How to Update Galaxy Mega 6.3 GT-I9205 to Android 4.2.2 ZHUCML4

If you live in Hong Kong and want to upgrade your Galaxy Mega 6.3 GT-I9205 to Android 4.2.2, we found the perfect tool. More precisely, new firmware going by the name of ZHUCML4. And we wish to share with you the method of updating your phone with its help.

For all of you interested in the update, we have just the steps to help you. Before we reveal them, we must ask you to never upgrade a different model with our tutorial. If another smartphone is used today, you will eventually brick it. Also, if your Galaxy Mega 6.3 I9205 has already been rooted, expect the following: the system partition shall be deleted and root access will be revoked. These are the two major cons you’ll encounter. The important data won’t disappear from your handset, though. The internal and external SD cards are also going to be preserved.

To perform the upgrade, you can also use Samsung’s KIES because your phone sports an activated KIES logo. We must warn you of the following: only a Galaxy Mega 6.3 GT-I9205 with a stock ROM must be used for this method. You won’t have to sport such a model if you’re using our guide.

The novelties of the ZHUCML4 are made of a new set of download notifications, a USB debug white-list and a new Gallery app with superior speed when loading. But wait, there’s more: the possibility to long-press the WiFi and Bluetooth icons in Quick Settings so that you can easily toggle the on/off state, low battery bug fixes and a new set of sounds for wireless charging. If you’re worried about bugs with the Bluetooth audio streaming: they don’t exist on this version.Galaxy-Mega-6.3-LTE-I9205
