Hi everyone! I hope you are all doing well. I’ve been attempting to add an EM7455B module to the account. However, the synchronization log shows:
Application or firmware returned by this system is unknown from AirVantage [EM7455B,MDM_SWI9X30C_02.33.03.00_PRI_9904609-002.072.000]. This firmware version appears on https://source.sierrawireless.com/resources/airprime/minicard/74xx/airprime-em_mc74xx-approved-fw-packages/
In addition, I’ve tried to run a test OTA update, which returned “The selected firmware is not compatible with the current firmware on the device. Please check the name and type are consistent with the devices firmware ones”. EM7455B GENERIC Release 18 (MDM_SWI9X30C_02.24.03.00_PRI_9904609-002.021.000). It’s clear that the OTA firmware is older than the one installed, but the “not compatible” message is a bit confusing. Is it impossible to downgrade firmware versions via OTA, and is it possible to update the firmware version to the listed “approved firmware”?
