My nibble was working really well after soldering and I could successfully play some of the saved games on it. I connected the nibble to my laptop, but when it scanned the device for MicroPython, it said that it wasn’t installed and asked me if I wanted to install it. I pressed yes and it started installing. But after some time, it failed to install it on the device and tried multiple times but got the same result. Since then, my nibble has been unresponsive. I pressed the reset button but it stayed the same. When I turned it on, I could see the blue light under the display, but the screen was still black. I took the batteries out and put them back in and changed the fuse but nothing worked. Please tell me what to do.
