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.

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/](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.

at!reset
OK
Command:

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?

Hi,
Updating the complete package will update the PRI and modem will be online.
But if level 3 unlock is mandatory, maybe better to ask the Sierra Sales/FAE to generate it.
Thanks.

Hi,
thanks for suggestion. But it is still the same.
I have flashed Firmware package release 15. Current carrier PRI is still NONE. Response to AT commands is similar like it was before flash. See log bellow.
Link to suggested Jenkins job doesn’t work for me. Do You thing that level 3 unlock could help?

Hi all, I think there’s some confusion about the use of !GOBIIMPREF here. In the logs shown above, the current _preference_ is valid, and it’s the current image that’s showing NONE, which is causing the LPM vote. The attempts to use GOBIIMPREF to set the preference, as shown above, would only set the preference to the same value it’s already set to, rather than actually changing the current version.
There are a few reasons the system can be in this state. The main one is that an image switch to the preferred image is prevented if the preferred configuration (combination of FW, carrier, and carrier config version) is not present on the system. When you load an official release package, that should guarantee that the configuration is available. Evidently that isn’t happening. The following command is not officially published, but I’m going to put in a request to add this to external documentation. It requires Level 2 unlock (AT!ENTERCND=“A710”):
On my system:
at!image?
TYPE SLOT STATUS LRU FAILURES UNIQUE\_ID BUILD\_ID
FW 1 EMPTY 0 0 0
FW 2 EMPTY 0 0 0
FW 3 EMPTY 0 0 0
Max FW images: 2
Active FW image is at slot 255
```
TYPE SLOT STATUS LRU FAILURES UNIQUE_ID BUILD_ID
PRI FF GOOD 0 0 0 001.034_000 07.12.14.00_GENERIC
Max PRI images: 50
OK
```
I am not using slots for Modem images, at the moment, so mine are empty. And the only carrier configuration I have loaded is the Generic as shown. You can use this command to check if the configuration in your preference is actually available. Can you provide the output from that command? A few other general health checks that might help diagnose: AT!PRIID? AT!PACKAGE?. These will confirm that the main configuration components are still valid. If this doesn’t help, I realize this is an older thread, but I wonder if you can pinpoint what upgrade path or action triggered this issue, to help debug further.

This is the history of the problem:
This modem was bought with WPFirmwareRelease13.1 and radio worked fine.
This issue started after flashing procedure failure. The aim was upgrade to WPFirmwareRelease14 but windows flashing utility has frozen during flashing process. I restarted the modem but it got stuck at boot sequence and continuously restarted. I did recovery process and cleared user partition. Then I flashed WPFirmwareRelease14 successfully. But there is “Image Preference Mismatch” since this time.
Also an issue with GPIO settings revealed. Nearly all of them were under modem control. I switched them under user space control. So GPIO issue is solved. But “Image Preference Mismatch” persists.
Thank you for your assistance.

A small update after investigating @liborsvehla’s device off-thread: we found that the customization “GOBIIMEN” was disabled on his device, which prevented the modem from applying the image preference, resulting in the device becoming stuck in LPM. I provided a small SPK file that “patched” his configuration for that item, which recovered normal operation.
If anyone else observes the same issue (confirmed by “GOBIIMEN” not shown in the AT!CUSTOM? response), please feel free to post or contact me directly for assistance.
Thanks @liborsvehla for taking the time to debug this.

Hello @rkirk,
It seems that I encountered the same problem as @liborsvehla with a device stuck in LPM.
The GOBIMEN flag is not listed in the AT!CUSTOM? response.

What can I do to recover my device ?
Thanks.

Hi @babare, thanks for raising this. Your symptom of having the customization “GOBIIMEN” disabled matches the previous occurrence, and I’ll message you directly with a tool attached for restoring that.
@liborsvehla described a firmware download issue just prior to this problem. Did you also observe any firmware download failure, or an unexpected power cycle during an upgrade/downgrade?
Thanks,
Ryan

@rkirk, I am also experiencing an LPM, but I don’t have a mismatch. I am using a WP7601-1 device and was programming it when the came about. I don’t have GOBIMEN in AT!CUSTOM either. I can only talk to it via the AT Command port.

Hi @EvetsMostel, the GOBIIMEN customization was added to the earlier generations (wp8548, wp75xx) because the features it gated were introduced during that products life cycle. The WP7601-1 had a more concrete starting point with respect to that feature, and so the customization was not introduced - the feature is always enabled. Can you also provide AT!PCINFO?, to show the cause of the LPM? AT!PRIID? may also help.

@rkirk,
at!pcinfo?
State: Low Power Mode
LPM voters - Temp:0, Volt:0, User:1, W\_DISABLE:0, IMSWITCH:0, BIOS:0, LWM2M:0, OMADM:0, FOTA:0
LPM persistence - User:1
I’m assuming it’s the last one? It currently has Verizon’s Release 8 on it (from Sierra), or at least that’s what I tried to install to get it back.

Thanks @EvetsMostel, yes it’s the “User” field, in this case, which is supposed to mean that you (or a SW application as user) actually requested LPM. As I assume this is not the case :), I suspect this is related to a resolved issue in Release 9, listed in release notes as QTI9X07-1009, with the following description: “In rare cases it has been reported that after entering LPM with AT+CFUN=0 that the module was unable to return online with AT+CFUN=1 despite having no other reason to prevent it. This state is now removed.”
Since we haven’t released a carrier certified Verizon image as part of Release 9, this makes things less convenient. But you can resolve this issue with a short but awkward workaround:
AT!ENTERCND=“A710” // enable level 2 access
AT!CUSTOM=“CFUNPERSISTEN”,01 // Enable Persistent LPM
Reset
AT!ENTERCND=“A710”
AT+CFUN=1
AT!CUSTOM=“CFUNPERSISTEN”,00 // Assuming you want the customization disabled
Or you can leave the customization enabled, if it’s something you’d rather keep enabled. Let me know if that doesn’t get you out of your LPM state.
