ROM's C and D didn't work because they're AOSP ROMs, and 4.4. You can't cross versions. Besides that, I'd get the safestrap 3.65 APK from our own safestrap thread to make sure you get the correct JFLTEATT version and the MF3 kernel modules which you need to flash after every ROM. What exactly is your process for flashing, and what slot are you flashing to?
