just because it cannot be found by jungleflasher or fwtb doesnt mean that the firmware is corrupted keys can be stored in various positions 416a.40ec.401a.4116 and others, those flashing applications look for the common areas and if its not there flag up all zeros or key not within acceptible bounds message,I have seen a dump from OGGYUK that shows a drive back from microsoft with two keys in the firmware .yes they spoof drives too. LOL
 

That isnt entirely accurate.  Samsung keys can be in a great number of locations depending on what has been done to the drive (unlocking, etc...).  However, these positions are always predictable.  Typically what happens when a key cannot be found is that the user has attempted to unlock the drive but it failed.  During the unlock command, the key is written one location lower than where it is currently stored.  If something occurs (software aborts, etc...), then the key is typically written back as all 00's.  At this point, all of the software for finding keys in the fw will find the 00 key, except those that are written to check for repeating values, which would then report no valid key found.  I have seen many firmware where the user has tried unlocking about 50 times and somewhere along the line it aborted.

Well, you used to be able to update the dashboard by downloading the update on xbox.com, burning to a CDR then following some instructions.

Maybe you can force an update/reinstall that way? I doubt it though. I'm sure it does some check for version number and won't let you. But it doesn't hurt to try.

thanks for the tip, but apparantly yesterday there was an dashboad update available from MS. off course i was one of the first to update the dashboard, but i still have the same problem. so i gave up. the error can be in the ramchips, gpu, cpu or a combination or somewhere else. no way for me to find out anymore. so i will try to sell it and let another enthusiast try to repair it. the samsung drive should fetch a nice price i hope. untill then, it is a divx machine (that part works fine)
