Error when flashing android 5.0 topic

Hey guys my problem is that when I try to flash the android 5.0 build with the recovery flash from SD tool, it gives the error: 3c_main.apk has unexpected contents
This is bugging the **** out of me and I'm stuck on 4.4 after reverting from a rooted 5.0
I attempted to install with stock recovery and stock firmware.
