v4.001

Hi guys, I somehow managed to brick two NVRs NVR5216-16P-4KS2 with the new firmware V4.001.0000000.1 Build:2020-03-19. It is constantly losing ping and looping, (NVR 4.0 logo comes for a few seconds and restarts again) Can anyone help me or maybe someone had same issue like me? Thanks a lot...
