BDM NT fix deep bricked ECU411.
When you cannot get BDM ON mode and one possible reason is the device is in deep brick mode. The flash has been programmed the wrong firmware.
In order to fix this you need to disable the flash when hit detect. Pull CE pin high while hit detect. I used 150 ohm resistor connect VCC to CE pin when hit detect. After you see BDM ON, remove the resistor. Use command "flshdct code" to detect the flash and program the flash normally.
The same method works for MIPS JTAG device.

I do not have your unit. But if the CPU is MC683XX I can do something with it.
