How to: Install Official Firmware For Android 4.4.2 XXUFNB9 Kit-Kat in Galaxy S4 I9505

Last updated: October 2, 2018.

The Galaxy S4 I9505

The Samsung Galaxy S4 i9505 has finally received the official firmware for the Android 4.4.2 KitKat with build number XXUFNB9, which is highly praised for its stability and notable cleanliness. This most recent update from Samsung can be acquired through an update in Samsung Kies or OTA, but for those who have not received that notification, you have the option to install the newest firmware manually.

If you are one of those people who will be going through the manual method, this article will provide you with a step by step guide so that you can successfully have a copy of Android 4.4.2 KitKat. It is necessary for you to carefully read and properly follow the provided instruction so that you will not encounter issues with the installation. Rooting your device or having a custom recovery is not a requirement because you will be installing an official firmware. Those who are familiar with Odin will have a relatively easier time in completing the process.

Before proceeding with the installation, take note of the following important things to consider and/or accomplish:

  • This step by step guide can only be used for Samsung Galaxy S4 i9505. If this is not your device model, do not proceed.
  • It is imperative for you to keep a back up of your contacts, messages,and call logs. This will prevent you from losing important information in case a problem occurs in the process.
  • Also remember to back up the mobile EFS data of your phone first. This will ensure that your device will not lose connectivity.
  • Your remaining battery percentage before starting the installing should be at least 85 percent.
  • Allow USB debugging mode on your phone
  • The methods needed to flash custom recoveries, ROMs, and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.
  • Do not attempt to Factory Reset using Stock Recovery because it will delete everything on your device (including your photos, videos, and music files).
  • If you are using custom ROM and you upgrade your device to this ROM, you will lose all of your app data.
