Flash Update

• Flash is write-protected, phack (main.c) needed to be modified to make it works.
• Good news : the whole flash can be written (not only segment 0)

       for (x=0; x<2; x++) {
	    sendcmd(f,3,x|0x80000000,0x8000,0);
	    y=read(o,buff,0x8000);
	    write_data(f,buff,0x8000);
	    sendcmd(f,2,x|0x80000000,0x8000,0);
	    read_data(f,buff,0x200);
	    if (y!=0x8000) {
		printf("Premature file end. Hope everything still works OK.\n");
		x=9999;
	    }
