Firmware cm 12.1. Install the CyanogenMod firmware using the CyanogenMod installer. Where to download and how to install CyanogenMod

I don't know who in the feed is interested in my posts about the phone, Android, CyanogenMod and other boyish nonsense. The place for them, probably, is in specialized forums. And yet. The number of Android users has exceeded 1.5 billion, maybe my experience will help someone cope with such challenges.

So. After flashing Xiaomi Redmi 2 with MIUI 7.1 (Android 4.4.4) to CyanogenMod 12.1 (Android 5.1.1), my joy quickly changed to sadness when, with incoming calls, I saw the following picture on the screen:

I didn't know which of the two SIM cards they were calling me - the information about the operator was cut off. This is important to me. For example, I call my daughter on MTS from life, because it's cheaper for me, and it's cheaper for her to call on MTS. But since she is still a child, sometimes, through inattention, she just dials my last call. It's the same with parents. Therefore, it is important for me to control which SIM card the incoming call goes to, and, if necessary, reset and call back myself. Anyway, so I know whether they call me for work or not. In MIUI 7.1, with an incoming call, on the screen next to the caller's number there was a small SIM card icon with the number 1 or 2. Not very informative, but at least you could see it if you wanted to. Here is complete ignorance.

When you change the language in the phone settings to Ukrainian, the same, even shorter:

With outgoing calls, as you can see, everything is ok, there are no words "operator" and everything fits on the screen:

The problem was solved only by changing the phone language to English, where everything is short and clear, but unusual:

It is especially difficult with the English language to find the desired item in the phone settings, and I was barely used to the Russian location. And I started to play with phone themes that can be downloaded and installed from Google Play. I tried the mass, everything changes, but the text is still truncated upon an incoming call. Until I installed the theme 2nd PitchBlack ™ (DarkRed)... And, lo and behold! All information about an incoming call fit on the screen:

What is in this thread that is not in the rest? Again a lot of experiments and comparisons, and finally the obvious came to me: it's just a matter of fonts. In this thread, it is narrower! Perhaps not the most beautiful, but it meets my needs. In the end, I settled on this mix: I took only fonts from the 2nd PitchBlack ™ (DarkRed) theme, from

Samsung offered the official Android 4.4.2 firmware for the Samsung Galaxy SIII (AT&T i747, d2att) back in June last year. We haven't heard anything about the official Android 5 firmware yet. After testing the official version of Cyanogenmod 12.1 for AT&T Samsung Galaxy s3, based on Android 5.1 Lollipop, I realized that I didn't want to go back. This is the fastest firmware I have ever had. The abandonment of the Dalvik virtual machine in favor of ART can play a significant role in this.

Fortunately, Android is open source (at least for the Android Open Source Project or AOSP), so you don't have to wait for manufacturer updates if enthusiasts have suggested firmware for your device. Even the very popular Samsung Galaxy SIII (AT&T i747, d2att) was long avoided without offering the official Cyanogenmod 12 firmware, although there were many unofficial Android 5 firmwares on xda developers.

Although there are many different Android 5 firmwares for AT&T Samsung Galaxy s3, I chose the official version of CyanogenMod 12.1. Even unofficial versions of CyanogenMod I prefer to bypass. Even the official one assumes the installation of a new bootloader, modem, as well as Google Apps. Despite being open source, there is always a risk of catching malicious software. Therefore, of course, the official firmware may be preferable. On the other hand, official firmware is updated very rarely, therefore, due to the presence of unpatched vulnerabilities, it may not be so secure when using the Internet on a smartphone.

I liked CyanogenMod 12.1 because all applications were restored after flashing. However, I don’t know if I should thank the previous CyanogenMod or Google firmware for this. I have used both for synchronization. But it is Google that allows you to save a list of applications and, if you wish, even their settings, so for sure it is synchronization with Google that helps restore applications. Although you have to log in at the same time in every application that requires login to your account, again.

How to install Android 5.1 Lollipop (Cyanogenmod 12.1) firmware on Samsung Galaxy SIII (AT&T i747, d2att)

Warning: When flashing the phone, something can always go wrong. Use the firmware instructions below at your own risk.
As of May 26, 2015, Bluetooth may not work correctly on nightly builds of CyanogenMod 12.1. In addition, there may be problems with the camera, but you can install a free application.

CyanogenMod notifies when updates are available. They can be downloaded immediately from the settings menu. True, in the latest versions, when installing them directly from Android, the error "E: Zip file is corrupt! E: Error installing zio file" @ / cache / recover / block.map ""

In this case, you can still install the firmware update. To do this, you need to reboot in Recovery mode, then select Install ZIP and select the archive, which is downloaded from the settings to the cmupdater folder on the phone.

Update (June 6, 2015)
I've been testing cm-12.1-20150529-NIGHTLY-d2att.zip for over a week now. Absolutely satisfied with everything, there were no problems at all. So I recommend installing CyanogenMod 12.1 on your Samsung Galaxy s3 AT&T!

Update (June 16, 2015)
I've been testing cm-12.1-20150606-NIGHTLY-d2att.zip for over a week now. Everything is still stable. Apps are now easier to find as they are listed alphabetically, each next to the corresponding letter the app starts with. "Over the air" or OTA updates are now installed without error.

Update (June 24, 2015)
On the previous firmware cm-12.1-20150606-NIGHTLY-d2att, Google Apps suddenly started to fail. At the same time, an error constantly occurred, and the phone began to get very hot, while the battery was discharged quickly even after disconnecting data transmission and navigation. Installed cm-12.1-20150620-NIGHTLY-d2att.zip and new Banks GApps.

Update (June 26, 2015)
The camera did not work on the previous firmware cm-12.1-20150620-NIGHTLY-d2att. When using it, the error "I can not connect to the camera" began to appear. I installed cm-12.1-20150625-NIGHTLY-d2att.zip, after which I turned off data recording with shooting coordinates in the settings. Photo and video works.

Update (Dec 28, 2015)
On the previous firmware cm-12.1-20150625-NIGHTLY-d2att.zip did not like enabling / disabling Wi-Fi, although I could not find fault with the rest. Installed cm-12.1-20151228-NIGHTLY-d2att.zip and

New custom firmware Android 5.1 Lollipop is now available for Galaxy Note 2 (3G) GT-N7100.

While there are rumors that Samsung is planning a new 5.0 Lollipop OS update for the 2012 flagship Galaxy Note 2 phablet, it seems to us that this may not be the case since the Galaxy Note 2 is over two years old. The contract to create updates for 18 months has already expired, so the company is no longer obligated to release new updates for the phone.

Impatient Galaxy Note 2 owners can try out the sweet Google mobile OS v5.0 by installing the new CyanogenMod software on their device.

The new custom firmware is based on AOSP (Android Open Source Project) v5.1 Lollipop, and is said to have new custom settings to make your device unique, a new interface, quick access to applications and many custom options, for example:

• OpenGL (CPU playback)
• MALI blobs (GPU playback)
• HWComposer and MALI R3P2 Drivers
• Rotation
• Camera
• Wi-Fi
• Bluetooth
• NFC (Android Beam)
• Sensors (Everyone!)
• Internal / External SD Card
• Vibration
• Main button wake up
• Simlock
• Signal icon
• Soft keyboard on first boot
• Mouse pointer
• H / W video playback
• Options settings and many other changes aimed at satisfying users

This new CyanogenMod CM12 custom ROM was developed by a senior member of the XDA Developer Forum Ivan_Meler. But we want to remind you that CM12.1 is an experimental version, so some bugs have not been fixed yet. We advise you to read the entire article first before you start installing your custom ROM.

Requirements (things to remember when installing a custom ROM)

• This new CM12.1 series Android 5.1 Lollipop firmware from CyanogenMod should only be installed on Samsung Galaxy Note 2 GT-N7100 3G model (Exynos chipset). If you try to do this on other devices, they can turn into bricks. [To check the model go to: "Settings" \u003e\u003e "About phone" \u003e\u003e model number].
• Make sure the device is rooted before starting the custom ROM installation.
• Installing a custom ROM requires clearing your smartphone's memory, so make sure to back up your data by installing Clockwork Mod (CWM) Recovery / TWRP on your smartphone.
• Make sure you have installed USB drivers on your PC, otherwise the computer will not recognize your smartphone (Samsung Galaxy Note 2 GT-N7100).
• Make sure the device has more than 80 percent battery power, otherwise the smartphone has a chance to temporarily get bricked if the installation process is interrupted in the middle.
• While installing a custom ROM will improve performance and improve the user interface of the device, it will also void the company's warranty and will no longer be responsible for future updates [users can restore the warranty by flashing the device with a stock ROM].

[Denial of responsibility: this procedure is technically complex and must be performed by someone with deep knowledge of rooting (or manually installing software) Android devices. If you don't follow the step-by-step installation process properly, chances are your smartphone will malfunction. International Business Times, India Edition is not responsible for damages and complaints from readers if what you receive does not match the expected result, or if the smartphone becomes defective. Therefore, we advise users to get down to business with extreme caution. ]

I'll start with a short introduction. To date Android OS is the most popular operating system for mobile devices. Everyone loves her for her simplicity, openness and, of course, customization. However, many of us are getting bored with naked android, we go to the Internet and type "Download custom firmware for XXX phone." And what do we see? If you have a cheap Chinese smartphone, then you are unlikely to find anything, but if you do, it will be a converted stock. My own series of articles is dedicated to the owners of top-end devices, which are also popular among developers. Thus, if you have a Nexus 5, One Plus One, SGS 5, or another popular smartphone in your hands, you will get a bunch of answers when you google it. You can see names like cyanogenmod, paranoid android, aicp and others. But what do they tell us? In general, if you think about it, then nothing. We need some advice, some kind of review. That is why I set out to write this series of articles. With a periodicity of 2-3 days, I will review the popular and not very firmwares that are available for most smartphones.

So, let's begin. I hope you enjoy it. And first in line ... (Drum roll).

Cyanogenmod 12.1

Sai-en-ou-jen-mod, in the common people - CYANOGEN... The most popular custom firmware today. Installed on 12 million devices as of June 2014 (thanks to Wikipedia).
What is it about this firmware? Why is she so popular? It's simple. Cyanogenmod is not only a well-known brand that everyone knows, in short, Cyanogenmod is stability, wide customization functionality, its own theme engine, regular updates, a large team and, what is important, the WIDE wide range of supported devices.

Appearance and functions

So what exactly is cyan? Suppose we downloaded it, installed it, installed GAPPS, configured it as is usually done, nothing special. We wait for the main screen to load and see a regular desktop. Android Lollipop, which is no different from stock.

This may disappoint someone, but I will say right away, I will show you all the charms of the firmware further. Now it's time to open the notification shade.

At first glance, we see an ordinary curtain, but the weather forecast in it immediately catches the eye. A useful feature that doesn't eat up a lot of charge.
Let's go further. We go into the settings, here all the fun begins. Cyanogenmod has the widest range of settings. Below you can see screenshots of all. Then I will reveal the contents of those that deserve special attention.

Scrolling through the list of settings, items such as System Profiles, Status Bar, Notification Panel, Privacy, Buttons, Lock Screen, and Performance.

Performance

Let's start with performance, here we can choose the operating mode of our device, this is either normal, that is, universal, for everything, or energy saving, which is useful when you are on a long journey or use the phone as a dialer and high performance if you play games. The mode switch can be taken out into the shutter, but more on that later.

Updates

The next feature that I really like in this firmware is the possibility of OTA updates, it's convenient, you don't have to go to the site every time to download the update, the phone does everything for you. In total, you need to go to the "About phone" item and select "Updates". For convenience, you can set the frequency of automatic updates, which is very convenient.

Sound settings

Going into the sound settings, we see such a useful function as setting the power of the vibrator. Very useful when you have thick winter pants or need a vibrating alarm. Separately, you can configure alert modes, set a schedule, when and which one to include. Turn vibration feedback on and off, set the ringer volume to increase, change the ringtone and notification sounds.

Screen and display settings

In the screen and display settings, you should pay special attention to the Live Display, Hibernation Prohibition, Display Settings and Extended Screen. The first makes it more convenient to use the smartphone at different times of the day, when using the second, if, for example, you received an SMS, then the phone itself will unlock if you pick it up, the extended screen allows you to hide the soft keys and display settings adjust the notifications by the LED if you have one available. DPI change is also a useful feature, thanks to which you can make the controls on your phone smaller or larger, whichever suits you best.

Topics

The item "Topics" deserves special attention. Many people put themselves Cyanogenmod because of the cool engine. Here you can download the themes you need from Google Play, the site and other sites, choose the element you like from each one and make your phone unique. Almost everything can be changed.

Notification settings

And here are the notification settings, I won't say anything, from the screenshot everything is clear.

Button settings

I will consider in more detail the settings item called Buttons. You can change their location, adjust the switching of tracks with the volume buttons, change the navigation ring shortcuts (you need to hold down the "Home" key and swipe up) and much more.

Status bar settings

In the settings for the status sink, we can change the location of the clock, I personally like the center, change the battery style, display the percentages inside the battery, and a couple more interesting buns.

Notification panel

The notification panel settings allow you to turn the weather display on or off, get quick access to the switches, and change the switches themselves. You can see a list of all the switches in the screenshots, since it takes a long time to list them.

The firmware is very stable, it works faster than the drain, without jams, nothing crashes

Updates

If you are a simple user, then I do not recommend putting you "night builds" as they are sometimes unstable, in the update settings you can select Snapshot updates, they are not released every week and not every month, but they are suitable for an ordinary user.

Firmware features

• There are CAF assemblies for devices based on Qualcomm processors, they have significantly improved sound quality, camera speed and hardware in general
• Having your own, pretty good file manager
• Out of the box comes its own music player with a highly customizable equalizer (which doesn't always work)
• Music visualization on the lock screen
• Customizable Trebuchet launcher. Here you can customize the appearance and speed of transition animations, desktop grid size and various service gestures.

Minuses

• Kosyachny night assemblies, but that is why they are night
• Few custom cores for devices based on Qualcomm processors (CAF assemblies)
• It takes a long time to switch to the next (major) version of Android
• The stock equalizer does not always work

Well, I'm a little tired of something, but I seem to have described it in sufficient detail. So that's all, my friends. Thank you for your attention and time spent :-)

It is common in the world to compare Android and iOS. The main difference is the attitude towards the openness of the system for the user. If iOS does not even allow viewing individual folders on the device, then in Android the file system is available to the user. However, only at first glance it seems that Android developers are allowed to do anything with their OS: many important and necessary functions remain unavailable. Therefore, CyanogenMod firmware has become popular among advanced users. How to install, update and, if necessary, remove the firmware, read our article.

What is CyanogenMod?

CyanogenMod is an alternative Android firmware that expands the functionality of the operating system. The firmware has gained popularity: as of 2016, CyanogenMod is installed on 14 million devices.

It all started with the fact that a simple programmer Stephen Kondyk posted on xda-developers.com, the largest site with custom firmware for Android, his development for the HTC Dream smartphone. He did not think about the name for a long time and took his nickname - Cyanogen, adding Mod to it. Stephen Kondyk did not expect that someone would be interested in his development, but already in the early days, users responded positively about the firmware. Then the programmer, in a creative impulse, worked hard to finalize CyanogenMod, posting several updates per day on xda-developers.com.

Then Stephen Kondik posted CyanogenMod on Github, a collaborative development service. Then other programmers joined in the improvement of the project, who brought their ideas and developments. Over time, it became clear that CyanogenMod had evolved from a hobbyist firmware to an exceptional project. CyanogenMod's capabilities made mobile devices more functional than any other firmware.

Benefits

Why did users love CyanogenMod so much?

1. High performance... CyanogenMod, thanks to its optimization, significantly improves the performance of the device. Both menus and heavy games run much faster and smoother on this firmware than on the standard one. As an example, consider the Nexus 4, which produces 15-16 thousand Antutu Benchmark points on standard firmware. After installing Cyanogen makes 21 thousand points. In addition, for advanced users, Cyanogen allows you to change the circuit of the processor, control its frequency at its discretion. There are five modes: Interactive - standard frequency distribution, increases when the screen is turned on; Ondemand - less productive, more energy efficient; Userspace - allows you to configure everything yourself; Powersave - minimum processor frequency, maximum power saving; Perfomance - maximum processor frequency, best performance, but high power consumption.
2. The only way to install a new version of Android for older devices. Few manufacturers support their devices even for 4-5 years, releasing Android firmware 5 and 6, so CyanogenMod is the only way to put Android Lollipop and Marshmallow on such devices. Cyanogen also allows you to get rid of the manufacturer's pre-installed firmware, for example, TouchWiz from Samsung.
3. Customizable appearance... CyanogenMod gives you the ability to customize the design of every detail of the interface. PlayMarket has thousands of custom theme options. The firmware also supports the original Android theme (Android Holo up to version 12 and Google Material Design in versions 12 and 13), unlike the official firmware of device manufacturers.
4. System openness... The standard Android firmware has various restrictions for users. CyanogenMod does not have these restrictions, thanks to which there is a codec for the Free Lossless Audio Codec, a compressed cache, a large list of APNs, an OpenVPN client and a reboot menu. However, this is an advantage only for knowledgeable and able people, because the device can be accidentally broken.

Firmware versions

The latest version of CyanogenMod is the 13th, based on Android 6.0 Marshmallow. Each new version of CyanogenMod is developed to update Android. In addition, the developers maintain and constantly update all versions at the same time, releasing new builds of the project. There are six types of CyanogenMod assemblies:

1. Experimental - Experimental firmware versions for testing new ideas. These versions are extremely unstable, have an abundance of bugs and are only needed by developers for tests.
2. Nightly - daily updates, the result of the day's work of programmers. Like Experimental, they exist only for developers, so that enthusiasts can follow the development of the project and help it with new ideas and suggestions.
3. Millie stone is a raw version that collects all the innovations to test their interaction.
4. Snapshot is an already worked out assembly suitable for use. Usually, not all bugs have been caught and not all bugs have been fixed.
5. Release Candidaty (RC) is an almost finished firmware version. The developers check for bugs, performance and stability for the last time.
6. Stable is the final, stable release of CyanogenMod.

If you are a simple user who wants to install CyanogenMod, then you should choose the stable version of the firmware. This ensures that there are no errors and that it works. But for the sake of useful features that are not yet in the stable version, you can also try the developer versions. But such firmware is almost impossible to use - there are too many errors.

How to install: step by step instructions

Please note: installing CyanogenMod will void your warranty service!This applies not only to Cyanogen, but also to any other custom firmware. There are certain ways to hide traces of third-party firmware, but the methods are unreliable and do not always work. So if you're not ready to void your warranty, don't risk it.

Installing CyanogenMod is non-standard and difficult for untrained users: it has more than 10 steps. Updating the system is also not the most intuitive. Of course, there is an easy way to install the firmware, but this is far from the best option. The latest version of CyanogenMod is automatically downloaded, not always stable, as a result of which errors are possible. But since not everyone will want to spend time on a more complex method, we will analyze this option as well.

Easy installation

1. First, check if your device is supported. To do this, follow the link: http://wiki.cyanogenmod.org/w/CyanogenMod_Installer#Supported_Devices and see the list of supported devices.
2. In the smartphone settings, enable USB debugging (Accessibility -\u003e For Developers -\u003e USB Debugging).
3. Download the CyanogenModInstaller app on your smartphone from Google Play.
4. Download the dedicated Windows software (Vista / 7/8) to your computer: http://beta.download.cyanogenmod.org/install.
5. Turn on the app on your smartphone and follow the instructions in the program.
6. Connect your device to your computer via USB.
7. Turn on the program on your computer.
8. The program itself will start downloading the files required for the firmware. When everything is loaded, you will see the message “Everything is ready”.
9. Click on the "Install" button.
10. When the installation of the firmware is completed, the program will notify you about this with the message "Installation complete".
11. Done.

The hard way

1. First you need to get Root rights (remove restrictions imposed by Android developers). We will do this using the Framaroot program. Download Framaroot 1.9.1 from the Internet, install it and run it. If the antivirus displays a warning, click "Allow".
2. Now you need to unlock the Android bootloader. The best way to do this is with BootUnlocker. You can download the application directly from Google Play. Run the program and click the "Unlock" button. The bootloader will be unlocked.
3. You need to install Custom Recovery. Let's analyze its installation using the example of TWRP (Team Win Recovery Project).
   
4. Let's start installing CyanogenMod.
   
5. Once the installation is complete, reboot the system. If everything went well, an empty desktop will open. If not, the phone won't boot. In this case, you need to enter Recovery mode again, install the firmware on a new one, but only turn on full Wipe.
6. The last thing left is to install Google Play. To do this, download the Gapps package (http://opengapps.org), move them to the root folder and install in the same way as the firmware itself, via Recovery.
7. Done!

Video: How to Install CyanogenMod Firmware?

Can CyanogenMod be installed on an unsupported device?

The answer is unequivocal: no. CyanogenMod Installer will simply write that your device is not supported. If installed manually, there can be a bunch of problems, up to the fact that the phone or tablet will stop working. If the firmware could run on the device, the developers would add it to their list anyway.

How to update the firmware

There are also two ways to update CyaongenMod.

The easy way

This method works for Cyanogen versions 10.0 and higher. Everything is extremely simple: open the settings, go to the "About phone" item, then "CyanogenMod update". The device will automatically download the latest update and install it. In the process, the smartphone will reboot several times. All data will be saved.

Manual option

Please note: Do not upgrade your device to more than one version of CyanogenMod at a time (for example, from CM 10.0 to 10.2). Unpredictable errors and incorrect operation of the firmware may appear. It is also not recommended to roll back the device to earlier CM versions (for example, from 10.2 to 10.1). Sometimes it leads to an error with an endless reboot of the smartphone. For any downgrade, you must first make Wipe Data / Factory Reset.

It is almost always best to use the easy update method, as it is less likely to do something wrong. However, if your Cyanogen version is lower than the tenth version, as well as if you use third-party add-ons (add-ons), you will have to use a complicated method, since the standard update does not allow you to immediately install the add-ons to the firmware.

1. First, download the latest stable (or whichever version of CyanogenMod you need) and the latest version of the Gapps package.
2. Turn on Recovery mode.
3. Install the firmware first, then the zip archive with Gapps, and then third-party addons. There is no need to do Wape, so all data is retained when updated.
4. Done.

When you update again, there is no need to reinstall Gapps, since the data is saved, but add-ons will have to be installed manually.

In addition, only with a complex version, you can choose which update to install (which cannot be done with a simple installation method).

How to remove if necessary

If you decide to return everything as it was, you need to reinstall the firmware again, but this time replace CyanogenMod with the stock firmware of your device manufacturer. You can download this firmware from the manufacturer's official website.

1. When you download the firmware, save the archive in the root directory of the device
2. Turn on the Recovery mode (hold down the power button and the volume up button while starting the device).
3. Check all Wipe checkboxes. Please note that all data will be deleted.
4. Then install the downloaded archive with the official firmware.
5. Wait for the installation to complete.
6. Reboot your device.
7. Done.

Sometimes a return to the native firmware of the device erases all traces of the presence of CyanogenMod, in which case the warranty is not nullified. However, you should not count on this, as it depends on the luck and carelessness of the support staff. The rules for the provision of warranty service prohibit changing the manufacturer's firmware.

CyanogenMod is an interesting firmware that has grown from an amateur handicraft to a serious and ambitious project, which has no analogue in the world. CM allows you to do with the device what no official firmware allows. But it should only be installed by advanced and knowledgeable users, since open systems are unsafe. In addition, the phone may fail and warranty service will not be available. However, if you lack the standard functions of a smartphone or tablet on stock Android firmware, if you are ready to learn and develop, if you are ready to spend time and effort overcoming errors that arise, then you definitely need to flash your device with CyanogenMod. According to some users, CyanogenMod is the culmination of mobile development.
