Guide: Install Android 4.3 ZCUANA1 on Galaxy Trend 3 SM-G3502C

Your Galaxy Trend 3 SM-G3502C can be deprived of a stellar performance. If you want to experience that, we advise you to upgrade your device with ZCUANA1 official firmware.

The new firmware came out in January this year for China with a deactivated KIES logo. If you wish to get Android 4.3 on your smartphone, we and the new firmware will help. Just be sure to use only the Galaxy Trend 3 SM-G3502C for this tutorial. A phone which is another model won’t end up updated; it will end up bricked instead.

If the handset is the rooted version, the update will leave it without root access. The system partition will be deleted, but the phone’s important data shall remain intact. Your device’s internal and external SD cards won’t be damaged.

When the new firmware doesn’t have an activated KIES logo, you won’t be able to use KIES software for the update. This means that the upgrade can only be performed via either this guide or OTA. Should you consider the use of the OTA (over-the-air) method, your handset needs a stock ROM to be running on it.

The goodies which the Android 4.3 is all about will naturally become part of the phone after the update. Here is what you’ll receive: a wide array of new apps, tweaks to help the device perform better and last longer and new features. You will also be able to fully customize your smartphone. The update will make sure that there are no security issues to deal with.Galaxy-Trend-3-SM-G3502C
