Nice work. I'm glad the teardown went smoothly for you. I'm in the middle of attempting to strip down my RX 200 (black) to switch the board out for the DNA 200. I originally purchased the Lavabox, but had to send the board in due to the board getting stuck when pressing the firing button. I recently purchased the RX200 with the intention on switching out boards. I do like Joyetech's board, but only in wattage mode. I hate the 3 clicks to scroll through the temp settings. I much prefer the DNA 200 for customizing curves. Anyway, upon inspecting. I found that the 4 screws (middle to bottom) allowed me to pop the screen cover off. That's where work has halted. Wismec have glued the board in place ever so slightly. This doesn't appear to be the case for you on your DNA 200 version. I removed 1 gold or brass plated screw from the bottom right of the board. Is there anymore screws holding down the board that you can think of? I also have a duh moment going on. I don't understand how the board is fitted under the firing button, as the enclosure covers the firing button up. I have noticed that Wismec have soldered long positive and negative wires coming from the 510 to reach the pads located at the bottom of there board. I can see a minor alteration being made there. I may need to shorten those wires as the DNA 200's contacts are located at the top of the board for the 510. I'm assuming the 2 screws located at the top of the battery sled and the top and bottom of the mod are holding the sled in place. Is this correct? For anyone looking into doing the switch. Please do NOT follow my steps as I could be completely off the mark. I've not done any prior research before attempting any of the above. The mod cost me a little over £30. I would not recommend doing this if the RX is your only mod. Edit, I thought the positive and negative wires looked a little thin. Thanks for providing those images ChunkyButt200. Now to figure a way around removing the solder from those 510 pads. Those wires are way to short to pull the board down a touch to gain access to those pads. I can see this being a pain the backside to complete. Not to mention, the firing and wattage buttons need sanding down from what I've seen on reddit. [/QUOTE] If it is anything like the dna 200 version There is an extra screw underneath the sled that is exposed when it is moved out of the way.
