upgrade New Rigol DS1054Z oscilloscope to firmware 00.04.03.SP2?

Yes, but:

"DSFR enables everything including that 500uV Vertical option but the scope won't work properly with it (check other thread for details)
DSER will enable everything BUT the 500uV Vertical option so thats the option to choose"
