Unsupported Disc, Stock Firmware Options

[lord^infamous]

I have a jasper here that needed the dvd key recovered so I RGH'd it. Things went smoothly and got the CPU and DVD key. When I dumped the nand, the xbox was stuck trying to update from 13146 but failed because the dvd drive was not connect. So instead of flashing the key to the new dvd drive first and proceeding with the update, I updated the dash to 14699. Yes, I know this was a mistake. At first I was getting RROD 0022 with stock 14699. My mistake, so I opened the 14699 nand to find the LDV value was 6 but should be 7. Patched it to 7 and now boots just fine. Dvd drive works and recognizes all my originals but I get "this disc is not supported" after trying to boot the game. Identical behavior of back ups that fail the recent AP2.5 checks. I opened the nand with 360 flash tool thinking the OSIG was wrong. The 13146 dump and 14699 both say 93450 but shouldn't they both say 02510? Never the less, I have tried stock 93450 and stock 02510 and both give me unsupported disc. Ideas?
