This could be a firmware issue. Have you tried flashing the Generic firmware on the MC7455?
hi again Jim - I've tried so many different things, I'm pretty sure I've done the generic firmware. I've been trying to scour the LTE hacks support site for other articles to try and troubleshoot on my own, but I'm not seeing anything along the lines of what im experiencing :?

So you are saying that you did reflash the firmware on the MC7455? You would need a USB to Mini PCI-e adapter to flash the Sierra Wireless generic firmware.

You would also have to remove the MC7455 from the router to flash--or at least that would be the easiest method.

Where did you get your MC7455?

From the sound of it, no I guess I have not done that yet...I'll have to put an adapter on order and try that out. Thanks for the recommendation!

I got the mc7455 from a reputable electronics reseller..it was used, but tested to work properly.

The modems inability to accept an AT+CFUN=1 is a good sign it may be modem related.

Hopefully, it can be corrected by flashing with the latest Sierra Wireless Generic firmware.

There is always a gamble when buying used modems or any equipment for that matter.

Hello again, after several months I finally had the courage to try again. I purchased the USB adapter in order to connect the modem directly to the computer. I ended up having the same issues as this user.

I downloaded the most recent Generic firmware, followed all instructions and even followed the Tool Kit posted in here, and keep getting "The connection for the USB device 'Sierra Wireless MC7455-CP' was unsuccessful. Driver Error." when I run connect through HT then try to install the firmware. I have tried variations of everything I have found posted on LTEHACKS to no success.

I really don't know where else to turn, as I've literally tried everything at this point and about ready to sell all the equipment I bought. Very depressing. Thanks for any help you can offer

Hmm... The MC7455-CP is a modem out of a Cradlepoint LP6 modem and/or router.

It has a special software package and TAC number, but otherwise it is fully programmable and may be flashed with the Sierra Wireless generic firmware--just like an OEM MC7455.

The other user you referenced was experiencing a slightly different issue.

It is always possible the modem is defective, but it is hard to say without testing it. Did you ever contact the seller?

If you want to reach out to us on the store (using the contact form), we will see if we can help get you up and running.

Hi Jim thanks for responding.

Here are my ATI results in the HT:

Code: Select all

Recieve: ATI
Recieve: Manufacturer: Sierra Wireless, Incorporated
Recieve: Model: MC7455
Recieve: Revision: SWI9X30C_02.20.03.00 r6691 CARMD-EV-FRMWR2 2016/06/30 10:54:05
Recieve: MEID: ----- omitted
Recieve: IMEI: ----- omitted
Recieve: IMEI SV:  6
Recieve: FSN: ----- omitted
Recieve: +GCAP: +CGSM
Recieve: OK
I cannot for the life of me get the modem to reflash to the generic firmware. I feel like once I can get past that hurdle, the rest should fall into place. As mentioned, I followed the Tool Kit, and a few other posts that I found with a similar issue. When I run the installer, it starts to go, then I run into the error "The connection for the USB device 'Sierra Wireless MC7455-CP' was unsuccessful. Driver Error."

What happens when you plug the modem and adapter into the PC and run the Sierra Wireless software drivers for Windows?

It will install the drivers fine, and during it will say that COM was installed successfully as well. I then do the reset commands, reboot, and try to install the generic firmware go to check ATI and it is still showing an old 2016 firmware:

Code: Select all

Recieve: ATI
Recieve: Manufacturer: Sierra Wireless, Incorporated
Recieve: Model: MC7455
Recieve: Revision: SWI9X30C_02.20.03.00 r6691 CARMD-EV-FRMWR2 2016/06/30 10:54:05
Also, this is my result when trying to install the generic firmware. It states I still have some Verizon version on there, despite doing several resets and reboots (after each command). I have internet connection connected and the usb device definitely does work

When you say you have internet connected, are you allowing Windows to manage the Modem and connect to the internet?
