"None of the bootloaders are running on device" when flashing the AGX Xavier

Hi!
I deploy Jetpack 4.4.1 via Sdkmanager on a XPS13 host with Ubuntu 18.04 to the Jetson AGX Xavier P2888-0001.
During the deployment one is prompted with the request to set the Xavier in recovery mode,
This works as I can see a line with " NVidia Corp." when running lsusb.

Unfortunately the deployment process later fails with the following error:

17:51:42 INFO: Flash Jetson AGX Xavier 16GB/32GB: Error: None of the bootloaders are running on device. Check the UART log.
17:51:42 INFO: Flash Jetson AGX Xavier 16GB/32GB: Failed flashing t186ref.

Full logs: SDKM_logs_JetPack_4.4.1_Linux_for_Jetson_AGX_Xavier_2020-11-09_17-50-54.zip (140.9 KB)

Unfortunately I can’t see any UART logs. The Xavier is attached to a screen which stays black all time (but worked before with the same device).
The Xavier displays nothing on the screen during flashing or rebooting.

How can I fix this? Please help!

Also removing directories as suggested in another post did not fix the issue.

UART log is shown on your host but not on screen attached to Xavier.
You can refer to below page to understand what you need to do. You can also check topics from other forum users and see how we deal with flash problem.

It seems that the issue was caused by a damaged USB cable. It worked with a replacement cable.
