When I called VaporShark they told me to restore to factory settings so it's been plugged into the computer...it's at 99% right now. I'm probably just going to send it back for a replacement. It's just annoying. I have checked the 510, in every way possible way so in guessing it's an internal problem. I'm pretty good with wiring but like you said I don't want to void the warranty and I don't trust my skills enough to start breaking it open.
Here's another weird thing, I'll have no atomizer on and i press the fire button and it says shorted, then I clean the 510 with a paper towel and it will say check atomizer. Then I put an atty on and it will say short again. Just weird.
So I just got a VaporShark dna200 3 days ago in the mail. Got it right from the VaporShark site. For 3 days it was working perfect...then it started saying my atomizers were shorted, it would work on and off but as of today it's totally not working. Even when I have no atomizer on it, instead of saying check atomizer it says short. On Monday I'm sending it back to VaporShark for a replacement but if anyone here has a fix for me I wouldn love to not have to wait however long to get my new one so any advice would help. Or am I just out of luck?
