[AT&T Samsung Galaxy S II SGH-I777] NoOneBetter:
Finally rooted. Couldn't get it to work on my Win 7 x64 machine. It kept on getting stuck in Odin at SetupConnection. Worked on my Win XP machine just fine.
[AT&T Samsung Galaxy S II SGH-I777] Strange8ractor:
Now we are going to flash the Kernel

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". Now go and select "su-3.0-efgh-signed.zip" then select "Yes - su-3.0-efgh-signed.zip". Now select back until your at the main menu select "reboot system now".

I got through step 8 with no problems, but when I try to choose the zipfile from my sdcard I get the following error:

E:Can't mount /sdcard/

I've googled for hours trying to find a solution to this problem with this specific phone and have had no luck.

Any help will be greatly appreciated.

FOLLOW-UP:

It turns out that the problem was due to having device encryption enabled for ActiveSync. That's why I couldn't mount anything at all from CWM.
[AT&T Samsung Galaxy S II SGH-I777] MWilkenson:
Make sure you put the zip file on the internal sd card...not the external.I had the same problem
[AT&T Samsung Galaxy S II SGH-I777] roundededge:
I've tried this method to root a number of times. However, afterwords, each time, WIFI breaks.

Anytime I try to turn on WIFI, it does a Wi-Fi network scan then turns off Wi-Fi without finding anything.

My only resolution to get WIFI to work again is to revert back to stock using I777UCKJ1_designgears_Oneclick.exe

Any ideas on troubleshooting this? Thanks
[AT&T Samsung Galaxy S II SGH-I777] Strange8ractor:
Yeah, I thought it might be trying to mount the external SD card so I removed it to be certain. The file is located at:

/sdcard/su-3.0-efgh-signed.zip

Other ideas?
[AT&T Samsung Galaxy S II SGH-I777] MWilkenson:
Eh I know I saw something in recovery mode that involved mounting but im new to this so I honestly wouldn't know what to do. Sorry I can't help you further.

Can't get into download mode

So, holding volume up + volume down and plugging in the usb doesn't bring me into download mode, it just starts charging the phone like it normally would when plugging in the USB...

Warning: complete newbie to this whole thing

i followed all of those steps and i didnt have any problems... however this is the first time i've rooted my phone... whats different? lol nothing looks different. my settings havent really changed. i dont get it lol clearly im missing something. the only thing that changed is that my phone now will not connect to my comp '_'
[AT&T Samsung Galaxy S II SGH-I777] MWilkenson:
I my self am also new to this. Rooting allows you to do a lot of stuff though. From roms to themes etc. As far as USB connectivity goes...you need to go into your settings..click applications...and click development..then select the debug option..thar will allow you to access your files and what not. If you have any more questions, pm me and ill share with you some knowledge I have gained from my friend who has been helping me along

Galaxy S2 -UnNamed-
[AT&T Samsung Galaxy S II SGH-I777] WrecklessLove:
thanks! that worked. i was about to be very upset about that lol. i guess i just may need to try another ROM. i wanted to make my phone more customizable. this ROM isnt showing me any different settings than i already have. any suggestions on that?
[AT&T Samsung Galaxy S II SGH-I777] netarc:
Have you found, as you tried various ROMs, whether the Sammy Touchwiz functionality was affected or disabled? Too, are you using your S2's hotspot/wifi tether feature, and if so did you merely delete or freeze the tether mgr and use the native tethering enabler, or are you using one which is builtin to the ROM?
[AT&T Samsung Galaxy S II SGH-I777] WrecklessLove:
Edit

does anyone know why the Unnamed ROM drains the battery so fast? my phone wont even charge now. or its charging very slowly

Problem with clockwork recovery

So i did the first couple steps in these directions and it seemed to work fine. But, when i go into clockwork recovery none of the menu items are clickable. Or rather, clicking on any of the options (reboot system now, install zip from sdcard, etc.) just brings me to a black screen with the CWM logo in the middle...I don't really know where to go from here.

Problems with CM Recovery

So I'm trying flash CM7 and having some trouble with it, mainly with CW Recovery (im assuming it is causing many of my other problems) When i reboot into recovery, either through ROM manager or the three button way, I get a black screen with the little android guy and a white triangle with an exclamation point in it. Only when I press the power button and this point does the standard CW Recovery option screen come up.

Then, at the bottom of that screen it says:

"CWM-based Recovery v5.0.2.3

Finding update package...

Opening update package...

Verifying update package...

E: failed to verify whole-file signature

E: signature verification failed

Installation aborted"

That's not normal. And, whenever I try to flash a ROM, either from the sdcard or downloading one through ROM manager it fails. I'm assuming the two are related. How should I get around this?

[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
So I've had my i777 for about a month now, and am becoming interested in rooting my phone. I'm currently in the process of doing the recommended research into rooting seeing as this is my first smartphone and I have absolutely no experience with rooting or linux. I have a few questions which I'm sure have been answered somewhere in this forum in some form, so I apologize if my questions have been answered, but I'm not good at piecing together information from various sources, plus I'm not so sure what information is fact or opinion.

Researching rooting I've come across some guides which look simple enough, however I would like to know exactly what I'm doing so if something goes wrong I can better troubleshoot it. So if someone wouldn't mind bearing with me and helping me through the process via PM, IM, or even in this thread, that would be much appreciated.

I understand rooting gains the user "root" access to the OS which gives the user certain abilities otherwise not possible. However I do not understand(even after some research) the process of "flashing". I am basically interested in freezing certain apps and removing bloatware to increase battery life, and am also interested in creating a backup.

Right now I have the following:

Model Number: SAMSUNG-SGH-I777

Android version: 2.3.4

Baseband version: I777UCKH7

Kernel version: 2.6.35.7

Build number: GINGERBREAD.UCKH7

I have downloaded Kies and updated to the latest version(2.1.0.11095_121), however on the main screen it says "Your device does not support software upgrading via Kies" and has the Current firmware version as "I777UCKH7/I777ATTKH7/I777UCKH7/I777UCKH7" is this normal for an unrooted device?

What exactly is the difference between rooting and flashing a custom ROM? I am under the impression that rooting doesn't actually change any firmware, but rather just grants the user "root" access, however it seems you must flash a ROM in order to root, I don't really want to change anything yet other than gaining "root" access. However I'm open to anything that improves my phone, stability is the most important thing to me...my phone is working perfectly ATM so I want to make sure that rooting and flashing or whatever isn't going to likely screw anything up(I know there are always risks involved, but that's the case with anything).

Thanks in advance for the help I'm sure you guys will provide, the android community seems awesome from what I've read on these forums as well as on the Android Forums.

USB Jig
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Rooting means adding superuser.apk, which is an application that manages root access, and a library of utilities to work with it. That is basically all that is done to root a phone.

Flashing means changing the actual firmware on the phone.

However, to root on the SGS II you must also flash.

I would suggest that you follow step 2a in the guide "How to Flash Custom Binaries Without Ever Incrementing the Flash counter!!" See link in my signature. (If you don't have a windows computer, then follow step 2b.) This will flash rooted stock firmware onto your phone. Once completed, your phone will be the same as it is now, plus it will have root access. If that is all you want, just ignore all the other steps. Of course, if you read the whole guide, you will learn a little more about your phone.

Yes, it's that simple.
[AT&T Samsung Galaxy S II SGH-I777] RocketSled:
As I can attest.

Got my new GS2 last Tuesday. Rooted via Kernel-mod that night. As expected, got a Yellow Triangle. Looked up on the web to see what a Jig "was". Easy enough to make one, all that's needed is a 300K resistor, a spare male micro USB plug, and maybe 10 minutes of prep and soldering. But being lazy, if I were to "make", I'd probably have one of the Techs at work do it for me. Actually, I'm super lazy. "Order with one click" on Amazon. $2. Sure I had to wait 4 days for it to show up, but I think I only rebooted once that entire time anyway so it didn't matter.

It took longer to get the thing out of the package it came in, than to actually use it to reset the counter and get rid of the triangle...

Strong recommend "just buy a Jig".
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
Thanks for the explanation very helpful, is this stock ROM like official from Samsung? How is it different from my current ROM?
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
Also, what exactly happens when you flash? Do your settings and all your data(audio, pictures, etc) erased?
[AT&T Samsung Galaxy S II SGH-I777] jbg22003:

ditto, I have the same question.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
If you mean the kernel by codeworkx listed in step 1 of the OP, then yes, you have ClockworkMod Recovery. Just copy the UnNamed install zip onto your sd card, boot into recovery, and select install from sd card.

no....

go to the CAPTIVATE section for that phone.....the i897 is the captivate, NOT the galaxy S2....

Not sure if I'm doing something wrong or I missed a step...

I'm holding vol up + down and power then it boots to "android system recovery 3e". Not asking me to accept anything. This is what it says...

Android system recovery <3e>

reboot system now

apply update from sdcard

wipe data/factory reset

wipe cache partition

--Copying media files...

Successfully copied media files.

# MANUAL MODE #

What can do from here?

***FIXED***

Now another issue... got CWM installed but it wont do anything. It shows me the options but goes to a screen with the CW logo an hangs there....

[AT&T Samsung Galaxy S II SGH-I777] jbg22003:
one more small question if i throw in Unnamed Rom, Can i OC it. or would i need a different kernel, i don't know what decides if i can OC the kernal or the Rom.

is the kernel i downloaded in this thread OC'able?
[AT&T Samsung Galaxy S II SGH-I777] iFalcon:
Okay. I am completely baffled and I have rooted Android phones before.

I booted in Clockwork, but when select apply file from zip, it immediately goes to a HAT with a orange error. I have never see that before.

Any ideas?
[AT&T Samsung Galaxy S II SGH-I777] Pirateghost:
yeah, from the OP:

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

Ahh....disgrace and embarassment on me. Sorry.

I new flashing a new phone when sick with Nyquil was a bad idea. Unnamed ROM update going smooth.

Thanks!
[AT&T Samsung Galaxy S II SGH-I777] cornfruit:
Excellent

Worked great for me, now happily running UnNamed 1.31. Amazing community.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
UnNamed rom adds a whole boatload of improvements over stock. Just read through the changelog and the rest of the OP in the development thread, and make your desicion based on that.

The best way to improve battery life is to flash a kernel that is optomized for battery life, such as Entropy512's daily driver.

In my opinion, there's nothing in the UnNamed rom that is a negative. It just improves on the stock experience. And anyway, if you decide you don't like it, you can always go back.

I think your best bet is to follow the guide step by step all the way through.
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
Is unnamed rom stable? That's the only thing I'm really worried about as far as flashing a custom ROM. I'm going to root here in a few moments, and I'll report back when I'm done. Also, by rooting via method 2a I will not be voiding my warranty correct?(Yes I know the thread title says flash custom binaries w/o increasing flash counter) I'm just really nervous.

I've been reading these boards for a solid month now, and I'm still nervous doing this. There is so much information on these boards, and I think that is a bad thing for us beginners, which method is best, which ROM is best, which kernel is best, etc...

anyways...here goes nothing...
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Techincally, you will be voiding your warranty (if I read AT&T's fine print correctly.) But if you are concerned about actually being unable to return the phone under warranty, not to worry.

My first Captivate had the random shutdown issue. I had the phone replaced under warranty, using the One-click downloader return to stock to get the phone back to original status. There was never any problem because when the phone went back, there was no way they could tell it had been other than stock. And most people believe they don't really look anyway. In fact, some people report that they have returned their phone with a custom rom still installed and had no problems.

And this guide was written for folks like you. It's almost exactly how I felt about the Captivate when I first got it.
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
Well I just rooted via 2a method, and it was I expected...easy. Yes I expected it to be easy because it looks really easy to do. It's just that I was so worried about something going wrong and I cannot be without my phone.

So far I have installed TiBu & ROM Manager. I froze a few apps in TiBu, and am now trying to make a backup in ROM Manager. I installed CWM Recovery, and when I try to create a backup it reboots into what I guess is CWM Recovery, and says the following...

--Installing package...

Finding update package...

Opening update package...

Verifying update package...

E:failed to verify whole-file signature

E:signature verification failed

Installation aborted.

What's going on? Can I not create a backup of stock ROM?

UPDATE**

Guess it's because I got CWM Recovery through ROM Manager...looking up fix now...

---------- Post added at 07:27 PM ---------- Previous post was at 07:17 PM ----------

Okay, question...I guess I wasn't supposed to flash CWM Recovery from ROM Manager...is it okay for me to follow the steps in this thread http://xdaforums.com/showthread.php?t=1285823 even though I've already flashed it via ROM Manager?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
If you follow the steps in codeworx thread, and flash his kernel with Odin3, you will increment the flash counter and wind up with the I9100 bootscreen with the yellow triangle. If that doesn't bother you, then his method is fine.

If you want to avoid that, follow my guide all the way through, and flash either codeworx kernel, or Entropy512's kernel using Android Debug Bridge (adb) from your pc, or using Android Terminal Emulator from your phone.
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
I have been thinking of installing Entropy's kernel for better battery performance, but I'm not yet comfortable installing a kernel because I don't really know what a kernel is lol...I appreciate you're guidance creepy
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
I'm want to flash UnNamed tonight, but am unsure which kernel to install. Which do you recomend creepy? I read that UnNamed comes with Entropys kernel, so what happens if I flash entropys kernel to get CWM, and then flash UnNamed when it already contains a kernel?

Also, can I flash Entropys kernel with CWM even if I already tried to flash CWM through ROM Manager?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You can start with Entropy512's kernel, but you can't flash it from stock 3e recovery. You would have to extract the zImage and flash from heimdall command line, adb or Android Terminal Emulator. Once you have ClockworkMod Recovery, you can flash UnNamed over it. I think latest version of Unnamed also has the latest version of Entropy's daily driver, so at that point, you are good. If you are concerned about the yellow triangle and the flash counter, see my guide.

Re: Rom Manager, I think you will be ok, but of course I've never tried it, so can't say from experience.
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
Is adb this (http://developer.android.com/sdk/index.html)? I'm at step 3a of your guide, and I'm confused as to how to change the directory to the tools directory...also when you say enter the following into command prompt, do would you for example enter "adb push zImage /sdcard/zImage" then push enter, then enter the next line? Ive never really used command prompt.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Yes, that's the same link as in my guide. Once installed you need to know what the exact path is to the sub-directory where adb.exe is installed.

Using the command prompt:

What OS are you on? On windows 7 for instance, when you open the command prompt, you will get C:\Users\Your User Name>

Type "cd\" and hit enter. You will get c:\> (cd means change directory)

Type cd android-sdk-windows\platform-tools and enter. You will get C:\android-sdk-tools\platform-tools>

Of course, the actual path directory and sub-directory will have to match what you have installed on your computer. Now you are ready to enter adb commands.

Then follow what you said and you will be good.
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
For some reason it wont let me install android sdk to the c drive only to like c:\programfiles how do I cd in DOS to the sdk if it's installed under program files?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
First write down the full path to the directory where adb.exe is located.

Then follow what I wrote above, but use the path you just wrote down.

The path will be something like C:\program files\.....\..... (whatever your actual path is)
[AT&T Samsung Galaxy S II SGH-I777] Pirateghost:
cd "c:\program files\android\blah\blah"

OR

open up the folder in windows explorer, hold down SHIFT and right click in the folder and click OPEN COMMAND HERE

I'm very nervous atm but feel better knowing you're there haha...I'm about to install entropys kernel and then gonna try to flash unnamed, are all my apps and settings going to get erased? I made backups of some apps and some of the stuff in that newbie guide to tibu...
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Yes they will. When you before you flash UnNamed, you need to do a wipe data/factory reset. This will remove all your personal settings and applications. Be sure you have everything you must not lose backed up first. Relax, follow the instructions and you'll be fine.

I'm going to bed now.
[AT&T Samsung Galaxy S II SGH-I777] Jonnyredcorn:
Ok success, I believe I flashed the kernel because now CWM works and I just created my first backup...I'm downloading unnamed v1.3.1 full right now (280mb) and will be flashing when finished.

What should I know before flashing? If something goes wrong, now that I created a backup I will be okay right? Will I have to redo my settings and redownload my apps?
