[EasyNetDev]

Hi all,

This tool is able to unlock DW5934e WWAN cards with Snapdragon X72 5G Modem?

Thanks in advance.

Hi，
This tool only applicable for these permitted platforms with DW5934e.

Could you show me the response of command "dmidecode -t 1"?

After I emulate SKU 0CE3 I got this output:

Your platform 0CE3 support FccLock!
AP version AP020 lower than Target version AP047. Please uprgade FW to AP047 firstly!!
FCC unlock stopped!!

There is a way to upgrade firmware in Linux for this device?

You can do a firmware update by LVFS. Something like "sudo fwupdmgr refresh --force""sudo fwupdmgr update"

Thanks for info. Unfortunately fwupdmgr doesn't show this card in the list:

# lspci -s 0003:01:00.0 -nn

Hi，
Both your SKU ID is not a real DELL supported platform, and your FW is not an official release version. Please contact with DELL official support firstly.

[EasyNetDev]

Ok. I was able to put the device in QDL mode:

Bus 001 Device 003: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

And if I'm using qdl list I got this:

# qdl list
05c6:9008       31C1B4BF

But qdl request a prog.mbn file. In LVFS cab files I couldn't find any .mbn file, just ota.bin and some XML files.

Looks like one of the modems I was able to upgrade but is detected as:

0003:01:00.0 Unassigned class [ff00]: Foxconn International, Inc. Snapdragon X72 CAT 20 5G network card Wireless Mobile Modem [105b:e11d]

The second which I can't upgrade it:

0003:01:00.0 Unassigned class [ff00]: Qualcomm Technologies, Inc SDX72 [Snapdragon X72 5G] [17cb:0309]

This is one issue with fwupdmgr.

The second issue is even first modem is upgraded to AP047, the tool is not able to unlock it. I've tried multiple SKU and none of them is unlocking the modem:

[105b:e11d] shall be the expected VID/PID settings.
For unlock fail issue, I can't provide help on that since this project is responsible to DELL only.

==>Your actions have harmed Dell's interests. It's recommended to buy the DELL platform with this WWAN card.
If you want same modules only, you can contact with Foxconn Sales.

Hi,

Looks like after booting into Windows, even modem with firmware upgrade from AP020 to AP047 was downgraded to AP034.
The modem was changed from firmware:

FDE2.F0.0.0.1.2.GC.001.047

To

FDE2.F0.0.0.1.2.CE.001.034

Linux fwupd doesn't have any version firmware for CE version, but for GC has. That's why the second modem wasn't able to update to AP047.
But unfortunately the modem which was working now has the same firmware as the one with AP034 CE.
I used Dell-Wireless-5934e-and-Qualcomm-Snapdragon-X72-Firmware_MNK8X_WIN64_0.1.0.30_A08_03.EXE this driver and firmware for Windows and I ended in this downgraded firmware version.
Why doesn't exists firmware upgrade for CE?

[SlarkXiao]

Normally only AP047 and above shall be published. CE and GC are the carrier vendor information (belongs to minor version), not the major version.

If possible, you can get the latest version (not AP034) from Windows side and have a try.
In Linux side, AP047 is the lowest version. And only specific VID/PID devices could be allowed to do a LVFS.

[EasyNetDev]

I found a solution to upgrade both modems to AP047 and the fwupd updated to AP060.
Here I described the solution: fwupd/fwupd#10054
On Dell site that EXE is the latest one. Is from January 2026 or something like this. So, Microslope is completely useless.
