EM7565 stuck in factory mode

Hello,

During a long night, I executed AT commands on my EM7565 to make some tests. The initial config was the following:

ATI
Manufacturer: Sierra Wireless, Incorporated
Model: EM7565
Revision: SWI9X50C_01.08.04.00 dbb5d0 jenkins 2018/08/21 21:40:11
IMEI: <redacted>
IMEI SV:  8
FSN: <redacted>
+GCAP: +CGSM

To revert my changes, I performed an AT!RMARESET=0 instead of an AT!RMARESET=1 (late at night…). Since that, the card IMEI changed and I can’t see the provision image in RMARESET anymore…

ATI
Manufacturer: Sierra Wireless, Incorporated
Model: EM7565
Revision: SWI9X50C_01.08.04.00 dbb5d0 jenkins 2018/08/21 21:40:11
IMEI: 001027009999999
IMEI SV:  8
FSN: <redacted>
+GCAP: +CGSM,+DS,+ES


AT!RMARESET?
!RMARESET:
0 Factory


OK

Do you know can I rollback to the SKU image?

Best regards,
zapok

Hi zapok,

First, please download and try to reflash your firmware at the link below:

If the issue is not resolved, try AT!RMARESET=1

Thanks,

Hi @jerdung!

Reflashed my firmware and nothing changed…
When I tried to execute AT!RMARESET=1, returned me an error, as before:

AT!RMARESET=1
!RMARESET: DEVICE REBOOT REQUIRED

Items Restored:  0
Items Deleted:   0
Items Defaulted: 0

ERROR

Any idea? :confused:

Many thanks for your help!

Hi zapok,

If you remember your old IMEI, you can follow the doc below on pages 38 & 39 to write your IMEI to the module. You may find your old IMEI on AirVantage if your device successfully registered to it.

https://source.sierrawireless.com/resources/airprime/minicard/75xx/41111748-airprime-em75xx-at-command-reference/#sthash.H7Ydknyq.dpbs

If not, the only thing you can do is to return your device to distributor for help.

Thanks,

Hello @jerdung,

Many thanks for this documentation!
I could restore the IMEI with some additional searches on the specified AT command!
