How to return the old version of Android after updating – instructions

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 memory sections 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 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.

Hardware testing

This Huawei smartphone service menu offers extensive options for testing and configuring the phone’s basic hardware. In this engineering submenu, the user will have access to such items as:

1. Audio
   . Allows detailed configuration of sound playback parameters.
2. Camera.
   Adjust photo and video settings that are not included in the standard camera application.
3. Driving Current Camera
   . Reads current data from sensors in camera circuits.
4. CPU Stress Test
   . Conducting testing of all device processor subsystems.
5. Deep Idle Setting
   . Using this tab, you can disable the use of sleep mode when the device is in standby mode.
6. Sleep Mode Setting
   . Adjust sleep mode settings.
7. ChargeBattery.
   Detailed information about the battery and its charge.
8. Sensor.
   In this tab, the user can fine-tune the device’s sensor.
9. Multi-Touch
   . In this menu, you can check and adjust the number of simultaneous touch points of your screen.
10. Location Engineer Mode
    . Here the user can check the GPS module data.

That’s probably all, dear friends. We hope this article was useful to you and answered most of your questions. We wish you excellent setup of your phone, and may it bring you only pleasant emotions.

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 configure 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.

Backup

The most effective way to restore installed applications, system programs, settings and firmware is to roll back from a previously made Backup. Before making any changes to the software of your Android smartphone or tablet, you should always make backup copies.

This will completely protect you from unpleasant consequences. In general, creating backups is the golden rule not only when flashing Android devices, but also in any serious programming. If for some reason you did not follow the recommendations and began to change the firmware or make changes to the operating system without creating a backup copy before these procedures, then there is a way out.

There are many applications that are designed to create backup copies of your Android gadget, all of them have their own advantages and disadvantages. But we will look at the example of one of the first and most universal programs for backup and recovery – Titanium Backup.

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#

How to avoid problems in the future

Every person who has encountered a similar problem at least once will think about how to prevent its occurrence in the future. Therefore, we have prepared for you some important tips that will allow you to avoid, for example, data loss during recovery:

1. Write down passwords on a separate piece of paper.
2. Use the Smart Lock functions (fingerprint scanner, face recognition). These methods are more secure than a password and do not require you to remember any combinations.
3. Always make a backup to avoid losing files after a factory reset.

These 3 specific rules will help you forget about the problem of a forgotten password once and for all. If you follow at least one instruction, you will be able to get out of this situation with your head held high. At a minimum, you will not lose personal data, and at most, you will not be fooled by remembering new passwords, since you will use your fingerprint.

How to prevent your Huawei honor device from being locked – recommendations

Unlocking a smartphone after several attempts to enter the wrong password is a rather long procedure, although it is possible. Depending on the version of the operating system, your phone model and year of manufacture, the method of accessing the device also changes.

Be prepared to try almost every method and only a few will work.

1. To avoid such troubles, always remember or write down your login information first.
2. Try not to change the phone number or email address to which the device is linked.
3. Don’t make the pattern too difficult to reproduce.
4. Blocking can also occur due to system operations with the phone. For example, flashing, installing an unofficial shell, incorrectly obtaining root rights.

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, and also prevent the update from happening again by blocking it.

How to get to the engineering menu?

In order to get into the engineering menu of a phone based on the Android operating system, you need to enter a certain secret code in the phone dialing menu. Most often on Android devices you need to dial the combination *#*#3646633#*#*. This code is suitable for most Android smartphones, but sometimes developers can change it, for example, entering the Huawei engineering menu most often occurs using the codes *#*#2846579#*#* or *#*#2846579159#*#*.

Also, codes can very often change depending on the specific device model and the type of single-chip system used in it. Also, it often depends on the phone’s single-chip system whether the smartphone even has a built-in engineering menu or not.

The code should be applied immediately as soon as you enter it on the call screen, but on some phones you sometimes also need to press the call button for the code to work properly. It is also worth noting that the code must be entered and not copied, since otherwise it will not work.

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.

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.

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:
   1. The phone may display a forced update menu, and a message indicating that the software installation failed with a red exclamation mark may appear on the screen. The phone can also go into recovery mode after turning it on. If your phone displays an update menu, this does not indicate an update problem. Restart your phone and check if you can go to your phone’s home screen.
   2. If your phone still does not display the home screen, please backup your data and contact a Huawei authorized service center.

1. Open Settings
   , find and open the section Applications
   , click on the option Update
   or Software update
   and select . Then restart your phone. Make sure your internet connection is stable and re-download the update package.
2. If the problem is not solved, please back up your data and restore your phone to factory settings.

If the problem is not resolved, please save a backup copy of your data and take the device to an authorized Huawei service center.

Reset using hard reset

It is also possible to unlock your Huawei phone if you forgot the pattern key by resetting the system settings. This method is the toughest. After using it, you will not be able to save information that was previously stored on Honor media. In fact, after resetting using Hard Reset, you get the phone with the settings that were set in it by the manufacturer at the factory. To reset an Honor or Huawei gadget, follow the instructions below:

All that’s left to do is wait for the smartphone to completely reboot. This usually takes 5 to 10 minutes. In almost all cases this option is successful. Its main disadvantage for the user is that no files remain. If the gadget falls into the hands of criminals, then this is a clear plus.

Disadvantages of rolling back to factory settings:

• personal information is lost in its entirety;
• basic phone settings, sounds, wallpapers are reset;
• The phone book is completely erased.

Reset using gmail account

The easiest way to “reanimate” a smartphone without the help of strangers and service centers is to use your Google account. If the user suddenly forgot the password for Honor 8 and tried to enter an invalid key five times in a row, the line “Forgot the pattern key” will appear on the screen.

To restore the phone and return it to working condition, you need to click on this inscription. After this, you will need to enter your email address and account password. Remember that you should only enter the email to which the phone is linked, otherwise you may have problems unlocking it.

Now you need to choose an unlocking method. If you need to change your password, you should select the “Change pattern” option. Next, you will have to enter a new key, after which you will again have full access to your smartphone. For those who have forgotten not only the pattern key, but also the password for their Google account, there is another way to unlock your phone.

Method 1. best way to unlock huawei phone without password

Let’s start with the most optimal option – turning to a professional program for removing the screen lock password on Android devices – 4uKey for Android. This method, firstly, is characterized by highly effective results, that is, with the help of this program you can easily unlock your smartphone.

Why choose this program:

To learn how to remove password from Huawei phone using Tenorshare 4uKey for Android, please check the guide below.

Thus, the PIN code (password, pattern) set on the lock screen of your Huawei phone will be deleted, and you will be able to use your device again. If you have a backup copy of your data, you can easily restore important data back to your phone.

Phone stuck on logo screen after update

1. If your phone is stuck on the logo screen for a long time, charge it for 30 minutes or more, then try turning on the phone again.
2. If the phone does not turn on, press and hold the Power button for about 10 seconds to force the phone to restart.
3. If the phone goes into eRecovery mode when booting up, please select the reboot option to check if the phone can turn on correctly.
4. If the problem is not solved, please connect your phone to Wi-Fi network and use eRecovery mode to restore your phone system. Or restore your phone system using the HiSuite application
   .

If the problem is not resolved, please save a backup copy of your data and take the device to an authorized Huawei service center.

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, you will need to restart your smartphone 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 look at 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.
