I had same prob & sum1 sold me an SD card with a fix for my problem already on the card. I also received very detailed instructions which I needed because I'm really not that good with computers. I guess I could forward the card onto you if you'd be willing to buy it? before I tried this I had been searching on this site for anything that would help me for a month and a half with absolutely no luck. so needless to say when this worked I was more than excited it also updated my 900 BT 2 version 4.1 whatever that means? anyway send me an email if you are interested @ ryansphone55@gmail.com
