Is there a way I can root without downloading a whole rooted ROM? I don't want to do that for copyright reasons.

I searched and couldn't find an up-to-date insecure kernel for the E4GT (there is a ClockworkMod one from last year, but I expect that's too old). Since kernels are under GPL, modifying and re-distributing them (with source) is fair game.

p.s. I don't want this thread to switch to a discussion of the legal issues with copying and modifying the stock ROM. It may not be a big deal to many people, but I want to keep within the law as best I can.

Thumbs up
Ya man head over to the developers section and download the e4gauto.bat file. That will auto root you from the existing rom you're on. It updates whatever stock kernel you have with a rooted stock kernel with CWM. from eg30 kernel to fd16 i think. Just make sure you have the drivers for your phone and plug it into the usb of your pc and go into applications on your phone to make sure you have usb debugging checks and accept files from unknown sources checked. Make sure your phone is not in usb mode and follow the prompts of the batch file. when it finishes running it will r boot your phone and you will have root and a custom recovery to flash roms with.

I think this doesn't work on EL29.

What rom version do you have I believe its EL13 or lower sfhubs method does not require a rom to be downloaded...

Edit: sorry started this post 10 minutes ago and just saw responses... then your answer is No

Based on your previous thread, you want your *initial* root to
1) avoid yellow triangle
2) avoid flash count
3) avoid using rooted ROM
4) root a ROM where there is no existing exploit

This is not possible.

If you are willing to concede on 1&2, then just ODIN flash any GB-based kernel repacked with CWM. They will work with any GB-based ROM. It will trigger the yellow triangle and increase your flash count. You will need to reset those by other means if you care about it. Either USB jig or upgrade to ICS and use Triangle Away.

I actually don't care about 1, and I am willing to concede on 2, now that my 14-day in-store return period is almost over and I'm pretty happy with the phone (except maybe for a pinkish tinge along the middle section of the phone with the brightness turned very low with ScreenDim), which is why I asked this in a new thread.

I assume nobody has had any problems with flash-count and warranty service?

Where can I get an appropriate, safe, non-bricking GB-based kernel repacked with CWM?

Can I use Odin to back up the original kernel and restore it after rooting?

Most of the time no problem, but sometimes yes. Depends on who you get.

ODIN doesn't do backups. Your stock kernel is available in the Auto Root package (Option C) or in the Individual Components Reference Section (2nd Post) of the appropriate ODIN OneClick thread in my signature, provided here for your convenience:

Does the jig work to reset flash count on 2.3.6? One site that sells jigs says it only does that on 2.3.4 and below.

Presumably, I can also build it from source. :)

Go Spend $2 on ebay for a USB Jig. Best two bucks I ever spent.

By the way, I had a quick look at Samsung's official warranty information, and it says nothing about it being voided by rooting or other unauthorized modifications. Of course, it exempts "defects or damage resulting from improper testing, operation, maintenance, installation, service, or adjustment not furnished or approved by SAMSUNG", but that's only applicable when the damage results from rooting.

Of course, Sprint does have the authority to cut off one's service for rooting (or for any other thing they see fit).
