New Hantek DSO2X1X models?

IonutL:
And I have uploaded on Gdrive the files (in the writable folder).
Thanks again.

After you flashed the scope using platform-tools, the calibration generator file dds_calbration.dat could be restored by the system using calibration coefficients from EEPROM PT24C02. You could check this using dso3kb_CNxxx_Calibratio.tar.bz2 and dso3kb_CNxxx_EE.tar.bz2 archives from your backup. From the dso3kb_CNxxx_EE.tar.bz2 you could get ee.bin - this is the dump of PT24C02, and from the dso3kb_CNxxx_Calibratio.tar.bz2 you could get dds_calbration.dat. Using any HEX-editor you could see calibration coefficients in these files in Hex and Double float format. To convert these formats you can use a Floating Point to Hex Converter (https://gregstoll.com/~gregstoll/floattohex/). /). Calibration coefficients in HEX format (HEX value) must be entered byte by byte in reverse order, and then you click "Convert to double" - these should be calibration coefficients in ee.bin (see the pictures as example). The calibration coefficients in the dds_calbration.dat and the ee.bin are in red frames.

I've been reading this thread for 3 days now, and I can't thank everyone enough for sharing their knowledge and experiences.  Very much appreciated. 
I just got a Hantek DSO2D15 off Amazon for $215USD, and so far, it's been great except for one thing:  I work with MIDI, so I need to decode UART at custom baud rate of 31250.  So far I haven't been able to get there because:

* The initial value is ~115200, and the multifunction knob only increments/decrements by 1.  You can imagine how long that takes to get to 31250.  Still, I tried.
* Once I got down around 49000, the number would randomly increment by ~10000, ~1000, or ~100, with no discernible logic to which one.  If Hantek tried to implement ballistics on the multifunction encoder for custom baud rate, it needs work.  Or I'm doing it wrong.
* The error always increments the value, never decrements.
* At this point, I can never get below 55000, because once I get down around there, no matter how slowly I roll the multifunction encoder, the value will always jump up by one of the aforementioned amounts.
Has anyone else seen this? 
I would assume a workaround is to set it manually via PC connection, but it seems odd that Hantek didn't implement the custom baud rate by allowing you to choose a starting point and rolling from there.  But like I said, I may be doing it wrong.  The manual is fairly sparse on this subject. 

I'm also on a Mac, so I haven't tried to set up the SCPI tools yet. The eediscuss forum shows SCPI commands available for the Trigger/UART namespace, so maybe I can set it there?

Software is 1.0.3.0.0(230831.00)
Hardware rev is 003.002.000.000.000.000.001
Firmware is 3205.

DavidAlfa:
Rotate slower, then it'll let you adjust it. If you go too fast then yeah, it'll go in 1000, 10000 steps. (Or maybe it's a new software bug introduced in the newer version you have!)
Unpack this setup file, copy the .pho file to the root of a usb drive and load it from the Save/Recall menu (Choose external)

23.08.31 is a newer software version, not released yet!
Please run Backup Builder and send me the FULL package so I can make a new update, everything is in the FAQ (Check my signature).

Edit:
For whatever reason, I mean, because it's *** Hantek, it saved a crooked setup, the scope went extremely slow after loading it.
Saved a new setup, this worked as it should.

DavidAlfa, Full backup uploaded to your drive per the FAQ and the Hacking thread.   Your .pho file gave me the 31250 baud rate I needed, cheers!
