Thanks Jivy26.

Your thread is very helpful!

I just got my ATT Galaxy s2 another day.

Downloaded all the documents you listed and followed your instruction.

Everything was fine except #6.

I stuck at step#6 several times after I plug back in with:

Protocol Fault(no status)

Finally, I followed another thread at:

http://xdaforums.com/showthread.php?t=1011355

and I openned task manager and ended up "adb.exe"

Amazing! it was rooted.

Wish my experience are useful for someone.

One more thing:

It is my first time to use Adroid cell. Do you have any recommandation on app to share my ATT's wireless to my laptop? Just like IPhone's MyWi.

Thanks again.

Help me - I have troubles with flashing ROM

I wanted to flash ROM (cyanogenmode) but I have troubles. I have flashed cwm via ODIN. Then I root CWM and thorugh every operation are a lot of failure.

For example:

E: Can´t mount /cache/recovery/command

Can´t mount /sdcard

E:Can´t open /cache/recovery/last_log

through wipe format /factrory...

E: format_volume: make_extf4fs failed on /dev/block/mmcblk0p10 (...

skipping format...

Data wipe complete.

Then I can´t find zip. file on SDcard and when I use internal SD card then there is a instalation error.

Help me with it. Now I use stock ROM KI3. Flash thorough odin was without problems. But when I want to flash ROM through CWM I have troubles.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
KI3? Stock on the I777 is UCKH7. There is no KI3 firmware for the I777.

If you own an I9100 you're in the wrong place and we can't help you.

I successfully rooted my AT&T SGS2 using this method tonight without any problems, so thanks very much for sharing this info with all of us! :)

One oddity I've noticed on my phone since doing this and I haven't seen anyone else mention after reading through this entire thread; when I go and activate Bluetooth now via the toggles in the notification bar it plays the sound file I have assigned for notifications, and makes an entry appear in the notification area that states "Bluetooth available. Open available Bluetooth devices".

This has never happened before rooting my phone, so I'm guessing it has something to do with the particular kernel used for this rooting method? Anyone else seen this on their phone?

Thanks!

To jig or not to jig....

Not to be a pain, but....

Someone on this forum says the jig will not work with the i777 (AT&T SGS II) but that you can do it with a power on button sequence and a standard USB connection.

I have that darn triangle, and am trying to locate the easiest way to get rid of it, and I can build a usb jig if shown the diagram...

Thx!
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Some jigs work, some don't. The GS2 seems to be more picky about resistor tolerances than the Cappy was. People with 301k resistors seem to be OK. People with 300k resistors don't, even though these worked OK on the Cappy.

Total newb to android after years of using an iPhone. I have a couple questions about this process. When I am downloading the different items mentioned in post #1, is this the link for the cwm I need multiupload.com/QQKN7NJAFTl ? Also, if that is correct do I leave that file zipped and just load its location into Odin or do I need to unzip it first? Sorry for.the basic.questions but I just want to make sure I do this right the first time.

I've never been failed by long power press (hold Power for 10-15 seconds, maybe 20?)

---------- Post added at 04:46 PM ---------- Previous post was at 04:46 PM ----------

Unzip it first.
[AT&T Samsung Galaxy S II SGH-I777] ORT14:
Ok. When I download it into my folder it says "SGH-I777_ClockworkMod-Recovery_5.0.2.3." Then when I open it to unzip it all that's there is a file that is marked as ".." and one that is marked as "zImage". What should I be unzipping?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
The file is not a zip file. It is a .tar. You don't need to unzip it. I sounds like you have file extensions turned off on your computer, so you are not seeing the extension? Anyway, the tar file goes in the PDA slot in odin. When the instructions say load the kernel into the PDA slot, that means the .tar file you just downloaded. BTW, the zImage is the kernel itself, is the actual file that is flashed to the correct file block in the file system to install the kernel.
[AT&T Samsung Galaxy S II SGH-I777] ORT14:

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Removing those two will unroot you.

For a complete unroot and return to stock - I've got an Odin/Heimdall flashable package in a thread in the dev forum. Flash that kernel and system image, enter stock recovery and perform a factory reset/wipe, and boom - you're returned to stock.

[Q] Difference between these 2 Rooting methods?

I ran across this AT&T SGS2 Rooting method via Google search... http://www.traemcneely.com/2011/10/08/how-to-root-att-samsung-galaxy-s2-sii-root-odin-superoneclick/

appears to involve installing/using:

1) Samsung Drivers

2) Odin

3) SuperOneClick 2.1.1

4) CWM Recovery 5.0.2.3

The method in OP (jivy26) post #1 appears to involve installing/using:

1) Samsung Drivers

2) Odin

3) SuperOneClick 2.1.1

4) Kernel from Codeworkx

So my question: what's the difference? The OP (jivy26) method seems to require flashing a kernel (Codeworkx)... while I don't see a kernel flash in the 1st method above (but does involve CWM 5.0.2.3). Does CWM flash a custom kernel too? Do both methods remove deodexed files?

Thanks... I'm a bit confused as method #1 above does not appear to involve changing the stock AT&T i777 GS2 kernel ??
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
codeworkx's kernel includes CWM 5.0.2.3 - a custom kernel is, in my opinion, the ONLY proper way to have CWM.

The orders are slightly wrong - the CWM kernel needs to be prior to SuperOneClick. Also there's a CWM-flashable su package floating around somewhere that can be used in place of SOC. Also, my custom kernel has an automatic root injection script - flash it, boot, and you're rooted, even if you flash another kernel later.

[AT&T Samsung Galaxy S II SGH-I777] jivy26:
Quadrant really means nothing. If your phone runs smooth and is not laggy that is what you should be more concerned with. Rest is just for the birds.
[AT&T Samsung Galaxy S II SGH-I777] Colton127:
I don't know why you'd want to over clock this device except for getting very high benchmark scores.

I'm running my phone on 200mhz-500mhz and are getting no lag, freezes, etc. Only some jitters when scrolling on very large web pages. I'm amazed at the speed of this processor, it's brilliant.

At 500mhz clocked, the browser is on-par with the speed of my iPhone 4. That's sad.

WARNING: DO NOT CLOCK YOUR CPU AT 200MHZ AND LOCK YOUR SCREEN - It won't unlock!

-In the event that you do this, just hold down the lock button for 20 seconds and force a reboot. Ensure that you don't have the CPU clock starting on boot!
[AT&T Samsung Galaxy S II SGH-I777] DoctorQMM:
Entropy512: thanks so much for the quick response and additional detail. Yes, I did not list these in sequential process order... was just trying to show that the 1st method (link) didn't seem to involve flashing a new kernel, while the OP post (jivy26) did... and to understand how the 1st would work without changing the kernel.

--from tegrak--

What is this?

This is for family of Galaxy S and Galaxy S II devices.

You can set maximum CPU frequency of your device on available models EASILY.

This works with STOCK kernel, STOCK rom, (x)custom kernels and roms(x).

OOPS, after Gingerbread, not available on custom kernel that modified kernel source codes(added function symbols..etc). Froyo is still possible on almost customs.

You just need to rooting.

It'll work, but you need to flash the J1 stock kernel back again if you want wifi.

Same deal as with UCKI3/I4/J1 leaks on the Infuse - the leaks require something in the kernel for wifi support not present in Samsung's source code drop.

2. Open up the Odin, click the PDA button and find your ROM.tar file and hit Start. It'll install and reboot auto-magically.

@thesilentnight: You can purchase a Jig and use it to put the phone into download mode. That will clear the warning. You'll find references to it all over the forum, maybe even earlier in this thread. Also flashing a stock kernel using Odin will clear the warning.

@greddy1 and ghstridr: It's probably you are used to the old button combinations. On this ClockworkMod Recovery, use the home button for enter instead of the power button. The power button will take you to the previous screen, or in some cases a warning screen.

@ highaltitude: go to this thread in the development section and download the Kernel + Rooted system package and flash that using Odin3 v1.85. That will be bone stock but with root access.
