erasing and uninstalling

please help i need to do both before my warrenty runs out

If you mean returning the MPC to its original OS, then you can just reinstall it. Download the Akai OS from the Akai website and load it up it the same way you installed JJOS.

This will erase all of your flash memory too.

thanks, so this will erase any trace of jj because the guy said that it will void the warrnty

Forgot to say, you can also restore your MPC to its factory default:

"Reset the MPC to factory defaults: Turn off your MPC, hold [ERASE], turn it on." (This is in the FAQ)

But I guess either will be fine!

not to be a pain in the ass but the erase and turn it on thing did nothing and i dont know how to install a new os.

Did you try:
http://www.akaipro.com/mpc2500 - click Docs & Downloads, you'll find the instructions there. Well, if you have an MPC2500, that is. I guess you'll find instructions for MPC1000 in the relevant section. It's not that hard, really.

Did you read my first post? With two links telling you how to do it?
