Wassup everybody,

I'm new to JJ OS128XL, I come from the 2KXL and recently bought a 2500 with OS128XL ver. 1.69 installed.

On the page below I just found out that a more updated version of OS128XL (2.18) is available and would like to upgrade, could you please explain if I need to purchase another password or if I just need to copy the file to my CF and load it.

Thanks in advance,

Pez
