I'm having a similar problem, and I have a feeling it's related to the auto-update
No, it's nothing more than coincidence IMHO. You guys are all showing signs of E0102, and ssjdave80 even said he had the error.
Straight from the FAQ's::\ "0102 unknown error - though it's most likely GPU related literally means the console does not know what is wrong. possibly a short or cold solder joint somewhere. So far there is 1 major theory for what causes most of these errors is that the Ram, CPU, or GPU are not soldered properly to the mother board due either to poor manufacturing or excessive heat up and cool down cycles that stress, weaken and eventually break the soldered connection. This can be solved by re-Heating the chips DO NOT attempt this if your console is still under warranty. If your console is still under warranty return it to the store where it was purchased or call MS to have it replaced. I have also heard of limited success by simply switching the AV cable from "HDTV" mode to "TV" mode."
All of the problems you guys are describing are symptoms of this error. The most likely scenario is your ram, gpu, cpu are not soldered properly. You can try the heat gun fix: LOOK HERE or send it in to M$ if it's under warranty.

This should give you lots of info and help you get started. Good luck....

I think im gonna try to take it back to the store i got it from first, i doubt thats gonna work though. Would it be better to send it back or find other methods of fixxing it? I heard about a mod chip bypassing the problem, and if I went that route would I still be able to get on Live?
In your earlier post, you said that you got the console on April 22, your odds of getting a store to let you return your 360 would be very slim. There are alternate methods for fixing it (heat gun, thermal paste, etc.) but why do something that is not 100% guaranteed, as well as voiding your warranty? Sending it to M$ is your best option as you stated it was still under warranty. Even if it takes well over a week turnaround time, wouldn't it better to be patient and have a working console?
There is no modchip that will bypass the problems you are having, the only thing close to a modchip are the chips for the dvd firmware which will not solve any of your issues. And btw, you can still play on live with modified firmware / backed-up games, but no one knows if M$ is tracking this info or when / if they will start banning.
If it were me, I'd send it in, just MHO.....
