vDubbzy wrote Try taking out the HDD. If that works then out it back in, get a USB, put a clean launch.ini on it, and boot it up that way.

If taking the HDD doesnt work than its not a plugin issue.

thanks that worked, the launch.ini was messed up. thanks

I had this exact issue, power on and count to 1 sec, then press eject. go to dashlaunch and remove your plugins. LOST is right, its either a plugin or wiring problem.

im having this same issue but mines is a plugin, im doing what you guys say but it still shuts off.
i don't want to erase everything in my hdd i have to many things.(the xbox boots fine with out the hdd).
anything i can do?

-LOST- wrote Hit the eject button on boot. It's most likely a plugin that's causing your console to shut off.

nvm it worked,May i say that i love you

Its been literally 1 month i don't boot up my rgh cause of this problem.I though there was no solution

your server files are probably not updated yet...

no my launch.ini was deleted from my hdd, so i had to put a default launch.ini on a flash drive and boot up. but i transfer the default to my hdd and now works perfectly
