DNA 200 suddenly locks itself when firing

[Brandohim]

I have a boxer dna200 and rarely used it. Now, the mod locks when firing. It locks by itself. Was working fine then, it starts to lock when firing. Could y'all help?? Please and thank you.

Locking as in 5 click locking? EScribe's Device Monitor will show you if your fire button is intermittent.

Sos to state the obviouse but often the obviouse gets over looked, Have you tried updating it through escribe and restoring defaults, ie 5 clicks dropdown box may have been messed with.. also charge the battery.

[Brandohim]

Factory default performed. It's at 5x clicks. Everything seems normal it just locks itself whenever it wants to. This forum rocks... I know we can figure this out.

[Brandohim]

I Have a video of the device monitor and a csv file.

Your not the only one this has happened to. The only real fix is to RMA the chip. One work around that has help some people is to increase the number of clicks to lock the device.
My Vaporshark does the same thing. It will lock mid puff and the 5 clicks do not show up in device monitor. I feel this could be fixed by firmware, by telling it that there must be X amount of milliseconds between clicks.

Same problem with a vaporshark. It seems that it's working better after applying some contact cleaner to to fire button. It's very annoying though.

If it was happening to me id fit my own fireing button, one of thoes little silver tactile ones and seperatly wire it to the solder tabs, think its tab 1&2 on the drawing. Could even tear the old one out and then set it in place with some araldite.

unfortunately this is happening to my recently repaired Vaporshark dna 200. i had it set to 3 clicks but out of necessity i had to change it back to 5x. still auto locks now and then. i'm debating whether or not to send it back for a second time.......

my guess is, when i sent my mod into vaporshark for a new board, they replaced my bad board with a new board that had a fire button that was made on a monday or friday. my luck.

send me a couple lace. i'll try and solder one to the board and see if it's better than the one that's in my VS 200.

Unfortunatly they got used up very fast. Lol.. seriously though for a few seconds. 1.2.3.. there thats better... No realy, ive seen a few of thoes with a wiered up button conversion, theyve looked bit of a bodge job, but still a repair, what i would do, like i said earlier i would strip the old one out, and get one of the little domed tactile buttons, tape it in place of, and pack it from behind, centred up and then just infill around with some araldite, then just tidy it up with a dab of black or silver paint, (no drilling or fileing involved)

vaporshark and same thing here, it randomly locks itself while vaping, 5x unlocks but wonder how it locks itself in the first place.  I am not chain vaping that quick  .

I have no VS but have been giving this some thought the last couple of days. Keep in mind this is just something i'm pondering, here goes.
Now I'm not talking about mashing down the fire button excessively hard but could this problem stem from pushing it too lightly?
Maybe someone that's having this problem can give it a try and report back.

Pretty much would cause the above, how about.. distroted inner switch componants, that are not much moor than tiny slithers of silver paper..either through wear or impact..

my 'auto locking' issue has seemed to clear up, i hope. i just now set my VS 200 back to 3x click to lock and unlock. we'll see if it behaves. i pretty much did what dwcraig1 mentioned in his post. i gave the fire button about 20-30 hard pushes. not crazy hard, but pretty forceful. my thinking is by pressing the button harder a bunch of times it might force the contacts to make better connection, by reshaping the wafer thin metal dome contacts inside the switch or clearing any debris. since my device still is under warranty, i was not too concerned if the fire button broke or got worse. if the button starts acting up again, i'll just send it back for a second time. i'm not saying do what i did. i'm not even sure it's remedied. will report back

I have experienced this on the 3d printed case I first used. It was a clearance issue causing the fire button to constantly be pushed in. So just chain vaping and taking two drags in a row caused the board to go into "locked" mode sometimes even happening mid-hit. I fixed it by lightly sanding the back of the buttons. This should not be the cause in a manufactured box but I thought I should share my experience anyways. Can you try loosening the board mount screws slightly? Just as a check to see if this is a clearance issue.

When push "FIRE" button DNA board "auto-LOCK" or "don't work" - let's cleaning "FIRE" button. Seeing what can be seen through the magnifying glass.

I'm also having this issue after not using my mod for a month.  It was doing this occasionally before and I thought maybe I was accidentally hitting the button and didn't notice but now when I do manage to unlock it it locks itself again next time I press the button.

is this a Vaporshark dna 200 or a regular dna 200 board? if it's a VS they're completely different buttons soldered to the board compared to the regular 200 boards and are harder to clean out. if it's not a VS board, the button actually comes apart so you could clean it out with some alcohol or an electronics grade/safe cleaning solvent. depending on how bad your situation is you could just set the number of clicks to lock the device higher ("7x or 10x to unlock" basically makes it harder for the device to auto lock itself) if you're uncomfortable taking the button apart. or open a ticket with elvov from their website.

[wantron]

It's direct from Evolv and I printed my own case. I'll take it apart and try cleaning the button. Thanks for the protip.

I had the same problem. Turned out to be a flaky fire button. VaporShark repaired my mod, replacing both the fire button as well as the board. Worked like a charm after I got it back (no more locking problems). Only now the screen has died. Mod still fires, I just can't see or change any settings, so it's on its way back to VS for another repair (still under warranty). Glad to have my Sigelei 213 on hand.
