I may be back in the HB dna 40 game again..I ran across a vendor running a pre-order for units with corrected wiring (stated by vendor on ECR) straight from Hcigar..
I did find it interesting that one of the pics showing that the ground issue will be addressed looks kinda familiar..
I'll have to think about it.. If anything, just throwing this out there for folks. Be SURE to read and understand the vendor's policies before making a purchase. Contact them with ANY questions before ordering.. Here's the link:
HCigar HB-DNA40 - Smog Distribution
Clicked on the picture showing the internals shown in the Smog link and their picture opened up and this was stated: "Revised wiring (fixes Weak Battery issue on the beta model) No hot glue!"...... so the first run was a beta version???? and the consumers once again were the beta testers....sound familiar?????

You've been around here a couple of months longer than me.. We've seen it for years...
I was just wow'ed by the clean wiring job / genuine DNA 40 originally, and let my good judgment go out the window on this one at first. I just thought "what could they possibly screw up on this?" Well...... TBH, I still have some reservations.. But, the price is certainly right... But, what if.. Damnit! It's still tempting.

Yep.... understand where you are coming from....a lot of history behind us.....and vaping moves quickly...reservations me too...nuff said.... not gonna "get in the weeds" here.... have a great day....
Are you following me? j/k
This is where I originally had heard of the HCigar device and I was interested. But when SV got them in stock, I decided to jump on it. I'm curious if they will address all of the issues or not. If you look at their product page, you'll notice that they are planning for a Round 2 of these at some point in the future. But I think it will depend on HCigar acquiring more DNA40 chips. I hate to admit it, I'm tempted to get another. Although Round 2 sounds better to me. My fear would be that a Round 2 doesn't materialize. I guess I'll have to think about it. So off to work I go.
DAMN! I was just getting ready to go out, and UPS dropped off the Hana Modz V4D dual 18650 I ordered the other day.. One problem.. It's a V3 DNA 40 SINGLE 18650 in the box.. 
Goes to show there could be problems no matter where the mod is coming from.. I was at least able to phone Hana Modz and get a return shipping label. Just jerks my chain that I have to wait until this one goes back to have the correct one sent.. I was told that they still have a blem V4D Gunmetal in stock, and are holding it for me..
Hopefully, my luck will run better if I decide to go ahead and order the HB DNA 40 again....

Sorry to hear about your Hana mess up. Glad to hear they are promptly assisting you.
I'm a glutton for punishment. I just ordered a second HB DNA40. Not sure if I'll crack the 2nd open, but I'm interested in the changes made.
Could not some super glue do the trick for that spinning 510? I mean, whit the warranty already voided, some glue or silicon can`t do any harm? Look at other devices, they are so full off glue, you would not believe it if you did not see it
I would like to know if anyone would agree with this as I have one of these coming tomorrow. I am good to go on fixing the ground from battery to B but interested with the above. Would the glue cause any issues on the 510???
Thanks everyone for a great thread and all the info to help each other out.

Got my battery ground fixed today gratis by a very nice MVP-vaping tv repair guy. Looked at the 510 connector and could not get it to spin. Felt it spin the first three or four times I put a tank on it, but nothing today when I tried to get it to spin. I'll keep an eye on it.
Mine is still working today. So that's a good sign. Here are some pics from the "fix". Disclaimer: This is just a picture show of what I did. Do what ever you want to your own devices at your own risk. All I know for now is that my wire is replaced and it still turns on. I know for sure I could have done a better job, and I don't even know if I did it correctly. I may have to go back in and tweak the final solder point.
1. Remove screw from the bottom and slide out the negative battery terminal. It easily slides out if you have small fingers.
2. Remove old wire from battery terminal by heating up the existing solder on the battery terminal and carefully pull the existing wire off.
3. Get a piece of 20 or 22 gauge wire and solder it to the battery terminal (I used 20 gauge). Use a piece that is longer than you need. I added a little bit of new solder after attempting to attach it to the existing solder.
4. Still with the new wire not attached to the device yet, cut the new wire down to size, estimating enough length to reach the -B- pin and for the battery terminal to slide back into it's guides. Insert the exposed wire down in the empty -B- pin hole and attempt to solder it into place. Like I said, I accidentally bridged the two pins here. From what another poster says, it probably doesn't matter, but I don't like it because it looks horrible and it bothers my OCD. After looking at the pic, it appears that I didn't get enough solder on the right side of the pin, so I may go back in and fix that. The old wire is only there for reference.
Genghis, very good instructions, great pics, and nice to see you put the wire through the hole in the pcb. Those pads don't take solder easily, they must be a lead-free finish, plus the pad size is tiny, they are not easy to solder.
I can't see how you'd secure it with Superglue. The 510 center pin is supposed to be able to move up and down as the atomizer is screwed in and out. How do you suppose it will move if you superglue it to the housing?
Not being able to cape at 40watts in tp mode and a 510 that will fail seems to indicate that no it's not a reliable device

Since the day of release. Issues right out of the box. Not board issues but wiring issues. My post 252 on this thread lists all issues I ran into and I'm not the only one
here's a weird thing. When my battery was grounded to the case I got an accurate battery indicator reading. Now that I have it wired properly, my battery reads what I think it should when it wakes from sleep, but after I press the fire button the battery indicator jumps to like 75% full and stays there until the next sleep. This is consistent with what a lot of owners say about a variety of DNA 40 devices, but in my case when the box was improperly wired my battery indicator worked as you would expect.
I wonder if the setup where a wire is run from the original case ground to -B- on the board maintains proper wiring while keeping the battery indicator function intact. I would love to hear from all Hcigar DNA 40 owners on this.
Is your Hcigar DNA 40
A. original wiring
B. rewired to Evolv specs
C. rewired using a jumper from the case ground to -B-
Is your battery indicator
A. displaying correct battery discharge level
B. not displaying correct battery discharge level
I was A-A and after rewiring am B-B

does the DNA 40 battery indicator drop onscreen during fire depress and then rise back to previous level when fire is released the way that Yihi chips do?
In any event, my rewired DNA 40 does not display a battery level drop when the fire button is depressed, and I can't for the life of me remember how it functioned before the rewire.

also, I am going to keep an eye on my battery discharge with this battery to be sure that it isn't an incorrect level after waking from sleep that is confusing me
it takes a while to drain a 25r, so if after I vape this some more if it appears that I'm mistaken and the chip is showing battery drain correctly I'll post so

You know that is a very good point and I really didn't think about that at first, I don't have my box in front of me yet. Hopefully someone figures out something or does a full 510 swap soon.

Ahhh, so this is your first DNA40 device? The battery meter leaves a lot to be desired. I have 2 DNA40 devices and the battery meters on both only show something that relates to battery voltage after the unit wakes up (after the splash screen), and once you hit the fire button its all over. Sometimes I pull the battery and refit it just to see where the battery is at (force a reset and splash screen).
ETA - no the DNA 40 battery indicator does not drop onscreen during a fire depress on my units.

This is my first DNA 40 mod. Bought it from Sweet Vapes the first day it was released.
Was extremely disappointed to see the issues with the wiring. However, HCigar did a very clean job on the wiring.
I rewired mine by just bridging, the existing ground screw to the open board hole. I hadn't even fired it off before and probably didn't need to do this since I don't push my devices, but didn't want any issues. Will probably attach an atty and try it tomorrow. Haven't fired it up yet.
I'm planning on using a SubTank-mini with the Ni coils, so we'll see how it goes. I'm not the neatest when it comes to soldering, but I think I have a good connection now to the board and the device fires up fine. I used solid copper wire (22 GA), and had a really nice fit before I soldered it. If nothing else, it has to be better than before.
This will be my first temp controlled device, so I'm ready to give it a try.
I'm installed/removed several atty's to it and my 510 connector only turns a bit if at all. I'll fire it up probably tomorrow and worry about the 510 later. I always carry an iStick with me as a backup so not worried about being able to vaoe.
Bigger question is, what happens if the 510 wire dumps? Does it short out the device, shock you. overheat, etc? I was just planning on using it until I had a failure from the 510.
Thanks folks
