FW update, verification fails

[LILO]

Hello.

Unit purchased ready-built from UpTech long ago and worked well. Now I try to update FW via USB. Flashing stage goes well but right after it device reboots immediately. So, verification stage fails with timeouts.

Any suggestions what could be the cause? Nevertheless, the unit seems to be fully operational, new FW is in place.

Thanks

SOLVED

Another USB cable did the trick.
But got some new troubles, but that is another story.
