Understanding "SPD IMEI Write" Tools, "Hassan Zip" Files, and Mobile Repair Risks What is SPD (Spreadtrum/Unisoc)? SPD refers to chipsets manufactured by Spreadtrum Communications , now part of Unisoc . These SoCs (System on Chips) are found in budget Android phones, feature phones, and some IoT devices. Brands like Itel, Tecno, Infinix, Lava, and many low-cost Chinese phones use SPD chips. What Does "IMEI Write" Mean? Every mobile phone has a unique International Mobile Equipment Identity (IMEI) number – typically 15 digits. This number is stored in a secure partition (e.g., NVRAM, EEPROM, or the modem’s firmware). If this partition gets corrupted (common after failed flashing, wrong firmware, or software glitches), the phone may show "Invalid IMEI," "Null IMEI," or no network service.
