How to update Android on Huawei P40 Pro

What you need to know before updating your smartphone firmware:

• Only FAT32 format cards can be used. Preferably less than 4 GB;
• The firmware must be located on the SD card in the dload folder;
• You cannot use the device’s built-in memory (except for those devices that do not have a Micro-SD slot);
• The file with the firmware should be called UPDATE. APP;
• During the firmware installation, the device will reboot several times – this is normal;
• If there are several folders in the archive with the firmware (step1, step 2, etc.), then flash all the files one by one.
• During a local firmware update, all data on the internal memory of your smartphone will be deleted!

Attention! Everything you do with your device is at your own peril and risk! No one guarantees the correct operation of the device during and after installing third-party firmware and/or other actions not provided by the manufacturer!

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!

What to do after installing updates

Once the process of flashing the device is successfully completed, you need to turn on the smartphone and check how stable it is. If everything is in order, you can restore the backup file.

In the case where the backup was uploaded via Google Drive, it is enough to log in on the phone using your Google account. The data will be restored automatically. If the backup file was placed in the memory of another device during updates, it must be transferred back to the mobile device.

When the backup is not restored automatically, you must perform the operation manually. You will need to open the settings, go to the “System” section and activate the backup download function.

Possible errors during updating and how to resolve them:

Q: When turned on with the volume buttons held down, the firmware process does not start. A: Try writing the firmware file to the dload folder again. If it still doesn’t start, try starting the update process through the settings menu.

Q: The device turned off and does not turn on. A: Wait a few minutes. If it doesn’t turn on, turn it on yourself, the process should continue normally.

Q: During the update, the process froze at some point and does not go further. A: Wait five to ten minutes. If the device continues to hang, remove and reinsert the battery. For devices with a non-removable battery, you need to press and hold (15 seconds) the power button and both volume buttons.

Manually via recovery mode

This option is similar to the previous method due to the fact that the firmware file must first be downloaded to the phone. But otherwise the process will be very different, since installation will require going to the engineering menu (Recovery Mode).

To go into recovery, you need to turn off the device and hold down the power button and the top volume rocker for a few seconds. If nothing happens, you should change the combination to the power button and the bottom rocker.

Provided that everything is done correctly, the recovery menu will light up on the screen. To navigate it, use the volume buttons, and confirm the action by pressing the power button.

You need to select “Reboot system now” if you want to update over the air. The “Apply update from ADB” parameter is responsible for installing the firmware from the internal storage, and the “Apply update from SD card” parameter is responsible for installing the firmware from the memory card. Having selected the appropriate item, all that remains is to confirm the operation and wait for the process to complete.

Manually via settings

This option is suitable for cases when the smartphone cannot find an update over the air. To install the latest firmware version, you will first need to download the installation file from the developer’s official website. After placing the zip file in the device memory, you need to perform the following steps:

1. Open phone settings.
2. Go to the system update section.
3. Click the button with three dots, and then click on the heading “Select firmware file”.
4. Specify the folder where the zip file was saved.
5. Confirm installation of updates.

The further process will not differ from the one presented earlier in the over-the-air updates. That is, the smartphone will reboot, and after installing the firmware it will be ready for use.

How to find out the current android version on Huawei p40 pro

Before installing updates, it is recommended to check the current firmware version. It is possible that the latest Android is already installed on your phone, and an update is not required.

To view the current version you need:

1. Open the smartphone settings.
2. Go to the “About phone” section.
3. Find the “Android Version” item.

This section will indicate the current firmware version. At the beginning of 2020, the current OS is Android 10, but very soon Google will release the next update to Android 11.

How can I find out the current firmware version?

To check the current software version, you need to go to Settings – About phone/About tablet – System update. The version is the three numbers after the letter B. For example, the build number V100R001C00B122 means that you have firmware version 122 installed. Any firmware with numbers greater than these is newer.

Local firmware update:

Local update is used if the innovations are large-scale; in addition, this method restores the system to its original form and, in most cases, eliminates the likelihood of problems with increased battery consumption in the first days after the update.

1. Create a dload folder in the root directory of the SD card.
2. Copy file UPDATE. APP from the archive with the firmware to the dload folder on the memory card.
3. Go to the Settings-Storage-Software Update menu and start the update process (Settings->Storage->Software Upgrade->SD card Upgrade->Confirm->Upgrade).

   “Install” button. When you press it, the device will reboot, install the update and turn on in normal mode. The service pack files will be deleted
   from memory automatically.

Please note that if the device has been elevated in rights (root), recovery is installed that is different from the original one, and the system has been modified using this elevation of rights, the update using this method will most likely end in an error and the phone After reboot it will turn on in normal mode.

Update with hisuite:

1. Download, install and update to the latest version the HiSuite program
   — a utility for synchronization, backup and much more from Huawei (contains ADB drivers).
2. To further flash the phone firmware, enable USB debugging in the phone settings in the developer section.
3. Launch the HiSuite program on your computer.
4. Connect the phone using a USB cable in HiSuite mode.
5. When you first connect, HiSuite begins installing drivers on your computer and Daemon on your phone. (a shortcut to the HiSuite program will appear on the phone – this tells us that the drivers have been installed successfully).
6. Select the EMUI ROM item in the HiSuite program.
7. If we DO NOT have a pre-downloaded firmware version, then select the Download ROM item, follow the link and download the required firmware version from the website.
   If we HAVE, or you have just downloaded it, a firmware version, then select the Loading ROM item, we will be prompted to select the location of the firmware file. We find the file and confirm the choice.
8. The file download process begins.
9. We are offered to save our phone data. Select the necessary backup items, if necessary, and confirm the selection. Or we refuse if we think that we already have saved data. After saving or refusing, select NEXT.

•  Wait for the firmware to finish.
• After flashing the HiSuite program, the phone will reboot and enter Recovery mode. A message will appear on the white screen indicating that the phone itself has started flashing the firmware.
• We wait for the successful completion of the firmware in the form of a tick. The phone will reboot itself.
• Turn off the phone and see a window on it about updating applications. We are waiting for the operation to complete.
• Go to the settings and in the update item we make sure of the version we have installed.

Tablet firmware update:

• Only FAT32 format cards can be used. Preferably less than 4 GB;
• The firmware must be located on the SD card in the dload folder;
• You cannot use the device’s built-in memory (except for those devices that do not have a Micro-SD slot);
• The file with the firmware should be called update.zip;
• During the firmware installation, the device will reboot several times – this is normal;
• If there are several folders in the archive with the firmware (step1, step 2, etc.), then flash all the files one by one.

Preparatory stage

Despite the fact that each subsequent firmware version brings a lot of new functions, after the update some smartphones are unstable. This happens when the user ignores the preparation step.

Before installing updates on Huawei P40 Pro, you need to meet 2 basic requirements:

And if everything is clear with the first point, then the second raises many questions for some people. Resetting to factory settings completely deletes files from the smartphone’s memory. This allows you to avoid errors when installing updates.

Of course, no one wants to lose personal data, so before resetting you need to create a backup:

1. Open settings.
2. Go to the “Storage and Backups” section.
3. Click on the Google Drive heading.
4. Activate the backup.

Performing these actions will result in the backup file being uploaded to cloud storage. After updating Android, it can be restored.

If there is not enough space on Google Drive to save all the data, it is recommended to create a backup copy through the “Copy and Restore” item. The resulting file should be moved to another device (for example, a computer) during the flashing process, and after the process is completed, return it back to the phone’s memory.

If the backup has been successfully created, you can safely proceed to restoring the phone to factory settings:

1. Launch the device settings.
2. Go to the “Backup and Reset” section.
3. Select “Reset settings”.
4. Click the “Reset Phone” button.
5. Confirm the operation.

Now you need to reboot your smartphone, and then go directly to the process of installing the new firmware.

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.

Forced local update via 3 buttons:

This firmware update mode is an emergency mode and will work even if the device does not boot normally.

1. Create a dload folder in the root directory of the SD card.
2. Copy file UPDATE. APP to the dload folder on the memory card.
3. Turn off your smartphone.
4. Press the Volume Up Volume Down keys and turn on the smartphone, while the Volume Up Volume Down keys should remain pressed for ~5 seconds after pressing the power button.
5. Wait for the update process to complete.

Methods to update android on Huawei p40 pro

The Android operating system can be updated in different ways. There are both classic and alternative options. It is recommended that you review the update methods in the order in which they are presented in this material.

Installing and updating firmware

Local update always deletes user-entered data and settings from the device memory. Before you start updating the software using this method, we recommend that you make a backup copy of all your important data through a backup application, as well as save other necessary information from the device’s memory (for example, to a memory card).

When updating online or FOTA, user data is saved. Despite this, we also recommend that you perform a backup before this update.

Before starting the procedure, make sure your device’s battery is charged to at least 60%.

To connect Huawei smartphones and tablets to a PC, you need the HiSuite utility. Install it on your PC before starting the update.
