The Android 6.0 Marshmallow update for the Huawei’s American Honor 5X sets we released some days before as an OTA, and now the said 6.0 update is also available as firmware.
If you haven’t received the OTA yet, firmware is your best choice to secure 6.0 on your device as quickly as possible. You can download the Marshmallow firmware and install it manually on your Honor 5X.
Installing the Huawei firmware is an easy job as you don’t need a special software or an tedious installation of ADB and/or fastboot like stuff. It just involves extracting the Software folder from the firmware and then transferring the dload folder (contains UPDATE.APP file) inside the Software folder to your device, and then using the Update menu in Settings app to install the firmware (it’s UPDATE.APP file).
