The reasons why owners of mobile communication devices begin to study the question of “how to upgrade phones” can be very different. Some learn to change the software part of mobile phones out of curiosity, wanting to eventually receive additional functions; others try to make money from this, subsequently offering their repair services; Well, others want to restore the phone with their own hands.
The topic of mobile communication devices is now very popular, so finding information, for example, on how to flash a dead phone, is quite simple. Let's take a closer look at why the flashing is performed and what is required for this.
Update
It is known that the more complex the device, the more it is prone to failures. This is also true for mobile phones. No wonder developers periodically release update programs that eliminate errors and shortcomings in their products. However, it often happens that such support ceases, and all efforts are devoted to the development of new solutions (which allows stimulating demand). In this case, the owner can either use the failed device, or familiarize himself with how to flash phones, and perform this operation on his own. Here are just some examples that require updating the software: freezing when unlocking the screen, a broken camera, a Wi-Fi module failure, etc. In addition, having studied how to flash phones and “fill” the desired firmware, you can get additional functions or increase speed.
Device Preparation
Most modern phones do not require a computer to perform firmware updates. The user only needs to download from the Internet the desired firmware file designed specifically for this device and transfer it to the memory card. All contacts should be saved (imported to the drive). The same applies to installed applications (data will be lost). Further actions depend on the model, so there can be no universal instruction. As an example, we will look at how to flash an Android phone, since this particular operating system is the most popular.
Updating programs
The easiest way to upgrade the firmware is to use the built-in over-the-air update function. You must enable Wi-Fi Internet access in your phone, then proceed to “Settings - About phone - Software update”. If the developer has released a new firmware, it remains only to agree with its installation.
However, as we have already indicated, sometimes support is not properly implemented. Therefore, you can download the so-called custom firmware (with changes) for this model and place this file on a memory card. Many sources, which explain
how to flash phones, always indicate the need to obtain root rights. This is most conveniently done using specialized programs, for example, Framaroot. This allows the user not only to install custom, but also to change the entire software part. After obtaining root rights, you must enter recovery mode. To do this, turn off the phone, then press the power button and volume rocker. Keep pressed until a menu appears.
Procedure
For the correct update, you need to select Wipe Data / Reset, but for the first time you can skip this step (if the firmware is not installed, then the data will not be lost in vain). Then, the menu item Update from zip is indicated (the name may differ. Meaning - the source and path to the file are selected). After the operation is completed, it remains to select the reboot item and wait for the operating system to load (sometimes you have to wait several minutes). In some cases, a preliminary installation of a prepared recovery is required. So simple. However, we recommend installing custom only with full understanding of what is being done and why, since full compatibility with the device is possible only in official firmware.
