Just replaced my MPC2000 with the MPC2500 lovin it so far. The 2500 came with JJ OS1 ver. 5.46. I'm tryin to undestand how to upgrade to XL. Do I have to downgrade first or do i just pay for XL and install all the links i found are confusing... any help is appreciated.

Cheers

Just download latest xl, load it up thru normal loading from drive like sample. After powering on again go to save mode and u will get a code there, jj will know you already have os 1 so you will get a discount, just follow the steps on site.
