4 Sure Ways To Unlock Nokia Phones Without Security Codes

This post was last updated in February 2017. And all the methods listed are working perfectly on different models of Nokia devices.

Today, I will be sharing with you guys, four best, solid, simple, convenient, stress-free and unbelievable ways to unlock any Nokia device at your disposal, without actually having any idea of what the unlock codes really are.

These methods has proven to have worked perfectly in unlocking both old & new Nokia phones: Symbian, Nokia Java S40, s60, and even the new Nokia Asha series.

I will try my possible best to make this as easy as possible. But before I begin, I know by now you may be thinking of using this trick on your girlfriend/boyfriend, Dad / Mum to know what's really hidden behind those security codes of theirs or to be able to carry out certain transactions on their phones without their approval. But before you do, kindly keep it in mind that;


It is completely illegal to invade one's privacy without one's consent/prior notice. And that this post is only for educational purposes nothing more.



How To Unlock Any Nokia Phone Without An Unlock Code


Method One (1)


This method is simple and requires no expertise whatsoever. The easiest on the list and works mostly on Old Nokia devices.


Steps

==>While phone is locked and on Standby mode,
==>Tap and hold Unlock (center button) Till you see "press * to unlock".
==>Press * and the phone should be unlocked.

This is almost same, as the default way of Unlocking all Nokia Automatic keyguard locks without security code on it. But the difference is; you have to hold the center button "still". Not just pressing it.


Method Two (2)


This method of unlocking your Nokia phone without unlock code requires the use of the phones 15 digit IMEI to generate a 10 digit Master unlock code you can use to unlock the phone at any time.


Steps

==>While the phone is unlocked, dial *#06# to retrieve the Phones 15 digit IMEI or open the back case of the phone and carefully copy out the imei written there.
==>Goto http://www.unlockitfree.com and click on "Free Remote Instant Master Code".
==>Enter the 15 digit IMEI number of the phone you wish to unlock and click on Generate.
==>Copy the 10 digit master code generated. And use to unlock phone whenever you wish to unlock it.

Method Three (3)

Method three works perfectly in unlocking the newer sets of Nokia s40 java phones like Nokia 2690, 2700, 3110c, 5130, 2626 etc


Normally when it is not locked, you will need to press the Center button then * to unlock. But since it's locked, after pressing the Center button, followed by *, you will then be required to provide the unlock code.


To bypass that and unlock without code follow this steps.

Steps

==>Turn On the Nokia device, and allow to finish.
==>While on Standby mode, dial 112 (Emergency number) and Tap the Green call key to send.

==>Wait for one (1) second and hit the top right "End Call" key to terminate the call.

You should notice that the phone forgot its self for a second and displayed Goto by the left side, Menu at the center and Music, Media, Calculator etc on the right depending on what's preset.

==>Now when you notice that quickly Tap Menu (center button). This should take you to the phone menu.

==>Repeat the step again but this time tapping the Navigation keys towards Phone settings.

==>Under settings, Goto Phone=> Automatic keyguard. And turn it Off. The phone should now be wild open.

When done, you can easily turn Automatic Keyguard back ON, then Use Menu followed by * to lock. So as not to leave traces if the phone isn't yours.



Method Four (4)


I call this the oracle method. I'll say Nokia really did a very big mistake by letting this loop hole exist in most of its phones. Its the simplest and fastest way to unlock the new Nokia Asha series devices, without any code whatsoever, no master code needed, no software.


Phones include Nokia Asha 200, 201, 202, 203, X2, etc


And you know what? I revealed it to my little Nokia freak cousin, and the first week, he used it in unlocking his phone each time instead of using the actual unlock code.


And the next week, he removed the security code completely stating it was completely useless. And opted for an Android phone. Not knowing an Android phone can also be unlocked without its correct pattern too. Soon I will be talking on how to bypass an Android lock pattern as well. But for the mean time;



nokia asha 201
Steps
==>While phone is locked and on Standby mode,
==>Hit Unlock (center button) followed by *. As if you want to unlock, but instead of the code.

==>Input 911 as the code and hit the Green Call key to send.
==>Immediately after sending, Tap the top right End call key twice to unlock.

==>The phone should now be unlocked. And shall remain open till you reboot the Nokia device.

Method Five (5)
If after using all of the above methods on your Nokia device, and non seem to work for your model, you are left with one final option which will definitely work but will cost you money. And that's seeking the help of a professional/engineer/technician. 
phone technician

You can find them at phone repair store or kiosks and all you have to do is tell them the problem of your phone and they will get it unlocked for you using a software and a computer through a process called flashing to format/reset the phone password. 

Howerver, this method could lead to you loosing all the existing files such as contacts, pictures, video, music/audios etc. So be prepared so as not to be caught unaware. And if you are in Nigeria, the price is just withing the range of N1000 to N2500 depending on the model of your Nokia phone.

Over To You
All of the above methods are 100% effective and safe, in unlocking Most Nokia phones locked with security codes in few minutes without cracking, hacking of any kind. No PC required too. However, if you are still having problems getting by this post's explanations, and need more light thrown to it. Don't hesitate to use the comment box.

Top 5 Tips to Boost Performance of Your Android Phone

Android devices are used to perform the range of tasks which affects device speed and performance negatively over time. If you have noticed the performance issues and slow speed on your device due to cluttered and unorganized data, it’s time to clean it up. Your device speed may also affect due to various other reasons like hardware or software issues etc. To deal with it, you can perform a thorough research of your device to find solutions to boost your device performance. Let’s discuss some tips here to help you with this. 

==>1. Disable Bloatware: Bloatware includes all those apps and programs which come pre-installed on your device from the manufacturer. These apps and programs can be manufacturer based or third-party based programs. Most of these apps include those tools which you don’t use or don’t intend to use in future thus they prove to be space-hogging only. These apps affect your device speed and performance negatively as they not only occupy precious storage space but these apps run in the background as well. 

Unfortunately, you need to root your device (which has its own limitations) to get rid of this bloatware on your device. Alternatively, you can “Disable” them so that they can’t update themselves, run in the background or appear in your app drawer. To disable bloatware on your device, go to Settings > Application Manager > All Apps > Select the app you want to disable and click on “Disable” or “Uninstall” button.

==>2. Use technology: Using technology to keep your device intact is another good way to boost speed and performance of your Android device. You can use various apps like Android cleaning apps, duplicate file remover apps, battery saver apps etc. to get better and instant results. These effective tools help you clean your device and improve its performance effortlessly. 

==>3. Clean your App cache: Apps on your device generate cache files regularly and these files accumulate in large numbers over time. These cache files when accumulated in large numbers starts creating problems for your device speed and performance. Thus it’s better to remove all these files to recover some storage space and boost device performance. To do this go to Settings > Storage > cached data and hit OK to delete the cached data. Alternatively, you can delete cache files of individual apps by heading to Settings > Application Manager > All and select the app to clear cache data. 

==>4. Update your device: Android keeps on sending you latest firmware updates on regular intervals. These updates include some important improvements to each new release of the Android operating system. These updates ensure higher performance, better stability of device functions, better speed & connectivity, bug fixes and lot more. Thus you should respond to every system update notification. You can also check available updates by heading to Settings > About device > Software Update > Update.

==>5. Use High-speed memory card: When you add storage space to your device in the form of memory card it helps you improve your device speed and performance. Cluttered and unorganized data on your device affects device speed and performance negatively. Thus having additional storage space to manage data helps you declutter and organize your device storage space. You can add memory according to value it supports which generally varies in between 2GB to 32 GB to support high-speed read and write operations. You can select memory cards of Class 6 or Class 10 for better performance. 

You can follow these simple steps to speed up your device performance significantly. Following these simple steps altogether can show some prominent results and changes in your device. In fact, this way you can save a lot of your time and efforts as well. 

Summary: Android devices starts creating performance related issues due to prolonged used. There are certain steps you can follow to boost your device speed and performance. Let’s discuss some of these steps here.

How to View That Forgotten Wireless Network Password in Windows

Did you have someone else set up the wireless network in your house, and can’t for the life of you remember the password? If so read on to see how you may still be able to recover it.
This should work for Windows 7, Windows 8, and Windows 10.

Note: Unfortunately this trick will only work if you are a local administrator on your machine, if you are not you will be prompted by UAC for administrative credentials.
image

Viewing Your Wireless Password From an Already Connected Machine

To view your wireless network password we need to get to the settings for your network adapter, so press the Win + R keyboard combination and type ncpa.cpl in the run box, then hit the enter key.
image
You will now see all the network adapters in your machine, right-click on the wireless one and select Status from the context menu.
image
When the Wi-Fi Status dialog loads up, click on the Wireless Properties button.
image
Then you will need to switch over to the Security tab.
image
Finally, check the Show characters checkbox to reveal your password.

That’s all there is to it.



How to Find Out Why Your Windows PC Crashed or Froze

Computers crash and freeze. Your Windows PC may have automatically rebooted itself, too — if so, it probably experienced a blue screen of death when you weren’t looking. The first step in troubleshooting is finding more specific error details.

These will help you identify the problem. For example, the tools here may point the finger at a specific device driver. This could mean that the device driver itself is buggy, or that the underlying hardware is failing. Either way, it will give you a place to start searching.


bsods


Check the Reliability Monitor


The Reliability Monitor offers a quick, user-friendly interface that will display recent system and application crashes. It was added in Windows Vista, so it will be present on all modern versions of Windows. To open it, just tap the Windows key once and type “Reliability.” Click or press Enter to launch the “View reliability history” shortcut.
 If Windows crashed or froze, you’ll see a “Windows failure” here. Application crashes will appear under “Application failures.” Other information here may actually be useful — for example, it shows when you installed various pieces of software. If the crashes started occuring after you installed a specific program or hardware driver, that piece of software could be the cause.
img_55a5f7cc607b0
You can use the “Check for solutions to problems” link here for some help. However, this feature usually isn’t very helpful and it’s rarely found possible solutions in our experience. In a best case scenario, it might advice you to install updated hardware drivers.


The Reliability Monitor is useful because it shows events from the Event Viewer in a more user-friendly way. If not for the Reliability Monitor, you’d have to get this information from the Windows Event Viewer itself.
To do so, launch the tool with a Start menu search for “Event Viewer,” select “System” under “Windows Logs,” and look for “Error” messages. These are the same error messages you can view in the Reliability Monitor. However, many other messages you don’t need to care about are also displayed here.

View Blue Screen Crash Dump Details


Windows saves crash dumps from blue-screen errors to your system. For a more user-friendly way of examining these, we recommend NirSoft’s free BlueScreenView utility. (We don’t usually like recommending third-party software, but we do trust NirSoft.)
This tool will examine and memory dump files created during blue-screens and display a list of them. In particular, the important information here is the “Bug Check String” — the same message that’s displayed on your screen when the blue screen itself appears. Search for this message online and you’ll find information that can help you identify and solve your actual problem.
The list of drivers at the bottom of the window may also be helpful. For example, the blue-screens may consistently implicate a particular driver file, such as your graphics hardware driver. This may indicate there’s a problem with that specific driver. Or, that specific driver may be crashing because the underlying hardware itself is damaged. Either way, it can help point you in a more specific direction.

If you see a blue-screen while it happens, you can also just read the “Bug Check String” from it. On Windows 10 and Windows 8, Windows now displays a simple blue screen message with only a small note at the bottom of the screen with the message you might want to search. On Windows 7 and earlier versions of Windows, the bug check string appears near the top of the blue screen instead of at the bottom.
These blue-screen messages only stick around so long because Windows automatically reboots after a blue-screen. You could disable the auto-reboot feature to have Windows not reboot when it encounters a blue-screen. However, you can also just use the BlueScreenView utility to view the Bug Check String displayed on the blue screen after it happens.

But Why Is it Crashing?

The above tools can help you get more of a handle on the actual problem. With a specific crash message from the blue screen message in hand, you can at least perform a web search to discover what might actually be the problem. It’s a much better starting point than looking for generic information about why a computer crashes or freezes.
If your computer just crashed or froze once, don’t sweat it. Nothing is completely perfect — a bug in Windows or a hardware driver could have caused the crash, and you may never see it again. You should worry when your computer is crashing regularly and consistently. Modern Windows PCs should not be blue-screening regularly at all — this should be an extremely rare occurrence.

If you’re encountering a lot of crashes, you may want to skip most of the troubleshooting process entirely and perform a “PC Reset” on Windows 10 or Windows 8. This will quickly set Windows back to its factory-default state, fixing any system corruption problems and removing any buggy drivers or malware that’s causing problems. You will have to reinstall your installed applications afterwards. On Windows 7, you’ll just have to reinstall Windows. If this doesn’t work, you’re probably experiencing a hardware problem. (But, bear in mind that if you install the same hardware drivers after resetting Windows and experience the problem again, it could be those drivers.)
The Memory Diagnostics tool built into Windows can also help. It will test your memory to ensure everything is working properly. If your memory is damaged, this can cause system instability and blue-screens.

Ultimately, it’s impossible to give advice that will solve every problem. The tools here will help you nail down your issue to a more specific error message or hardware driver and give you a way to start troubleshooting. But not every problem can be fixed with some software troubleshooting — your computer may have a hardware problem and there may be nothing you can do about it beyond replacing or fixing the hardware itself. As Windows becomes more stable, regular system freezes and blue-screens often point to underlying hardware problems.



How to Unlock Your Computer with Your Phone or Watch

Everyone wants to replace the password with something better. Well, we already have smartphones — and some of us even have smartwatches. These tools can log you into your computer with a smartphone or smartwatch.

The best, most polished options are available for Mac users with iPhones. Solutions available for Windows and other platforms are much more limited.
iphone and macbook

Mac and iPhone or Apple Watch

Mac users with iPhones have the most — and most polished — options available:
Knock allows you to use either an iPhone or Apple Watch to unlock your Mac. Walk up to your Mac with your iPhone on you and it will communicate with your Mac using Bluetooth Low Energy. Knock on your phone’s screen — even if it’s just in your pocket, knock on your pocket — and it will unlock your Mac. There’s no need to even pull your phone out of your pocket, much less turn its screen on.
There’s now a Knock Apple Watch app for unlocking your Mac, which provides some good security — if someone puts your watch on, they won’t be able to authenticate and unlock your Mac. If someone grabs your phone and you’ve set up Knock, however, they’ll be able to log into your Mac unless you remotely disable Knock.
Knock costs $3.99 for the iPhone app. You’ll also need the Mac app installed on your Mac — that’s available for free.

Tether works entirely using Bluetooth Low Energy. Walk up to your Mac and your iPhone and Mac will establish a connection. Tether will automatically unlock your Mac when you approach. Walk away from your Mac with your iPhone on you and Tether will notice the iPhone is no longer in close proximity, automatically locking your Mac for you.
There’s now a Tether Apple Watch app, too. One concern with this solution is security — if you’re nearby your Mac in the same area, it will automatically be unlocked. If someone grabs your phone, they can approach your Mac and have it automatically unlock for them. It’s up to you whether this is good enough security for your needs.
The Tether apps for both iPhone and Mac are free. Tether offers in-app purchases for additional functionality, but the standard auto-unlock and auto-lock features are free.

MacID takes a different approach. Rather than automatically unlocking your Mac, it allows you to unlock your Mac from your phone. This means you can use the Touch ID sensor on your iPhone to authenticate and unlock your Mac.
As with Knock and Tether, MacID also offers an Apple Watch app. Unlike with the above options, MacID can’t be used by just anyone who has your iPhone and Mac. It requires a bit more work because you have to actively log into your Mac via your phone, but that may be appealing to you. If your Mac has a long, strong password, using Touch ID on your phone could certainly be faster.
MacID’s iPhone app costs $3.99 on the App Store, and the required Mac app is available for free.

Chromebook and Android Phone


Chromebooks deserve an honorable mention here because Google has integrated a way to unlock your Chromebook with an Android phone. This feature is named Smart Lock, and it requires an Android phone with Android 5.0 or newer.
If you have a modern enough Android phone, you can quickly set up Smart Lock and pair your Chromebook with your phone without any third-party software. This feature doesn’t yet support Android Wear watches for some reason — you need an Android phone.

Windows PC and Android Phone

Similarly polished options for Windows just aren’t available. Previously, the most popular option was BTProximity, which used the proximity of a Bluetooth-enabled device (such as your smartphone) to automatically unlock your Windows PC.  We can’t find any comparably polished solutions to replace it at the moment.
You can still rig up something to do this yourself with various tools on Android. This solution requires EventGhost on your Windows PC to do the unlocking work, AutoRemote for communicating from your phone to your Windows PC, and Tasker for automatically sending a signal to EventGhost via AutoRemote when certain conditions are met.
The Unlock PC from Android discussion over at StackExchange has some detailed information on setting this up.

Mac and Android Phone (or Any Other Bluetooth Device)

If you have a Mac and an Android phone (or any other Bluetooth-enabled device), you could use the free Proximity tool for Bluetooth proximity detection and set up AppleScripts that unlock and lock your Mac depending on the proximity of the device to your Mac. This requires some manual setup, but it should work similarly to Tether when you’re done.
Lifehacker provides AppleScript code that will do this in this post.

Linux and Any Bluetooth Device

On Linux, try the BlueProximity application for locking and unlocking your PC in response to the proximity of a Bluetooth device. It should be available in your Linux distribution’s software repositories, but may require some configuration before it automatically locks and unlocks the PC correctly.

If you’re sick of unlocking your phone constantly, Android 5.0 provides other “smart unlock” features. These can automatically keep your phone unlocked when you’re connected to your home Wi-Fi network, for example.



How to Create Bootable USB Drives and SD Cards For Every Operating System

Creating installation media for your operating system of choice used to be simple. Just download an ISO and burn it to CD or DVD. Now we’re using USB drives, and the process is a little different for each operating system.

You can’t just copy files form an ISO disc image directly onto your USB drive. The USB drive’s data partition needs to be made bootable, for one thing. This process will usually wipe your USB drive or SD card.

Use a USB 3.0 Drive, If You Can


For only $15, it’s a great upgrade
USB 2.0 has been around forever, and everything supports it, but it’s notoriously slow. You’ll be much better off making the upgrade to USB 3.0 since the prices have dropped dramatically, and the speed increases are enormous… you can get 10x the speed.
And speed really matters when you’re making a boot drive.
Editor’s Note: We use this Silicon Power USB 3.0 drive here at How-To Geek, and at $15 for a 32 GB version, it’s well worth the upgrade. You can even get it in sizes up to 128 GB if you want.
Don’t worry about compatibility, these faster drives are fully compatible with an old USB 2.0 system, you just won’t get the speed boosts. And if your desktop computer doesn’t support USB 3.0 you can always upgrade it to add support.

For Windows 7, 8, or 10

Use Microsoft’s own Windows USB/DVD download tool to create a bootable drive you can install Windows from. You’ll need a Windows installer ISO file to run this tool. If you don’t have one, you can download Windows 10, 8, or 7 installation media for free — you’ll need a legitimate product key to use them, though.
Provide the ISO file and a USB flash drive and the tool will create a bootable drive.

Alternatively, if you’re installing Windows 10, you can download an ISO or burn Windows 10 installation media directly using Microsoft’s Media Creation Tool.

From a Linux ISO


There are many tools that can do this job for you, but we recommend a free program called Rufus—it’s faster and more reliable than many of the other tools you’ll see recommended, including UNetbootin.
Download the Linux distribution you want to use in .ISO form. Run the tool, select your desired distribution, browse to your downloaded ISO file, and choose the USB drive you want to use. The tool will do the rest. You can see a full step-by-step guide here.

You can use similar tools on Linux. For example, Ubuntu includes a Startup Disk Creator tool for creating bootable Ubuntu USB drives.

From an IMG File

Some operating system projects provide an IMG file instead of an ISO file. An IMG file is a raw disk image that needs to be written directly to a USB drive.
Use Win32 Disk Imager to write an IMG file to a USB drive or SD card. Provide a downloaded IMG file and the tool will write it directly to your drive, erasing its current contents. You can also use this tool to create IMG files from USB drives and SD cards.

Linux users can use the dd command to directly write an IMG file’s contents to a removable media device. Insert the removable media and run the following command on Ubuntu:
sudo dd if=/home/user/file.img of=/dev/sdX bs=1M
Replace /home/user/file.img with the path to the IMG file on your file system and /dev/sdX with the path to your USB or SD card device. Be very careful to specify the correct disk path here — if you specify the path to your system drive instead, you’ll write the contents of the image to your operating system drive and corrupt it

For DOS


If you need to boot into DOS to use a low-level firmware upgrade, BIOS update, or system tool that still requires DOS for some reason, you can use the Rufus tool to create a bootable DOS USB drive.
Rufus uses FreeDOS, an open-source implementation of DOS that should run whatever DOS program you need to use.

From Mac OS X Installation Files


You can create a bootable drive with Mac OS X on it by downloading the latest version of OS X from the Mac App Store. Use Apple’s included “createinstallmedia” tool in a terminal or by run the third-party DiskMaker X tool.
The Mac OS X drive can be used to install OS X on other Macs or upgrade them to the latest version without any long downloads.

From a Windows ISO for Mac


If you plan on installing Windows on a Mac via Boot Camp, don’t bother creating a bootable USB drive in the usual way. Use your Mac’s Boot Camp tool to start setting things up and it will walk you through creating a bootable Windows installation drive with Apple’s drivers and Boot Camp utilities integrated.
You can use this drive to install Windows on multiple Macs, but don’t use it to install Windows on non-Apple PCs.

Some of these tools overlap — for example, Rufus can also be used to create bootable drives from Linux ISOs, IMG files, and even Windows ISO Files. We suggested the most popular, widely recommended tools for each task here.
