## Overview

This repository provides a no-serial-change iOS activation server in two forms: PHP web endpoints and a local C# server. The main workflow fetches a live Apple activation seed, then uses that seed and device details to build a signed activation record for reactivation. In PHP, the endpoints delegate shared validation, rate limiting, Apple communication, and record-building logic to common.php. The README documents the equivalent local-server workflow; sampled C# excerpts show its listener, request handling, seed fetch, and record construction. Some C# routing details are not shown.

Main entry points: [`sn.php`](https://github.com/bunnyciaa/mg-unlooker-server-code/blob/main/sn.php) (Seed endpoint), [`nosn-nochange.php`](https://github.com/bunnyciaa/mg-unlooker-server-code/blob/main/nosn-nochange.php) (Record endpoint), [`common.php`](https://github.com/bunnyciaa/mg-unlooker-server-code/blob/main/common.php) (Apple seed fetch), [`NoSnServer.cs`](https://github.com/bunnyciaa/mg-unlooker-server-code/blob/main/NoSnServer.cs) (Local HTTP server)
