Installing fvdw-sl firmware on Lacie 5Big Network

I have a Lacie 5Big network V1. I want to install the fvdw firmware on it but I have some problems. I made a donation of €20 and have downloaded fvdw-sl-console-6-18-1-v2-29jul2019-32bits.part1.rar. I tried to run the console but I am asked for a password. I have also downloaded spd8020-first-time-install-package-13feb14.part01.rar but it is asking for a new volume. Is this one of the disks from the 5Big? I have also downloaded install_fvdw_sl_firmware_hlp.zip and read it thoroughly and attempted to follow the instructions but to no avail and am still none the wiser about how I am to install the firmware on my 5Big. Can anyone give me a clear set of instructions on how to install the firmware and configure my 5Big please.
