- dso5kp_backuptool2.up
- dumpbad.txt (empty file)
- oob.txt (empty file)
The saved files will be in the "dump" directory.
The operation takes a few minutes.

Thanks a lot!
Without these two text files, I was able to backup only 4 small files, as already mentioned above.
And now 132 MB are saved!

Спасибо огромное!
Без этих двух текстовых файлов у меня получалось сделать бекап лишь 4-х небольших файлов, как выше уже писали.
А теперь сохранилось 132 Мб!

Hello friends !
I have a Hantek oscilloscope DSO5202B , I downloaded the latest firmware from the official Hantek website and I failed to update.
Please help me with the latest software version for my hardware.
Thank you.

DC1MC:
OK, let's go quickly over the procedure:

1) you downloaded and extracted the firmware a file, like:
dso5kb_func_dso5202b20190830.up

2) you have found the most miserable, obsolete USB stick, 2GB ideally, (4GB works, for me nothing over 8GB ever worked) and formatted FAT32 and nothing else, no NTFS, no exFAT and such, keep in mind the current version of windoze do not offer FAT32 anymore, they need to be specially convinced, check for yours how do format FAT32.

3) you have copied the extracted firmware file. and NOTHING else on the POS stick freshly formatted.

4) you've repeated the fw update procedure and either works or look back on 1-3 to see what have you done wrong  ^-^.


 Cheers,
 DC1MC

Thank you for answer.
I did exactly as you said.
After your post, I tried with other USB sticks, the result is the same.
Firmware failed.

Oscilloscope model in the photo.
Before creating a backup, it is updated with the latest firmware at the moment.
Bandwidth expansion is yet to come.
Now I'm working on a very high slew rate edge generator based on a tunnel diode and a transistor...

Модель осциллографа на фото.
Перед созданием бекапа он обновлен самой последней на данный момент прошивкой.
Расширение полосы пропускания еще предстоит.
Сейчас работаю над генератором фронта с очень большой скоростью нарастания, на основе туннельного диода и транзистора...
