Soft-Bricked FC

• If IMUF flash went wrong, plugin USB and wait 5 full minutes for recovery and re-flash IMUF.
• If cannot enter DFU mode, temporarily short-circuit the "boot" pads while plugging in USB, it should enter DFU.

Unable to flash flight-firmware via Configurator

• RX and USB both use same resources -- recommend soldering RX positive to 5v rail to avoid the need to disconnect RX.

HelioRC / ButterFlight is defunct

• EmuFlight flight firmware supports the HelioRC Spring FC and derivatives.
