I recently upgraded some EM7565 modules from version 01.07.02.00_genetic to 01.14.02.00_generic due to some cellular instability issues. The FW upgrade worked and the connectivity has improved but now the GNSS does not synch with satellites after the update on some of the modules not all of them. I am looking for a way to downgrade the FW the previous version to run some tests. The question is, how do I downgrade (rollback) to the previous FW version stored as an image of the module?
Hi Julio.Sanchez,
Welcome you to our community.
You can register your EM7565 on Airvantage (https://eu.airvantage.net/) and downgrade to the previous FW version via Airvantage.
Thank you for your reply, I have tried to connect to the Airvantage server but always get a +wdsi: 7.
I have registered the modem on the site and have cellular connection with the SIM.
These are the commands I’m using:
at+wdsi=4095
OK
at+wdss=0, “media.ng”
OK
at+wdss?
+WDSS: 0,“media.ng”
+WDSS: 1,0
ok
at+wdss=1,1
ok
+wdsi: 7
Hi Julio Sanchez,
Please share the output of the following commands:
ATI3
AT!GSTATUS?
AT!IMPREF?
AT!IMAGE?
AT+WDSG
Hi Julio.Sanchez,
You can download the 01.07.02.00_generic EM7565 firmware to your PC. You then can downgrade the firmware for EM7565.
Thank you for your help.
