How to Install Android 4.3 ZMUAND1 on Galaxy Mega 5.8 Plus GT-I9158P

Galaxy Mega 5.8 Plus GT-I9158P is featured here as the phone to have Android 4.3 by the end of this post. If you can’t wait to experience this OS, we have just the tutorial for you!

The Galaxy Mega 5.8 Plus I9158P and the new OS are the stars of today’s guide. This operating system can be yours to discover after ZMUAND1 is installed on your phone. Launched last month for China, this firmware doesn’t let you flash it via Samsung’s KIES. If you do want an alternative to our tutorial, you can use OTA (over-the-air). Generally, this method must only be used on a smartphone with stock ROM.

When you go with an upgrade on a rooted device, you have to suffer certain consequences. Like, for instance, ending up with a deleted system partition. Then there’s also this disadvantage: the phone’s root access will be revoked. The data which is the most important for you will be saved. Nothing will affect the handset’s internal and external SD cards.

When your Galaxy Mega 5.8 Plus GT-I9158P is equipped with the Jelly Bean 4.3, you will deal with fresh new additions. They will allow you to use your smartphone over longer periods of time, play with new apps and so on. Fortunately, your handset will not have to suffer damage from major security problems.Galaxy-Mega-5.8-Plus-GT-I9158P
