If you really think your Hantek DSO is "unfit for purposes as a scope" you should just return it and ask for a refund. In my case it has been working flawlessly since I received it a few months ago. I am still on the march 2020 firmware update.
And as I have explained above, it's possible to hack it without even opening the case.
Hantek will certainly release further firmware updates, but I am not sure they will satisfy your expectations/needs. Perhaps you could try another DSO from another brand and tell us how that goes?
Andrew well i guess you are the lucky one if your runs flawlessly, why are you on this thread?
My one was failing out of the box on day one, i waited few days for reply from hantek support and they provided the 20210510 fix.
Since then i have gone deeper into the scopes features and functions and it is full of lockup bugs, i am again waiting for reply from hantek.
While waiting for hantek and chatting on this forum my opportunity for returning timewise is just about past given you have 30 days for the seller to receive it in CHINA.
They say don't send it express as gets stuck in China customs, so send it snail mail and you miss the 30 day window.
Either which way I am out of pocket as i will never get the busted scope returned to me and they never issue a refund.
This is a catch 22 situation for me, i have not overclocked or messed with the scope in anyway other other than do the less than perfect upgrade.
So now i have choices ebay it and risk getting it sent back to me as faulty! Or live with then bugs that other on this thread have experienced.
Maybe a third options would be to send it back to Hantek hoping they will even bother to collect it from customs.
Await for them fix it then charge me $50 to send it back and get a VAT import hit here.
Or cut my losses and use it as a toilet brush.
And yes i have already specked out something else i wish to buy and am this time even more carefully checking out it quality.
Maybe best option of all is just carry on with my old Tektronix 2236 + Opt 14, sell duff hantek on ebay spares or repair and lose £150
Either which way i'll continue to publish the issues of this scope on youtube as Hantek need to know in times that producing Land Fill is simply unactable!
I hope your DSO2xxx works flawlessly for you for the rest of your very long life.
