well, except trying with (preferably linux) flasher running and waiting for usb connection when that icon shows, no

Also powering it up by attaching charger (plus holding that swap button) might help with keeping the usb icon on if it disconnects because of low battery

To me it looks like corrupted data (kernel, initfs, or even rootfs partition) in flash memory. This can be fixed by reflashing. How many seconds it is from first nokia logo after power on to next reboot (=next bright nokia logo) ?
