Jetson AGX Orin 64GB - Cannot complete clean flash, multiple methods tried

Hi,

I’ve been trying to flash JetPack 6.2.2 on my Jetson AGX Orin 64GB Developer Kit for several days. The device was originally on JetPack 5.1.3. I’ve tried every method I can think of and none have worked. Hardware is confirmed working — CLI boots fine, internet works, nvidia kernel modules load.

Here’s everything I’ve tried:

  1. Windows WSL2 + SDK Manager
  • USBIPD USB binding errors
  • “non-optimal USB connection” error
  • Flash was “Skipped”
  • APX driver installed via Zadig successfully, but flash still failed
  1. Ubuntu 22.04 Live Boot (USB) + SDK Manager
  • RAM-based storage (~7GB /cow) too small
  • NTFS symlink/permission issues caused tar errors
  • Image build succeeded but flash failed with USB timeout
  1. Ubuntu Live Boot + flash.sh (command line)
  • “ERROR: might be timeout in USB write” repeatedly
  • Tried disabling USB autosuspend (echo -1 > /sys/module/usbcore/parameters/autosuspend) — same error
  1. Ubuntu 22.04 Native Install (ext4, on external SSD) + SDK Manager
  • Jetson detected in recovery mode (APX confirmed via lsusb)
  • “The connected Jetson device is not ready for flash” / “non-optimal USB connection”
  1. Windows SDK Manager after update to 2.4.0.13236
  • “No SDKs are available for your account” — persists after reinstall, logout/login, reboot
  • Same account works fine on Ubuntu SDK Manager 2.4.0.13236
  1. Current Jetson state (after partial flash.sh)
  • R36 REVISION 5.0 (JP6.2.2) is on eMMC
  • CLI works via tty, internet works, nvidia kernel modules loaded
  • GUI does not work:
    • Xorg: “eglInitialize() failed”, “No modes”, “no screens found”
    • Weston: “NvRmMemInitNvmap failed with Permission denied”, “NvRmMemMgrInit failed error type: 196626”
    • /dev/nvhost* devices do not exist
    • /dev/dri/card1-DP-1 status: Connected
    • nvidia-l4t packages (36.5.0) all installed

Host PC: AMD desktop (B650 AORUS ELITE V2, RTX 4060 Ti)
USB cable: USB-A to USB-C (connected to USB-C port next to 40-pin header on Jetson)

Questions:

  1. Is the USB timeout issue related to the AMD USB controller? Would an Intel-based host resolve this?
  2. Is there a way to fix the current partial flash state from tty (restore /dev/nvhost* devices, fix GUI) without a full reflash?
  3. Any known fix for SDK Manager 2.4.0.13236 on Windows showing “No SDKs available”?

Any help would be greatly appreciated. Thank you.
