The EM7455/MC7455 is a Category 6 LTE modem. It is capable of 300Mbps down and 50Mbps up.
Real world, you are unlikely to ever see much more than 230Mbps, even on Sprint Carrier Aggregation of Band 41+41 (40MHz total).
These are my peak results so far (B2+B12, 30MHz total):
Higher speeds will require a modem capable of 3CA (Three Carrier Aggregation) such as the em7565

Successful flash of EM7455, no power light after
I have an EM7455 and am using an external enclosure with a bright blue power light. Prior to flashing the power light would come on after a bit.
After flashing successfully, the power light only flashes briefly after USB is plugged in and then there is no light after that.
Stuck in boothold wait
Describe the bug
I have an EM7445 which I flashed using the autoflash script over a year ago. Recently, it stopped connecting to the carrier, so, I thought maybe my firmware needs an update. I tried to use the autoflash script again, however, this time it gets stuck in the boothold wait.

Manual Flashing Procedure references bad URLs
The manua flashing procedure is linking to some now missing URLs (for example, wget http://security.ubuntu.com/ubuntu/pool/universe/libq/libqmi/libqmi-utils_1.20.0-1ubuntu1_amd64.deb
). I think it would be best to actually just update everything to cosmic as it has the required newer packages in the archive. Baring that, we can update the links to point to a ppa or something more stable; or really ideally, find a better distribution method. Thanks for documenting all of this!

Device stuck in QDLoader
Hi Daniel,
I’m trying to recover an EM7455 that I got stuck in QDLoader mode. Following your notes and using an 18.04 image I see this device id in lsusb:
Bus 003 Device 010: ID 1199:9078 Sierra Wireless, Inc.
Correct method for latest firmware.
This may seem like a simple question to you Linux guru’s, but please remember not all of us are 🙂
In the autoflash-7455.sh script, could I have example of using latest firmware SWI9X30C_02.33.03.00_Generic_002.072_000.zip (least current at time of this post)?
I thank you in advance!

Firmware update not working on an 02.08 Dell EM7455
qmi-firmware-update fails every time after it restarts the modem in boot & hold mode with either of the following two errors (roughly 50:50 chance), running on Ubuntu 18.04.5 in VMware on a Windows 10 host.
After that, the modem is stuck in low-power mode because the firmware image preference refers to the image that is not yet flashed to the modem, hence mismatching the one loaded by default.
Updates with fwdwl-litehostx86_64 (Ubuntu 18.04.5) and fdt.exe (Windows 10) fail too.
I have some problems after running autoflash-7455.sh

Can’t restore EM7565 from QDLoader mode
All to no avail, the behavior of the modem does not change. All the instructions I found on the net do not work.
There is an assumption that the modem has finally become corrupted, but I would like to believe that it can be restored.

Setup without external enclosure
Hi, thanks for all your work on this repo!
I have a Thinkpad T460s and I’d like to install the card internally. The README says that the instructions only work for an external USB enclosure. Is it not possible to setup the modem when it’s installed internally, or would it just requiring modifying the procedure?

If I try to send via AT commands it says there’s no room. When I moved back to another phone or other device running Linux with a different modem it sends with no problem with commands above. All msgs come in and send once the sim is placed in another device.

Auto flash script fails at trying to pull FW from sierrra’s website
Hi @danielewood Daniele & Team
Thank you very much for your contributions to the wireless LTE community in getting the EM7455 dell / lenovo to work as generic.
the error is something about file size not matched, would really appreciate if you can help with this.
I managed to get in USBCOMP=8 mode and manually reflashed using Sierra tool on windows but the auto flash script would be super for saving time in case it gets (EM7455) to DW5811e.
Thank you very much!
Autoflash not working cause Download URL changed
Hi,
i tried using the autoflash script on a Ubuntu 20.04 Live System.
It seems that everything works until it gets to the part where it wants to download the Generic Firmware.
Stops there cause of this error: https://github.com/danielewood/sierra-wireless-modems/blob/master/autoflash-7455.sh#L318
But simply changing the URL in line 308 https://github.com/danielewood/sierra-wireless-modems/blob/master/autoflash-7455.sh#L308
did not work.
I think the whole part about the Download URL and filename needs a few tweaks, but sadly I cant figure out whats wrong.
Would be nice if that could be upgraded!?
qmi-firmware-update does support EM75xx family, and EM91xx as well

The README says «For qmi-firmware-update does not work with the 75xx series». The tool does support EM75xx, and since 1.30.4 it also supports the newer EM91xx as well.
Can Lenovo branded EM7455 change identities?
Can Lenovo branded ones have their identities changed? Or only the Dell ones allow for it? Thank you.
T480/EM7455 confirmed working but need to block some pin
Need to block 29,31,35,37 pin(force to use USB 2.0 interface).
27,33,39 are GND pin so you can block it as well.
Maybe conflict with Motherboard PCIe pin?
