Revert back to 4.2.0 from 5.0 version stuck at connecting to wiifi

So I’m trying to roll back to 4.2.0… but during the procedure it wont go past “connecting to network”. I get a confirmation from homey that it has sucsessfully connected to my network, but it just keeps loading and loading on the screen and eventually goes back to the first setup screen " Connect to HomeySetup"…
Any help is greatly appreciated.
