I would like to discuss how to upgrade iphone firmware in this article, It is always better to have the latest firmware updated with your handset. iphone updated with latest security fix, advanced features, software update etc.
Firmware is a computer program that is designed for a specific hardware device and is usually embedded inside it. The main benefit of firmware in commercial technology is that it can easily be updated even after it has already been distributed to customers in manufactured devices. Apple has already provided several firmware updates to the firmware for the iPhone, correcting a few bugs from previous versions and making it extremely easy to firmware update with some basic directions.
iPhone Firmware upgrade instructions
Firmware update Step 1 Back up any media, photos, contacts or other information that you have stored on your iPhone before beginning the process to upgrade its firmware. It is a good idea to save this information to your computer’s hard drive, an external flash or other memory storage drive or DVR before installing this update. This will prevent you from permanently losing any of this content during the installation process, as the iPhone may inadvertently remove some files as it updates its internal system.
Firmware update Step 2 Restore your iPhone to its original settings if you have installed any unauthorized software, such as independently designed games or applications, to your iPhone. If you have used hacking methods to jailbreak your iPhone, the firmware upgrade may not install properly. Therefore it is extremely important to completely restore your iPhone by plugging it in your computer, launching iTunes and clicking on “Restore” in the main menu, which will automatically reset your iPhone to its default settings and wipe its memory clean.
Firmware update Step 3 Connect your iPhone to your computer if you have not already done so and allow iTunes to launch. iTunes will notify you that there is a firmware update available. A pop-up message will appear as soon as the program recognizes your iPhone and will ask whether you would like to install the upgrade. It is best to upgrade firmware immediately, but if you prefer to wait until a later time you can click on “Don’t Install” and iTunes will automatically give you the option again the next time you connect your iPhone to your computer.
Firmware update Step 4 Allow iTunes to install the firmware update, refraining from using any other programs on your computer until the process is complete. Do not attempt to use your iPhone during this process either. You will not be able to receive any calls or messages during the firmware update.
Firmware update Step 5 Unplug your iPhone from the computer when the installation process has finished and iTunes notifies you that is safe to disconnect. Confirm that your iPhone’s firmware has been successfully upgraded by turning on your iPhone and tapping on the “Settings” icon on the home screen. Tap on “General” and then “About” and you will see the version number and date of the latest firmware update.
\In this post you will be able to find a list of different download links which can be directly used to download the correct Firmware update file for the device you own. You need to find out the version of your device through the General Settings option and then proceed towards the restore of the same.
