How to Root and Install TWRP on Galaxy S3 GT-I9305 LTE

DJ | 24 Mar 2014 | Root/ Samsung

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. By using our guide, you can root and install TWRP on Galaxy S3 GT-I9305 LTE very easily.. Lets get it started!

Warning!

  • Rooting voids warranty, DroidViews or any of its community members do not encourage rooting and are not responsible for any damage to your device. Perform everything at your own risk.

      Happened the same for me, then it worked. I did everything, and i only got RESET as last message in the message-window. I did let the phone stay connected as it booted into android, and still no PASS in Odin.. Then maybe 10 minutes later, (phone still connected), I checked Odin again (which I never closed), and it the said PASS. (I do not recall if I rebooted the phone after the first boot, but I probablt didn’t)

    Hi – I see where step 4 says ‘Make a Nandroid backup of your current ROM’ and I’m wondering how to make a nandroid backup on an unrooted phone given that this is a guide (which I intend to use) for rooting the Samsung Galaxy S3 Lte

    Thanks in advance

      Hi, that’s not a necessary step and I am surprised myself why our writer mentioned that here. However, when you click the link it shows a post on Nandroid Manager which can create a rom backup without booting into recovery: https://www.droidviews.com/manage-and-restore-your-nandroid-backup-without-booting-into-recovery-with-nandroid-manager/

      Anyway, I am going to remove that step. You can continue without worrying about it. Thanks 🙂

    Hi,

    I have updated the Galaxy S3 LTE i9305 to KitKat 4.4.4. using I9305XXUFNI3_I9305DBTFNI3_DBT. The problem is that the the phone then restarts it starts in factory mode. I have tried to root it following your instructions, but again after the phone restarts it continues in factory mode (it has the text with config parameters written accross the screen) and the root checker tells me the device is not properly rooted.

    A lot of these guides on kitkat 4.4.4. on the SE i9305 seem more based on theory than on an actual real case of someone carrying out the upgrade. Can you confirm how i get out of factory mode and/or how i definately root this phone and firmware?

    Thanks,
    carbar

      Yours is a Korean model. If you want to root your device on 4.3, try Saferoot: https://www.droidviews.com/root-verizon-galaxy-s3-android-4-3-vrucml1-firmware/

      To update your Galaxy S3 to Android 4.4.4, download this firmware: http://samsung-updates.com/details/33899/Galaxy_S_3_LTE_Korea_LGplus/SHV-E210L/LGT/E210LKLUKNI3.html

      Then install it using Odin: https://www.droidviews.com/install-stock-firmware-on-samsung-galaxy-devices-using-odin/

        thank you for the quick reply sir, thankyou for the info.. is that 4.4.4 version also korean? because I dont want it to be that version “korean”.. I want it to be english or should I say “localized” so that there will be no korean apps on my phone..

          Yes, you will have to install the Korean ROM on the Korean model. The firmware has English language too. By rooting the device after installing the firmware, you should be able to remove those Korean bloats.

          Volume down is for Odin mode. Try Volume Up + Home + Power. Keep them pressed for longer than you do to enter Odin mode.

    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 😀

      Have you installed TWRP too? If yes, download this: http://download.chainfire.eu/supersu

      and install using TWRP recovery.
