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.
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
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
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.
