What is FireFly [FF] operation mode

[Support]

FireFly [FF] operation mode is a quite special and unique way to repair damaged devices.

Ordinary boot (with factory DA or FDL files) can run only if hardware (CPU, FLASH, RAM) is completely Ok.
FireFly [FF] can boot even semi-dead (faulty hardware) devices even if FLASH chip and RAM are faulty.
So with FF mode you can connect to faulty device and make some kind of hardware tests.
