If the update process does not start, you need to open the calculator, enter ()()2846579()()= and then select Project Menu Act -> Upgrade ->SD Card upgrade.

Attention!

• Do not remove the card or press the power button until the process is complete and the appropriate prompt appears on the screen;
• If the power is lost during the installation process, repeat the firmware process;
• After copying the firmware to the SD card, check if it is damaged (copy the firmware files, disconnect and then connect the SD card, check that the *.zip files in the firmware open without errors on the computer).
• Delete the firmware file from the SD card or rename the dload folder if you don’t want to accidentally update your tablet again!

Backup

The main rule of any gamer or programmer is “SAVE!!!” And in our case, this rule has the same importance.

Has the function of creating a backup copy and saving it to your Google account. But in this case, you can only save contacts. Therefore, it is necessary to acquire the necessary software. 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 will 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.

Importance of rollback

Sometimes, changes may affect the OS not only in the area of ​​its functionality, but also in its design in a visual format. There are applications that could be used in previous versions of the OS, but they do not provide support. The utility that was actively used on the previous OS may be inappropriate for the next use.

In this case, it would be more appropriate to abandon it until there is an official version of the update for the program. If the user updates the OS, but for various reasons he does not like the changes, then he will need to do a system rollback and remove the new software environment.

In the article we will dwell in detail on how you can return the old OS after updating Android. We will use the Nexus 5 smartphone as an example. But this option is also suitable for Honor or Samsung, since all of these brands are officially supported by Google.

Please note that when performing this procedure, you risk losing important data, as it will need to be deleted. We advise you to make a couple of backup copies of data on your smartphone. Flashing the system will result in complete destruction. Those. you act at your own risk.

Please note that the following steps may result in the breakdown of the mobile gadget; it will be impossible to restore it if the firmware fails.

How to fix “software install failed” manually

Often the bug Software install failed! appears when updating Huawei devices manually. This result is often caused by cases where the gadget in standard mode does not notice the update, and the owner of the smartphone wants to switch to updated versions of the software.

1. Download the desired update to your PC from official sources. There are many developers, one of the recommended ones is 4PDA — make your decision yourself. Archive volume is 2-5 GB.
2. Create a “dload” folder and extract the UPDATE file into it. APP. Please note that there is often a downloaded directory with the necessary content, so it is available for extraction in its entirety.
3. Check on your PC that the elements in the folder are available for opening and launching.
4. Connect your Huawei smartphone via USB cable to your laptop or PC. Then drop the dload folder with all the files into the root of the smartphone’s SD memory.
5. Disconnect from the computer and turn off the gadget.
6. Press the volume buttons and the power button of the device at the same time. After 5-10 seconds of holding these keys, the smartphone will launch a forced update and flashing.

If these steps are performed correctly, if the error persists, check the following nuances:

From Android 6.0 onwards, the creators of the Huawei brand no longer give chances for updates via SD card and have stopped producing standard packages. If you have Android 4.2 or 4.4, then the best thing to do is download the official update to version 5, and then update over the air. Or pay attention to updates to standard firmware.

The main cause of errors in Huawei brand smartphones is an archive with broken files or inaccuracies when the user creates the dload folder on his gadget. To fix it, the best way is to perform all the steps again after checking the correctness of the downloaded archive.

How to unlock your phone with a fingerprint

Don’t forget: almost all modern Huawei and Honor smartphones are equipped with a fingerprint scanner. Not only is this a more reliable method of protection, but it also does not require memorizing a combination of characters or a sequence of dots from a pattern.

To install your fingerprint you need:

1. Open phone settings.
2. Go to the “Security and Privacy” section.
3. Click on “Unlock by fingerprint”.
4. Register one or more fingers of your hand.

The fingerprint scanner is a reliable thing, but sometimes it fails. It’s good if this is a one-time occurrence, but some users cannot unlock Huawei for a long time and literally fall into despair. Especially for such situations, developers, in parallel with the fingerprint, are required to ask the owner to set a password. It will help restore access to the device if the smartphone for some reason cannot recognize your finger.

The password is set along with the fingerprint. Therefore, when another person’s finger approaches the scanner or the sensor simply does not recognize it, the user can enter a digital code. But, if you pick up someone else’s smartphone with fingerprint protection, don’t even try to unlock it. You will only be wasting your time.

In order for the scanner to recognize the fingerprint without any problems, you only need to touch it with a dry and clean finger. It is also recommended to register multiple fingerprints at once.

More information about firmware versions:

So, let’s take a look at the firmware numbering of Huawei smartphones. For example, let’s take the firmware from Huawei Ascend Mate — MT1-U06 V100R001C00B907.

As you probably guessed, MT1-U06 is the name of the device. M T1 is the main base, that is, Huawei Mate, U06 is a revision of the device. Devices come in different revisions, in this post I will not go into details of their designation, I will only say that the letter U is UMTS (regular 3G), and the letter C is the CDMA version. Devices with revision MT1-U06 are supplied to Russia.

CxxBxxxSPxx — This is the most important option in the firmware, it shows on which version of the “base” the firmware is compiled Bxxx — the numerical class of the base for the SPxx firmware — Service Pack number. The higher Bxxx and SPxx, the newer the firmware. (Bxxx has higher priority than SPxx). Cxx is a region of the country.

Next, let’s look at the firmware version itself — V100R001C00B907. V100 and R001 are the main version and firmware revision. They change in very rare cases, when there is a big change compared to the previous firmware version (for example, the transition from Android 2.x to 4.x). Even within Android 4.x versions, these values ​​usually do not change.

C00B907 — for most new devices, the value of C00 no longer changes, and in general it means binding to the region. Now the region can be determined in the “Special version” menu item — CUSTC10B907.

So, for smartphones, the Russia region (channel/ru) is CUSTC10. The binding to the region can easily be changed with a special firmware file; in some official firmware there is an update.app file in the cust folder weighing several megabytes or kilobytes, which changes the region to Russia.

B907 — the firmware version itself. I think there is no need to explain that the higher it is, the newer the firmware.

View OS version using benchmarks

As mentioned above, before updating Android on a Huawei phone, you need to find out its firmware version. For this, there are also special applications that analyze the performance of the device, its power, conduct synthetic tests and, among other things, show all the information about the device under study.

1. The AnTuTu application is one of the most popular comprehensive benchmarks for Android. In order to find out the OS version on your device using this software, you need to go to the section “ Info
   «, where in the field » Basic information
   » All information about the operating system will be displayed. AnTuTu also examines the performance of the processor, RAM and other components;

2. In the Geekbench 4 program, which is also designed for Android performance analytics, you can find out the OS version by going to the “ CPU section
   «;
3. In the AIDA64 utility there is a tab “ Android
   «, which provides information about the system version;
4. In the CPU-Z application program, information about the Android operating system is located in the “ System section
   »

These programs are useful because, in addition to providing information about the operating system, they will help you find out the technical characteristics of the internal filling as a whole.

Reset Huawei using one click

Recently, Huawei series smartphone has gained great popularity in the market and has gained immense popularity among people. As for me, a few days ago, I just bought the latest Huawei smartphone, Huawei P9. Like all of us now, nowadays, to use smartphones safely, we usually tend to lock our phone screen with patterns, password and fingerprints, so other people cannot easily peek into our personal information stored in our phone memory.

Part 1: preparation — Huawei reset

https://www.youtube.com/watch?v=hb15ZlixZC8

You wouldn’t start cooking before you’ve cooked the meat, would you? The same rule applies to your phone. Before you learn how to restore that Huawei device, there are a few prerequisites that you should keep in mind. This is a basic list of things that will help you prepare your phone before actually resetting your Huawei phone.

1. Turn off your Huawei phone before resetting.
2. Make sure it has at least 70% battery life. Resetting your phone completely drains your battery, so to avoid any problems, you must charge your phone.
3. Performing a hard reset on your Huawei phone may take some time, but if you feel that it is taking too long and it is frozen, you need to remove the battery and wait for 10 seconds to reset the battery and restart the phone again. You should also ensure that your phone is not connected to a charger during this time.
4. Back up your phone.
5. Before resetting, try clearing cache data from your phone. This will speed up the entire reboot process.

Now, let’s move on to how you can reset your Huawei phone using three simple methods.

Via custom recovery

Another convenient option for rolling back Android is a custom TWRP flashing. Firstly, it is already installed on some smartphone models, and secondly, you can download it yourself. To do this, you do not need to obtain ROOT rights, but you only need ADB and Fastboot utilities, a PC and an unlocked bootloader on your phone.

Instructions:

1. Download the “Minimal ADB and Fastboot” package to your computer and install it, placing it in the selected directory.
2. On your smartphone, activate the “USB Debugging” option and connect it to your PC.
3. After checking compatibility, you need to download the TWRP Recovery image file to your computer, which is suitable specifically for this smartphone.
4. Next, go to the official website of the developer, find the model of the gadget you are flashing and complete the download.
5. Place the file (it’s better to call it twrp.img) in the folder with the ADB application.

Now everything is ready to install custom recovery. On the command line specify:

• first request “adb reboot bootloader” and activate execution with the “Enter” button;
• then “fastboot flash recovery twrp.img”.

After the process is completed, the smartphone will need to reboot and do the following.

• Download the archive with the firmware onto your PC, the files of which are immediately transferred to the memory card.
• Enter the “Recovery” menu by selecting one of the key combinations: “Volume (up or down) plus Power” or “Home” volume control power on.”
• Here you will first need to clear the file system, and then go to the archive and start the firmware installation process.

To complete, you will need to reboot your device again.

Step 2. Enter Download Mode on your Huawei phones

Three steps to enter download mode.

b. Simultaneously press and hold the Down button and the Power button.

p. Press the Volume Up button to enter Download Mode.

Step 3: Download the recovery package

  After entering the download mode, Huawei Data Recovery will start downloading the latest recovery package on your Huawei phone. This may take some time, please wait until it is completed.

Step 4: Remove phone lock screen without data loss.

You can allow Android lock screen to be removed when the recovery package download is completed. You don’t need to worry about your data, nothing will be lost during the process.

Once all the progress is completed, you will be comfortable accessing your Huawei phone without entering a password and viewing all your data on the device without restrictions.

Honestly speaking, after using Huawei Data Recovery, I believe it will be a good helper for you to unlock screen lock when you are unable to handle Huawei as well as other Android phones. This way, when you encounter the awkward situation described above, you don’t need to worry about it. Trust me, just try it.

Step 3: Download the recovery package

 After entering the download mode, Huawei Data Recovery will start downloading the latest recovery package on your Huawei phone. This may take some time, please wait until it is completed.

Step 4: Remove phone lock screen without data loss.

You can allow Android lock screen to be removed when the recovery package download is completed. You don’t need to worry about your data, nothing will be lost during the process.

Once all the progress is completed, you will be comfortable accessing your Huawei phone without entering a password and viewing all your data on the device without restrictions.

Honestly speaking, after using Huawei Data Recovery, I believe it will be a good helper for you to unlock screen lock when you are stuck on Huawei as well as other Android phones. This way, when you encounter the awkward situation described above, you don’t need to worry about it. Trust me, just try it.

Conclusion

In conclusion, I would like to examine one more concept that you will definitely come across while studying the forums. This is the concept of «brick». A “brick” is a device that, after returning from Lollipop to Kitkat, stopped working altogether. To prevent this from happening to your Android device, you need to approach the matter as carefully as possible and carefully study all aspects.

In the first case, there is nothing much to worry about, since, most likely, the cause of the trouble was a conflict in some applications or widgets and everything can be corrected by returning to the factory settings. If the smartphone still works, albeit with various “artifacts,” you can also fix this yourself.

In the third case, it is unlikely that you will be able to get by with “little loss” and you will have to either restore the smartphone through a computer using special software, or contact a service center or a familiar computer guru who knows how to restore Android after unsuccessful firmware.
