What should I do? Android crashed. What to do if the firmware on Android crashes?

Twitter

Android, for several years in a row, has been one of the most common operating systems for various mobile devices. A huge advantage of this OS is that it is open source, thanks to which manufacturers, developers, and just hobbyists can create their own versions for various gadgets, as well as modify existing ones.

It is worth noting that some amateur “customization” projects have gained quite wide popularity and become commercial ( Cyanogen Mod, MIUI, AOKP, Slim ICS etc.).

Reasons for reinstalling Android

There are many reasons to reinstall the Android OS on your tablet or smartphone. Here are just a few of them.

Many, even well-known manufacturers, do not bother themselves at all with developing and releasing new versions of the system for devices already in use - what can we say about inexpensive devices produced by little-known companies. But each new version of Android is the result of bug fixes from the previous one, plus additional new features. As a result, the existing hardware allows you to use a new version that is impossible to obtain standard means updates.
Most manufacturers use their own modified version. Yes, of course, some “tricks” are very pleasant and useful. But, often, the manufacturer’s image is so inconvenient and overloaded additional software and settings that even those with good characteristics devices noticeably slow down in operation. So installing a “clean” ROM that does not contain unnecessary software, allows for more efficient use of available capacity.
Ready-made third-party images, even if they are built on the same base Android versions, have so attractive appearance and functionality, and the software included in them is so optimized and has such wide customization options that, having tried it once with friends, the owner of the gadget wants to install the same one for himself.
Reasons for use third party firmware Android a lot. It is worth noting security (many “custom” ones have a built-in antivirus and firewall), improved work with RAM for a specific device (long-standing problem Google developers), better drivers (for example, cameras or Wi-Fi), etc., etc.

Finding the required system version

Finding a new or modified Android OS image is as simple as it is difficult. For most common models there are so many of them that it is very easy to get confused in their number. For rare models, especially from a little-known manufacturer or one just starting to enter the market, on the contrary, there are practically none. And if there is, it is unknown by whom and how they were developed.

The search for an alternative image should still start from the official website of the developer, not trusting those downloaded from suspicious torrents or forums. The exception is proven resources, where the administration monitors the quality of uploaded files.

So, to search for firmware from Cyanogen you need to go to http://download.cyanogenmod.org/, where on the left side of the page you can find your device manufacturer and model, and select the type:

all — complete list, or select by release:
stable - stable release;
release candidate — release candidate;
nightly - “nightly”, constantly updated assembly;
experiments - experimental;
snapshot - a snapshot of the file system.

A little about types of releases

For those who just want to update their image to CyanogenMod, the stable release is worth a look. All functions in it have been tested, the drivers work as they should. In general, the title of the release speaks for itself.

Release candidate. Relatively stable assembly located at final stage testing. Some roughness is smoothed out. The good thing is that it may include some experimental features that are missing in the stable release.
Nightly build - has an advanced set of features, drivers, etc. Not the most the best option for installation on a daily used tablet.
Experimental- the name speaks for itself. There is no guarantee that it will work stably.
Snapshot - usually used to restore “dead” devices.

For Samsung owners Galaxy HTC One And Google Nexus there is an opportunity to take advantage in an automatic way installing a custom version using the CyanogenMod Installer application package, which we’ll talk about below.

How to update Android firmware on a tablet

The easiest option to update the ROM is to use, for example, the CyanogenMod Installer installation packages. Using this software is quite simple.

First, . apk file is installed on the tablet and checks the “correctness” of the settings for this operation.
The second file is an installation file for Windows or Mac OS, which is installed on the computer, respectively. After launching on the BB, the program searches for the most suitable image on the Cyanogen server, and then offers to connect the device via USB, after which the download process begins required version, and its installation into the device.

This method is currently available to owners of only a few of the models listed above. But, there are other options for installing the firmware, although they require a little more time, but also have greater capabilities. In particular, the choice of type or manufacturer.

How to reinstall Android

In order to correctly install a new or modified version of the Android OS, you first need to obtain Root rights to access ROM device. You can use one of the many available on Play Application Market, For example, Frameroot, Universal AndRoot, z4root or the like.

Now you can begin installing the new image using the following procedure:

Download the required firmware;
Save all data and also make a system backup;
Download necessary software for installation. One of the most popular is ROM Manager;
Move the downloaded firmware to the memory card if it was located in internal memory tablet;
Launch ROM Manager and select the option: “Install ROM from SD card”;
Select the image to install;
Check the “Save current ROM” option so that you can return to the “stock” version in case of failure;
After the reboot, the installation of the new ROM will begin.

Before starting work, it is advisable to completely format the memory card. To do this, go to: “Settings” - “Memory” and select “Empty SD card”.
If you fail to flash your tablet or phone using ROM Manager, you can try using ClockWorkMod.
To search for an alternative image, you can use the built-in tools of both flashers. Both ROM Manager and ClockWorkMod use databases from all the most popular developers.
It is also worth remembering that all of the above actions are performed at your own peril and risk. And after changing the Android OS, the warranty on the device, if you still have it, will no longer be valid.

Computer technology does not stand still; operating systems are constantly being improved. And modern software is being developed for the new OS. As a result, it may turn out that one day you will not be able to install an interesting application on your phone. computer game, because a notification will appear indicating that you have Android outdated version.

The first thought is to take the smartphone to service center and entrust the reshuffling of the operating system to professionals. Great choice– this way you will get rid of the hassle and protect yourself from the risks that inevitably arise when upgrading yourself computer equipment. You will have to pay money for flashing and wait several days.

If you belong to the category of users who prefer to do everything themselves, there are options on how to update them yourself operating system Android on your phone. True, in this case you accept all responsibility for the risks. The likelihood of damaging your gadget through inept intervention is quite high.

Attention!!! If you decide to complete reinstallation, then try better first! Perhaps this will solve all your problems and won't require any reinstallation! If you just need to slightly refresh a gadget that has started to slow down, you may not need to look for a newer version. Recovery normal operation it will be enough to reset custom settings and simply roll back the system to factory state.

The problem is that each model requires its own firmware, developed by the manufacturer's programmers. Unlike Windows OS, which is quite well unified and suitable for almost any computer, in the case of the Android mobile OS there is a significant variety of versions that are not compatible with each other and with other people's phones.

Where to get a suitable distribution for installation

Where can I download the new version of Android from? The best and safest way is to visit the official website of the manufacturer of your device, find the section for your specific model and look there available updates. If you find suitable version Android on sites of independent developers, the level of risk increases significantly. By at least, it is advisable to discuss the issue with one of your friends who has already had such experience Android installations and the experience was positive. Otherwise, prepare in advance the amount of money to buy a new smartphone. You can reinstall in such a way that even the hardware will be completely destroyed - the microcircuits will burn out or something worse. Although it's much worse.

In general, you should only reinstall the operating system if you absolutely need it. For example, your smartphone began to slow down and glitch; the applications you need for business or games for entertainment do not work at all.

You should not reinstall Android just because “everyone ran and I ran.” Any experienced engineer will confirm to you: “If the device is working normally, there is no need to do maintenance, much less repair it.”

Well, if your cell phone is really broken, then the cards are in your hands - you can experiment, gain experience and learn something useful.

Find Backup and reset. Select Reset. Don't forget to reserve all important documents in advance. external card memory or cloud storage.

The system will reset, and you will receive the gadget as if it had just come from the store, clean and ready for further testing.

Many users of devices on this platform have to think about how to properly reinstall Android on their phone. This step is often prompted by the system itself, which, due to its openness, provides wide scope for experimentation. Despite this, you should be very careful and think about how advisable it is before the procedure itself.

Why is it worth reinstalling Android?

Lack of device support from some manufacturers. Even the most well-known companies they often do not want to release the latest OS versions for relatively outdated devices so that their owners buy new smartphones. But there is another way out - installing custom firmware based on new version Android, in which bugs have been fixed, various optimizations have been carried out and security vulnerabilities have been eliminated.
The desire to get a “clean” version of the OS. The fact is that almost all famous manufacturers of Android devices equip them with their own shells with numerous additions, which are not always appropriate. For users tired of an overloaded OS, firmware without unnecessary software will be a real breath of fresh air. And the device itself will work faster and more stable.
Availability of products from other manufacturers who were able to make their firmware more optimized and beautiful.

Don’t forget about forced flashing when the device stops functioning normally, and resetting to factory settings does not solve this problem. In such cases, it is best to completely “demolish” the existing firmware and completely install the new one. Before this procedure, be sure to create a backup copy necessary information and applications.

Upload contact list to Google account. To do this, go to the settings of the “Contacts” application, select the “Export” option and tap on the “Google” button in the pop-up window. After flashing, to restore your contact list you only need to log into your account.
Create a file with the extension “.vcf”, from which contacts can later be transferred to almost any phone. To do this, you need to follow a procedure similar to saving to your account, only in last step select “Phone memory”. It is best to save the file on your computer, since the firmware process often deletes some data from the device’s internal memory, and sometimes from the SD card.
Save contacts to SIM card.

It is also advisable to save photos, music and videos on your computer.

On devices with processors from MTK, you can install Recovery using the MTK Droid Tools or Mobileuncle MTK Tools program.

In the case of devices on Snapdragon processors, Kirin and Exynos in most situations you will have to resort to flashing the firmware via a cable using a PC. To do this, you can only use programs and drivers from the manufacturer, but the process itself is more intuitive, understandable and safe. To implement it, you just need to download and install all the software from the manufacturer, copy the firmware to your computer and follow further instructions.

The basic rule for flashing firmware via a cable using a PC: under no circumstances should you interrupt the process until the program gives a signal that it is complete. This way you can significantly reduce the likelihood of getting a “brick”.

Features of the procedure for different devices

If your device has official firmware based on Cyanogen Mod, you can simply download installation package CyanogenMod Installer, install it on your smartphone and PC, and then run the Cyanogen utility on the latter. Most often, only owners of flagship devices from HTC, Samsung and Google have this option.
