MC7455 Carrier Name Mismatch Config Name Mismatch

Having issues with an MC7455 getting updated. I can only seem to get the older generic image to work on it.

Every time I flash the newer AT&T and Verizon images to the card and prefer those carriers I get the carrier name and config mismatch errors.

OK

If i change AT!IMPREF=“GENERIC” it works fine using an AT&T M2M SIM card on m2m.com.attz however when I change to AT!IMPREF=“VERIZON” it updates the preferred and the current fw version however current carrier name and current config name does not change and the card goes into low power mode.

What am I missing?

Hi Matthew,
You can only switch carrier if the firmware releases are the same for GENERIC and VERIZON.
For Verizon, you are using fw 2.33 but Generic is 2.24, so there will be the mismatch when you switch carrier.
Please upgrade the GENERIC to 2.33
The firmware is as below:
https://source.sierrawireless.com/resources/airprime/minicard/74xx/airprime-em_mc74xx-approved-fw-packages/#sthash.Ygdnwsbc.dpbs

And one more, after change carrier, please reboot the device.

Thanks,

Hi Matthew,
What is the output of “AT!IMAGE?” command?
I’m not sure what is the root cause, but you can set the image manually to fix the mismatch
AT!IMPREF =“fw version”[,[“carrier name”,]“config name”]

Ex:
AT!UNLOCK=“A710”
AT!IMPREF=“02.33.03.00”,“GENERIC”,“GENERIC_002.072_000”

And then reboot device, hope it can fix your issue.

Thanks,

@matthew.george

So note for the above, you won’t be able to do the at!unlock conmmand it will need to be at!entercnd=“A710”.

Regards

Matt

AT!ENTERCND="A710"

jerdung · September 23, 2020, 12:54am

Hi Matthew,
As I mentioned above, UNLOCK command is required for setting firmware with IMPREF command

Example:

 at!impref="02.28.03.03","GENERIC","GENERIC_002.068_000"
 
 ERROR
 AT!ENTERCND="A710"
 
 OK
 at!impref="02.28.03.03","GENERIC","GENERIC_002.068_000"
 
 ERROR
 at!unlock="A710"
 
 OK
 at!impref="02.28.03.03","GENERIC","GENERIC_002.068_000"
 
 OK

Thanks,

AT!UNLOCK does not work

The card only accepts AT!ENTERCND=“A710”

Even after doing that the following command throws an error;

Hi Matthew,
Oh, I’m sorry, It is my mistake, your device could not use UNLOCK command.
Could you please try to change to VERIZON image and then back to GENERIC?
Please help to try these commands, and send us the output:
AT!IMPREF=“VERIZON”
AT!RESET
AT!IMAGE?
AT!IMPREF?
AT!IMPREF=“GENERIC”
AT!RESET
AT!IMAGE?
AT!IMPREF?

Thanks,

matthew.george · September 23, 2020, 8:13pm

Again none of these commands are making a difference. I cannot get the “Current Config Name:” name to change and as a result the card enters low power mode and will not activate.

I have noticed several other people are having the exact same issue on this forum.

I have requested a refund from the seller of this card as I’m unable to get this card to function.

In the mean time i’m going to try an older firmware to see if it changes.

When upgrading the firmware in these cards is there an upgrade path that must be followed?

Matthew,

I am having the same problem after downloading the lastest Verizon firmware.
I have a “Rev B” modem that works fine. And the “Rev A” modem produces:

at!impref?
!IMPREF:
preferred fw version: 02.33.03.00
preferred carrier name: VERIZON
preferred config name: VERIZON_002.079_001
preferred subpri index: 000
current fw version: 02.33.03.00
current carrier name: GENERIC
current config name: GENERIC_002.026_000
current subpri index: 000

carrier name mismatch
config name mismatch

OK

I know this doesn’t help you, but I’m also working on finding a solution.
