Rooted Motorola Defy Mini with KingRoot and the tried to install OS Kitkat 4.4.4 no success

[AC Question]

I rooted the phone with Kingroot then I restarted the phone in recovery, and proceeded to do a “Factory Data Reset”, “Wipe Cache Partition” etc.
then selected "install from SD Card"
I then chose Recovery kit first, and confirmed the selection with camera button on side and the recovery kit failed to install due to signature,
then chose the ROM kit, confirmed the selection the selection with camera button on side and then the ROM failed due to signature,
then choose the GApps kit and confirm the selection the selection with camera button on side the GApps kit failed due to signature,
then last of all I “Reboot System" Back to Normal.
The phone was with Optus Australia but phone has been unlocked.
Please help as I need links for the Software & Kitkat 4.4.4 Custom ROM.

I have tried CM11 Kitkat 4.4 Nightly but no success.
