Downgrade Galaxy S Duos from ICS to Gingerbread I want to downgrade my Galaxy S Duos from ICS (Ice Cream Sandwich) 4.0 to Gingerbread. How do I do this?
Galaxy S Duos was released with the ICS onboard and there is no Gingerbread available for this model. You shouldn't use a firmware designed for other devices from the Galaxy family - this is an easy way to brick you phone.

"Getting Prepared" instruction is irrelevant.
