DSC4102C firmware update problem (error 0xfe)

pgiorgio61

I uploaded the file 20200722181235_227151402.rar on a USP 16G and on a 1G but the effect is the same. The message I receive is error 0xfe - No upgrade files detected on USB device!
I have a DSO4102C brand new with sw version 3.50.0 (200410.0).
Please help...

I’ve tried but the 4102 doesn’t recognize the SD. It’s looking for a USB stick.
I managed to unzip the file and I put back on a  2G USB formatted FAT32 but no luck.
Any other suggestions?
Many thanks.

Thanks for your suggestion but, unfortunately, doesn't work.
This is what I have done:

1 - formatted an USB 1G in FAT32
2 - downloaded the file 20200722181235_227151402.rar
3 - extracted the file dso4kc_func_hantek_dso_dso4102c_20200722.0.up
4 - copied the file in the USB (it is the only file present, no folders or other files)
5 - insert the USB on the Oscilloscope DSCO4201C and follow the instruction (up to F5)
6 - got the message "Firmware update failed, error: 0xfe - No upgrade files detected on USB device!"
7 - The System Information are:
     [model] DSO4102C
     [sw version] 3.50.0 (200410.0)
     [hw version] 1020xffffa022
     [serial number] T 1G/049 010816
     [boot count] 6
     [upgrade count] 0
     [lcd.front.ts] 3.0.0

Anything else I can try?
Many thanks.
