New Sierra Wireless EM7345 firmwares available

Yesterday I’ve been checking on Lenovo drivers website and have noticed that they added the X250 model. And what did I find there?¬†Sierra Wireless EM7345 Software for Windows 8.1 (32-bit, 64-bit) – ThinkPad version¬†1.11.10610.4225 , released on 12/16/2014 . So Lenovo doesn’t update WWAN drivers for their “old” models, like X240 or T440 and the latest drivers out there are dated July 31. So I downloaded it, unpacked it and found the following EM7345 firmwares inside:


  • FIH7160_V1.1_WW_01.1410.13_AT_NAND.fls version 1.1 (1410.13) for AT&T (United States only) dated 2014-May-19 12:32:21
  • FIH7160_V1.2_WW_01.1415.07_NAND.fls version 1.2 (1415.07) Worldwide dated 2014-Jun-5 11:54:58. This is the version I had flashed into my EM7345, as described in this post
  • FIH7160_V1.2_WW_01.1415.09_NAND.fls version 1.2 (1415.09) Worldwide dated ¬†2014-Oct-22 17:47:10. Seems to be an update for 1415.07.
  • FIH7160_V1.2_WW_01.1442.04_VZ_NAND.fls version 1.2 (1442.04) for Verizon (United States only) dated 2014-Nov-20 11:23:44

Of course I couldn’t resist and flashed the new firmware FIH7160_V1.2_WW_01.1415.09. Everything seems to work fine.

I didn’t dare to flash Verizon or AT&T version, even though Verizon seems to be the latest, compiled on 2014-Nov-20. US operators love to SIM lock their devices, and those firmwares can be locked. Unless you are in the US and your network is Verizon/AT&T or you just don’t care, I cannot recommend to flash those AT&T and Verizon firmwares.

How to flash it? Just put file FIH7160_V1.2_WW_01.1415.09_NAND.fls into the folder “c:\ProgramData\Intel\MBIM Toolkit\FirmwareDatabase\PreInstalled” (first you have to have the EM7345 drivers installed as desrcibed in this guide ) and make changes to file “c:\ProgramData\Intel\MBIM Toolkit\FirmwareDatabase\PreInstalled\FLSInformation.xml”. But this time use FIH7160_V1.2_WW_01.1415.09_NAND.fls instead of FIH7160_V1.2_WW_01.1415.07_NAND.fls when editing the xml and you’re done.

After reboot, you will be prompted by the Intel firmware updater:


Press Yes and you’re set! Interestingly, VID/PID weren’t reset to their default values so I had no need to restore them. Also GNSS and AT ports were not affected at all, and continued to work just fine.

I’d like to know what new features and bug fixes are brought by the updates, but (as usual) we have no information, no change logs… I’m not using my EM7345 much these days, but if you guys notice something new in this update, feel free to let me know.

  • Gave this a go, even though I’m on Win7Pro = unsuccessful attempt to update. So my guess is there are preconditions checks by the firmware updater and OS version is one of them.

    • What error did you get? I’m always using Win 8, as Win 7 drivers are known to filter any “non-standard” MBIM commands going to the device, like composition change or device reboot into firmware download mode.

      Microsoft’s standard MBIM drivers built in Windows 8 never do any filtering. But I never tried Win 7 with the above new Lenovo drivers. You can just uninstall the old EM7345 drivers from the Control Panel and install the new drivers, then use my instructions to update the firmware. Maybe it will work on Win 7 with the new drivers. BTW, the new drivers do silent firmware upgrade to version 1415.07 for ALL SIM cards, besides Verizon and AT&T. So be careful and don’t reboot right after you install the new drivers, wait at least 5 minutes, than check the firmware version (AT+XGENDATA)

      • With silent updates enabled, it says “Firmware Update Failed. Do you want to attempt to install again later?”. When following your instructions to force the update, the firmware update tool hangs and then disables the WWAN card. I even tried removing the lines for the default use of the version ending .07 which results in it being completely unavailable.

        It seems that either it’s Win7 and or something on my laptop. Either way, it seems stable enough on the previous version. So it’ll have to do for now.

        The only problem I’ve noticed recently is my WWAN card seems locked to using LTE only. Before it would fall back to using 3G if the 4G signal was weak but it doesn’t seem to do this any more. Is there a way to reset the band selection (other than sending AT&F which I’ve tried unsuccessfully) on these cards?

  • Has anyone tried the 1415.09 version in ThinkPad 8 tablet ? Currently I use 1415.07 but there are still issues.

  • Hello Zukota,

    Would you please let me know where i can download firmwares such as FIH7160_V1.2_WW_01.1415.07_NAND.fls and FIH7160_V1.2_WW_01.1415.09_NAND.fls?
