Earlier i updated my Asus ZenFone 4 (A400cg) from kitkat 4.4.2 to lollipop by downloading firmware from asus official site, UL-ASUS_T00I-WW-7.3.3.0-user.
i placed the file in the root directory and after the update the memory took by the file (780 mb) didn't clear up, i tried clean master and it was not able to free that space.
