Bluetooth game controller: not working anymore

I own my Minix u1 for just a few days, but my bluetooth Ipega game controller was one of the easiest parts of it

The connection was easy and fast. And it worked at a decent distance from the unit

Then i hit "update"

And now it juat wont work

1) now Minix only recognize the game controller if i get it REAL CLOSE to the unit. Like, put both touching eachother

2) minix just cant pair with the bluetooth controller. Why? Because it keeps asking me to input a numeric code into it. Its a game...
