1- Download the pathed firmware from the first post of the this thread:
https://www.eevblog.com/forum/testgear/rigol-ds1000z-firmware-patch-plugins/msg1467130/#msg1467130 . 
You have to download the two splited files, rename their extension to “rar” and extract the DS1000ZUpdate.GEL file out of the archive.

Hi,

My DS1104ZPlus has fw version 00.04.04.03.05 and the patched firmware is 00.04.04.03.02 so I think the instrument do not allow to downgrade, right?
How can we overcome this?

Or am I missing something?

You can change the patched firmware version code and its CRC value to match the new version number. The details are all in a separate topic about Rigol .GEL file reverse engineering.

Thanks but that is pretty much difficult for me to figure out how to do it without any other info.
Any link? or even the topic's name?

Even though, IMHO if that is the only solution, then there is indeed a major problem if we want to move on with konnor's solution.

You can find the details here:

However I'll try to patch the latest version with konnor's stuff and post it on the same thread.
