The Zen Admire Thrill Plus is an Android 6.0 Marshmallow device built on a Spreadtrum SC9832 chipset, commonly found in budget-friendly segments. A distinct and recurring problem reported by users on technical forums involves the device suddenly losing all network signal, displaying “No Service” or “Emergency Calls Only” despite a functional SIM card. As noted by repair technicians, this issue is frequently tied to corrupted modem firmware (NVRAM), not the hardware itself. Flashing this official V1.3 stock firmware reinstalls the complete system, including the critical modem files, to restore network connectivity and resolve this frustrating error.

Why Flash This Specific Firmware?
- Restore Network Signal (“No Service” Fix): This is the most cited reason in repair communities. The firmware repopulates the NVRAM partition with the correct modem files, fixing the software glitch that causes a complete loss of cellular network.
- Resolve “Ghost Touch” & Screen Glitches: As reported by some users, erratic and unresponsive touchscreen behavior can sometimes be traced to corrupted touch panel calibration data. A full firmware flash resets this calibration to factory defaults.
- Unbrick a Soft-Bricked Device: If your phone is stuck in a bootloop, frozen on the Zen logo, or won’t power on properly, this stock ROM is the essential tool to make the device bootable again.
- Revert from a Custom ROM: Return your device to its original, stable factory state, ensuring full compatibility with the hardware and restoring any vendor-specific features that may be broken in custom ROMs.
Some of the Bug / Firmware Fixes
- Firmware V1.3 (April 27, 2017): This build includes critical patches for the modem software, directly addressing the widespread “No Service” bug that plagued earlier software versions by reinitializing the baseband and IMEI provisioning.
- Reinstalls the stock touchscreen driver and calibration files, resolving phantom touch inputs and unresponsive areas of the screen reported by some users.
- Fixes system instability and random reboots that occurred under load, such as when opening multiple applications, by restoring the original kernel and system libraries.
- Addresses issues with the Wi-Fi and Bluetooth drivers, improving connection stability and range after the flash.
