How can I break my xbox 360 without xbox knowing?
How do you know someone from Microsoft won’t read this, figure out your IP address and end up charging you with fraud, if you ultimately do this… Anyway it sounds like either it’s going into the wrong video mode, or it’s broken already. If the video really doesn’t work, it should already be Microsoft’s responsibility to fix it, there’s no reason to break it any more. If it’s not breaking no matter how you abuse it, you’ve probably got one of the newer versions with 2 heatsinks. Don’t waste your good luck, just get the video fixed if needed, and keep it. You already know it resists the RROD and will probably last, a replacement might not.
Okay this is how I did mine with great success BUT VERY DANGEROUS. I turned box off left power cable plugged in the wall…then detached power cable in half right by the brick. Then have other end hooked up to the xbox. Sit the xbox up vertically so that it is very easy to pour water, yes water, into the xbox. I had to pour maybe a cup into my xbox but I am not sure what would work better because I also shot water from a bottle into the dvd drive until you see the ring of death…Then unplug your xbox for a few hours to let the water evaporate and test the results. If no more RROD occurs then repeat the process. Good luck and this worked for me undetectable by Microsoft.
