sb5101 cert copy

[cheeto]

Hi folks,
I have an sb5101. And it's been a while since I last used my usbjtag.

My questions:

To copy from a stock SB5101 (supplied by local cable company) i must:
open usbjtag
and enter these commands:

getram cfg
save cfg

hook up my personal modem, I must enter:
ldram cfg (select extracted cfg.bin)
program cfg

is that correct?

I did this but my modem is not cloning. What I noticed is that even after i program the cfg.bin file onto my modem, my mac address in Haxorware doesn't change, even if I press COPY FROM CERTIFICATE button

Any idea on what could be wrong?

Thanks guys!!
