I've got something strange going on with my device. After a software crash I rebooted but the /opt dir disappeared.

The /home/opt symlink is just gone and when I type ls in the root dir, I still see /opt, but when I do cd opt it says: -sh: cd: can't cd to /opt

More on, when I try to flash the complete eMMC it starts up but then stops with the message : SU_GET_UPDATE_STATUS_REQ terminated with error code 1.

Any help is appreciated!
