  1. What if Odin doesn’t work. My cable is good just that I can no longer mount my phone and see it’s drives on my PC any more


    • I had the problem as you are having now. i just replaced my USB cable with a Samsung one and Odin detected my phone. Otherwise try switching USB ports or use a different version of Odin.

      • I did try a different USB cable, actually a Samsung one. Still dosen’t work. I think Odin would work if my computer can recognize it when I plug the phone in. It did this before so I am baffled. I know I installed SuperSU before all of this and I think it had some weird affect on my phone and when I upgraded that weirdness continued. I am using AirDroid so I can get to my phone now.

  2. i did this step by step but my phone is ( downloading do not turn off target) the word only show so long . why ???

    • I am having the same problem.. it is stuck at the downloading do not turn off target
      after 30 min i had enough i try to switch it off.. .. i tried to unplug it .. i even took the batteries out and replace it back. is shows me dowiloading do not turn off target sign!!

      I even tried to redo the process.. but i am always stuck in this screen! Help!

    • Hi nick, as i have clearly stated, this guide is only for rooting the GT-I9300 version the Galaxy S3. The phone you are having is a Galaxy S4. It Seems you have soft bricked your phone. There is no need to worry as you can easily fix your phone. Now you have to download the official firmware for your Galaxy S3 GT-I9505 and flash it via Odin. This will restore your phone. You can download the official firmwares from here:

      • Thanks lovejeet, I have restore my phone using Kies. I realize that I am using GT-I9305. That’s why it soft bickmy phone. I already found the right file and root it using Odin. But now I can’t seem to use root checker to verify. I am stuck at the screen saying “please wait for root check to complete. System appears to be running very slow” . I’m the background it also say that, “Unfortunately, SuperSU has stopped.” Is there another way to check if my phone is rooted?

  3. odin isnt recognizing my phone i have an s3 i9300 with xxml4 build no. and im am no noob in this cause i have made 2 of my own custom roms for my old phone but wanted to know how to root s3 (only 3 days after buying still learning how to use it) #peaceout

  4. Odin cannot find the CF-Auto-Root-m0-m0xx-gti9300.tar.md5 file! It is nowhere to be found… Not by odin, not by manually searching.

    • You need to download the CF-Auto-Root-m0-m0xx-gti9300.tar.md5 file and then extract it to a folder. After extracting it you will find the CF-Auto-Root-m0-m0xx-gti9300.tar file, which is needed in this guide.

  5. It works the download contains a older Odin file, I’ve used Odin 3 v.3.07 and it works. Great ! Let’s see if we can undelete pictures with DiskDigger for Android

    • Do you use Kies and is your GT-I9300 recognized when you connect it to your computer via USB cable? Then you can skip that step.

  6. Hi lovejeet… I jst want to knw that I hv, galaxy S3 GTI9300 International updated to 4.3 jelly bean. And its base band is DDUGMK1for India (INU), So do I will hv to find root file for the same base band of mine or any cf root file will work to root my phone or with the root file provided by for for rooting s3 GTI9300 4.3 …?? Pls tell me
    Thank u…

  7. Hey lovejeet, just wanted to thank you. I am in Germany and after flashing my GT-I9300 (German baseband) with 4.3 had to learn that none of the framaroot exploits work any longer. Searching for an easy way to reroot my phone I came across your post and was right back on track within 5-10 minutes. Two thumbs up.
    @anyone who says they failed and have a GT-I9300 upgraded to 4.3 with a Samsung stock ROM and followed the instructions to a tee: I don’t believe you. Get your acts together.

  8. Hi, I have a Boost Mobile GS3 and I do everything you said to do. After the cache.img (says it on odin message box) it fails. I have the correct cable and I retried it several times. Any tips?

    • Hi xBlackOw1x, Your Boost mobile GS3 is a different variant variant of the Galaxy S3. This guide is is for the GT-I9300 variant of the galaxy S3, which is why this guide wont work on your phone.

  9. hi. thx for the tut- it worked.. do you know how to get freedom to work on this?i tried to but says server not available or just keep saying processing please wait but nothing happens… thx

  10. Александър Владимиров Иванов

    hey mate i done everything but the root checker says that i don’t have root…can you help me? :)

  11. My screen shows the com as yellow and wont let me click on the f reset time. Should i not do this, I have the galaxy s3 and installed kite and have andriod 4.3

  12. hi..i’d follow your step and odin says pass..but i dont see any supersu installed on my device..and some more the root checker said my device does not have proper root access..i do the process for many times..whats the problem?
    gt i9300
    baseband i9300dxugmk1
    build number xxugmL3

    • I have the same problem. Odin says “Pass!” (after more than a minute btw) but the Root Checker App fails. My guess is that the root checker app needs root access itself. SuperSU has definitely been installed as it asks me whether to allow or deny root access for the root checker app. But it won’t let me allow because you need the Pro version of SuperSU to be able to do this. Thus, I conclude that your device has been rooted.
      But I can be totally wrong, of course.

    Thanks for answer my real problem is the following, I Download OTA The 4,3 android Jelly Bean version for Galaxy S 3 and in technical service of my company they change chipset and the imei of my phone for that reason now i had the official 4,3 version of jelly bean but the mobile network don’t work says its not avalaible please try later, i read a lot of this problem ariza patch and busy box don´t work for me, and thats not my faul because my phone was damaged and repair for the samsung warranty that expired a month ago now i don´t not what to do !!!

  14. Dear lovejeet,
    I have a different problem. After recent update of my s3 GT I 30th to 4.3 jelly beans, many apps stopped working. Internet Explorer, Google search, news play stand, yahoo mail, and many apps have stopped working. Does rooting the phone help solve my problem. Or can you help me in anyway possible.

    • Hi Yamini, the Android 4.3 update has lot of bugs and i suspect the same is affecting your Galaxy S3. You should try to roll back to android 4.1.2 , which is the best stable android firmware for the Galaxy S3.

    • Hi Meffhew, it seems something went wrong with your phone, once your phone is rooted successfully it should automatically restart itself to the home screen. Are you sure you followed all the steps correctly?

  15. Odin doesn’t recognize my SGS3. What can I do? I’ve got the newest Samsung USB drivers. I have bought a new usb cable 2…….please help

  16. Passed Autoroot. My s3 screen has an android on it with Downloading….. DO not turn off target! Doesn’t seem to be doing anything. How long should this take?

  17. Hi Lovejeet,
    The root process worked perfectly thanks. How do i now go ahead and flash a custom firmware?

  18. Hi my phone is S3 I9300. I tried the above steps and it said Pass. But RootChecker said your phone is not rooted. I don’t know what to do next. Thank you.

  19. I followed the instructions but I get stuck at recovery. I have never rooted before so kind of freaking out. What do I do?

  20. Hey Lovejeet, i could do with some help. Odin keeps failing, the messages are:

    Enter CS for MD5..
    Check MD5.. Do not unplug the cable..
    Please wait..
    CF-Auto-Root-m0-m0xx-gti9300.tar.md5 is valid.
    Checking MD5 finished Sucessfully..
    Leave CS..
    Odin v.3 engine (ID:3)..
    File analysis..
    Can’t open the serial(COM) port.
    All threads completed. (succeed 0 / failed 1)

    Any ideas as to what I’m doing wrong?

      • HI, I don’t know about rooting every S3 as I have downloaded 4.3 in December 2014 and when I use root checker it just says that it is not rooted. I have tried loads of stuff from other sites as well including Kingo root which says it does all S3’s and even that does not work.

  21. ive started the root process im getting the blue light with code but when I try and open the pda file there no cf auto in the odin folder please advise and can you tell me wht rooting your actually does the whole problem started when I tried to do a software update on the phone and it rebooted and said processing failed and now it wont recognaise my sim card please can someone help me

  22. hi there, this did not work for me it shows that this device is not rooted on the root chcker, please help me.

  23. Dr Rajiv Kulkarni

    I rooted my s3. i did this basically to change the default fonts. after using file manager app i changed the settings for obtaining necessary permissions. backed up the fonts files in system directory and copied new fonts files and renamed them as roboto font files. i was successful once. when i tried to do it again i got “samsung logo hang”. what is the problem ?

    • Go into the recovery mode….
      Wipe the Dalvic Cache (advance options)
      Wipe cache partition
      Wipe data and then reflash your ROM.

      Note: This will delete all the data on your phone but you should be able to fix it.

  24. Hi Lovejeet,

    Thanks really for the easiest guide that I have came across to root the s3. Was able to root my phone in minutes. I went ahead and also removed some bloatware. I just wanted to check if there is any technique by which I can get the OTA updates on my phone or maybe how to unroot the phone without losing data so that i get access to OTA updates as well.


    • Hi Rohit, Thank you for the compliments. Unfortunately there are no fool proof methods to unroot the galaxy S3 completely. If you want to receive future OTA updates, you will have to re flash the android 4.3 firmware on your galaxy S3, which will unroot your phone.

    • You should also just be able to plug it into Kies and it should tell you if there is an update (at least that’s what happens for me). Checking for updates via your Settings in your phone obviously no longer works…

  25. hey..i am stuck..please help me..i cant select the CF-Auto-Root-m0-m0xx-gti9300.tar.md5 file after i clickt on the PDA button…what can i do?

    • Hi Patrick, its a common problem which occurs after you update the firmware on a android phone. I would advise you to re flash the android 4.3 firmware on your phone. If still your phone doesn’t detect the sim card, then you will have to download and flash the correct modem for your galaxy S3.

  26. When i rooted my device using file then still i do not have root access and after downloadng the root checker from google play it doesn’t display congratulation message for rooting the device.. can some one help me to resolve this issue as i am in a need of rooting my galaxy S3i9300 device.. Thanks..

    • You are flashing the wrong CF-Root file. You will need to extract the CF-Auto-Root-m0-m0xx-gti9300.tar.md5 file from the CF-Root zip file and flash it using Odin.

  27. Hi, i’m trying to root my s3 but when i put my phone in download mode i have a screen in which there is the android robot and in the up left corner there are:
    odin mode
    product name: gt-i933
    custom binary download: no
    current binary: samsung official
    system status: official
    and in the middle there is:

    do not turn off target!!

    what i have to do?

    • Once your phone is in download mode you have to connect it with your PC and use odin to flash the CF root file provided above. But before that make sure you ave the I9300 version of galaxy S3.

  28. Please Help – Samsung G3 19300 Android V4.3 – just updated (why did i?)

    HI great details involved in your instructions. JUst regarding the download mode. When my mobile goes into this mode it looks different compared to all pics I have seen so I am confused what to choose. I have chosen the ‘apply update from ABD’ but the mobile does not show as connected to odin. When the mobile is on properly it does show it is connected on odin and pc. Shall i be choosing another option on this screen – Pic provided.

    I do have 2 versions of keys installed and all the samsungs whow and work fine on those. Due to this I am pretty sure the updated usb drivers are connected.

    I have tried safe root, one click root and others which do not work at all. I have supersu already installed on mobile if this even matters i would not know.

    Funny thing is i only want to root so i can add something to a game im hooked on, lol.

    Any assistance you can offer??

    Thank you in advance

  53. hi. i dont know whats the problem.

    when i tried rooting my samsung s3, it did say PASS. however when i checked via Root checker, it says rooting was not properly done.

    is it the root checker app that’s having a problem or my device itself? coz again it did say PASS in Odin.

  54. I have Samsung S3 I9300 model. I did factory reset and after that some text is coming in yellow color with black background. Someone told me that it is in factory mode.

  56. Hi! My computer wasn’t able to recognize my phone and tried many of the suggestions provided in this and other forums. In my case, the solution was to use the program usbdeview and “clean” my usb ports. After that everything run smoothly. I’m posting this in the case you want to compile a list of potential solutions.

    Hope it helps!

  57. Hi Lovejeet thanks for the tutorial and just want to say its good of you to take so much time to do this and especially to answer all the same questions being asked over and over (instead of them just checking through all the replies first) well done man, it’s appreciated :-).
