Is there another way to bring it back to life? I've noticed microSD slot next to UART interface, what's it for?

--- Code: ---df
Filesystem           1K-blocks      Used Available Use% Mounted on
ubi0:rootfs              36696     12744     23952  35% /
mdev                     62884         0     62884   0% /dev
/ #
--- End code ---

--- End quote ---

df will list only the mounted drives.
type

--- Code: --- dmesg
--- End code ---
after you plug the usb and see witch device/partition will be listed as usb

and then try to mount the usb device again.

Thank you ratmole! We're working on a problem with tautech now. I've found that there's no power on the USB port - I believe it becomes active after the HW check, but my scope can't get there. I've checked USB power on a good 1102CML+ and it really appears simultaneously with the main user interface. So my flash drive's LED isn't lit when plugged into the scope. I think it won't be listed in a device list too, since there's no power.

We're relying on microSD card recovery now, but I've got some troubles formatting it. Gotta look for old low capacity cards at home. Anyway, thank you for priceless information and for your readiness to help a complete stranger!

And the biggest THANKS goes to tautech as he helped me to resurrect the oscilloscope! Moreover, it became 1152CML+, which is a nice bonus!

Everybody struggling with Siglents stuck on a startup screen - don't hesitate and contact tautech by persanal messages. It's truly a miracle that we couldn't find help from local equipment reseller but found it in New Zealand!

Also thank you ratmole for explaining how to use UART. It helped me a lot while finding the root of evil.
