how to unlock screen lock on i phone x

You cannot unlock an iPhone using Chromebook.

You need a Mac or Windows, read here => If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support

Hello, thanks for using Apple Support Communities.

For security reasons, the only way to unlock an iPhone is to enter its passcode.

Another option would be to erase the device and restore your data from a backup, however I don't think iTunes is compatible with Chromebooks.
