[AT&T Samsung Galaxy S II SGH-I777] illmac:
I'll clarify cuz I had the same problem (massive brain fart). When he says step #6, it is not Step 6 in that step by step guide. When you're rooting it with SOC, it'll hang on the 6th part, that's where you unplug, clickity click, then plug again
[AT&T Samsung Galaxy S II SGH-I777] Kadin:
One thing I'd like to say about the instructions is that the big red lettered part about it stalling at step #6 I took to mean number 6 of your steps, not '#6' as listed in Super One Click. I finally put 2 and 2 together and then proceeded to disconnect the cable, check/uncheck USB Debugging and rooted fine.

Not sure if that's confused anyone else but just wanted to post some feedback for ya OP.

Anyhow, thanks a lot for posting this! :D

FYI, thanks to Jivy26's /system dump, we now have rooted /system images that are flashable with Odin/Heimdall. Flash it and you automatically have root.

In a few days we should have root-injection kernels too. (A kernel that will auto-root your /system when you flash it.) I'm trying to find a clean example of root injection that wasn't part of a Voodoo Lagfix package to integrate into my initramfs.
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
Nice! this is exciting news! Has anyone tried rooting(via Odin) Heidmall on a Mac? I run windows 7 as a parallel on my Imac but Odin gives me fits when using it sometimes and don't wanna take a chance it fails during flash :(
[AT&T Samsung Galaxy S II SGH-I777] moonlightme:
Any good roms available yet? I can tell you from experience not to use the Cognition 151...my own fault though its for a different phone. In any case, if anyone has info on a good rom (i know its early), please pass it along.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
If Heimdall on Linux works (and I can tell you it does, as that's how my prerooted unbrick packages were tested), Heimdall on Mac should work. My unbrick package even includes instructions for commandline heimdall in the first post.

CM7 beta, Cognition port beta. Although our stock ROM is actually pretty good if debloated a bit. A lot of the AT&T crap is uninstallable, but to really debloat you need to remove some other stuff to get all the running services to go away.

I manually debloated by removing APKs from /system/app and so far things seem REALLY nice. Battery life was unbelievable with a kernel that has codeworkx's cpuidle fix. I dropped only 1% in 6 hours idle last night, but that may be because my fuel gauge needs a recalibration. Kernels with this fix aren't publically available yet, but expect custom kernels to show up in a few days. I'm running one right now, but I almost never release stuff that I haven't tested for AT LEAST a day and there's still a bunch of stuff I want to do tonight to the kernel.
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
Ok, I'll look into Heidmall. I had tried to use it once before with my mac but I'm not a linux user so it was a little foreign to me. I can use it on my mac(i.e dont need windows running parallel?)

I really want to get rid of the bloat! Whenever I try to clear Ram manually in task manager it closes like 18 Apps!! WOW, really, 18, thats ridiculous!!

---------- Post added at 11:26 AM ---------- Previous post was at 11:23 AM ----------

Odin seems to work well...it goes thru the process and finally says pass... reboots and everything... But when I check in settings-about phone I still see the same baseband...
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Correct - no need for Windows/Parallels.

I would expect you to see the same baseband. Only one released baseband exists for our device.

If you use my "unbrick" package to root, you will see NO differences in anything other than the presence of the su binary and Superuser.apk - that's the whole point of "rooted stock".
[AT&T Samsung Galaxy S II SGH-I777] paleman27:
Yes!...I know what you mean now! It worked!... is the STEP 6 of the super one click NOT the STEP 6 of the instructions!

---------- Post added at 12:03 PM ---------- Previous post was at 11:39 AM ----------

I did too. How do I get rid of it? I read something about jig, but sounds complicated...
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Jig, or flash the stock kernel. It will always appear if you have a non-official kernel. The bootloader seems to only care about kernel flashes - I think if you flash a rooted system image it won't consider this to be a "Custom binary".
[AT&T Samsung Galaxy S II SGH-I777] hussarfilms:

then i tried it using the button method and it gives me the error

Man. i already miss the old days of putting update.zip on the system, and booting recovery from that!
[AT&T Samsung Galaxy S II SGH-I777] paleman27:
Ok. This is what worked 4 me: Once you reboot into recovery from the ROM manager app you will get the android dude with the "!". Next press volume up+down, that will take you cwm menu, scroll with volume up or down to your choice then press the home key (the one with the little house on the bottom of your phone) to select.

Does this Kernal support BLN? I'd like to stay as stock as possibly right now other than root and the ability to use BLN. I don't want to flash any ROMs or different kernals if I don't have to. I grew tired of continuous issues I had with my captivate
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Right now, if you use my Unbrick and then remove /system/xbin/su and /system/app/Superuser.apk, you'll be 100% stock.

In a day or two I'll add non-rooted stock packages.

No. None do yet and the touchkeys are one of the main differences between our device and the I9100. I haven't had a time to look in much detail, but I think we may have the same touchkey hardware as the Infuse, which is Bad News for BLN.
[AT&T Samsung Galaxy S II SGH-I777] jivy26:
To return to stock you need to download the file in this post and get use with Odin.

http://xdaforums.com/showthread.php?t=1286432

You need a jig to remove that. All it shows is that you've flashed a custom binary in download mode. If you notice in download mode there is a counter of how many customs are flashed. If you flashback stock exclamation goes away.

[AT&T Samsung Galaxy S II SGH-I777] paleman27:
You have to disable it and enable it again before plugging it back. It sounds silly but it's how is done.

So... 1-unplug then 2-disable then 3-enable then 4-plug it back... all this without closing the SOC (leave it running when you unplug)

[AT&T Samsung Galaxy S II SGH-I777] othermark:
I had adb working for my captivate, but it wouldn't find the AT&T SGS II with superoneclick. I fixed it by deinstalling the old drivers in add/remove programs and installing this:

Samsung development USB drivers

Which I suppose is somewhat of what Kies installs as well.

You have to register on the samsung innovator site to download it.

EDIT: read the source on the download page and composed a direct link from the javascript -- should let you bypass registration:

The OP should probably link to the Dev forum post instead of directly linking to the file. The version in this post doesn't work for CWM related activities due to button mapping. In addition, as the kernel is updated, this one will continue to get stale.

I was wondering something though. I wasnt able to overclock with setcpu. Is there something else i need to do?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Overclocking requires kernel support. No kernels exist yet with OC support.

codeworkx added OC support to the Cyanogenmod kernels, but you usually can't use those with stock-derived ROMs. I don't know what his plans are for the CWM kernel.

I'll be releasing a kernel in a few days (once I've had more time to test/develop), however the initial release will not have OC or voltage control. I'll eventually add voltage control but have no plans to add overclocking - too many stability problems.

Also be careful setting screen-off profiles in SetCPU with frequencies below 800 MHz. There's a known issue with how Samsung CPUs go to sleep that can cause "sleep of death" issues with screen-off profiles limiting frequency below 800. There's a kernel fix I'll be pulling in eventually but I want to try and reach netarchy first, as there's one oddball thing about the code that I've seen so far.

Not yet. I don't plan on creating an OC kernel, you might see one from codeworkx.

Um, stock on our device is 2.3.4, not 2.3.5. Do you have an SGH-I777 (AT&T GSII) or GT-I9100 (International version)? If you have a GT-I9100 you are in the wrong place. This is for the AT&T variant, SGH-I777.
