As soon as you have downloadable code that needs to be applied to a firmware code you can hack it.

And reverse it as well, meaning you already have a pipeline so you can pull whatever you want out of it.
No, not if the download is securely encrypted and the only place it gets decrypted is by the bootloader inside the MCU.

I will only mention the issues you speak of to say this... how many occur on the latest versions with the latest firmware? One can't trivialize the updates either....compare the dated issues you speak of with the latest firmware version and tell me that nothing has been done...

This is probably the most civil XXX vs. YYY thread I've seen on ECF (and only a few survive without being closed).....to say anybody has ruined it is just one opinion that I don't share...we should continue the conversation with the latest facts to compare and not dated information IMO. The V4 I just received last Wednesday has not shown any of the dated problems you want to tell others still exist.

We have not had the discussion yet about all the bugs that folks are mentioning with the J board (SX Mini M class). Hopefully they will be discussed in fairness for comparison purposes.
I have both boards in devices and like them both, I also got lucky with my launch rDNA that had no issues.

The only problem with the updates with Evolv, while I do recognize they have made positive changes to fix things, this does nothing to help early adopters or people who purchased their device even up to one day before a new update, they are just out of luck. That's the only thing I found unfortunate.

Kudos to Evolv for fixing everything, it would just be nice if those changes and bug fixes could be passed along to the actual end users with devices already in hand :)

On a side note, I have a Dicodes 2380 on the way, so hopefully we can add a second "vs" here soon ;)

dems86..... many, many,many early adopters RMA'd their boards. Evolv added a new feature "atty lock" later, after public demand by those who did not like/understand the refinement process and since it was a new feature it did not qualify for the RMA process. I understand what you are saying and hope this helps.... The Dicodes looks interesting....will look forward to a thread where we can chat about it....

That's really difficult to say since to my knowledge we have no objective information available on the different versions. Or for that matter the ability to tell what version one may have received other than "Latest Version" being stated by vendors.
That being said it would be extremely difficult to do objective comparisons when one of the devices being compared "DNA 40" is a moving target. If not locking in what point you have collected that objective data for comparison it's a waste of time to even try as the results will be differing at each revision.

to say anybody has ruined it is just one opinion that I don't share...we should continue the conversation with the latest facts to compare and not dated information IMO

The fact this conversation is even taking place which is not "DNA 40 VS SX350j" oriented or providing any comparison at all is indicative of numerous posts in this thread which has ruined the thread IMO.

We have not had the discussion yet about all the bugs that folks are mentioning with the J board (SX Mini M class). Hopefully they will be discussed in fairness for comparison purposes.

You certainly should, I believe that was the intention of this thread to reveal the pro's & cons of the two devices. Not to whitewash, trivialize or mislead the reader just because brand xxx is the one someone chose.

I'm confused? Didn't you guys say it was only like 5% of boards had issues?

Need to look up those posts but I'm pretty sure that's what you guys said. Is 'many, many, many' 5%?

I have not paid too close attention to the SX bugs being talked about. I know from Yihi News they are putting out an update in May to "modify a bug". Maybe you could let us know the bugs being talked about, and specifically what bug is being modified, so we can discuss them. My point being that bugs of either should be compared and discussed objectively.

this 'refinement' process... is it good or bad?
I understand that the resistance of nickel does change over time, could be due to gunk or heat.. the SX 'locks in' the resistance for the atty, and stays at the setting until user decides to reset again. I've read about users using the same coil for days and tanks after tanks, without mentioning resetting the resistance.. so if the coils do change in resistance, without auto refinement, the said user is basically vaping on inaccurate setting?

From my personal experience ( I use only manufactured nickel coils) they refine no more that 0.01 or 0.02 ohms. After they refine I adjust the temperature. I could set the "atty lock" at that point but really, for me, see no need. I use that setup for days to weeks and refill many times and do not need to adjust further. This is consistent in my experience of using numerous manufactured coils of different brands (Aspire Nautilus, Aspire Atlantis, and Kanger ST nano).

I guess refinement being good or bad depends on the person. To me refinement is a good thing as it monitors the coil. Others will disagree. Probably just depends on what works for you.

I personally like it BUT I still have to test it in 43C heat we sometimes get here in the summer. For now, my atties have been rock solid after initial refinement.

Heck, I'm about to order a second chip, something that I thought unthinkable just two months ago.

In a stable system, refinement seems to be a desirable option. Does refining a build by 5-thousandths to 2 hundredths of an Ω noticeably effect vape quality though?

Refinement seems like it could be a nightmare when the technology is poorly implemented in a mod or when dealing with an electrically unstable build or atomizer. Do the tech manufacturers, mod manufacturers or vendors have a list of stable atomizers suitable for use with TP? Do any of the creators/resellers have recommendations for wire by brand, gauge or temper? Do any of those making or selling TP products have published build guides?

Many questions you have asked that I rightly have no answers for. Quality of the mod build is important as is coil/atty integrity and connectivity. From my experience I can tell a difference in 0.01 or 0.02 ohm refinement in vape quality (flavor) which only requires adjusting the temperature a bit. Others may not notice a difference and I think the atty lock feature is something they would use. Just my thoughts...

I guess you now understand what playing in F mode on my dna meant to me... Mod in my left hand, C/F converter app in my right hand and adjusting temperature with my nose lol :D

Many questions you have asked that I rightly have no answers for.

This is my point exactly. I don't have all the answers either. But those who should are not communicating with us. Why? Fear of stolen IP? Fear of possible litigation? Not having the answers themselves?

TP technology is released to the masses and we're told, "Have fun. Oh yeah, use nickel (Ni200) wire." Once again we're left to figure it out for ourselves. With little to no instruction and a multitude of variables in the process, it is no wonder we've had wildly different experiences. Production and software glitches have been frustrating to some but understandable in a new industry. However, the simple fact of requiring those who want to utilize TP to practically become electronic techs is unacceptable. You don't set the goal of making the process easy or dummy-proof and then fail to communicate the required information to make it so. Please don't misunderstand me. NONE of the manufacturers are communicating well. They're still too busy getting their acts together and, yet again, leaving us to figure it out for ourselves.

None of this is rocket science. But if we expect this particular technology, for our purpose, to be perfect or 100% accurate, we're fooling ourselves. Staying within the ballpark is probably the best we can expect. The competing technologies seem capable of doing that. Now we must figure out how to get ourselves and each other into said ballpark so we can play too. Just my :2c:

"functional erors and inconsistencies not attributed to anything but the device itself.".

Regardless of the build the following errors to name a few were present and recorded on the DNA 40. If you somehow can explain these away with the coil build please do so.

Not detecting the correct resistance of an Atty even after removing it, firing it on a correctly functioning device then placing it back on a DNA 40 which still detected incorrect resistance
Irregular battery bar
Sticking in power or temp mode
Scrambled screens

Your certainly entitled to ignore whoever you wish. That does not diminish the failures detected and reported on with the DNA 40

The screen display and battery bar has absolutely nothing to do with temperature protection. Odd resistance readings and incorrectly being in power/temperature protection mode are issues commonly associated with wonky 510s and/or poor coil and/or mod builds.

Trusting someone who used that build in temperature protection mode to accurately troubleshoot and assess the source of their woes seems beyond foolish to me. That said, finger pointing from a place of ignorance is something I routinely ignore although there seems to be no dearth of people who consider this type of behavior to be highly enjoyable entertainment.

Evolv in my eye still has wonky boards in the newest version. I got the latest version on a Hana V4 and after 1 day guess what? It glitched. I have had the Vaporflask, Vaporshark, Hana V4, IPV4, SX Mini. To be honest both boards are faulty and each have their quirks. Arguing between the 2 is useless as to who is better because neither one is 100% perfect. For right now neither is worth the money to me and the aggravation of sending mods back in as much as I have had too or other people have.

Here is a response I found about new Evolv boards:
"Sorry to hear you are experiencing an issue with your MOD. The board has been updated by Evolv to ensure it does not get stuck in scramble screen mode. The screen may scramble but will reset itself after a few seconds"

Does that sound like Evolv worked out a good fix?

I have read that there was a "Reset" added to essentially to hide the scramble problem, while not actually fixing the problem it's supposedly masked it so the user would not have to deal with the inability of being able to read the screen. No idea if this is true or not just what I've read elsewhere.
