RUBIK Pi 3 V02 — Cannot enter EDL mode

Canonical Ubuntu Ubuntu OS issues
1

I’m not able to enter EDL mode on my RUBIK Pi 3 (V02). Nothing appears in Device Manager when attempting it or Qualcomm Launcher.

Symptoms:

  • Green heartbeat LED flashes
  • UART: COM3 detected but no serial output
  • SSH no longer works
    -EDL: nothing appears in Device Manager using any of the 3 documented methods

I have tried all official EDL entry methods multiple times on both Windows and macOS, with the correct ports and drivers properly installed.

Any advice?

What’s the previous status of the board? Can it boot up? Can you see log output during boot? If yes, that’s normal because there’s no log for EDL mode, before real flashing occurs.
If you cannot see any log output, even for the normal boot, I guess there might be HW issue.

You can also try the EDL mode with Linux host. Under Linux, you can use “lsusb” command to check whether it’s in EDL mode. There should be an USB device like this:

Bus 003 Device 009: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

Then you can use qdl command to flash. qdl can be installed by apt under Debian/Ubuntu.
