did you get a backup of the modem or the one you are trying to clone?

when you say brick you get no lights right?
can you read the device?

you can do this
Rescue SB5120. When box not fire up. Normal programming will not work. First need to program boot. No watchdog exist in this case
detect
ldram boot (Select proper boot file)
erase boot
sprogram boot (Slow programming)
reset
detect
ldram image0(Any tabes you have backed up)
program image0(Any tabs you want at normal speed)

or

what worked for me was to
just write a good full flash backup back to the box. and it was good to go.

Forget the erase boot part
do
sprogram boot

Looks like it does not get detect reliable. Try to use command
"trap c"
"trap a ffffffff"
See if you get DEBUG ON.
Then detect and "erase" and "sprogram" the boot.

dont think he was looking for help just giving advice. he was saying he has a similar modem.And for op to try the lowest settings cuz it worked for him.

but i could be wrong

Well After Reading again soinds Like Both. He Suggest to Lower Speed While he adds that his is a DCM202 with Same Problem. Never mentioned that He Got it Fixed.
