IIRC you need to program both the RX and TX frequencies into memory just as if it was an odd-split pair.

After the mod I do not seem to be able to get to any of the extended frequencies. I also am unable to transmit on 60 meters.
Is there something I need to do in the menus to open up the additional frequencies after the mod?
I did the mod by removing 2-3 and adding 6 and 7-8-9.
I reset as indicated <func>, V/M and power until it beeped and then powered off again.
I thought everything was fine but now I cannot tune below 430 or above 439 in 70cm band.
Do I need to reset some menu option or something to at least get 420-450 in that band.
Of course I expected to get up to 470, which of course is not working.
And as far as I can tell none of the extended freqs are available to me after the mod.
Any ideas?

Do the reset again just for the heck of it. If that doesn't do the trick, make sure the jumpers that are supposed to be removed are clear of any stray solder. Use a magnifying glass or readers if needed. Something like you're describing usually is caused by a jumper that is still connected.
I double-checked the jumpers and as per your picture and the Yaesu numbering scheme Captain, I had jumpered (I thought) 7-8-9 and 6 and removed 1-2. I used the strictly left to right numbering scheme when I referred to them before, but anyway I did at least do the right ones... 
What do I mean by that "I thought"? Well I used the circuit writer pen method of jumpering them and used a soldering iron to remove 1-2. I checked that 1-2 had no connection using a multimeter which showed no connection there which I was pleased with.
But then when I checked the *jumpered* 6 and 7-8-9... Well they also showed no connection... what?!?
I mean I could see the dried silver and the tips of the probes right there on a solid coating of the stuff and still no reading on any but one. I believe it was jumper 8 had a reading but still showed some resistance... Which considering how close it was actually was amazing to me that I could still see resistance.
So now I can clean that stuff off and re-do it or after cleaning just do it the right way and use solder.
Is that what you guys would do? I mean use a soldering iron and melt the jumpers together?
Or do you think I just flubbed the circuit writer method somehow?
I do have an iron with a pencil tip (50 watt) soldering station made by velleman but those jumpers are so small... man.
I should have checked for good connections when I first did this but again, such a small area and they were clean and so forth... oh well live and learn.
So what it boils down to is that the radio probably only saw 3 changes, the missing 1-2 jumper and the new 8 jumper since none of the others showed a good connection.

Thanks Mudfoot, but I am too impatient to bother anyone with this kind of thing.
And I must say my fear of doing this soldering was a little unfounded. It was actually not bad at all.
I did the work checking each jumper as I went and voila! Every one was showing good connection.
That is the *very* last time I try any of that circuit writer stuff.
So I checked every band to include 420-469.999.90 and they all work as expected.
Hot dog!
Thanks guys for the help.
And just to recap what I actually did on this brand new Yaesu 857D (purchased 8-22-2016) was to unsolder the jumpers 1 and 2 as per the picture provided by Captain Kilowatt earlier. And note that I am using the Yaesu numbering scheme as also denoted in the Captains excellent picture.
And then soldered jumpers 6, 7, 8 and 9.
I then did a complete reset holding the <Func>, <V/M> keys while powering on the radio and holding all of them until it then powered off.
After then powering it back on, I had all bands opened up.

Radio designs are always changing. They try hard to make it hard for you the user to open the radio up for expanded RX/TX. Glad you got it resolved and good deal posting up the photos as well. If you have any parts radios laying around they can be great tools for learning to solder as well. Not saying you don't know how to. Just saying its easier to mess up a parts radio that is already broken than your brand new radio. Having the place you purchase the radio from do the conversion is worth the extra little bit of money at times!!! It keeps you from frying your radio and makes the place you bought it from responsible for any damage they might cause!! Just some food for thought. Again, this is not to say in any way you or anyone else can't solder. It's just less BS to deal with at times. Glad you got it resolved. Have fun with it!!

DEAR FRIENDS
I HAVE READ ALL YOUR COMMENTS AND SOME UNSOLDER JUMPERS 1 AND 2, AND SOME DID NOT
DEFINETIVELY, CAN SOMEBODY TELL ME IF THE JUMPERS 1-2 HAVE TO BE REMOVED?
MY 857D IS A NEW (SEPT 2016) USA VERSION, TYPE A2, SERIAL X000RZJKXR

I did mine in Aug of last year. I put in all the details of what I did. I would do if I were you since you have a new rig.
