The Zopo Color S5.5 C5510BS M arrived in mid-2016, making its mark as a large-screen budget Android for the Indian and Southeast Asian markets. Buyers of this exact hardware revision reported persistent Wi-Fi disconnects, ghost touch problems and random shutdowns within months of device use—complaints much more frequent in C5510BS M than in earlier Color S5.5 variants. Repair forums also noted that failed OTA updates triggered consistent bootloops and even rare complete loss of IMEI, especially after unintentional “Firmware Upgrade” flashes using SP Flash Tool. This official August 16, 2016 build is the only version calibrated for the C5510BS M modem and panel batch, restoring stable Wi-Fi/Bluetooth pairing, touchscreen responsiveness and all original network bands specific to Asian retail models.

Why Flash This Specific Firmware?
- Restore Original Wi-Fi and Bluetooth Performance: Indian buyers described “Wi-Fi won’t reconnect” and “Bluetooth drops headset every 2–10 min”—this build flashes hardware-matched radio firmware for the C5510BS M’s IC batch, instantly fixing pairing and range.
- Repair Touchscreen Random Taps (Ghost Touch) and Dead Zones: Only the region-specific firmware includes the correct panel vendor driver for Asian hardware; global files cause slow or erratic touch, especially lower screen third.
- Recover SIM and IMEI After Catastrophic “Firmware Upgrade” Flash: C5510BS M had more IMEI wipe cases than any S5.5; this package restores both NVRAM and network calibration critical for Jio/Vodafone/Airtel bands.
- Fix Bootloop and Power Loss After Update Failure: Users who applied over-the-air builds or flashed with wrong files frequently got stuck at boot logo—official build re-partitions /boot and /recovery for guaranteed startup.
How to Flash the Firmware
Use SP Flash Tool:
- Extract firmware and launch SP Flash Tool. Click Scatter-loading, select MT6735M scatter file.
- Select “Download Only” mode (not “Firmware Upgrade”) to save IMEI/SIM data.
- Click Download, connect powered-off phone via USB. Wait ~12 minutes for progress. Green checkmark means finished.
- Reboot and test Wi-Fi, SIM, touch.
