ok to start off i ordered the nandx v3 and coolrunner vb to install to a phat 360 jasper. it was my first attempt so i practiced on a labtop first. i got really good at soldering wires but my problem seems to be the qsb. i ended up getting the e79 and keeping that board for practice. i have another 360 phat jasper but where i need to solder the nandx qsb i need to add solder to the mb. would it be fine to apply flux to the spot board iam soldering then tin the solder iron and when i add solder to the board put the tip of the iron in the hole in a fast motion to fill it?

Apply flux and then apply a small amount of solder to each point.... the QSB will be a lot easier to install if you do it this way.
Perhaps you could post a few pics of your soldering job. We could tell you what points to focus on
the one board that e79 i trashed i have not attempted on the other jasper yet. the holes i was going to apply a small amount of solder to would it be ok to but the tip of the soldering iron in the wole to fill it with solder then after all wholes are filled to place qsb down in place and solder it. also i figured once i did that i would make sure console boots to make sure i did not cause a problem there. i do use flux of course. i have been a mechanic since 2002 so i can weld just fine, just new to soldering.

i will also post some pics after i solder on the nandx qsb.

you don't need to put the tip in the hole you risk lifting the pad doing that. just add some flux to the point then get a small blob of solder on the iron and touch the point very briefly. the flux will fill the hole for you.
ok i will diffently practice that a bit more on the other 360 before i do it to the good jasper. i practiced the other way i have mentioned and did not lift pad and it fills hole quick. i just wanted to make sure that would not damage the pad.

This is what I do. Never fails me.
I clean/scratch the soldering point too. Even look it up under a microscope
Use also multimeter to test for joints and continuity before plugging the xbox. Test the qsb points and their corresponding points under the mobo.
Make sure you have a tiny (.5mm or smaller tip) and thin solder. This helps when working in such a tight spot.
Also, good lighting/magnifying eye works well too

i have all the tools a pro would have to solder the only thing i need to order is some solder wick or solder braid cause they don't sell in home deopo or radio shach in my area. the last time i attepmted to solder the qsb for the nandx it read the nand just fine but i ended up e79 the board.(this board was a best buy refurb so i could care less)
I use a 15 W Soldering iron.
I don't put the solder on the iron first but everyone have their own way =)
I put a tiny amount solder on the iron to get a better heat transfer tho.
Starting with applying some new solder to the holes, before putting on the QSB.
Then heat the points on the QSB and then apply soldier to the QSB points (Not against the iron) from the holes side. The solder flows down in the holes and will transfer heat to the boards points to prevent cold solder joints.
And flux flux flux

i think i good enough to solder the qsb to the board, but if i end up getting the e79 error will cleaning up the solder with some solder braid get rid of the e79 or will i have to have the console reflowed?
An e79 should not be a soldering issue and if anything you would get an E71 or 0022 error usually.
Jaspers should not need to be reflowed unless you managed to lift the solder underneath one of the BGA's.
I recommend thoroughly cleaning the pads with iso propyl and always to remember to apply flux to the points before you solder to them. Another tip I find is really useful for me is to try and get a tiny bit of 60/40 rosin core solder on to the point to begin the process and it helps with melting the original non leaded solder underneath for the through hole points.
