I was looking at the auto root for FB15 and was wanting to know if it would work for my phone, Android version: 2.3.6, Baseband: S:R760.01 K.FB14. Any help is greatly appreciated.

I've tried the ek02 autoroot three times and it's not able to push the files. SuperOneClick didn't work either.

The fb15 on this phone is ics so not going to work on your GB ROM .....maybe steady Hawkin can make you a kernel to root it with Odin ....all you have to do is ask him he may do it
He may port cwm for you too don't hurt to ask

not working
from what I hear zergrush no longer works in 2.3.6. I tried manually installing but it fails on the USCC GS2 (SCH-R760)

mostly working
So I tried it with my SCH-R760 SGS2 I was able to get root boot recovery. Having the FB14 kernel would make this a snap however the Epic 4g Touch is so close it mostly worked. I seem to have intermittent wifi problems but everything else appears to work without issue.

I got the kernel from step two WISHLINK:wiki.rootzwiki.com/index.php/Samsung_Epic_4G_Touch or directly WISHLINK:goo-inside.me/epic4gtouch/kernel/acs-eb30-clockwork-epic-touch-4g-sep-20-4-00-pm.tar

I tried sweet talking USCC, evidently I'm not as charming as I think I am they told me I'm screwed and don't yet have the re-image. However, the above has the phone working and rooted minus a few problems with wifi.

Good luck.

If you can get the E4GT kernel to boot on your phone then just use it to install su onto your ROM (/system), then put back your original USCC kernel and you'll be rooted with everything working.

So basically if your adb shell has a "#" prompt, you can just use Auto Root Option A on your phone and install root onto your phone's ROM. Just ignore the zergrush status, even though it fails, the script is still smart enough to install root onto your rom in your situation.

Then to get your original kernel back, figure out which partition has the recovery.bin, which is an unused mirror of your original kernel/zImage.

In the case of E4GT, this is partition /dev/block/mmcblk0p6

To get the mirror of your zImage type the following in adb shell
Code:
cd /sdcard
dd if=/dev/block/mmcblk0p6 of=zImage bs=256 count=32765
Now it is very important that the partition you chose above is really the recovery.bin partition, otherwise the file you just created will essentially be junk and won't allow you to boot your phone (ie *IF* you installed it, your phone *would not boot*)

Assuming you had the correct partition, to install it as your running kernel, you can do
Code:
cd /sdcard
dd if=zImage of=/dev/block/mmcblk0p5 bs=256 count=32765
Please don't go jumping into this unless you fully understand what I suggested.

YOU CAN MAKE YOUR PHONE UNBOOTABLE IF YOU DO THINGS WRONG.

I don't have your phone and the partitions could be different, so I'm depending on you to figure out if things don't make sense.

If you are unsure, ask questions before doing anything.

While I'm just understanding partitions and the like I'm able to follow your instructions but the *IF* parts I'd like to question.

I have:

/dev/block/mmcblk0p6
and
/dev/block/mmcblk0p5

I'm not sure how this correlates to the recovery.bin unless it is apart of one of those files. So for the SCH-R760 with FB14 I'd be looking for how to verify this. I can easily run the suggested lines and looks like everything is there. However to get this far it's been several hours and I'm a bit gun shy as I have to work tomorrow and actually need my phone. Again thank you for the suggestions and help. I'm very close. Everything but wifi is working and very well.

did anyone try flashing the cwm from the touch. it should work because the mount points line up the same. if so i can finish the ics rom and give it to who ever is willing to try

Can't they just odin flash or heimdall flash the kernel/recovery in, that would be easier, then they truly don't have to root the rom first.
