How to sell a Windows Phone on 8.1 Preview ?

[WPCentral Question]

Long story short I am thinking of selling my 1020 and going for the 1320 but I updated my 1020 to the 8.1 preview and now can't restore to factory settings so how can I get it ready to sell on ? Or should I wait until the Official update is released?

1) Settings > About - reset. It will still have 8.1 but without your ID (live account)
2) You can use Nokias recovery software to downgrade to 8.0

I would just reset it as AV2RY said and sell it as is. Just note the inclusion of 8.1.
