LG Fusic / LX-550

I have the LG Fusic LX550. I've used programs like QPST and Bitpim only to preview folders and documents in the phone. Is there anyway I can unlock the nvm folder using ASC write program or any other program? I already have my MSL # im just looking to unlock the NVM so I can manually add .jad and .jar programs. I've read through a lot of forums and threads only to find tutorial on editing nvm folders on other phones. Any way to unlock the nvm of the fusic specifically??? 😳
