Make sure you have installed all your USB drivers for the Samsung Nexus S to connect it with the computer. Download Samsung Nexus S USB drivers! Apart from just the USB drivers, there are a few more things that you need to take care of.

1. You need to enable USB debugging mode. This helps to connect your Android phone with the PC. See here: How to Enable USB Debugging.

2. Your phone battery should be 80-85% charged. If your phone goes off suddenly because of battery, during flashing ROMs or installing mods and updates — your phone might go dead permanently. See here: How to Check Battery Percentage.

3. Backup all your important data that you might need as soon as your flash a new ROM, or make a backup for just in case, you never know when anything might go wrong. See below on how to backup data:

4. Your phone should be factory unlocked. Additional instructions for locked Android devices will be added in the tutorial for unlocking devices.

    hi :) thanks a lot for this guide. is the most easy-to-use one, but i’ve met a couple of problems anyway.
    1. when i go to android-sdk-windows folder i find two folders, one named platforms and the other one tools. Should i create the platforms-tool folder anyway? if i don’t have to, where should i put fastboot and clockwork recovery?
    2. actually, i tried the entire process putting fastboot and clockwork into the folder platforms. i gave the command but i only receive this message “” and nothin more happens.
    Can somebody help me please :)
    Ps: i’m italian, so please forgive my bad usage of the english language :)

    when i type in the command and press enter, a window pops up saying “The program cant start because AdbWinApi.dll is missing from your computer. Try reinstalling the program to fix this problem”. But I checked and that file isnt missing, and even took the liberty of downloading it from elsewhere and replacing it and still no luck. I even tried reinstalling the program and it still won’t work. help?
