Yes, you need to flash that firmware for the his to work. Why did you delete a line? Shouldn't need to touch it before flashing.I wasn't sure if I really need to try and roll my version back but I wanted to make sure and followed the instructions. I just received a replacement Maxx and it had Sys ver. 24.3.7, Android 4.4.4, SU6-7, on it. Anyway I downloaded the CFC-obakem_verizon-user-4.4.4-SU6-7-release-keys.xml.zip and removed the first line. While flashing RSD says "Failed flashing process. 7/17 flash system "system Img" ->USB error occurred while reading/writing. I need some ideas as to where to go now. Thanks.
UPDATE: I tried it again and RSD says 7/17 "system img" phone return fail
