Sierra Wireless LTE Modem Guide: Automated Flashing of the EM7455/MC7455 with a Ubuntu Linux 18.04 LiveCD
I've written a bash script to automate the entire process of setting up any of the EM/MC74XX series modems (Generic, Dell, Lenovo). This assumes you have the Sierra card inserted into a USB enclosure.
This post is part of my Sierra Wireless LTE Modem Guide Series. If you prefer to skip the blog nature of these guides and just grab the bare features and commands, my GitHub repository will serve as the authoritative source for this entire series. Any changes or updates will occur there first.
From the script description:
- Only for use on Ubuntu 18.04 LTS LiveUSB
- All Needed Packages will Auto-Install
- Sets MBIM Mode with AT Commands Access
- Changes all models of EM74XX/MC74XX Modems to the Generic Sierra Wireless VID/PID
- Clears Band Restrictions and Places Modem in LTE only mode.
- Flashes the Current Generic Firmware as of 2018-07-18
Link to script:
https://github.com/danielewood/sierra-wireless-modems/blob/master/autoflash-7455.sh
If you are feeling brave you can run the script with:
wget https://raw.githubusercontent.com/danielewood/sierra-wireless-modems/master/autoflash-7455.sh && sudo bash autoflash-7455.sh
Video of the entire process:

DeleteHello,
ReplyDeletewhy you write it is just for USB enclosure and not if you have a installed card (Dell notebook)?
is there any way to use this also for attached cards?
Thanks so much. Saved my card which wouldn't connect after a failed flash attempt with windows. I believe the comm ports where scrambled and had tried everything I knew before finding this. Didn't use the full usb enclosure but a cheap $7 bare board. It all went perfectly.
ReplyDeleteHi Daniele
ReplyDeleteI just wanted to let you know the script in ubuntu 18 LTS fails at the CURL trying to pull the latest Sierra firmware from Sierra website, can you please see why when you get a chance? It says file either too large or too small, and then the script craps out.
Thank you very much
James.

Hi
ReplyDeleteI am facing QMI Protocol error (14) callfailed with sierra wireless EM7455
Thanks & Regards,
M.Abinaya
Many thanks for this great tutorials, My EM7455 is now working as usual.
ReplyDeleteThanks for putting this together, however I am getting the error:
ReplyDeleteloading device information before the update...
error: couldn't open QMI device: Failure
firmware update failed, exiting...
does this not work for onboard cards? or only usb?
I downloaded ubuntu 18.04.5 instead of the current version and it was able to complete but I am still not able to get online, nor will the firmware for my provider will not install. I must have a bad card.

Getting same error, Did you find a solution?
ReplyDeleteFor me, it ends with cat: /DEV/TTYUSB3 : Not such file or directory
ReplyDeleteAnd the modem is not operational afterwards, so I guess something failed, but I don't understand what and where…
The above-mentionned error was for Ubuntu 20.
DeleteUnder Ubuntu 18, I got the same mistake as mutalib and Dougf :(
Change the command to --update-qdl in the script and it should work.

Done!
Is it OK?
Had been googling basically the whole Internet before finding this blog post from your GitHub repo.
ReplyDeleteI bought an em7455 on Ebay and realized it was Dell branded. Managed to flash it using a Ubuntu 22.02 Live USB stick. I had to run it once manually to just do the rebranding part since that didn't work when running it without arguments, not sure why but in the end it worked out great.
Thank you so much for putting in the effort to providing this!
Cheers,
Johan

If you are planning a trip abroad, a travel SIM card can be a useful way to stay connected. These SIM cards are designed specifically for use while traveling and can offer many benefits, including lower rates for international calls and data usage. Travel SIM cards can be purchased from many different carriers, so it is important to compare rates and features before choosing one. Travel SIM Card

really gutting this isnt fixed, ive been trying to solve this for two days straight and nothing but problems.. even tried to use ai to fix the download script issues and getting no where. installed live cd of ubuntu 18.04 - dont bother the script now says its ubuntu 20 as a minimum... another waste of my time faffing about with bios, virtualisation and other such bollocks to do with flashing this module.
I am in the same situation with the same-same error: I tried both with annoroginal Lenovo Sierra 7455 (01AX748) and with a Dell-branded one: same error. Not sure it is because I am trying to do everything from the WWAN slot and not from an USB enclosure BUT module getsbrecognized by the script so I do not think that is the real issue...
