Pull all those banned consoles out from under your bed or from in your closet, because Microsoft just made one of the biggest mistakes they have ever done! Earlier this morning, on April 26th, Microsoft unbanned every single console that has ever been banned from Xbox Live. It is un certain if Microsoft has a backup of all the banned consoles but as for now, there are no signs of the consoles being rebanned. With the unbanning of all the KV's this means all your Jtags will be unbanned as well, however booting them will still result in a near instant ban! It would be clever if Microsoft did this to inspire the people deprived of PS3 to reuse the server, however this seems more like a human error. Regardless of the situation, someone is going to be in a lot of trouble for this one!
In order to do this you are going to need to take your banned console and plug it into live, then you are going to have to manually update your dash using this file http://www.thetechgame.com/Downloads/id=2167.html
. Simply put that on the root of a USB stick and reboot the console, it should automatically start installing the update.
