Factory Images for Nexus Devices 安裝步驟

範例機種：Nexus 5X (bullhead)

範例版本：6.0.1 (MMB29Q)

事前準備

fastboot oem unlock
adb/bootloader/recovery驅動安裝
- MTP → Android Composite ADB Interface
- fastboot (bootloader) → Android Bootloader Interface
- Recovery Mode → Android Composite ADB Interface
- adb sideload → Android Platform Sooner Single ADB Interface
驅動測試
- 開始狀態，輸入adb devices
- Bootloader mode，輸入fastboot devices
- TWRP Sideload，輸入adb devices
Factory Images 檔案
SuperSU (需要root才要)
twrp-x.x.x.x-bullhead.img (需要Custom Recovery才要)

開始

找到 6.0.1 (MMB29Q)
點擊 Link，下載檔案 bullhead-mmb29q-factory-197bd207.tgz

解壓縮至此，資料夾結構如下

 bullhead-mmb29q
     ├─bootloader-bullhead-bhz10k.img
     ├─flash-all.bat
     ├─flash-all.sh
     ├─flash-base.sh
     ├─image-bullhead-mmb29q.zip
     └─radio-bullhead-m8994f-2.6.30.0.68.img

進入Bootloader模式

開機狀態，輸入 adb reboot bootloader
關機狀態，使用 Vol Down + Power

以下分成自動、手動刷入

自動刷入

執行 flash-all.bat 即可
註：如需保留個人資料請修改flash-all.bat部份內容，如下

將 -w 刪除
fastboot -w update image-bullhead-mmb29q.zip

手動刷入

將 image-bullhead-mmb29q.zip 解壓縮至此，資料夾結構如下

 bullhead-mmb29q    
     ├─android-info.txt
     ├─boot.img
     ├─bootloader-bullhead-bhz10k.img
     ├─cache.img
     ├─flash-all.bat
     ├─flash-all.sh
     ├─flash-base.sh
     ├─image-bullhead-mmb29q.zip
     ├─radio-bullhead-m8994f-2.6.30.0.68.img
     ├─recovery.img
     ├─system.img
     ├─userdata.img
     └─vendor.img

依序鍵入以下指令
1. fastboot flash bootloader bootloader-bullhead-bhz10k.img
2. fastboot reboot-bootloader
3. fastboot flash radio radio-bullhead-m8994f-2.6.31.1.09.img
4. fastboot reboot-bootloader
5. fastboot flash boot boot.img
6. fastboot erase cache
7. fastboot flash cache cache.img
8. fastboot flash recovery recovery.img
9. fastboot flash system system.img
10. fastboot flash vendor vendor.img
Note: 如需保留原有TWRP Recovery，請跳過步驟8

刷入TWRP Recovery

進入Bootloader模式

開機狀態，輸入 adb reboot bootloader
關機狀態，使用 Vol Down + Power
fastboot flash recovery twrp-3.0.2-2-bullhead.img

刷入SuperSU

進入TWRP Recovery
- 開機狀態，輸入 adb reboot recovery
- 關機狀態 1. 使用 Vol Down + Power 2. 使用 音量鍵 選擇 Recovery mode，並按下 電源鈕 確認

以下分為兩種方法

方法1

將 BETA-SuperSU-v2.67-20160121175247.zip，放置手機內部記憶卡

清除 Dalvik-Cache 和 Cache

選擇 Install

選擇 BETA-SuperSU-v2.67-20160121175247.zip

方法2

與電腦連接

選擇 Advanced → ADB Sideload

勾選 Wipe DalvikCache 和 Wipe Cache

Swipe to start Sideload

電腦cmd，輸入 adb sideload BETA-SuperSU-v2.67-20160121175247.zip

Nexus 5X 初見面

1. 安裝驅動程式

adb devices
fastboot devices

2. Unlock Bootloader

開啟開發者人員選項
設定 → 系統 → 開發者人員選項
OEM 解鎖 → 開啟
USB Debugging → 開啟
adb shell
允許USB偵錯 → 確定
adb reboot bootloader
fastboot oem unlock
選Yes Unlock bootloader (may void warranty)
在Bootloader畫面中，會顯示DEVICE STATE - unlocked為紅字

3. 刷入TWRP

adb reboot bootloader
fastboot flash recovery twrp-3.0.2-2-bullhead.img

4. 解除資料加密

※ 使用者資料將全部重置 ※

刷入[FIX] FED-Patcher v8 (ForceEncrypt Disable Patcher)
adb reboot bootloader
fastboot format userdata
fastboot reboot

5. 備份EFS

adb reboot recovery
選擇 Backup
只勾選 EFS
Swipe to Backup
在TWRP裡，將備份好的EFS，匯入電腦端，adb pull /sdcard/TWRP TWRP
將TWRP資料夾備份至雲端空間

6. Root

將BETA-SuperSU-v2.67-20160121175247.zip，放置於手機內部記憶卡
adb reboot recovery
選擇 Install
選取 BETA-SuperSU-v2.67-20160121175247.zip
Wipe Cache/Dalvik
