Single User Mode without root password for maintenance

Original article at :  http://www.noah.org/wiki/Single_User_Mode

This method will get you past the "Give root password for maintenance" message, but the environment will be much more primitive, but this should be enough for you to issue a 'passwd' command to change the password for root. If you want to do more than that then you may have to mount filesystems and manually start the network.

1. Reboot your machine; press 'Esc' to get to the GRUB menu; select your image; press 'e' to edit; select the Kernel line.
2. Press 'e' to edit the kernel line. Edit the line to get rid of quiet and splash; change 'ro' to 'rw'; and add 'init=/bin/bash'. The line should look something like this:

   kernel /vmlinuz-2.6.15-27-386 root=/dev/mapper/Ubuntu-root rw init=/bin/bash

3. Press 'enter' then 'b' to boot with these new settings. 

Update :
For GRUB2, if you don't get the GRUB menu while booting, you need to press "SHIFT" key after BIOS shown up until GRUB menu displayed.
Also to boot after editing the entry, you need to press "CONTROL-X" .

Can’t establish a reliable data connection to the server (solved)

If your Android device says "Can’t establish a reliable data connection to the server" when you about to connect to Google Account, you may check the date and time setting.
Please set the correct date, time and time-zone manually. Your network may not be able to provide the correct date & time.

To do this, on you home screen, click "menu" button, click "setting" menu item, scroll down until you find the "Date and time" menu and click it.
And back to your GMail/Market/Account setting.

At least this method works on my Galaxy S.
