How to return the previous Honor 7x update from version 9.1.0? | Questions |

In order to install any original firmware, you must do the following:

1. Copy the dload folder with all its contents to the root of the SD card;
2. Turn off the tablet;
3. Insert the SD card if it was removed;
4. While holding the Volume Up key, press and hold the Power button until the screen blinks. The Volume Up button must be held until the installation process begins (a green robot and a progress bar will appear);
5. Finally, when prompted, remove the SD card or hold the Power button for 10 seconds.

Note: In some cases, you don’t need to press the buttons at all and the process will start automatically after turning on/rebooting.

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!

Clockworkmod recovery

You can download the ClockworkMod Recovery program directly from the operating system using the ROM Manager application downloaded from Google Play. To install, select Flash ClockworkMod Recovery, to enter – Reboot into Recovery. As with Titanium Backup, the user needs root rights to work with this utility.

After entering the program, a menu appears with possible actions:

• Reboot system now – reboot the device.
• Install zip from sdcard – install a zip archive from a memory card.
• Wipe data/factory reset – return to factory settings.
• Wipe cache partition – clearing the cache.
• Backup and restore – creating backup copies and restoring them.
• Mounts and storage – connecting certain sections of memory and formatting them.
• Advanced – advanced features such as rebooting CWM, clearing dalvik cache, partitioning device memory, restoring system application rights to default and others.

The capabilities of ClockworkMod Recovery are much wider than those of the Titanium Backup application. This utility is perfect for confident users of Android devices, but beginners should be careful not to damage the gadget’s operating system.

Hard reset – or reset to factory settings

Important to remember: By doing a Hard Reset or factory reset of your smartphone, you delete all files and data from your Huawei or Honor smartphone and return it to its original state – just like immediately after purchase.

In order to reset your Huawei Honor and reset the password, do the following:

1. Turn off your device.
2. Now boot up while holding the Volume Up Power buttons
   together.
3. Release the buttons when you see the Huawei logo on the screen.
4. Now you will see the boot menu displayed on your screen.
   
5. Select “Wipe data factory reset”
   from the list of options using the Volume button to navigate and the Power button to select.
   
6. Then click “Delete all user data”.
   
7. That’s it! The device will automatically reboot to normal mode after the factory reset process is completed.

Smart look

Smart Look – additional ways to unlock the screen when entering a password is not required. Suitable for devices that can be configured to unlock using a photo, fingerprint and smart unlock. In this case, you won’t need to think about what to do if you forgot the alphabetic password: the smartphone will still be unlocked.

1. You can set up smart unlocking through Settings:
2. Open the “Security and Privacy” item.
3. To set up a fingerprint, click on “Fingerprint”.
4. To enable face unlocking, click on “Face Recognition”.
5. To unlock when connecting a Bluetooth device, click on “Lock Screen Password”, then go to the “Smart Unlock” tab and configure the device.

Huawei phones will require you to enter a password after rebooting the device, even if it has other unlocking methods installed, including fingerprint or face login.

Nuances and problems that may arise

Let’s consider the difficulties of each option, which in theory and in practice may arise when trying to unlock.

Is this always possible?

Modern electronic gadgets are very software-based. In many cases, the device is tailored for a specific version of the operating system. For example, if a laptop was sold with Windows 8 pre-installed, then with a high degree of probability you won’t be able to install “7” on it unless you replace the hard drive.

Not all users know about this, but even mobile components work with the help of drivers – in this regard, they are no different from PC components. To save money, processor manufacturers write drivers only for specific versions of the operating system. So it turns out that some Snapdragon 820 is simply not recognized by the old Android 4.2.

However, a rollback involves installing the version of the OS that was previously installed on the device. And manufacturers, it would seem, should not interfere with this. But it’s not that simple. Rolling back the system would be easy only if a copy of it was stored in the device’s memory.

But Android devices do not have such a function – the update completely erases all data about the old version of the operating system. This is due to the fact that there is not very much built-in memory in smartphones and tablets, and no one wants to occupy it with unnecessary load. That is why it is very difficult to rollback on Android; it is better not for an untrained user to do this.

You can use one of the following hidden features and tests by simply dialing the following codes:

1. Project menu *#*#2846579#*#*
   you can check things like: version information, network information, plywood information, etc.
2. Testing *#*#6130#*#*
3. *#*#0000#*#*
   About the phone
   
   
   
4. Calendar information *#*#225#*#*
   
   
   
   
5. Google Play Service *#*#426#*#*
6. IMEI *#06#

Correcting the situation

As practice shows, most often the cause of this condition is some kind of short-term failure. Therefore, you should initially make sure that your Wi-Fi Internet connection is of the highest quality.

For now, the effective solution to this issue is persistence to achieve results:

• Go to the Huawei eRecovery menu and activate the tool described above;
• Make sure that the access password is entered correctly;
• The download will begin, if it is interrupted by this error, reboot the smartphone and go to the same menu again;
• Almost always, the mobile phone starts downloading from the same place where the failure occurred. That is, if 67 percent had been downloaded before the error appeared, then the download will simply continue, and not again;
• After downloading, the installation process will begin. It can also be interrupted by another message – Update install failed;
• Do not panic, but initiate another reboot and start the same process;
• After this, the system will analyze the cause of the previously issued message and inform the smartphone owner that it is caused by damage to the Data section;
• You will be prompted to format it. Agree and wait for completion.

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 disable android update after flashing

Rolling back Android updates is not the last thing you should do. Since smartphones, as a rule, automatically update Android to the new version by default, all your actions can be canceled out by it in an instant.

That is, you will flash the firmware and return the previous version of Android, go to bed, and wake up the next day with the new version already installed.

To disable automatic Android updates you need:

1. Go to device settings;
2. Select “About phone”;
3. Go to “System Update”;
4. Go to update settings by clicking on the icon with 3 vertical dots;
5. And deactivate the automatic update function.
   

I hope the questions discussed helped you reset your Android update back to the previous version, as well as prevent the update from happening again by blocking it.

How to unlock your phone with your 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.

https://www.youtube.com/watch?v=Ig0PLWvbdqk

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.

Commands to access the menu

If you don’t know how to enter the engineering menu of a Huawei smartphone, or you can’t do it, then this is not a reason to be upset. Most Huawei devices support so-called “service codes”, which partially duplicate the functions of the engineering menu.

Service codes have been used in mobile phones for a very long time and many of them appeared long before the first Android smartphones came out. However, although such codes repeat some of the functions of the engineering menu, using them is not at all as convenient and completely unsafe.

Some of them can literally delete all data stored on the phone or disable certain functions of the device. So, if you are not one hundred percent sure what a particular code means, we do not recommend that you use it for the simple reason that they may interfere with the normal functioning of your phone.

Now let’s look at some examples of the most useful, in our opinion, engineering codes:

1. *#06#
   — using this code you can find out your IMEI address.
2. *#*#4636#*#*
   – This code provides you with some information about the phone, namely: device data, battery information, battery statistics and phone usage statistics.
3. *#*#7780#*#*
   – this code resets settings such as Google account data, system data and settings, downloaded applications to the factory state.
4. *2767*3855#
   — this code performs a complete formatting of the smartphone. So think twice before using it.
5. *#*#34971539#*#*
   — this code is intended to obtain information about the smartphone’s camera.
6. *#*#7594#*#*
   — used to change the on/off button modes.
7. *#*#273283*255*663282*#*#
   – Using this command, you can open the file copy screen and use it to backup your most valuable photos or audio recordings.

There are also many other service codes that allow you to very thoroughly check and configure your telephone. However, due to the fairly large number of them, this will perhaps be a topic for a separate article, and we will move on.

Rolling back updates in android 10

Information has appeared on the Internet that perhaps in Android 10 version it will be possible to roll back to the previous version in applications so that users can uninstall the latest updates even for those programs that are not system ones. But the information has not been confirmed, because this is not beneficial to anyone: program developers need people to use their latest versions with bugs fixed, Google Play needs fewer programs with errors and viruses, vulnerabilities to be distributed in the store, and users need the product to work correctly worked and was updated on time if bugs appeared.

As you can see, there are several ways to remove updates on your smartphone, but basically they are only suitable for standard products installed in the Android firmware. If, following our advice, you download old versions of programs from third-party resources, then be sure to check them for viruses, otherwise you can get an “infection” on your smartphone in a few clicks, after which you will have to take it to a service center to get rid of viruses or do a full reset.

Before you begin to solve the problem, please follow these steps.

1. Make sure your phone is not rooted. Otherwise, the phone will not receive HOTA Online Update notifications or the phone will not be able to be updated using HOTA Online Update.
2. Charge the phone so that there is enough battery power to turn on the phone. If the battery level is below 20%, the system cannot be updated. Fully charge your phone before updating.
3. Check whether a memory card is installed in your phone. If yes, remove it. HOTA update failure may occur due to incompatibility between the memory card and the phone. The list of supported memory cards may vary depending on the phone model.
4. Make sure there is enough free space on your phone’s internal memory or memory card. If there is not enough space, clear your memory card before updating.
5. Make sure that the update process is not interrupted manually. For example, the update process may be interrupted if you press and hold the power button for 10 seconds or more.
6. Check that the Power, Volume Up and Volume Down buttons work correctly and return to their original position when pressed. Also make sure there is no damage caused by contact with water. If you have one of these problems, follow these steps:

More information about firmware versions:

So, let’s take a look at the firmware numbering for 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 which version of the “base” the firmware is built on. 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.

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

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.

Telephony

One of the main points that catches your eye when you first enter the engineering menu of the Android Huawei smartphone is the telephony menu. In this menu you will have access to many useful settings, including such important items as:

1. Auto Answer
   . Here you will be able to enable or, conversely, disable auto answer to an incoming call.

2. Band Mode
   . Here you can manually select frequencies for the GSM module. This menu will show you all the frequencies your phone supports. You can uncheck those bands that your mobile operator does not provide, which will ultimately save your battery power.
3. CFU
   Setting
   . This option enables or disables conditional call forwarding.
4. AT Command Tool
   . A utility for developers that supports AT commands.
5. Modem Test
   . Fine-tuning compatibility with different types of devices.
6. Network Selecting
   . Here you can also select mobile communication standards (GSM, WCDMA, LTE). For greater energy savings, turn off those not in use.
7. NetworkInfo
   . A very convenient option for checking the quality of mobile operator services.
8. GPRS
   . Setting up mobile internet connections. A choice of active SIM card is also available.
9. HSPA Info
   . Information about the 3G network if this type of service is supported by your telecom operator.

10. Mobile data service preferred
    . Using this item, you can increase the priority of the Internet over voice traffic. However, be careful, as incoming calls in this case may sometimes not reach you.
11. Fast Dormancy
    . Allows you to save some of your phone’s energy on third generation networks.
12. RAT Mode (Phone Info
    ). Using this menu you can select the most used communication standard. However, use with caution, as these settings block the action of the Network Selecting item.
13. RF De-sense Test
    . Selecting a frequency range and a specific channel for testing communication quality.
14. SIM ME Lock
    . Makes it possible to configure the regional parameters of the GSM module in manual mode.

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 the 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 the device again.

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. Only after the whole picture of the planned actions is clear and understandable can you be sure of a successful result.

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.
