How to install Android: how to roll up a clean OS on your phone, instructions

Smartphones and tablets are very complex devices, to the development of which each manufacturer tries to approach as responsibly as possible. This concerns not only the hardware of the gadget, but also the software. Despite the fact that most modern devices initially have Android installed, some may need to install it from scratch. Next, let’s understand why this is necessary, and how to install Android yourself.

When is it necessary?

A new device bought in a store is initially ready to go. After the first launch, the user will be greeted by the standard Android screen and the last thing he will think about is to install the operating system independently from scratch.

However, there are cases where you can’t do without it:

  • The OS initially installed on the phone does not work correctly;
  • the device is based on the manufacturer’s proprietary shell (MIUI, OneUI, and so on), and the owner wants to use pure Android;
  • the purchased smartphone is based on the Chinese version of the firmware, which does not provide for the Russian language;
  • improper installation of the previous update, due to which the gadget malfunctions.

Of course, not all of the identified reasons are valid. In particular, the desire to use a bare Android, rather than a shell from the developer – pure taste. However, such factors as the malfunction of the device or the lack of Russian language leave the smartphone owner no choice, and he has to install Android from scratch.

How to install a clean Android on your smartphone

The possibility of independently installing the OS is not initially provided by the developers. After all, any official device receives updates by air, and the owner only needs to press the “Update” button in time when receiving an update.

The fact that the manufacturers themselves do not recommend reinstalling the operating system makes this process quite complicated and dangerous. Therefore, those who decide to install a bare Android should follow all the requirements of the instructions, acting step by step, in order to avoid mistakes.

Back up your data

Since the procedure is quite dangerous, it is important to do everything possible not to lose personal data during the installation of the operating system. Therefore, before performing the operation, it is recommended to transfer all files to an external medium or other device, or better yet, make a backup copy:

  • Open the phone settings.
  • Go to the “Restore and reset” section.
  • Click the “Backup” button.

Next, you need to choose where you want to save the backup. It may be the internal memory of the device, and then you’ll have to transfer the copy to an external drive. Another option is to upload a backup to Google Drive cloud storage. However, here you may need to subscribe for a fee, since the cloud initially provides only 15 GB of free space.

Perform a factory reset

In order to ensure that the Android does not conflict with the software, you need to perform a factory reset. This operation will lead to a complete deletion of all files saved on the smartphone. But if you have prepared a backup, you should not worry. To clean it, you need to:

  1. Open the device settings.
  2. Go to the “Restore and reset” section.
  3. Press the “Reset Settings” button.

Note that the smartphone may offer several reset options. You need to select the factory reset option. Then the next time you turn on the device, its internal memory will be empty not only of multimedia files, but also of account data.

Install and get root rights

It is possible to manually install Android only if you have superuser rights (root access). To get them, you need to activate root through a special application like SuperSU, which is available for download in the app store Play Market.

Important. Granting root rights entails serious consequences (for example, removing the device from the warranty or blocking transactions). To avoid facing restrictions, you must revoke root after reinstalling the OS.

Update Recovery on your device

You won’t be able to reinstall the OS through your smartphone’s standard menu. Therefore, you will need a special Recovery environment, which in principle resembles the BIOS on a computer. There are several variants of recuperation, but we recommend using CWM Recovery. To install it, you need to:

  • Install the ROM Manager application on your smartphone.
  • Run the program.
  • Go to “Recovery Setup” and then “ClockWorkMod Recovery”.
  • Select the phone model and click “Install”.

Now you are almost ready to install the operating system. Next, you need to act as carefully as possible, because even a minimal error can lead to the failure of the smartphone.

Download and install Android

First you need to download the Android installation file. You can find it through your computer on the manufacturer’s website or any third-party resource. Next, you need to transfer the ZIP file to a MicroSD card and follow the instructions:

  • Insert the SD card into the phone.
  • Run the recovery by turning off the smartphone and pressing “Power” + “Volume Up” + “Volume Down” buttons (combination may vary depending on the manufacturer).
  • Go to the “wipe data/factory reset” tab and confirm the settings reset.
  • Then go back to the main recovery menu and select the “install zip from sd card” option.
  • Specify the path to the location of the firmware file.

Then the installation will start and will end with rebooting the device. If you follow the steps correctly, you will see a clean Android screen without any add-ons or extra apps.

Possible problems

The procedure described above will seem complicated to most users; therefore, it is possible that you may encounter a number of problems, up to and including “bricking” your smartphone after the installation is complete. To avoid this, take note of a few recommendations:

  • download software designed for your model;
  • don’t use pirated versions of Android;
  • If you have problems with the installation, rollback the settings through the recovery.

If you follow all the requirements, the operation will not cause you difficulties. It is only important to allocate enough free time to perform a manual reinstallation of the OS.
