Request for Recovery Guidance – NVIDIA Shield TV Pro (2015 – 500GB stuck in APX mode)

Hello NVIDIA Developer Community,

My name is Mohammad Al-Tamimi and I am based in Saudi Arabia.
I own an NVIDIA Shield TV Pro (2015 – 500GB version with internal HDD).

Unfortunately, my device no longer boots into Android, recovery, or bootloader.
It is only detected by my PC as APX (NVIDIA Tegra Recovery Mode).

I have already tested multiple recovery methods (fastboot, ADB, fusee-launcher, etc.) but none worked. The device seems to require signed keys to boot.

I kindly request your guidance on the official procedure for recovery:

  • Is there any official recovery/factory image or signed package that can be used from APX mode?
  • If not, is there an RMA or repair path available for out-of-warranty Shield devices (especially in Saudi Arabia)?

Details:

  • Model: NVIDIA Shield TV Pro (2015 – 500GB HDD)
  • Serial Number: [I will provide it when I have access to the device]
  • Country: Saudi Arabia
  • Contact: hercules5065@gmail.com / +966530669068

Thank you in advance for your help and guidance.

Best regards,
Mohammad Al-Tamimi
