jjos and replacement part

Hello,
i have a problem.
after a concert, my 2500 was broken on the rear, the 2 digital connections are broken, and a part of the mother board, and the data encoder. since i have a lot of noise,i find a motherboard but i would like to keep my jjos license. where exactly the serial number and os are?? what parts can i change without lost my license??
thanks

I assume it's stored somewhere in the flash ROM on the motherboard (so don't change the motherboard).

arf, that's exactly the main problem
is it possible to unsolder the part?

Drop JJ a mail and explain your situation. Customer support was always top notch with him.

I think i had read somewhere that if you change part you have to purschased a new password. I will send an email to him and tell you.
