Most of users change old version processor (F1) on faster F3 or even F4. Today I'll describe  Seriously Pro Racing F3 - clone.

WARNING!  

In this set of pairs for Vbat and Buzzer look on site of cables in connector because can be send like I revived

 And can be by mistake polarity in board see manual 8 and 9:

When you will want change software there is no chance to go via usb. You need to use boot headers to starting flash firmware. 

Set  no reboot sequence 

set flash on connect

set full chip erase

set manual baud rate on 115200

Download firmware from cleanflight site here for SPF3.

Push button local firmware -> look you file .hex for SPF3 -> and now you can connect board to PC.

On right site you can see boot pins - short them and click - > LOAD FIRMWARE 

When you will see green strip with flashing process you can remove short connection from board.
