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!

    plz help me out
    I can’t using my phone any more plz bro
    thanks in advance 🙂

  2. Hi, i rooted my phone, everything seems to be allright, but after rebot i get quickly “SuperSu has been stopped”, and the root checker shows that root access is not properly installed. Any idea whats wrong?

  3. Ok. I’ve rooted my phone already and I need to know if I can use gt-i9305 roms because I’m having trouble finding any made specifically for gt-i9305t

  4. 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)

  5. I am not able to install TWRP. the phone jus gets restarted after i get the
    this is the final message i get from odin. and it comes RESET instead of PASS. What should i do?

  6. 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

  7. 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?


  8. Hey i have upgraded the firmware to 4.4.4 Its all working fine. One question, i am not able to change my lock screen wallpaper, i am not getting any option as well to do that though I can change the home screen wall paper

  9. thanks for your time sir, i will try to download the 4.4 then install it using odin. and then root it using saferoot? ill get back to you soon as i made it successfully..

  10. 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.

  11. 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..

  12. hi, i have samsung galaxy s3 lte, but its not i9305, it is SHV-E210L. i really want to root it and update to kitkat..

  13. Any article y would recommend to ensure I don’t end up messing with ghe the phone or ROM

  14. Thank you ever so much. I have been trying this since yesterday and was really frustrating. Can’t imagine it was this simple 🙂

    will now try installing kitkat.. Hope that would be a simple process

  15. I have followed all the steps and got the pass mesage on odin as well but when i start my phone in recovery mode, it starts in odin mode and not in TWRP Mode

  16. Hi i have followed the Root Galaxy S3 GT-i9305 guide and disabled KNOX as well. I used root checker and they said my phone wasnt rooted. May i know what installing TWRP will do? Thanks

  17. 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?

  18. 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 😀
