Hi, Azad, thank you for your comment, according to the video, yes, there's a baseband problem showing by the round perspective, we have checked the original video materials, and confirmed it's an edit error by our video editor who unintentionaly edited the previous troubleshooting scene into the later system restoration scene. Thank you again for your comment, we will definitely be more careful when we editing and hopefully will share more inspiring repair videos and tutorials.
