If you programmed wrong firmware you will likely get in this state.
If you use USB JTAG (NT) and cannot detect the flash you need to debrick the modem.
Try to program the modem withg UJmodem will make less mistake.

IF boot is wrong, use sprogram the right boot and then power off/on the modem use program to program the rest of the firmware should bring the modem back to life.

Both app should have those commands.
If your modem is bricked you need to use erase and sprogram to program the boot. Or use init sequence then you can directly use fast programming.

sorry for long delay in response on what is going on with this modem. that method did work far as debrick, all lights comes on. but however the pc/activity light doesn't come on at all.

If the PC activity light doesn't comes on maybe It's because you have your Ethernet port disable. It doesn't matter if you was able to JTAG the Modem and load a new Firmware. The modem will work but you won't be able to connect until you enable your LAN. (That is possible if you forgot that detail) Also, It is possible that your LAN cable It's in bad condition, try with another one and see what happens...
