Orin with Jetpack 5.0.2 brushing failed

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 1
Command prompt:
Writing mmcblk0p11 partition done
[ 1473]: l4t_flash_from_kernel: Successfully flash the emmc
[ 1473]: l4t_flash_from_kernel: Flashing success

Reboot target
Run command: sync; nohup reboot &>/dev/null & exit on root@fe80::1%usb0

Cleaning up…

But it cannot be started; Power on and start up again to enter recovery mode; Felt that there was no mb1 or mb2 brush。

Hi 305248199,

please check below steps to backup/restore a Jetson device using the backup image

$ sudo ./tools/backup_restore/l4t_backup_restore.sh -b -c jetson-agx-orin-devkit
$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --use-backup-image --no-flash --massflash 1 jetson-agx-orin-devkit
$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 1

Yes, that’s my step. But it failed.

Hi 305248199,
during first two steps, any errors? or only l4t_initrd_flash.sh faild?

There is no problem with the first two steps; This is the third step, namely:
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 1
The command does not report an error, and prompts that the machine was successfully flushed, but the machine cannot be started, and the serial port does not output any log

Sorry for the late response, is this still an issue to support? Thanks
