Please search and reads before posting. CF-Root is an I9100 kernel, it has nothing to do with I777.

How to root the device is already covered in the FAQs, stickies, and creepyncrawly's guides. Read them please.
[AT&T Samsung Galaxy S II SGH-I777] elbermu:
Surprised, took me an hour to root my device, flash a kernel with cwm and install AOKP, all found in xda, and a little help from CM7 install guide. The only problem I found was that in my previous post.

Cool story!!!

Phone is freezing and restarting

My Sgs2 keeps freezing to where I have to remove the battery and restart it , to get it working again. Should I return to stock ? If so where do I get that file, I've tried the one on the first link this thread but no luck with the megaupload links. I've factory reset it and it's still not acting right. It's really laggy, still freezes and some times reboots itself. I don't know what to do.

:confused:
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You could first try a wipe data/factory reset, but you will lose all your installed apps, and personal settings. Or if you don't want to try that...

You don't say what you're running currently. If you are on a custom rom and have ClockworkMod Recovery, then just reflash the rom, or pick another one to flash. If you're on stock, then reflash stock. If you reflash the same rom or the same version of stock (UCKH7 or UCKK6) then you will probably fix your problems and be able to get by without a wipe data/factory reset. But after you flash, if the problems persist, then do a wipe data/factory reset.

You should be able to download what you need from my Download Repository. See link in my signature.

I'm assuming this has been answered. But I can't seem to find it. After rooting my wifi doesn't work. Is there a way to fix this?

Wipe data/factory reset.
[AT&T Samsung Galaxy S II SGH-I777] Russellmania:
Been doing a lot of reading and searching (I have like 20 tabs open right now haha) and the one thing I'm still not totally clear on is if I flash "Kernel + cache + rooted UCKK6 system package" on my 2.3.6 stock phone using Odin, will I have to do a full wipe? I know when flashing a UCKH7 package that wifi will be broken and I'll have to flash CWM and a new Kernel (along with full wipe) to get back to working order, but I'm not sure I understand what going straight to the UCKK6 package does.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
As long as you are not changing to a different version, it is very likely you can flash without a wipe. So UCKK6 to UCKK6 should be fine. Try it and see. If you do happen to get force closes or other problems, you can still fix it with a wipe.
[AT&T Samsung Galaxy S II SGH-I777] Russellmania:
Well I'm not even rooted yet and want the opportunity to do a TiBu before I have to wipe so I'm just trying to figure out the safest method.

Edit: Nevermind, I just flashed using step 2c of Creepy's guide and the 2.3.4 package.

Siyah Kernel

After trying out about 9 different ICS Rom's i decided to flash back to UCKh7 Gingerbread and leave my phone alone. It is still rooted and I just updated it through Samsung. I have Android version 2.3.6 and kernel version 2.6.35.7 What I am wondering is if the latest SiyahKernel v3.2.4 will work for Gingerbread and the version I am using? Sorry if this is noobish and I do not claim to be an expert in any way. I just played around in here for a few weeks and now want to have my phone stock but with the best performance possible without moving away to far. Thanks in advance for any suggestions...
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Siyah 3.2.4 is for ICS only. There is a Siyah for Gingerbread. The latest version is 2.6.14, and you can find the thread on about page 3 of this forum. Or you can use Entropy512's Daily Driver Gingerbread kernel, which is also in this forum.

Question, can we download Rom Manager and flash CWM recovery after flashing this with Heimdall?
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
Right now its not recommended to use Rom manager as there's no ATT SGS II support within it, yet! If you want CWM you can flash codeworkx
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
No.

My experience with the Infuse (and it will probably remain the same with the GSII) is that ROM Manager recovery often has problems. ROM Manager caused all sorts of softbrick issues with the Infuse.

The way many Samsung phones work is such that the recovery partition does nothing - only the recovery in the kernel's initramfs matters. So the way to install CWM on a Samsung device (definitely the Infuse and AT&T GSII) is to flash a CWM-enabled kernel.

CWM is usually the first feature added to any custom kernel. Codeworkx's kernel includes CWM, I'll probably be posting a CWM-enabled kernel in a day or two.

If you want to, you can flash this system and codeworkx's zImage in one go - then you'll get CWM and root without needing to do the SuperOneClick steps.
[AT&T Samsung Galaxy S II SGH-I777] abacon15:
Okay, I was trying to use this because I have a mac and therefore have to use heimdall, but I appreciate it. Heimdall on my comp didn't like the package anyway so that saved me some trouble, thanks!
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
Nice. I was waiting to use mine to decide which method I wanted to use (and maybe wait on some ROMs to appear, but I may stick with stock rooted until someone makes an AOSP). This sounds good.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Which package?

Do you mean the heimdall frontend GUI? I have little experience with that - I always use the command line and included instructions for the commandline version of heimdall in the first post here. In fact, heimdall was tested on a Linux box before Odin was tested with these packages. :)

Siyah kernel 2.6.14 comes in both CWM and Tar versions. Mobile Odin will not be able to see the kernel in the CWM version, but it will see the kernel in the Tar version. Put the Tar version on your sdcard, and flash it with Mobile Odin should work fine.

Thanks guys for your help. I did flash the kernel and now have no wifi. Any ideas or suggestions?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Your sequence was... first flash back to stock UCKH7 rooted and then flash siyah kernel 2.6.14. Wifi worked before you flashed siyah but not after? Were there any other changes in between?

I have not seen anyone report wifi failing with just a kernel flash from UCKH7. Typically, wifi fails when flashing from UCKK6 to UCKH7, and the remedy is to do a wipe data/factory reset. Doing a wipe data/factory reset may be worth a try in your case also, but whether it will clear the problem is unknown (to me.) If you have a lot of personal settings and applications that you don't want to lose, then you should take notes and use titanium backup first.
[AT&T Samsung Galaxy S II SGH-I777] gefox4vn:
Sorry, but the link of multiupload is death :(. Could you reup to dev-host please.

And one mor question to Entropy: UCKH7 in tar file just have factorys.img and zImage but UCKK6 in tar file have 2 more file cache.img and hidden.img, what different of them :D. Do you have UCKK6 no root, please reup for me

---------- Post added at 04:05 AM ---------- Previous post was at 03:58 AM ----------

I got this problem yesterday. I flash back to stock UCKH7, and I can't use Wifi or USB tethering, everything else is ok. Then I flash Siyah 2.6.14 kernel and get some problems:

- Home button become back, back and search button is no respond

- Can't use USB and wifi tethering

- The phone signal is very good, but can't communication to that devices (I speak to friend, he can't hear me and he speak to me, I can't hear him).
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Alternate links in the Download Repository. See link in my signature.

He never posted one without root.

Are you sure you have the AT&T SGH-I777? Your profile says you are in Hanoi, Vietnam? If not, then you are in the wrong forum and flashing the wrong firmware. Sounds like it from your problems.
[AT&T Samsung Galaxy S II SGH-I777] gefox4vn:
OK, I downloaded, thanks you :D

Sorry, because I see that Entropy give this: Kernel + non-rooted UCKH7 system package: http://www.multiupload.com/I1G8F47TQ8

and I can't download from multiupload, so I think that is stock rom non root.

I'm sure about that, I'm in Vietnam but I buy i777 from a friend with UCKK6 stock non root rom. I try to root by your UCKK6 root link and flash Siyah 2.6.14 kernel by MobiOdin Lite and has the same problem.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Yes, he originally made UCKH7 stock package when the phone first came out in October, both with root and without root. But when UCKK6 came out, he only posted one with root, but not one without root for UCKK6.

Then your problem is probably a mismatch between the frequencies that the I777 can handle and the frequencies available in your country. This is not my area of knowledge though. You might want to find out exactly what frequencies the I777 can handle, and then compare to the available radio signals in your country. You can change the modem, but the I777 can only use modems made for the I777. The international Galaxy SII I9100 works all over the world, but you can't use a modem from the I9100 as far as I know. I see posts from people using the I777 in South America, India, and some other places.
[AT&T Samsung Galaxy S II SGH-I777] gefox4vn:
Yep, I think that is correct reason for my problem, but I don't understand why when I use Siyah kernel, Home button become back button and Back, Search button become not respond. Does Siyah kernel just use for i9100 internation (because i9100 just have only 3 buttons) ?
[AT&T Samsung Galaxy S II SGH-I777] gefox4vn:
Now I find one more bug:

I use PIN or Pattern to lock for my i777. But when i touch the screen until the light off, then I press Power button, there isn't any ask security on the screen, you can use my i777 without lock pass need :(. I'm using stock UCKH7 root and install MobiOdin Lite, up Entropy512's kernel DD03072012.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You need the siyah Gingerbread kernel modified for I777 from the I777 development forum (this forum). I think you installed the wrong one. Just reinstall the right kernel from here.

---------- Post added at 09:16 AM ---------- Previous post was at 09:14 AM ----------

Someone else will have to tell you how to deal with this. I think this was a bug in the original release.
[AT&T Samsung Galaxy S II SGH-I777] gefox4vn:
I used Siyah kernel 2.6.14 for Gingerbread, but i had those problems.

Anybody confirm for me that in stock UCKH7, i777 can't use USB or Wifi hotspot tethering?? And no option to turn on NFC on stock ???
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Then you might try Entropy512's Daily Driver kernel. This phone does not have native support for nfc, but Entropy built it into his daily driver kernel at some point, so the latest versions should have it. But it still does not support Google Wallet.

Be careful on this advice. As stated in that post, in the OP..

There is no mention of AT&T SG2 I777. I would suggest asking in that thread, if it will work with the I777 first.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Seriously? When Entropy has been recommending heimdall command line version for I777 from the beginning, especially for Linux and Mac?

I have successfully used heimdall command line on Windows 7 to flash my I777.
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
Same here. I actually prefer command line heimdall over Odin. More reliable than Odin, IMHO. It surely works on the I777, in fact, that how I rooted my phone in the first place(Entropy's rooted stock package) via Heimdall. :D
[AT&T Samsung Galaxy S II SGH-I777] TonyStark R.I.P.:
I agree except when it comes to people having problems understanding the whole flashing realm. I will always have somebody try the easiest way first. I have found people trying to use heimdall have a much more difficult time dealing with the set up and commands. especially when they are trying to get away from flashing. It appears to me the chap in question is having difficulties figuring out any of this and wants to get away from it.

Sorry I should have stated it different, if you feel uncomfortable using cmd line use ODIN.

Where did you get this "understanding"? As far as I know, none of the upgrades for the I777 flash new bootloaders. Some of the I777 leaked versions had a modified secondary bootloader. Did you flash one of the leaks or firmware intended for a different phone? If not, you should be fine.

Possible Hard Brick

I have a question I was helping my friend use the method in the OP to root his stock UCKK6 phone but when we ran Odin 1.7 I figured he should use the 512 PIT file it came with and that auto checked the re-partition box anyway he was stuck at

<ID:0/003> DO NOT TURN OFF TARGET!!

for over 10 mins so we unplugged battery to try again and nothing is coming on

we are going to try USB JIG

...but if and when we can get back to download mode what should we be checking off and should we even use a PIT file

I realize this may not be the thread for this but it happened while following the OP
