Crucial Warning: This package is specifically built for the Hotwav Venus X14 hardware revision B1_A5. While it shares the same board revision code as the Venus X15, do not cross-flash packages between X14 and X15 models due to distinct battery fuel gauge configurations and LCD panel controller differences. Always install verified Spreadtrum USB drivers prior to flashing.

Frequently Asked Questions
No. Even though both models share the 64_4_B1_A5 board revision code and were compiled on August 13, 2016, cross-flashing is not recommended. The Venus X14 uses a different battery fuel gauge calibration tailored to its 2050mAh capacity (compared to 3000mAh on the X15) and loads distinct LCD panel driver timings in u-boot.bin. Flashing X15 software on an X14 can cause inaccurate battery readings or inverted touchscreen coordinates.
The timestamp signifies that this official firmware build was compiled by Hotwav software engineers on August 13, 2016 at 13:43 UTC. It represents the factory baseline release for the dual-SIM B1_A5 hardware revision.
The "64_4" designation represents a 64Gb (8GB) eMMC flash memory module paired with a 4Gb (512MB to 1GB addressable) LPDDR2 RAM IC. On Android 5.1 Lollipop, system processes require approximately 320MB of working memory, leaving the remaining RAM for user applications.
The Spreadtrum SC7731 chipset integrates a Dual-SIM Dual Standby (DSDS) baseband controller connected to a single transceiver. The modem calibration parameters stored inside the PAC package map SIM1 for 3G WCDMA / 2G GSM connectivity and SIM2 for 2G GSM voice and messaging.
