Bricked Parrot Airborne Night minidrone?

[diffused0233]

I have been messing with the firmware for the mini drone series. I have been creating a tool to be able to dump the PLF format and repack it to run custom firmware on the Parrot Airborne Night. However, I failed to look for a fail safe beforehand, and now I think my drone is potentially bricked? When I boot it up, it's stuck on two orange lights, which typically you would only see for a brief moment during the boot process. Is anyone aware of any way to reset the device?

I've tried the following:

1. Trying to factory reset

In the file system the drone has a script called verylongpress_0.sh to factory reset it, so I tried holding the power button for a long time... and nothing.

2. Debug mode

There is another script called shortpress_4.sh that switches to USB debug mode with serial console and debug disk image when you click the power button 4 times.

Have you tried DFU mode or is that what you are calling debug mode?

Access DFU mode: This often involves locating a small "boot" button or specific pads on the flight controller board and holding it down while connecting the device to a computer via a USB cable.

Sorry, just found the time to respond. I checked the rootfs and saw USB/debug scripts (what I meant by debug mode) and a kernel console on ttyPA1, so I doubted they left no recovery path. Like you said, it's probably DFU over USB or an internal UART. I am not a hardware person and might be out of my depth, but I will look for a BOOT or UART pad since plugging the drone into my computer isn't showing up.
