Your itel City 100 C671L firmware package usually comes zipped. If you haven’t downloaded it yet, grab it and then extract it using WinRAR or 7-Zip. Once you’ve extracted the file, open the folder and make sure it contains the .pac file before you continue with the flashing process.
Remember, updating the stock firmware on your itel device will wipe all your data. This is actually a good thing because it helps fix various software issues. These can include FRP lock problems, app glitches, slow performance, forgotten pattern locks, issues where the phone is stuck on the itel logo, Wi-Fi and Bluetooth connectivity problems, battery draining too fast, or even soft brick situations.

Choosing the Right Firmware Version
Before you start flashing, follow these steps to make sure you pick the correct firmware:
- Identify Your Device Model: Go to “About Phone” and confirm that your model is indeed the itel City 100 C671L.
- Verify the Build Number: Look for identifiers like “C671L” within your device’s build details.
- Confirm the Chipset: Based on itel’s specifications, the City 100 C671L uses a Unisoc T7250 (12 nm) CPU. It’s an Octa-core processor with 2×1.8 GHz Cortex-A75 cores and 6×1.6 GHz Cortex-A55 cores, paired with a Mali-G57 MP GPU.
- Match the Firmware Version: Carefully check the firmware version and regional details to ensure it’s compatible with your device’s specifications. This helps avoid potential issues.
- Verify In Recovery Mode: If you’re not entirely sure about your City 100 C671L’s chipset or firmware version, you can restart your device into recovery mode for more details. To get into recovery mode on itel phones, turn it off completely, wait about 8 seconds, then press and hold both the Power and Volume Up buttons. Release the Power button once you see the Itel logo, but keep holding the Volume Up button. You should then see the Android robot with “No command.” Release the Volume Up button, then press and hold the Power button again and quickly tap the Volume Up button. This method should show you the firmware details, helping you choose the right version and avoid any risks.
