Is it impossible to restore a "rooted android" back to the original factory setting?

[2gcard3gphone]

I guess many ppls asked online about the same question but none of them got the answer, probably because ppls'd mistaken it... so i would put it this way by history



Day 01 New Bought Android = "Original Factory Setting" with "factory root"



Day 02 Installed market or nonmarket apps = "no original factory setting" with "factory root"



Day 03 Factory Reset = "Original Factory Setting" with "factory root"



Day 04 Rooted the android = "no original factory setting" with "no factory root"



Day 05 Is it impossible to return the phone to the status of "Day 01" or "Day 03"?

Should be possible if you made a backup in recovery on those days
