How to Update
Compatibility Note: Verify your phone’s model number from Settings > About phone before downloading the firmware. Also make sure that your phone is already running a C432 based European firmware.
Step 1. Download the appropriate firmware for your variant and extract the contents of the zip package. You’ll get a large file named UPDATE.APP.
Step 2. Connect your phone to your PC and create a new folder “dload” in its external microSD card.
Step 3. Transfer the extracted UPDATE.APP package to the new folder you created in the previous step.
Step 4. Unplug the USB cable and turn your phone off.
Step 5. Now hold Volume up + Volume down + Power keys for a few seconds until the device starts up.
