Hub is locking up after flashing with Pybricks

[raj-andy1]

Hello - my Hub is locking up after being flashed with the Pybricks firmware. It was working fine last week after we flashed it and now all 9 LEDs are lit up. I can restore it back to the Lego firmware and it works fine with Spike.
I tried this with another hub and the same issue all LEDs are lit and the hub is not responsive via Bluetooth or the cable. See image of the hub after the firmware is flashed

Pls help

That is how it should normally look when you first turn on the hub with Pybricks. Is it possible that you pressed the Bluetooth button to turn off Bluetooth at some point? If the Bluetooth light is not flashing, you can press the Bluetooth button again to turn it back on.

i think i took the picture when the bluetooth was flashing, what happens after this is that I can pair to pybricks but no code runs, hitting the play button quickly transitions to download and then nothing happens. the robot is just standing in its place

Is there any error message printed in the terminal on Pybricks Code when you run the program? It could be that there is an error in the program that causes it to crash right away.

What happens if you run a simple program like this?

from pybricks import version

print(version)

thanks for the guidance, using this I was able to decode the error message and fix the cabling
