usbbdm,
my WRT54gV8 is bricked so bad after trying to load dd-wt fm, all 5 lights from right to left are up.
i'm using usbjtag 0.30v and i'm only getting:
detect
IDCODE 2535417F
Broadcom Part NotFound 5354
IMPCODE 810904
DMA supoorted

In your prev post you said "USB JTAG NT is the solution. The old USB JTAG has issue when detect and since clone exist, no more fixes for the clone"

But, is any way to debrick this sh**t with 0.30 Licensed version?
maybe a good def file will help?

There is some luck you can do. 3.3V is one solution for old USB JTAG. It is possible but very hard.
The detect lockup is the problem so you need to do a lot of unplug/power off/on to get out of the state.
Def file will not do any help in debricking the router.
The method used in NT is to stop the CPU at bootup and you have full control. The clone is all it does to stop the development of old USB JTAG. The time spent on debrick V8 with old USB JTAG will be much longer than NT. All I am saying is possible but harder and longer.

USB JTAG NT software was based on USB JTAG.
0.01 of NT equals to 0.31 of USB JTAG.You can see how much the NT has been enhanced.

You need to put the DEBUG ON state and then erase the cfe. Then sprogram the cfe.

I would have to take a look to determin what is the problem.
If you can detect without DEBUG ON you should be able to erase the CFE and program the good CFE into it.
