You make it yourself, it's just a USB drive formatted in a particular way with a specific file on it.  Use any old or new USB drive and follow the instructions in this post which is all of 1 page back.

Sweet! Where did you get those labels from?

Hello Gandalf:  For information on how I added Labels and Color to my PD832 to DP832A conversion Front Panel please see ->    https://www.eevblog.com/forum/testgear/need-help-hacking-dp832-for-multicolour-option/msg2540175/#msg2540175

Thanks for the info on the USB Image file that you provided a path to for me.  It hasn't helped, but I don't know if the USB Disk Image is the problem.  Or if it is just that the hack for the DM3058E doesn't do anything, which I kind of expected before (that it wouldn't work).  I have to play with this some more, and also see if I can reformat (low level of course) the USB drive back to its original 256 GB.  Right now its total capacity is at about 31 MB.  So the image must have been 31 MB, although the size of the image file itself was around 16.4 MB.  I know that this is what happens when you transfer a disk image file to a USB drive, so I'm not concerned.  But as I said I don't know if the image process worked properly yet.

Thanks for your assistance, Ted

Edit: Added Link for information about using Sharpie Permanent Color Markers for adding LCD matching colors, etc, and nothing requires disassembly.

@ted572
You're welcome.  If the USB drive reads and has a single file on it then it's almost certainly good and not the reason things aren't working for you.  Mine worked in a DG1022Z and DP832.  If you issue the model command via tenet and get a message like "unrecognized command" on the screen on the screen of device you're trying to upgrade but do get responses to *IDN? then it's probably a bad USB drive - maybe one that the device doesn't like for some reason.  However, a drive you created from the disk image is more likely to work than one you created yourself by formatting and copying the file to the drive.

I don't know if it's possible to upgrade a DM3058E using the USB method, has anyone else done that?

TurboTom:
The DM3068 DMM's digital circuitry is built around an Analog Devices Blackfin DSP, I assume it's a similar situation with the DM3058(E). It appears that only Rigol's more recent gear that's based on the Freescale/NXP i.MX or Texas Instrument Sitara ARM Core SOCs can be accessed via the "Magic Stick" method. So your attempts to "talk to" your DM3058E may be futile...  :(
