Greetings Everyone,
I’m having an issue with my EM7455 Firmware on my Thinkpad T470. The issue is that each time I try to update the firmware and after succeeding, for some reason it rolls back to the previous version which is 02.24.05.06. The version that I’m trying to upgrade to is 02.32.11.00. I don’t know if Thinkpads are not allowed to perform firmware updates, but after updating the firmware and reboot the device it goes back to the older version which is 02.24.05.06.
Thanks.
Do you have a SIM inserted and who’s the carrier? The module may have been defaulted to use firmware 02.24.05.06 for certain reasons such as if it’s the carrier certified firmware where the one 02.32.11.00 you flashed might not have been approved by the carrier yet.
Also, where did you get the 02.32.11.00 firmware and what is the Mobile Broadband Driver Package version you are using now? You can find it in \Control Panel\Add Remove Programs.
I’m currently using a VIVA sim card. I’m located now in Kuwait Middle East. It’s a regular data sim card. I don’t think that the carrier knows anything about this because when I talked to them about the internet sim card they just told me to plug it and it should work.
For the driver, I’m using the one provided by Lenovo Drivers Page which is 7.70.4957.0103.
The Website that I’m downloading the firmware from is the following:

The version that I’m trying to install is the one that’s highlighted in Yellow.
Did you ever get an answer or figure this out? I’m having the same issue when I try to install Verizon 2.33 from 2.24. It keeps rolling back after reboot
We are having the same issue here with with over a hundred Panasonic FZ-55 Toughbooks with EM7511 modems with Verizon SIMs.
They were all running version 1.14.02, but we need to be running the newest Verizon certified, SWI9X50C_01.14.24.00, do to a bunch of GPS NEMA fixes required for the CAD software they are using.
I pushed out a script to update the firmware on them that does an AT!IMAGE=0, reboots the card, verifies that all the firmwares have been erased, and then runs fdt2.exe to install the new firmware and carrier file, and then verifies the install and the preferred firmware is set correctly.
It works successfully on majority of them, but now we are finding after a few days over half of them have reverted back to the original 1.14.02 firmware and once again having issues with the CAD software.
I’m guessing this firmware version is being pushed by Verizon, since I completely blew all the firmware off the card and it is somehow ending up back on there.
Why is Verizon pushing such an old ass firmware, when there is a much newer approved version?
How do I STOP Verizon from being able to push this old firmware to the device and get it to stay on the new one?
I brought this up with our Verizon account rep about why they are pushing out such an old firmware and he says he has never seen this before and has no idea.
