How to Flash a Phone Using a Computer

By the verb “Flash” the device, we mean the procedure for installing the platform. However, the process of installing the operating system for the computer and for the mobile gadget on the Android platform is significantly different. The reasons for this are a huge variety of implementations of this very common OS in mobile devices. A lot of software is created individually for certain models of smartphones and tablets. Therefore, often for inexperienced users, the installation of a new firmware fails due to a lack of information and a lack of correct action algorithms before their eyes.

The manual below will help you reflash Android at home, as well as introduce you to the possible risks of the procedure and how to minimize them.

Why do I need to reflash an Android phone?

People make and program gadgets, so no device is completely immune from errors. In the event of a failure in the smartphone (tablet) on Android, the cardinal method of getting rid of the problem is flashing.

Arguments “For” OS reinstallation

Thanks to the openness of this operating system, manufacturers are free to improve and customize it to fit their gadget models. Many of their advanced software has already won the love and trust of users. In this regard, often the owners of smartphones and tablets take risks and decide to reflash their electronic friend. Also, some developers contribute to this, which eventually cease to release updates for their gadgets. Users from various sources of information will learn about new software modifications that can allow optimal use of the hardware capabilities of the device and, of course, are wondering how to reflash Android.

Even very well-known companies that produce smartphones and tablets are not infrequent in installing their own software, which for obvious reasons is not suitable for most users. In addition to the unsuccessful appearance of the shell, these proprietary software significantly slows down the functioning of the device. In this case, a clean Android, not stuffed with unnecessary marketing chips from the developer, often amazes with its high performance and stability. Therefore, the answer to this question is the installation of custom software, in which there is no pre-installed “trash” from the manufacturer.

Arguments Against OS Reinstallation

With a lack of experience or insufficient care, there is a great risk of getting an inoperative and useless piece of microcircuit and plastic after the procedure, or as the experts used to call this failed device. “Brick”.

In the case of firmware with software taken from unofficial sources, the device warranty is void.

Not all drivers included in the software package from a third-party developer work correctly with the components of the gadget.

The success of any event depends on how thorough the preparatory preparations were.

Preparatory activities include the following main points:

  • Manual installation (For models from different manufacturers, different firmware methods are used using different software called “Flashers.” For example, for gadgets from Samsung, the Odin program is used, for Nexus, Sony and HTC. “Fastboot”, “Lenovo”. “Flash Tool”, “LG”. “KDZ Updater”, etc.).
