconds, power cycle, nothing works, still stuck on the annoying bouncing logo.

Seems the update has broken it.

Any more ideas to fix this would be welcome, thanks.
