The 220 coil is there for Hitachi xxDJ drives. For samsung drives you don't need it. THOUGH, one retailer suggests removing the 470 coil and replacing it with that 220 coil. Others suggest removing the coil and shorting the points.
As far as the LED function. I don't know what people are doing to get errors with it. I install an NME1.2 on a Samsung - it failed to work. I installed the LED function to see if the chip was activating, it was not. Then I found the remove 470 fix. All I did was remove 470. And the chip worked, and the LED would turn fof with a backup and stay on with an original.... So... take that for what its worth. But it was *NOT* a problem for me.
I would remove the 470 coil completely, then solder a wire between the two points. Test it. If it works, awesome, close it up. I'm pretty sure it will work. If it doesn't try putting the 220 coil in the 470 coils place.
As far as the NetworkOff feature, I dont know.
