Hi!
I Running EM7455 in DELL 7370 laptop.
I already setup newest windows driver (4836) and tried to flash lates FW (02.32.11)
Currently i have no issues in windows device manager, but no connection to LTE network
My network is MTS Russia. So, i try to use Generic profile
Where did you get the EM7455 module? The USB PID and VID on your module are generic but not programmed for Dell. It won’t work on Dell laptops due to the BIOS locking.
Also, the module didn’t show any record in our system so we don’t know the history of it at all. You may want to get one from Dell or at least one that was SKU’d for Dell.
i got it from ebay 1 year ago.
initially it was dell module, but after i tried to install dell firmware from official site -it goes to reboot on 37% and i decide to flash it to generic
so - am i understand correct i need to reflash it to dell and flash it&
Change PID and VID to make generic using:
– AT!UDPID=9071,9070
– AT!UDVID=1199
– AT!RESET
Uninstall the dell driver ( Communications_Driver_R9YXH_WN32_7.8.4376.507_A01.EXE)
Install to the latest Sierra Generic windows driver (GenericDriverSetup_4773.exe)
Upgrade to the Sierra generic firmware 9999999_9904609_swi9x30c_02.24.05.06_00_GENERIC_002.026_000
– fdt.exe -d 9x30 -f SWI9X30C_02.24.05.06.cwe SWI9X30C_02.24.05.06_GENERIC_002.026_000.nvu
Run AT!PRIID command to point to the firmware and done?
i got matching in carrier name and upgrade to latest Generic software
but module still not working

ok.
Solution for me - back to dell 01.08.07. I load dell spk file - as recomended in forum - and all works!
LTE working perfect.
But issue that in device manager i can see 2 unknown devices without drivers, and cant load driver from dell package manually. And, moreover - i can flash from this fw to any else -becouse can open port in fdt2.exe
So solution:
0) Install Sierra Wireless Mobile Broadband Driver Package for Windows without flashing any fw
Flash Generic PID and VID
at! reset
Flash 01.08.07 from SPK file - PID&VID will change automatically
Profit
Only issue that i have 2 drivers in Windows device manager, which i think i neet to replace for DELL one, but unfortunately a can’t install them from exe - becouse it starts fw flashing and reboots after 37%…
But at least i have working modem now
