My storage is untenable

[lichborn]

My sysI have a lg optimus f3 from virgin mobile and it seems like after about a week im going to have to go get a new phone. As i said i bought this about a week ago and have rooted it . TheI liked the phone alot... then i found out about itsstorage issues. Turns out its the system partition that is to blame and now that i know what i have to fix i cant cause every time i try installing a file manager with root access that could delete files at that level it says i dont have enough space. Please help me, Android Central, your my only hope.
