I opened it and it was a PITA to open BTW, uses the smallest hex/star screws of about 9 mods I've owned and I do own a set of like 30 different mini bit heads but had to file down a flat head to fit, anyway, it seemed all connected together, I didn't remove the board from the mounting and totally disassemble it, I just checked the solder joints all seemed good. I did find a quick and free website to link a video trying to show the problem (which could easily be forged but whatever I'm not into scamming people, I think they need the video to make claim to their supplier), anyway the only reason I went through with the video thing is because their warranty policy DOES say you need to link a video if defective. https://www.efun.top/warranty-policy I guess that's the price of buying from china (I guess it's cheap shipping only from China-> USA and not the other way around for returns). I don't think I've had a problem like this with china stuff usually it's something cheap on ebay I end up with for free or a partial refund. I don't know if fasttech is a similar process for defective, but I'm buying the same MOD from there tomorrow and will somehow get a full refund for this one, maybe I'll get to keep it or something then sell it basically for parts. So yea to summarize , yea it might not be evolv's fault, it could be the assembly, overheated from soldering etc done by the brand Thinkvape. And re: the several DNA mods I've had to warranty due to battery error usually , well hopefully this newer 250C chip is less prone to that, and I still buy DNA because I sort of do trust to USB charge it which makes it unique vs having to open and take batteries out all the time with pretty much every other MOD brand.

I was able to get a reply using their website's Contact Us form. They replied the following which I'm not about to do all this with video and stuff.... I don't even know how to,, I'll mention that once, and see what they say. Or see if efun will pay return shipping for a full refund (if I'm not mistaken it's only cheap for them to mail to US and not the other way around, but I dunno). I could open pp case for ~$8 partial for warranty shipping but who knows about this chip? you buy something defective, you return it for a new one. asking on forums and escribe in developer tab is ridiculous. My first time wanting to return something from china besides cheaper stuff on ebay which goes smoothly as it should. This is like because it's electronic and might be able to be warranty repaired makes it different, but like if you bought a new laptop and it doesn't even turn on, you'd rather get an exchange of course instead of having it warranty looked at. And also with a MOD IMHO it's a safety concern since I buy DNA only because I can USB charge it. I don't think I'm being too picky by not warranty'ing it unless the chip can be guaranteed swapped out. how did this board even go into circulation? evolve doesn't check them for working, or was it something like maybe it was dropped or heat damaged, yes it could also be ThinkVape's fault if not connecting the DNA chip correctly or scratching it or something or overheating with solder.. Now I will open it and check obvious connections but that's all " 1. Send us an picture of the S/N number. You can find it printed on the package used for holding the item. 2. Send us a short video to show the problem clearly. You can also say something to ensure we can find the problem easily. Kindly note that the video should have comparision, and will show us the problem clearly.

I didn't open it, and don't want to, don't want to void warranty or waste my time because I think it is connected. Now I can't email efun.top where I bought it. I linked this thread to them and said it was dead on arrival and explained, I get mail delivery failure using my mail.com. I tried several times and with chrome and IE11. I tried different emails (still mail.com but still this is getting ridiculous..) I left a message though their website contact form, so maybe they'll get that one and I can also reply to it to. I might do a paypal case which I think I'd end up with the mod free. The only contact info I could find is: support@efun.top and jarry@efun.top feel free to test email them efun.top gets good and safe reviews, and I highly doubt they're purposely blocking my email, but regardless I really don't want this sketchy chip even to be 'fixed' by evolve. I USB charge my DNAs and don't need any problems. If I do a paypal case I think I'll end up with this MOD free I can sell for about $50 plus the original $106 and then order same MOD from fasttech for $116 Fasttech is the best in china I guess, never had a problem with them and spent about a grand I guess I either trusted efun.top enough to save $10, or that FT was just out of these at the time. (if anything, now, I think efun.top might be knowingly selling a few mixed in here and there possibly-defective MODs, not running an email-blocking scam, IDK though. I don't even want to pay $6 to mail it to evolve for warranty even if they say they promise to change the board out instead of 'fixing' it.

I'll open and check if all soldered, but if not, then now I have to loos emoney for shipping it to evolve for warranty, and get back a possibly sketchy board. Since I bought from china with paypal (loophole? thought no e cig stuff with paypal) but anyway, buyer always wins on paypal, so maybe Chinese seller I'll just ask for partial of shipping cost for warranty, even though I could probably work the situation to get this POS for free.

I checked before and it was already 3 cell and all 3 show 0.00V. hard reboot didn't fix. I'm suing Samsung pink 30Qs almost new, they work fine in Hcigar VT250s dna200. Only other battery I have is single 18650 for DNA75 MOD. I'm supposed to buy new batteries now to check? See this is what I'm talking about. Or send it back to china and wait 3-5 months of total transit time for a MOD? I don't want this chip even. And not from all this opening closing one of these stupid glued-on battery door magnets fell out (held by tad of glue not evolv's fault but basically). Would have opened once and USB charged thereafter. what a joke

ok it found it in escribe, auto detected and % bar installed it but that didn't fix anything, how do I hard reset it or actually update it or something? btw "Production History Wednesday, April 17, 2019" it's giving the good ole CHeck Battery when I fire, it only turns on if USB connected. I reset to default escribe. I dont' want to crack

I AM still using that version 1.2 sp 5.2. It doesn't update itself I guess. or ask to. ok. I don't see any update tab or anything except APPLY SERVICE PACK, but I'll just remove it in cntrl panel now and reinsall, then if doesn't work I'll try APPLY SERVICE PACK. Ok new version says 2.0 SP 19 we'll see if it work

received DNA250c think vape finder today from china etopfun (researched to be very trustworthy). DOA basically, getting common problem reading about 'deep sleep dna250c' or not turning on, not going to attempt to learn and digest all this BS in these BS threads like this!: https://forum.evolvapor.com/topic/70271-dna-250c-paranormal-clock-error-usb-not-recognized/ https://forum.evolvapor.com/topic/69863-wont-turn-on-from-deep-sleep/?page=6 mine isn't recognised by escribe. Also, never had a mod do this it installed itself via windows 'setting up dna250c' popup like when you install a plug and play new keyboard or printer or something, so I'm supposed to trust what this now-sketchy a** mod installed on my PC. I'm not going to even get into it with this BS trying to fix it with forum questions. I've been vaping since 2012 before it got BIG and evolv is really p'ng me off - really the only thing they have going for them is they can safely usb charge multi cell, otherwise I'd never buy them again. EVERY dna I've owned, maybe 4 differnt mods, gave me a problem, luckily they did warranty twice for me, once past warranty and changed the board in my 200 which has been good so far, but the others give check battery error or something possibly caused from USB charging it (no, they don't explode from USB charging but the charging circuit or something does break eventually I've found). this dna250c is not turning on with known-good cells. Plu ginto usb gives CLOCK ERROR CLOCK ERROR 4% battery, again escribe can't recognise it to update firmware or hard reboot. Tried holding all button configurations, firing 20X etc does not turn on without USB but then can't even use it with %100 charged cells says 4% and only lets you cycle through kanthal/watts/replay etc. Thing is, I'm okay with if this didn't start off on the wrong foot and I would have used it gladly knowing the USB charging might break it in hopefully under 12 months then just warranty it, but now I don't even want anything to do with this F'd chip, I don't want it tinkered with by evolv like they've done with previous mod that also broke again in like 5 months and/or I got it back and it was still givign me problems. I want a NEW CHIP, I don't think I can send this back to china for replacement/refund, evolv will probably tinker with chip then I don't feel safe/comfortable with this sketchy board I want to almost crack the board then send it in like that so I get new quality chip. really getting annoying all this RMA forms and mailing and waiting back to use new mod and then hoping it's as good as it could be

I received my DNA250 mod back from evolve warranty and it's working great so far. It was giving CHECK BATTERY and not firing no matter what I tried. I asked them if they can tell me how it was fixed so I can post it here in case others have same issue. I said I don't think the board was replaced. They said there's no notes from the tech and said they think the board was replaced and to check the puff count. So are the red stars the total puff count? 681 seems a lot for I only ran about 10mls of juice with it since I got it back, but I just noticed I tap fire a lot even for just one hit since I don't have a power ramp or TC I tend to tap it up to temperature and may tap fire like 5 times for just one actual puff. I originally said I doubt the board was replaced , I didn't tell them because I can see the screen is still a bit dirty/blemished on the edges but maybe they kept the old screen and just replace the board? ALSO when I hit GET INFORMATION in escribe it takes me to a URL that says this: I bought the MOD January 2018. But that's still a year after the date this shows it was programmed, so that's a long time and would be an extra 1.5 year to today if it's actually a new board installed, so IOW maybe they're both from a big batch made Jan 9 2017 (if there's indeed a new board installed)? ___________________________________________ Production History Tuesday, July 2, 2019, 3:18 PM @ Hudson, Ohio, United States Mod tested A+ Battery tested (3.65V min. cell, 0.9A min. charge): 3.8V cell 1, 3.8V cell 2, 5.166V USB Firing tested (100W for 5 seconds): 97.56W Monday, January 9, 2017, 4:34 PM Board programmed

thanks craig, if you say so, I guess so . At least it didn't blow up or anything. I'll mail it back to evolve so they can take a look. I might slip my DNA75 in there too which sometimes gives me TOO HOT error for no reason and won't fire. I'm probably NOT going to buy another DNA250 board to replace this one if it comes down to it. As much as I loved this mod which is able to do dual or triple 18650 mode and is TINY for a dual 18650 mod. I think USB charging is killing the IC circuit as you said. I don't know if they'll replace the board this time (they apparently should have the first time I warranty'd it and it bricked again a couple months later). I'll link this. I just hope they care enough to try and prevent this from happening with future boards - that's why I'm going to buy a DNA250C next and hopefully the IC will never fry or anything bad happen.

YES! with two Samsung pink 30Q 3000mAh 3.7Vs, it boucnes around a bit but stays at: Pack: 7.56, cell1: 2.34V Cell2: 5.22 Dual 18650 mode: I press fire get CHECK BATTERY and battery bar is empty but %100 charged on an external, barely used these cells, I press fire it says CHECK BATTERY if connected to escribe, but if i disconnect from escribe and press fire it say EVOLV DNA250 for as long as I press fire. 3 cell mode = pack = 11.78V , cell 1 = 2.34, Cell2 = 5.22, Cell3 = 4.22V I got these cells right here: https://www.ebay.com/itm/SAMSUNG-30Q-Rechargeable-Battery-High-Drain-Flat-Top-3-7V-18650-VAPE-LOT-MENU/172954891880?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 evolv DID grant me a rewarranty for this but maybe it's the cells? The other two batteries I was trying were 2 sony greens that when I put them on an external Xtar charger one says NULL and won't charge. The other seems fine. I think I tested with these Sonys before but I did also just test with the sansung 30Q pinks and got CHECK BATTERY. BTW, the Sonys have some strange markings/burnings or something shown here but people are saying there that it shouldn't be a problem but I won't be using these cells again and will recycle them now that I see it saying NULL on the Xtar: https://www.e-cigarette-forum.com/threads/what-happened-to-these-batteries.911913/

^ and I agree, the dna DOES charge very balanced and as good if not maybe better than a dedicated nitorecores or xtars but it seem that mine are always frying after about a year of USB charing. I'm guessing even a lot of DNA users are using external chargers and so this problem isn't as obvious?

^ Translates to In one year of operation, Triade 250c with Samsung Q30 batteries (charging via USB only), there was not a single problem, the voltage on the batteries was +/- 0.003 V. Once there was a problem with the board overheating when Vaping was charging, after which I did an analysis corps in escribe and this is not repeated. Balancing batteries when charging via USB is ideal and even expensive third-party chargers produce more mediocre results.

I tried everything man, I tried multiple outlets, I charged the batteries in a Xtar quality charger, it just give CHECK BATTERY in 2 cell mode or 3 cell mode it just shows nothing on the screen basically just flashes 'DNA250' or something like that

I have a 30mm velocity style RDA that I'm hoping to make really big clouds/builds with just for fun now and then - not an everyday vape of course (I normally vape only single coil 5 wrap fused Clapton RTA at about 18W). My triple 18650 HCigar VT250s DNA250 is bricked..., so I'm looking to buy something new. Hoping to find something similar to the VT250s which can hold dual 18650 (167w?) or triple 18650 (250W), but with a newer and probably Color DNA board, but if no such MOD exists then I'll get a triple-only 18650 DNA (triade etc). Anyway, so is this even possible considering the DNA board can only fire down to about .10 ohms? I don't want to go the unregulated route and risk anything and as mentioned this huge build will just be for fun now and then so don't feel like getting a $200 unregulated 4-cell MOD just for that. What would be the best and safest batteries to try this, and should I make the builds Stainless Steel? I have SS fused Clapton wire. Was hoping to basically make long quad coils with that in the 30mm RDA but not sure. Either way even if I can only get like a triple coil to fire with the DNA instead of a quad fused Clapton 30mm it should be a ton of vapor.
