Hello!
So when i am sending to my STM32 0X7F i get ACK in return.
When i am sending 0x02 and 0xFD i get ACK in return.
The Problem start when i am trying to do mass extended erase like in the document named 'USART protocol used in the STM32 bootloader'.
I send 0x44 and 0xBB and get ACK like i am expecting, but when i send the 0xFFFF and 0x0000 i get in return 0x00 (not ACK and not NACK).

Are you sure that your serial comms has transmitted the 0x0000 correctly? Some code will stop at the first \0 in a char string, expecting this to be the end of the string.
I am just starting my attempt to make use of the Erase via USART1 of an STM32H743 and cannot find out what they mean by page numbers (the STM32H&43 has 2 Banks of 8 pages of 128 kB each)... are these pages 0-15... or what?
