How to do a hard and soft reset with G1

SOFT RESET

1) Turn Off the Phone
2) Remove Battery
3) Remove Sim Card
4) Put battery and sim card again
5) Turn On the phone
6) Press Menu
7) Factory Data Reset (Remember that: This action will reset the phone to its initial factory state, erasing all data and wonloaded applications, so BACKUP BACKUP BACKUP first you try this).
Press "reset phone"


HARD RESET
1) Turn off the Phone
2) Press HOME + POWER KEYS (keep them holding for about 25 secs)
until you see a screen with a phone and a triangle.

then

3) SLIDE YOUR KEYBOARD TO OPEN IT
4) press ALT + l ( TO SHOW YOU OPTIONS)
5) Press ALT + W ( TO FORMAT ALL DATA)


Note: When I write the sign + you don't have to press the + sign, it means that you need to press both keys @ the same time.

Note2: Don't do this if you don't have a Data Plan or your 2G or 3G is not working, why? because you will not be able to sign in again without a working Data Plan (2g / 3g).
