I had mine bricked and was able to bring it back with a reflash so should be no worries. The only thing we may have to do is try and install the versions in order of there release but i dont see that being a problem just jumping to the most recent. When you start it up holding the down on the key pad it should go into boot loader screen what number is on that screen should be 3.26d ?

I did the test and saw the the firmware is given as 3.22A !

Which I guess explains something?

Where are the instructions for uploading the firmware, please?

Thanks for all this help!
Ciao,
Bob

Well I did the upgrade, and now all I get is the black screen with the labels, no trace display and no controls work!

It's dead...

Where can I get the older firmware, please?

Try them in the order i posted them starting with 4 then 411 and finally 420 only install one at a time then try it and if it dont work on to the next im going to add one last file try this one first acually its the ben f for the 3.22 boot loader it will be the best for functionality if it will take if not then try the factory ones. The files with 2 files need to both be installed one after another and make sure the file changes to the dry extension. Dont stress its will be solved :-)

Hi!

You are the MAN!!!

The BenF firmware seems to work! The trace is stable, and the buttons all work.

I'll try some measurement later and let you know!

It's been quite a struggle, but it's starting to feel worth it :-)

Thanks so much!
Ciao,
Bob

On the benf there are 2 files app and lib did you get them both on and you have to do both one at a time some have had problems trying to highlight both at the same time

I am running linux on my pc and am an IT expert ;-)

I put the Benf files onto the Nano one at a time and it worked immediately, or at least the buttons work anyway.

The BenF seems to work fine on the Nano V3, but still no measurement test for lack of time. The interface looks a lot cleaner and the trace is sharper.

I'll let you know any results!

Thanks again!
Ciao,
Bob

I've had the DSO Nano for a few weeks now and am a little disappointed with it. I've had the same problems described in this post. I tried the firmware upgrade to 411 and 420, of which neither functioned (unit initializes and screen shows a static image with menu on the right-hand side but no buttons work and no trace drawn). The BenF firmware doesn't even show anything on the screen. When I power on my unit it shows DS201+ APP Ver4.00. When powering on while holding down it shows: Device Firmware Upgrade V3.22A.

Can anyone help me with this one???

Thanks in advance!

Hi!

I am no expert, but I managed to follow the firmware upgrade instructions and can now use the BenF firmware given in the post of Sat Jul 13, 2013 4:13 pm in this thread.

Please try that and let us know.

ps. I did all my upgrading from a Linux Ubuntu pc, maybe that has some advantage?

Cheers,
Bob
