Updating your operating system is a key process to maintaining the security and stability of your device. Manufacturers regularly release patches to fix vulnerabilities and add new features to improve the user experience. Ignoring these releases may cause your device to become vulnerable to malware or stop working correctly with modern applications. Many users put off the procedure for fear of losing data or bricking the gadget. However, if you follow a certain algorithm of actions and understand the difference between types of updates, the risk is minimized. In this article, we will analyze in detail all the ways to obtain a new version of software, from automatic notifications to manual flashing via a computer.

Many users postpone the procedure for fear of losing data or “bricking” the gadget. However, if you follow a certain algorithm of actions and understand the difference between types of updates, the risk is minimized. In this article we will analyze in detail all the ways to obtain a new version of software, from automatic notifications to manual flashing via a computer.
Before taking active steps, you need to assess the current state of your smartphone. Check the battery level, free memory space, and Internet connection stability. These three factors are the foundation for the successful installation of any system package.
Preparing the device for installation of a new software version
The first and most critical stage is backup. Even if you plan to use a secure over-the-air update method, there is a non-zero chance that the data recording process will fail. Save important photos, contacts and documents to cloud storage or external storage.
Free up enough internal memory. System update files can take up from 2 to 5 gigabytes, and the unpacking and installation process requires even more free space. If your drive is full, the installer simply will not be able to complete the procedure.
Make sure that the battery charge level is at least 50-60%. Ideally, connect the device to a charger for the entire duration of the process. A sudden power outage while writing system partitions can lead to serious software errors.
⚠️ Attention: If your smartphone was previously rooted or has an unlocked bootloader, the standard update may not install or lead to rooting. In such cases, a special approach to the firmware is required.
☑️ Ready for update
Automatic update through settings (OTA)
The easiest and most common way to get a new version is technology OTA (Over-The-Air). The system independently checks for the presence of new packages on the manufacturer’s servers and notifies the user. You don't need to download files manually or use a computer.
To run the scan, go to your device's settings menu. The path may vary slightly depending on the shell, but usually it looks like this: Settings → System → System update. On Samsung devices, the path may be Settings → Software update, and on Xiaomi - About phone → MIUI version.
Click the “Check for updates” button. If a new version is available, the system will prompt you to download and install it. You can choose to install immediately or postpone it overnight. In the latter case, the phone will reboot itself at the specified time.
If the update downloads very slowly, try switching from Wi-Fi to the mobile network for a couple of seconds, and then back - this sometimes resets the frozen connection.
The installation process takes from 10 to 30 minutes, depending on the size of the package and the speed of the flash memory of your smartphone. During this time, the screen will display the Android logo or installation animation. Do not touch the device during this period.
Manual installation of updates via Recovery Mode
Sometimes automatic updates do not arrive due to regional restrictions or errors in the Google Play service. In such cases, you can perform the installation manually by downloading the official firmware file from the manufacturer's website. This method requires more care.
You will need to find a file with the extension .zipspecific to your smartphone model. Loading the wrong firmware may result in the device not working. After downloading, move the file to the root of the internal memory or to a microSD card.
Next you need to go to recovery mode (Recovery Mode). To do this, turn off the phone and hold down the key combination (most often Volume Up + Power Button). In the menu that appears, select Apply update from storage or Install from SD card.
⚠️ Attention: Never select
Wipe data/factory resetif your goal is to simply update the system. This item will completely delete all user data from the device.
What to do if Recovery does not see the file?
Make sure that the firmware file has the correct .zip extension and is located in the root of the memory, and not in a folder. Also check the file checksum (MD5) to ensure the integrity of the download.
Find the downloaded archive in the list of files and confirm the installation. After completing the procedure, select item Reboot system now. The first launch after a manual update may take longer than usual, as the system optimizes applications.
Updating via a computer using proprietary utilities
Large manufacturers such as Samsung, Sony, Huawei and Xiaomi offer their own apps for managing smartphones on a PC. These utilities often allow you to restore the device or update it when the mobile network or Wi-Fi is unavailable.
For Samsung users this is the app Smart Switch, for Sony - Xperia Companion, and for Xiaomi - Mi Flash Tool (for advanced users). Connect the phone to the computer with the original cable and launch the corresponding application.
The app will automatically detect the device model and current software version. If an update is available, a button will appear. This method is considered one of the most reliable, since a cable connection eliminates download interruptions due to network problems.
| Manufacturer | Name of the utility | Features |
|---|---|---|
| Samsung | Smart Switch | Full backup and recovery |
| Sony | Xperia Companion | Software Repair |
| Xiaomi | Mi PC Suite | Official support is limited |
| Huawei | HiSuite | Convenient interface for backups |
Using a PC utility is the best way to save your phone if it does not boot or reboots cyclically after an unsuccessful update.
Features of updating on custom firmware
Users who have installed custom firmware (for example, LineageOS, Pixel Experience) have their own update path. Standard OTAs from the manufacturer do not work here, unless the firmware author has implemented his own update system.
Most often, the update is carried out through a custom recovery, such as TWRP. You need to download the new firmware version and, if necessary, the Google Apps package (GApps). The process is similar to manual installation, but requires clearing the Dalvik/ART cache.
In the TWRP menu, select Wipe, then check the boxes Dalvik / ART Cache and Cache. Do not touch the Data and System sections if you do not want to lose data. After cleaning, return to the main menu and install a new zip archive of the firmware.
⚠️ Attention: When upgrading to a new major version of Android (for example, from 12 to 13) on custom firmware, a full data reset (Full Wipe) is often required. Be sure to read the instructions (changelog) for a specific version before installation.
Solving common problems when updating
The process does not always go smoothly. Users may experience a download error, stuck on the logo, or a "Failed to check for update" message. Most often, the reason lies in an unstable Internet or lack of memory.
If the update freezes during the download phase, clear the cache of the Downloader or Google Play Services application. Go to Settings → Applications, find the desired application and select Storage → Clear cache. After that, try running the scan again.
If the phone does not turn on after the update or does not work correctly, you may need to reset it to factory settings via Recovery. This is a last resort measure that will delete all data but return the system to a working state.
Sometimes the problem is that the device is too old to receive official updates. In such a situation, the only way out is to install custom firmware that supports newer versions of Android for your hardware.
Why is the update not officially arriving?
Manufacturers limit device support to 2-3 years. After this, the servers stop sending update packages to older models, even if technically they can work faster.
Frequently asked questions (FAQ)
Will the update delete my photos and applications?
With a standard update via OTA or a proprietary utility, all user data is saved. However, when moving between major versions of Android (major update) or when using custom firmware, a data reset is sometimes required. Always make a backup copy before starting the process.
Is it possible to interrupt the update if it takes a long time?
It is strictly not recommended to interrupt the installation process, especially after rebooting the device. Interrupting the recording of system files may cause the phone to stop turning on. If the update is frozen for more than 1 hour, only then should you consider the options of a forced reboot.
Why is my phone not updated to the latest version of Android?
It depends on the manufacturer’s policy and the age of the device. Budget models often receive fewer updates than flagship models. Also, the update may come in waves to different regions, so you should wait a few days or weeks.
Is it safe to update if the phone is unlocked for the operator?
Usually yes, but there are nuances. Official OTA updates are safe. However, manual installation of firmware from other regions or custom assemblies can lead to loss of the network unlocking function or problems with the operation of mobile frequencies.
Do you need to remove root access before updating?
Yes, the presence of root access (SuperSU, Magisk) often blocks the installation of official updates or leads to errors in checking the integrity of the system. Before updating, it is better to temporarily remove root or use special modules to save it if you are an experienced user.
