Bootloader 00.06.02 attached.
KedasProbe:
I haven't updated it yet, I got this answer from Rigol:

--- Quote ---Generally speaking, we do not recommend the upgrade of the DG4000 firmware with series before 00.01.08.002 or the keyboard version before 05.01.
After upgrading the DG4000 using the bootloader program, the calibration data will be cleared, and the unit needs to be recalibrated. This cannot be completed on the customer side, as bootloaders are usually not directly developed for the customer's use.

However, if customers emphasize on upgrading the firmware, the unit will have to be returned for replacing the DG4000 mainboard. This will imply a charge of the service.

So I would lose calibration data when I load the bootloader, but not sure why the mainboard would need replacing.

I can't update the firmware from version 1.09 to the modified 1.08.  Can anyone give me an exactly working modified version?

Is your bootloader v06? If not, update the bootloader before trying the patched version.
