So. Yeah. It is kinda fixed. Really. needs soldering to get unfixed again.

Was hoping pictures from yours will reveal other methods. :)
This one is picture from my "adapter" :D

Here are some pictures.

Nb. I don't want to open the device because it's an extremely rare proto device.

Thanks for the pictures :)
Does the adapter come off? Or is it fixed on device?

Adapter is fixed on device. It comes attached to device.
Jtag is only for debugging right? Isn't same as rs232...
Where can I connect it? On what hardware? Without Lauterbach...
What software can i use for it? Any idea...
If you can explain me in details please.

You can (i suppose, i dont have this) use the jtag to directly program the flash chip. Say, recover from even the worst hard-brick, since you direvtly connect to the NAND.
Yes, you need a jtag programmer, and soft. Something like this http://www.modularcircuits.com/blog/...ag-programmer/

You usually use the software that came with the JTAG adapter. This can be vendor specific.

But for this one I have what software and hw I can use? You have an idea...

I think you need Phoenix service software and possible some box that connects your jtag/pc/Phoenix altogether

Where can I find good box to connect jtag n9? Is my jtag connector is a mictor 38 connector?
Is usb port to jtag will work with my device? And with phoenix service software.

Edit: Is this one compatible?

Edit2: How can I use phoenix service software with a jtag mictor 38 pins? Is there any tuto please?
