Upgrading the Hantek DSO4072C and DS4104C oscilloscopes bandwidth up to 250MHz

<< < (8/15) > >>

Hi W1ZZT3XX,

I bought a Hantek DSO4084B from ebay.de for 265,14€ it was shipped directly from China and arrived after 14 days.

Following your manual, I could change it to 250MHz, thx for that.

I read out the EEPROM, it contains following information:

1. 0x0007 "80M" (changed to 250M @0x0006)
2. 0x0027 "DSO4084B"
3. 0x0048 "Hantek"
4. 0x00C9 "DSO"
5. 0x014A "hantek"
6. 0x01CB "CNxxxxxxxxxxxxx" Serialnumber 13 numbers, which is equal to the calibration document of the scope.
7. 0x020C "163190" Language
8. 0x0216 "1" ?
9. 0x0227 "101.001.001.000.000.000.0"

Maybe somebody find it useful  :)

Hello,
 I am new to this oscilloscope and recently bought a Hantek DSO4104B.
Today, when I start it, I have the logo with all the lights on and it never starts.
I leave a photo for you to see. Can somebody help me? I think it's the damaged firmware, but I don't know how to load it.
Thank you.

The solution is simple, you need to restore the file system in scope. Try this:

Turn off the oscilloscope
Turn it on, wait about 2 seconds and turn off again.
Turn on one more time, a menu will show on the screen.
Press F2 to select the option "recover system", confirm and wait, the process takes some time.

After the restoration, update the device to its latest FW.

For more details you can check Hantek's support forum: https://www.eediscuss.com/forum.php?mod=viewthread&tid=14831&fromuid=26055

Thank you very much I just did it and it was really working. saved my life.
I have another query, now that I start, download the latest firmware from the official website, but I get an error and it doesn't let me do the update.

That I don't know, try sending an email to Hantek or posting a message in their forum, it can take some time but, eventually, you'll get a reply from their support.
