2.3 is the latest firmware AFAIK so if your board has that there is no need to upgrade. What do you mean by it doesnt fly? Is it unstable, not arming at all , not enough power etc?

Can you put up in detail what have you done till now chronologically with a pic of your setup?

Some more questions which can help you out:

Have you uploaded sketch with correct configuration?
Have you calibrated radio,esc,acc,mag and covered the baro?
Have you set flight modes?
Have you correctly set up props and motors and frame orientation?
Have you tuned PID's?

may be

the weight of your quad is too much
the props used are not matching motors specs.
amps of esc are low
thrust of motors low
or even the battery cant draw enough amps/volts

can you post all the parts list
