The Mobicel Venus G is a budget smartphone with a Spreadtrum/Unisoc SP7731C chipset and Android 8.1. Like many SPD-based devices, it is vulnerable to persistent bootloop (stuck at logo), dead/no power after incomplete flashing, malware and pop-ups, rapid battery drain, IMEI/network or Wi-Fi failure, and Google FRP lock after resets.
When these serious issues occur, the best solution is a full firmware reinstallation using the official PAC file and SPD Upgrade Tool.

- Fix Bootloops/Logo Stuck: This ROM repairs Mobicel Venus G phones that keep restarting or hang on the Mobicel logo after updates, malware, or factory resets.

- Remove Malware, Restore Battery, and IMEI: System-level malware, pop-ups, or network and battery issues that survive resets are wiped only by factory ROM flashing.
- Fix No Network/Wi-Fi/Camera: Lost IMEI, Wi-Fi, or camera failure is often caused by corrupted OS and is fixed only by official firmware.
- Bypass FRP/Google Account Lock: A fresh ROM flash resets the device, bypassing any lingering Google locks or frozen/frp-locked recovery after reset.
