boot2 1.4.1571 maintenance menu won't let me delete OS

Hi, I've been trying to install nlaunch on my ti-nspire touchpad to run the CAS OS. I followed all of the instructions, I used nsNandMgr to install boot 1.4.1517, I put my OS upgrade in a folder called nlaunch under the name "phoenix.tns" but now I'm having a rather bizarre problem: when I go to the maintenance menu on my calculator in order to delete the OS, option 2 does not work. Hitting "2" will really just not do anything; It'll just leave me at the maintenance menu. The really weird thing is that all of the other maintenance menu options DO work, if I hit 4 to do a complete format, it'll bring me to a screen that says "press 1 to proceed." The problem seems to have started after I installed boot2 1.4.1571. Any way to fix this?
