Instructions for setting up Adb/Fastboot (windows)

1. On your phone go to Settings/Development and make sure USB debugging is ON and plug it in via the usb..  New phones go the settings about phone then click on the build number 10 times then back out to settings again and you will see developer options right above about phone. click on developer options then select usb debugging from there. also known as adb debugging.

2. Install drivers on your PC. Try pda.net for the drivers. Install the program by hitting “Run” and follow the instructions. You can remove it at a later time.

3. Download the file at the bottom of these instructions to your desktop and extract the contents. There is 1 folder and a install note (these instructions) that should extract. You can use a program called 7-ZIP to extract if needed (google it, its free and a great tool).

4. Open your “Start” menu and click on “My Computer”. Then choose “Local Disk C:”.(You can now click and drag the adb folder you extracted to the C: drive.

5.Open a command prompt and type cd\adb and hit enter. You should now see something that looks like this C:\adb>

6.Type adb devices then hit enter in the command prompt and it should list your device.

7. You can also type adb reboot bootloader which will put the device into bootloader mode. Now type fastboot devices then hit enter in the command prompt an it should list your device. (you must be in the bootloader for fastboot to recognize your device)

Screen shot of commands

You should now be ready to send commands to your phone via ADB or Fastboot. You will need to repeat steps 5-6 anytime you want to use ADB/Fastboot. To send a file using Adb or fastboot make sure to put the file in your “adb” folder before giving the command to send it to your device.

How to unlock your bootloader on the Nexus device using ADB/FASTBOOT
1.  Open a commandline window in your ADB folder by holding shift and right clicking mouse.
2.  Type adb devices then hit enter in the command prompt and it should list your device.
3.  Type adb reboot bootloader hit enter
4.  Type fastboot oem unlock hit enter
5,  Your tablet will then ask if you want to unlock.  Using the volume keys, highlight “Yes” and then press the power button to select it. Your bootloader will now be unlocked.  Choose to start your tablet and it will factory reset itself and reboot. You are now operating with an unlocked Nexus.
6.  Now that your nexus is unlocked you need to flash a recovery to it in ADB.
7.  Open a commandline window in your ADB folder by holding shift and right clicking mouse.
8.  Type adb devices then hit enter in the command prompt and it should list your device.
9.  Type adb reboot bootloader hit enter
10.  Type fastboot flash recovery (name of recovery.img) then hit enter. Make sure you put the recovery .IMG in the ADB folder on your computer.  I recommend twrp recovery.
 WHAT IS A LOGCAT

Logcat is the command to view the internal logs of the Android system. Viewing logs is often the best way to diagnose a problem, and is required for many issues. This way you’ll find out what apps are doing in the background without you noticing.

TAKING AN LOGCAT

Now type this in the terminal
adb devices (note) to make sure devices is connected
adb logcat -v long > logcat.txt
OR

adb logcat > logcat.txt:

you shall have a log file called name of problem.txt inside your ADB folder.  Now open the logcat.txt file and see whats your problem.

Here are some commands for Adb/Fastboot.
DO NOT USE ANY COMMANDS THAT YOU ARENT SURE OF OR DONT KNOW WHAT THEY DO. I AM NOT RESPONSABLE FOR ANYTHING THAT YOU DO TO YOUR PHONE.

  2. I am grateful you are here to help, however, I was trying to continue the article on adb and fastboot commands but it ended with the note, want to read the rest click a button below and share, upon doing that and sharing on google+ the article remained at the same location with nothing more.
    thank you

  3. you should update your article. The ‘pda.net’ plug is close to nonexistent, so invalid at this point. You also shouldn’t just leave readers with one site to use.. it would be nice if you actually took time to do more researching.
