Step 2: Make sure that your phone isn't connected to your PC via USB, because its some times prevent phone from entering fastboot mode correctly.
Step 3: Press VOL+ & Power Button. until you see Fastboot logo. it should be like this picture.

Note: Some times it ask to confirm if it's your first time to unlock it if you came from Color OS version.
you can use volume buttons to choose between menus and choose yes & Power button for confirm.
Step 4: Connect your phone to pc.
Step 5: In folder that you downloaded in first step you will find a file called Bootloader Unlock just press it & press any key on your keyboard to begin unlock your boot loader.
Step 6: Your phone will restart after unlock. Power it off again & Do Steps 2,3,4 again.
Step 7: You will Notice that there is others two files in folder:
Install Rom 16GB = for 16gb phone.
Install Rom 64GB = for 64gb phone.
just open it, press any key, it will start installing new rom for you & lock your bootloader again.
Notice: When downloading using google chrome, maybe a warning message appears to you, this because folder contain .bat files. it's completley safe
WHY I SHOULD USE THIS WAY !!
- if you have chinese version (Color OS) & want to make it 100% Original cyanogen.
- if you device is bricked or bootloop and can't make it work again.
- if you facing errors after OTA update.
- if your version is too old & want to install latest one without install any previous update.
- if you facing wi-fi issue or connection problem.
** this way install a complete rom from A-Z including stock recovery, modem, boot image, etc.....
