cell phones are hard for the repairs… usually the manufacturer sells batches of parts to repair centers, that do the insurance claims, or just repairs for users. I used to be Ericsson Repair Rep in Europe a while ago.
Other way to do it ... just get a new phone and swap the lcd’s, get the new broken one and send it for service. They will of course charge you but after they are done you can sell it… hassle but ... works.
