iPhone是初代iPhone（中国又称iPhone 2G）。型号为 A1203，存储容量有4GB、8GB、16GB可选，机身颜色仅有黑色搭配金属铝。维修初代iPhone是容易的，需要耐心，其他工具和焊接。
As far as I know, you will have to install iTunes on your computer and restore the firmware of the device with iTunes. It should be noted that you will lose all data on the iPhone if you use this procedure.
1. Plug your iPhone into computer with iTunes installed, and open.
2. Shut down the iPhone (hold power button and slide to power off)
3. With the iPhone off, hold the power button for three seconds
4. While holding the power button, press and hold the home button at the same time.
5. Hold both buttons for 10 seconds.
6. Let go of the power button, but continue holding the home button.
After roughly 8-10 seconds, you should see a prompt in iTunes telling you that the connected device is in recovery mode and needs to be restored. From there, follow the prompts to download the iOS firmware for your device and restore it to factory defaults.
