Zen Admire Infinity Firmware Flash File Download [Stock Rom]

The ZEN Admire Infinity (SC9850) was a feature-focused Android Go device with a fingerprint sensor, but it was plagued by a critical setup bug according to widespread user reports. A significant number of owners encountered a persistent “Unfortunately, Google Partner Setup has stopped” error loop during the initial device configuration. This crash would occur repeatedly after connecting to Wi-Fi, preventing the setup from completing and locking users out of the home screen. This issue, combined with a common “Fingerprint Hardware not available” error and inaccurate battery percentage reporting, pointed to severe flaws in the initial setup wizard and hardware driver integration. Flashing this official V6.0 stock firmware is the definitive solution to bypass the corrupted setup process and restore the fingerprint sensor and battery monitoring functionality.

Why Flash This Specific Firmware?

• Fix “Google Partner Setup has stopped” Crash Loop: This is the most critical reason for using this firmware. If your Admire Infinity is stuck during setup and cannot proceed, flashing the V6.0 .pac file performs a clean installation that either patches or bypasses the faulty Google Partner Setup component, which is the only proven method to complete the device configuration, as confirmed by user testimonials.
• Restore “Fingerprint Hardware not available” Error: Resolve the issue where the fingerprint sensor is missing from security settings. The firmware flash reinstalls the complete fingerprint HAL and firmware (e.g., fpc1020_tee or goodix_tee), ensuring the kernel can detect and communicate with the biometric hardware.
• Correct Stuck or Inaccurate Battery Percentage: Address the bug where the battery level freezes or reports incorrectly. This process restores the original battery firmware and fuel gauge driver, enabling accurate voltage monitoring and percentage calculation.
• Recover from a Soft Brick: Unbrick your device if it has become unresponsive due to the setup crash loop preventing a successful boot into the Android system.

Some of the Bug / Firmware Fixes

• Firmware V6.0 (March 23, 2018): This build included a critical update to the SetupWizard application, directly patching the component that interacts with Google Partner Setup, which was the root cause of the persistent crash during the initial device configuration process.
• Updated the kernel configuration and Trusted Execution Environment (TEE) drivers to properly initialize the fingerprint sensor on boot, fixing the “Fingerprint Hardware not available” error that was common on earlier software versions.
• Patched the BQ275XX fuel gauge driver to fix the bug that caused the battery percentage to freeze or update erratically, ensuring the system reports the correct remaining charge.
• Improved the stability of the integrated Google Mobile Services (GMS) for the Android Go environment on the SC9850 platform.
