步驟

1.所需工具：adb.exe 與fastboot.exe
Android SDK (Android Studio https://developer.android.com/studio/index.html#downloads)
下載後安裝，需手動增加Android SDK Tools (https://developer.android.com/studio/intro/update.html)
File > Settings >  Preferences >  Appearance & Behavior > System Settings > Updates

File > Settings >  Preferences >  Appearance & Behavior > System Settings > Android SDK > SDK Tools Tab
or
Tools > Android > SDK Manager > SDK Tools Tab

增加Android SDK Platform-tools
更新後在Local PC..\Users\User\AppData\Local\Android\sdk\platform-tools
資料夾內可以找到adb.exe 與fastboot.exe

2.下載原廠ROM
"razor" for Nexus 7 [2013] (Wi-Fi) 6.0.1 (MOB30X)

3.重新安裝 Nexus 7 [2013] Image的步驟
3.1.Nexus7開啟USB Debug Mode (關於平板電腦 > 版本號碼連續按7下可以開啟開發人員選項)
3.2.連接上Local PC，會自動抓driver，Nexus 7 上跳出message box，詢問是否授權USB debug mode，建立USB debug mode連線。
3.3.在Local PC上開啟cmd.exe，執行adb.exe
3.4.指令
$adb devices (查看手機裝置是否有順利連接)
$adb kill-server (關掉 adb 伺服器)
-->如果有多餘的虛擬連線，要先砍掉，不然會跳出error message
$adb reboot bootloader (Nexus 7重新開機後進入fastboot mode)
3.5.fastboot mode的操作
unlock/lock：$fastboot oem unlock/lock (Nexus 7 [2013]是舊型號)
3.6.在原廠ROM裡面已經有flash-all script，執行即開始更新Image
3.7."flash-all.bat" for windows
