LG N4 進入Recovery 模式後，出現紅色驚嘆號

也許你是被逼無奈必須要root一下你的手機，也許你像我一樣是一個苦逼的程式員，為了調試bug而root這個裝置。不管何種原因，root完畢後，開啟系統始終停留在一個X介面，或者google的開機閃屏視窗。而進入 Recovery模式下後，小機器人被幹倒了，胸部出現了一個紅色驚嘆號的圖片。。。，表慌，表心裡暗罵了十遍以上神馬刷機精靈，一鍵root等坑爹。。。。。，其實我也突然心裡有點慌了一下。。。

如果以上串連打不開，就參考以下：

Factory Reset using physical buttons

1.	Power off your phone.

2.	Press and hold Volume Down, and then press the Power button until the device turns on (while still pressing Volume Down). You will see the word Start with an arrow drawn around it.

3.	Press Volume Down twice to designate Recovery mode.

4.	Press the Power button to restart into Recovery mode. You will see an image of an Android robot with a red exclamation mark.

5.	While holding down the Power button, press and release Volume Up.

6.	Use the volume keys to scroll to wipe data/factory reset and press the Power button to select it.

7.	Scroll down to Yes - erase all user data and press the Power button to select it. Your device will reset to factory settings.

Note:

If at any point during the above steps your phone becomes unresponsive, you can restart it by holding down the Power button for several seconds.
