I need to find the original firmware for an ms25 samsung. Someone brought me an xbox 360 that had a bad flash so I fixed it and I'm getting an E66 code now and need to put it back to the original firmware to test it and they no longer have it. I was able to extract the drive key so if I can find the original FW i should be able to use FWtoolbox to rewrite the .bin file. If anyone has one or knows where I can get it please let me know. I tried searching already but no luck so far.
