How to Unbrick Poco X3 Pro via Fastboot Commands

The below instructions are listed under separate sections for ease of understanding. Make sure to follow in the exact same sequence as mentioned. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

STEP 1: Install Android SDK

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

STEP 2: Download Poco X3 Pro Fastboot ROM

Next up, download the Fastboot ROM for your device. As for this guide, I am using the following ROM file: POCO X3 Pro [vayu] V12.5.4.0.RJUINXM India Fastboot ROM. You are free to try any version of your choice, but it is recommended to try the newer builds only and more importantly, of your region.

Here is how to understand the Xiaomi Fastboot firmware version:

• V12.5.4.0– Firmware version
• R – Android version (R-> Android 11).
• JU – Smartphone model code (JU = Poco X3 Pro)
• IN – Firmware build type (IN for India | MI for Global | EU for Europe)
• XM – Firmware version code​

Furthermore, the downloaded firmware file might be in .gz format. So right-click on it, select Rename and change its extension to TGZ. Then reply Yes in the confirmation dialog box. Once that is done, you may extract this TGZ file via WinRAR/7ZIP, etc and proceed ahead to the next step to unbrick Poco X3 Pro via Fastboot Commands.

STEP 3: Move Poco X3 Pro Fastboot ROM Files to ADB Folder

1. Head over to the folder where you have extracted the firmware.
2. Then go to the Images folder present inside this extracted firmware and you should find the following files:
   
3. Select all these files via Ctrl+A shortcut keys and copy them to the platform-tools folder. This is the same folder that you have got after installing the Android SDK.
4. Once done, proceed to the next step to unbrick your Poco X3 Pro device via Fastboot Commands.

STEP 4: Boot Bootloop/Soft Bricked Poco X3 Pro to Fastboot Mode

1. First off, boot your device to the Fastboot Mode. For that, power it off.
2. If you cannot do so (due to your device being stuck in a bootloop) then the only option left is to let the entire battery drain out.
3. Once your device has turned off, press and hold the Volume Down and Power buttons for a few seconds. Then connect it to the charger at the very instance so that it gets some power to boot up to Fastboot Mode.
4. This will boot your device to Fastboot Mode. You should see the famous Mi Bunny Logo with the Fastboot text underneath it.
   

STEP 5: Unbrick Poco X3 Pro via Fastboot Commands

1. Let’s now start off with the fastboot commands and flash each of these partition files to your device.
2. For that, head over to the platform-tools folder where you have extracted the Fastboot ROM.
3. Go to its address bar, type in CMD, and hit Enter. This will launch the Command Prompt window.
   
4. Now execute the below commands in this CMD window. Don’t copy-paste them all at once, rather execute one command at a time. Furthermore, if any of the three fastboot erase commands given below gives out an error, then just leave them and move over to the next flashing command.

With this, we conclude the guide on how to unbrick Poco X3 Pro via Fastboot Commands. The best part about this tutorial is the fact that it doesn’t require any Poco X3 Pro Patched Firehose File (prog_emmc_firehose.mbn) or the prog_firehose_ddr_unbrick.elf file.
