this is how I did it:
1. Command: AT!ENTERCND="A710"
2. here I want to which image is the modem using: Command: AT!IMPREF?
Code: Select all
AT!IMPREF?
!IMPREF:
preferred fw version: 01.08.04.00
preferred carrier name: SIERRA
preferred config name: SIERRA_002.001_000
current fw version: 01.08.04.00
current carrier name: SIERRA
current config name: SIERRA_002.001_000
OK
3. Now I want to know which images are available. Command: AT!IMAGE?
Code: Select all
AT!IMAGE?

4. Command: at!impref="VERIZON"
5. Command: at!reset
