DS7 Crossback – Firmware-update issue

Hi all

Today I attempted to install the latest firmware update on my 2021 DS7 Crossback E-Tense Plug-In Hybrid using the official DS Update Tool.

The installation started normally, but after a few minutes I received the following error messages:

  • “Firmware update error! Please remove the USB stick.”
  • “Software loading on demand… System has limited functionality.”

Since then, the screen remains stuck in this limited mode. Navigation, radio, and most system functions are no longer working.

So far, I have:

  • Reformatted the USB stick
  • Re-downloaded the update via DS Update
  • Restarted the system multiple times

Unfortunately, the update fails every time.

Has anyone experienced this issue or knows how to fix it?
Thanks in advance for your help!

This message always appears during the update, which takes about 45 minutes. The engine must be running during this time.
