Stuck in Low Power Mode - Image Preference Mismatch


#1

Hi everyone,

I’m having some trouble with my WP8548 device. No matter what I do, I cannot get it to come out of Low Power Mode, which it enters immediately upon booting.

I believe it has something to do with how I installed Legato, as running the AT!PCINFO? command gives me the following output:

State: LowPowerMode
LPM force flags - W_DISABLE:0, User:0, Temp:0, Volt:0, BIOS:0, GOBIIM:1
W_DISABLE: 0
Poweroff mode: 0
LPM Persistent: 0

In particular, the “GOBIIM” flag is set which, according to the AT Command Reference, indicates an “image preference mismatch.” I’m not exactly sure what that means, although my immediate guess would be it has something to do with how I installed Legato (or flashed the firmware).

I cannot seem to find any information regarding this anywhere on the Web. I greatly appreciate any advice. Thank you much in advance.

I had a similar issue. Let me know if this helps: http://forum.mangoh.io/t/wp7603-shutdown-loop/908/12

Hi,

Can you show the following AT command response?

AT!entercnd="A710"
AT!gobiimpref?

Maybe there is PRI configuration mismatched.
How about going back to the previous FW (using one-click .exe file in Windows) which is working before?

drewwestrick & jyijyi,

Thanks to your suggestions, I was able to fix the issue! I ended up resetting the user partition via swiflash (swiflash -m “WP85XX” -r) and reflashing the firmware with the Generic carrier “SWI9X15Y_07.12.09.00” Release 14 package (via the Windows EXE) from this page:
https://source.sierrawireless.com/resources/legato/wpfirmwarerelease/

Prior to reflashing, the following output was observed via AT!gobiimpref?:

preferred fw version:    07.12.09.00
preferred carrier name:  GENERIC
preferred config name:   GENERIC_001.033_000
current fw version:      07.12.09.00
current carrier name:    NONE
current config name:     NONE_000.000_000

carrier name mismatch
config name mismatch

After flashing, the output is now:

preferred fw version:    07.12.09.00
preferred carrier name:  GENERIC
preferred config name:   GENERIC_001.033_000
current fw version:      07.12.09.00
current carrier name:    GENERIC
current config name:     GENERIC_001.033_000

Furthermore, the command at!pcinfo? now displays its state as “Online” instead of “LowPowerMode.” It’s quite strange, I can’t imagine what I might have done to cause this. However, I’m glad it’s now fixed.

Thank you both very much for your assistance!

Hi,
I have the same issue on WP7502 but firmware reflashing doesn´t help. I tried flashing of combined images FW13.1 and FW14. I tried both ways: flashing from windows (EXE utility) and from native linux (swiflash utility).
Name of preferred carrier/config name is changing but current carrier/config name is still NONE.

!IMPREF:
preferred fw version: 07.11.22.00
preferred carrier name: GENERIC
preferred config name: GENERIC_001.032_000
current fw version: 07.11.22.00
current carrier name: NONE
current config name: NONE_000.000_000

carrier name mismatch
config name mismatch

OK

This issue has started after I erased user partition (restore root file system) by recovery wizard in Developer Studio.

Have you please any suggestion?
Thanks.

Follow the below steps hope it will help:
at!gobiimpref?
!GOBIIMPREF:
preferred fw version: 07.11.22.00
preferred carrier name: GENERIC
preferred config name: GENERIC_001.032_000
current fw version: 07.11.22.00
current carrier name: NONE
current config name: NONE_000.000_000
OK

carrier name mismatch
config name mismatch

at!unlock="A710"
OK

at!gobiimpref=“07.11.22.00”,“GENERIC”,"GENERIC_001.032_000"
OK

at!reset
OK

Command:
at!gobiimpref=“current fw version”,“GENERIC”,“current config name”

It should be Online Now !

Thnx

I don’t know what else to do. I have done everything I’ve read on this post, but I cannot start radio. I think my problem starte when I upgraded form 16.10.1 to 16.10.3 but i’m not pretty sure.
I have read almost all AT command document, I have tried lots of combinations, different SIMs, modules…etc. I also downgraded to 16.10.1. Any suggestions??

Unfortunately, it doesn’t work. I has tried suggested commands and it seems that my WP7502 uses other set of commands. Command at!unlock=“A710” is unknown and at!gobiimpref= works only with one parameter “GENERIC”. You can see this in log. What else can I try?
