To write QCN file, you need to activate diag mode. Root first and then run this command :
adb shell
su
setprop sys.usb.config diag,adb
But since redmi note 3 Special Edition Kate need bootloader unlock to root and not support enable diag via code, so you need BST Dongle to easily enable diag without root and just one click enable QC Diag button on BST software.

and check in device manager, diagnostic port must exist.

You can use QPST, QFIL or UFI androidtoolbox to write qcn file.
