754Okay, 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,should suffice to do that. You'll end up with the following files:Code:tar xf <image>.tar
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:aboot.mbn boot.img cache.img.ext4 NON-HLOS.bin recovery.img rpm.mbn sbl2.mbn sbl3.mbn system.img.ext4 tz.mbn
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.)3Does this method trip the flash counter?
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.

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.2
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.
