Developers fought back with patched DA (Download Agent) files, Auth Bypass tricks, and tools like UnlockTool or CM2 that now require paid credits. The free, glorious era of clicking one button to restore an IMEI is fading — replaced by subscription-based professional boxes (Easy JTAG, Z3X, Medusa Pro).
