Hi!
Thanks for the quick response..

Done it...thank you very much...

It performed easily only following the procedure
Tv84 explains only via linux...
I used raspi....love raspi...

Best regards...

Thank so much...

For the linux people that are scared of command line:

1. What the hell are you doing with linux?

2. Use 'gparted' for formatting. Not 'disks'. That utility is a useless-tility.

3. Format the disk 'FAT32' for a firmware image, Format it as 'FAT16' if you want to make a magic disk.

This worked without fail for me.

Hi,
Can you please help where to find the custom firmware 1.08 so i can downgrade my DG811 Fw 1.09.00.02 to modify it to DG992 using TV84 method.
Thanks in advance

Hi guys,

I bought my DG811 some time ago and received it with the FW1.09. Now I would like to upgrade it and need your help to downgrade the FW to 1.08 or to test other ways of updrading for you.

Thanks for your help

Finally, got DG811 unit from China. Unfortunately, it have 2.02 firmware installed.

Is it possible to upgrade to 992?

It is, but you need to downgrade the firmware and do the unlock trick from this post: https://www.eevblog.com/forum/testgear/new-rigol-16-bit-function-generators-dg800900-series/msg2420391/#msg2420391
Unfortunately the device does not let you downgrade the firmware, so you need to bypass the version validation for the downgrade to succeed.

tv84 seems to have a working "downgrade" firmware, although he did not put it up for public download.
Probably due to the attachment-size limit, I am sure he will share a download link when he has time.

I am currently trying to take a stab at it myself, although my experience with such stuff is about zero

Rigol pulled the old (hackable) firmware from most of their websites, but by checking some of their file servers I finally found it.
If someone needs the old firmware - just ping me. Cannot upload it here due to attachment size restrictions of the forum.
PLEASE NOTE: you cannot downgrade your device with the original firmware - you need to patch it first, somehow

Is there a change log for software versions for the DG800 series at all?

thetechnick · « **Reply #407 on:** April 07, 2020, 07:31:33 pm »

If you download the latest firmware you will find a Release Notes file.
As v00.01.09.00.00 was never released as an updated, just preinstalled on some devices, there seems to be no change log entry for it.

Code: [Select]

[Model Supported] DG811,DG821,DG831,DG812,DG822,DG832,DG952,DG972,DG992,DG2052,DG2072,DG2102
[Latest Revision Date] 2020-02-18


[Updated Contents]

v00.02.04.00.00	2020-02-18

     - Add open source declaration in help UI
	 - Solve the problem of address error in ultralab heartbeat server configuration
	 - Solve the bug that the relay output instantaneous voltage error after setting offset

Fantastic thanks. That actually answers the question I was going to ask about the instantaneous output voltage as well

Looks like I'm going to upgrade my cracked DG822 to latest firmware. Will lose 100MHz but not that fussed about it at the moment.

If you cracked it "properly" the update should not reset the model designation, see:

( I already read through this whole thread way too many times... )
Just people that receive new units with v00.02.xx need to downgrade... in order to upgrade - sounds stupid, but seems to work

Ruediger · « **Reply #410 on:** April 09, 2020, 05:34:38 am »

Thanks for the answers.

I'll wait for TV84 to answer.
If any of you have an idea to upgrade directly from FW1.09 I can try it for you.

I volunteer.

Have a nice day

When I am not mistaken, AshDash was the first one with a shipped 1.09, who had to invest time and brain to contribute decisive steps to tv84 and other friendly helpers to search for a new/other way to downgrade; probably this is also the case for an upgrade to 2.04 and any further...

Let's call him a helpful volunteer and that's why he deserved a special treatment... His upgrade method is not "public".

So, from all the posts in these last 2 pages i seem to conclude that the (factory released) v2.04 equipments don't migrate the model ID from the v1.08 version because they already have a valid DG81x ID in the new memory struct area.

If that's so, it should be possible to patch the FW to do it or ... using the MODF command (which is Rigol's official way).

Edit: Therefore the "downgrade" method only works with re-upgrade up to v2.02 , as such its validity has expired.

FW 2.04 seems to have many changes to the previous.

I wondering how to patch this 1.08 script to downgrade my 2.02 unit. I get "ERROR: bad script!" message when trying to flash 1.08 FW.

Also, fw4linux.sh seems to be encoded using some other key.

So that you can better enjoy the quarantine period:

BCD2FCFECB9AB54B12D2D4AFCAFD6E0D

BTW, IVs must be 0.

evgbog · « **Reply #414 on:** April 11, 2020, 01:20:46 pm »

Wow!

I've modified (commented with #) version check section of fw4uboot.sh, encoded it with open-ssl, updated SardineUpdate.GEL (haven't updated any headers) and reflashed with "Help" key at startup, and voila:

My DG811 ver 2.02 unit transformed to DG992 ver 1.08.01 without sending any SCPI commands. Serial number changed to DG8000000000001.

So, what is my next step? Do I need send change model command with magic USB to flash next FWs?

First you must use IV = 0 or behavior can be strange...

Sure it did, that's normal behavior when you downgrade. Now you should correct the S/N and force model. Then re-upgrade. When you do that it should rollback to DG811...

Oh, that's right, thanks. I guessed why firts string of decoded block is corrupted. I fixed previous post, need to use -iv "0" argument.

UPDATE: successfully flashed to 2.02, but fail on 2.04 (model reset to 811). So, will stay on 2.02 FW.

I was asked how to prepare custom firmware for downgrade firmware version.

Here is my mini how-to guide:

1. Get 1.08.01 official firmware (available at web.archive.org of rigolna.com website)
2. Use hex editor (HxD, for example), open SardineUpdate.GEL
3. You will see encrypted block of data at the begining, starting at 200h offset. Select this block and do "save selection" to file fw4uboot.sh.aes (size 4016 bytes).
4. Decode file using command (under linux)

Code: [Select]

openssl aes-128-cbc -in fw4uboot.sh.aes -out fw4uboot.sh -d -K "BAD8CFFEBBAAB5C4C3D8D4BFCAFDBEDD" -iv "0" -nopad5. Edit decoded fw4uboot.sh. Comment ..if checkVer ...else ... fi rows like this (insert # characters):

Code: [Select]

#if checkVer "00.01.00.11.01"; then \
echo New version; \
#else \
#  echo New version; \
#  showMessage 'Upgrading failed, not new version!' 7 14;\
#fi;

6. Make sure total length of edited fw4uboot.sh is still 4016 bytes (if not, add or delete some characters in commented rows).
7. Encrypt edited fw4uboot.sh using command:

Code: [Select]

openssl aes-128-cbc -in fw4uboot.sh -out fw4uboot_new.sh.aes -K "BAD8CFFEBBAAB5C4C3D8D4BFCAFDBEDD" -iv "0" -nopad9. Using hex editor, update data block at 200h of SardineUpdate.GEL with encrypted fw4uboot_new.sh.aes
10.All done. Proceed flashing SardineUpdate.GEL to device (using "Help" key at boot method).

Next step is to use @tv84 guide. https://www.eevblog.com/forum/testgear/new-rigol-16-bit-function-generators-dg800900-series/msg2420391/#msg2420391

1. DG952 shipped with FW 01.09

2. downgrade to 01.08 following evgbog's guide, success

3. system info showing model 'DG992', SN lost

4. write model 'DG992', write original SN(DG9A2xxxx) by SCPI command, success

5. system info showing model 'DG992' with correct SN(DG9A2xxxx)

6. upgrade to 02.04, success

7. system info showing model 'DG811', with correct original SN(DG9A2xxxx)

8. downgrade to 01.08 following evgbog's guide, success

9. system info showing model 'DG992', with correct original SN(DG9A2xxxx)

10. upgrade to 02.04, success

11. system info showing model 'DG811', with correct original SN(DG9A2xxxx)

What's wrong?

thetechnick · « **Reply #421 on:** April 18, 2020, 06:28:33 pm »

What I have cached so far:

Devices that where delivered with v00.01.08.xx can be hacked and afterwards upgraded all the way to v00.02.04.xx.

Devices delivered with v00.01.09 and up can only be upgraded to v00.02.02.xx. If you upgrade those devices to v00.02.04.xx, the hack stops working.

---

Do we know if there is any difference between v00.02.02 and v00.02.04, except for the rewritten boot-scripts (that kills the hack)?
Looks like v00.02.02 was the feature/bugfix release, while v00.02.04 is just just closing the hack for now.

Hello
I have dg811 delivered with firmware 01.09,
with evgbog guide (THANKS evgbog :-)) I have downgrade to 01.08 fw, hack to DG992 and rewrite SN to original state
now in rigol website I find 02.04 firmware but i want to upgrade to 02.02 firmware, where can I find it?

thanks a lot

stupiid · « **Reply #423 on:** April 20, 2020, 03:53:43 am »
