I need to restore the firmware. I can access UART if needed.

Hello friends.
I was able to restore the functionality of my DSO1152S by analyzing the composition of the decrypted firmware archive 170801.
In short, then:
1) I recorded the decrypted and unpacked archive on a USB flash drive.
2) at the end of the failed download, the oscillator closed the operation of the watchdog timer by issuing the killall dsod command
3) created the /tmp folder in the root and copied all the files of the unpacked archive there
4) launched the update script file from the root do_update.sh in the copied archive folder
5) Restarted the oscilloscope.
Voila, everything works!

If you are interested, below is a complete, directed uart log of a single session, including both erroneous commands and correct ones with the results of their processing:
