How to Unlock and Flash Infinix X557 (X557-H807A1D1): Fix Privacy Protection Lock and Other Issues

Infinix Hot 4 X557 16+2 A1 PRIVACY CODE

If your Infinix X557 (Hot 4 Pro) is stuck with the error "Your Phone Is Protected, Please Enter Privacy Protection to Unlock", or facing issues like hanging on the logo, viruses, or requiring a software upgrade, this detailed guide will help you unlock and flash your phone step by step.

What Causes the Privacy Protection Lock Issue?

This error typically occurs when the phone has been factory reset without properly removing the linked account or anti-theft features. Wiping EMMC (data partition) from the recovery menu will not resolve the issue in such cases. Instead, a full flash is required.

1. Using SP Flash Tool with the “Full Format” option.
2. Using Miracle Box (or its crack) to clear the anti-theft lock.
