When it comes to prompt firmware updates, the boss of Android (Google) always wins the race. And that is why if you happen to one who does not like waiting for months, or sometimes eternally, for system updates, going for a Nexus device might be the best decision. The major difference between Google and other OEMs of Android is this— while the former seldom forgets to send latest updates its older devices, other manufacturers and carriers often ditch their old devices and and in most cases, postpone the updates for newer devices for months.
At a time when we are all going frenzy about the newly released Android 4.4 KitKat, Samsung devices like Galaxy S3, Note 2 and others are still waiting for the due software updates for a long time. When dumping smartphone market with its devices becomes the sole focus of a manufacturer, things like timely updates, good performance and after-sale service are thrown to corners.
Anyway, the users of Samsung best-seller smartphone, the Galaxy S3, are stuck with Android 4.1.2 for ages now and what they have been rewarded so far is just a couple of leaked firmwares. 4 long months have been passed since the last Android 4.2.2 leaked firmware for the phone, and when we were all hopeful of receiving this update, Samsung shattered our joys by cancelling it. The company promised to upgrade the device directly to Android 4.3. What we have now is another leaked Android 4.3 firmware with build number, I9300XXUGMJ9.
The firmware given below is a branded one but it can be installed on any Samsung Galaxy S3 with model number GT-I9300. Since it is a leaked firmware, do not expect perfect performance. We tested it and having used it extensively for hours, we can affirm that it is pretty stable and can be used as a daily driver.
There is no doubt that this update is a big leap from what you have on your Galaxy S3 GT-I9300 and having installed the Android 4.3 on your phone, you’ll notice a lot of changes and new features:
Please note tat the available firmware has wipe attribute and this simply means that it will delete all your data and apps present on the internal SD card. It’s therefore recommended that you backup your device before going for installing it. Also, some users complain that they lost their their phone’s EFS/IMEI after installing the firmware. If you have root access on your Galaxy S3, please backup its EFS data using this tutorial. Finally follow the instruction at your own risk. Nobody like to be held responsible for a mishap!
(We’ll try to add a torrent link soon.)
At the completion of the procedure, your Galaxy S3 will reboot automatically and when it boots up, you’ll have Android 4.3 Jelly Bean firmware installed on it. Enjoy!
