Hi
Is it possible to change the pins of the bootloader that is loaded inside the chip? As I read it is only usart3 and only on PORTB. Thank you

Where are you reading this, and in what context? The pins are fixed, but you should be able to use USART1 (PA9/10), USART3 (PB10/11), USART3 (PC10/11) as well as CAN and USB options. The exact options will depend on the board design, the PA9 being a problem on the STM32F4-Discovery, but only because of the huge bulk capacitor attached to it by that design. See Table 22
