Yes; I would say it's pretty easy to cause this to happen. No, you haven't bricked anything. Something in your boot is crashing, probably U-boot. Your eMMC is working, else the power lamp (which is controlled solely by software) would not light. If you can afford to wipe the eMMC and rewrite it from scratch, then simply do that. You'll have to disable it; boot from SD; and early in the boot process, re-enable the eMMC. I know there can be ways to enable the eMMC after booting, but I am not familiar with how to do it. If you get an eMMC to USB adaptor, you can just re-flash it with a working image that way.
