Ever wanted to know how to factory reset your T-Mobile G1? Don't worry Android Central has got you covered. Doing a factory reset is a fairly easy process on the G1 and is immensely useful for those returning units, selling units, and/or just want a fresh start.

Here's how it works:

  1. Power off the G1
  2. Hold Home Key + End key for 20 seconds or until you see a "triangle with an exclamation point and a picture of the G1"
  3. Open the QWERTY keyboard and hit Alt+W
  4. Restored!

To do a soft reboot, simply hit the Home+Back buttons when you reach the "triangle with an exclamation point and a picture of the G1" screen.
