Arduino Mega 1280 - unable to program ( bootloader )

rat-:
Hi

I can confirm that it works.
Today I uploaded a new bootloader to the old Mega with using Usbasp programmer and now the watchdog works fine XD

But I have question, it is possible to change the upload speed to the old value 57600, Now I have to used this:

mega.upload.speed=115200

I'm guessing that this speed is stored in the new bootloader, there is any easy way to change it ?

No easy way. The bootloader program is compiled with a fixed baud rate and to change optiboot to 57600 would require the bootloader source code to be edited and recompiled, which is not something you can do in the Arduino IDE environment.
