Install Android 4.3 Jelly Bean Leaked Firmware on Galaxy S4 LTE GT-I9505

The users of Samsung Galaxy S4 have been patiently waiting for the latest version of Android to come their way for a long time. The rumors of Android 4.3 Jelly Bean update for the device, by the end of October, have finally started realizing and the leaked Android 4.3  test firmware for the Galaxy S4 can be taken as a solid confirmation. If you have any variant of the device, you’ll have to wait a little more to get the new taste of Jelly Bean. However, if you own the LTE version of the Galaxy S4 with model number GT-I9505, the treat has arrived for you in its raw form.
Usually, Samsung takes a little longer time in sending the latest Android updates to its flagships, but this time it has taken just about 2 and half months. The available Android 4.3 firmware I9505XXUEMI8 is the leaked version of the official one and therefore it might or not be as stable in performance as an official release should be. We tested this firmware on our S4 and having used it for more than 40 hours, we can say that except for some Wi-Fi connectivity issues now and then, it is good as a whole. Keep in mind that it is a “test” and “taste” firmware both, so do not expect perfection!


The Android 4.3 based  I9505XXUEMI8  firmware is meant only for Samsung Galaxy S4 LTE GT-I9505. Do not dare try it even in dreams, if you have some other variant of the Galaxy S4. Install the firmware to your device at your own risk. We’ll not be responsible for any damage done to your phone.
