The core is looping flashing white then solid blue over and over

Still the same…

i uploaded some videos to my instagram

Was the core flashing white when you performed a factory reset?

Try performing a factory reset again and see what happens

BTW, I took this video right after this

OMG, i am such a fool. :frowning:

I just notice that the LED is flashing blue like “listening mode”, so i tried to access my spark and key in my Wifi SSID and Password.

And then my spark revived!!!
