Probably, there are several people who would begin to delve into this issue after they tried to independently return the version of the operating system to the previously installed one. But, faced with some difficulties, they would decide to read on the net to figure out what these difficulties may be associated with. And then it turns out that there are many nuances that need to be foreseen in advance.

In addition, from a huge number of foreign names and abbreviations, instead of understanding the process, information in my head turns into a mess. And each sentence read adds to the overall picture more and more misunderstanding.

Well, let's figure it out together!

Brief educational program

There is no universal algorithm of actions! This is the first thing to know about downgrading Android. Each brand (and even model!) Device may have its own characteristics.
Returning an OS version is a process that affects the system's core. Consequently, manufacturers make sure that only "advanced" users can get there. For this, Root rights were invented. They are intended to give you administrator privileges. There are pluses and minuses in their application. Before you start doing anything, find out how to get them and what the use of Root rights can promise on your device!
If you are not scared by everything you read about Root rights and you are also full of confidence to return Android version 4.4, then another concept that needs to be understood before starting the process is Backup. Speaking Russian -.

After returning the system, you can easily restore all contacts, applications, settings, and more. The main thing is to choose the right program that will make Backup on your device as correct as possible.

How to get your Nexus back

The developer of the Android operating system and the manufacturer of Nexus devices is one company - Google. Therefore, for Nexus devices, the return process remains as simple as possible and consists of 4 simple steps:

Download and install the image of that Android firmware that you need;
Run this firmware directly from the device and wait for the installation to complete;
Load data from backup.

How to return everything else

Devices from other manufacturers have their own specifics when performing a system rollback. But despite this, there are still general manipulations.

You will need a PC or laptop

Typically, to downgrade Android 5.0 to 4.4 or similar, you will need:

Required firmware;
Backup software;
A program for establishing Root rights;
Personal computer or laptop;
The device (tablet, phone) on which you need to make a return;
USB cable.

Firmware

The first thing to take care of is, of course, the firmware itself. You need to clearly understand and imagine what you want to see as a result of manipulating Android. Decide which firmware you want, custom or official? Official firmware can usually be downloaded from the official website of your device manufacturer. Custom - search forums, compare and choose. It is necessary that the firmware is suitable for your device and is known to be working, that is, verified. To find out, you will have to study more than one forum, read a lot of reviews and ask a bunch of questions. But this must be done, since otherwise you risk saying goodbye to your favorite device!

The selection of custom firmware should be approached responsibly

Backup

The main rule of any gamer or programmer is "Save !!!" And in our case, this rule is of the same importance.

Has the function of creating a backup with saving in your Google account. But in this case, only contacts can be saved. Therefore, it is necessary to acquire the necessary program. And then you can reserve almost everything: contacts, messages, system settings, and information about applications, thanks to which the system will automatically download them from Google Play and install them.

But, whatever one may say, you again have to make a choice yourself. We will only list the most popular programs today:

Titanium Backup
GO Backup
HTC backup
Clickfree Mobile Backup.

Can be used various programs to save data

The backup process looks about the same for all devices:

Insert a memory card into your mobile device;
Search, read reviews and download your favorite Backup program to your tablet or smartphone;
Install it and run it;
In the program settings, mark what you want to reserve. Don't forget to check in the settings if there is enough space to save the backup. You need this free space on the memory card;
Start the backup process, wait for the end, take out the card.

Now all important information is on the flash drive and after returning your Android from version 5.0 to the previous one, it will be restored using the same program.

Root

An additional program is required on your device. You also choose, read reviews, ask questions, compare. Then download and install on your computer.

Process directly

So, you are all set to start the process. Recall that this process is individual for each device, so we will focus on the manipulations, which are the same in most cases. We present you the order of actions:

Making Backup (see above);
We transfer the device to the programming mode (it can be called differently; see the instructions);
We connect the device to the computer;
We launch the Root program;
Run the downloaded program and select its version;
We start the installation process, wait;
At the end, it is advisable to reset the settings to the factory settings;
We reinstall the program with which you did Backup, insert the memory card with the backup, start the data recovery process.

Conclusion

In conclusion, I would like to make out another concept that you will surely come across in the process of studying the forums. This is the concept of "brick". A “brick” is a device that stopped working at all after returning from Lollipop to Kitkat. To prevent this from happening with your Android device, you need to approach the matter as carefully as possible and scrupulously study all aspects. Only after the whole picture of the planned actions is clear and clear, you can be sure of a successful result.

Google and the developers of programs for smartphones or tablets based on android are constantly developing updates, trying to make them better and fix bugs.

In this case, if you do not prohibit them, then they will be installed automatically, although the system usually asks if you want to update.

Only sometimes the process can go wrong and there will be problems. What to do then? Those who have already dealt with the computer, of course, will try to do a rollback.

But android is not Windows and such a function as in a computer is not provided in it.

For example, on your Asus or Samsung phone, when you bought it, there was android 4.4 and over time the system was updated to android 5.1, but this firmware did not suit you.

Before that, you had android 5.0, 4.4.2. Is it possible to do an automatic rollback to 5.0 or 4.4.2 No, it is impossible, only to 4.4, just like you can not roll back the android system for a week or a month, as in a computer or laptop.

This is just an example, to show you how to rollback, you can only go to the version that was installed at the factory.

Still, there are some nuances. Let's take a look at them - if you are in no hurry, read about them below.

How to roll back the system on android - to the previous version

So, after updating the firmware, the operation of a smartphone or tablet does not make you happy, so we will roll back to previous version, more precisely to the factory firmware.

NOTE: if you need a previous firmware, then you can only install it, so to speak, reflash it yourself, after downloading it.

IMPORTANT: if you roll back the system update to the factory firmware, you will lose all data, including contacts, photo programs, and so on, except for those stored on the memory card.

Therefore, think carefully, perhaps it is better to tweak something in the installed on this moment version of android and continue to use it.

If you nevertheless decide to roll back, turn off your smartphone or tablet and use the following key combination:

most often you need to hold and hold two buttons: on and volume down.

on HTC - press and hold the volume down button and then briefly press the power button. When the recovery menu appears, release the volume down button. Find "Clear Storage", select it by clicking on the power button and confirm the action with the volume down button.

If you follow the steps described above, you will be taken to the "Android system recovery". There you will see several options.

highlight - will move you around the menu;
select - select a specific menu item;
"Wipe data / factory reset" - roll back the phone to the factory one (after pressing, you need to confirm).

After selecting "wipe data / factory reset" in the new menu, go down to the action confirmation sub-item and select it.

Now wait for the reboot, and then get the android firmware that was installed at the factory. Some of the above written little is clear -.

How to roll back settings to android

To roll back the android settings in all versions of smartphones or tablets, you first need to open the settings.

Further actions slightly depend on the version of android. I will show you with pictures from a Samsung Galaxy smartphone with Android 6.0.1.

Thanks to the Google Play service, app developers for Android phones and tablets have the ability to efficiently distribute updates to their products. As soon as they update the application in the Google Play service, it is automatically updated on all Android devices where it is installed. In most cases, this is very convenient. For both developers and users.

But, updates are not always successful. Sometimes after updating the application does not work stable or contains errors. In such situations, there is a problem, how to uninstall the application update on Android and return it old version.

Removing updates for Android apps

Fortunately, the Android operating system provides a mechanism using which you can remove the update that was installed on your phone using the Google Play service. To do this, you need to open the Android settings and go to the section " Application Manager" or simply " Applications"If you have a standard shell.

After that, you will see a list of all installed applications on your Android smartphone. Here you need to find the app you want to remove the update from.

When you open the desired application, you will see a screen with information. Here you need to click on the "Remove updates" button, which will be located immediately under the name of your application.

Every year, Google releases a fresh version of its own operating system for mobile devices- Android. It is the most widespread and overtakes its direct competitor from Apple - the iOS system. Its popularity among users is due to the greater freedom of action that this shell provides and the many settings that are inaccessible to lovers of "apple" devices. But sometimes situations arise when it becomes necessary to roll back to an older firmware version. This is especially true in cases where the user initially did not uncheck the box in the settings automatic update systems. But not everyone knows how to return the old firmware to Android.

The need for updates

Before talking about how to get old firmware back to Android, it should be mentioned why Google releases periodic updates. This includes not only global changes in the form of completely new version OS, but also various patches or patches.

Their main purpose is:

correction of identified bugs in the system;
decrease in power consumption (Android with each new update becomes less power-hungry, which allows you to get more time autonomous work without increasing the battery capacity);
resolving hardware problems (this includes camera, sound, multimedia capabilities).

But not every user is happy with innovations. Some, after the next update, dream of returning the old firmware version.

This may be due to a violation of the stable operation of the device, especially if a new version of the system is released, which does not pass full testing on all supported devices. New additions may also include add-ons in the form of services that cannot be removed.

It should be noted right away that when deciding how to return the old firmware on Android, it must be borne in mind that, unlike, for example, Windows, the default rollback function is not provided on a smartphone or tablet. Therefore, when returning to the previous version of the OS, you should be prepared for the loss of all data.
