Format: Flashable ZIP containing system, kernel, and patches.
Purpose: Install Android 7.1.2 on unsupported or older devices (e.g., Samsung S5, OnePlus One, Xiaomi Redmi Note 3).

Prerequisites (Mandatory)

2. Understanding the ZIP File Types for Android 7.1.2

Not all ZIPs are equal. Before you download, identify which type you need: Prerequisites (Mandatory)

| ZIP Type | File Name Example | Use Case | |----------|------------------|-----------| | Factory Image | angler-n2g48c-factory-xxxx.zip | Full restore, unbricking, or clean install (requires fastboot) | | OTA Update ZIP | 7.1.2_OTA_update.zip | Upgrade from 7.1.1 to 7.1.2 without wiping data (needs adb sideload) | | Custom ROM ZIP | lineage-14.1-20231015-UNOFFICIAL-bullhead.zip | Flash via custom recovery (TWRP) | | GApps ZIP | open_gapps-arm64-7.1.2-pico-20220215.zip | Add Google services after flashing a custom ROM |

Critical warning: Never flash a ZIP intended for a different device model. Cross-flashing (e.g., Nexus 5X ZIP onto a Pixel) will hard-brick the device.

Method 1: Flashing Stock Android 7.1.2 via Fastboot (For Nexus/Pixel/OnePlus)

Download Platform Tools – Get the latest ADB/fastboot package from Google.
Extract the factory zip – Unzip the image-bullhead-nougat.zip (or equivalent) into the same folder as fastboot.exe.
Boot your device into fastboot mode – Power off, then press Volume Down + Power.
Open a command prompt in the platform-tools folder.

Flash each partition manually (clean flash avoids bootloops):

fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img (WARNING: erases internal storage)
fastboot reboot

First boot takes 5–10 minutes. Do not interrupt.
