Your warning indicates this is for " AT&T GS3 ONLY" but there are several references to Sprint throughout the instructions.

Thanks for the writeup though. :good:

Sorry, this is for the at&t galaxy s3. This guide was originally written for the Sprint but I replaced CWM 6.0.1.2 with 6.0.1.4 to make it compatible with the at&t. The rest is identical. I thought I had cleaned up the guide. I guess I missed a few references. I will clean it up after work tonight to get rid of any confusion. Thanks very much for the heads up...

Is this confirmed working? A buddy hat work upgraded his ATT S3 to JB and he wants root back.

Thanks man! Followed the guide on GalaxyS3Root.com after updating Jelly bean and it failed. This one works perfectly on my AT&T GS3! Cheers!

Don't even know if you use the same files.
Yes and no - you need to extract the individual files from the .tar image in order to use the image with Heimdall. Unfortunately, not having gone through the entire process myself in that fashion, I can't really comment on which files match up with which Heimdall options, though I may look more in detail into that at a later date.

No worries Skunk Ape1. I just haven't been able to find a guide for 4.1.1 on mac.

Okay, I've taken the time to tinker with Heimdall a bit to get the partition identifiers from my own phone (which matches up from the info from this old thread), and have put together the following, which seems to work for me. This was with Heimdall 1.4-rc1; I think earlier versions don't accept numeric identifiers.

You'd probably better have a plan on hand to get things back to normal if this doesn't work (I'm not responsible for your bricking your own device if this doesn't work).

You'll need to extract the .tar image before using this; if you're at a command line,
Code:
tar xf <image>.tar
should suffice to do that. You'll end up with the following files:
Code:
aboot.mbn
boot.img
cache.img.ext4
NON-HLOS.bin
recovery.img
rpm.mbn
sbl2.mbn
sbl3.mbn
system.img.ext4
tz.mbn
Afterwards, boot your phone into download mode (from a powered-down phone, Vol Down + Home + Power Button until you see the Samsung logo) and make sure you're completely ready and have backups and all before you run the following (I'm not going to be held responsible for you bricking your own phone and being unable to recover from it afterwards):

Code:
heimdall flash --1 NON-HLOS.bin --3 sbl2.mbn --4 sbl3.mbn --5 aboot.mbn --6 rpm.mbn --7 boot.img --8 tz.mbn --14 system.img.ext4 --17 cache.img.ext4 --18 recovery.img

You should be able to get away with flashing only some of those images instead of all of them (in particular, if you have a third party recovery from somewhere, you might want to omit the recovery image); that said, if you're only flashing some of the specified images as opposed to all of them, I'm almost certain it will trip the flash counter. (I don't know if flashing *everything* will trip the flash counter or not, though, seeing as I deliberately did not flash the recovery during my own test for ease of restoring my phone to its normal happy state.)

Already hit the thanks button once, but wanted to formally thank you for this super easy root/recovery guide! Less than 5 minutes and done! Thank you!

    Does this method trip the flash counter? :confused:

    Yes it does. But it's not an issue. Just run triangle away just before going back to stock and it will reset you back to zero.

    See the instructions to unroot and return to stock.

    Jelly bean ?

    Yes... It will work with Jellybean. This method does not install a prerooted image tar. So it will root whatever Is on your phone without any regard. It simply installs custom recovery and root.

    No problem... the at&t guys on Android Central have been using my guide to root their phones for quite some time now. So I know it works. Glad you were successful. :D
