after I deleted the file /var/lock/LCK…ttyAMA0, i was able to open minicom.
But there is no response on keyboard. Even CTRL A , Z, E did not help

I turned off LTE->auto connection under gateway-config and everything worked, but
after a crash the interface is always locked…

You can refer to the documentation to complete the operation, which states that you must ensure that LTE connecting is disable.
