For those who have read the article 'Guide to updating Android 5.1 for Honor 4C' and wish to revert to Android 4.4 on the Honor 4C. Today, I will guide you on how to flash the ROM back to 4.4 for this device.
Note: When performing, you should prepare a good cable, charge the battery to over 90% to ensure the device does not lose power, and do not unplug the cable while installing the ROM. You must have some knowledge about upgrading the device and back up important data before proceeding.
Furthermore, there may still be risks involved in the upgrade process, so please think carefully before upgrading, and this article will not be responsible for this issue.
To initiate the downgrade, we need to follow these steps:
Download the 4.4 downgrade version of the device from here.
After downloading, let's begin the process:
Upon extracting the 4.4 file, we will obtain 2 folders dload and dload2.
Copy the 2 folders to the memory card (do not place them inside any folder). For example: E:dload and E:dload2.
Note: If you already have the dload file, delete it before copying. It's best to format the memory card for safety.
Insert the memory card into the phone. Then, navigate to Settings > System updates.

Select local update. Choose the full package: UPDATE.APP and install. After that, the device will automatically restart to begin the downgrade process for you. It takes about 5 minutes.

After completion, the device will notify you, restart, and upgrade Android apps for about 5 minutes.
Upon booting up, open the file manager app, delete the dload folder, and rename the dload2 folder to dload. Proceed to the update manager to redo the downgrade process to version 4.4.
For the best downgrade experience, it's recommended to restore the device to factory settings both before and after the downgrade. Wish you all success.
