Do these methods work with the ics OTA
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
ICS was never delivered over the air.

Methods 3 and 4 work, but they install Gingerbread.

There is an ICS stock plus root in the Original Development forum.

Hi guys, I have been using this phone since last October and only up until recently I figured out I have the needs to root my phone. I am going abroad for a few months and I would very much like to be able to use my phone on other carriers that are available in that country.

I looked it up on how to unlock the phone and found this thread:

http://xdaforums.com/showthread.php?t=1289395&highlight=unlocking

and it requires rooting the phone in order to be able to unlock it.

What I am trying to ask here is, does rooting my phone require me to reset/reformat the phone?
[AT&T Samsung Galaxy S II SGH-I777] wgoldfarb:
Have you tried simply asking AT&T for the unlock code? If you explain the situation they will probably just give it to you.Has worked for me with almost every phone I've had. If this is the only reason you want to root, it is definitely worth a try before you attempt rooting.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I agree with wgoldfarb about unlocking it without rooting.

If you decide to root the phone, it depends on which version you currently have. On 2.3.4 gingerbread, which is the original firmware, it is easy to root and you can do so without needing to do a wipe data/factory reset. However, if you updated to 2.3.6 Gingerbread with the OTA update, or if you installed ICS using kies, then it is a little more involved to root, and you will need to do a wipe data/factory reset.
[AT&T Samsung Galaxy S II SGH-I777] sajjt:
No, if u do it properly as per creepncrawly's guide u'll be fine with all data, settings and apps.
[AT&T Samsung Galaxy S II SGH-I777] zs3889:
Thanks for the suggestions guys, will definitely go to AT&T and try to ask for the unlock code. However, I may wanna try to root my phone for some other reasons too, including unlocking it from AT&T.

My S2 is now on ICS, and as creepncrawly mentioned, rooting a ICS S2 would require a factory reset, is that true?

Thanks!

Rooting Issue

Hello All!

I'm new to the Android in general due to previously having Apple products. I was rooting my AT&T Galaxy S2(ICS 4.0.3) using DoomLord's Rooting Toolkit. The command prompt shows rooting completed, but when I read the line sequences it shows "failed" or "No such file directory". Can anyone help an Android Noob without too much flaming? :)
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
DoomLord's toolkit will not work on that version. It only works on the original Gingerbread 2.3.4 UCKH7 firmware version. To root stock ICS, flash the ICS stock plus root tar package available in the development section using Odin or Heimdall.
[AT&T Samsung Galaxy S II SGH-I777] jivy26:
Did you already flash using Odin. If so power down phone, when its off hold vol up and down buttons and hold power button when the phone turns on let go of power button and keep holding the volume buttons.
[AT&T Samsung Galaxy S II SGH-I777] moonlightme:
Done, installed Cognition 151...now stuck?

I picked up the new AT&T Galaxy S2, rooted it per instruction, and installed Cognition 151. Once in Cognition, I opened ClockworkMod Recovery, and booted into recovery mode. Now the phone is stuck in a Recovery Mode loop that simply says ClockworkMod Recovery v4.0.0.2. Selecting any option (such as reboot system now) does nothing. Perhaps I was a little too quick...any suggestions? Thank you

adb waits for the device forever. Not sure why adb is having problems. Mounts, MTP mode, ODIN, works perfect.

If I drop into the dev kit and run adb manually, it does the same thing, never finds the device. Requires some research...

Stay away from the power button. Only use vol UP/DOWN and the capacitive home button.

which method? i727 kernel ucli3 android 4.0.4

hey all~

semi-noobie question here ... I've read the first few pages of this thread [good thread I think] I admit, I HAVE NOT read all 78 pages, so if this is a repeat, I apologize. if it is, please cut me some slack and just point me to the right page of this thread. thanks!

I previously owned a samsung galaxy s captivate. that was VERY easy to root. I have since upgraded to a samsung galaxy s2 skyrocket [at&t] which is currently running android ICS 4.0.4.

baseband version: i727ucli3

kernel version: 3.0.8-1127534 [also says: se.infra@SEI-45 #1 SMP PREEMPT Thu Sep 27 23:12:45 KST 2012]

build number: IMM76D-UCLI3

I had attempted to root it previously, I softbricked it. ODIN crashed while trying to flash. so I got a copy of the stock rom and I'm back to factory.

What I wish to do is root it to get rid of the bloatware and do some tweaks like making it Ad Free. [I KNOW also, a custom ROM is pre-rooted and I could go that route]

Many instructions mention model number i777 but I have an i727. They also mention UCKK6 or UCKK7 [I imagine I'm fine there as I have UCLI3 am I correct?]

Would method 1. in the first post of this thread do the job? or would it be easier/better to simply install a custom rom like CM9 or CM10 or maybe a Serendipity (which I had installed on my captivate ... it was running Serendipity 7) or something else]

I AM comfortable using ODIN, I WOULD prefer ODIN over Hemdial or another command line method [like ADB].

So yeah, advice/ideas please? I really appreciate it :) and even if the methods here wouldn't do the trick, very nice/informative thread ... awesome job!

Hello,

I'm wanting to root my brother's SII. I have quite a bit of experience doing this sort of thing. I have read a dozen or so pages of this thread, but I don't see a clear answer: Does using method 3) in the OP require (or perform on its own) a factory reset? Or is there another way I can root without resetting? Once I have it rooted, of course we can just run TiBu.

Btw, he is on stock ICS, installed through Kies.

Thanks,

Zizzerboy
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Go to the development section and get the UCLE5 ICS plus Root package. Since you're already on that base you don't have to do a factory reset to install it.
[AT&T Samsung Galaxy S II SGH-I777] zizzerboy:
Thanks, creepyncrawly! I was going to do it tonight, but he installed the OTA update (without my permission :( ) Does that change anything?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Not really. The update is 4.0.4 and UCLE5 is 4.0.3, so installing UCLE5 will mean removing the minor upgrade. The upgrade is so new that I havn't heard if there is anything significant in it that we would want. Also, since the base is slightly different, some problems such as something force closing, etc, could arise after the install. If that happens then a wipe data/factory reset would be required. But I would try it without the wipe first and see. There's a pretty good chance it will be fine without the wipe. Just be aware it's not guaranteed, but then nothing really is when modifying phones.
[AT&T Samsung Galaxy S II SGH-I777] zizzerboy:
But can I safely do it without wiping?

hi creepyncrawly, what guide should i use to root my at&t gs2 version 2.3.6, baseband i777uckk6, kernel 2.6.35.7. w/o breaking wifi. it would really make my xmas merry :))
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You can actually use my guide and root with the UCKH7 plus root package, but you will need to perform a wipe data/factory reset to get wifi working. Or, you could root with the UCLE5 ICS plus root package in the development section, but again you will need to perform a wipe data/factory reset before flashing that.

If you want to stay on the same base, you may be able to accomplish that without doing a wipe data/factory reset by flashing Entropy's "Kernel + cache + rooted UCKK6 system package" which you can download from his thread in development. This should likely work since you will be flashing the same base, but there are no guarantees. If after flashing, you start getting force closes or other issues, you'll still have to perform a wipe data/factory reset anyway.
[AT&T Samsung Galaxy S II SGH-I777] totnak1:
OMG creepyncrawly you made my upcoming holidays so happy :))) ty so much... I'm just on stock rightnow, I don't really have any idea about roms and bootloaders and what are the benefits of them.

Don't do a wipe data/ factory reset with Stock LE5 kernel (or the Stock LK3, just as a safe measure) because of the possible eMMC brick. Odin flash the Siyah 4.3.3 ICS WITHOUT Mic Swap Kernel after u go back to 4.0.3 firmware, reboot into recovery, wipe data from siyah recovery, reboot.

Having trouble getting Galaxy S2 rooted

Hello,

I'm feeling fairly noobish, but I've tried and tried and cannot get root to work (I don't think) on my SGH-I777 (AT&T version)

I downloaded the Odin3 one-click from the first page on this thread, followed the instructions and everything seemed to work right. I got the green PASS message and the phone rebooted.

After that though, when I boot into recovery mode I don't have the options I expect. There is no "dalvik" option, and there is no ability to turn off signature verification (so I cannot load any custom roms).

What might I be missing or doing wrong? Any help is welcome!

Thanks!

-Ben
[AT&T Samsung Galaxy S II SGH-I777] Phalanx7621:
Read around . Make sure to know exactly what you're doing. You need a custom recovery to load custom roms. Which means you need a non stock kernel.
[AT&T Samsung Galaxy S II SGH-I777] benfinkel:
I know, and I apologize for the basic level of questions. I've been all over these forums and online sites.

I've used Odin 1.85 to load a kernel with CWM (theoretically) but I'm not sure how that fits in with the root process here, and not sure it made any difference anyways.

I guess I'm not finding much in the way of a general outline, what steps need to occur in what order, and how you can verify they were successful.

[Edit]

I've had some success! I had to factory reset the entire phone, and install the CWM-embedded kernel but not the Odin one-click from this thread. Then, I was eventually able to get CWM to launch (not easily though). Thanks anyways for taking a look and responding!

Baseband: I777UCLK3

Kernal: 3.0.15-I777UCLK3-CL1174199

USB Debugging is enabled

Unknown software is enabled

I tried the Exynos root at http://xdaforums.com/showthread.php?p=35469999 and the apk file won't copy onto my device, just hangs indefinitely during copying and force quits after a while.

Using Odin 1.85 I can get it to recognize my device, select the PDA but when i hit start it does nothing. Just hangs

I've run the superoneclick 2.3.3 which stops responding after clicking root.

Doomlords runme file hangs at certain points, the farthest I've seen it go was pushing superuser app, but more often than not is stops and hangs at pushing busybox.

I'm out of ideas. I tried downloading Odin mobile pro but I don't have superuser access, hence me trying to root it.

[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You don't say what you are attempting to flash with Odin. Hopefully not the .tar.gz file from the link you posted.

Get ExynosAbuse by Chainfire from here. This is an apk, and should be installed on the phone the same way any apk is installed. Read first. Don't patch the exploit or you won't be able to root.

Or... since you are on 4.0.4, you can use odin to install UCLE5 plus root from here.

It is actually more helpful for you to press the "thanks" button on posts that are particularly helpful to you. It is a way of highlighting certain posts within the forum so that others can find them more easily.
