See if this helps > [@EM7565 Can't upgrade FW](https://forum.sierrawireless.com/t/em7565-cant-upgrade-fw/27550/5): > > From this link: [https://source.sierrawireless.com/-/media/support\_downloads/airprime/75xx/fw/7511/build5183/9999999\_9907259\_swi9x50c\_01,-d-,14,-d-,02,-d-,00\_00\_generic\_002,-d-,035\_003.ashx](https://source.sierrawireless.com/-/media/support_downloads/airprime/75xx/fw/7511/build5183/9999999_9907259_swi9x50c_01,-d-,14,-d-,02,-d-,00_00_generic_002,-d-,035_003.ashx) ([https://source.sierrawireless.com/resources/airprime/minicard/75xx/em\_mc75xx-approved-fw-packages/#sthash.qa3UwPX4.dpbs](https://source.sierrawireless.com/resources/airprime/minicard/75xx/em_mc75xx-approved-fw-packages/#sthash.qa3UwPX4.dpbs)) Just make it online mode again with at!impref command Just download lastest FDT and lastest FW for modem, no luck: FDT version: 2.0.2012.0 Awaiting suitable port or adapter ... Switching… I also wonder if AVMS upgrade can help You can also have a look on this one which says it needs intermediate firmware for very old firmware > [@Update old firmware on EM7565](https://forum.sierrawireless.com/t/update-old-firmware-on-em7565/27184): > > Greetings, we have some EM7565 modules which are still on the very old firmware SWI9X50C\_01.00.02.00 (6ff48a jenkins 2017/09/29 05:54:26) and would like to update them due to some issues. However, in the release notes it is said that this requires to flash a specific firmware version first (release 9, if I understand correctly). Where can I find this specific firmware version? --- _[View the full topic](https://forum.sierrawireless.com/t/em7565-9-segmentation-fault-when-trying-to-flash-firmware/35880)._
