Update the firmware of my choice, that ok with you?
You care if I'm OK with that? That would have been nice.
Though it sounded like you were aggressive for no reason.
I was hoping you were making some reverse engineering, and looking for something in particular, something you were hoping might be found in the past versions, that's why I've asked what for do you need them.
can not update the scope to an older firmware version
It is possible to downgrade, or to load arbitrary FW version. Did that once, only to realize the previous FW version that I thought it was better has heaving the same behavior, so reverted back to the latest firmware.
In order to downgrade, you'll have to make a Rigol-signed disk, it is attached in this post:
https://www.eevblog.com/forum/testgear/new-rigol-ds1054z-oscilloscope/msg3613778/#msg3613778How to make one, then how to use the attached "Rigol_sign_disk.zip" (in order to make the oscilloscope to accept any arbitrary firmware version) is at the very end of that link, posted as code. That disk will spare you of manually editing the version, and/or to recalculate the checksums of the .gel file.
