How to Update Galaxy S4 I9500 to Android 4.3 UBUEMK2 Firmware
Peru is the second country to receive new firmware for Galaxy S4 I9500. UBUEMK2 is its name and you can use it to get Android 4.3, the latest version, on your device. The full details are below!
As with the previous new firmware, this stock ROM was also released this month. But, like we said, only for Peru (SAM). This tool also comes with the KIES logo not activated, so be sure to update your phone via either OTA with the Software Update button under Settings menu (in which case your device must be running a stock ROM) or this tutorial.
Before you can get the UBUEMK2 on your Galaxy S4 I9500, you should know that there are some cons you’ll have to deal with: if the handset comes rooted, its root access will be revoked and the system partition shall be deleted. The internal and external SD cards will not be affected; the important data will also remain unaffected. Be careful not to use a different smartphone for our guide because it will end up bricked.
The new things you’ll notice on your phone after you update it are the following: lack of serious bugs, an overall better performance thanks to various tweaks and options, longer battery life with the help of numerous other tweaks, new features, new apps and plenty of customization options.
Take the following into account before you start upgrading your device:
- the security programs currently running on the laptop and the Galaxy S4 I9500 must be disabled while the tutorial is going on;
- the battery of your device must be fully charged if that’s needed;
- the laptop you use with this guide must have Windows already running on it;
- you should flash, on the laptop, only those USB drivers that are fully compatible with the handset;
- enable USB Debugging on the smartphone;
- create both a standard backup and a full NANDroid one.
- If you are done with our instructions above, time to performing the very first step of our tutorial. This one asks you to download, on the notebook, Odin from this page and the new Jelly Bean 4.3 official firmware (the version for Peru SAM is available on this site), then use WinRar or WinZip to extract their content on the same notebook.
- As soon as the unzipping ends, you should boot the handset in Download Mode by doing this: simultaneously press and hold Volume Down, Power and Home, wait for the logo of the handset’s manufacturer to be displayed and, when it is, let go of those keys, see if there’s a screen of warning and press Volume Up instead.
- Open, for the next step, the Odin as an Admin on your laptop. Now establish a connection between your Samsung I9500 and the notebook by taking the former’s USB cord and make sure the devices are plugged to one another through its help.
- An “Added!!” message as well as a yellow ID:COM box should then pop up. If they’re not on the display, you can flash, again, the USB drivers or use a much different USB port.
- Once a connection is established, time for these actions: tap BL, select a file with BL in the name, click on AP, opt for a file with AP in the name, tap CP, opt for a file with CP in its name, tap CSC, choose a file which has CSC in the name, tap PIT and choose a file with an extension called .pit.
- Activate, next, these couple of boxes: Auto Reboot, Re-partition and F. Reset Time.
- The Jelly Bean 4.3 UBUEMK2 needs to be flashed on the phone. For that, we will ask you to tap “Start“.
- At the end of the installation phase, your device will reboot; after that it will show a “Pass” message on the display, meaning that the Galaxy S4 I9500 can now be disconnected from the laptop. Since the new firmware is on-board your phone, go look for it by tapping Settings and then About Phone.
If you find the new firmware weaker than the old ROM your handset sported, use the NANDroid backup file to revoke the update process and restore the previous ROM.
