Jetson Nano eMMC Stuck at NVIDIA Logo After Update - Recovery Mode USB Detection Failure

[juanmil.mar26]

Issue Description:
After performing a routine sudo apt upgrade on my Jetson Nano Developer Kit (eMMC version, P3448-0020), the device freezes indefinitely at the NVIDIA logo screen during boot. No progress to login.

Steps Taken to Resolve:

1. Attempted Force Recovery Mode per L4T Quick Start Guide:

   • Shorted pins 9-10 on J50 header (B01 revision).

   • Enabled DC power via J48 jumper.

   • Confirmed no LEDs active except power (indicating recovery mode).

2. Prepared Ubuntu 22.04 LTS in VirtualBox (Windows host):

   • Downloaded L4T R32.7.3 + Sample Root FS.

   • Ran apply_binaries.sh.

3. Critical Problem:

   • Jetson not detected by Windows Device Manager (no “APX” or “NVIDIA USB Boot” entries).

   • No recognition in VirtualBox despite:

     • USB 3.0/xHCI controller enabled.

     • Extension Pack installed.

     • Manual filters for 0955:7f21.

     • Udev rules added in Ubuntu.

Request:

• Guidance on:
  a) Alternative recovery methods for boot-loop post-update.
  b) Hardware verification for eMMC failure.
  c) Windows driver solutions for 0955:7f21 detection.

System Details:

• Jetson: Nano Developer Kit (4GB, eMMC, Rev B01).

• Host: Windows 11 + VirtualBox 7.0.12.

• L4T Version: R32.7.3.

Please have a native Ubuntu OS PC to flash you device, there are some problem on Windows + VituralBOX.

FYI, sometimes people do get a VM to work, but it has to be configured to always pass that USB device through. Even if the VM initially detects the Jetson it is common to lose USB during flash because the USB will disconnect and reconnect, but the VM often loses reconnect. Every VM is different and the flash software has no ability to configure the USB of a VM. You would be far better off with native Ubuntu 18.04 for L4T R32.x, e.g., adding a second hard drive and dual booting.
