Hello everyone,
I've had this problem few months ago, I've had the official KitKat ROM 4.4.2 and then when the leaked Lollipop came out, I installed it and I didn't like it, I decided to install the unofficial frapeti's Cyanogenmod 12, it worked perfectly, but then I tried installing newer build of that ROM, but when I used TWRP 2.7.1.0, it kept telling me E: Unable to mount /system, so I used the old build a while now, but I decided to install the official Lollipop Firmware, however, when I used Odin, the installation fails when trying to install system.img. So it looks like there is something that stops from changing anything to the system as it stops in TWRP Recovery and also Odin.

P.S: I tried to use different USB Cable, different Windows, and different Odin versions.

Edit: I've just tried to install 4.4.2 KitKat back it tells me the same error, here are the logs:
