Hello All,
Just to inform where current BIOS release 1.42 was modified in order to remove BIOS white-lists. As I had mentioned earlier, by using this method MC7304 was able to be installed and running fine and able to access internet with full 4G LTE. I would like to install MC7455 as well and had followed all steps as mentioned earlier but still no luck.
About all related drivers are downloaded from “sierra source” website and don’t have any ideas how to enable MC7455 be recognized on X220T.
Regards,
Zainul
