Infinix Hot 30i X669C Official Signed Firmware Tested File

This guide provides verified instructions to flash the factory-signed firmware on the Infinix Hot 30i X669C. Learn how to use SP Flash Tool safely, preserve IMEI, and restore stock stability. Includes tested file details and troubleshooting tips.

Why Use Signed Firmware?

The X669C-H6127AgAhAxAyBcBdBeBfBg-S-GL-240717V1335 firmware is digitally signed by Infinix, ensuring authenticity and compatibility. Flashing this version:

• Fixes software bugs & bootloops
• Restores warranty eligibility
• Avoids malware risks from unofficial ROMs

Critical Files in the Firmware Package

The Factory Signed Firmware.rar includes:

• MTXXXX_Android_scatter.txt (MTK scatter file for SP Flash Tool)
• boot.img, recovery.img, vbmeta.img (Critical partitions)
• super.img (Merged system/vendor partitions)
• preloader.bin (Bootloader firmware)
• userdata.img (Factory data reset file)

Tools Required:

1. SP Flash Tool (v5.2208 recommended)
2. Tecno Flash Tool
3. USB Drivers: Install MediaTek USB Drivers.
4. 7-Zip (for RAR extraction)

Step-by-Step Flashing Instructions

Step 1: Pre-Flash Setup

1. Charge device to 50%+ battery
2. Backup data (flashing wipes the device)
3. Extract the firmware using 7-Zip

Step 2: Configure SP Flash Tool

1. Open SP Flash Tool > Load scatter.txt
2. Select Download Only mode
3. Keep all partitions checked (signed firmware requires full flash)

Step 3: Start Flashing

1. Power off the phone
2. Click Download in SP Flash Tool
3. Connect device via USB (hold Volume Down if not detected)
4. Wait for green tick (7-10 minutes; super.img takes longest)

Key Precautions

• 🔴 Do not modify files (signature will break, causing errors)
• Use Windows 10/11 (64-bit) for driver compatibility
• Disable Windows Driver Signature Enforcement if drivers fail

Post-Flash Verification

1. Boot device to recovery mode > Perform factory reset
2. Check OS version: Settings > About Phone > Build GL-240717V1335
3. Confirm IMEI via *#06# (should match original)

Troubleshooting

• Error 0x8000: Reinstall MTK drivers / Try older SP Flash Tool
• Bootloop: Reflash firmware / Format ALL + Download in SP Flash Tool Note! Lost IMEI
• Dead Device: Enter BROM mode (short test points)

Conclusion

This 24GB factory-signed firmware guarantees a stable, bloatware-free OS for the Infinix Hot 30i X669C. Always match firmware version (GL-240717V1335) to your device model.

⚠️ Note: Flashing official firmware retains warranty but requires technical skill.
