Which form should I fill to restore the denied I485?

Hi,

I filled I140 and I485 concurrently in the beginning and both of them were denied. I appealed my I140 and it was approved. I want to restore my I485. Does any people have such kind of experience? Which form should I fill? Most information I searched indicate that I could not reopen/appeal I485 that has been denied. Thank you very much for your information.
