Okay, again with the same problem.
I tried using xboxhdm 2.2 with the C and E from the stock xbox, erased, formatted, said it found the files and asked me if I wanted to copy them, I said "yes". Then I ran "lockhd -a -k /mnt/sda1/eeprom/eeprom.bin /dev/hda" (I used tab completion so I know the path is right) and it popped up with all the info from the eeprom.bin file and asked if I really wanted to lock the drive, I said "yes" and then it said something like "HDD locked with Master password: XBOXSCENE".
Again, I went ahead and tried putting everything together and I still get the service screen error. This Xbox is 1.0, so unfortunately I get no error code. Red/Green flashing light.
I KNOW that I can hotswap, I've done it tons of times in the past couple of days without ANY error but with this console the hotswap doesn't work... is the HDD being locked with the wrong code? I can hotplug the drive into my desktop and unlock it with xboxhdm using the eeprom.bin file that I've generated. I've used PonyProg 1.17h and it dumps the same every time, just been doing the dump and checking against the console serial and then saving as a .bin file. I've tried Windows XP and Windows 7 SP1, both computers using a real serial port, not one of those USB adapters. Copying that bin straight to the eeprom folder in xboxhdm.
Am I doing something wrong during this process? Is there something else I can do to troubleshoot?

Could it be because I still have the EEPROM reader soldered on to the Xbox? Does the attached screenshot look right for the dump?
EDIT: An additional bit of info, I had flashing green failed bios load and added a wire to the bottom initially to get it to do anything. Could that have something to do with it?
Also, tried dumping eeprom like 10 more times, bit-for-bit the same every time. Removed eeprom reader and still the same results.
