I would be really curious:
>You bought a mobo from WHAT e-tailer?
Then you sent it back for RMA and they came back and said
their supplier said your board has user caused damage?
Never RMA a mobo without videoing the condition of grid and you carefully reinstalling pin protector

Fwiw the ASUS Z77 have the plastic pin protector on
top of the clamp plate and you close the plate (with CPU in) and the pin protector pops out.(or you can manually remove it)
>Does the ASRock still have the protector on top of the LGA grid under the clamp plate?
Early on when I saw how incredibly fragile the 1155 2011 LGA were I just bought a childs dart set at KMart $5. I cut the shaft so that the plate rotating down clears it and stick the neoprene tip in the center of CPU, easily lower it to socket, clamp CPU and slide dart off sideways
