Root + Helper zip + LSPosed scope. Phir profile se Android ID / IMEI / Ad-ID.
1. Root and Helper
Use Magisk or KernelSU. Install the official Helper zip first, then reboot. Skip this and the APK can crash.
2. APK and LSPosed
Install Mirage Spoofer v21.39. Enable the module, tick each target app — steps on LSPosed and Xposed module.
3. Profiles, not one global ID
Create or bulk-create profiles. Each can carry Android ID, IMEI-style fields, Ad-ID, model. Switch from Home or the widget. Force-stop the target app after a switch. Full page: device ID changer.
4. Compared with Geergit / Mantle
If you came from those names, read Geergit alternative, Mantle alternative, and the compare table. Mirage is a separate official product.
