Ahem. You haven't made any kind of a convincing argument as to why anyone should ever want to do it that way. Look - here is a really big clue already posted by somebody else, which I found at the end of the thread you just directed us to:

Now applying a little common sense here...
If you don't solder the Tri-State there is no way to maintain that electrical connection on a permanment basis. Only a temporary one. So you're not going to benefit from such PERMANMENT attachment to control SBE through your flasher device. Not just with E3 mentioned there... also the Teensy has a similar connection pin for assuming programmatic control over TriState. This is a very useful feature and for such little effort... Well does that answer your question?
Avoiding that small step (by using tape and not soldering to the Tri-State) only really makes sense if you already knew beforehand that you intend to immediately remove the flasher right after downgrading. "Downgrade Service". I cannot imagine any other logical or sane reason.
Or would it work without putting ps3 back together? like put most of everything together like fan etc. just not completely(Less risk of tape tearing or moving)
And exactly how else were you planning to ensure that the tape doesn't come off during flashing?
Look - if you want to gain a better understanding for what's involved:
It is pretty easy to open / take apart your PS3 to get familiar with its internals and layout way before actually downgrading. You don't have to entirely dissassemble it. But can still get a much better hands-on understanding of how to deal with the major components, yet without going quite so far as removing the heatsink(s) etc.
