content: Haven't turned it on for a while, but today I fired it up and it is hanging at the Siglent boot screen. I do have the latest firmware installed: SDM3045X_5.01.01.03 which is supposed to support a USB recovery. However, I'm not sure I know the procedure for doing it?Help me tautech, you're my only hope!

content: Sure I will.Great you have the latest FW installed that supports recovery, that makes it much simpler.I have to request the recovery package from the factory or you could from Siglent USA but I'll have it faster than them unless they have on file....they probably do. (I don't yet have the SDM recovery package)It'll most probably be a link to a download package (zipped or rar'ed) including specific instruction to place the files in the root sector of your thumb drive.....so clean one in readiness.I still have your email Bill so I can send the link or file direct to you.Important note:It is only provided on the understanding it is NOT made public otherwise your unit must go to an authorized repair center.I should have something in ~8hrs when they're up and running for Monday morning.

content: Quote from: BillB on May 24, 2018, 10:45:05 pmI thought about that issue the last few days (since a few people had troubles updating the OS in their SDS1004X-E) and have a strong suspicion - it's most likely an USB stick compatibility issue after all.While the instruments seem to handle most USB sticks just fine during regular operation (as long as they are FAT16/32 format), the boot loader is a completely different piece of software that uses more basic device drivers and might be more picky.I don't know what USB sticks you have tried, but from my experience, Transcend works absolutely reliable and I would expect the same for SanDisk (cannot test this because I don't have an alternative OS version for the SDS1004X-E). If you haven't tried one of these, it might be worth doing so first, before sending the unit anywhere.

content: Quote from: Performa01 on May 25, 2018, 02:36:05 am(I also believe it's a USB stick problem...)Let's try to understand this in a more scientific way:As Performa01 suggests, it definitely can be (or is) a problem in the way the sticks's USB controller handles the scope's requests. The scopes usually use several raw-access routines which may not be correctly handled by the controller.For example, in the DS1054Z, Rigol tries to read explicit boot sectors to see if the stick is a "special vendor USB stick" which triggers special options/access rights. Those raw boot sector access routines are not used anywhere else in the scope, only on USB boot/insert.I suggest you all to use the ChipGenius (http://www.usbdev.ru/files/chipgenius/) software to see which is the controller/fw version of your stick and to establish a compatibility table with these scopes.And, when you mention sticks that work or not work, include that controller reference so that we try to map the valid ones.

content: Quote from: tv84 on May 25, 2018, 09:39:04 amYes I strongly suspect you are right.For something like an OS upgrade or in this case a boot recovery where files are accessed from the stick very early in the boot process I've always taken the precaution of using a freshly formatted stick.Did you try this Bill ?

content: My first attempt was with a Transcend 32GB flash drive that did work for the OS update on SDS1104X-E (even though I knew that the SDM3045X instructions said that 16GB drives wouldn't work I figured what the heck) and that didn't work. Then I tried a FAT16 formatted, generic 2GB flash drive, and that did not work either. Unfortunately, while I have lots of other flash drives, they are all 16GB or larger. For giggles, I tried a 16GB Corsair formatted as EXFAT, and that didn't work either.I know that with some other embedded linux systems I've worked with, the ROM boot loader was particular about the MLO (x-loader) being the first file on the device, so I even made sure that was the case.I've got an RMA from Siglent America, so it's going into a box tonight.

I have cycled the power a few times and unplugged the ethernet connection and still only the logo shows. I have going in circles with trying to find any support for this meter.Is there any kind of key combination or recovery tool to fix this?

content: Hi allI see I'm not alone with this hanging boot issue, I've got 2 of these units brought around the same time so probably from the same production run.Mine are very low hours use but one I've kept at the workshop has been playing up for a while. It was hanging on cold starts with the Siglent logo, if it was left alone eventually it would get there and be usable.Been using it to test some stuff in production using the limits and bar graph display of late and sometimes it would just lock up.Power cycling from the from panel would clear the problem until it happened again at some point, its very random. Just put that down to a bug with that combination of display setup..Since yesterday now it boots up into the measurement screen but hangs immediately.I brought these in Feb / Mar 2019 so warranties gone but this was playing during the 3 years(?) it was covered, but with Covid hitting lost a few years to deal with it at the time....So maybe corrupted firmware? It had been updated to the latest and greatest last year when i was aware of it being available.I noticed there's 2 green LEDS showing activity internally, one of which is mentioned in the 'service manual...' The duff unit is behaving the same with that in respect to the working one.Cheers

content: Yes both are on V5.01.01.07R1.I think that boot screen hang problem did go away after updating to that version, but i don't always sit there and watch it boot up if Im powering the workshop up in the mornings.So i contacted Siglent off the website and the guys in Germany responded within about 4 hrs.They sent me links to the USB thumb drive & U Disk recovery options.Its given as the latest O/S version so i didn't have to update after. It seems to of made the problem go away and it boots fully and working.What i did notice on my unit is that it would trigger once every few minutes or so even though it appeared to be completely frozen.I'll give it a good work out tomorrow and see what happens...Cheers

content: Quote from: tautech on March 08, 2023, 02:30:03 pm@tautechIf you have good contact with the engineers, write to kick the ass of the manager of these SDM series products.Don't get me wrong, because I still think it's a good product for the money and there really isn't much to refine and it would be a strong competition for other companies' products. Unfortunately, in my opinion, this is the weakest Siglent product I have, and it's also easy to improve (because it requires only a few corrections in the firmware).

content: Quote from: FordRanger1998 on August 11, 2025, 10:37:42 pmCopy/Paste should be okay but many Drag and Drop.The Root is where you see all the folders and files in a drive, where the folders are at the top of the tree and individual files below them.On a blank/empty/freshly formatted drive only the copied over files will be displayed.

content: Quote from: FordRanger1998 on August 11, 2025, 10:57:11 pmSo let's check your process....You should be fitting the USB stick to the SDM and then pressing the power button.The USB stick activity LED (if it has one) should indicate activity.Also try unplugging it before attempting recovery....Post this units SN# so I can check age and if the older FW it had from factory even supports USB recovery as we may need to take a different approach.

If the meter is out of warranty, I'm probably going to dump it. With my health issues, I can't get more wrapped around the axle with this thing. I have two working Fluke 45's. I sincerely appreciate all of the help from everyone here.

Concentrating on something too long causes me to get a bad headache, which makes understanding things very hard. It's probable I missed something.. I'm still waiting for word from Siglent..

content: Funny, before I updated to 09R2 last night, I could easily get into the meters system by pressing shift + utility, but now I can't..? I wanted to see exactly what the whole FW version is and post it. Also, I read over the upgrade threads. It talks about modifying a string in the firmware. I'm really scared about messing with that kind of stuff. I have neurologic issues including dyslexia which makes me prone to making mistakes. These issues have reduced my ability to where I only mess with small projects. Most of my equipment is now beyond my ability to use them. I'm only telling you all this so you understand my hesitation and limits. Well, after MANY attempts, I finally got into sys info. Attaching a pic of it.

I find a list of available 3055x firmware versions, the one needed is not offered. So, I'm having trouble finding this 3055x firmware update. If I'm able to download it, I have no clue how to access it and modify it. I feel like a three YO trying to figure out a super collider..
