Nokia Nseries Cellphones Hard and Soft Reset Techniques


Got problems with your Nokia Nseries Mobile Phone? I have got one solution to your problem, which is the Nokia Nseries Reset.


Problems from Nokia's mobile phone might be in the form of low memory, failed boot, virus infection or software errors.


To fix problems like these, a reset can be done by you without the expensive trips to cell phone doctors who charge you for repairing your phone for you. It is not a good idea to go to them for assistance right away for cell phone troubles like the ones I have just enumerated. When a reset is not successful, then that is the time to go to them for repairs.


The first reset technique is the Soft Reset which is a reset that can be done when you go to tools > general > factory settings option in your Nseries Menu. The sort-cut to this is by dialling *#7370#. This reset does work on other Nokia models so it is also a worth to try whenever you are having troubles with you Nokia cell phone. This reset will delete all of your contacts, notes, messages and everything stored in your phone memory so be sure to back up everything before you reset your phone. It does not, however, delete viruses running in the cell phone's memory card, if ever you have one. This reset is only possible when you can boot up your cell phone correctly. But when boot up is not possible you can try the next technique.


The next and the final and most effective reset technique for your Nseries Mobile device is the Hard Reset. A hard reset is effective at removing everything in the phone's memory. It is the most effective reset you could ever do whenever a virus infects your phone and prevents it from booting up. To do a hard reset there are two easy steps; 1) turn of your cell phone, 2) power on your cell phone while holding the asterisk (*) key, 3 and the answer key (green button) together (as shown below) until you see the Nokia Logo. You are done! You have a mobile that is as fast as the day you bought it.

GSM and UMTS

So you have a cell phone that has an option for GSM and UMTS but you don't know what to do with it. This page shows you little about what these two options in your phone are.

GSM or Global System for Mobile Communications is the most widely used network interface for cell phones in over 212 countries and territories. It had been used since 1991 and was by Radiolinja in Finland and was a joint technical infrastructure maintained from Ericsson. Over a million subscribers were then using GSM by the end of 1993 operated by 70 carriers across 48 countries. GSM works by searching for cellular networks in the vicinity or cells and connecting to it using radio signals. When a connection is established, users are then able to make calls and send text messages through it.

UMTS or Universal Mobile Telecommunications Network is built upon the concepts learned from GSM and is now operated by carriers worldwide, GLOBE, SMART, SUN Cellular, and Red Mobile included in our country. UMTS operates at newer frequencies that are capable of transmitting faster signals through and from cellular towers that are also supporting this new network interface. Faster data transmission allowed for newer mobile services such as video calling, email, and high-speed internet access that let you stream videos right to your mobile.

Although UMTS is relatively new and catchy, UMTS and GSM work hand in hand to bring the best in mobile phones. UMTS, however fast, is limited in coverage compared to GSM. But cell phones are set, by default, to use UMTS when available and switch to GSM when UMTS coverage is unavailable. But you can choose to use UMTS or GSM on your mobile.

Setting your phone to use UMTS is only useful when you are expecting a video call and you would not want your cell phone to switch to GSM by accident.

Another advantage of UMTS is that it does not disrupt other devices such as your computer monitor and speakers when you receive calls and messages. These disruptions are the annoying lines in the computer monitor and the unwanted sound in speakers whenever you make a call or send and receive text messages. These are caused by GSM radio signals that interfere with the operation of these devices. Since UMTS sends radio signals at a higher frequency, it does not disrupt other devices near it.

UMTS is 3G or Third-Generation standard while GSM is the 2G or Second-Generation. 3G shows up in the signal bar whenever we are connected in a 3G network. When we have 3G, we know we are connected to a faster network. We can send and receive emails faster and send text messages faster too without the annoying disruptions in speakers and in computer monitors. But when 3G is no covered, automatically, we are switched back to GSM when we have set our cell phone to Dual Mode which automatically switches our phone to either GSM or UMTS.

UMTS is available for most cell phones released after 2007 and is in every Nokia Nseries mobile phones.

64bit Operating Systems

With the demands of faster computing environments, 64bit compatible hardware and software are now possible for home computer usage. 64bit operating systems are also available for home use.

64bit computing is not new and has been around ever since the early 90's. They power supercomputers for the toughest of processes known to man back then. But since the demand for more powerful computers, 64bit computing has been offered to the masses with a range of 64bit ready hardware and software. Still, many use 32bit systems and have not moved to 64bit.

The key to a 64bit environment is in the CPU. A 64bit CPU handles 64 bits of data per clock cycle which is twice the data per clock cycle than a 32bit CPU. More processes per clock-cycle, more power. Another advantage of 64bit operating systems is in the amount of RAM (Random Access Memory) it can support. With a 32bit operating system, you are allowed up to 3 gigabytes of ram while a 64bit operating system can have more, about 16.8 million terabytes more RAM than the previous operating system. More RAM means faster application responses, more applications to be cached in RAM and lesser disk page-filing which is a function where data is written to the hard-disk for temporary storage.

Softwares such as CAD (Computer-Aided Design) applications are specifically targeted towards 64bit computing environment because of the extra performance it delivers when running these resource intensive applications. Games also benefit from the extra performance of 64bit systems to deliver realistic physics and more process to be run simultaneously for AI (Artificial Intelligence) to have realistic enemies in games. 64bit operating systems are also immune to certain viruses because 32bit applications are rarely supported in a 64bit operating system or would not actually run at all.

But do not be fooled. There are still factors to be considered such as the CPU's clock speed in Megahertz (MHz) which is the CPU's clock speed. Some of today's software is also designed to run in a 32bit system. Although some applications would run in a 64bit system, you would not see any difference in performance when you run it in a 32bit system. 64bit operating systems also require you to have 64bit hardware drivers for your keyboard, mouse, video-card, sound card and other hardware so be sure to download 64bit drivers before upgrading to a 64bit operating system. Application must also be optimized for a 64bit environment otherwise, it would not run fast or it would not run at all.

64bit computing isn't that new and is not that necessary of an upgrade. But for serious computer users like me, who use the computer for photo editing and CAD, it is best to take advantage of supercomputing power made for the desktop environment offered by 64bit Operating Systems and 64bit capable hardware and software.

Windows Vista Ready Boost to Improve Computer Speed

Does it bother you having a slow running windows vista environment and that you don’t have the money to buy addition RAM or Upgrade your system but you have a spare USB Flash disk around?



Well, you should try ready boost.



It is a very cool feature from windows vista that lets you use the extra space on your Flash Disk as RAM.



You probably think its a joke but it is true. In Fact, I am using it now.



You do have to have a USB 2.0 flashdisk so that you can enable this feature… The rest is just Plug and Play. So for Windows Vista Users, Its a must try feature for all of you.





Review on Windows 7 Release Candidte

One of the latest to come out from the line of Microsoft’s Operating Systems is Windows 7 or formerly codenamed as Blackcomb or Vienna. Windows 7 follows from its predecessor Windows Vista with aims to further increase compatibility with already compatible hardware in Windows Vista. Rumors also circulated that it was lighter on the hardware resources when compared to Windows Vista.

I got a firsthand copy from Microsoft’s own website that lets users download Windows 7 with its own serial number for evaluation purposes and here is what I experienced with the Operating System. It was an x64 copy of the Operating System since I had already installed a previous Windows Vista 64 on my desktop computer. After the download, I burned it into a DVD disk since the file was an image of the operating system that was 3.04 gigabytes in size.

1. The installer
The installer was the same as the previous version, Windows Vista. It had an option to upgrade or to install a fresh copy of the said operating system. You can either boot up using the disk or you can install it directly as an upgrade straight from the Windows Vista’s desktop. The upgrade was slow and tedious that took and estimated 3 hours of actual installation time. This is because I had already set-up numerous programs on my Windows Vista Operating System and I also have a lot of files in the My Documents folder. After installation was done, the usual activation takes place that needs an internet access to complete. When it was done, the desktop is already set-up. Since it was an upgrade, I no longer needed to add user accounts and I no longer needed to set-up the other programs. It was and easy upgrade.

2. Boot-up
Windows 7 boots up faster than Windows Vista. In fact it was an impressive boot. No more fancy moving boot-up screens. It was just a few seconds of black screen and you are done. But as I have noticed, Windows Vista loads the taskbar completely while Windows 7 doesn’t. It is observed that when you click the start button, or for Windows Vista and 7 is the Windows logo on the taskbar, you get a slight lag when the desktop is loaded and then you click it just after boot up.

3. User Interface
The look and feel is nothing different from Windows Vista with a slight change in the taskbar and the sidebar. The taskbar, by default, is now in the forms of buttons that when you hover over them, reveals previews of the windows that are on them. You can also pin and unpin programs onto the taskbar which is great from mostly used programs such as the Media Player and Internet Explorer. The sidebar is no longer called the sidebar and is no longer located on the side, as supposedly called the sidebar, but are now gadgets that sit anywhere on your desktop. The option for it can be found when you right click the desktop. The desktop also was redesigned to enable window snapping that lets you snap windows into place either in maximized window, or onto the side that lets you easily compare two windows at a time.

4. Taskbar
Another new innovation is the taskbar. It was redesigned to fit more applications at once. It was easy to navigate because windows can now be previewed as you hover over them in the taskbar. The windows are no longer placed as bars but as buttons that can be hovered onto to preview its content.

5. Personalization
The personalization option for the desktop and the over-all look for windows is also new. More colors and theme combinations are now possible with more sounds and more wallpapers to choose from. Dream Scenes were, however, discontinued with Windows 7 which is a big disappointment. But there is an option that lets you choose any picture to be as your wallpaper and have that change in time as you choose it to change. It fades into new wallpaper for every 10 minutes on my computer.

6. Hardware
This I didn’t like on this release of Windows. Drivers were still unsupported which is contradictory to their claim of having a Windows Operating system that was more compatible with hardware than Windows Vista. The sound driver that came with the operating system had to be set at 16bit to be able to get a clear sound. Playing games also proved to be of a disappointment since games lagged even more compared to Windows Vista. My scanner and cell phone was also not supported.

Over-all, Windows 7 release candidate was a big disappointment. Hardware is not yet fully supported by the release candidate. Games ran slower than Windows Vista and that after all of these, I could not downgrade to a previous version of Windows.
