what version of dmt tool is that?, are you a 100% positive it a BC chipset?
v8.07. and yes 150% positive its a Broadcom Chipset Router/modem

here are the details of the routers CPU info.
system type : 96358VW2
processor : 0
cpu model : BCM6358 V1.0
BogoMIPS : 299.00 (300mhz Cpu Possibly

)
wait instruction : no
microsecond timers : yes
tlb_entries : 32
extra interrupt vector : no
hardware watchpoint : no
ASEs implemented :
VCED exceptions : not available
VCEI exceptions : not available
unaligned exceptions : 1396786
As you can see it uses the BCM6358 *BCM = Broadcom*

DMT Tool info
adslctl version 1.0
ADSL PHY: AnnexA version - A2pB023k.d20k_rc2
System Type: 96358VW2
Uses 60meg onboard memory.
i also think the 3300v2 has 16meg onboard flashrom.
and finaly more researching i have found out that the dgnd3500 is not a Broadcom chipset router. so if anyone gets that router and is into lower SNR tweaking and modable firmware`s ect then forget it

lol
