This happens when you flash a custom kernel with Odin3 or Heimdall. You have also incremented the flash counter. It's not a very serious problem thouigh, because you can clear the boot screen back to at&t one, remove the yellow triangle, and reset the flash counter with a jig.

Hello guys, following the guide, I rooted and installed CWM successfully, however when I try to make a selection in CWM, all it does is show the logo with the hat until I hit the power button again, making it practically useless.

I've redone the process laid out in the OP more than twice, yet the same result. The only thing that I think could be the problem is I have only 30% battery. Could this cause the stalling?

I didn't read all 50 pages, so sorry if this has been addressed already :)

Thanks in advance

edit (more detail of my problem): Whenever I enter the main CWM menu, I can never leave it without removing the battery. Whenever I make a selection, including reboot, it just shows the logo in the center of the screen (as if it's loading). When I hit the power button, the main menu returns.

I'm used to the old Captivate way of doing things. Thanks for pointing that out.

although rooting this phone for someone who is familiar with Odin is easy....and all users should get familiar with it...but if all you are looking for is ROOT and do not intend to flash custom firmwares then ZergRush root has got to be the easiest method hands down. There is also a unroot.

CWM Wont Let Me Install Roms or Flash ANYTHING :(

The problem started when after I flashed the recovery with Odin. When I booted into the recovery and tried to install the superuser zip file I keep getting this message: "E:cant copy META-INF/google/android/update-binary". I get this message when I try to flash a Rom: "E:Can't open /sdcard/update-unamed-1.3.1-full.zip". I've been trying to flash the CM7 nightlies and the "Unamed" Rom.

[AT&T Samsung Galaxy S II SGH-I777] Qortez1:
Yes, Odin installed clockwork without issue. The problem is when I try to flash something within clockwork be it a Rom or the su.zip. When I saw that I couldnt flash su in CWM I decided to try to use SuperOneClick to install su and it worked without issue. However the problem with CWM still remains and I cant figure what may've went wrong.

Please Help....Urgent

Hi,

I just received my ATT card, and I dont have an SD card.

I did the below

1. Power off device.

2. Hold down both vol down+vol up and plug in usb cable

3. Hit volume up and accept warning

4. Open odin

5. Choose the kernel you just downloaded and load into PDA.

6. Click start and let it run completely and boot up.

7. Completely power down your phone.

8. Hold vol up and vol down button and then hold down power button as well until you see the boot screen then release all three buttons. It will take a few, but you will boot into Clockwork Mod, you will know your in CWM because there will be a black background with blue text.

(To navigate CWM Vol Up moves cursor up and Vol Down moves cursor down. Home button selects and back button goes to previous menu.)

***********

9. Scroll down and select "install zip from sdcard" then select "choose zip from sdcard".

I CANNOT SEE the "Yes - su-3.0-efgh-signed.zip". .. How does this get loaded..

PLEASE HELP... I can come on screen share or call someone (willing to help) within the states.. am in Michigan
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Assuming you have transferred the file to the root of your sdcard successfully. The files will be at the end of the list, below the directories, and the list will be long enough that the files will be off the screen. So, use the vol up button to scroll up until it cycles to the bottom of the list, and makes the files visible.

Flashing a custom kernel with Odin or Heimdall from your computer causes the warning triangle and increments the flash counter. It's how Samsung designed the bootloaders to work.

Wifi tether only works for other wifi devices? I tried using it once, but I don't think it made me a "mobile hotspot" ( I turned that on too - MIUI-1.11.9)

I'm not sure if I had to be connected to a wifi to use it, or if I could use it from the phone alone.

I was wondering if this method (I used it on my phone after following an improper guide on galaxys2root.com) will change anything from stock that has to do with the modem/connection anything that transfers data or would alter data speed on the phone, and would it be noticable by at&t *(I figure I could undo it via my PC even if my friends phones screen broke)

I'm asking because his phones peculiar, he downloads any app or data in a second or less (the download bar flashes and its downloaded AND installed that fast!)

When I got my phone everything was quick, but his is crazy quick, and I wouldn't wanna do something to mess that up for him. He loves his phone stock :) it is good. My downloads took 10-15 seconds via data, his... Zipp :)

Why the difference? Same phone, same everything? I think its cause God blessed him, He prayed for the phone and God got him it for cheap + souped :) no joke.

So far as I know, you can root after the update by flashing a root injecting kernel. I think the zedomax rooting method works. (Warning, trips the flash counter.)

The other way to root the update, and this will work even if you have already installed the update, is to flash back to UCKH7 stock plus root, method 3 or 4 in the OP, and then check for the update, let it download and install. You will retain root on UCKK6.

[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
If you downloaded and flashed the one-click downloader linked in method #3 of the OP, and as you say, it flashed successfully, then you are rooted because that package includes root.

Go into the app drawer and find superuser.apk, then you know you are rooted, but if you can't find it, then you're not. Also look in the file system for the su binary, /system/bin/su.

Open Superuser.apk and see if it shows any root requests.

I'm brand new to this rooting thing, but I can usually hold my own when it comes to stuff like this.

I'm trying to root using method 3, but my Odin3Excution v1.81 looks different than ones I've seen in videos. It's just 8 blank boxes (2 columns x 4 rows). When I do the volume button thing, then press volume up, my phone goes into the correct mode but nothing changes in the software. I tried hitting start for the hell of it (knowing it wouldn't work), and like I figured, nothing happened.

Is there something simple I'm missing here?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
If you followed the steps in the correct order:

1) open "I777UCKH7 OCD Root No BL.exe"

2) Put phone into download mode

3) connect phone to pc using the usb

at this point the small edit box in the upper left corner should turn yellow, and say something like [0:COM8]

On some pc's, it can take some time for this to happen, maybe even as much as 30 seconds to a minute.

If evidence of the connection does not happen, then there is some problem with the connection between the phone and the pc. Try another usb port. Make sure the cable you are using is good, etc.

[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Actually, the two bulletin dot instructions should be clear enough. If you use the standard method to enter download mode, as instructed in the OP, then you must follow steps 2 and 3 in order, or actually simultaneously, even though it is only one bullet point. When the phone is stock, the only two ways to enter download mode, as far as I know, are the standard method, and the jig. The order could not get reversed with the jig because you need the usb port to plug the jig, and then once in download mode, plug in the usb cable.

The actual point about being out of order is that the Odin3 one-click program must be open when the phone is connected to the computer in download mode. If the phone is connected to the computer in download mode before the Odin program is started, then Odin will not see the phone.

I had the AT&T 2.3.6 update installed. Once you follow method #3 (or 4 I assume) to root the phone you are back to 2.3.4 and wifi doesn't work (at least it didn't for me). At that point if simple go into Settings>Software Update and let the phone update to 2.3.6 again, when it is finished and reboots you will be able to turn WiFi on and it will work correctly this time. No need to do factory reset and reinstall a bunch of stuff, much easier.

Same here.

This killed my WIFI as well.

---------- Post added at 10:40 PM ---------- Previous post was at 10:16 PM ----------

The missing step for me was a "Factory Data Reset" following the root.

Immediately after the Root alone, I too lost WiFi functionality.

WiFi setup would not find any wireless networks (of which I can normally see several). Wi-Fi would turn itself back off before anything was found and before I could manually add my network.

The USB port on my original phone shot the pooch, as they say.

When AT&T finally accepted that fact, they replaced it with a brand new phone running 2.3.4. Like an idiot, I allowed the OTA update to 2.3.6 occur on the drive home. Without knowing, this made the root a little different than my original procedure soon after launch date.

I had yet to set any account information either by exchange or by Google.

Extracting this: I777UCKH7 OCD Root No BL.7z

turned into this: I777UCKH7 OCD With Root.exe

Which successfully rooted the phone from OTA 2.3.6, back down to 2.3.4.

This is the point where WiFi was killed.

By immediately performing a factory reset under: Settings, Privacy, "Factory Data Reset", WiFi was functional again.

I was not allowed to do another OTA update because of the 24 hour wait period to "check again".

I tried, but it said my software was already up to date (which of course it was not anymore, I was back to 2.3.4).

Hope this helps others.
[AT&T Samsung Galaxy S II SGH-I777] dirtnap101:
I guess it depends on whether you prefer 2.3.4 or 2.3.6. But at the point "where wifi was killed", you have a choice. You can do a factory reset and stay on 2.3.4 and wifi will return OR you can do the OTA upgrade to 2.3.6 and wifi will return that way as well.
[AT&T Samsung Galaxy S II SGH-I777] iqak:
In my case I did the factory reset to regain the wireless 1st.
