Hello to all , my first post:

I want to say many  thanks to zombie28 and cybernet for their great work
at custom FW and keygen!!!
All goes fine after flashing and type in the key (DSHH).

I still have one question:
 - must I recal both channel with the buid in autocal functin?
 - is it recommended to put an 50 Ohm resistorload to the input-bnc?

I make some try and I done dump of my dp832 I see nand flash + spi flash +24c16 eeprom
I can't find serial number anywhere,24c16 seem to contain some calibration data, spi flash W25X40 some data like encrypted I think is here serial,and in nand flash I see more or less only first 3-4mb filled and seem like the DP800Update.GEL file something interesting found multiple refers to all model of dp800 series so I think changing serial will hack 832 into 832a since all the board same and are marked 832a I post some pictures

Will you share your memory dumps with us? If so, what firmware version do you have? I'm analyzing 1.08 GEL atm to find out the new license codes format.

My DS2D1547 serial number DS2072A scope when it was a 2072A from the factory showed hardware as 2.0... After using your old keygen mod with new firmware, it still shows my serial number correctly *and* the Hardware version still shows 2.0.

I'm pretty sure zombie28 is correct. "2.0" is just what you see when you press Utility -> System -> System Info, but it's not the full hardware version number: 1.0.2.0.2 is the actual number. If not, what exactly do you see when you look at the Extended Info (not Standard)? If you don't know how to see it, instructions are here (you will see your full software and FPGA versions as well).

Thanks for that... I stand corrected...

originally I thought he was saying that v2 hardware wasn't shown anywhere.  Indeed is it in the *regular* system info menu output.

However after doing as you suggested, I now see the other info.

software 00.02.01.00.03
hardware 1.0.2.0.2
FPGA
    SPU 03.01.09
    WPU 00.07.01
    CCU 12.29.00
    MCU 02.13

Thanks for clarifying and sorry for the confusion.

Hello,

I am new to the forum. Since I have received my DS2202A I am willing to break the waranty seal and contribute by providing the memory dumps using a FT2232 based JTAG.
From the posts begging from page 164 I understood that "tirulerbach" is the man to send the memory dump.

My scope still have a few hours left to test all the nice trigger and decode features.

Question to the experts: Does the fact that the trial is still active will influence the memory dump?

Thanks and cheers,
Pillex
