Aron Bezzina's video: NEC SV8100 Failed Fermware

Last week I was given an NEC SV8100 Phone System. It was in great working order, I factory reset it then I decided I should update it. That was a bad idea lol. I found some firmware online and uploaded it via the web GUI. I figured it would throw an error if there was a problem with the file. It appeared to like the firmware, it updated and rebooted. When it booted back up the phones didn't work and I had LEDs flashing indicating an error. It appears as though I still have the ability to change the firmware via the USB port on the front. I hope if I can get the proper Australian firmware I can flash the unit with it via the USB port and have it work again. If you can help with this please let me know. Thank You :)
