Don't worry 'bout me that much rigger66

I don't want to remove current wiring until I would be completely sure that I'm doing right with the software part so then it's 100% a bad soldering/wiring. At least not until I get bat41 diodes so I would rewire the simplest way.
Current questions for me are:
1. Is coolshrimp's jtag tool is fine for uploading xell with smc fixes for boxaddr transistor jtag?
The tool gives three options: original smc, aud clamp, aud clamp and tray.
As I understand there are two signals used for transistor jtag in the tutorial here on xbox-scene: the db1f1 and aud_clamp (of four available: tray (dvd pwr), argon (rf), db1f1 (hdmi?), q2n1 (aud_clamp) as stated in smc_io docs).
So if I use q2n1 and db1f1 then what should I specify in coolshrip's tool?
aud_clamp only? what about
db1f1 then?
I mean what the heck with the jtag tool.
Here is an application where you can
set each point to use for each wire including db1f1 (check the
shot) That's what I'm gonna try next time for getting right SMC.
2. If I do everything right (using 'aud clamp only' in jtag tool) then there is a possibility that db1f1 wiring is fu*cked and that's why I get E79.
As I stated before the point just pulled out with 1mm of the track... then I tried to solder that wire to alt point FT1U2 - it's much bigger and easier to solder. I can't understand why they use that db1f1. But got E79 too.
Then I soldered it right to the track of db1f1 (some people did that and got everything working). But still E79.
That's the cool-story.
3. Stock NaND boots fine. Is it okay that it boots fine with soldered jtag wiring on falcon or that means my jtag wiring is bad?
And what if I stop using db1f1 and get the wire to any other jtag point (tray or argon) and set the right smc. Would that be okay? Or they can replace aud_clamp only?
Do I really get the wires to points specified in tutorials?
Or can I solder any of the wires from any transistors to any jtag point and just generate my right smc?
Anyway I'm thinking of getting few diodes and doing diode jtag, it's much simpler to do and people tell that it works like charm... not sure about screwed trace under motherboard though lol...
rigger66, ty for your replies.
