Safe mode can help you troubleshoot your Android, but
sometimes you’ll need to wipe everything and restore
your device to its factory state. You can even perform
a factory reset when your Android phone or tablet won’t boot normally.
Ensure you have any important data backed up before doing a reset.
This includes your Google Authenticator credentials, which will be lost
during the reset. Disable two-factor authentication on your accounts
first or you’ll experience some trouble afterwards.
If You Can’t Boot
If safe mode doesn’t help fix your device, you can perform a hard
reset by booting into a special recovery mode. First, ensure your
device is fully shut down.
Press and hold the correct keys to boot the device into recovery mode.
This will vary from device to device. Here are some examples:
Nexus 7: Volume Up + Volume Down + Power
Samsung Galaxy S3: Volume Up + Home + Power
Motorola Droid X: Home + Power
Devices With Camera Buttons: Volume Up + Camera
Similar devices will likely use similar key combinations. For example,
the Nexus 4 also uses Volume Up + Volume Down + Power.
If your device isn’t on this list and none of the above methods work,
do a Google search for the name of your device and “recovery mode”
– or look in the device’s manual or support pages.
Release the buttons when the device powered on.
You’ll see an image of an Android lying on its back
with its chest open and its internals revealed.
Press the Volume Up and Volume Down keys to scroll through the options until you seeRecovery mode on the screen.
Press the Power button to restart into recovery mode. You’ll soon see an Android with a red triangle.
Hold down the Power button and tap Volume Up. You’ll see the Android system recovery menu appear at the top of your screen.
Select wipe data / factory reset with the volume keys and tap the Power button to activate it.
Select Yes – erase all user data with the volume buttons and tap Power. Your device will be reset to its factory state and all your data will be erased.
If your device freezes at any point, hold down the Power button until it restarts.
If You Can Boot
You can reset your Android phone or tablet normally from its Settings screen. Tap theBackup & reset option on the latest versions of Android or tap Privacy if you’re using Android 2.3.
Tap the Factory data reset option and to through the reset of the steps to confirm the factory reset.
If the factory reset process doesn’t fix your problems – or doesn’t work at all – it’s likely that there’s a problem with your device’s hardware. If it’s still under warranty, you should have it fixed or replaced.
(There’s one exception to this: If you’ve been flashing custom ROMs and messing with your device’s low-level software, it’s possible that you could have overwritten the stock recovery software. In this case, it’s possible that you have a software problem and not a hardware problem.)
How to Crack a Wi-Fi Network's WEP Password with BackTrack
You already know that if you want to lock down
your Wi-Fi network, you should opt for WPA encryption
because WEP is easy to crack.
But did you know how easy? Take a look.
Today we're going to run down, step-by-step, how to crack a Wi-Fi network with WEP security turned on. But first, a word: Knowledge is power, but power doesn't mean you should be a jerk, or do anything illegal. Knowing how to pick a lock doesn't make you a thief. Consider this post educational, or a proof-of-concept intellectual exercise.
Dozens of tutorials on how to crack WEP are already all over the internet using this method. Seriously—Google it. This ain't what you'd call "news." But what is surprising is that someone like me, with minimal networking experience, can get this done with free software and a cheap Wi-Fi adapter. Here's how it goes.
What You'll Need
Unless you're a computer security and networking ninja, chances are you don't have all the tools on hand to get this job done. Here's what you'll need:
A compatible wireless adapter—This is the biggest requirement. You'll need a wireless adapter that's capable of packet injection, and chances are the one in your computer is not. After consulting with my friendly neighborhood security expert, I purchased an Alfa AWUS050NH USB adapter, pictured here, and it set me back about $50 on Amazon. Update: Don't do what I did. Get the Alfa AWUS036H, not the US050NH, instead.The guy in this video below is using a $12 model he bought on Ebay (and is even selling his router of choice). There are plenty of resources on getting aircrack-compatible adapters out there.
A nearby WEP-enabled Wi-Fi network. The signal should be strong and ideally people are using it, connecting and disconnecting their devices from it. The more use it gets while you collect the data you need to run your crack, the better your chances of success.
Patience with the command line. This is an ten-step process that requires typing in long, arcane commands and waiting around for your Wi-Fi card to collect data in order to crack the password. Like the doctor said to the short person, be a little patient.
Crack That WEP
To crack WEP, you'll need to launch Konsole, BackTrack's built-in command line. It's right there on the taskbar in the lower left corner, second button to the right. Now, the commands.
First run the following to get a list of your network interfaces:
airmon-ng
The only one I've got there is labeledra0. Yours may be different; take note of the label and write it down. From here on in, substitute it in everywhere a command includes (interface).
Now, run the following four commands. See the output that I got for them in the screenshot below.
If you don't get the same results from these commands as pictured here, most likely your network adapter won't work with this particular crack. If you do, you've successfully "faked" a new MAC address on your network interface, 00:11:22:33:44:55.
Now it's time to pick your network. Run:
airodump-ng (interface)
To see a list of wireless networks around you. When you see the one you want, hit Ctrl+C to stop the list. Highlight the row pertaining to the network of interest, and take note of two things: its BSSID and its channel (in the column labeled CH), as pictured below. Obviously the network you want to crack should have WEP encryption (in the ENC) column, not WPA or anything else.
SEXPAND
Like I said, hit Ctrl+C to stop this listing. (I had to do this once or twice to find the network I was looking for.) Once you've got it, highlight the BSSID and copy it to your clipboard for reuse in the upcoming commands.
Now we're going to watch what's going on with that network you chose and capture that information to a file. Run:
Where (channel) is your network's channel, and (bssid) is the BSSID you just copied to clipboard. You can use the Shift+Insert key combination to paste it into the command. Enter anything descriptive for (file name). I chose "yoyo," which is the network's name I'm cracking.
SEXPAND
You'll get output like what's in the window in the background pictured below. Leave that one be. Open a new Konsole window in the foreground, and enter this command:
aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 -e (essid) (interface)
Here the ESSID is the access point's SSID name, which in my case isyoyo. What you want to get after this command is the reassuring "Association successful" message with that smiley face.
Here we're creating router traffic to capture more throughput faster to speed up our crack. After a few minutes, that front window will start going crazy with read/write packets. (Also, I was unable to surf the web with theyoyonetwork on a separate computer while this was going on.) Here's the part where you might have to grab yourself a cup of coffee or take a walk. Basically you want to wait until enough data has been collected to run your crack. Watch the number in the "#Data" column—you want it to go above 10,000. (Pictured below it's only at 854.)
Depending on the power of your network (mine is inexplicably low at -32 in that screenshot, even though theyoyoAP was in the same room as my adapter), this process could take some time. Wait until that #Data goes over 10k, though—because the crack won't work if it doesn't. In fact, you may need more than 10k, though that seems to be a working threshold for many.
SEXPAND
Once you've collected enough data, it's the moment of truth. Launch a third Konsole window and run the following to crack that data you've collected:
aircrack-ng -b (bssid) (file name-01.cap)
Here the filename should be whatever you entered above for (file name). You can browse to your Home directory to see it; it's the one with .cap as the extension.
If you didn't get enough data, aircrack will fail and tell you to try again with more. If it succeeds, it will look like this:
The WEP key appears next to "KEY FOUND." Drop the colons and enter it to log onto the network.
Problems Along the Way
With this article I set out to prove that cracking WEP is a relatively "easy" process for someone determined and willing to get the hardware and software going. I still think that's true, but unlike the guy in the video below, I had several difficulties along the way. In fact, you'll notice that the last screenshot up there doesn't look like the others—it's because it's not mine. Even though the AP which I was cracking was my own and in the same room as my Alfa, the power reading on the signal was always around -30, and so the data collection was very slow, and BackTrack would consistently crash before it was complete. After about half a dozen attempts (and trying BackTrack on both my Mac and PC, as a live CD and a virtual machine), I still haven't captured enough data for aircrack to decrypt the key.
So while this process is easy in theory, your mileage may vary depending on your hardware, proximity to the AP point, and the way the planets are aligned. Oh yeah, and if you're on deadline—Murphy's Law almost guarantees it won't work if you're on deadline.

If you want to install Windows 8 from a USB device, you'll need to get those setup files onto a USB Pen Drive. Unfortunately, simply copying them there will not work.
Windows 8 is sold as DVD and also as a downloadable ISO file which, if you choose to buy Windows 8 that way, requires some steps to get it properly copied to a flash drive as well.
Boot Windows 8 from USB Pen Drive
Whether you have a Windows 8 DVD or a Windows 8 ISO file with the same goal, the following tutorial will help you get the Windows 8 installation files properly copied to a flash drive so you can get on with the installation process.
Note: The following procedure applies equally to Windows 8 (standard) or Windows 8 Pro.
Duration: Getting the Windows 8 installation files onto a flash drive or other external USB device will take between 20 and 30 minutes, depending on what format your copy of Windows 8 is in right now and how fast your computer is.
Important: If you have a Windows 8 ISO file and want that on a flash drive, start with Step 2. If you have a Windows 8 DVD and need that on the flash drive, start with Step 1
Procedure For Making Windows 8 Bootable:
1. If you already know how to create ISO files with your favorite program then do so in whatever way you're used to doing it or check for any DVD or CD burning Software provided with your DVD Drive or Writer budle and create a single file, called an ISO image, that contains all the data stored on the Windows 8 setup DVD disc.
This free program from Microsoft does everything includes properly formats your flash drive and then copies the contents of the Windows 8 installation ISO file you have to that in USB drive.
3.Start the Windows 7 USB DVD Download Tool program. You should be able to find the shortcut on the Desktop, as well as in your Start menu or on your Start screen.
4. Click Browse on the Step 1 of 4: Choose ISO file screen.
5. Locate, and then select, your Windows 8 ISO file. Then click Open.
Note: If you downloaded Windows 8 from Microsoft, check your Downloads folder or your Desktop for the ISO image. If you created an ISO image from your Windows 8 DVD, the ISO file will be wherever you created it to.
6. Click Next.
7. Choose USB device on the Step 2 of 4: Choose media type screen.
Note: As you can see here, there is also a DVD option. While it doesn't do much good in this case, since the end game is to get Windows 8's setup files on a flash drive, "you could also use this tool to burn a Windows 8 ISO image to a DVD or BD disc".
8. On the Step 3 of 4: Insert USB device screen, choose from the drop-down box the flash drive or USB-connected external hard drive you want to put the Windows 8 setup files onto and then click Begin copying.
9. Click Erase USB Device if you're prompted to do so on a Not Enough Free Space window. If you don't see this, don't worry, it just means that your flash drive or external hard disk is already empty.
Important: If this message didn't make it apparent, you should know that whatever data you might have on this drive is going to be erased as part of the process of getting the Windows 8 setup files copied.
10. On Step 4 of 4: Creating bootable USB device, just wait for the Windows 7 USB DVD Download Tool to prepare the drive and copy the Windows 8 installation files to it.
The first Status you see will be Formatting, which will take anywhere from a few to several seconds, depending on how large the USB drive is that you're using. Next will be Copying files which could take anywhere from 15 to 30 minutes, possibly longer, depending on which Windows 8 ISO file you're working from, as well as on how fast your flash drive, USB connection, and computer is.
Tip: Don't worry if the percentage indicator jumps ahead quickly but then sits on a single number for a very long time. It mean anything is wrong.
11. Assuming everything went as planned, the next screen should say Bootable USB device created successfully with a Status that says Backup completed.
Hurray.....
You can now close the Windows 7 USB DVD Download Tool program window.
12. Boot from the USB device that you just created to start the Windows 8 install process.
