got a clownstick from a generous member here. not sure if they want to be mentioned. i have the dna 40 ready go. i'm replacing board because OEM board fires, but no display. i will update THIS post with pics and some tips and tricks etc. of my process for a simple transplant. gotta go to a no heat furnace call first, then i'll start dismantling when i get home.
make sure you got decent work room
take yer time
take a break halfway, if needed. watch some tv go outside, whatever.
when you have all the switch, 510 connector, and batt wires soldered throw some power to the board and make sure all the work as intended.
install board, making sure wires aren't getting snagged or pulled, this is where the patience part comes in. don't force the board in. get a little flashlight and look inside to make sure you're not hitting anything.
once the board's in connect positive 510 wire (screw on), put screws back in for batt + and batt - throw a batt in and make sure it powers up.
remember to peel off the screen protector, the red plast tab, not the black one!
hold screen in place with tip of finger, turn on, make sure it's aligned. the screen on the dna 40 has a shorter ribbon than the OEM board so this is kinda tricky. then a couple small beads of the ole hot glue will hold it in place just fine.
throw the three screen plate screws in finger tight at first, make sure it doesn't take tightening the screws to suck the screen plate down flush. if it does not sit flush w/o the screws that means means something's in the way (board, hot glue, wires) and you could crack your screen torquing down those screws. remember patience, you'll get her. i added a ground from the board to the 510 (this is not a must). here's the pics. I think they're in order?

the lines in the screen are because of my cell phone camera and not the actual screen.
THE BOARDS FROM SWEET-VAPES.COM DO NOT HAVE ATTY LOCK. I WAS TOLD IN AN EMAIL FROM THEM THE BOARD THEY'RE SELLING FOR $35 HAS THIS FEATURE, BUT UPON TRYING TO LOCK MY RES, I FOUND OUT IT DOES NOT.
