Download the 2.1 GB Global ROM for Mi 5X (tiffany) and flash it without unlocking the bootloader. This guide details the “No Auth” EDL mode process.

Flash Global ROM on Mi 5X (tiffany) Without Bootloader Unlock

For users and technicians with a Mi 5X (codenamed “tiffany”), converting from a Chinese ROM to the Global ROM can be a challenge with a locked bootloader. This guide details the advanced “no auth” method. It allows you to flash the full Global ROM (2.1 GB file) using EDL mode, bypassing the need for an unlocked bootloader.

⚠️ Important Disclaimer: This is a High-Risk Procedure

This is an unofficial, high-risk procedure. It is intended for experienced users and repair technicians only. This method bypasses Xiaomi’s standard security. If you use the wrong file or perform a step incorrectly, you can permanently brick your device. Proceed at your own risk. We are not responsible for any damage.

Requirements: Tools & Files

You must have the correct drivers and specialized software to perform this flash. Standard flashing methods will not work.

• Mi 5X (tiffany) Global ROM: The 2.1GB Mi 5X [ tiffany ] [ NO NEED BL UNLOCK GLOBAL ROM].rar file.
• Auth Bypass Tool: This is the most critical part. The Snapdragon 625 chipset requires an authorization bypass. You must use a professional tool:
  • UMT Pro (Ultimate Multi Tool)
  • DFT Pro (Dongle Phor Tool)
  • UnlockTool or other similar software that supports the Mi 5X (tiffany).
• Mi Flash Tool: The official Xiaomi flashing software.
• PC & USB Cable: A Windows PC and a reliable USB Type-C cable.
• Qualcomm Drivers: Your PC must have the Qualcomm QDLoader 9008 drivers installed to detect the phone in EDL mode.

How to Flash (No Bootloader Unlock Method)

This process uses EDL Mode (Test Point) to force the flash.

1. Backup Your Data: This procedure will completely erase all data on the phone.
2. Install Drivers: Install the Qualcomm QDLoader 9008 drivers on your PC.
3. Enter EDL Mode (Test Point): Power off your Mi 5X. You must open the back cover and locate the two “Test Points” on the motherboard. Using metal tweezers, short these two points together and, while holding them, connect the USB cable to the PC.
4. Check Device Manager: If done correctly, your PC’s Device Manager will show a new device under “Ports (COM & LPT)” as “Qualcomm HS-USB QDLoader 9008”.
5. Bypass Auth: Open your professional tool (UMT, DFT Pro, UnlockTool). Navigate to the Xiaomi or Qualcomm section, select the “Mi 5X (tiffany)” model, and perform the “Auth Bypass” or “Disable Auth” function.
6. Open Mi Flash Tool: After the auth is bypassed, run the Mi Flash Tool.
7. Load the ROM: Click “Select” and choose the folder where you extracted the 2.1GB Global ROM file.
8. Refresh and Flash: Click “Refresh” in Mi Flash Tool. Your “COM” port should appear. At the bottom of the tool, select Go “clean all”. Do NOT select “clean all and lock.”
9. Click the “Flash” button and wait. The process will take several minutes to complete.
10. Reboot: Once Mi Flash Tool shows “Success,” disconnect the phone and hold the power button to boot it up. The first boot on the new Global ROM will take longer than usual.

Conclusion

By following this advanced method, you have successfully converted your Mi 5X (tiffany) to the Global ROM without needing to unlock the bootloader. Your phone will now have Google Play Services and multiple languages. This is only possible with professional tools to handle the auth bypass.
