several ways of ROOTING Android device by Yourself

The most basic and important step during any type of development on android is, ROOTING it..

SO here are some ways so that u can root your device:-

Rooting Android with z4root :-

First, you’ll need to make sure that non-Market app installs are allowed; this is called sideloading apps. To do this, go to Menu > Settings > Applications and check “Unknown Sources”. (If it’s greyed out, that means that your carrier has decided to be mean and block sideloading. To remove this restriction, try rooting with SuperOneClick or device-specific rooting below.)

Now that your phone allows sideloading, download z4root onto your phone. Once it has been downloaded, use a file manager to navigate to the APK installer (it will probably be in the download folder) and install z4root. After it is installed, launch z4root from your app tray open it up from your launcher:

 Once z4root has been launched, you are half-way finished. Now all you have to do is decide if you want a permanent root, or just a root until you reboot your phone (temporary root). If you want a permanent root, be aware that it won’t work on every phone (try SuperOneClick or device-specific rooting if z4root doesn’t work for you).
Once you select what type of root you want, just follow on-screen instructions and you will be rooted within minutes. You know you are rooted if you have a “SuperUser” app in your app tray. You may have to reboot your device for this to appear. If the “SuperUser” app appears, congrats! Your Android 2.2 phone is now rooted.
Te following is the list of known phones compatible/incompatible with the permanent root:

If your phone is not in the list shown above, it may or may not be compatible with z4root. The only way to find out is try it out. If your phone is on the incompatible list, you can only use the temporary root option.

Rooting with SuperOneClick :-

Rooting with SuperOneClick is a fairly easy affair, but requires a bit of setup first. The first thing you need to do is make sure your device will work with SuperOneClick. It is most likely compatible if it is not one of these (the following are incompatible devices)

• Sprint EVO 4G (HTC Supersonic)
• Droid Incredible (HTC Incredible)
• HTC Desire GSM
• HTC Desire CDMA (HTC BravoC)
• HTC Aria
• Droid Eris (HTC DesireC)
• HTC Wildfire (HTC Buzz)

These phones have locked NAND chips. In order to remove this lock, you must use unrevoked, a NAND unlocker.
So far the known phones that are compatible with SuperOneClick are:

• Acer Liquid Metal
• Dell Streak
• HTC Magic (Sapphire) 32B
• HTC Bee
• LG Ally
• Motorola Atrix 4G
• Motorola Charm
• Motorola Cliq
• Motorola Droid
• Motorola Flipside
• Motorola Flipout
• Motorola Milestone
• Nexus One
• Samsung Captivate
• Samsung Galaxy 551 (GT-I5510)
• Samsung Galaxy Portal/Spica I5700
• Samsung Galaxy S 4G
• Samsung Galaxy S I9000
• Samsung Galaxy S SCH-I500
• Samsung Galaxy Tab
• Samsung Transform M920
• Samsung Vibrant
• Sony Ericsson Xperia E51i X8
• Sony Ericsson Xperia X10
• Sprint Hero
• Telus Fascinate
• Toshiba Folio 100

The key thing to note is just because your phone is not on the above list does not mean SuperOneClick won’t work with your phone. As long as your phone is not listed on the incompatible list (first list shown above), then your phone may still work with SuperOneClick. The only way you will know for sure is to give it a try; if you are on Android 2.3 Gingerbread or lower, SuperOneClick will likely work for your device. Use other method if ur device isnt compatible.
After verifying your phone is rootable, there still remain couple of prerequisites to rooting your device:

• You NEED to put your phone on USB Debugging mode
• You NEED to install make sure the Android drivers for your phone are installed
• Make sure you DO NOT mount your SD card
• If you still can’t get something to run, try doing it in recovery mode

To put your device into USB Debugging mode, go to Settings > Applications > Development and check the “USB Debugging” box. After enabling debugging, install drivers for your phone on your computer and plug in your phone.
After installing the drivers, you’ll need to download SuperOneClick. Note that, due to the exploit used in the rooting program, it may be detected as a virus; this is to be expected and the program is clean as far as we know.Open SuperOneClick.exe (Vista + 7: right click -> run as administrator):

The beauty of SuperOneClick is its rooting method is universal, allowing for all Android devices to be rooted at any version number. So, just hit Root to root your device.
(Sidenote: After rooting, if your device did not allow for sideloading, you can enable sideloading on your device by hitting the Allow Non-Market Apps buttons.)
Once the root procedure has finished, go back to your device. Open your app launcher and you should a new app called “Superuser”. This verifies your device has been rooted; if you don’t see it, try rebooting your device.

Other :-

If z4root nor SuperOneClick worked for your device and we haven’t covered your device , the best place to find how to root your device is XDA-Developers. Visit XDA and look for your specific device; then roam the forums and look for a thread that explains how to root. (You will most likely find it in the Android Development subforum for your device.) You can even ask questions if you have trouble.
