mine started to freeze exactly aftre the update... but ok, It´s seems to be just a coincidence.
So I opened the 360, and there were the paste spilled out. I cleaned it and so I just replaced these paste for a white ceramic paste wich I had in the moment...
So I turned on the console, and so it just were as before, feezing on start-up, other time on the dashboard, just a couple of minutes after boot up. And so the damn Ring Of Death again.
I turned off the 360 and goes out to solve some personal problems,...
few hours after, I came back and turned on the 360 once again, and so surprise.
The console were fine, I played such 1 hour of GRAW fine without freezes.
Then I turned off just to be sure about, and when I restarted it, once again Ring of Death.
Then I purchased the ArctiClean and Arctic Silver 5 to do everything again,.. maybe were the ceramic paste I´ve used wich just worked fine for a hour.
So there was another try with ArcticSilver 5... this time I got the Red Circles of Death right in the face, and now the console seems not to boot anyway, and by the noiseless, the fans seems to be weak.

Please, someone can help me? What the hell I could do now?
The error I´m facing still is 0102.
I sell video-games here in Brazil, and always has supported the Xbox at war against over these PShit 2 consoles, but this time, I´m sad to feel such M$ is betraying us with this fucking nice killer console, but full of glintchs.
You noticed how quiet than fans are too? I noticed that when mine started screwing up. They are not as loud as when they were when I first got it. Like their is a voltage problem or the temperature sensor for the fan speed is screwed up or something.
