I have my xbox torn completely down, heat sinks off, chips cleaned up, and supplies bought (ie. Sticky putty, tinfoil, thick plastic sheet, 1200W heat gun). I am ready to do this re-flow I have already done the x-clamp fix, and 12v fan mod along with ducting, this is my last resort.. However I do have some questions.. What gets the heat? Bottom Side: Under the GPU, CPU, 4 RAM and HANA chips? Top Side: GPU, CPU, 4 RAM, HANA? ^^ Correct?? ^^ What is the other big chip that is off to the side of the HANA and in front of the video plug in? I am getting a weird error by doing the Sync and Eject procedure.. I get four really quick flashing lights, then one quick flashing light, then three quick flashing, but then i get two slow flashing lights.. which I think are the original two RROD before doing the sync eject thing. Does this mean a three digit code of 013? or a code of 0132? It is an unknown code from what I have seen. Two RROD shows error codes 0011, 0012, and 0013. I get two RROD immediately after starting up, this must be done.
I do 1 minute on the low setting on the bottom heating the entire board. This is basically a "poor man's griddle/bottom heater" where you're trying to avoid thermal shock. Then on the top I hit all the chips you mentioned plus the southbridge (that other chip). Sometimes the break can be under there, sometimes cpu/gpu, hana or ram...you cant tell without an xray so I just hit them all.
I think that w00ly means the 1 minute on low heat on the bottom of the board simulates the preheat phase whilst reducing the chances of warping the mobo etc.
did the reflow, was not a success. must have not gotten hot enough.. its scary your first time! that air coming out of there is CRAZILY HOT. lol I did get further in to the load up sequence tho.. so it was not a total loss. it just needs more heat. So i was getting 0013, now i am getting 0012 both 2 RROD. SO it looks like 0013 was a RAM over heat, where as 0012 is a GPU overheat. Does it just need another go with the heat gun? maybe a little closer to the mobo? I was about a fist and a half up on high when i was doing it... seriously afraid of wrecking things!
