Root And Install TWRP Custom ROMs

There have been a fair amount of custom ROMs and MODs developed that can bring new life to the relatively old Samsung Galaxy Mega.  This is a good thing as it doesn’t look like Samsung is going to be releasing new updates for this device.

If you have a Galaxy Mega and you want to update it by flashing a custom ROM or MOD, you need to have a version of custom recovery running on it.  In this post, we are going to show you how you can get the latest version of TWRP custom recovery, the TWRP, on a Galaxy Mega 6.3 and 5.8.

With TWRP on your device, you can flash custom Android 5.0 ROMs on the Galaxy Mega 6.3/5.8, effectively updating it.

NOTE: To install this latest version of TWRP on your Galaxy Mega 6.3/5.8, you need to already be running Android KitKat.  Before going on with the installation, make sure you are updated.

Prepare your phone:

  1. Only use this guide with these Galaxy Mega variants:
    • Galaxy Mega 6.3 I9200, I9205 LTE
    • Galaxy Mega 5.8 I9150, I9152

Do not use this guide with any other device or you could brick the device.  Check that you have the correct device by going to Settings> General/More and About Device.


  1. Charge battery to at least over 50 percent to make sure you don’t run out of power before installation ends.
  2. Enable USB debugging mode by first going to Settings>Developer Options>USB debugging. If you don’t see Developer Options, go to About Device and look for the Build Number. Tap the build number seven times and then go back to Settings.  Developer options should now be there.
  3. Back up all important SMS messages, call logs and contacts as well as important media content.
  4. Have an original data cable to connect your phone and a PC.
  5. Disable Samsung Kies, Windows Firewall and any Anti-virus programs first. You can turn them back on when installation is finished.

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device.  Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.  Be responsible and keep these in mind before you decide to proceed on your own responsibility.  In case a mishap occurs, we or the device manufacturers should never be held responsible.
