If your Xiaomi 14T is stuck in a bootloop, showing a blank screen, or giving an “Invalid IMEI” error, you’re not alone. These issues are common after a failed update, software corruption, or when experimenting with custom ROMs. The good news? You can fix most of these problems yourself using official firmware and tools.
This guide will walk you step-by-step through flashing the stock firmware, repairing IMEI, and restoring your Xiaomi 14T to factory condition.
🧠 What is Stock Firmware and Why It Matters
Stock firmware is the official operating system that comes pre-installed from Xiaomi. It’s essential because:
It ensures your phone boots up properly
Keeps your hardware (camera, modem, display) working
Brings security updates and optimizations
Can fix bugs, bootloops, or performance issues
If your phone is soft-bricked or showing network errors, flashing stock firmware is the safest fix.
🔧 When to Flash Firmware on Xiaomi 14T
Here are situations where flashing can solve your issue:
The phone is stuck on the MI logo (bootloop)
Software update failed and the phone is unresponsive
⚠️ Important: Bootloader must be unlocked. Use the Mi Unlock Tool and follow the instructions (it may require a 7-day wait period).
🚀 How to Flash Firmware on Xiaomi 14T (Step-by-Step)
🔹 Step 1: Download Official Firmware
Search for Xiaomi 14T Fastboot ROM
Choose the version that matches your region (Global, India, China, etc.)
📁 File format must end in .tgz — this is a Fastboot ROM, not a Recovery ROM.
🔹 Step 2: Install Xiaomi USB Drivers
Install Xiaomi or Qualcomm USB drivers so your phone is recognized in Fastboot mode.
Without drivers, Mi Flash Tool won’t detect your phone.
🔹 Step 3: Download and Launch Mi Flash Tool
Download Mi Flash Tool
Extract the archive
Run XiaoMiFlash.exe as Administrator
🔹 Step 4: Enter Fastboot Mode on Xiaomi 14T
Power off the phone completely
Hold Volume Down + Power together until you see the Fastboot logo
Connect the phone to your PC via USB cable
🔹 Step 5: Load Firmware into Mi Flash Tool
Click “Select” and browse to the extracted firmware folder
In the bottom bar, select “clean all” (recommended for a fresh install)
🔹 Step 6: Begin Flashing Process
Click the “Flash” button
Wait for 5–10 minutes for the flashing process to complete
Once successful, Mi Flash Tool will show “Success” in green
Your phone will reboot automatically into MIUI
✅ Congratulations — your Xiaomi 14T is now restored to stock firmware.
