The Hotwav Venus R10, built on the Spreadtrum SC7731C (SP7731CEB), was launched to offer a reliable and affordable full Android experience in African and Asian markets. By late 2017, users in Nigeria, Kenya, Ghana, and India were sharing complaints about network “No SIM” errors, stuck boot logos, random touchscreen freezing, and persistent “System UI has stopped” alerts—especially after failed updates or flashing the wrong SPD firmware. This 6.0 Marshmallow version (build 30062017, 565MB) is the only confirmed .pac file to restore normal dual SIM detection, working camera, stable Play Store, and responsive touch for Venus R10 SP7731CEB hardware. Flashing generic SPD .pacs or R10 firmware from a mismatched date almost always breaks SIM/network, touch, or results in permanent app crash at boot.

Why Flash This Specific Firmware?
- Recover All Dual SIM/Network: Only this build restores the matching NVRAM and APN tables required for instant SIM and 3G/2G carrier detection, a must fix after “No SIM” errors post-update or flash.
- Fix Bootloop and “System UI” Crashes: Devices stuck at logo or seeing persistent system error after a bad update can be rescued—this scatter .pac fully rebuilds /boot, /system, and Google apps for a clean launch every time.
- Eliminate Touchscreen Lag or Dead Panel: Nigerian and Indian users often lost touch (or saw ghost input) after flashing the wrong Venus R10/R7 pd—only this firmware restores exact panel drivers and sensor mapping for 100% input area recovery.
- Repair Camera and LED Flash Problems: Many non-official .pacs left the camera black or unable to save—V10_30062017 brings back main and selfie sensors with native photo/video function.
