How to update android
Posted by: 08.07.2018
Almost every user of mobile devices Samsung, Lenovo, Galaxy and the like faced some problems after downloading a new application or game. The picture hangs, the video slows down or the touch functionality slowly reacts when working with an editor. The root cause, most likely, is the emergence of a new version of the operating system, and there is nothing easier than to upgrade android for troubleshooting.
It should be noted that the development and updating of Android is performed continuously for the following three main reasons:
- Expansion of the range of mobile devices, where, in order to improve the reliability of the device and the functionality, the latest microprocessors, memory blocks, efficient firmware for receiving / transmitting audio, video and images can be used;
- Developments in the field of quality and speed of transmission of signals from the service providers of the Internet and telephony, including using the latest methods of encoding and compressing digital information;
- The emergence of fresh mobile applications, games, editors and other software products.
It follows that a fresh operating system is useful not only for installing new programs and games. After updating Android, the performance and performance of the tablet or smartphone itself can improve. At least, it was noticed even in slightly outdated models “samsung”, “galaxy”, “lenovo”, “xperia” and so on. However, the speed and quality of the Internet may increase. For example, this was clearly noticeable in the transition from conventional to 3G and 4G signaling technologies.
Update the OS on the phone.
The following step-by-step instructions provide details. кHow to update Android on the phone (smartphone):
- we charge the phone, at least 50% of the total battery capacity;
- connect to the Internet and make sure that we have enough traffic to download the update;
- open the “Settings” menu;
- go to the item "About the phone";
- select the option "System Update";
- press the "Update" button;
- We are waiting for the download of the Android update, reinstalling the system and rebooting the device. Now your phone is on new firmware.
Note that, depending on the firmware of a particular smartphone model, the names of functions and options may differ somewhat, including being in a foreign language. However, the procedure in all cases is the same and visually clear from the pop-up menus. However, in some models, authorization (account creation) may be provided. Then you first need to register and create an account, and then follow the above step by step instructions.
Update the OS on the tablet.
Unlike software for smartphones, the firmware of a tablet computer provides for automatic updating of the operating system. A notification about this from time to time pops up on the display, and the user is left to accept it by pressing "OK", or refuse - "NO". However, there are situations when you need to refresh the OS yourself. For example, if it is very rare to access the Internet or there is a rejection of automatic updates in the settings. In such cases, you can update the system in the same way as updating the android version manually on your smartphone, according to the step-by-step instructions above. The only thing recommended to connect the charger to the tablet. As practice shows, a full battery charge is not always enough for downloading, updating and rebooting the system.
Updating the OS using a computer.
It is not always possible to timely and correctly obtain the latest version of the operating system on a tablet or smartphone. There are many reasons for this, among which there is a weak mobile Internet via a SIM card or expensive roaming traffic. This problem can be solved using the following step-by-step instructions on how to update an android using a PC:
- We hammer into the search engine the request "application for installing Android from a PC";
- according to the issue, download one of the recommended ones, for example, Kies or New PC Studio;
- install the application on the computer;
- install the driver for compatibility of the tablet or smartphone with the computer;
- connect the mobile device to the PC using a USB cable;
- launch an application on your computer to update the operating system, which will automatically detect and find a fresh OS for a specific smartphone or tablet;
- The "Update" function will appear in the application window, click it;
- waiting for the transfer of files from a computer to a mobile device, updating and restarting the system.
Comment. Such manufacturers of mobile devices as "LG" or "Samsung" offer their own software products for installing and updating Android OS via PC. Keep this in mind as you follow the 1-3 steps in the instructions above.
Forced manual OS update.
It is noticed that some Chinese analogues of smartphones or tablets of little-known manufacturers do not have an automatic update of the OS. However, you can not get the latest version of any of the above methods. We offer how to update android on your mobile device forcibly using a flash drive.
- find the “ROM Manager” program in the Play Store, download and install it on the device;
- make sure that the batteries are fully charged, or do not disconnect from the charger;
- find the current version of the firmware for updating the OS and copy it to a USB flash drive (SD card);
- open the ROM Manager application;
- from the pop-up menu, select the option "Install ROM from SD card";
- Further we specify the path to the folder for saving data and files using the navigation table;
- Press the "Yes" button opposite the "Save current ROM" option;
- Click on the option "Restart and install".
Note. To work with the “ROM Manager” application, you may need a custom loader, about which the system will issue a notification. In this case, you need to find it, install it and follow the instructions given on the developer’s website.
If you failed to update the device using the “ROM Manager”, for example, because of problems with the bootloader, you can use the following reliable and universal way of updating via PC:
- we find the ADB Run program in the Internet, download and install it on a PC;
- in the mobile device, via the “Settings” item, go to the “Developer Mode”;
- there we tick off the option "USB debugging"
- install the compatibility driver for the mobile device from the PC and connect the smartphone or tablet to the computer via a USB cable;
- run the program "ADB Run";
- in the window that opens, we put Android into boot mode by typing the adb reboot bootloader command;
- in the same mode, we check if the PC sees the device with the “fastboot devices” command, if yes, the device’s serial number will be displayed, if not, check the connection and drivers;
- Next, we clear the “system”, “userdata”, “cache”, “recovery”, “boot” and “radio” sections with the corresponding commands “fastboot erase system”, “fastboot erase userdata” and so on;
- Place the previously downloaded update file into the “fastboot” folder and copy its name;
- then flashing all cleared partitions with the command “fastboot flash”, for example, for “system” - “fastboot flash system (copied file name)”, for “userdata” - “fastboot flash userdata (copied file name)” and so on;
- Finally, set the “fastboot reboot” command and wait for the reboot.
Roll back the Android system to the earlier version.
There are situations when the update is not quite satisfied with the user. In such cases, you can roll back (return) the OS to an earlier version that was installed before the update. To do this, you can use two methods. The first method - can be made directly on the device itself. To do this, go to "Settings", select the item "About phone" and click the option "System Restore." If for one reason or another it did not work out, you can use the second reliable method. Here we also use the “ADB Run” program in the same step-by-step sequence. The only thing to do in step 8 is to place the file with the version of the operating system that was before the update. It can be downloaded from the developer’s website on the model of a specific mobile device.
A few words about the official and unofficial versions of the OS.
We highly recommend using only official versions of the Android OS from developer sites. If required, create an account for this and register. The unofficial versions, for the most part, carry the risk of viruses infecting the device. Moreover, spyware programs that will transfer all actions on a smartphone or tablet, including financial ones, to third parties may not be authorized.
