Smartphone Poco X3 NFC became a real hit in its price segment, offering users high performance and excellent autonomy. However, the standard MIUI shell often limits the capabilities of the device, forcing enthusiasts to look for alternative solutions. This is where the famous forum comes to the rescue 4PDA, where the most complete knowledge base on modifying this gadget is collected.
Device owners often seek to expand functionality, remove ad blocks, or install a custom operating system to extend the life of the device. Modification process Xiaomi requires care, but opens access to hidden processor reserves Snapdragon 732G. In this article, we will look at the key aspects of working with the device, based on verified data from the community.
Beginner users may find it difficult to understand the abundance of terms, such as Fastboot, TWRP or Magisk. Don't be intimidated by abbreviations, as following instructions sequentially will minimize risks. The main thing is to strictly follow the algorithms described by experienced developers and not skip the preparatory stages.
⚠️ Attention: You perform all flashing actions at your own peril and risk. Incorrect manipulations can lead to loss of warranty or turn the phone into a “brick”.
Preparing a smartphone for modification
Before you begin any active actions, you need to properly configure the device itself. Without this stage, further steps will be impossible, since the security system Android blocks unauthorized access. The first step is to activate the developer mode, hidden in the depths of the menu.
To do this, go to Settings → About phone and quickly tap on the MIUI version seven times. Once the notification appears, return to the menu Additional → For developers. Here you are interested in two items: “USB Debugging” and “Factory Unlocking”. They need to be activated.
- 📱 Enable USB debugging to communicate with your computer.
- 🔓 Link your Mi account in the Factory Unlock menu.
- 💾 Make a complete backup of all important data.
It is important to understand that linking an account is not an instant process. After enabling the unlock feature, the system may require you to wait from 168 hours (7 days) to a month. Bypassing this wait through third-party services is possible, but carries additional security risks.
Write down the IMEI and serial number of the device before starting work. If there are problems with account activation, this information may be required to restore access through support.
Unlocking the bootloader
The key step on the path to complete freedom of action is unlocking the bootloader. Without this, you will not be able to install a custom recovery or gain superuser rights. The official tool for this procedure is called Mi Unlock Tool, and it is best to download it from the official website or a proven topic on w3bsit3-dns.com.
The process requires connecting the smartphone in mode Fastboot. To enter this mode, turn off the phone and hold down the volume minus and power buttons at the same time. A characteristic bunny with tools will appear on the screen. Connect your device to your PC via a quality USB cable.
fastboot devicesThis command on the command line (after installing the ADB drivers) should output the device serial number, which will confirm a successful connection. If the list is empty, check your drivers or cable. In the program Mi Unlock Click the "Unlock" button and wait for the process to complete, which will erase all data from the phone.
⚠️ Attention: After unlocking the bootloader, the Find My Device feature and some banking applications may no longer work normally without additional manipulations with SafetyNet.
☑️ Check before unlocking
Installing custom TWRP recovery
The standard recovery menu is limited in functionality, so enthusiasts are replacing it with TWRP (Team Win Recovery Project). This allows you to make full system backups, clean partitions and install modified firmware. For Poco X3 NFC (codename surya or karna) there are special assemblies.
Download the latest image twrp.img and place it in your ADB tools folder. Put your phone into Fastboot mode and run the flash temporary recovery command. It is important not to reboot the system immediately, otherwise the stock recovery will overwrite the changes.

After booting into the TWRP menu, the first thing to do is format the Data partition. This is a critical step for data encryption. On the menu Wipe select Format Data and enter yes. Only after this is the correct operation of the new system possible.
- 📂 Select the firmware file from the Install menu.
- 🧹 Execute Wipe Dalvik/Cache after installation.
- 🔄 Reboot the system using the Reboot System button.
If you plan to use custom firmware, then installing TWRP is a must. In case of returning to stock, you will need official firmware in the format fastboot and Mi Flash utility.
Obtaining Root rights through Magisk
Superuser rights provide access to system files, allowing you to remove uninstallable software, change fonts at the system level, and run powerful tweaking utilities. Today the gold standard is Magisk, which works system-free (systemless).
The procedure for obtaining rights to Poco X3 NFC usually involves patching the boot image. You need to extract the file boot.img from the firmware corresponding to your current software version. Then, through the Magisk application on your phone, select “Install” → “Select and patch file” and specify this image.
The resulting patched file is copied to the PC and flashed via Fastboot with the command:
fastboot flash boot_patched.imgAfter rebooting, Magisk will appear in the list of applications. If the status shows “Installed”, then everything was successful. Now you can install modules, hide root from banks, or run adblock at the system level.
What to do if Google Pay does not work after Root?
Use the MagiskHide Props Config module or Zygisk to hide the fact of system modification from applications with high security requirements.

Solving common problems and errors
During the modification process, users Poco X3 NFC often face a number of specific problems. One of the most common is a “black screen” after installing an inappropriate recovery. This can be treated by entering Recovery mode (pressing volume plus and power) and flashing the correct image.
Another common problem is NFC or camera not working after switching to custom. This can be solved by installing the correct drivers and firmware partitions. Sometimes it is necessary to reflash the modem or radio part separately via Fastboot.
- 🔋 Quick Discharge: Check background processes and wake-locks.
- 📶 Bad signal: reset the network settings or reflash the radio module.
- 🔄 Bootloop: go to TWRP and do Wipe Data/Cache.
If your phone keeps rebooting, don't panic. Go to Fastboot and try to flash the stock firmware via Mi Flash in mode clean all. This will return the device to its factory state.
⚠️ Attention: Don't try to flash the partitionpersistormodemfrom other models or regions. This can permanently damage communication modules and sensors.
Frequently asked questions (FAQ)
Will the warranty be reset after unlocking the bootloader?
Technically, unlocking the bootloader is a violation of the warranty in many regions. However, if you return the stock firmware and lock the bootloader back, it will be difficult to visually determine the interference if there is no physical damage.
Is it possible to update over the air (OTA) with custom firmware?
On most custom firmware, automatic updating does not work or does not work correctly. It is recommended to download new versions manually from the 4PDA forum and install them via TWRP to avoid system errors.
Is it safe to use banking apps with Root?
Without hiding settings (Magisk Hide / Zygisk) jars may not work. However, even with concealment there is a risk as detection systems are constantly being improved. For everyday use with banking applications, it is better to use a separate profile without superuser rights.
How to return completely to stock?
You need to download the official Fastboot firmware for your region, unpack it and flash it through the Mi Flash Tool in mode clean all. This will completely wipe the phone and return the bootloader to factory lock.
The most important thing when working with Poco X3 NFC is to always have the stock firmware and drivers on hand so that you can return to the original state at any time.
