New Hantek DSO2X1X models?

[DavidAlfa]

This issue never hapened before, maybe a defective flash? I don't know.
I suggest contact Hantek with this issue, they will likely send some platform-tools version!

[DavidAlfa]

I made some changes to dsoflash. Please download the latest version.

If running, power off the scope to reset everything.
Power the scope in FEL mode and run "dsoflash status", post the output.
Run "dsoflash erase", and "dsoflash status" again, is the output the same?.

This is my output:

The output is the same and exactly as yours, both before and after the flash erase.

[DavidAlfa]

Nothing seem wrong with the flash. Did you try restoring with dsoflash already?

Another thing you can try is to download a 132MB from here:
https://pinetools.com/random-file-generator

Flash it, then read it back, then open both files in HxD and run Analysis / Compare data to see what's wrong.

Ensure to store your original backup in a safe place, NO in the same folder, you might accidentally overwrite it.

[IonutL]

Yes, the restore with dsoflash gets me to the point where I started this conversation: the scope boots, but updates fail with the "error code is -2", some settings do not survive reboot, cannot save/ recall settings.

[IonutL]

Whoops, the dumped flash is entirely different of the read one, every byte seems to be different; example:

But the differences are too dramatic to explain why a restore of the original dump still works. Very strange!

[IonutL]

And the weirdest thing of all: I flashed back the original file I dumped from the scope when I got it, then read back the flash content, and they are identical ! Hard for me to understand what's happening...

[DavidAlfa]

Few more test: make a dump after erasing, should be all FFs...
I would start a claim with the seller right now.

There is a https://4pda.to/forum/dl/post/29004439/Hantek2D15_V17_3205.rar new version of platform-tools on the 4pda forum.
After this platform-tools:
SW 1.0.2.0.0(221028)
FW 3205

[DavidAlfa]

It's not a new version? We already had 2022.10.28_fpga_3205.
Edit: Yeah, it's the same filesystem. Same MD5 checksums.

[vistorik]

It's not a new version?

Look at the "Programm DSO2000 series Guide.pdf", no more PhoenixSuit_CN.msi installation. The Guide is new.

[DavidAlfa]

Just using the bare driver, extracted from the  Phoenix Suite. That's what I do in the unified pack.
Else than that, nothing new.

After my trusty old Atten/Siglent decided to brick itself, I just got my new DSO2D10 via Amazon AU - a bit cheaper than Aliexpress or Bangood, free shipping from AU to NZ and delivered in a week.  Out of the box, it's a pretty good scope for the money, but my motto is "If it's broke, fix it; if it ain't broke, hack it till it's even better".

So first, many thanks to the contributors to this forum for their excellent hints and advice, and to DavidAlfa in particular for his expertise and the various hacks and tweaks on google drive.

My DSO2D10 came with the latest firmware installed, but I reinstalled it anyway, along with the DSO2000 and Keysight PC apps and driver, then ran a full platform-tools backup and Backup_Builder for safety's sake.

First I upgraded it to DSO2D15, all OK except that PRIVate:READ:EEPROM still showed DSO2D10. Not sure if this causes any issues, but PRIVate:SET:MODEl1 and PRIVate:SET:MODEl2 to DSO2D15 fixed that issue.

Then I installed and tested Factory_Reset_Daemon (just in case of lockups), and installed the Small_English_Font which made the interface look a lot nicer. I also installed bmp2png_Daemon for when I want to save screenshots, and then used patcher to change the trace color for channel 1 to orange (CH1_COL="\xFF\xA5\x00") instead of yellow, to match the button color.

It would be nice if patcher also changed the ID, Trigger and channel block (at the bottom of the screen) but I can live with that.

Finally, I tested and overclocked to CPU_OC_PLL_N=28, CPU_OC_PLL_K=2, CPU_OC_PLL_M=2 and MEM_OC_PLL_N=16, which appears to be rock solid stable so far.

The only thing I haven't succeeded at so far is installing the USB Console "dso3kb_usb_console_install.upk" - it gives a message "Update Failed! Error code is -3". Not sure why this is, any help appreciated.

Anyway, it's a significant improvement on my old Atten/Siglent and I'm loving it so far - no lockups or odd behaviour (yet!)

[DavidAlfa]

You also have to modify some pictures to match the new plot colours, see here:
https://www.eevblog.com/forum/testgear/hacking-the-dso2x1x/msg3606590/#msg3606590

Check out the existing theme, for "visually impaired" as some people have trouble perceiving the difference between green and yellow.

You can extract it using the provided upk tools, all the files are inside, modify the colours, build the upk and done!

[serafis]

Thanks. Worked out how to do it from the document in your link.

[DavidAlfa]

Because you probably didn't read anything? 
They're not in some usual picture format, that's why I linked that message but you missed the "SEE HERE" part.
Download the pdf and read the section 6.2.

[serafis]

Correct. My bad    All sorted now and loving the new color scheme, orange for CH1 and blue for Wave generator & Burst, to match the button LED colors :-)

is the USB console upk installable on this model? Gives me an error code -3

[DavidAlfa]

Nice! Would you mind to share the theme package?
For sure someone else will like it.
USB console should work for all.
Error -3 ? Perhabs a corrupted package? Try downloading it again.

You're right about the patcher, I will look at the picture format, shouldn't be too hard to also patch the pictures on the fly.

[serafis]

Here's my theme attached. The font colors for Ch1 in the Measure menu are still yellow rather than orange - couldn't find a way to change that.

After installing stock firmware, I install my button_match theme and then Small_English_Font. There's probably a way of incorporating Small_English_Font into my theme but I'm only just starting to learn this stuff!

Yes, downlaoding USB console again worked thanks.

[DavidAlfa]

There were more suspicious data nearby the plot color table,.might be for other unimplemented functions...or for the measurements.
It takes an inmense amount of work to reverse-engineer the binary in Ghidra, patching it, copy to the scope, test, nope, keep trying other locations... very slow and tedious.
I did 99% of all this during the pandemic as I were 24/7 alone at home!
But cannot spend a week with coffee, nachos and loud metal anymore (Work, sleep, eat, blah blah), also I lost a lot of interest as Hantek is not fixing anything.

[serafis]

Quite understand and really appreciate all of the hard work you put into this. Still a pretty good scope for the money and for what I need it for :-)

[Aldo22]

I still don't know what to make of this device.
To some it's the biggest piece of crap ever assembled, to others it's "a pretty good scope for the money".

It's perfectly clear that it doesn't come close to Rigol and Siglent etc, but it costs less than half as much here.
So in principle it can still be good value for money if you don't have too high expectations.

Somehow this thing appeals to me. I love cheap stuff.
The basic functions should work though.

I know... 

[serafis]

It's a lot better than my old Atten/Siglent SDS1152CML which is now just an expensive and unaesthetic paperweight! At least this thing is just about impossible to brick!

Thanks!

Would you say that a DSO2C10 is worth CHF 140.- (~$156)?
Because that's how much it should cost tomorrow at the promotion, if I interpreted that correctly.

I was actually going to buy a Rigol DHO802, but I'm a little disappointed with my first impressions of this unit.
There are a few things that bother me, and "cute" and "12 bit" alone is not enough for me to pay significantly more than double the price of the Hantek.

I know a lot of people talk bad about these cheap Hanteks, but they also talk bad about the Zeeweii DSO2512G, which I haven't regretted buying for a second.
The difference is perhaps that the Zeeweii never crashes.

[serafis]

I'd say that's a pretty good price if you don't need the wave generator. It's certainly not the best scope in the world but it's not the worst either. really depends what you need it for - most of my work is on audio (analog and digital) so adequate for that, although an old CRT analogue scope also comes in handy for CD eye patterns and the like.
