The Positivo Twist S511 is an entry-level Android designed for cost-sensitive markets, powered by a Spreadtrum SC7731 quad-core chipset and 1GB RAM. Common user complaints include: stuck on boot logo after factory reset or update, touchscreen not working post-flash, FRP (Google account) lock, slow charging, unstable USB connection, failed recovery mode, and in some cases, total brick from wrong firmware or interrupted flashing. Some S511 devices suffer charging-port/contact problems, adding risk when flashing. Many recoveries require SPD tool and the exact matching firmware, as cross-model flashes often fail.
