Rescue flash

WARNING: This will reset all your OSD settings!!!

If you have no OSD or the red LED does not flash or just stays on you can try the following to get your OSD back:

1. Bridge the SDA and GND pads
2. Connect a Lipo
3. Remove the SDA-GND bridge
4. Connect USB
5. Start GUI and select "Full chip erase"
6. Flash FW

In most cases this will bring everything back to its original state. You will have to setup your OSD again though, all settings have been reset to defaults.
