How do yo get the backup? If you get back up from NT software then you have the right address already.

You do not seem to select the right target. The flash is 640 means it is 8M flash. The 9fc00000 should not be the address. It can be maxed for 4M flash.

He got Backup Using SBG900 as target, Therefore the Backup is No Good. He was missing the Porper XML file to be able to read the Full 8MB Flash. It has been taken care of and he Now Knows How to properly DeBrick the Modem....

That is exactly correct. The Netgear and the DPC2100R2 have same pinout.
All the member has to do is LEARN How to use the SEARCH TAB.

Here is a Helpful Picture
And here is a picture of the Adapter I make Based on that Diagram.

!!!!!!! Now STOP Being LAZY and learn how to use the SEARCH TAB !!!!!!!
