020 or 0020?
In case of 0020, my Zephyr elite got that error after 6 months of usage, never tocuhed it since then but im planning to attempt to fix it soon.
EDIT:
Forgot to ask if anyone ever got the RROD with the following quadrants flashing:

1, 2, 4. Happened 10 min ago while running a game of HD (jtagged) screen stayed black > shut down the xbox, turned it on again and it flashed... but! while it was flashing it booted and worked just fine
Another reboot made it disapear again
I thought it just gave me only three numbers when pressing sync but it must be 0020.
It's still going since my Feb 8th post, I've 1000'ed four games with it and this is a 2006 Hitachi model that the previous owner red ringed twice, x-clamped and gave it an unhealthy amount of towel tricks, he gave it to me with a e74 screen.
When I went to remove the graphics heatsink I had to really give it some with the spanner to loosen the bolts. The person who x-clamped it had tightened them like he was putting a car wheel on, unbelievably tight.
I cleaned it up, new paste, re-tightened them myself with a spanner but not much and it didn't work. I loosened them then re-tightened them without a spanner, just as far as my fingers would allow and it's worked ever since.
