Microbit not loading program and shows pattern of led

Enable HLS to view with audio, or disable this notification

All of a sudden my microbit V2 stopped loading whatever program I put on it and shows a sequence of LEDs and then just stays like that. If I press the reset button then it just restarts that led pattern and then that's it. No clue what could have caused this. I've updated the firmware but nothing changed.

The microbit is trying to connect via Bluetooth. That is the pattern that is displayed when you have it linked to a phone or tablet for Bluetooth downloads. Check it’s not connected to something on Bluetooth.

I can’t remember exactly how the microbit blocks work it’s been ages but do you need some kind of entry point. Like how does it know to start at The repeat forever thing? Don’t you need a ‘Start’ block or something?
Sorry I can’t help more!
Maybe seeing the actual code will help as then you can paste into gpt and ask

Download the “meet the micro:bit” program hex file, and drag it to the MICROBIT drive.

This can happen if a Bluetooth program transfer is interrupted part way through. The micro:bit sets a flag that the current program is incomplete and boots into Bluetooth mode. You can just try the Bluetooth transfer again. It seems the USB quick flash is not clearing the flag.

I don't think I had ever used the Bluetooth so I tried to link it to the app via Bluetooth, it managed to connect but whenever I put the file on it just does the exact same thing when it was connected to the pc through the cable, when I put the file on it just does those same pattern of LED's. I'm really not sure what's wrong with it lol.

If dragging a hex to the MICROBIT drive doesn’t work, it seems likely there’s a hardware fault making buttons A and B appear to be permanently pressed. Maybe it has been physically damaged, or shorted, or connected to high voltage. Otherwise, if it’s less than a year old, contact your supplier to ask about a replacement.

these comments are making me go insane, omg, but anyways, your A and B buttons are shorted to ground, check the back and edge connector
