Hi ModalAI Team,

I'm trying to flash the following flat build to my VOXL 2:

Build: 2024-06-17-1.7.4-M0054-1
Board: M0054-1
Tool: QDL Tool (GUI version)
Status: Device is detected – QDL device connected: Qualcomm Gobi Wireless Modem

However, the flashing process fails during the sahara_run step. Here's the output from the log:

Flashing Flat Build…
{"message": "modal hello\n[MODALAI] test log\n\n[MODALAI] Executing usb_open\n[MODALAI] Completed usb_open\n[MODALAI] Executing sahara_run\n\n\nFlash flat build failed\n"}

Despite the GUI showing “Flash flat build succeeded” in green at the bottom, the log clearly indicates a failure in sahara_run.

What I’ve tried so far:

    Multiple USB ports and cables

    Power cycling the board

    Re-downloading the build

    Running as root / with permissions

    Ensuring no other process is using the USB port

Any suggestions on how to resolve this or what might be going wrong?

Thanks in advance!![7274d094-adfa-4627-afcd-bdb1fac9e4c2.png](https://forum.modalai.com/assets/uploads/files/1751528335782-7274d094-adfa-4627-afcd-bdb1fac9e4c2.png)
