The following link for the previous official firmware is no longer exist.  Anyway to get the older (and hackable) firmware?

EU website.

How about this one

There is no old firmware, at least I didn't found it.
I have a copy of SDG2000X-P17R5 and SDG2000_eevblog_23R7. Just write me PM if you're still need it.

Keep in mind that the newest firmware, 23R7, has a USB recovery mode, for use in case of corrupt software. The older versions do not have that, and the enclosure must be disassembled in order to un-brick them.

I keep a backup of all these versions:

https://www.eevblog.com/forum/testgear/siglent-ads-firmware-file-format/msg1335892/#msg1335892 and newer ones.

For that model the only missing is 2.01.01.12R1.

I just got my brand-new SDG2042X and the Firmware says 23R8 !
Interestingly the latest Firmware I can find online at any Siglent Site is 23R7.
Thus, I am scared to downgrade to find out that my hardware version needs 23R8. And I don't have 23R8 as an install file to go back.
Is there a way to archive the existing loaded Firmware?

IIRC, at least for some devices, Siglent has firmware downloads in multiple pages (and not talking only about different market sites like USA vs. EU), and there can be differences which versions are listed in which page. Might be worth it to browse/google around, just in case, the latest firmware might be there somewhere...

It's not !
We often see new products with FW that has yet to be publicly released and when it is it's most often a newer version again. We just wait for it to be available.
All the FW versions are on the Shenzhen site.

Maintain your version! There will be a way or wait until the version is publicly available.

Did anybody find out if it works with the newest firmware 23R8 ?
How about if you downgrade to 23R7?

Are there any hints that the hardware was changed, as to limit it not only in software, but hardware as well?

I don't believe that would happen on just a release change R7->R8. I think that would deserve (at least) a minor change in version number.

I don't understand what's the problem with having the new version.

If it's really important I can help Lazyengineer make a total NANDdump backup.

Thanks. It was just to help deciding whether I will buy it or not.

I contacted Siglent about this, they told me that 23R8 is identical to 23R7... I don't know If I have to believe that.

Anyway, backing up firmware or NAND would be interesting... How would you do it?

Thanks

I just spent several hours trying to hack my 2042x. It came with R7 firmware so I tried downgrading to several earlier versions all the way back to P21R2 (released 6-17-2016). Every version still wanted a login and password. I then noticed that in the bug fix list that it states that once the FW is updated to version 2.01.01.17R5, then the FW can no longer be downgraded. So even though after I did my downgrades the SDG 2042x showed the downgraded version was installed, telnet still opened with a login prompt.

Does anyone know how to get past this? I suppose it is too much to hope that someone has cracked the login and pass word.

JaneKivi,

The tinyurl link says the file has been deleted. Also, a link to firmware updates for all the instruments still works :

* telnet_SDG1000X.zip (223.97 kB - downloaded 294 times.)
* telnet_SDG2000X.zip (223.97 kB - downloaded 477 times.)
* telnet_SDM3045X.zip (223.97 kB - downloaded 149 times.)
* telnet_SDM3055.zip (223.96 kB - downloaded 154 times.)
* telnet_SDG6000X.zip (223.97 kB - downloaded 177 times.)
* telnet_SDM3065X.zip (223.97 kB - downloaded 142 times.)

BUT, when I try to install it, the progress bar gets to 90%, then the SDG2042X indicates the update has failed.

I note other users perform a reboot and can log-in, but my SDG2042X rejects the login that should be allowed by the telnet file.

I have also read in other places on this forum that the login can be done with the latest firmware (23R8), which my unit has from the factory.

I don't see many recent posts, so I'm wondering what I'm missing. I would expect this unit to be very popular, so I'm inclined to believe that I'm missing something others have gotten right.

Can you provide any help?

Best Regards,
Shane

And what is idea to boot it...

You did not read information. First need learn and it need carefully read enough information. And even more important - before you do any changes inside system. There is not "user manual" for this except if you use this forum like user manual... then can say "RTFM"

One tiny tip (you find more and it need your own work ;) )
Read this tip and think if the lamp lights up... ;)
If practice and theory is not equal it tells that used application of theory is wrong or the theory itself is wrong.

Hi RF-Loop,

Thank you for your reply.

I did read all these items, and I even saw your original post prior to you copying it for me to read here.

The ADS information you linked to appears to have more to do with getting access to a scope, than getting access to the generator.

I tried port 22 (saw that in a YouTube video) which worked for the YouTuber, but I get a connection refused if I use that port. 10101 = 21 in my binary to decimal book (16 + 4 + 1), and that port doesn't work either.

I am using a Mac, so I'm using a command line version of telnet, not a GUI, so perhaps I am missing some configuration item there ( I use telnet 192.168.xx.yy <portnum> syntax to open telnet session)

I am not able to discern whatever subtlety your re-post is implying. I could use a differently phrased hint, if you have one. (I am not normally dense, so I apologize for my lack of lucidity here)

If not, I thank you for your time and trouble responding to my initial post.


Best Regards,
Shane

Hi, ShaneEEV,

Thanks for the post. The information is scattered around in the messages and you have posted the best summary. I noticed that you also have corrected the SN number issue (#9) in your steps. I know your starting point is 23R8. Only two items are missing from your post.

1) where to get downgrade file and how to downgrade?
2) how to upgrade back to latest version?

Thanks again. I will try to buy one. Everywhere it is sold at list pricer ($499, ie. amazon.com). anywhere to get it cheap?

---------
I found the answer:
just download an earlier version posted several message up (15R2 or 16R2), and unzip, it has an updating instruction.
