Pls Help sb4200 BCM3345KPB

[gers1980]

Hi

Im about to flash my modem but would really appreciate a couple of answers before I start.

I have a sb4200 BCM3345KPB chipset.

1. So far all I see mentioned is the BCM3349 chipset. Can my modem be flashed?? And if so what firmware rev should I use.

2. I have been reading that I may need my original cert from my modem. Can any one shed some light on this pls.

Im not a complete noob, ive done a load of ambits.

So any help with the sb4200 would be great.

Thanks
