Hello,
At first I would like to say hi to everyone, I am completely new to this forum (although I have been watching Dave videos for years)
I would like to ask for help in repairing the VOLTCRAFT DSO-1084E oscilloscope (Hantek DSO4084B). I bought it for a penny (already damaged) hoping that I would be able to do something with it. Unfortunately, I got stuck
I checked other threads on the forum and I found nothing similar to this.
Oscilosope is stuck on Logo/Boot screean or after "hard reset" in recovery screan with information "System is not shut down properly..."
Logs from "normal" startup:
system reboot

I am able to execute linux commands only after starting in recovery mode.
I found most directories are just empty, for example
/dso:
[root@Hantek ~]#ls -la /dso

Then I noticed that it is impossible to mount the pendrive (FAT32), I only get the message:
mount: mounting /dev/sda1 on /mnt/usb failed: Invalid argument
This led me to a clue, so I started checking what's in the
/mnt directory. And it looks like almost everything is empty or not mounted (?)

After that, I also tried to insert the microSD card and see what will happen (currently I don't even know how to copy something to the oscilloscope). The oscilloscope would freeze then endlessly attempting to mount the card:
VFS: Mounted root (ubifs filesystem) on device 0:10.

Analyzing it, I came to the conclusion that it might be possible to restore the oscilloscope from backup, but unfortunately there is no backup:
sh ./recover.sh recover 3
gpg: fatal: can't create directory `root/.gnupg': No such file or directory
secmem usage: 32/32 bytes in 1/1 blocks of pool 32/32768
tar: can't open '/tmp/update/recover.tar.gz': No such file or directory
tar: can't open '/tmp/update/recover*.tar': No such file or directory
chmod: /tmp/update/tekwayup_client/update.sh: No such file or directory
./recover.sh: line 156: /tmp/update/tekwayup_client/update.sh: not found
Maybe someone with a similar oscilloscope is able to provide it to me? Although I do not know yet how to copy this backup there
Thanks in advance for your help and time
