I find this thread absolutely amazing and awful in the same time.
I spent few hours several of days reading through the pages.
It is an amazing job, knowledge, interactivity and solutions found.
It is awful for a new comer which would like to follow and understand the proposed solutions.
I have read so many times the same words similar with “read few pages back”, “somewhere in thread if you read it through”. It is totally unorganized from my point of view. It is awful.
I can understand that is related with how the solutions evolved based on tests, experiments, trails, communications, but once a solution is found, it should stay somewhere easy to be found by a new reader.
I have seen new comers on the topic asking the same questions and sometimes a good willing older user copied and pasted the solution, because the new user is lost in the forest of trials. After the solution was found, some other guys still had all kind of problems and others not. Then all these important info spread along many pages is a headache. It is like half of job done.
Why is it like that? Is it on purpose? Or is no one able to organize and publish the solution as top line, a header, a new thread, a link with simply steps organized? It would be helpful at least to understand why. In the end are not so many versions of the firmware. The version 2.35 is an important step and then comes later 2.41. Then is USB method for old and LAN card for new. USB requires downgrade for versions above 2.35 to the version 2.35. Then are all kind of tricks and mistakes done by different users. It is a headache.
I was thinking once reading through the pages, why is it so unorganized after the solutions were found and can someone tell if it is true at least the ideas below that came into my mind?
It is spread and unorganized, because:
- No one care to do it organized.
- It is easy to hide the solution/hack for the other search engines or other technical people outside the forum (from Agilent?), because they must spend also hours and go through so many pages to understand what solutions have been found here.
- After so many hours of trails and tests, the experienced users who found the solutions, decided that at least this is what other new readers can do when receive the solution for free without their own brain work: to read the pages back and find the solutions spread along the xx pages. That would be fine, but still is a big headache because is spread and twisted along so many pages. If it is meant to be free for others, then to whom does it help to not be organized?
Reading the pages back to find the solution produces only frustration until you find and understand the procedure.
I have a Rigol DS4034, for which was far easy to read and follow the unlocking procedure. For that I am thankful to the guys that did it and share it. My Rigol has all the functions unlocked.

If I will do it, then I will make a step by step tutorial, if it is necessary with screenshots and video recording, so any new reader will able to follow it in less than 15min, without reading xx pages back.
I have the firmware version 2.36.
https://goo.gl/yvf7Of If I understood right I have 2 options: I downgrade to 2.35 and I use the USB stick trick, with the proper USB drive – here trials are waiting for me, or the hack with LAN card and telnet software/commands.
After so much reading I still have some basic questions:
- What do I lose if I downgrade to 2.35 from 2.36 or any other firmware higher than 2.35? I mean besides the advantage of being able to unlock the oscilloscope when I have the firmware 2.35, what do I miss? What advantages offers 2.36 or 2.37 or the latest 2.41? Is it really important to have the latest 2.41 unlocked? Or are the people happy with downgrade to 2.35 and being unlocked with all the features?
- Agilent offers LAN/VGA card at over 400€. Is that card that is needed? Or do I need a special hand-made one? If I need a special made one, who is selling it here on forum and at around what price?
