downgrade phone to android 8 firmware ( nd1-5xxx )

[smartgsm.cl]

Hi, i recently bought credits for Ntool. I'm new working with Nokia HMD. How is the process to downgrade Nokia 5 ND1 from Android Pie to Oreo? I downloaded android 8 firmware ( nd1-5xxx ). What's next? just flashing normally?

Thanks in advance
