How to set net id without a virgin dump.

This is the net id in the samsung NV RAM

31200000: 00 00 AA 24 00 00 00 00 00 00 00 00 A0 08 12 DC
start of nv ram --------------------------------net id ----- checksum

to work out the checksum get windows calculator up
click scientific mode
type in your net id
click hex
this is your net id
click word
click add
type 72D4
click =
this is the checksum for your net ID

examples

72D4 + A067 = 133B
72D4 + A009 = 12DD
(thanks to en4rab for working out the checksum)

connect jtag, power up box, fire up ocd commander, settings as wiggler, arm940T

type

byte 0x3120000C = $A0
byte 0x3120000D = $08
byte 0x3120000E = $12
byte 0x3120000F = $DC

replace the bytes with your net id and checksum
