Siglent SDM3045X - Enough is enough

How would be the steps to revert from a hacked 3055X-E back to the 3045X?

Maybe, my question was not clear enough.

If I hack my 3045X to the 3055X-E with the modified 3055X-E firmware and for some reason want to revert to the 3045X, what are the steps?
Is it sufficient to simply install the normal (unmodified) 3045X firmware update?

Your question was clear, my answer seems not.

You can only flash a 3045X FW again if I change its ProdID previously. If not, the machine will reject the FW package.

If the hacked  3055 FW has the 3045 ID to run on the 3045, it could well work with just a normal firmware update to the original 3045. We don't know the details and thus the rather good question on how to get possibly back, just in case (e.g. if you want to sell the meter).
It may work with the original FW, or it may need a slightly patched one.

Another similar question is, if there is a future SDM3055 FW update, how to apply this to the hacked meter ?

Hopefully just install the new 3055X-E version:

If it is "hacked" you can only install 3055X-E FW as tautech said.

Edit: Here is the reversing instruction.

That link is not working for me, first the page changes to int.siglent.com main page and then to www.siglenteu.com.

That's what some browsers do. 
Go back to the int.siglent.com page and select the Chinese website from the globe pop down in the top right corner.
The current 3055X-E firmware is linked a page or 2 back in this thread and it downloads to your browsers download folder.

Still doesn't work properly i.e. switch to Chinese. Your direct link for the firmware file does work. I have tried Edge, Chrome, Firefox all have the same issue.

But after some trying I noticed if I use the url below, I can get directly to the Chinese site and can browse there to the SDM3055X-E page and from there to the firmware page.

Works fine with Chrome here so must be browser settings redirecting you......a reason why I never let them auto translate but instead manually translate anything I can't read.
The Chinese Siglent website used to be notorious for redirecting you to an English version however none of them show the juicy new products that are coming our way.

Thank you!

Can you give a one-liner explanation of what the patch does?
Could it be that it describes a set of criteria for its suitability?

Yes, the FW version must match the HW and the OS checks if the FW version is the correct one. The patch fools the OS to believe the FW version is correct so it then goes on to load it.

What about product id in the system info page? It still shows 3045. Were the .xml files uploaded here not the correct ones for tv84 to make a patch for it?

My XML files are probably useless, as if you open them, you will see no information about the model number, thus it has to be stored somewhere else.

I think tv84 asked for file named NSP_system_info.xml and that was not in your zip. How do you access your 3045's file system? (I haven't connected it to usb or network.)

There is also the info on how to backup the calibration data.

OK, here are the files from the other directory including NSP_system_info.xml.
Though there is just a serial # in there (I changed the last numbers into '0' as probably not important).
This Zip also includes the calibration data. It shows that indeed the calibration borders are "2" and not "6", thus there should be no problem by using the 3055x-e firmware.

Exactly. Thanks for sharing.

So, the the model name needs to be changed in the NSP_trends_config_info.xml.

To be totally correct it would be good to see this file content in an official 3055X-E.

That's what some browsers do. 

No, the redirect is what the server sends. This may be based on UserAgent settings or similar, but it is never a browser decision. The browser decision is to either display the error or follow the redirect. You can clearly see this in my wget trace.

How can you get filesystem access and/or telnet on the dmm?

I've tested post #14 from linked thread on a SDM3045X with latest v5.01.01.07R1, with a 4GB FAT32 clean USB stick, but couldn't get past step 2 - any TCP connection on standard telnet port 23 is refused, while on the other open ports (111, 732, 5025) they drop instantly.
Any hints are greatly appreciated.

Ok, thanks.
Tried the attached FW file, but any flashing attempts results in 'update failed'... Are there any special steps to be taken for flashing - especially since the unit may see it as a version downgrade?
