I am on a Mac (running Mojave). I was trying to deploy my makecode game using Chrome. Initially it worked fine, the Meowbit was detected but after I hit download, the Meowbit screen changed to sad face and 090. I have tried disconnecting and reconnecting to all ports on my laptop, turned power off and on while connected and disconnected to the laptop and it still shows the 090 screen and the top right LED is flashing red. I have hit the reset key, when I do that, the screen goes black for 1 second and goes back to the 090 error code. I also tried holding down the left arrow and Reset key, that displays a File screen for one second and then goes away and returns to the 090 screen. Currently my mac is unable to detect the device at all.
Is there any hardware key combo that I can use to reset the device? I will try again tomorrow by connecting it to my Windows device to see if the device is being detected.
Any tips, even if I can flash the system is welcome.
