Update Galaxy Tab 7.7 P6800 to Official Jelly Bean 4.1.2 DXMD3 Firmware

The Samsung Galaxy Tab 7.7 P6800 can now be manually updated to latest Jelly Bean 4.1.2 OS as the DXMD3 firmware has been made available for us. So, by using this step by step guide you will be able to learn how to flash an official update on your Galaxy Tab 7.7, all being explained during some easy to follow and to apply steps. Therefore, if you need to install the stock Android 4.1.2 DXMD3 software on your Tab 7.7 and the OTA version isn’t available for you then complete this tutorial.

A manual update procedure when dealing with official firmwares is being required if the OTA has been rolled out in selected markets only, if the OTA isn’t received by your device, or if you have a rooted or installed with a custom ROM handset. Of course, you can anytime manually flash the stock software if you need to restore the warranty, un-root the system or for downgrading to stock Jelly Bean OS. Now, in our case, we will be checking on how to update the Galaxy Tab 7.7 P6800 with the Android 4.1.2 DXMD3 system.

But before beginning with the update operation you need to learn something about the new OS and also you need to prepare your tablet for the flashing process that will shortly follow. So, you need to know that the Jelly Bean DXMD3 OS is the latest Android 4.1.2 update released by Samsung for the Galaxy Tab 7.7; therefore the platform is stable and will smoothly run on your device. Furthermore, the firmware is coming with no bugs or issues along with important features, apps and capabilities that will improve the performances and the Android experience that is running your Tab.

This method is suitable with both rooted and locked tablets, so you don’t have to worry about these aspects. Actually, for those who have rooted their Galaxy Tab 7.7, here is what must be mentioned: after applying the stock Jelly Bean OS, the root access will be revoked, the bootloader relocked and the factory restrictions reinstalled. Therefore, you will then have to re-root your handset by following a new procedure that is suitable with the new DXMD3 ROM.

But the mentioned aspects come along with an important advantage: in case your device is powered by a custom ROM, now you will be able to flash the stock and default version of Android which means that you can safely restore the warranty of your handset (the warranty gets void when you unlock the bootloader or root the system).

Now, in order to succeed with this method you need to have access to a Windows powered computer, to your tablet and to its USB cable. For avoiding the unpleasant situations, then ensure that: on your computer and Galaxy Tab 7.7 there are no security programs installed (if different deactivate or uninstall the same); your handset has more than 60% power left (if not charge the battery or else the device might get turned off while you are trying to update its system); enable the USB debugging option on your Tab by going to “Settings -> Applications -> Development -> USB debugging”.

Also, it is more than recommended to backup the Galaxy Tab 7.7 data before starting to apply the Jelly Bean 4.1.2 DXMD3 OS. In this way you can be sure that nothing bad happens with your personal saves and info. Do a full backup for saving the contacts, messages, call logs, internet settings, EFS, market apps and even consider in making a Nandroid backup – if your device is currently rooted and installed with a custom recovery image.

Be aware as this tutorial is compatible only with the Samsung Galaxy Tab 7.7 model number P6800; don’t use the steps from below if you own a similar or different Android based device as you can end up in bricking your handset.
