your link for "Firmware Update Mod for Dell 5530" is not working more. I have downloaded the original file from DELL Dell_Wireless-5530-HSPA-Mini_A01_R212325.exe and extract then (D5530_R1D06.exe).
My ERICSSON F3507g WWAN adapter is Lenovo branding and have the hardware ID "USB\Vid_0bdb&Pid_1900&Rev_0000&Mi_05&Os_NT" in device manager.
When you run D5530_R1D06.exe it shows me the current status, but will not update the firmware (error: "The install package doesn't support the installed Mobile Broadband Module hardware version").
Current status bevor error:
FW Updater - CXP9013117_10-R1Z03
Hardware Version KRD 131 14/202 R1G
Current Firmware Version R1A034
Current Firmware Build Date 208-05-17 06:58
Can you help to mod the dell firmware to accept the Lenovo branding to, or what should I do?
