Update old firmware on EM7565

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?

Ah, thanks to another post I just found sierra-wireless-modems/Sierra-Linux-QMI-SDK.md at master · danielewood/sierra-wireless-modems · GitHub
Will try that now.
