So my spark has been deployed for a few months now, monitoring the coffee in our office. šŸ˜ƒ Out of the blue the Spark just started flashing green the past day or two. The wifi is still working, the password hasnā€™t changed. But the spark canā€™t connect. I took the spark off the breadboard and tried all the suggestions in [this thread](http://community.spark.io/t/solved-my-spark-goes-to-flashing-green-forever/7300), and still no luck. To be more specific I tried: 1. Factory reset, re-enter wifi credentials 2. Factory reset, DFU mode -\> cc3000 firmware update -\> spark\_tinker.bin upload -\> re-enter wifi credentials Still no luck. Flashing green. Can someone help me troubleshoot this? Thanks ---

@osman, Which CC3000 patch did you use? Try this: [https://github.com/spark/spark-cli/blob/master/js/binaries/cc3000-patch-programmer.bin?raw=true](https://github.com/spark/spark-cli/blob/master/js/binaries/cc3000-patch-programmer.bin?raw=true) ---

@kennethlimcp I used the one in the cc3000 repository [here](https://github.com/spark/cc3000-patch-programmer.git). I will try the one you linked, as it appears to be different. ---

Updated that firmware, then followed up with Tinker. No diceā€¦still flashing green after entering wifi creds. ---

@osman, are you using CLI? If so, you can get the latest CC3000 patch by doing: spark flash --usb cc3000 You may also want to update the bootloader though it is only required for the new wake-on-pin modes of Spark.sleep(). ---

Yeah, that didnā€™t help either. Using spark-cli 0.4.94 ---

@osman, has anything changed outside the Core like your wifi router/AP or channel or a new router/AP? Have you tried bringing the Core closer to your AP? I had that problem with an original core so I reflashed the cc3000 then tinker and reset the wifi credentials via the Android app. ---

AFAIK nothing has changed, but here at the office the IT department could have changed something. I will say that it is very unlikely the router changed, and I know the wifi creds didnā€™t change. Maybe Iā€™ll take it home and try to connect it there. ---

Nope, no luck at home either. Tried both WPA and WPA2. I think the wifi is fried or something. ---

Trying to connect to my phoneā€™s hotspot is failing as well. I am going to e-mail support. Thanks for all your help folks. šŸŗ ---

Iā€™m having a similar issue. Just got mine so Iā€™m not entirely sure how itā€™s supposed to work, but I havenā€™t been able to set up via smart connect at all, and I can get it to connect to wifi via usb, but trying to put on the cc3000 firmware sets it in a constant flashing green mode that I need to reset to fix. If you find out the source, please post. ---

I ended up emailing support and got a replacement.
