If your Xiaomi MIX Flip is stuck on the boot logo, misbehaving after an update, or showing “Invalid IMEI”, you can fix it yourself by flashing the correct firmware and restoring the original IMEI (on cellular-enabled variants).

📱 What Is Stock Firmware and Why You Might Need It

Stock firmware (ROM) is Xiaomi’s official system software. Flashing it helps with:

• Fixing bootloop, bricked devices, or black screens
• Rolling back from custom ROMs or Magisk root
• Restoring IMEI/SIM functionality
• Resolving software crashes or update failures
• Reverting to a stable version for better performance

🚨 When to Flash the Xiaomi MIX Flip

You should consider flashing if you experience:

• Phone stuck at MI logo / Fastboot screen
• Apps crashing or OS lagging heavily
• Downgrading to a previous MIUI version
• Invalid IMEI, No SIM, or No Network
• Switching back to stock from custom ROM or root

✅ Requirements Before Flashing

Before you begin:

• ✅ Official Fastboot ROM (.tgz) for Xiaomi MIX Flip
• ✅ Mi Flash Tool (latest version)
• ✅ Xiaomi USB Drivers
• ✅ A Windows PC + USB-C cable
• ✅ Unlocked bootloader (use Mi Unlock Tool)
• ✅ Backup your data (flashing wipes all user data)
