Hehe, looking back I guess it looks like I was frantic? I was methodically going through what I knew about. I have been at this for two days now ;) I still cannot load the "Global Defaults" dump or anything besides the Bulk dump. I am going to assume it's a compatibility problem and move on to creating patches.
Thanks for the tips! If you need any pictures to improve the manual let me know. I still have everything loose.

I have gone around a hit all the chips solder points and even pulled the EPROM to make an image of it in case that was bonky. I only saw one difference from the file online and I assume that's because you have changed something since the file was uploaded. Address 0x10 I have CC instead of C4. If you don't have any other tips I guess my next step is to de-solder the EEPROMs (ugh) and blank them out with my burner.

This time it failed with a 4 showing. Is there a way to access the memory at the moment of failure? I really don't see how I am able to do all this other stuff and it be a hardware problem. It takes a very long time to fail, like it just runs out of room or something. Is that possible?

I have also copied the standard patches over from ROM with no problem (diag 6). I have seen two more failure modes now that I have tried a few times. The one time I did it, there was a 4, then a C, but mostly an H. Yes it is in the position where the word PATCH would be. I always have to "reboot" at that point. There is never a PATCH5, so I'll go back and touch up my soldering. Hopfully I find something there or I get lucky and it will just start working after I re-touch all the contacts.

Because when the display is showing PATCH4, the HAWK software is copying the uploaded software from RAM memory into the patch EEROM. And if it is able to successfully copy over all of the patch data then the display changes to PATCH5. And PATCH5 is the message that is displayed while the HAWK does a data integrity check. The integrity check only happens after all of the data is copied into the patch data EEROM.

They show "Error 2" in this "Diag 8" mode and I can't seem to find any other reference to a different mode. As you can see I'm a little confused... don't use SYSEX much.
