The Positivo First S410 is an entry-level dual-SIM Android, powered by the Spreadtrum SC7731G platform. It features a 4-inch LCD (480×800), 512MB/1GB RAM, 4GB storage, and runs Android 5.1.1 Lollipop. Over time, users encounter common issues like bootloop (stuck logo), invalid IMEI or baseband, network/SIM errors, app crashes, and devices that won’t power on. These are typically caused by failed OTA or partition corruption and are rapidly fixed by flashing the official SPD PAC firmware below.
This DGUI firmware package is validated to unbrick soft/hard dead S410 units, restore IMEI/network function, erase malware, and return full stock performance. Flash the PAC with SPD Upgrade/Research Tool.
