Introduction: Factory Resetting a Locked Flashforge Dreamer WiFi Card
From my blog, Booglejr.com:
Not that long ago I locked myself out of the Flashforge Dreamer's WiFi admin console. I asked tech support at Flashforge about it, and they said I had to replace the internal WiFi card which they offered to sell to me. I declined the offer and decided that I would fix the problem myself. Thankfully, the internet always has your back. After some scouring I got a basic idea of what to do to fix this issue. Then, I wrote this post as a guide showing you exactly how to solve this problem yourself.
Please Note: This is a self-tested guide that worked well. That being said I am not responsible for any damages or injury that you may incur either to the device or yourself. Try it at your own risk.
Tools You Will Need:
Alan Key (Look in your Flashforge maintenance kit.)
Small piece of flexible metal (A stripped down twisty tie works well.)
Step 1: Removing the Bottom Panel:
The first thing you want to do is place the Dreamer on it's back. A bed will work well for this just make sure there is a power outlet near it. There are six hex screws in the black plate that will need to be removed. There is an alan key included in your maintenance package shipped with the Dreamer. After that, just pop the black panel off.
Step 2: Locating Your WiFi Card:
At this point you will need plug power in to your Dreamer. After that turn it on and use the touch display to turn on the WiFi. If you can see in the picture above there is a small chip at the bottom of the blue core board. That's your WiFi card.
Step 3: Connecting the Pins:
You will need to take a small wire and connect the two highlighted terminals for about 5-6 seconds. At this point the LED on the right side of the chip will start to flash. Continue counting to around 5-6 seconds. When you are done counting, pull the wire away from the card. If the flashing doesn't stop immediately, tap the connection real quick once more. At this point all you have to do is restart the printer, turn WiFi on in the settings, connect to the network with your computer/tablet/phone, and trying logging in to see if it works. If it doesn't work, just repeat the steps. I had to do it a few times to get it to work.
Step 4: The End Result:
Because this a factory reset all WiFi related changes have to be redone. I hope this guide was helpful and if you have any questions please feel free to leave your comments below.
