Specialized Flashing Guide for Pop-up Camera Devices
- Pre-flash Preparation: Ensure your pop-up camera is fully retracted before beginning the flash process. Do not interrupt power during flashing as this may damage the mechanism.
- Bootloader Status: Check if your bootloader is unlocked. For Global/EEA/India variants, unlocking is required before flashing non-matching region ROMs.
- Enter Fastboot Mode: Power off your device, then hold Volume Down + Power buttons until the Fastboot logo appears.
- Driver Installation: Install Qualcomm USB drivers on your computer to ensure proper device detection.
- Flash Process:
- Extract the downloaded .tgz file twice to access the firmware folder
- Open Mi Flash Tool and browse to the extracted folder
- Select “Clean All” for a fresh installation (recommended for troubleshooting)
- Click “Flash” and wait approximately 5-8 minutes for completion
- Post-flash Test: After first boot, test the pop-up camera functionality through the camera app to ensure proper operation.
Frequently Asked Questions (FAQs)
Q1. My pop-up camera won’t extend or retract properly after a software update. Can flashing help?
Yes, this is often caused by corrupted camera firmware. Flashing the complete stock ROM typically recalibrates the pop-up mechanism and restores proper functionality.
Q2. Why is the Global ROM version older than the China ROM?
Xiaomi typically releases updates first for the China market, with Global variants receiving updates later after additional testing and localization. This is normal for Xiaomi devices.
Q3. Can I flash China ROM on my Global Mi 9T for earlier updates?
Yes, but you need an unlocked bootloader and may lose some Google services functionality. Additionally, certain network bands may not work optimally, and the pop-up camera calibration might differ.
Q4. My device has AMOLED burn-in issues. Will flashing help?
Flashing won’t fix physical screen burn-in, but it can help if the issue is software-related display calibration. Use dark mode and screen shift features to prevent further burn-in.
Device-Specific Troubleshooting
- Pop-up Camera Not Working: After flashing, perform a camera hardware test through the secret menu (*#*#6484#*#*) to calibrate the mechanism.
- Fingerprint Scanner Issues: Delete and re-register fingerprints after flashing, as firmware updates can affect biometric data.
- Always-on Display Malfunctions: The Mi 9T/K20 uses an AMOLED panel susceptible to burn-in. Flash the original ROM for your region to ensure proper display driver compatibility.
- Network Connectivity Problems: Ensure you flash the correct regional variant to maintain proper modem configuration and network band support.
