Hotspot Shield

Installing a custom recovery on your Samsung Galaxy Grand 2 SM-G7102 will allow you to do a lot of things that will take your device beyond the manufacturer’s limits.

A custom recovery will allow you to:

  • Install custom roms
  • Create a Nandroid back up
  • Root your phone
  • Wipe cache and dalvik cache.


In this guide, we’re going to show you how to install two types of popular and good custom recoveries on a Galaxy Grand 2 SM-G7102.  These are ClockworkMod (CWM) and TWRP recovery.  We will also show you how to root your device once you have a custom recovery installed.

Prepare your phone:

  1. This guide is only for a Galaxy Grand 2 SM-G7102. Do not use it with other devices.  Check what your device is by going to Settings>More/General>About Device or Settings> About Device
  2. Charge your battery so that it has 60 percent of its life.
  3. Have an original data cable that you can use to connect your phone and a PC
  4. Have a backup of your mobile’s EFS data.
  5. Back up all your important messages, contacts, and call logs.
  6. Turn off or disable Samsung Kies and any Anti-Virus software you have. These can interfere with the functioning of Odin 3 which you need during this process.


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.
