Hi patkar.cmeri,

Are you using the devkit or custom board?

You could not do the full release upgrade because system would not know the configuration for your board.
Started User Manager for UID 123. Problem . - #2 by linuxdev

If you could not boot the device now, I would suggest you to re-flash the board.

Thank you for your prompt reply. For your information, I am using orin Development kit. Is there any other way to solve the issue without re-flashing the board.

If you are using the devkit, I would suggest flash the board with SDKM.

If you don’t want to re-flash the board at this moment, please provide the serial console log for further check. We have to know what happened inside now.
