How to Flash Android 4.2.2 ZMUAND1 on Galaxy Beam 2 SM-G3858

For you to experience Galaxy Beam 2 SM-G3858 in a new way, a better Android version is needed. Here is where we tell you how to get one!

Your smartphone should run Android 4.2.2 Jelly Bean. This OS is the version which brings better Bluetooth audio streaming and a USB debug white-list. Other than these goodies, the upgrade also delivers low battery bug fixes and a new Gallery app. Your handset will be able to use other novelties such as a new set of download notifications. The option of long-pressing the WiFi Bluetooth icons in Quick Settings in order to be able to toggle the on/off state is also offered. Your smartphone is going to sport a new set of sounds for wireless charging, too.

After the Android 4.2.2 gets featured on the phone, root access will be revoked from it. System partition is going to be damaged by being deleted. No other feature will be damaged by the update, not even its data or internal / external SD cards.

The ZMUAND1 is the new official firmware your smartphone gets to play with. Released for China this past April, you must only use it on the Samsung SM-G3858. If another model gets installed with it, the firmware will brick that device. Also, use something else than KIES; the firmware’s KIES logo is not activated. OTA is an alternative if the phone you own has stock ROM. In case it doesn’t, our tutorial provides the alternative.Galaxy-Beam-2-SM-G3858

  4. Next, plug the smartphone to your laptop with its own USB cord and wait for the connection to appear. The latter’s going to happen once Odin has a blue sign to pop up.
