My mBot ranger has decided to kick the bucket. The motherboard gives me two blinks every half a second, it will not accept any code, and it will not connect properly to mobile devices. And yes, already tried charging the battery (I have the rechargeable), updated it in 5.4.0 and 5.4.3, and tried uploading code. Also resorted to ChatGPT and it recommended this “bootloader flashing tool,” which I don’t have access to (go-figure, stupid ai! NO CONSUMER has access), and it recommended I check the github, which had nothing. Anybody have any ideas?
mBot Ranger blinking and not accepting code uploads

Hi @Rosco, the best thing to do is probably contact support here, which might take a while:
support@makeblock.com
Also try with non-rechargeable batteries and make sure the batteries are fully charged since dead ones will cause similar behavior.
Try unplugging all the motors and sensors, plugging in the main board to your device, and updating the firmware (remove the batteries while connected via USB, you wouldn’t usually do this but for testing purposes try it.)

Alright, I’ve already tried it with non rechargeables, the robot does the same thing, but unplugging the batteries while the USB power is supplied makes it stop blinking, but it will just stand there in its own personal abyss not doing anything when I send code to it.

Also, the accessories are unplugged, and it still won’t work. ChatGPT recommended this bootloader flash thing, which isn’t publicly available.

It might be the app, uploading corrupt firmware to the robot every time I update it. I have a feeling I should try the web version. Already tried Arduino IDE, and that didn’t work. This is my last hope before I scream at Make block for making a faulty product.

@Rosco Send them the link to this forum post and explain what you’ve already tried so they know; otherwise they’re going to naturally start back at the beginning.
