Hi all. I just recently purchased an EM7565 from a friend to upgrade from my EM7455. Running an AT!IMAGE?, it shows that there's a newer firmware version installed in slot 1, but I can't for the life of me figure out how to switch over to that firmware.

Code: Select all

AT!IMAGE?
TYPE SLOT STATUS LRU FAILURES UNIQUE_ID   BUILD_ID
FW   1    GOOD   2   0 0      ?_?         01.08.04.00_?
FW   2    GOOD   3   0 0      ?_?         01.07.02.00_?
FW   3    EMPTY  0   0 0                  
FW   4    EMPTY  0   0 0                  
Max FW images: 4
Active FW image is at slot 2

TYPE SLOT STATUS LRU FAILURES UNIQUE_ID   BUILD_ID
PRI  FF   GOOD   0   0 0      002.008_004 01.07.02.00_ATT
PRI  FF   GOOD   0   0 0      002.004_001 01.07.02.00_GENERIC
Max PRI images: 50


OK

Could someone give me some guidance on how to switch that firmware over to the newer version? Thanks!

Type in AT!IMPREF=1 for slot 1 I believe. Dbl check that though, there are tutorials here for the Sierra cards.

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?
TYPE SLOT STATUS LRU FAILURES UNIQUE_ID   BUILD_ID
FW   1    GOOD   130 0 0      ?_?         01.08.04.00_?
FW   2    GOOD   129 0 0      ?_?         01.07.02.00_?
FW   3    GOOD   1   0 0      ?_?         01.09.04.00_?
FW   4    GOOD   127 0 0      ?_?         01.11.00.00_?
Max FW images: 4
Active FW image is at slot 1

TYPE SLOT STATUS LRU FAILURES UNIQUE_ID   BUILD_ID
PRI  FF   GOOD   0   0 0      002.008_004 01.07.02.00_ATT
PRI  FF   GOOD   0   0 0      002.015_000 01.09.04.00_DOCOMO
PRI  FF   GOOD   0   0 0      002.004_001 01.07.02.00_GENERIC
PRI  FF   GOOD   0   0 0      002.001_000 01.08.04.00_SIERRA
PRI  FF   GOOD   0   0 0      002.017_000 01.09.04.00_SOFTBANK
PRI  FF   GOOD   0   0 0      000.001_001 01.08.04.00_SPRINT
PRI  FF   GOOD   0   0 0      001.000_000 01.07.02.00_TELUS
PRI  FF   GOOD   0   0 0      002.015_001 01.08.04.00_VERIZON
Max PRI images: 50


OK

From here if I wanto to use Verizon then I type in at!impref="VERIZON"

4. Command: at!impref="VERIZON"

Code: Select all

at!impref="VERIZON"
OK

5. Command: at!reset

Code: Select all

at!reset
OK

6. if everything went smooth as it should, you can confirm which image your modem is using the command posted on step 2.

use this tutorial at your own risk.
