Supported Phones
This recovery should theoretically work on all LTE variants of SGS3.  Do not flash on other phones!

**Important Note about exFAT
Team Epic's CWM cannot support exFAT.  Read this page why, and how you can easily avoid this problem with a one-time conversion of your sdcard.

    How to Install CWM with Odin (Windows only)
    Currently the only way to flash the SGS3 is the Odin utility on Windows.  Heimdall (for MacOS X and Linux) does not yet work on SGS3.
      Step by Step Instructions
      1. Install USB driver on Windows.
      2. Put SGS3 into Download mode.
        • Power off.
        • Power on, immediately hold down Volume Down, Home and Power buttons until a Warning message appears.  Press the Volume Up button to proceed.
      3. Unpack the Odin .zip and run Odin on Windows.
      4. Plug USB cable into phone and computer.  If your drivers are setup properly, Odin should recognize the phone by turning the COM box on the left blue with a message "Added!!"
      5. Uncheck the Auto Reboot option.
      6. Click on PDA, select the CWM-Recovery-LTE-SGS3-v*.tar.md5 file.
      7. Click Start to begin flashing.  If it succeeded the box on the left should turn green and say "PASS!"
      8. Unplug USB cable.  Remove the battery to ensure power off.
      9. WARNING: Do not boot into Samsung's ROM without first applying our Root .zip.  Samsung's OTA updates install /system/etc/install-recovery.sh and /system/recovery-from-boot.p, which cause Samsung's ROM to replace the recovery image you had just flashed with the stock recovery.  Our Root .zip removes these files, thus preserving your custom recovery.  Follow the directions below to boot directly into CWM recovery.
      How to Boot into Recovery on SGS3
      1. Unplug USB cable.
      2. Power off.  (Removing the battery is the best way to ensure complete power off.)
      3. Power on, immediately hold Volume Up, Home and Power buttons.  Let go when you see tiny blue text near the top of the screen.
      4. In recovery you can flash new ROM's or customization to your current ROM.  If your SGS3 is new, you may want to flash Team Epic's Root from Recovery tool, the easiest way to root the stock Samsung ROM.
      Troubleshooting Odin
      The #1 cause of Odin flash failures is a bad USB cable.  USB cables that come with phones are often not good enough.  It is hit or miss with retail USB cables, you might try two seemingly identical cables but only one consistently works.  Find a USB cable that works for Odin and stick with it. Installation Instructions
      1. Copy the CWM-Recovery-LTE-SGS3-Sprint-v*.zip to your phone's internal storage.
      2. Power off.  (Removing the battery is the best way to ensure complete power off.)
      3. Power on, immediately hold Volume Up, Home and Power buttons.  Let go when you see tiny blue text near the top of the screen.
      4. Flash CWM-Recovery-LTE-SGS3-Sprint-v*.zip.

      11. There are several versions of CWM for the Acer Iconia Tab A500 on XDA and TegraOwners.com that allow toggling the backup and restore of /data/media on or off. That way you can choose to backup, wipe, or restore the internal "sdcard" on your own. You don't necessarily have to backup everything. You should take a look at them.

      19. So, as long as I flash this using Odin, and then flash the root zip(even though I'm already rooted), then this will give my Tmobile gs3 a fully working cwm that will read and write to my sd card? I'm sorry for asking, but I like to ne very sure that things are compatible before I just jump in!

      20. Using Rogers 16GB SGH-I747 and it won't boot. Tried twice now using v4.

        Was however able to flash the Root zip as per instructions, from my external SD card no less. So something worked. But I wish I could use my phone. What am I doing wrong?

        Found this via XDA thread.

      28. I have ODIN 3.07; does this matter when rooting as you have a link for v 3.04? I was able to load the tar file using v3.07; however, I am not able to get the TeamEpic-Root-from-Recovery-v5.zip file moved to my phone. I had to create a file first and then move the file, but when I try to go into recovery, it shows stock recovery....

Tried to power off and go back in but got the blue light and blank screen. Finally untared the tar.tar file to just a .tar file and was able to download it with ODIN, and get into CWM. Then was able to flash the rooted rom and that worked too. but still the blue light and blank screen. Finally tried the unroot procedure, and again everything wokred as expected exceptthe reboot.

        ReplyDelete
      53. Oh man I hope you can help me! The tutorial was great and everything seemed to go well... untill... It all worked and I was using my phone as normal. I check that I had root access; I did. I went in to the regular phone settings and a popup message appeared saying the "System wants SuperUser access. If you did not initial this click deny, etc.."

        I was unsure what to do since I hadn't yet done anything. And I also thought if the System needed Root access it would have already had that. I clicked deny; probably the wrong choice. The phone imediately rebooted and got to the Samsung splash screen on boot up and just hung there. No matter what I did from that point on that's all the phone wanted to do.

        I could get the phone to boot into Download mode. I tried re-installing the CWM Recovery Zip with Odin and booting into Recovery mode (volume up botton book). I got the option to install off the internal memory. That seemed to work, then reboot. This time the splash screen lead to and "Android is updating... starting apps..." screen (or something like that) for a very long time. Then it booted again, and it hung on the Samsung splash screen again.

        If it matters I was going off the video. I only now noticed in the written instructions it mentions installing a root.zip file in step 9. The video didn't mention this so I missed it. Could that be part of the problem?

        I found your Restore instructions:
        http://www.epiccm.org/2012/06/sprint-sgs3-stock-restore.html

        But they require files to be installed on the internal memory, which I can't access without the phone booting (unless there's a way to push them with Odin). Can I install off the external SD card? Do I have any hope to fix this?

        Any help you can offer is MUCH appreciated!

        ReplyDelete
      54. Great write up and MUCH appreciated. BUT, if you want to ensure that I apply root.zip before booting back into Samsung mod, you should tell me to DL the file to my phone in step 1. Had to run the Odin process twice. Not a big deal, but just a suggestion.
