Hi, I'm from Brazil, so I'm sorry for my bad english
Two weeks ago, I bought my Xbox Slim 4gb with Kinect and 1 controller.
Last week, I bought three new officials controllers. I tried to sync them, they sync but 1 second later they turn off.
I tried everything. I went back in the shop, I reported the problem that was happening and they tested and also failed. So they tested a new Xbox, and succeeded.
Everything worked perfectly. And gave me the new Xbox. I got home and tested it and everything worked. So the Xbox ask me to update.
Once updated, did not work anymore. It only works one that came with the console, three new controllers no longer work, the same thing happens, connect, i can move for 1 second and disconnects.
I don't know what I do.
Help me please!
