Factory reset T-Mobile G1
How to reset or restore a T-Mobile G1
If your mobile/cell phone T-Mobile G1 works very slow, it hangs, you want to bypass screen lock, or memory is full, and you want to erase everything, or you want to sell it or give it away and you want nobody to be able to access your files and passwords. You can do a factory reset so that it returns to be like the first day.
In the following steps we explain how to format the T-Mobile G1 to erase all your information and make it totally clean as it came out of the store.
Before doing a factory reset, we recommend deleting all the accounts on the device, specifically it is useful to unlink the Google account if you are going to sell, donate, or give away your G1. This will avoid problems for the new user, as some newer devices include a functionality called FRP (Factory Reset Protection) that requires the same Google account or PIN code with which the T-Mobile G1 was initially configured when factory resetting a device.
Keep in mind that a reset or return to the factory state on a mobile/cell phone deletes all its content, so make a backup of your data before doing it if you don't want to lose everything.
In case you do not want to erase the data from the device, you can try to restart the T-Mobile G1..
There are two ways to do a reset on a T-Mobile G1 one through the mobile options and another more complete from the recovery mode.
