How to Manually Upgrade Huawei Honor 3C to Android 4.4.2 KitKat (v4.7.1) Firmware

Here’s a brief tutorial on manually upgrading your Honor 3C (H30-U10) to the latest Android 4.4.2 KitKat OS update. Once you’ve downloaded the necessary Android 4.4.2 (version 4.7.1) firmware package, you can easily apply it manually using your phone’s stock recovery. Just follow the step-by-step instructions given below.

Manual Android 4.4.2 Upgrade Method

1. Prerequisites

• Android 4.4.2 (v4.7.1) upgrade package (Download here)
• 1GB microSD card with FAT32 formatting
• A USB cable with latest USB drivers
• And at least 25% of battery

This update method applies to the H30-U10 variant(s) of Huawei Honor 3C/Glory 3C only. In case there was any misunderstanding, the same tutorial works on H30-T00/H30-T10 variants too, but you’ll have to download the respective update packages from EMUI.

Note: This update will entirely wipe out your phone’s memory while installing. Therefore, you are strongly recommended to backup all your apps, settings, contacts, messages, and other important data before proceeding. This can be done using your phone’s inbuilt Huawei backup utility on a separate microSD card. You can encrypt your data if you want but will require password every time you try to access its contents.

 2. Installation Procedure

1. Connect your phone to a PC using USB cable
2. Format your SD card in FAT32 and create a new folder “dload” in its root directory
3. Extract the ZIP file and copy its contents (“UPDATE.APP”) to the “dload” folder
4. Disconnect your phone from PC
5. Reboot into recovery mode by powering off your phone and then holding Volume Down + Volume Up + Power Buttons simultaneously
6. Within a few seconds, the update process will be automatically initiated. It will take about 3-4 minutes.
7. When it gets completed, you can use the Backup utility to restore all the data you backed up earlier.

Alternate Method (Easier)

1. Copy the update contents to your SD card as mentioned earlier
2. Navigate to Settings > Updates > System Updates
3. Tap ‘Local Update’, carefully read all the warnings and then perform a quick backup of your device (in case you haven’t done that already)
4. Next, tap ‘Confirm’ to proceed with the update installation. It shouldn’t take more than 5 minutes.

And whoosh… you’re done! That was damn easy, wasn’t it?

Disclaimer: Do bear this in mind that despite the fact that this method has been fully tested, I shall not be held responsible if your device gets screwed up at any point. Apply this update at you own risk.

Enjoy the chocolaty update!
