More to add, fixed a rrod falcon right on the spot at my birthday so we could continue playing after the other kid had to leave (actually fixed prior that week as well) That falcon had one f**ked up error code, you would press sync and eject and it would keep saying 0 or 1 and would never go back to the rrod once and a while it would give others but almost would never return. I took my chances and it worked, although we had to overheat in the process and we thought it was screwed because it took almost 20 minutes to overheat so we boiled some water on the gpu sink for fun. After it cooled down and after the strangest error codes we had it worked. Go figure. I think the other kid had Zephyr but I am not positive, broke while we were flashing, go figure but it all turned out good in the end.
