Doubt regarding SDK manager

Hello Guys I have doubt regarding SDK manager installation like I am planning to downgrade from jetpack 6.1 to jetpack 5.


In the step2 part I have a doubt regarding the Download folder and target folder because I have inserted the SDcard in the jetson orin nano itself and Connecting it so for the download folder and target folder what should I select.

It does not matter. Those path are not related to your sdcard.

It is just where the flash tool will be put into your host PC. The flash tool will flash your sdcard though usb cable between Jetson and your host.

Hello @WayneWWW Can you please help me with this


I have attached the logs in the above

The 3 logs you shared are all different cases

first log indicates your board is not in recovery mode

second log indicates a weird error which needs something else to check further.

The 3rd log which is your screenshot does not have any error but seems just in the middle of flash. What is the result in the end from your 3rd log?

Hello @WayneWWW, there is no third log I just take screenshot of it while performing the 2nd log

Is your host machine a VM? or it is native ubuntu host?

Yeah it is a VM only.

Please use a native ubuntu host as VM has unstable usb link connection.

Ok let me try

Hello @WayneWWW I have tried with native ubuntu host but still it is not working like the device is already in recovery mode only. but still it doesn’t work

Are you sure your type C cable is okay? How about changing it to other kind?

Hello @WayneWWW I have tried with different cable as well but it is also not working with that.

Please use Manual Setup if your board has been in force recovery state already.

Have you confirmed that you are connecting only one Jetson device?

Have you confirmed that you are using the Orin Nano devkit?

Hello @KevinFFF, I have been using the jetson orin nano devkit only and I am connecting only one device.
I have tried both Manual and Automatic setup in the SDK Manager.

Is there any other way to downgrade from jetpack 6 to jetpack 5

Hello @KevinFFF and @WayneWWW Is there any other way to downgrade it from jetpack6 to jetpack5 other than SDK manager if it is there please give me step by step instructions to do that.

Hello @KevinFFF I have tried with this method
https://docs.nvidia.com/jetson/archives/r35.5.0/DeveloperGuide/IN/QuickStart.html#to-determine-whether-the-developer-kit-is-in-force-recovery-mode

downloaded these things

and tried to downgrade it but it is not downgrading I am attaching the logs for further reference.

Hello @KevinFFF and @WayneWWW can anyone of you help me to solve this issue please.

Try this method to dump the serial console log from the device side during flash failure.
