• Go to "Service tests" or "Configuration" to find reset options.

4. Using PC and Sony software (if available)

• Use the software’s repair/repair phone or software repair feature which can reinstall firmware and return device to factory state (this also erases user data).

Troubleshooting tips

• If hardware-button method doesn’t show recovery, try Volume Up + Power, or Volume Up + Volume Down + Power.
• Ensure battery has sufficient charge (>50%) before attempting reset.
• If stuck in a boot loop after reset, try wiping cache partition from recovery before rebooting.
