Hi Jamie!
Yes ofcourse!
I have procedure how to restore Homey but it doesnt work for me.
Now i made factory reset one more time but still V5.0.xx load.
What i was doing:
1.Checked in homey developer that experimental tab ticked off
2.Checked in Homey app that all experimental ticks are off and ticked of automatic update.
3. Chrome web browser open setup.athom.com , proced until when need to connect to Homey setup SSID
4.Turned homey upp and down, count from 10-0 , connected to Homey setup SSID.
5.Now i made choice of Dont connect an athom account with ALT button option.
6.After that it warns to put back Homey on leg , after some time Homey told me to connect again with setup.athom.com and only option ihad was to connect with my existing account.
7. After setup i have still Same V5.0
