hello bugrayildirim463,

you’re installing JetPack-4.5 with NVIDIA SDK Manager | NVIDIA Developer, right?
there should be Jetpack release image install to your local machine, you’re able to execute flash script to re-flash your Jetson-TX2.
for example, ~/nvidia/nvidia_sdk/JetPack_version_platform/Linux_for_Tegra/

please check developer guide, Basic Flash Script Usage to re-flash your platform,
thanks
