RealSense D455 not detected by SDK/Viewer, firmware update not possible
Hello Intel RealSense Support Team,
I have an Intel RealSense D455 (Serial: 218523067624) which seems to be bricked.
When connected via USB, the device is detected by the OS as "Intel(R) RealSense(TM) Invalid SKU" (VID 8086, PID 0af5).
- On Ubuntu 20.04 and Windows 10, `rs-enumerate-devices` and RealSense Viewer do not recognize the camera.
- Attempting firmware recovery with `rs-fw-update` always fails with "No devices were found" or "No recovery devices were found".
- Tried multiple firmware versions (5.13.0.50, 5.12.15.50, 5.12.18.0) and both USB 2.0 and 3.0 ports. Same result.
- Different cables and hosts tested.
- The device consistently shows up as "Invalid SKU" and cannot enter recovery mode.
It seems the firmware bootloader is corrupted and the device is not recoverable by standard tools.
Could you advise on RMA or repair/replacement procedure?
Thank you.

Hello, an Invalid SKU error indicates a problem with the firmware driver. On a D455 this could be caused by installing a firmware version older than 5.13.0.50, as that is the minimum firmware that supports D455.
If your camera was purchased longer than 12 months ago it would be outside of its warranty period for replacement. And the Invalid SKU error is not fixable by users with a software update, unfortunately. Self-repair options would be to open up the camera casing and either:
1. Replace the Vision Processor D4 V3 board with a new one. These can be purchased from RealSense parts suppliers for around 50 euros / dollars. Or:
2. Purchase a D430 depth module, attach it to your camera's Vision Processor D4 board and perform a firmware update, then re-attach your camera's original D450 depth module. This would be the more expensive of the two options.
If the camera was purchased less than 12 months ago and is still within the warranty period, may I ask which country you are located in please.
