Update Galaxy Tab 7.7 GT-P6800 to Jelly Bean 4.1.1 using Nexness PRO ROM

Yes, there is a way to bring the Android 4.1.1 Jelly Bean OS on your Samsung Galaxy Tab 7.7 Wi-Fi+3G GT-P6800. How exactly, you ask? Simple: via a custom ROM, as usual.

This custom ROM is made possible with the help of DakiX, a member on the XDA Developers forum. He created it and gave it the name of Nexness PRO custom ROM. The ROM was born from a combo of AOSP sources and CyanogenMod 10. This custom ROM has been zipaligned, deodexed and also rooted. And is based on Jelly Bean build JRO03H.

Requirements

If you cannot wait to get the Jelly Bean 4.1.1  update, then you should go and install the Nexness PRO ROM. But not before following some simple rules: don’t think of installing this ROM on devices that are not Samsung’s Galaxy 7.7 Wi-Fi+3G GT-P6800. If you do install it on other models from other companies, then your phone will be in trouble. Then you should check and see whether or not your tablet has ClockworkMod Recovery pre-installed on it. If the answer is yes, then download these files to the laptop/PC you use: Google Apps package (a file called gapps-jb-20120726-signed.zip) and Nexness Pro custom ROM for Galaxy Tab 7.7 GT-P6800. If you don’t see the ClockworkMod Recovery anywhere, grab it.

There are tutorials on the Internet on how to do that. Next, do a backup of those things that are on your device that you consider of the utmost importance. Final requirement is to see if the battery is fully charged (or at least over 70%). If it is not, then charge it asap.Samsung-Galaxy-Tab-7.7-GT-P6800

Important instructions

If you made sure that your tablet meets all the above requirements, you are free to install the Nexness PRO custom ROM on your tablet. And the steps to follow are below.

You can stop it once the tablet enter into ClockworkMod Recovery booting mode (at this stage of the installation process, if you want to do a selection, press the key for Power; should you wish to scroll either down or up: press the buttons for Volume).
  4. For step 4 you need to choose Factory reset/Wipe data. This needs to be confirmed on the the next level.
  5. Step 5: Opt for Advanced and then for Wipe Dalvik cache; do a confirmation of this on the screen that will appear next.
  6. Step 6 consists of selecting the installation of the ZIP file from the internal SD card. After that you must choose the ZIP file from the SD card. And then choose the ROM’s ZIP file; this also needs a confirmation that you intend to have it installed.
  7. For step 7 you have to install the GApps pack like you did for the sixth step.
  8. The eighth step says that you need to go back to the tablet’s recovery menu.
  9. For the final step of the update you have to restart the entire operating system. Doing this is going to make the device turn on.
