Recovering Flight Logs from a Bricked VOXL2

[lhermosillo]

Hi all,

I'm attempting to recover the last flight logs from a VOXL 2 that suffered a crash. The VOXL 2 appears to power on normally (LEDs light up, board shows no visible damage), but it will not allow me to connect via ADB, SSH, or fastboot.

When connected to a PC, the device shows up as: Qualcomm HS-USB QDLoader 9008, so EDL.

My goal:
I'm trying to recover flight logs from the onboard UFS storage before re-flashing the system image.

What I've tried:

• Installed Qualcomm USB drivers to recognize Qualcomm HS-USB QDLoader 9008 as COM5
• Installed QPST/QFIL 2.7.460 (digitally signed Qualcomm build)
• Tried accessing partitions via QFIL's Partition Manager using various prog_firehose_ddr.elf files
  Every attempt so far results in:

ERROR: function: sahara_rx_data: Unable to read packet header. Only read 0 bytes.
ERROR: function: sahara_main: Sahara protocol error
ERROR: function: main: Uploading Image using Sahara protocol failed
Download Fail: Sahara Fail: QsaharaServer Fail: Process fail

Hardware Information:

• Model: VOXL 2 (M0154)
• Software was likely VOXL2 SDK 1.40?
• I've accessed VOXL2 QDL Image 14.1a_1.7.8, VOXL2 QDL Image 14.1a_1.1.2, and M0054-2 Starling QDL Image 1.7.4, for their prog_firehose_ddr.elf files and none have worked.

Questions:
Before proceeding with ModalAI's QDL web-based flashing tool (which I understand will wipe the UFS storage), I'm trying to confirm:

• Is there a VOXL 2 M0154 specific QDL image that includes the correct prog_firehose_ddr.elf for data recovery?
• Can the modal-qdl CLI or GUI tools be used in a non-destructive way to read partitions, similar to QFIL's "Read Data" function?
• If not, is there any safe way to extract the partitions regarding flight logs before flashing the board back to factory state?

System Setup:

• Host: Windows 11 + Ubuntu (WSL2)
• Device Manager shows: Qualcomm HS-USB QDLoader 9008 (COM 5)
• When attaching the Bus ID from Windows to WSL, lsusb shows: Bus 001 Device 003: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

Any help or access to the proper prog_firehose_ddr.elf for M0154 would be greatly appreciated.
My main priority is preserving those flight logs to narrow down what went wrong during a simple arm test.
