How to completely remove the system on a Huawei smartphone: all methods of resetting and flashing

Removing the operating system on smartphones Huawei is a procedure that may be needed in a variety of situations: from preparing a device for sale to dealing with software glitches or viruses. However, the term “wipe the system” is often understood differently: some mean full factory reset (Hard Reset), some mean deleting user data while preserving the firmware, and some really want erase Android completelyto install custom firmware or another version of EMUI. In this article, we will analyze all possible scenarios, including official and unofficial methods, and also talk about the risks and consequences of each approach.

It is important to understand that Huawei since 2019, it has been actively limiting the ability of users to modifications to your devices. Unlocking the bootloader (bootloader) on new models is officially prohibited, and the use of uncertified software can lead to loss of warranty or even to a “brick” (turning the phone into a “brick”). Therefore, before any manipulations with the system be sure to create a backup copy of the data and check the compatibility of the selected method with your model.

If your goal is to simply return the phone to factory settings, the standard Hard Reset through the recovery menu is sufficient. If you want to install custom firmware (for example, LineageOS or GrapheneOS), you will have to unlock the bootloader and use tools like Fastboot or Huawei Multi-Tool. Below we will analyze each of these methods in detail, and also tell you how to avoid common mistakes.

1. Preparing to reset or remove the system

Before you begin any manipulations with the system, you must complete several critical steps. Neglecting them can lead to data loss, the inability to restore the phone or even physical damage to the device.

The first thing to do is save all important data. Even if you plan to simply reset the settings, a mistake in the process could result in the internal memory being completely erased. Use cloud services (Huawei Cloud, Google Drive), local copying to a PC or external drive. Pay special attention to:

• 📱 Contacts (export in format .vcf)
• 📸 Photos and videos (check folders DCIM and Pictures)
• 🔑 Passwords and application data (use Huawei Backup or Titanium Backup for rooted devices)
• 📄 Documents and downloads (folder Download often contains important files)

Second - make sure the battery is charged. The reset or flashing process can take from 10 minutes to several hours. If the phone runs out of power during the process, it is almost guaranteed to fail. The optimal charge level is at least 70-80%. If the battery is worn out (capacity below 80% of the nominal), connect the device to the charger via the original cable.

⚠️ Attention: On some models Huawei (for example, P40 Pro, Mate 40) after resetting it may you will be required to enter your account password Huawei ID, even if you have not used it. If you do not remember your login details, unlocking the phone will become impossible without contacting the service center. Check the linked email and phone number in advance.

2. Method 1: Hard Reset via the recovery menu

The safest and manufacturer-recommended way to return the phone to factory settings is Hard Reset via Recovery Mode. This method does not require unlocking the bootloader and is suitable for most models Huaweiincluding P30, Mate 20, Nova 7 and newer devices. However, it does not delete the firmwareonly erases user data and settings.

To perform a Hard Reset:

1. Turn off the phone.
2. Hold the combination buttons:
   • For most models: Volume up + Power (hold for 10-15 seconds).
   • For Huawei P50 and newer: Volume Up + Volume Down + Power.

When the logo appears Huaweirelease the Power button but continue to hold the Volume button until the menu opens eRecovery.

Select item Wipe data/factory reset (use Volume buttons to navigate and Power button to confirmation).

Confirm the action by selecting Yes.

After the process is completed, select Reboot system now.

The whole process will take about 5-10 minutes. After rebooting, the phone will be in the same state as when it was first unpacked - you will need to re-set the language, connect to Wi-Fi and log in to your accounts.

⚠️ Attention: On devices with EMUI 12 and newer after Hard Reset, protection may work Factory Reset Protection (FRP). If you do not remember the account details Huawei or Googlelinked to the phone, it will be extremely difficult to unlock it. In some cases, official unlocking through a service center will be required.

3. Method 2: Reset through phone settings

If the phone turns on and you can log into the system, the easiest way is to reset it directly from the settings menu. This method is identical to Hard Reset, but is more convenient because it does not require memorizing button combinations. Suitable for all models Huaweiincluding Honor (before brand separation).

Instructions:

1. Open Settings (gear icon on the main screen).
2. Go to section System and updates → Reset.
3. Select Reset settings (or Restore and reset on older versions EMUI).
4. Tick the checkbox Delete all data (you can optionally select Clear memory cardif it is installed).
5. Enter the screen lock PIN or password (if installed).
6. Confirm the action by clicking Reset phone.

The process will take a few minutes, after which the phone will automatically reboot. This method does not delete the firmwarebut only returns the settings to the factory settings. All installed applications, accounts and files will be erased.

💡

If after resetting the phone takes a long time to boot (more than 15 minutes), do not panic. The first boot after a Hard Reset may take up to 30 minutes - this is normal. Do not turn off the device or remove the battery (if it is removable).

4. Method 3: Removing the system via Fastboot (for advanced users)

If you want completely erasing the firmware (for example, to install a custom or another version of EMUI), you will need to use the Fastbootmode. This method is only suitable for users with experience with ADB i Fastbootas incorrect actions can lead to irreversible damage to the device.

Before you start, make sure that:

• 🔓 On your model Huawei it is possible to unlock the bootloader (on new devices this is often blocked by the manufacturer).
• 💻 You have installed drivers Huawei HiSuite i ADB/Fastboot on PC.
• 📥 Downloaded official or custom firmware in format .img or .zip.
• 🔋 The battery is 100% charged.

The process of removing the system via Fastboot:

1. Connect your phone to the PC via a USB cable.
2. Hold Volume down + Powerto enter the mode Fastboot.
3. On the PC, open the command line (cmd) and check the device connection with the command:

   fastboot devices

   If the phone is detected, you will see its serial number.

4. Unlock the bootloader (if possible for your model):

   fastboot oem unlock [your_unlock_code]

   Note: The unlock code can be obtained on the official website Huawei (for older models) or through unofficial services (for new ones).
5. Delete the current system partitions (attention, this will destroy all data!):

   fastboot erase system
   fastboot erase boot
   fastboot erase recovery
   fastboot erase userdata

6. Install new firmware (if required):

   fastboot flash system system.img
   fastboot flash boot boot.img
   fastboot flash recovery recovery.img

7. Reboot the device:

   fastboot reboot

What will happen if you interrupt the firmware process?

If you disconnect the phone from the PC or turn it off during flashing via Fastboot, there is a high risk of damaging the boot partitions. At best, the phone will not turn on and will need to be re-flashed. At worst, the device will turn into a “brick” (not. will respond to buttons and charging), and can only be restored in a service center using special equipment (for example, Huawei Multi-Tool or DC-Phoenix).

⚠️ Attention: Starting with EMUI 10 and later, Huawei blocks the ability to unlock the bootloader on most models. An attempt to bypass this blocking is unofficial methods can lead to loss of IMEI, refusal of warranty service or even hardware damage to the communication module. Before experiments, check the compatibility of your model on the forums XDA Developers or 4PDA.

5. Method 4: Using Huawei Multi-Tool (for advanced users)

Huawei Multi-Tool is specialized software that allows you to perform low-level operations with the firmware, including completely erasing the system, unlocking the bootloader and recovering from crashes. The tool supports most models Huawei and Honor, but requires. caution in use.
