S5248F-ON stuck on grub

Hi,

After a firmware update, the switch is no longer able to boot.

10.4.3.6 -> 10.5.2.2

On boot, it stuck on grub rescure and it is not able to load ONIE Boot Menu or OS10.

I'm able to access to DIAG-OS, is possible to repair grub/ONIE/OS from external USB ?

Thanks

Hi,

I would recommend calling phone support, it should be possible to reflash ONIE and the OS from the diag OS loading the files through USB, but not all of the commands are public so I can’t post them here.

Yeah! I was able to recover it.

Thanks to Dell that helped me to flash ONIE again on the switch via USB live.
