content: Hello and thank you for providing such a great forum. Lots of useful information throughout the whole site.I have found two other threads addressing this issue, but one is from 2014 and the other from 2016. I wasn't sure if it was proper to resurrect those threads, so here I am.I have an SDM3055 stuck on the boot screen that is black with white writing "Siglent-Siglent Technologies."The power turns on the fan and the DMM attempts to boot, but hangs on the boot screen.I have downloaded the updated firmware, but I am unable to find instructions for updating without access to the display.I have contacted support@siglent.com, per the instructions on their "After Sales" webpage.While I was waiting for a response, I was hoping perhaps someone here may have a suggestion.TIA for any replies and have a great day!

content: Wanted to follow up on this thread and report that it was a very easy fix. Siglent's support was very responsive and their instructions were very clear.Anyone who needs to perform this recovery . . . be sure you are using an 8GB or smaller USB stick and be sure to format it to FAT32. Those are really the only important details about the process.Thank you to all of you who stepped in to assist. Greatly appreciated.Take care and have a great day!

content: Hi everyone,Just to add my 2 cents to the conversation. I just got my brand new SDM3055. Really happy. Opened the box, checked the manual, plugged the beast, switched the power on and... can't get pass the splash screen!From what I found so far, it seems to be a known issue for the past... 4 years!!! Are you kidding me? Don't know when mine was "built" but "for those playing along at home" (pun intended!) S/N is SDM35FAC3R0271. According to Siglent's web site the lastest FW is from Nov 2019 and the previous one is from April 2018.I'm so not impressed.... First Siglent gear I ever bought and I'm probably not gonna get another one. I ordered this gear along with a with a SDG1032X which I haven't received yet because it is BO for next 2-3 week and I'm wondering if I'm not gonna cancel that.

The recovery file does NOT work (got the file right from Siglent).Does anyone have the correct voltages for the multi-cable that goes from the power supply to the main board?If it's not that, I will give up... not going to try troubleshooting the main board. I'll just buy another scope... and for sure a different brand!

content: I own a SDM3055 withSW Version: 1.01.01.16R2HW Version: 02-00-00-12-00I just wanted to make a FW update and found thefront USB not working. It is the second time i am using that USB interface, i had already done one FW update before. Therefore i guess it is a FW issue?I disassembled the device already but there is no obvious issue with the front USB, all 4 wires are working from front-connector to the main-PCB.I am wondering if an SD Card recovery might help?

content: Quote from: cnkz on February 06, 2021, 01:53:42 pmIt could be the USB stick you use.The SDM should first recognize a USB stick is connected and place a USB symbol on the display.Does it do this ? If not check with other USB sticks.USB sticks for FW updates need be formatted in FAT32 and 8GB or smaller.Copy the FW update .ADS file to the root of the drive and select it from the file manager and Open/Run it.

content: Seems my SDM 3055 joined the crowdI bought the unit in february in 2019, and it had the most up-to-date firmware then (I distinctly recall checking). I'm also fairly sure I updated the firmware at least once since then, which leads me to suspect I have at least 1.01.01.16R2 on it. However I'm not 100% certain.edit: never mind, didn't fully read the flashing instructions. Seems I need recovery package then?

content: Quote from: aheid on April 22, 2021, 09:43:18 pmThanks to some prompt and excellent assistance from tautech, the unit is now alive again.I ended up having to do the internal SD-card recovery route, not ideal. However, having gotten it back alive I noticed that the DMM did not recognize my USB drive!In Windows everything was just fine, and I repartitioned it several times, including a full "plain" partition (FAT32 all times).edit: after trying to use my brain for a bit, it hit me. The pen drive was using GPT. I followed this guide (using diskpart, GUI option was not available) to turn it back to MBR and now the DMM recognizes the USB drive.To upgrade the firmware I ended up using the same SD-card I used for recovery, but with a USB card reader. Somehow it wouldn't let me jump straight from the .19 version (from the recovery image) to the latest .22R1 version, had to do a trip via .20 first.:https://docs.microsoft.com/en-us/windows-server/storage/disk-management/change-a-gpt-disk-into-an-mbr-disk

I've read in this posting that the new firmware no longer does this so I'm guessing this unit must have been sitting in an Amazon warehouse for quite while.

content: Thanks @tautech, I tried the recovery on numerous USB sticks (all FAT32 formatted and less than 16GB), USB LED just flickers a few times at start-up then nothing, it still just sits there on the splash screen. You can see the green LED of the micro through the back panel slots and that is on solid flashing off twice about every second, so there is activity, not sure what it should be doing under normal operation or during boot(?).Has this recovery been tested with 1.01.01.25? I'm a bit sceptical that the last update (25) was to "Optimise the Flash R/W" ... has that had any effect on the ability to do a recovery? Has it made the hang more prone rather than fixing it?Any Idea's what else to try? I thought from the previous posts it would be fairly straight forward, but I'm not beaten yet!Can a recovery be done using the internal SD card slot? Is there a recovery package available for that? I guess that would wipe the calibration though!

So, I'm wondering where that is stored in the system files.NSP_System_Info.xml:<?xml version="1.0" encoding="UTF-8"?><nsp_system_info_root><device><system_information><serial_number><chip>SERIAL NUMBER GOES HERE</chip></serial_number></system_information></device></nsp_system_info_root>Also, My calibration file is empty:DMM_Calibration.xml:<?xml version="1.0" encoding="UTF-8"?><calibration/>Not sure if this is the user calibration or factory calibration?? If it's the latter, it would be good to know the format of the calibration data from a good file so I can get it baseline cal'd locally, although it doesn't look too bad calibration wise as-is.Thanks in advance!

content: BonjourI have this problem which appeared on my SDM3045x.At first, the screen was stuck on the Siglent logo, I called the after-sales service of the distributor who sent me by email with the recovery file (for version 5.01.01.03 or more)I used a 4G USB key but the boot didn't do anything, so suddenly I used an 8G micro SD card to attempt to boot from the main board PCB socket... and now the multimeter turns on with a black screen.- the LED of the analog card flashes 2x per second.-The microprocessor LED is on.I also noticed that the label of the analog card is noted "SDM3055X-E"the serial number of my SDM3045X is SDM34FAD2R1804 and the 3 year warranty has expired.1: Is the recovery file corrupted or not at the correct version ?2: Does the recovery file have to be different between a USB key and a µSD card ?3: Is it the main board that is dead ?I contacted SIGLENT France for an estimate of the cost of an intervention and I am waiting.Thanking you.Cordially

My U-disk recovery failed and left me with an SDM3055 with no model number, a serial number of 0123456789, and no calibration. I'm still waiting for Siglent technical support to give me any useful information. How did you get your model number and serial number back?

content: @HamDancer, post #12 in this thread shows you how to add/restore the Serial Number and Model Number.The calibration for my SDM3055 was supplied to me by the Siglent tech team after a conversation with them. They supplied it as a .bin file (from their production records). They also supplied a modified version of the latest firmware that allows the calibration .bin to be loaded in the same way you would import a firmware update file. Not sure why this can't be standard feature or at least give the user the ability to backup/restore this info up to/from a USB drive! I guess they need some work for the support team to do!My SDM3055 is now back to a good state with correct factory calibration.

The measurements are pretty good now; I don't have accurate enough equipment to determine whether or not they're perfect.

I can't find that anywhere on the internet related to instrumentation.Isn't the whole issue that you need a meter that is already more precise than the SDM3055 in order to do the calibration? Not to mention a power supply that can go to 1000V. That's not equipment that most people have available.And why didn't the resistance calibrate properly? That seems like a major problem...Thanks!-HD

Press the on/off button and keep it pressed while switching on the power supplyAfter this it would boot up and I could install the latest firmware.

I own a Siglent SDM 3055 who is stucked at boot screen.It's the second time it happened to me.The first time I contacted SIglent, and they sent ma a link to a "SDM3055 Recovery by U disk.zip" file that i downloaded, put its files on a 2 GB FAT32 USB disk, and was able to recover my unit from that.I then installed a more recent firmware (may be the 1.01.01.20...).But it just happened again yesterday : freeze at boot screen, after the unit stayed without power cable connected for some days.The bad new is that the recovery USB disk trick don't seems to work anymore ! The 3055 just read quickly the USB disk at startup, but no recovery happens, and it stays frozen...So what to do ? Maybe you have some useful informations to help me with this challenge ?By advance, thank you ! Regards.

What is needed to use this kind of memory for long term storage is error-correction (redundant) data and regular refresh of the data. If this isn't implemented correctly, a device is likely to fail due to the flash contents getting corrupted over time.

content: I received email from Siglent support team. Recovery files doesn't work. I tried with several pen drives with various capacity and it do nothing. I have next SDS1052DL+ bricked. It happened exactly like with previous one. Yesterday everything was correct and today oscilloscope was stuck on boot menu. I tried with the recovery files but it also doesn't work. We have 7 item of SDS1052DL+ in our university that was bought about 8 years ago. I also opened cover of this oscilloscope. On the main board I found micro SD card slot but it also doesn't provide recovery function. I wrote about it to Siglent but they didn't respond. What can I do?

When I power up the unit the power indicator goes from flashing to solid green, the fan spins up, and the boot logo screen appears, and that all it does. Unplugging the unit and powering back up had no effect, it still stops at the boot logo screen.TauTech, it seems from numerous other post that you hold the keys to a possible solution for this problem. Can you assist?Thanks in advance for any assistance with this issue!Mike

It is the first time that i have a lab meter with such a problem only after 7 years (in 40 years).SDM3045X upgraded to fimware 2.01.01.12 if i'm right a couple years ago.Any chance to recover it ? I think that it is probably a dead SD card.How to avoid this in the future ? Is it possible to make a copy of this card, or put a better quality Sandisk or similar SD card ?Last, i've always found this multimeter very slow to boot. If i need to replace it, what brand would you advice to get a faster boot ? If i need to buy another device, i will probably upgrade to a 6 1/2 digit at the same time.Thanks for helping, bests, Olivier.

content: Thanks for the suggestion. I got the recovery pack from there already, but no success yet. The suprising fact is that the recovery does not even work on a second fully functional SDM3055 (bought at the very same time, so most certainly same hw revision). On both devices, activity LED of USB stick lights up briefly after power up, on the working one boot continues normally and USB stick is detected as expected after boot completed as normal USB drive, no effect on installed firmware. On the defective one, the logo shows up properly for a few seconds, then it reappers inverted, upside down and replicated horizontally, no matter whether recovery stick is inserted or not.Already tried various sticks from 1 to 32 GByte, formatted via the formatter fromhttps://www.sdcard.org/downloads/formatter/and Linux mkfs in various ways ... There must be some very special setting or property of the stick for the recovery to work.

No recovery.Siglent now says I have to send the device in for repair.This is extremely annoying, as it has less than 100 hours of runtime as a backup device during the last six years.My questions are:Does recoveryV1.01.01.19make sense ifV1.01.01.25was installed on my device?Does it make sense to test a newer recovery version?If so, where can I get it?Is SD card recovery possiblewithoutdeleting the factory calibration?It does not make sense for me to have an uncalibrated 5-Digit multimeter

content: An important point for recovery from an SD CARD. In addition to the fact that the primary partition should be no more than 4 GB, it is important that the drive is not for an EFI system, but for an MBR. The section should be active, but I'm not sure what's important, because it's highlighted in my notes. But often in recent years, the SD-CARD, after various manipulations with it, turns out to be in EFI format. In this case, it will not be recognized by the SD3055 device. It's not difficult to do it right. Depending on the version, you may lose calibration files.Under Windows, run the command with administrator rightsdiskpart.exeNextlist diskfind the necessary driveselect disk nwhere n is the number from the list given by the previous command!!! Attention The selected drive will be logically cleared. Carefully look at which number "n" you specifiedclearconvert MBRcreate primary partition size=1024select partition 1activateformat fs=FAT32 quickCopy the necessary files for recovery.Disconnect the multimeter from the power supplyInsert the card into the slotInstall a temporary jumper between the J16 pins (?

This known Bug was fixed in V1.01.01.20R1,I can not remember that problem after 20R1 up to my last loaded V25 firmware!Does anyone have the same problem with V1...27R2?2)Does it make sensealwaysupdating to V1.2?My digital board is Rev. SDY8.007.075F, does it need the EMMC flash support of V1.02?3)V1.02 Rev.History says: After upgrading to version V1.02, you cannot return to versionV 1.01!Does a recovery with V1.01 work on a board that had V1.02 installed?Unfortunately, I haven't found any answers to these questions at Siglent.

content: It should also be possible to connect via COM. It is on the board, it is necessary to put a connector through the COM <-> USB converter, but I did not do this. I saw it from our friend from France in the hack sdm topic.

content: Current status. I'm tired and joking. What's in the photo? Is this negative differential resistance? No, this is setting zero in the calibration file at a slightly +- different temperature.Special thanks to tautech for their quick support and sincere involvement in our problems.

content: Quote from: Inovet on September 11, 2025, 07:52:59 pmUpdate from my weekend work:The sd-recover was complete successful!As stated before by tautech - the factory calibration has been retained.After updating to V1.01.01.27R2, I backed up the calibration file via telnet.(/usr/bin/siglent/firmdata0/DMM_calibration.xml).Now I am much more relaxed!Out of pure interest:Could a factory calibration file be copied to the user directory or vice versa?The names are identical, but are the files for factory and user calibration identical in structure?I haven't performed a user calibration yet, so I have no user cal file for a compare.Actually, I am very happy with telnet.....Does versionV1.02.01.27R2 really have a buggy or non-working telnet?No bug fix is listed for V1.02.01.28.What bug is known inV1.01.01.27R2?I will only update to V1.02 when I know for sure that telnet port 23 works.....there is no (official?) way going back to V1.01!
