new dna40 no "lock atty"?

[nic_fix]

I got a brass hana a few days ago. it does not say lock atty when I hold up/down in temp mode. I called hana. they informed me that all the brass ones have the latest revision of the chip and there are no updates available now. to be sure i called the store where I got it. he said he has many dna40 devices he is sure are new and they do not say that. did they then remove that at some point? so is this the latest revision or not?

forgot.: it is large screen. when changing the atty it does say "new", "save" up/down. still do not know if that is new or old.

The atty lock firmware is the newest large screen firmware. They could have meant the latest version of the chip when it was made.
Atty lock isn't desirable anyway but check for the celsius bug, if it's fixed then you are good.

 

[nic_fix]

how do I check the Celsius bug? mine seems to be only in Fahrenheit. I imagine there is a way to switch but I don't know.

 

[dr g]

celsius is keep adjusting temperature down and it will switch, then adjust up past max to turn off.
then adjust to a low wattage, say 10w and fire it. it should not preheat and the temperature should not display.

 

[nic_fix]

I got to Celsius, adjusted up to off. set to 10 watts. fired. display immediately showed 2 watts then started showing different wattages. as it usually does. did not show temp or tc. I assume this is the bug? does this affect functionality using Fahrenheit? I am now perhaps furious with hana. they told me the brass ones have the latest chip and will not update it now. soon it shall die as with my other hanas. then I get a new chip but maybe the same one. I really like hana but they keep kicking me. this chip says when atty is removed "change atty" or "save". I do not know if that is newer or older than lock atty. does it look like I should be pushing them for a new chip?

 

[dr g]

hm, that is weird. are you sure those are the messages?

 

[nic_fix]

yes, sure. perhaps it is in fact newer? yours does not do that? maybe hana is right and I owe them an apology. they insisted that chip just came out a couple of weeks ago. that the one I just got has the last revision of the chip made. I have no idea now. one thing though. sometimes it says that when you remove/replace atty sometimes it does not. I gather it is if the ohms were different between the two. maybe that superseded the "atty lock". I searched google for that message and no results. I guess only evolve knows.

however, does it appear to you that I have the Celsius bug?

 

[nic_fix]

don't know what happened to dr. g. anyone else know if I have the latest version. no lock atty. has new atty,save when you remove/replace atty if ohms are different. hana swears it is the newest rev and firmware. I am really unhappy if it is not. this just came out and is $$ so it should have it. they say they have nothing to upgrade.
does my description look like it has the c bug?

When in temp mode (with Ni200 atty) press and hold + and - keys. If you have the latest firmware it will activate the atty lock, otherwise it will activate the power lock (just as if it was in non-temp mode).

I know Vaporshark just cut the new DNA40 firmware into their production on March 20th. I'm guessing Hana didn't have it before then either and I'm thinking all the brass Hanas were made well before that date - they are a limited edition and have been on sale for several weeks now. So it is very unlikely any of them have this latest firmware unless they did a second production run.

My brass Hana was delivered to my house on that same March 20th, so I wasn't expecting it to have atty lock, and it doesn't, but I have not had any problems with it and therefore I'm happy with it.

 

[nic_fix]

thank you. it indeed does not have atty lock. I did not realize it was that new. she probably meant it was the newest chip at the time of manufacture. I imagine it took them a while to make each one of those. then on sale 3 weeks. low serial. oh well. as stated above and by others apparently I am not missing anything. I did not know about the new atty/save but I figure it is not the last revision made. it can't be from a simple date perspective. apparently hana does not even have it as of a few days ago. I called them and they said they have nothing to upgrade it to even if I want to pay for it. normally they will gladly replace free of charge anything that is malfunctioning. mine works fine though. I guess what I described is not the Celsius bug. I use Fahrenheit anyways. well, it is what it is and it is fine. I did not realize that was so new.i am happy to have the brass one regardless.

Can you explaine what the celsius bug is? I have a genuine dna 40, and the celsius option seem fine to me.

Sorry, It`s already explained. I have no atty Lock, but that doesn`t bother me. I have the hcigar dna 40 and I am very happy With it.

It only affects when you shut off temperature control while in Celsius mode. Workaround is to shut it off from Fahrenheit mode.

FWIW, I sent Vaporflask an e-mail last week about the "atty lock" wanting to know if it was on their current flasks. Their response was they "thought" that the Vaporshark rDNA was the only device currently receiving this chip (w/atty lock) from Evolv.

Hope this is some help, Joe

It is currently only in large screen boards.

 

[nic_fix]

looks like I am getting it after all. scrambled screen bah. that makes every dna40 I bought broken. not one yihi. is not going to stop from buying more either. the better mods all happen to use dna40. which they replace free when it bonks.

edited: I was told wait about three weeks and I will be taken care of. they are releasing yet another revision of this chip to further weed out bugs. apparently if coaxed right you can still manage to summon bugs out of the lock atty revision. don't know how many people encountered them yet. good deal. why fix it twice. although I have a feeling the forthcoming revision is not the last. nice at least that evolv stands behind their product and continue to do their best to make it right. honestly I do not see how complicated a little pic chip can be but obviously I am wrong I guess. I am just happy that they try their best not to leave customers in the cold. that honestly stands for a lot today.

update: okay the hana bit it. dead. guess I have to wait three plus weeks now but I bet that is not the end of this disaster. I have multiple dna40 devices and all died at some point. luckily all these manufacturers stood behind them. always buy authentic or toss in the trash.

Thanks for the info in this thread. I guess I also better wait 3 more weeks to buy a big screen DNA40. I have had at least 2 out of 3 of my DNA 40 mods screen bug out.

The "atty lock" feature is a good addition, because sometimes it will happen that because the atomizer is warm the refinement will increase the resistance. And even if it's the connection (I doubt it) it's better that the chip assumes a lower resistance and reduce the power and vapor instead of overheating the coil (dry hit!).

How many revisions / bugs can the put into these chips!!? I was hoping the gold version would be the final bug free version.

Refinement should never increase resistance in proper use. That is pretty much always the sign of a bad connection.
Atty lock is frankly only there to shut people up who don't understand why it is bad.

Also regular screen boards have been glitch-free since last year.

 

[DejayRezme]

So the screen glitch was eliminated in the "gold" version but the big screen version still has the glitch?

And yeah it could be connectivity even though that specific atty and build always had good connectivity before. Only when I chain vape, overheat the atty and let it sit it sometimes shows higher. I'm pretty sure the refinement can screw up when chain vaping. But yeah it could be connectivity of course.

But the point still stands, even if I have bad connectivity it's better for the chip to keep assuming the lower resistance because otherwise the chip could overheat the coil if the connectivity increases resistance up and then back down again. It's better to produce a weak vape instead of a dry hit in case of user error. All in all I'm just no fan of refinement. A warning message "check connectivity" would be ideal.

 

[dr g]

Connectivity does not shift resistance up, it causes a re-read while the coil is not cooled. There is no perfect solution here; without a level of automation to calibration the accuracy of the displayed temperature is compromised.

Problems are problems, IMO I'd rather know than have it covered up, and in the end you learn how to ensure a good build. As a result I haven't had a dry or burnt hit in going on six months now, other than me making real mistakes.
