It took me a while to find this thread. I have the same problem on my HG retail cart/NitroHax, I'm also in to deep to restart, and the codes didn't work for me either... so bumpity-bump.
UPDATE: The delete/restore phrases codes did the trick on the second try! Trading as I type!
To recap, first I used only:
This will wipe your phrase database. Then save, power-off, go back into NitroHax (or whatever AR-clone you use) and enable only:
Use this to restore your phrases, then save. If you're lucky, you should be back in bweezness.
Best of luck, and I sincerely hope you all will be trading again soon.
