G1 Google Phone: Hard Reset

If your T-Mobile G1 Google smartphone is not responding or is frozen, you may have to opt for a hard reset. Here’s how:

1. Turn the G1 off.  If it’s frozen on, take the battery out and put it back in the unit.

2. Hold the Home and Power keys down at same time for about 25 seconds. You will see a yellow triangle screen with exclamation point in the middle.

Now to wipe the device clean:

3. Press Alt+L.

4. Press Alt+W for a factory reset.

5. Press the Home and Back keys again for about 25 seconds.

The device should then reset again and the hard reset is complete.

    @the level of creating google account just press the menu button and select APN names.. there it will give you the list of APN you have but in your own case you dont have any so you’ll need to create meny again and select new APN. This is where you enter the apn and the configurations of your network provider then you go back to account creation stage you should be able to continue.. I just did my own now. Good luck

  11. Randy says

    Liric yea wen u don’t have a data plan on your g1 is only about time before it locks on u so either unlock your g1 or get a data an I don’t meen put your password or code thingy unlock I meen unlock or jailbreak

  12. A. Harris says

    I’d like to clear up some confusion.

    1) This erases your contacts on your phone. Provided you have Contacts sync setup, they will come back down from Google to your phone

    2) This resets the whole phone and you will need to re-sign in to your Google account

    3) This does not format the memory card. To do the memory card, you must do that manually using the SD option in settings. Unmount the card and erase.

    However, this is a great guide to do a hard reset if you are selling the phone.

    Thanks to the original poster for the information. Sometimes it pays just to do a hard reset one time owning the phone so it keeps going fast – its an OS and like every OS on the market, a reset is needed sometimes.

    Thats what I get for using a PDA lol

  32. Smogy says

    I could not do a hard reset with the above advice but the following worked perfectly :)

    Power off the G1
    Hold Home Key + End key for 20 seconds or till you see a triangle with an exclamation point and a picture of the G1

    Open the QWERTY keyboard and hit Alt+W

  33. robert m says

  34. Louise says

    3 day old G1, update notification came up whilst on charger, hit ok, next time I look I have a triangle with an exclamation point and a pic of the phone beneath it.
