Root and recovery - AT&T Samsung Galaxy S II SGH-I777

Hey guys. I just got this phone for my nephew. I want to root it and rom it. Right now it's running gingerbread, which let's face it, is garbage! I am pretty sure towelroot will do the root for me, but I don't see a recovery thread anywhere? Any help here would b great, and much appreciated.
Thanks,
Zound

Please refer to the search function there is a long thread on rooting and flashing roms for the i777

You can use Framaroot with Aragorn exploit to root.
This phone does not have a separate recovery. It's built into the kernel. You must flash a custom kernel containing recovery. If you are 100% certain the phone has gingerbread, then flash the tar version of Siyah 2.6.14 Kernel using (preferably) Mobile Odin pro or Mobile Odin lite (free), or you can flash it with standard Odin3 v1.85.

[Q] Please Help Need Simpler Way to Root Galaxy S2

I was using odin, superoneclick and kies to root my phone. All was working fine untill superoneclick decided not to open and had an error message that said "Unable to find the version of runtime to run this application." I couldn't find a way to fix it after multiple attempts so I decided to try the easier way of rooting the phone. But this requires my firmware which is KDD but I can find the thread for it. Does anyone have the thread for it or help me find it. PLEASE help is greatly appreciated I have been doing this for more then 4 hours im getting really frustrated.

I rooted mine by flashing the lightning rom through Odin. The rom is already rooted. Even if you don't want to use it at least you are rooted and can flash other stuff now

Help with stock kernel to root, and CWM.

Hi, is there a completely stock kernel with root and CWM that I can flash with Odin, on my S2. I have seen a couple kernels but they have things like different boot animations, and different little tweaks but I just want stock ROM with root and CWM. I have never used Odin before, and was also wondering if rooting,and installing CWM with Odin is safer than using SuperOneClick, then using Odin to install CWM? Any help would be appreciated thanks.

1. stock kernel with root? Yes.
2. stock kernel with CwM (and root)? Probably yes.
Read this thread: http://forum.xda-developers.com/showthread.php?t=1285823
I have not personally gone with that option and I believe most of members here do not go with this option. So, I don't know if it works as expect or not.
3. custom kernel with CwM? Yes. So far in this room, there are 2 most popular custom kernels, Entropy's Daily Driver and Siyah kernel.

Rooting S2

Hi! I attempted to root my S2 via a method I found here whereby I flash an insecure kernel then root using S2 root. I followed the guide to the T and still my phone is only ''partially rooted'' according to rootchecker and no root apps could be granted su access.
I am running ICS 4.0.3, Baseband Version XXLPS.
What should I do next or should I accept defeat and leave this phone unrooted? What could I have done wrong?
Thanks in advance for reading.

flash the latest siyah kernel v3.4.1 either from ur recovery (use siyah .zip file) or thro Odin ( use siyah .tar file) and then see
Thanks Sun!
I have downloaded the Tar file. I assume what I do now is flash it onto my phone and retry S2 Root again?

If you flash Siyah you will be already rooted.
Ah, then perfect. Thank you!

Either I am an uber noob or there is something wrong!
I downloaded the Siyah 3.4.1.tar kernel from gokhanmoral and flashed via odin and the phone sat at the boot screen with the little yellow triangle on it. I left the phone on and running like that for 10minutes.
I flashed my insecure kernel back on from last time (the one I used when trying to root using s2root) and it is fine again.
Anywho I am back to square one! -.-

ok buddy follow this steps to reroot ur phone in a proper manner.
1) Dwnld the official ICS firmware(4.0.3) and flash thro odin
link Here
2) after that please dwnld the Matching Cf- root kernel and flash thro' ODIN
link Here
ur phone will be rooted properly and should wrk fine
ps- read the OP of both the threads carefully and follow the instructions over there to root ur phone successfully
If you only need proper root, no custom or insecure kernels and no yellow triangle, look at the guide in my signature. Worth the try

Hey i had a similar problem. There is a superuser n buybox zip file that you will find on one forum here,that is about basic how to root. Copy those files to your phone then go to recovery and apply zip. I had a hard time with my phone partially rooted but thay solved it

[Q] Flash siyah v5.0b2

Hi I am rooted on stock android 4.0.4 and I seem to have the brickbug (checked with gotbrickbug app).
So I want to be safe and flash the new siyah v5.0b2. Can anyone tell me where I get a temporary cwm to flash it and if this is possible? I don't want to use odin and get this annoying yellow triangle again.
Use rachmat3's method. http://forum.xda-developers.com/showthread.php?p=22626294
Siyah 5.0 is still in a development stage so you MIGHT face a few bugs which would scare a guy trying this out the first time around.
BTW, you can knock off the triangle using chainfire's triangle away app.

I tried now but the attached cwm file from this thread was not working for me. Anyway I found a mobile Odin app, can you recommend it?
You can try the methods mentioned in this post.

Be sure to read each one carefully before taking the plunge though.
Yeah, mobile Odin is an option. But I've never used it myself so can't comment. Personal subjective opinion, I prefer using the standard Odin 1.85 and then chainfires triangle away. Simple, quick and painless.

I always Mobile Odin. For flashing ROMS, kernels and basebands. It never failed me. Just make sure that you have the latest and greatest. Some 3.xx version (.10 I think) caused some problems). 3.45 is the latest I think.
If you really want to be safe, go with Siyah 4.1.5 (Latest stable).
