Help with Camera wifi on MJX X400

Hey, I bought an MJX X400 V2 a few weeks ago. The first day the camera stopped working, no wifi. So I bought a new C4010 camera for it and this camera at least lights up like its getting power, but still no wifi, no FPV, nothing. The instructions are horrible, and there's no tech support from MJX. Any ideas how to get this thing to transmit wifi? The quad came with a C4006 camera, but this is supposedly compatible and I've seen youtube video of people installing it on their older X400's.

Why are there 3 wires on the power lead? I'm assuming power, ground, but then what's the 3rd one? The instruction manual says one button on the controller turns the camera on/off, but nothing happens with that button. Maybe I need to cut the third wire, or possibly jump power to it? Getting pissed off, not ready to wait another MONTH for a replacement from China, and not good enough to buy a better quad yet either.................stuck in limbo here

Did you figure this out?

I also purchased a C4010, for my X400, with the idea of being able to take video (I've got a Windows phone, no way to really use the live streaming, and don't see myself trying to juggle a tablet outside, or purchase a cheap phone just for a quad, at least not yet), particularly I wanted to be able to film my roof and area after windstorms and such.
I'm definitely a beginner with the quads, but that said, I'm decent with most things electrical and was a software engineer for a good many years.
While I struggle to learn how to fly it around, without running into my house (I did manage a lap around the roof today), I'm hoping to figure out what's up with the darn C4010, and why it won't film?
Hopefully someone else who's knowledgeable (I also saw similar videos) will chime in, and help us.
I see the light as well, at least when plugged into the 4005 port, but the camera button on the remote does nothing, and so far I've not been able to get it to record anything on the included SD, very frustrating, totally agree on the manual, good luck there...

TIA, to yourself or anyone willing to help out,

The 3rd wire is a signal wire and in your case it is being used to control the camera on/off I wouldn' t disconect it, don't believe it would be causing your problem. Try switching the SD card in the camera for a differrent one.

This was my guess as well (without getting out a multi-meter, which seemed a little futile, although I guess it would tell me there was no signal, possibly).

I'll tried another card, a 1GB Sandisk that I formatted (FAT) right before trying it. Also tried FAT32.
Nothing, nada, same blank card after toggling the button several times on the controller (the one that supposedly controls the camera). The camera light still blinks as before, regardless of button presses, etc.

I'm open to new ideas (starting to wonder a little though, if it might be our cameras, these tend to get decent reviews, they must work)?

Okay, tried some more stuff, got out my Android tablet, which can see the 4010 WiFi, but doesn't actually display anything from the camera, but it seems to think it is.
It connects, and then I can enter the "Monitor" mode on the app, but nothing shows up, and if I try to capture either pics or videos, it just creates zero-length files, for each (on my tablet, still nothing on the card itself).
Kind of a bummer first copter experience, although I'm enjoying learning to fly the X400, I wish I could video, this was my primary intention, being able to inspect our roof and similar after a storm.

I hadn't tried the tablet previously, mostly because it's not very practical to hang onto a 10" tablet (my only Android device, I have a Windows phone) and attempt to fly, it was enough of a handful just trying to keep from crashing into stuff.

I'm still open to new ideas. Wishing I hadn't bought the C4010 via eBay now, a return is going to be difficult, particularly because I can't really prove it's not working (it does produce a WiFi signal after all), it could potentially be my X400, I guess...
