In order to flash your ASUS Zenfone 3 ZE520KL you need to check out either your device is using MTK (the firmware name should contain "MT") or Qualcomm chipset(the firmware name should contain "MSM"). In the case of MTK, you need to use the SP Flash tool to flash the software.

If the firmware is in the RAW format you need to use the special flasher. You can download Asus Flash Tool v1.0.0.24 here.
