GP900-99 ( MT6000E ) display hack

Hi!

I have GP900-99 whitch is a nice radio but Motorola did a funny thing with channel alias.
You can only assign number 0-2 for the first four segments and 0-9 for the last two.
So impossible to assign frequency ( like 145500 ) to the channel.
I did some hex editing in the .odb file to change 0-2 option to 0-9 but not much luck.

This is the top display on the GP900-99:

After hex editing it show 0-9 but won´t take numbers 3-9

Maybe someone with more experience in hex editing can help me ?!
