Hey guys, wow! Thanks what a beautiful procedure you guys created for us. THANKS! I had trouble at first, it was because I plugged into the computer instead of the router. Also, Putty has lots of options, I had no idea what to put where. So I installed Telnet from "Turn Windows features on or off" and pasted "Telnet 192.168.1.28 10101" in a Administered command prompt and I was in!
Yes! to 120M!

This procedure worked great for me I also have the software version 2.01.01.23R8, I just follow the instructions step by step and I used step 10 as described by this op ":wq". Good luck and thanks for the awesome post by all, everyone is so responsive on here. I have no idea of what I'm doing but I follow the steps and everything works. thanks again.

Thanks so much John this process worked for me.
I had
Two small things:
When you click the firmware link it doesn't work so copy and paste it into your web browser address bar and remove the comma at the end.

Step 10 should read:
10) computer console, press the ESC key, then type: ":wq" and <RETURN> to save the file

The : in front of the wq is important as it does not work otherwise.

recap the steps scattered around to here.

----------------------------------------------------------------------------------------
1) SDG2042X: utility->system->system info, note down your Serial number and Software version. for example: 2.01.01.23R8
2) USB drive: format USB drive to FAT format, with MBR (master boot record) scheme. If you use GUID scheme, SDG2402X will not recognize it. It tells you it is removing media drive even you are inserting it in.
3) Firmware: goto https://www.eevblog.com/forum/testgear/siglent-ads-firmware-file-format/msg1870091/#msg1870091, and download telnet_SDG2000X.zip, unzip to telnet_SDG2000X.ADS, put it on USB drive
4) SDG2042X: hook Ethernet cable, turn on SDG2042X, utility->interface->LAN Setup->DHCP on, write down IP address, for example: 192.168.1.20
5) SDG2042X: Insert USB Stick into front panel USB socket, put SDG2042X to utility->/System/Firmware Upgrade->USB0->find file: telnet_SDG2000X.ADS->Recall, updating starts and fails after a while. Yes, it fails. So your version is never changed.
6) SDG2042X: LEAVE POWER ON SDG
7) computer console: access to SDG2042X file. type: telnet <SDG IP address> <SPACE> 10101 <RETURN>, for example: telnet 192.168.1.20 10101
6) computer console, mount driver as writable. type: mount -o remount,rw ubi2_0 /usr/bin/siglent/firmdata0
7) computer console, make a backup. type: cp /usr/bin/siglent/firmdata0/NSP_system_info.xml /usr/bin/siglent/firmdata0/NSP_system_info.xml.orig
computer console, use "vi" editor to edit one file. type: vi /usr/bin/siglent/firmdata0/NSP_system_info.xml
9) computer console, move cursor down by typing "j", and right by "l" to the very first letter "<" of the line <license> and press "x" to delete anything between and including "<license>" and "</license>". After deletion, this line becomes only has "</system_information>". if anything goes wrong, you could exit "vi" editor by "esc" and ":", and "q!", and redo it again.
10) computer console, press the ESC key, then type: "wq" and <RETURN> to save the file
11) remote computer console, type: "sync"
12) SDG2042X: remove USB stick
13) SDG2042X: turn power OFF
14) SDG2042X: check utility->system->system info, and check product type and Serial Number

Just confirming that this still works.
I just bought a SDG 2042X (December 2020).
It came with FW 2.01.01.35R3B2, and it is still hackable using the procedure above.

bdymek · « **Reply #103 on:** January 07, 2021, 09:58:22 pm »

Double-confirming SDG2042x->SDG2122x instructions and .ADS works.

carlitos49 · « **Reply #104 on:** January 12, 2021, 04:21:42 pm »

Hi, I just purchased a SDG2042X, downloaded the "telnet_SDG2000X.ADS" and installed it on to a thumb drive plugged in into generator and loaded the "telnet_SDG2000X.ADS" file as a firmware update until it showed me it failed. I then followed the instructions as shown on this forum step by step but I keep getting kicked out of the telnet session as connection refused! on putty. I am using port 21 which is what is shown here but so far I have not been able to get in. My firmware is: 2.01.01.35R3B2 which I believe is the same that has worked for others. Any hints or recommendations will be greatly appreciated.....Thank you!

Looks like the instructions specify port 10101:

for example: telnet 192.168.1.20 10101

13) SDG2042X: turn power OFF
14) SDG2042X: check utility->system->system info, and check product type and Serial Number

Step 14 is not possible. The power is off. What do I do now?

(excellent instructions, by the way. That telnet trick could be really handy)

carlitos49 · « **Reply #107 on:** January 13, 2021, 01:37:56 pm »

Yes, I was using decimal port 21 instead of 10101......I thought they both represent the same? but I guess not. Also I have never used linux and don't know anything about the shortcuts for editing, so even when I was able to establish the root session any changes that I did on my text editing would not get saved. It took me a while to figure out that to save and quit you have to use. ":wq!" I was using exactly what the posted instruction showed which is: "wq!" missing the colon. Once I realized that after a few scary trials I was able to get the hack to work for 120 MHz

Which number system would represent decimal 21 as "10101"?

Coffee can only go so far in offsetting the effects of the massive party and subsequent hangover you clearly had ...

Just bought a SDG2042X and liberated it using the usb file trick.

It came with software: 2.01.01.35R3B2 and hardware 02-02-00-40-00

After liberation, the firmware has not been touched and the product type has been changed to: SDG2122X

Thank you all!

The thing has a noisy fan. Any suggestions?

Replace with Noctua NF-A6x25 FLX (you will need to replace the connector from the noctua fan with the connector from the original fan)
You can still hear the fan, but less noisy

Blue · « **Reply #113 on:** March 23, 2021, 05:20:16 pm »

Nailig, many thanks.

I'll look into it.

Just ordered one...

Blue · « **Reply #114 on:** March 29, 2021, 06:01:13 am »

I installed the Noctua NF-A6x25 FLX and it has two working fan settings. I used the lowest one and it works great!

Nailig many thanks.

I picked up a SDG2042X over the weekend. I've just updated the BW to 120. Awesome sauce! Many thanks to y'all, particularly, John95 and TV84. Excellent hack.

xzswq21 · « **Reply #116 on:** June 08, 2021, 08:40:19 pm »

If I hack my SDG2042X what will happen to the calibration of the signal generator? Actually I want to test some kits and report the results. Thanks

Software version: 2.01.01.35R3B2
Hardware version: 02-02-00-40-00

Blue · « **Reply #117 on:** June 09, 2021, 12:42:57 am »

Hi xzswq21,

Just do it. No problem with calibration that I've noticed.

phecap · « **Reply #118 on:** November 16, 2021, 01:51:39 pm »

Shortly after I bought the SDG2042x in 2017, I successfully applied the old hack.
The info now shows:

Software Version: 2.01.01.23R7
Hardware Version: 02-01-00-35-00
Product Type: SDG2122X
Serial No: 0123456789

Now I would like to update to the latest firmware version 2.01.01.35R3B2.
Is this possible without the SDG falling back to the 40MHz version SDG2042x?
Or should I apply the new hack after the update as described in this thread?

tv84 · « **Reply #119 on:** November 16, 2021, 03:09:20 pm »

What is the old method?

phecap · « **Reply #120 on:** November 16, 2021, 03:22:09 pm »

With firmware version 2.01.01.17R5 and older it didn't need a telnet password for the hack.
See the first page of this thread.

bicycleguy · « **Reply #121 on:** November 18, 2021, 06:02:28 am »

I updated from 2.01.01.23R8 back in Dec. 2018 and updated to 2.01.01.35R3B2 when ever that came out without problems.

Unfortunately the update doesn't fix any of the numerous software usability problems. Sometimes I wonder if I got conned into thinking the 'free' no warranty upgrade justified the purchase. I'm constantly fighting little glitches that I think are in a DUT but turn out to be the SDG2042x not working as expected.

phecap · « **Reply #122 on:** November 23, 2021, 08:50:42 am »

Thanks,
I have updated the firmware of my SDG2042X from version 2.01.01.23R7 to version 2.01.01.35R3B2.
Everything still works and I still have product type SDG2122X (120 MHz).

core · « **Reply #123 on:** December 15, 2021, 08:09:07 pm »

I have a new SDG2042X, arrived with firmware 2.01.01.35R3B2.
The 14 steps procedure is still working, everything was fine, now it's a SDG2122X.
Thanks !

I just purchased. Same firmware as above.
I was also able to update to SDG2122X using the 14 steps found here: https://www.eevblog.com/forum/testgear/siglent-sdg2042x-hack-door-closed/msg2409867/#msg2409867
