The Zopo Speed 8 (MediaTek Helio X20 MT6797) launched in mid-2016 as one of the world’s first deca-core smartphones, equipped with 4GB RAM, a 5.5-inch Full HD display, and a powerful 21.5 MP Sony camera. Despite the flagship performance on paper, communities on XDA and multiple Android review sources report a recurring battery drain, fingerprint reader malfunction, and network instability under Android 6.0, with sudden standby losses of up to 70% overnight, poor Wi-Fi/Bluetooth range, and fingerprint unlock errors—even after re-registering prints. Flashing this official firmware resolves critical system partition corruption, restores proper hardware drivers, and re-calibrates all key components.

Why Flash This Specific Firmware?
- Fixes Critical Battery Drain: Verified by user threads, the Zopo Speed 8 may lose over 70% battery overnight even in Airplane Mode due to bugs in the Android fingerprint service and runaway systemd-logind processes. The stock image prevents this by restoring correct system power management and fingerprint driver interaction.
- Restores Working Fingerprint Sensor: Many Speed 8 (MT6797) units display “fingerprint not recognized” or fail to add new prints after updates. This firmware reinstalls the required HAL and cryptographic dependencies, verified to restore success for fresh registration.
- Solves 4G/Wi-Fi/Bluetooth Network Drops: Known Helio X20 bugs include sudden LTE call drops during network handover, Wi-Fi NVRAM (0x10) errors, and weak Bluetooth range. Factory firmware re-flashes modem/NVRAM and network stack for reliable data, voice, and wireless connections.
- Prevents Overheating/Random Shutdown: Early device batches suffered random reboots and thermal shutdown when multitasking or charging—often triggered by improper CPU core management on Helio X20. The stock image restores factory thermal profiles.
Crucial Prerequisites Before Flashing
- Backup All Data: This process will wipe user storage, apps, photos, and messages.
- Charge to 60%+: Avoid power loss during firmware flashing.
- Install MTK USB Drivers: MediaTek USB VCOM drivers are required for detection in SP Flash Tool.
