Alright, my fellow EEVBloggers!
I would be happy to post the new hacked firmware that downgrades every FW revision up to v2.06 SP0 included, down to v2.02 SP2 along with the original FW v2.06 SP0 (2.06.00.01).
But, given that all the "illegal" firmware attachments were removed from this blog at some point, makes obvious that posting the FW files above puts the blog at risk.
Let's review some facts:

I still haven't heard of anyone downgrading the 2.06 firmware. As far as I know, no-one has even posted a copy of the 2.06 firmware anywhere yet.
Well, I have done it, Richard! And reverted back to v2.04 SP1.
Drieg led the way, providing us with some valuable information:

...don't waste your time, seems that Rigol made a stupid mistake and forgot to prevent a FW "upgrade" to the same version
Besides that, I didn't notice any difference between v2.5 and v2.6, at least the menu is very same.
The fact that v2.06 can "upgrade" itself is the key!

A. Hellene cracked the header code in this post:
http://www.eevblog.com/forum/index.php?top...g42404#msg42404Theoretically, the same approach can be used to modify the 2.06 header
Exactly, Torch! The method remains the same.
Recently, I posted the header of FW v2.06 SP0 (2.06.00.01) along with other ones at this message:
Code: [Select]
---------------------------------------------------------------------------
HEX Address: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14
---------------------------------------------------------------------------

The steps to take are the following:
1. Find the original v2.02 SP2 (v2.02.02.00).
Original v2.02 SP2 file CRC32 checksum: A3370F0E
Original v2.02 SP2 file MD5 hash: 272086B2037231C62446617436544A77
2. Open it with a hex editor and replace the first 21 bytes of the header with the 21 bytes of the v2.06 SP0 (2.06.00.01) header, posted above.
3. Save the new file, which is recognised by the DS1000E as v2.06 (2.06.00.01) but it actually is v2.02 SP2 (2.02.02.00) and can change the model and the serial number of the device.
Hacked v2.02 SP2 file CRC32 checksum: 0C83CBD6
Hacked v2.02 SP2 file MD5 hash: 19EB82AB1FA4FE57CC9410F2074E9E67
Note that changing only the model will not work after a reboot. In order to save the model permanently it will also be needed to re-enter the serial number. Enter the serial number the device will return after the ":INFO:SERIAL?" command, or as it is displayed in the sticker at the back of the device; there is no need to change the model letter (D/B/F) within.
4. Change your device's model & serial number and upgrade your firmware to v2.04 SP1 (2.04.01.02), or higher, immediately!
DO NOT operate any further the HW58 devices with the hacked firmware or with any other firmware of a revision lower to v2.04 SP1.
Try also to avoid all the v2.05 revisions that introduced flickering or other bugs.
5. Done! Enjoy your crime!
P.S. The files mentioned above can be found online. So, please, do not start asking me to be sending or emailing them individually...
