Samsung DA E670 or E750 stuck in demo mode
I purchased some Samsung da models in an auction. I'm thinking they are in demo mode because only the 3.5 mm aux input works. I can't seem to find the reset code. Could anyone help? I also have a few LG audio docks that pretty much were in the same condition. They did show an LED that they were in Aux mode. I tried finding unlock code for them on the Internet with no luck. I actually found a sticker on the back that had the unlock code and sure enough it reset them and they are in normal now. I am thinking that this some top secret info, but not sure why. Can anyone help?
