Boot Modifiers
From Android Wiki
Keys to hold while pressing power
- menu -> safe mode
- home -> recovery utility
- camera - > bootloader mode (Bootloader)
- trackball -> radio interface
- home+back -> factory reset - a different method to do the same thing as alt+w in recovery mode
Recovery Commands
These commands are for the 'Recovery mode' screen - i.e. when you see the graphic of the exclamation point and a phone
- Alt+L - toggle logging to the screen (this also prints out a menu of options)
- Alt+S - apply update on sdcard (update.zip)
- Alt+W - factory reset (wipe all data)
- return -> boot loader information screen
Redundant information is at G1 keyboard and button shortcuts
