Restoring to the original San Francisco Rom?

[Guest hillmie87]

Bear with me, a complete noob here.

You know, paul made a pretty nice tutorial of how to root the san francisco and flash the custom rom.

But can someone be kind and do a tutorial (or write an instruction) on how to restore the original orange rom.

You know, in case someone need to send their san francisco phone back to orange shop for repair or something.

:)

regards.
