New Defect: P2 and H3-3D

I thought you can only brick it if you remove power before re-applying the firmware. Without a bootloader, you can't upload firmware. I may start with the Naza but I think the same rule applies. Once you wipe the NV ram, you can't kill the power before applying the new firmware.

That's quite possible, I can't say for sure if I had power cycled before trying to reinstall the firmware...I didn't think I had but it was a few months ago and I haven't tried it on another since. The good news (of sorts) is that if it does brick, replacing that board with a known good one will resurrect it.

p.s. hope you've made it off the tarmac by now
