Vlad,
Here is what I got...
This is Sam. It is odd that the user was not able to update the firmware of the LCD box.
One think I can think of, which should not be a problem is that a kind of LCD program box he has. If he has a formal program box, " 2 in 1 LCD professional program box", it may have a gritch. we recommend to upgrade it to the latest LCD program box. this program has a bigger memories and many features were improved.
