 Hello , I hope everyone is doing great.
I am having problems with my SDS1102CML+ DSO, Its Stuck at BOOT logo, I tried doing factory recovey but it isnt working, Below is my Serial Log.

Don't need logs.
Send me PM.

[Roman555]

@tautech ,
do you still help owners of digital oscilloscopes Siglent ? Please, help me too.
I also have Siglent SDS1102cml+ (for my hobby) and it doesn't boot anymore.
The story is similar : it was turned off the day before and it didn't boot the next day.
It just stuck on boot logo. I tried to press MATH rapidly and although the device did reset but there were no changes.
Is there a way to restore my digital oscilloscope not opening the case?
Though the warranty is off a long ago...
Thanks!

Upd.
tautech is helping me. Many thanks him.
The oscilloscope appears to be picky about a recovery method (the USB recovery doesn't work because of too old firmware).

Upd2.
My oscilloscope is recovered successfully. Now it also has a fresh firmware 
I thank tautech for his help and resources, and also this forum that connects people living all over the world.

Hello!
I have an oscilloscope:

Yesterday it stopped working.  This always displays the boot logo.  I tried resetting with the Math button, but that didn't help.  I want to try flashing it.  Help identify the original model.  I know for sure that this is a plus model, it has an ethernet port.
Sorry for my English

Hello good night. I have a problem with an oscilloscope siglent SDS 1052DL+. This is in logo stuck, it can start.
Thank you for your help. Best Regards.

Hello good night. I have a problem with an oscilloscope siglent SDS 1052DL+. This is in logo stuck, ........

Welcome to the forum.

Close it up and we don't need a dump to fix it.
Send your email address by PM and we will work with you to recover it with our USB tools from Siglent.

Hi everybody. My SDS1102CML+ turned into a brick after trying to update the firmware "SDS1000CML+ Firmware_V6.01.01.22 (Release Date 08.06.21)". At the moment, after switching on, only the Siglent logo is displayed on the screen. The oscilloscope startup stops at the Linux kernel starting stage. @tautech can you help resurrect my oscilloscope?

Hi,

I have the same problem.  The SDS1102CML+, it has the initial screen stuck. I bought it a few months ago to do my hobbies but now I turn it on and it gets stuck on the home screen. Need help and tools like you said. Thank you

UPDATE: All is ok now! Thank you so much, tautech.

Hello,
I use this post to ask for help, I have exact same problem with my SDS1102CML+. It is stucked on the "Uncompressing Linux... done, booting the kernel." message.
Can I ask you for help in private messages too tautech ?

Hi,
My SDS1102CML+ prints "Uncompressing Linux... done, booting the kernel." and nothing more.
I tried to flash files from P21R2.zip, which was posted in https://www.eevblog.com/forum/testgear/siglent-ads-firmware-file-format/msg3280472/#msg3280472 but that made no difference.
I noticed that files P21R2.zip are from 2015/2016 but my SDS1102CML+ is new.
I wonder whether I can download some other, may be newer files from somewhere?
Thank you

Welcome to the forum.

All recent firmware files are here at the US Siglent website:
https://siglentna.com/service-and-support/firmware-software/digital-oscilloscopes/#sds1000cml-series

[jhnlmn]

But official firmware from Siglent only contains P21R2.ADS, which cannot be installed if Linux does not start. Can it?
I tried placing P21R2.ADS to USB stick and rebooting, but nothing happens.
I see that it is trying to read ro_uImage, rootfs.img, datafs.img and logo.bmp, but not P21R2.ADS.

Hello everyone! I have Siglent SDS 1102CML+ at work that doesn't start.

Is there another way to bring it back to life? I've noticed microSD slot next to UART interface, what's it for?

Contact me by PM with your email.
I have some tools that will help...........

Googmorning tautech,
my name is Francesco and i m a newbie. Last week my friend gifted to me a sds 1102cml+ with a lock logo screen ...and ..if possible, i would fix it.
I have many problems....because my english is so bad and my skill in this topic are too low for understand all...but i know somthing welding  electronics boards
So...I soldering wire and connect to rs232 usb adpator. I download from siglent Easy scopex and i conneced to him with rs232 ( same photo on link  [url]https://www.eevblog.com/forum/testgear/help-restore-sds1000cml-after-unsuccessful-flashing/25/]https://www.eevblog.com/forum/testgear/help-restore-sds1000cml-after-unsuccessful-flashing/25/).
Now i don't say how walkaway....
Thank a lot
Francesco

I would like to add a "me too" posting in this thread. I think I have a similar but different issue?

I recall I attempted to flash the firmware on my SDS1102CML+ and it never came back up.

I've done the USB recovery with P21R2.7z but I still get an error about /dev/ttyO0 not being found.

Does this look like a bad board or a bad kernel/firmware?

Thanks.

Is the scope working or not?

tautech got me up and running with proper recovery files. just working out the last few items, but it's back up and running.

Yup.

Note to all, please don't go opening your scopes to sniff any data bus .....it's just not required !

Hi. 

I’m also new to the forum, however long time viewer of Dave’s YouTube channels. I’m only a bit of a hobbyist & recently when I tried to use my Jaycar QC1934 oscilloscope I have also fallen victim to the “Stuck on Splash Screen” issue that has been discussed in this forum. I have never updated the firmware and seemed to work fine for the last 3 or 4 years.

I believe it is actually the siglent sds1102 cml plus, correct me if I’m wrong Ref attached photos. No relays click just splash screen, Repeatedly pressing math button doesn’t do anything. Just all buttons lit up and a led inside pulsing. It has a sd card slot, lan port, usb, bnc connector & an unpopulated J11 pads.

I have tried to contacting siglent for support, the American address info@siglent.com keeps bouncing back, no reply from the other 2 email addresses.

Any help would be greatly appreciated. TIA
