What happens if I restore my phone with developers preview?

My 920 has some software fault, so want to wipe it. What os will I get when it comes back?

Your phone OS and firmware will remain the same. Your phone will revert back to windows phone 8.1. To downgrade it to windows phone 8.0(expect if your device has Lumia cyan-Lumia 92 and 625 ) you can easily downgrade to windows phone 8.0 via nokia recovery tool :smile:
