How do you uninstall jj os off your mpc

I dont know if its the JJ OS but I cant even load my cf cards any more it just freezes.
If this is a jjos problem please let me know how to uninstall it.

check inside the cf card slot on your mpc, and check to see if any pins are bent/broken off.

the only way to do it is to load the original akai os from the cf card, and this will overwrite the jjos. perhaps the problem is with the cf cards, so maybe try a new one?

Since you can open .bin files with JJ OS, did you try to open the AKAI OS .bin from the loading screen from the HDD or CF Card?
