Forgot the unlock pattern in Android?

Security and Protection is really important these days and that’s why Android devices provide us with some great security options to keep your device and personal data safe from others who use our device without our permission. We use different screen lock methods like pattern lock, password or pin. Today I’m going to talk about only Pattern lock and how to hack the unlock pattern in Android device if you forgot it.

There could be several reasons that you may forget the lock pattern in your smartphone. Specially if you try to use the lock pattern after a long time. To help us in such a type of a problem, a XDA Developers member m.sabra has provided us a way to hack the unlock pattern of an Android device.

In this tutorial I’ll try to show you how to crack screen unlock pattern on an android device.

Warnings:

We are not responsible for any damage to your device. Do it on your own risk.
We are not responsible if anyone using this method for hacking your device.
This method is for educational purpose only. This method may work for some devices and may not for others.

Precautions:

Keep the Back Up of all your personal data to avoid any loss.
Charge your device before you start the process.

Requirements:

Your Android device should be USB Debugging enabled.
For devices running on latest Android versions, you can find the “USB Debugging” option in Settings>Developer Options.
For devices running on old Android versions, you can find the “USB Debugging” option in Settings>Applications>Development.
It’s good if your device is rooted (you can follow this guide to root an android device). But this method can also work on devices which are not rooted.
ADB installed Windows Computer: Install Android SDK from here. ADB will install along with it.
USB cable of your device.

Instructions:

First of all, connect your device with your Computer using USB cable.
Now click on start and write “cmd” in the search bar. You’ll find a “cmd.exe” file. Open it, the Command Prompt window will appear.
Now type the following commands in the Command Prompt window. Press “Enter” after every line. (Note: After you type the first line and enter it, the Command Prompt window should display “#” instead of “$”. If you’re seeing “$”, then type “su” to switch to the root user.)
adb shell
cd /data/data/com.android.providers.settings/databases
sqlite3 settings.db
update system set value=0 where name=’lock_pattern_autolock';
update system set value=0 where name=’lockscreen.lockedoutpermanently';
.quit
Now you’re device will reboot.
Enter the following command in the Command Prompt and press enter:
adb shell rm /data/system/gesture.key
You’re device will reboot again.
After the complete reboot, your device will display the pattern lock screen. Enter any pattern and you’re device will be unlocked.
Now after unlocking the device, make sure to go to security settings and change the pattern lock.

That’s it. It was easy. So from now on, you don’t have to panic when you forget the screen unlock pattern. The members of XDA Developers always bring something really needy and helpful for us to make our life a little easier.

Guide to Unlock Bootloader of HTC EVO 4G LTE

June 25, 2013 By Satwant Singh Leave a Comment

Many users often unlock the Bootloaders of their Smartphones to install custom ROMs or to root their device. It’s been about two years ago when HTC’s CEO Pete Chou confirmed that the company will not lock the bootloaders of their devices any more. But since then, it’s only HTC One Developer Edition which has an unlocked bootloader.

So we still have to unlock the bootloaders of other HTC devices. In this guide we are talking about the HTC EVO 4G LTE. I’ll explain the instructions briefly that how we can unlock the bootloader of not only HTC EVO 4 G LTE, but other HTC Smartphones too. We’ll be using the method provided by the company.

Warnings:

Unlocking the bootloader may void the warranty of the Smartphone
This guide is suitable for only HTC EVO 4G LTE and for some other HTC devices too. Don’t try this guide for devices of other manufacturers.
We are not responsible for any damage to your device. Do it at your own risk.

Precautions:

Keep the Back Up of all your data as unlocking the bootloader will reset your device to factory settings.
Charge your device before you start the unlocking process.
Reset Google Wallet if you have an NFC equipped device, it’s to prevent the risk of bricking of your device.

Requirements:

Windows running Computer System.
HTC Sync: Download for Windows here.
Android SDK: Download it from here.
Java

Instructions:

First Half:

Go to HTCdev website and register there.
After complete registration, Log in and click on “Unlock Bootloader” and then on “Get Started”.
Now you’ll be directed to a page where you’ll be asked to select the device you want to unlock. Click on the “Select Your Device” dropdown menu, but you’ll not find the “HTC EVO 4G LTE” in the list. So select the “All Other Supported Models” (you’ll find it at the end of the list). Now click on “Begin Unlock Bootloader”.
You’ll see a window asking you to confirm that you surely want to unlock the bootloader of your device. Click on “YES”.
Now, in order to continue you’ll have to accept the two Legal Terms. Check the both boxes and then click on “Proceed to Unlock Instructions”.

Second Half:

As the HTC EVO 4g LTE has a non-removable battery, you’ll have to restart your device by long pressing the “Power Key” and then selecting the “Restart”. Now while the device restarting, hold down the “Volume Down” button to start the device in Bootloader mode.
Now use the “Volume Buttons” to move the Highlight to the “FASTBOOT” and then press the “Power Button”.
Connect your device to the Computer via a USB Cable.
Now run the “SDK Manager” which is an “.exe” file. You can find it from: C Drive>Program Files>Android>android-sdk-windows.
You’ll see a window with number of packages for you to update. You need to install “Android SDK Platform” Tools and “Android SDK Tools”.
After complete installation, find the following files and copy them to a new folder i.e. “C:\Android-sdk”.
– “adb.exe” and “AdbWinApi.dll”. You can find these file from: C Drive>Program Files>Android>android-sdk-windows>platform-tools.
– “fastboot.exe”. Find this file from: C Drive>Program Files>Android>android-sdk-windows>tools.
[Note: In latest Windows Android Tools release, the “fastboot.exe” file could be unavailable. In such case, extract the file from pervious release here.]
Now go to “Start” and write “cmd” in the search bar.
You’ll find “cmd.exe” file. Open it; the “Command Prompt” window will appear.
Now navigate to the folder you just created by typing “cd c:\Android-sdk” in the Command Prompt.
Now type “fastboot oem get_identifier_token” in the Command Prompt and press Enter.
You’ll see some text. Now Right Click on the Command Prompt window and select “Mark”. Now highlight the text as shown below in the picture. (Starting from “<<<< Identifier cut following message >>>>” and ending to “<<<<< Identifier Token End >>>>>”. Don’t highlight the text on the right side of every line. It could be “INFO” or “”.)
Now again Right Click on the Title Bar, go to “Edit” and click on “Copy”. The text you just copied is called “Token”.
Go to HTCdev website, at the Bottom of the third page of instructions of Unlocking Bootloader you’ll find “My Device Identifier Token:” field. Paste the “Token” in that field and click on “Submit”.
You’ll receive an Email containing the Unclock Code Binary File (a “.bin” file). Download it.
Put the downloaded file in the SDk directory.
Type “fastboot flash unlocktoken Unlock_code.bin” in the Command Prompt.
Now you’ll see a disclaimer, just accept it and your device will be Unlocked.

I hope this guide to unlock bootloader of HTC EVO will be helpful. In case of any problem, comment below.

June 24, 2013 By Satwant Singh Leave a Comment

Do you own any older Android device running on Froyo or Gingerbread? So it’s better to have at least Ice Cream Sandwich in this era of Jelly Bean. I’m not saying that you can change the operating system to Ice Cream Sandwich, but you can change the looks of your operating system. Yes, I am going to tell you how to make older Gingerbread or Froyo android devices look like Ice Cream Sandwich, without rooting.

What I’m talking about is “Holo Launcher” made by a senior member mobint at XDA-Developer. This Launcher is a simple, powerful, fast and highly customizable home replacement launcher. This launcher neither needs a rooted device to run nor consume much battery. It also uses very low memory of your device. The average rating of Holo Launcher at Google Play Store is 4.6 with 17,878 “5 star” ratings out of 23,793 which itself is a proof of its popularity.

It works smoothly on devices with operating system of Android 2.2 or above. You can download it from .

Holo launcher covers most of the features (in looks) of ICS.

Infinite Scrolling:

From Desktop Settings in Launcher Settings, you can check box the “Infinite Scrolling” option. You can also choose the “Elastic Scrolling”. The other options like Transition effects, Scrolling speed, Wallpaper scrolling etc. are also there.

Gestures:

Swipe up/down on desktop to launch apps quickly. Go to Launcher settings>Gestures and Keys. There you can change the settings for Swipe up/downs gestures and also some other settings like Home Key action, Home key to default screen and Long press menu key.

Apply icon packs, Support ADW icon pack and Launcherpro icon pack:

Just long hold any icon and then drag it over the icon you want to pack it with.

Desktop Previews:

Pinch to access desktop previews.

Backup and Restore:

Backup and Restore your settings and shortcuts.

Other customizable options:

So overall this launcher is amazing and makes Gingerbread look like Ice Cream Sandwich. If you buy the “Holo Launcher Plus” from you can add more features to this launcher. The Plus Features are listed below:

Unlimited configurable drawer tabs
Unread count notifications for call, sms, gmail and K-9 mail
Customizable notifications badge color
More desktop gestures:

Battery Saver 2X: Life Saver for Android Devices

June 21, 2013 By Arshdeep Singh 1 Comment

Do you own an Android based smartphone? If yes, then you might have faced low battery issues too. Low battery life is an issue with any smartphone be it Android, iPhone or Windows. You can get better battery life in smartphone by following some best practices. Apart from those best practices, there are some apps available that could help you save battery on your Android device. One such application is developed by and I think it is the Viagra for a low battery life.

Features:

This application has tonnes of feature which makes it best in it’s category. This application saves battery life, even optimize applications, set notification alarms, Battery charge notifications, gives you the ability to customise settings and also helps to easy uninstall useless ones.

Battery:When you first open the application you will see a Battery tab here you will see the amount of juice left in the device in terms of cool pool also below it tell us remaining time for which Droid remains active for various activities such as Talktime, Game, Standby ,Audio Playback, Movie Playback, Web Surfing and Reading even you can increase/ decrease the things to appear by clicking on settings icon.

Alert:Now we go to Alert tab here you can set notification Alarm sound on/off. Even application gives you battery charge notification for certain levels such as 100, 70 and 50%. You even have the ability to set notification for low battery so that you can stop other processes to save the life. This feature is pretty cool as user gets to know when it’s device is drinking the juice.

Optimize: This Battery Saver provides you with built-in Optimizer/ Task Manager so no need to download any extra application which is kind of creative thinking as it saves space and processes of CPU because need of installing extra application eliminates. Whenever you feel your device is slow just hit the optimize button and it begins it’s magic.

Setting: This tab is simply as short setting panel we find in our device from here one can switch on/off Wi-Fi, Bluetooth, Auto-sync, Auto-rotation, GPS, Cellular Network, change Screen Timeout and even adjust Screen brightness but we find it pretty useless as one find these options in settings of device too.

Uninstaller: Last Tab of the application acts as easy application manager so when you feel your device is running out of space or it is jaggy then you can uninstall the selected number of useless application in one go.

Appearance and Layout:

We feel that overall appearance and layout of application is decent and serves it’s purpose. It has small five tabs at bottom and cool layout of particular screen running over it. background colour gives it a shiny look and text colour too doesn’t hurt the eyes. Also there is no complexity in navigating from one tab to another.

Value:

So here we come to the most important step value. So Is it worth to download? Since the application is offered for free and is of merely 5.86 MB also it serves it’s purpose fully we don’t see any reason to ignore it. It does saves the juice of your Droid as for example when I installed the application last night battery of device was at 76% and in the morning when I rechecked after 8 hours of sleep device was at 75% whereas earlier drop was used to be by 3-5% so it does save battery life thus saving your time and money. The thing we didn’t liked is the lots of Ads, we know it’s the way of earning by developers but they can offer a paid version too which is free of ads.

Keeping in mind it’s purpose, features offered and appearance we give it 4.5 stars. Download this application from Play Store from

So did you installed this application too and how many stars you give to this app? Do tell us in comments below.
