Hello, please attach a photo or video (it will be better) where the display of the phone can be clearly visible. Maybe the phone is unlocked and needs to check some details (as in the logs SIM State: LOADED), but for that, it is necessary to see the phone.

Upload the video to your favorite file-sharing platform and paste the link here.
