Computer

Computer is an Electronic Machine which receives input from user, stored it, proceed it and give output which is useful for mankind. Modern computers are electronic and digital. The actual machinery -- wires, transistors, and circuits -- is called hardware; the instructions and data are called software.

Network

A network is a group of two or more computer systems linked together. There are many types of computer networks, Including Local-area networks (LANs), Wide-area networks (WANs), Campus-area networks (CANs), Metropolitan-area networks MANs), home-area networks (HANs)

News

News has two priorities: it must be current, and it must mean something to people. A story about the environment and a story about the Oscars can both be newsworthy, for different reasons. On the surface at least, the objective of news is to inform the audience. It's the job of all the news media to tell people what's going on in their community - locally, nationally or globally. In this sense, the news media provide a valuable public service.

Mobile Prices

A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device that can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station.

Wallpapers

On a computer that is provided with a desktop kind of user interface, wallpaper is the background pattern or picture against which desktop menus, icons, and other elements are displayed and moved around. A wallpaper image can be in a JPEG or a GIF file format.

What is Difference Between Recovery Mode and DFU Mode

3:48 AM , 0 comments

The Main difference between the Recovery mode and DFU mode is iBoot. Recovery mode uses iBoot during restoring or upgrading your iPhone while DFU mode bypasses the iBoot so you can downgrade the current firmware because there is no iBoot agent during the DFU mode. About iBoot, iBoot is the bootloader on iPhone OS devices. iBoot acts on restore while iPhone is in Recovery Mode, iBoot makes sure that you are flashing a firmware version greater than or equal to a current one. If you are not, iBoot will not allow the restore to proceed. Because of this, firmware downgrading must be done in DFU mode.This means if you need to restore your iPhone to current version simply put the iPhone in recovery mode and iTunes takes care of the rest but if you need to downgrade your current firmware to lower one you need to put your iPhone in DFU mode. For example you can’t downgrade Firmware 3.0 to Firmware 2.2.1 without entering in to DFU Mode.
DFU Restore
Recovery Mode : Recovery Mode is a state of iBoot that is used during standard upgrades and restores. As iBoot is active, it does not allow you to downgrade your device’s software. Also, unless it is ‘pwned,’ it will not allow custom firmware to be flashed.
DFU Mode : DFU Mode is a special mode where the device can still interface with iTunes, yet it does not load the iBoot. The screen will appear totally black in DFU mode, so you can’t guess whether the device is in DFU or powered down from simply looking at the screen. Because iBoot and the OS are not loaded this exploit makes us able to downgrade your iPhone firmware or upgrade with a custom firmware created by Pwnage tool.
How to put your iPhone in recovery mode :
  1. Turn the device completely off and disconnect it from cable/dock.
  2. Hold down the home button.
  3. While holding down the home button connect to a computer with a cable (easiest) or dock.
  4. Keep holding down the home button until you see a connect-to-itunes screen You are now in recovery mode.
To escape Recovery Mode and power the phone off simply hold down power and home buttons for ten seconds.
How to put your iPhone in DFU mode :
  1. Connect your iPhone to your computer.
  2. Turn iPhone off.
  3. Hold power and home together for 10 seconds (exactly).
  4. Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
  5. A few seconds later iTunes should detect your iPhone.
  6. If the Restore Logo is present on the screen, you are in Recovery Mode, not DFU.
