How to Install Android 4.3 KEUFNC1 on Galaxy S4 SCH-I959

Galaxy S4 SCH-I959 is going to receive valuable novelties via an update we prepared for you. You must apply it only on this smartphone, otherwise you’ll just damage whatever device you may have. Let’s see what this update looks like!

The Samsung SCH-I959 is going to need Android 4.3 Jelly Bean KEUFNC1. This firmware is fully compatible with your phone and it came out last month for China. Anycall is the carrier you should be using if you want the upgrade.

If you’re armed with the right smartphone version, you can enjoy lots of surprises after our procedure. All of them will get together and improve many aspects of your handset. We’re talking about new features, no bugs as well as customization options. If you want new apps, you can have them as well. Your device’s battery won’t be as weak as it is now: the update also means tweaks that help it operate significantly better.

If you’re set on updating the phone with Samsung’s popular KIES, the firmware doesn’t let you do that. If your smartphone has stock ROM, you can use OTA for this procedure. Should your handset not be equipped with this stock ROM, you can follow our tutorial below.

Before getting to the upgrade guide, you should know what damage to expect from the update if the phone’s rooted. Installing the new firmware on such a device means several disadvantages. One of them is this: your phone’s system partition will be erased. Another disadvantage has to do with root access. Once the upgrade’s been completed, this root access will be revoked. But your device’s important data won’t get the same treatment; and neither will its internal and external SD cards.Galaxy-S4-SCH-I959

  • your notebook must have USB drivers for this particular phone on it;
  • the laptop you use for this procedure should run Windows;
  • the smartphone’s security programs need to be disabled;
