It doesn´t matter if its chiped or flashed... in both cases the console was opened and MS will know... or do you guys think Bill Gates has those huge glasses for no reaon ???
Best bet is to find someone reliable who can fix it at a good price... doing the X-clamp fix and adding an additional cooler will fix the problem for good im 95% of all cases... let me dig up my favorite modshops service... ah here we go...
From gamefreax germany:
"There are several reasons for the ring of death to suddenly appear. With this repair we fix all the existing and currently known reasons. We make the following ammendmends to your Xbox360:
- remove the GPU's X-Clamp
- rebuild all solder contacts of the GPU
- clean and apply new cooling paste to the GPU
- install gpu heat sink with special screws and without X-Clamp to avoid unnecessary tension to the mainboard
- apply cooling pads to the four ram chips wich are thick enough to keep the ram chips in place (it is a known problem that the ram chips can shift due to overheating)
Allthough the repair is successfull on a long term in 95% of all cases, we are not able to give a long time warranty on this repair. If the problem should appear for a second time we do a second repair for free."
It costs 60 euros for the fix and x-clamp fix and 75 euros for that and a extra cooler... I got the extra cooler right when I had it moded just to be save...
