Learn the “No BL Unlock” method to install Global ROM on a locked Redmi 7A (pine). This guide covers the flash file, Mi Flash Tool, and EDL mode.

Flash Global ROM on Redmi 7A (pine) Without Bootloader Unlock

If you have a Redmi 7A (pine) with a locked bootloader and want to convert it from a Chinese ROM to the Global ROM, you’re in the right place. While the official method requires an unlocked bootloader, there is an advanced “no auth” method for technicians and experienced users. This guide explains the process and the files you need, specifically the Redmi 7A_pine_global_lock_bootloader.rar file.

⚠️ Disclaimer: Advanced Users Only

This is an unofficial, high-risk procedure. Flashing your device this way can permanently brick your phone if done incorrectly. This method bypasses Xiaomi’s standard security (Auth) and is intended for professional use. Proceed at your own risk. We are not responsible for any damage to your device.

Required Tools & Drivers

Before you begin, you must have all the correct software, drivers, and files. Using the wrong file for your device model will result in a hard brick.

• Redmi 7A (pine) Global ROM: The Redmi 7A_pine_global_lock_bootloader.rar file mentioned above.
• Mi Flash Tool: The official Xiaomi flashing software.
• Auth Bypass Tool: This is the most important part. You must use a professional tool that can bypass the Mi Authorization for the Snapdragon 439.
  • UMT Pro (Ultimate Multi Tool)
  • DFT Pro (Dongle Phor Tool)
  • Other tools supporting Qualcomm Auth Skip.
• PC & USB Cable: A Windows PC and a quality Micro USB cable.
• Qualcomm Drivers: Your PC must have the Qualcomm QDLoader 9008 drivers installed.

Flashing Process (No Bootloader Unlock)

This process uses EDL Mode, which is a low-level flashing mode for Qualcomm devices.

1. Backup Your Data: This process will completely erase all data.
2. Install Drivers: Ensure the Qualcomm QDLoader 9008 drivers are installed.
3. Enter EDL Mode (Test Point): Since the bootloader is locked, you must use the “Test Point” method. This requires opening the back cover of your Redmi 7A and shorting two specific test points on the motherboard while connecting the USB cable to the PC.
4. Bypass Auth: Once your PC detects the phone in Device Manager (as “COM port 9008”), open your auth bypass tool (UMT, DFT Pro, etc.). Use the tool’s Xiaomi/Qualcomm function to “Disable Auth” or “Bypass Auth.”
5. Open Mi Flash Tool: After bypassing auth, run Mi Flash Tool.
6. Load the ROM: Click “Select” and choose the folder where you extracted the Redmi 7A_pine_global ROM.
7. Refresh and Flash: Click “Refresh” in Mi Flash Tool. Your device should appear. At the bottom, select “clean all”. Never select “clean all and lock.”
8. Click “Flash” and wait for the process to complete. It may take several minutes.
9. Reboot: Once Mi Flash Tool shows “Success,” disconnect the phone and hold the power button to reboot. The first boot into the Global ROM will be slow.

Conclusion

You have successfully converted your Redmi 7A (pine) to Global ROM without unlocking the bootloader. This method is perfect for devices where bootloader unlocking is not an option, but it relies on professional tools like UMT or DFT Pro to bypass the auth security.
