[EM7455] "config name mismatch"

I’m in trouble with EM7455 in my dell laptop. It is still not connectable to mobile network.
I found an error message in the result of the AT command, “at!impref?”
“config name mismatch”
How can I fix this mismatch to correct config name’s version?

 preferred fw version:
 preferred carrier name:  GENERIC
 preferred config name:   GENERIC_002.025_000
 current fw version:
 current carrier name:    GENERIC
 current config name:     GENERIC_001.007_000

 config name mismatch

PRI Part Number: 9904336
Revision: 001.007
Customer: Dell

Carrier PRI: 9999999_9904609_SWI9X30C_02.24.05.06_00_GENERIC_002.025_000


I know that setting prefer carrier command set is at!impref=“carrier name”, and this command is applied well.
But I don’t know how to fix the config name or set prefer config name for matching both prefer & current config names.
How can I fix it?
Please help me. I’m in need your help, friends.
Thanks in advance
