I was using it when it went off.

If you said so , try charging or change battery to see, does it make connecting/disconnecting sound when plug to System.

Can not boot to download mode

you’ll need to use jtag to boot to download mode then flash firmware.
Try @aniugchukwu’s suggestion.

Maybe the battery is drained.
Keep charging or have the battery disconnected and reconnected
