We’ve already covered up rooting guide for GSM Galaxy S3 and all other variants, yet the one that is still in lane, is the Samsung Galaxy S3 I9305 LTE. The question that might just strike is “Why would I need root?”, and shall I say “Why not!”. Everything you need, to explore your device’s boundaries begins here through this guide.

Say, you need to remove pre-loaded bloatware from your device, you need to alter the system’s CPU freq and other measures, you need to move apps from your Internal to external storage to save space, you will eventually need to root. It not only lets to perform such functions but also makes you the actual owner of the device having complete control over it and makes it eligible to flash Custom ROMs and Kernels. Another important prospect is a Custom Recovery, which aids you in flashing any custom zip files.

The Nexus line of devices follow some easy procedure by directly flashing the SuperSU binaries, HTC devices needs their own tools and so does others. Samsung, since the beginning of the Android career used the very famous Odin tool and hence it does play the most important role here.

  • I have followed this rooting guide and everything seemed to be going well and all i seem to keep getting is a security message pop up on my phone saying an application attempted to access system on your device without authorisation. this attempt has been blocked. Deleting applications obtained from unauthorised sources may improve security. Super user does not work and twrp will not install on my phone. It there anyway way of reversing what i have done or putting it right?

  • Hey there, I followed your rooting guide to the letter but Im still running into some problems. I’ve managed to do everything correctly however into the final phases of the process the system is unable to execute SuperSU and it also says that the device does not have proper root access after using the root checker. A lil’ help is appreciated thanks 😀
