Need help hacking DP832 for multicolour option.

<< < (86/91) > >>

RoGeorge:
I guess this disk image, Rigol_sign_disk.zip (62.31 kB, attached at the end of this post https://www.eevblog.com/forum/testgear/new-rigol-ds1054z-oscilloscope/msg3613778/#msg3613778 ) should be good for DP832, but I only tested it for DS1054z.

- download the "Rigol_sign_disk.zip" and unzip "card_FAT32_w_SIGN_manually_added_103E00"

- if you have a Windows PC, write the file "card_FAT32_w_SIGN_manually_added_103E00" on any USB drive you have using Win32DiskImager (do not copy/paste on the USB drive, write it using Win32DiskImager program)

- if you have a Linux PC, then dd the extracted file to any USB drive (no preformat required), for example

--- Code: ---sudo dd if=card_FAT32_w_SIGN_manually_added_103E00 of=/dev/sdx && sync
--- End code ---



The format type of the USB drive doesn't matter for this method, because either dd or Win32DiskImager will overwrite sector by sector the USB drive, and the "card_FAT32_w_SIGN_manually_added_103E00" file also contains the partition table (so the proper format).

Once the Rigol upgrade work is finished, format the USB drive again using the PC, to regain the normal functionality of the USB drive.

Hoping this isn't the wrong place to ask, as this seems to be discussion around the model change hack, but I just bought and received a secondhand DP832, and immediately updated to the latest firmware.  I then tried to apply the riglol hack (entered my serial number on the page, left the AAAA default options, and it generated a licence key.

However, when i try to install the key at the "licence" prompt, after entering all the characters, I press OK, and it says "Invalid Serial" number.  I have tried twice without success, and even tried regenerating the key on the site several times - it creates the same key every time.  Double checked that my serial number was accurate too...

Am I doing this wrong?  Or is the latest firmware different and no longer allows the licence hack to work?

UPDATE:  I got it to work.  Had to do each option separately - skipped the RS232 since I had read that one doesn't work anymore (which is fine by me, and I didn't plan to use it)...

Now on the the model upgrade! :-)

Dear spiff72, I faced the same problem as you, please tell me, when you selected each option separately, did the private key change? It doesn’t change for me, even though I choose the AAAA option, at least some kind of separate one. Firmware version 1.06.

RoGeorge:
If you do the model upgrade from DP832 to DP832A, then all the possible options will be included, so no need to add any option to the DP832 before turning it into a DP832A.

Dear RoGeorge, thank you for your comment, I have upgraded the power supply to model 832A using the described instructions. Please tell me if it is possible to roll back the firmware and return the old interface, maybe my views are old fashioned, but I really like the green font on a black background, it is bright and easy to read.

RoGeorge:
I have never tried to downgrade, but my guess is the exact same procedure you used to turn 832 into 832A should also work to change back the model from 832A to 832.  Consider doing that 7 days from now, if by then you'll still wish to downgrade.

The funny thing is that at first I wanted to revert, too, but postponed it for a few days from various unrelated reasons.  ;D

From my own memories, at first it looked like the 7 segments display was better, but in the next few days I've noticed the new font is in fact much easier to read, and having different colors for each channel made a better distinction of which is which than when they were all green.

The good news is it should be possible to go back and forth as many time as you want.
